Is an asset inventory in your company's future?

May 22, 2003 12:00 PM ET

Computerworld - Do you know where all the licensed (and unlicensed) copies of Visio 2000, Yahoo tool bar, Xupiter DLLs or Outlook Express are in your company's systems? Do you know who still has the Windows Messenger Service turned on? If not, it may be time for a hardware and software asset inventory.


There was a lot of buzz about asset inventory at last month's 2003 RSA Security conference in San Francisco. It was an emerging theme that came through for those who attended sessions on vulnerability management, patching, intrusion detection, security management, emergency response and selling security to senior management. You can't protect your information and the information infrastructure if you don't know what it contains. In other words, you must have an inventory of your assets.


That makes sense, so what's the issue here? There are plenty, according to Steve Crutchley, chief security officer and co-founder of 4FrontSecurity, an enterprise security services firm in Reston, Va. At the RSA conference, Crutchley discussed ways to make information security relevant for an organization's board of directors. "Many organizations I have counseled lack an effective asset inventory. Without an asset inventory, how are the systems and network engineering groups supposed to sift through security alerts and know which ones apply to them and which can be discarded?" he said.

Many organizations have attempted to collect and maintain effective inventories of their IT assets, including data centers and desktops, to support total cost of ownership (TCO) and activity-based costing (ABC) efforts in the 1990s. Generally, these initiatives failed because the effort required to build and maintain an asset inventory was far greater than expected. Since then, many asset inventory programs have fallen into disrepair (see story).


Blended threats raise the bar


The phenomenon known as "blended threats," whereby worms and Trojan horses use multiple propagation paths (see story), is ushering in a new generation of security products that contain the best of intrusion-detection system tools and the automated processing of vulnerability alerts from product manufacturers and the CERT Coordination Center.


These products fall into the new niche known as vulnerability management. They work by keeping tabs on the latest vulnerability alerts, cross-referencing them against your hardware and software and creating "hits" when the two intersect. These hits translate into tasks where a systems administrator or network engineer needs to install a patch, change a configuration or mitigate the new vulnerability by some other means.
