Lumension application control review

Lumension Application Control is a strong whitelisting solution with broad file coverage, excellent reporting, and a complete set of Windows file definitions that can be used to spot potentially troublesome changes to system files. Its one noteworthy shortcoming is the inability to create whitelisting rules based on the digital signatures of application publishers.

Lumension, which is the product of the marriage of PatchLink and SecureWave, is the parent of several security components and modules, including Application Control, device control, data protection, vulnerability assessment, patching, and antivirus.

Application Control is essentially the latest incarnation of SecureWave's Sanctuary, an application whitelisting product that has been on the market for more than six years. Application Control can be purchased separately, but it is intended to be a primary part of the Lumension Endpoint Protection solution, which includes Lumension AntiVirus, or the Lumension Endpoint Security Solution Pack, which includes Lumension Device Control. Application Control and Device Control share the same management console.

The server side management console, called Lumension Endpoint Security Management, serves multiple components, so it's inherently a bit busier than its counterparts in whitelisting-only products. However, Lumension allows customers to use as many management servers as they need, without paying any server licences, a key advantage when trying to scale out an enterprise deployment or address performance or management issues.

Lumension, like SignaCert, comes with a complete set of standard file definitions (SFDs) for Windows 2000 to Windows 7 operating systems, prescanned and prehashed. These "gold" definitions are useful for noting deviations from the Microsoft defaults. Like all of the competitors in this roundup, Lumension can scan one or more existing computers to automatically generate whitelist execution rules, using the Scan Explorer feature.

Unlike most of the other competitors, Lumension can create whitelisting rules for all file types, although it defaults to executables only. The Exe Explorer feature will reveal individual files and their attributes found during the scan or already stored in the database. Files are identified by the normal file attributes (such as name or size) and SHA-1 hashes. Additionally, Lumension allows you to define path rules (allow only) and trusted users who can run anything (called Local Authorisation). Unfortunately, Lumension does not support whitelisting using publisher digital signatures, which is a significant omission in an otherwise very good product.

Identified files are then collected into one or more file groups, custom or predefined, for example, 16-bit, Accessories, Boot files, Logon files, Windows Common, or a trust but watch lists. File groups can be further subdivided. You could have, say, a collective group called Adobe that covers all Adobe files and subgroups for each of Adobe's various products, such as Adobe Reader and Adobe AIR. Lumension's Database Explorer lets the administrator view the various file groups and add identified files screen image.

Users, computers, and groups can be imported from the local Windows SAM (Security Accounts Manager) database, Active Directory, or Novell's eDirectory (Lumension and SignaCert are the only products in this review to integrate with eDirectory), and then linked to one or more file groups, along with whether that particular file group can be authorized (allowed to run) or unauthorized (prevent execution). Any file or file group not explicitly marked as Authorised is considered unauthorised. Like Bit9's Parity, Lumension can send an alert if a particular unauthorised executable becomes popular with too many users too fast. Called "Spread Check" in Lumension, this feature is designed to contain malware outbreaks.

Dialog messages are customisable. Users and administrators can quickly deny all unauthorised applications, modules (Visual Basic), and scripts (JavaScript and VBScript only) in an emergency. Each managed computer checks in for a new policy at every boot-up, and if the user is offline and unable to connect to the network, an admin can provide a new set of permissions (execute or not execute) that can be manually imported.

While the Report menu option shows system status information, such as when the client's policy was last updated or which server the client got its policy from, queries are both numerous and extremely flexible in Lumension's Log Explorer. Log Explorer shows whitelisting events and provides a good number of "query templates" that are useful in pulling needed information out of the log file. Each built-in query can easily be edited by clicking and choosing various fields of data, as well as dates, conditions, schedules, and formats (XML, CSV, HTLM). Plus, you can right click any event and turn it into a blacklisted or whitelisted file belonging to one or more file groups screen image.
