Review: The best password managers for PCs, Macs, and mobile devices

10 local and cloud-based contenders make passwords stronger and online life easier for Windows, OS X, iOS, Android, BlackBerry, and Windows Phone users

Thanks to a continuous barrage of high-profile computer security scares and reports of cloud-scale government snooping, more of us Internet users are wising up about the security of our information. One of the smarter moves we can make to protect ourselves is to use a password manager. It's one of the easiest too.

A password manager won't shield you against Heartbleed or the NSA, but it's an excellent first step in securing your identity, helping you increase the strength of the passwords that protect your online accounts because it will remember those passwords for you. A password manager will even randomly generate strong passwords, without requiring you to memorize or write down these random strings of characters. These strong passwords help shield against traditional password attacks such as dictionary, rainbow tables, or brute-force attacks.

Many password managers allow you to automatically populate your password vault by capturing your Web logins using a browser plug-in and allowing you to store these credentials. Other options for populating your password database include importing an Excel spreadsheet or manually entering your login information. Further, using these stored credentials is typically automated using a browser plug-in, which recognizes the website's username and password fields, then populates these fields with the appropriate login information.

Although several browsers offer similar functionality out of the box, many password managers offer several benefits over the built-in browser functionality -- including encryption, cross-platform and cross-browser synchronization, mobile device support, secure sharing of credentials, and support for multifactor authentication. In some cases, usernames and passwords must be copied from the password manager into the browser, reducing the ease of use but increasing the level of security by requiring entry of the master password before accessing stored login information.
6 simple tricks for protecting your passwords

Some password managers store your credentials locally, others rely on cloud services for storage and synchronization, and still others take a hybrid approach. Some of the options using local storage (such as KeePass and 1Password) still support synchronization through Dropbox or other storage services. Deciding which password manager is best for you will come down to features and ease of use, as well as to whether you're comfortable storing your passwords on the Internet.

If having your critical data stored in a cloud service worries you, then KeePass, 1Password, or SplashID Safe (sans SplashID's cloud service) offer the top options. If you trust cloud-based services with your passwords and believe they will protect your data using good security practices and encryption, then LastPass, Dashlane, or PasswordBox are your best bets.

In my judgment, KeePass is the best of the options using local storage. The fact that it's open source, free, and complemented by countless plug-ins adds up to a very flexible option. With the right combination of plug-ins, KeePass can be made to do almost anything you could require of a password manager. My favorite cloud option is LastPass, primarily due to its low cost and the consistent implementation of features across all of the clients. Each LastPass client I tested was easy to work with, stable, and remarkably uniform from a usability perspective. Additionally, the fact that a LastPass Premium account is all of $1 per month makes it an extremely compelling option.

But one of these other options might suit you better. Really, you can't go wrong with any of these password managers.
1Password

1Password is the brainchild of AgileBits, maker of the popular Knox encryption tool for OS X. Unlike Knox, 1Password offers support for multiple platforms, including Mac, Windows, iOS, and Android.

Like KeePass, 1Password uses a local file to store encrypted passwords. AgileBits does not provide a cloud service for synchronization with mobile devices, but 1Password does support synchronization of the password vault using Dropbox (all platforms) or iCloud (Mac and iOS only). 1Password also supports synchronization over Wi-Fi between Windows, Mac, and iOS clients. Because the 1Password vault is contained in a single file, you gain the convenience of a portable password vault without having to store your passwords on the Internet.

1Password clients allow you to create and maintain multiple password vaults. Multiple vaults can be used to share some of your passwords with another family member or co-worker. Secure sharing between 1Password clients is supported, giving you a method to transmit a login (or any sensitive information, such as a credit card number or the answer to a website's security question) to another licensed 1Password user over an encrypted channel. Emailing login information in plain text is also supported, but this information is only as secure as your email traffic.
1Password favorites

1Password stores your passwords in a local file, but supports synchronization across devices using Dropbox and iCloud.

1Password now provides a number of different tools that analyze your passwords and the services they secure in order to identify potential vulnerabilities. Though many websites have patched the Heartbleed vulnerability by now, 1Password takes the precaution of comparing your last password change for a site against the date the site’s server was patched. If your password hasn’t been changed since the patch, 1Password will encourage you to protect yourself through a password change. Potential areas of concern such as duplicate or weak passwords are also identified.

The cost of using 1Password is markedly different than cloud-based password lockers. Users must purchase clients for each platform they intend to use, costing more up front than a subscription service, but potentially saving money in the long term. 1Password for PC or Mac cost $49.99; the Mac-plus-PC bundle runs $69.99. Both the iOS app and Android apps are free with an in-app upgrade to the Pro feature set for $9.99.

My biggest concern with 1Password has to do with feature parity between the Mac and PC versions. Currently both platforms offer similar features, largely due to a massive update to the Windows version mere days before publication of this article. Previously, features such as secure sharing or Wi-Fi sync were nowhere to be found. AgileBits has made good on promises to bring these features to all platforms, but if you're primarily a PC user, the lag may be cause for concern. Regardless, 1Password is a strong password manager. With AgileBits' strong ties to the Apple community, this is particularly true for Mac and iOS users.

Dashlane

Dashlane toes the line between cloud service and local password manager in an attempt to answer every security concern. You can store your password database on Dashlane's servers and take advantage of synchronization across devices, or you can store your password vault locally and forgo synchronization. It's your choice.

If you store your password database in Dashlane's cloud, your master password remains with you only. Rather than storing a hash of the master password on its servers, Dashlane claims to use your password merely to encrypt and decrypt the data locally. For this reason your password database on the Web is read only, and changes can solely be made on a client.

Authentication is performed against devices that are registered with Dashlane through a two-step process, incorporating your master password and a device registration code sent via email. Two pricing tiers are offered for Dashlane users. A free account allows access to your passwords through a single device of your choice. Premium accounts, which cost $39.99 per year, let you synchronize your passwords across multiple devices, perform account backups, share more than five items, give you access to the read-only Web app, and entitle you to Dashlane's customer support.
Dashlane score

Dashlane will store your password database in the cloud, but your master password remains with you only. (Don't lose it!). Like other password managers, Dashlane will assess the strength of your password as you create it.

With Dashlane, retention of your master password is critical. The company states that it is unable to perform password recovery in the event of loss, a necessary side effect of its decision to not store a copy of your password in any form. Two-factor authentication is also supported through the use of Google Authenticator. Support for two-factor authentication must be enabled through the Windows or Mac client and can only be used on Internet-connected clients.

Dashlane’s team features allow you to securely share login information with other Dashlane users, providing them with an appropriate level of access to the information. Shared items can be provided with limited rights, which restrict the ability to change permissions or reshare an item, or with full rights to the data. Dashlane also offers the ability to designate emergency contacts, making it easy to allow family or co-workers access to critical accounts or information in the event of an emergency. The data shared with an emergency contact can be fine-tuned in order to only provide certain information to specific contacts.

Because Dashlane attempts to be a hybrid of a cloud-based and local password manager, it isn't as full featured as other cloud offerings, and it may not win over customers fearful of cloud services. However, Dashlane has been able to accomplish something truly remarkable through no small amount of ingenuity and attention to security precautions. Before you dismiss Dashlane because it's a cloud-based service, take a look at the company's security whitepaper, which details the concepts and security practices it has implemented.

KeePass

A mature open source project (GNU GPL version 2), KeePass is a free password management solution for Windows, OS X, or Linux, running natively on Windows and requiring Mono for the other platforms. Many of the benefits of open source software are prevalent in KeePass, including ports to other client operating systems and a robust plug-in ecosystem. With the extensibility offered by plug-ins for KeePass, you can change the encryption algorithm, automate logins through your browser, integrate an on-screen keyboard, or even create scripts you can run against KeePass.

KeePass was designed to store a local copy of the password vault. Cloud backup and support for synchronization across multiple devices are obtained through plug-ins that work with the likes of Dropbox, Google Docs, and Microsoft OneDrive. A side benefit of a local password database such as KeyPass is the ability for multiple users to share a database or for one user to keep multiple databases, sharing some and keeping others private.

KeePass master

With KeePass, you can lock your password vault using a combination of password, key file, and Windows authentication.

Mobile support for KeePass is a little more obtuse than some of the commercial options. Ports are available for iOS, Android, and Windows Phone, but the big question becomes synchronization support. Not all mobile ports support cloud synchronization, and those that do support only a subset of the cloud options. Some mobile KeePass clients carry a cost, though most are in the $1 to $2 range.

If you're more concerned about the security of your password vault than mobile clients and device synchronization, you'll be pleased to know that KeePass supports multiple authentication methods by default. KeePass database files can be locked by a combination of password, key file, and Windows user account. With a key file stored on removable media such as a USB thumb drive, two-factor authentication can be used to secure access to your critical passwords.

The biggest downside to KeePass is complexity. Getting all of the advanced functionality offered by the competition will require quite a bit of research, setup, and maintenance. While KeePass is a great solution for fans of open source, maximum flexibility, and free software, it is certainly not as straightforward as some of the cloud-based services listed here.

LastPass
LastPass may be the most popular password manager in this review, due to a rich set of features, support for a wide range of mobile platforms, and straightforward licensing, not to mention aggressive marketing. Unlike KeePass, LastPass is decidedly cloud-centric, using its own cloud service to store user information and synchronize data.

A recent LastPass security notice underscores one drawback of a cloud-based password manager: It makes a tempting target for hackers. Although no user accounts were accessed and no vault data was taken, attackers did make away with account email addresses and other data that could be used in targeted attacks. Bottom line: LastPass users should change their master passwords. Brian Krebs' post on the LastPass breach provides a concise explanation of the risks.

LastPass offers a free and premium pricing tier for consumers, with the premium service costing $1 per month. Users of the free edition get many of the basics you'd expect from a cloud-based service, including plug-in support for multiple browsers, anywhere access, and even support for multifactor authentication using Google Authenticator on an Android or iOS device or Microsoft Authenticator on Windows Phone. Mobile device support requires a premium account but includes support for iOS, Android, BlackBerry, and Windows Phone. Even some mobile browsers such as Dolphin and Firefox Mobile work with LastPass Premium to automate username and password entry. Finally, premium users get access to the LastPass support team, rather than being relegated to the user forums.

LastPass vault
LastPass offers handy functionality for sharing accounts with friends and family. The free service allows you to selectively share account login information with other LastPass users, allowing them to authenticate to individual Web applications using your information, without giving them direct access to your passwords. Premium account subscribers get access to a Family Folder, a feature that lets you specify exactly which login information to share with up to five other LastPass users.

Desktop support for LastPass is somewhat confusing. Downloading the basic installer for Windows provides browser plug-ins, an import tool (for migrating from another password vault or spreadsheet), and a shortcut to the LastPass Web app. Premium subscribers also have access to LastPass for applications, which provides increased utility by allowing you to automatically log into desktop applications such as Skype or a corporate VPN client.

LastPass supports several forms of two-factor authentication. I've already mentioned that both Microsoft Authenticator and Google Authenticator are supported with free accounts, providing simple integration using a mobile device. Premium accounts gain support for Yubikey, a USB hardware authentication device, and Sesame, a software authentication tool run from a USB storage device.

If you need simple password management in a Web app, you can't go wrong with a free LastPass account. For more granular credential sharing and mobile device support, LastPass premium will be the best $1 you spend each month.

PasswordBox

PasswordBox bears a number of similarities to Dashlane. Master passwords are neither stored nor transmitted, meaning that password data is secured throughout the process, and password resets are technically impossible. PasswordBox even takes extra steps to ensure the security of your information in other ways, such as PCI-compliant data centers and providing the ability to send the company encrypted email using the PGP key published on its website.

PasswordBox is currently missing some of the features available in Dashlane, such as two-factor authentication, but both two-factor and fingerprint-based authentication are reportedly coming soon. You can read about the security measures PasswordBox uses to safeguard password data in the company's security whitepaper.

PasswordBox does not use stand-alone client programs on Windows and Mac, opting instead for browser plug-ins (Chrome, Firefox, and Internet Explorer), but mobile apps are available for both iOS and Android. Another minor oddity: PasswordBox doesn't offer a Web app to view or edit passwords or manage your account -- everything is handled via mobile app or browser plug-in.
PasswordBox

PasswordBox stores your passwords on its servers, but they're never decrypted there. Passwords can only be viewed and edited using the browser plug-in or mobile client.

PasswordBox is priced competitively with the other cloud-based password managers. Free accounts support up to 25 stored passwords, including synchronization and full sharing capabilities. Premium accounts cost $12 per year and give you unlimited password storage. Referring five friends nets you a premium account for life.

PasswordBox allows users (free or premium) to share saved login information seamlessly between accounts, even without the passwords being visible. Shared log-ins persist even through password changes, and they can be revoked at any time. An interesting and unique feature of PasswordBox is the Legacy Locker, which allows you to designate one or more responsible parties who get access to your account information in the event of your death. Account transfers using Legacy Locker are not performed until a death certificate is provided and validated.

PasswordBox is now part of the Intel Security Family, meaning its future is in a state of flux. For now Intel Security is offering free premium subscriptions to both new and existing users.

SplashID Safe

SplashID has been in the password manager business for years. Its product, SplashID Safe, has been particularly popular on mobile devices. Currently SplashID Safe supports access through the Web and client apps for Windows desktop, Windows, Mac, iOS, Android, BlackBerry 10, and Windows Phone.

Where other password managers are either local or cloud-based, SplashID Safe supports either option. SplashID has simplified its licensing structure somewhat in version 8. A basic SplashID account is free, but limits you to one device and doesn’t allow sharing or backup. A SpashID Pro account allows you to synchronize your password vault for $1.99 per month or $19.99 per year. SplashID Pro supports unlimited devices, synchronization over the Internet or Wi-Fi, sharing, and automated backup. It also comes with customer support.

For an additional $5 per user per month, families or businesses can leverage SplashID Safe Teams edition, which adds an admin panel that allows you to control who has access to each record, either by assigning a record to an individual user or a group of users.

SplashID Safe has at least one feature we wish all the cloud-based services would implement: the ability to configure a login as local only, giving you the ability to prevent your most sensitive data from being stored on the Internet. The idea is that if you have certain login information or other sensitive data you don't trust to the Internet, you can prevent this information from being uploaded to SplashID's servers.

SplashID Safe supports two methods of sharing login information. When sharing with a user who has a SplashID cloud account, the login information is imported directly into their account. Users without a SplashID cloud account will receive an email containing a link to securely retrieve the information. Links to shared information are secured with a password (which can be included in the email or shared using another method), are valid for only 24 hours, and expire after the first use.

Two-factor support in SplashID only provides an extra layer of security when registering a new device (not on each login), requiring you to enter a six-digit code sent via email. While a registered device paired with a password technically meets the definition of two-factor authentication (something you have and something you know), it's not quite up to par with services offering support for Google Authenticator or other two-factor methods. SplashID Safe offers a pattern unlock feature as an alternative to a master password, but I found this feature to be somewhat inconsistent.
Other contenders

It's always nice when a security product is backed by a brand synonymous with computer security, and Symantec's Norton Identity Safe certainly has that factor in its favor. Identity Safe has another plus: It's completely free. You can choose from a number of free password managers, but none are cloud services operated by a software vendor with a level of trust built up over decades. Norton Identity Safe used to be part of a Norton security suite, but it's now a stand-alone service with a Web front end and clients for Windows, iOS, and Android.

RoboForm is a popular password manager and form filler, but it falls short of the leading contenders on a few counts. Though it offers synchronization across multiple platforms, there is no Web app, two-factor authentication, or sharing capability. Individual RoboForm desktop licenses can be purchased outright for Mac or PC at a price of $29.95, and a Windows portable version for USB storage is available for $39.95. RoboForm also offers subscription-based licensing for $19.95 per year, which provides synchronization and access through mobile apps on iOS, Android, Windows 8, and Windows Phone.

KeePass isn't the only open source password manager. There's also Password Safe, currently available for Windows in both installable and portable versions, and for Linux in a beta version. Password Safe is not nearly as feature-rich or mature as KeePass, and I'd be hard-pressed to give you a reason to use it over its big brother. That said, Password Safe is a viable alternative, and if all you need is a local password manager, the decision may come down to which program you find easier to use. The result may be Password Safe.

My1Login has both a free version, supported through advertisements and affiliate links to partner sites, and a pro version, which eliminates the ads and affiliate links for $2 per month. My1Login offers features commonly found in the other contenders such as secure sharing and strong password generation. The problem with My1Login is that the entire service is Web-based, with mobile support coming through the mobile Web app only. While My1Login is enthusiastic about the minimal setup requirements due to the lack of client applications, I find this method to be more difficult to use in the long term.

Keeper Backup is full-featured password manager supporting multiple client platforms, including Mac, Windows, iOS, Android, and Windows Phone. Security features offered by Keeper Backup include two-factor authentication and secure sharing. Keeper offers three pricing tiers, starting with a free edition that supports one device, no sharing, and a limited amount of data. Keeper Backup provides unlimited storage, access to the Keeper Web app, secure sharing, and access to the support team for $9.99 per year. Backup Unlimited adds support for synchronization across devices for a heftier $29.99 per year.

Trend Micro's DirectPass has a free option that supports only five passwords. Trend Micro's subscription service, which costs $14.95 for one year or $24.95 for two years, supports an unlimited number of passwords and devices. Desktop clients are available for both PC and Mac, and mobile clients are available for iOS and Android. While there's nothing wrong with DirectPass, it doesn't match other competitors in features or polish.

Cisco to make $10 billion investment in China

Cisco plans to invest US$10 billion in China, although its sales in the country are slumping due in part to persistent security concerns surrounding U.S. technology.

The investment marks a “new chapter” for the company, and it includes agreements with the Chinese government to expand in areas including research, and job creation, Cisco said on Wednesday.

The $10 billion investment will be made over several years, and will help spur technology innovation in the country, Cisco said, without further elaborating. It called the move a “renewed commitment” suggesting that the investment would be added on top of its existing operational expenses in China. Cisco could not be immediately reached for comment.

As part of the investment, the company has signed agreements with China’s National Development and Reform Commission, a high-level government agency, and with an association connected to the Ministry of Education.

Cisco has been in the Chinese market for over two decades supplying networking equipment, including what’s used in the country’s Internet infrastructure. But its business in the country has struggled in recent years due to “geopolitical challenges”, according to the company.

Following leaks about the U.S.’s secret surveillance programs, China has made cybersecurity a priority. As a result, the country is considering stricter regulations that could push U.S. tech firms out of the market.

In Cisco’s case, it also had to contend with competition from Huawei Technologies and ZTE, two Chinese companies that have become major players in the networking sector and are moving into enterprise services.

But even as China focuses more on cybersecurity, Cisco said on Wednesday it’s committed to the market. The company announced the investment as both its outgoing CEO John Chambers and incoming CEO Chuck Robbins met Chinese government officials.

Cisco will continue to “work closely” with the Chinese government and its partners to better meet demands for the market, Cisco’s head of the Greater China Owen Chan, said in a statement.

Back in 2007, Cisco made another huge investment in the country that reached $16 billion. Most of the money was geared toward doubling its manufacturing.

The market opportunity in China is huge. The country has over 600 million Internet users, and there’s a growing need for more data centers, and faster networking infrastructure.

4 new access points deliver super-fast Wi-Fi

Linksys, Xclaim, Amped and ZyXel bring 802.11ac to SMB, enterprise markets.
access points fast wifi 1

Access points put to the test
We put four new access points to the test, from Linksys, Xclaim, Amped and ZyXel, using the same test-bed and methods as our last review. The Linksys LAPAC1750PRO performed best in the throughput tests and was a feature-rich product. The Amped Wireless AP was a close second in the speed tests and is a solid business-class access point. The Xclaim unit did well given it’s only a two stream (2x2) AP. The ZyXEL unit was last in throughput, but has a number of advanced features in the areas of configuration, management and security. (Read our full review.)

Amped Wireless APR175P
Targeted at the SMB market, the Amped Wireless APR175P bills itself as a high-power long range access point. Priced at $299.99, it is a dual-band three stream (3x3) 802.11ac AP, offering theoretical data rates up to 1,300Mbps for 802.11ac. In our testing, the maximum throughput was 335.6Mbps. This is the only access point in the review that sports external antennas, which provides for either ceiling or wall mounting. In addition to the three external antenna, it has six high power amplifiers and six wireless reception (low noise) amplifiers.

This access point is the only one in the review that supports a router mode. Additionally, it's the only one that specifically touts being long range and high-power at 500mW output. The built-in controller functionality supports the central management of up to seven access points. This access point allows you to create up to 32 SSIDs with VLAN support. This unit offers load balancing and an intrusion detection system (when in router mode). It also offers an internal RADIUS server supporting the PEAP and TLS methods of 802.1X authentication, enabling the use of the Enterprise mode of WPA2 security.

Linksys LAPAC1750PRO
The Linksys LAPAC1750PRO is targeted towards small and midsized businesses (SMBs) and is priced at $499.99. It is a dual-band three stream (3x3) 802.11ac AP, offering theoretical data rates up to 1,300Mbps for 802.11ac. In our testing, it maxxed out at 436.3Mbps. Inside the unit are three 4.4 dBi internal antennas for 2.4GHz and three 5.2 dBi gain antennas for 5GHz. On the back of the unit are two PoE Gigabit Ethernet ports (one with PoE), AC power jack, and a small reset button.
access points fast wifi 5

When using the Cluster feature, you can centrally manage up to 16 access points using the built-in controller functionality. Once you enable the clustering feature on one access point, others access points will join that cluster. You can centrally change the configuration settings of the cluster via any access point in the cluster. This unit supports the use of up to 16 SSIDs with VLAN support. In addition to traditional AP mode, you can use the unit in WDS and workgroup bridge modes. Its Captive Portal feature supports guest, local, and external RADIUS authentication and can do URL redirection upon authentication. This access point supports rogue AP detection, band steering, and beamforming. It also has basic load balancing functionality.

Xclaim Xi-3
The Xclaim Xi-3 from Ruckus Wireless retails for $199 and is targeted towards small businesses and small office/home office (SOHO) environments and to the non-IT users. It's the only two stream (2x2) AP in this review, thus naturally offering lower maximum data rates than the other APs: up to 867Mbps for 802.11ac. It hit 315.7 Mbps in our testing. The Xclaim unit has a look and feel between a consumer router and a business access point. On the back/bottom of the access point you'll find one PoE LAN port, a secondary Ethernet port, small reset button, and an AC power jack. On the back/bottom of the Xclaim AP are the typical AP ports and buttons.

Unlike most other business-class products, this unit is primarily designed to be setup and managed via a mobile app, called Harmony for Xclaim. This unit only provides the traditional AP mode; no WDS or wireless bridging supported. The built-in controller functionality offers central management via the mobile app with a recommended maximum of 10 APs. You can create up to four SSIDs per access point with VLAN support. As far as advanced features, the unit has band steering, an enhanced QoS functionality called automatic traffic prioritization, and a feature called airtime fairness to help curve the negative impact from older or slower devices.

ZyXEL WAC6503D-S
The ZyXel WAC6503D-S, priced at $899, is targeted towards the enterprise-level market. It is a three stream (3x3) 802.11ac AP and offers theoretical data rates up to 1,300Mbps for 802.11ac. However, in our testing, it only reached 232.6Mbps. The unit is designed for ceiling mounting, with the smoke detector look and feel.

On the front/top of the AP you'll find seven LED status lights. On the back/bottom you'll find three Ethernet ports: PoE port for uplink, secondary LAN port, and one for console access. You'll find a small reset button and AC power jack as well.

A separate NXC Series WLAN controller is required for full central management capabilities. In addition to the regular AP mode, this access point supports WDS and a monitor mode for rogue access point detection. This ZyXEL AP supports up to 16 SSIDs with VLAN support. It has load balancing and band steering functionality. This AP series has what the company calls its Smart Antenna technology, which dynamically chooses the best of more than 700 antenna patterns to use for transmitting to individual clients

Included free of charge is the ZyXEL Wireless Optimizer (ZWO) software, which is a mapped-based Wi-Fi simulation, planning, and surveying tool.

The experts weigh in on their top picks for protecting enterprise networks.

Security tools
Network World asked security pros to name their No. 1, must-have, go-to security tool. We received responses from industry analysts, enterprise security practitioners, academics, and members of industry associations. Many of the experts we interviewed pointed out that there is no silver bullet when it comes to security, so your best bet is a defense in depth strategy that combines as many of these approaches as possible. Read the full story.

SysInternals and Windows GodMode
Ron Woerner, director of CyberSecurity Studies at Bellevue University: "There are certain things all network, IT, and security professionals should have in their toolbag. The most important is knowledge; i.e., where to learn more about a particular topic, technique, or tool. It’s impossible to know everything; so focus on where to get quality instruction and information."

Woerner recommends two websites: www.howtogeek.com and blogs.msdn.com/ for reference; and two toolkits: SysInternals and Windows GodMode. The former is a grouping of simple Windows tools and the latter is administration applications already available in the Control Panel.

Microsoft EMET
Yier Jin, assistant professor of computer science and electrical engineering at the University of Central Florida, says knowledge is the key. "I would say cybersecurity awareness is the one, best tool. Many breaches are caused by internal workers who lack cybersecurity awareness and; therefore, click links from spam email, which often initiates the breach. For tools, I recommend Microsoft Enhanced Mitigation Emergency Toolkit (EMET), an excellent toolkit that every company should have."

Secure@Source, Q-Radar, ArcSight, Splunk
Jeff Northrop, CTO at International Association of Privacy Professionals, uses the term data security intelligence to describe tools that help IT understand their data landscape. "Currently, we have business intelligence tools, data integration tools, data discovery tools, data encryption tools, compliance tools, and SIEM tools. All require an understanding of what data is collected; where it's located; how it's structured, categorized, and used. Most vendors operate in one or two of these areas; but a few companies have recognized a need for better information on the data they're responsible for protecting; extending their products to meet this need." Northrop lists Informatica’s Secure@Source; IBM’s Q-Radar, HP’s ArcSight, and Splunk.

Insider threat protection
Mike Papay, vice president and CISO at Northrop Grumman says, "In the context of destructive malware and insider-enabled data loss, businesses should invest in security tools that protect from the inside out. Similar to a broken windows policing strategy, security tools that can baseline, and then detect and alert on anomalies in network and client behavior helps businesses mitigate problem-activity early in the threat cycle.”
Privileged identity management

Privileged identity management
"I recommend Privileged Identity Management (PIM) tools that control the administrative password and, in some cases, shared business passwords and credentials," says Andras Cser, vice president and principal security/risk analyst at Forrester. "These tools are absolutely critical to ent data breaches by making always-on system administrator access to on-premises and cloud workloads a thing of the past. PIM tools check out and change passwords for critical workloads, which makes attackers' snooped administrator and root passwords worthless. Also, PIM (generally) enforces close monitoring and recording of all programmatic and/or human administrative access to machines."

Patch management
"There are three tools that all companies should have," says Gary Hayslip, deputy director and CISO for the City of San Diego, "patch management, data backup, and full disk encryption. These tools provide the basic cyber-hygiene foundation, which enables companies to continue to grow safely and respond to incidents. Then, as the revenue stream increases, they can add more security controls to the organization. If I had to choose just one, I'd say patch management. Having a patch management solution in place reduces risk exposure to the organization by keeping its IT assets up-to-date, which makes it harder for the bad guys. However, there's no guarantee that any, one solution will resolve all issues."

Cyphort
David Giambruno, senior vice president and CIO at Tribune Media, suggests that enterprises should move toward the concept of a software defined data center. "We're using VMware’s solution stack for its micro-segmentation capabilities—summarized as security at the element layer," he says. "Historically, this was incredibly challenging with hardware but, in the software world—where everything is a file—you can wrap everything with a security posture. Security follows wherever the element goes either internal or external. The audit-ability, operational automation, and visibility changes defensive capabilities." Giambruno deployed Cyphort for its capabilities to see east/west traffic in the cloud.

Bluebox
"One interesting new area is using technology to provide a layer between the user and SaaS solutions, so the enterprise can manage authentication and encryption and hold its keys, while maintaining close-to-full functionality with the software as a service (SaaS) solution," says Dr. John D. Johnson, global security strategist and security architect for John Deere. "There are also new solutions for cloud file storage and sync (like Box) that add encryption, data loss protection, and granular reports." For BYOD, he recommends products that keep corporate data in a container and ent it from moving, such as Bluebox, which puts a flexible walled garden around certain data and apps, and applies corporate rules.

Endpoint detection and response
Neil MacDonald, vice president and distinguished analyst at Gartner, advises clients to first remove administrative rights from Windows users, then invest in an endpoint detection and response (EDR) solution that continuously monitors and analyzes the state of the endpoint for indications of compromise. MacDonald emphasizes that EDR solutions provide continuous visibility that, when combined with continuous analytics, can help enterprises shorten the time that an attack goes undetected "For server workloads, I’d replace anti-malware scanning with an application-control solution to ent the execution of all unauthorized code, which keeps the vast majority of malware off the system and, also, reinforces good operational and change management hygiene.

FireEye
Randy Marchany, IT security lab director & security officer at Virginia Tech, says the flaw with static perimeter defense is that most organizations focus on inbound traffic rather than outbound traffic. Continuous Monitoring , also known as Network Security Monitoring or Extrusion Detection, focuses on traffic and log analysis. He recommends the FireEye Malware Detection appliance, Netflow data (which provides invaluable information that determines if internal machines have been compromised), and tools such as ARGUS Software, SiLK , the System for Internet-Level Knowledge, a collection of traffic analysis tools developed by the CERT Network Situational Awareness Team, and/or the Bro network security analyzer.

Advanced security analytics
Johna Till Johnson, CEO at Nemertes Research, recommends Advanced Security Analytics (ASA), which provide real-time insight into—and, increasingly, proactive responses to—situations that indicate a potential breach, compromise, or vulnerability. ASA merges security event/incident management and monitoring (SEIM) with analytical capabilities often derived from Big Data technologies. It also includes forensics and Intrusion Detection Systems/Intrusion ention Systems. Johnson recommends tools from vendors such as Agiliance, Blue Coat, Damballa, FireEye, Guidance, HP ArcSight, IBM, Lastline, LogRhythm, McAfee/Intel, and Splunk.

Collaboration Tools
"My vote for security's best option is collaboration tools. Yes, we have plenty of silver bullets; what we really need are more tools that allow communication and collaboration for our distributed workforce. We need to capture tribal knowledge to make staff more effective. We need to invest in tools that make staff more agile," says Rick Holland, principal security/risk analyst at Forrester Research.

Threat Intelligence
Frank Kim, CISO at the SANS Institute, believes security capabilities that detect attackers and anomalous activity are even more important in the face of advanced threats which bypass traditional, entative mechanisms. As a result, threat intelligence and robust information sharing are key aspects of modern cyber defense. But it's also about advanced analytics and the ability to mine internal and external sources of data. Building a data science capability to intelligently analyze large amounts of information provides organizations with actionable information that allows security teams to respond more quickly.
