Data-Loss Prevention Software Takes Security Up A Notch

Vendors offer more options for protecting data throughout its travels. We'll put their claims to the test.

Time To Break Into The IT Budget
Data breach horror stories, regulatory pressure, and more options have created a hot market for DLP. This in turn has led to market churn as large players acquire the original thought leaders in the DLP arena. So it's not surprising that many organizations are sitting on the sidelines waiting to see how things shake out. Others are very interested in DLP but have unanswered questions. And for every company sitting on the sidelines, another has been forced to make the investment because of strict security or regulatory requirements. This Rolling Review will help organizations get unbiased information about the state of DLP as well as their options.

Each of the vendors in this Rolling Review claims to have (or soon will have) the ability to protect data at rest, in use, and in motion. Code Green, McAfee, RSA, Safend, Symantec, and Vericept have made commitments to participate in the testing, and at press time we were waiting on final approval from Websense to round out our group of participants.

To test enterprise DLP products, we'll unleash chaos on the fictional legal firm we built for our virtual desktop infrastructure Rolling Review, Bits and Bytes Legal Services. This fictional legal startup has a staff of about 100 in four offices across the country and shares high volumes of data on a variety of pipes. Using a combination of proprietary intellectual property and private customer information, we'll simulate various attacks to see how well each product can detect, report, and remediate each one.

It's impossible to protect your data with 100% certainty, of course, but in reality, DLP is often about making your security capabilities just strong enough to send hackers on to the next potential victim. Simulations will test how well the vendor can protect against data loss on handheld devices and PCs, prevent intellectual property leaks via IM, or prevent data leaks via e-mail, FTP, USB thumb drives, prohibited printing, and screen capture.

The Essentials
THREE MUST-HAVES
FOR EFFECTIVE DLP
1. Communication Lockdown Your data can be pickpocketed from any number of communication modes. Make sure your DLP system has an answer for each contingency and can protect you both at the endpoint and in the network cloud.
2. Data Discovery Done Well Your solution's data discovery capabilities must be robust enough to crawl all file systems, devices, and structured databases necessary to reveal points of exposure.
3. Reporting Look for capabilities that connect a potential data breach to a violation of a regulation, industry standard, or custom business rule.
Measuring the ROI of a large security investment in today's budget-strapped environment is critical, so we'll pay particular attention to the reporting capabilities of each product.

While some of the marketing hype tries to portray internal employees as evil security threats, our investigations and interviews with DLP vendors reveal this isn't the case. More often than not, a data leak that originates internally is the result of an accident or a broken business process. Unfortunately, accidental data leaks are just as damaging as intentional ones, so products also will be evaluated on whether they can determine if a leak broke an internal business rule or government regulation, such as PCI or HIPAA.

We'll also play close attention to how easy it is to deploy and manage, because few companies can stomach adding staff or a boondoggle of a professional services engagement tacked onto the final bill.

When deploying DLP, one of the biggest challenges that organizations encounter is knowing where all their confidential data resides. Given how important data discovery capabilities are to DLP tools, we'll closely scrutinize each vendor's ability to accurately classify where critical data resides. As a result, each vendor must have a methodology for detecting, for example, files or databases that contain unencrypted Social Security numbers or credit card numbers.

At the conclusion of this Rolling Review, we'll report our big-picture findings, with an emphasis on pointing out any gotchas that system administrators will encounter as they deploy these leading solutions, or others, in real-world implementations.

Rolling Review: DATA-LOSS PREVENTION
Business value An ounce of loss prevention can be worth thousands of dollars of remediation and lost corporate reputation. We'll test DLP options' ability to detect, report, and remediate trouble on handheld devices and PCs.

Rolling Review participants: McAfee, RSA, Safend, Symantec, and Vericept

Published: 2015-02-27
The seg_write_packet function in libavformat/segment.c in ffmpeg 2.1.4 and earlier does not free the correct memory location, which allows remote attackers to cause a denial of service ("invalid memory handler") and possibly execute arbitrary code via a crafted video that triggers a use after free.

CVE-2014-9682
Published: 2015-02-27
The dns-sync module before 0.1.1 for node.js allows context-dependent attackers to execute arbitrary commands via shell metacharacters in the first argument to the resolve API function.

CVE-2015-0655
Published: 2015-02-27
Cross-site scripting (XSS) vulnerability in Unified Web Interaction Manager in Cisco Unified Web and E-Mail Interaction Manager allows remote attackers to inject arbitrary web script or HTML via vectors related to a POST request, aka Bug ID CSCus74184.

CVE-2015-0884
Published: 2015-02-27
Unquoted Windows search path vulnerability in Toshiba Bluetooth Stack for Windows before 9.10.32(T) and Service Station before 2.2.14 allows local users to gain privileges via a Trojan horse application with a name composed of an initial substring of a path that contains a space character.
