coretrace whitepaper: combating buffer overflows and rootkits

CONTENTS COMBATING BUFFER OVERFLOWS AND ROOTKITS CoreTrace Corporation 6500 River Place Blvd., Building II, Suite 105, Austin, TX 78730 512-592-4100 | [email protected] | www.coretrace.com Buffer overflow + rootkit is the #1 combo meal on the cybercrime menu— a buffer overflow provides the way in and a rootkit provides the way to stay in, and invite some friends in too—and while an endpoint won’t get fries with that, if it is not protected with Endpoint Security v2.0, it may get Trojans, keyloggers, backdoors, installation routines, network sniffers, etc., (do be concerned with what may be hiding in that etc.). The best part, and why this technique is so popular, is that an endpoint is not aware that it has ingested anything. Rootkits are a MacGyver-worthy mashup of Swiss Army knife + Hydra + The Invisible Man—the best defense is a good offense was never more apropos. Not only is it difficult to know that a rootkit has control of an endpoint, even if known, it is not easily removed. The key to not allowing a rootkit to establish itself in an endpoint, is to not allow a rootkit to establish itself in an endpoint— just say no. The only way to do that is with Endpoint Security v2.0.

DESCRIPTION

Whitepaper Abstract Some malware threats are simply nuisances, and then there are truly dangerous and malicious ones. In the latter category, buffer overflow attacks and rootkits are the favorites of professional hackers. Often they are used in tandem, with a buffer overflow providing the way in and a rootkit providing a highly stealthy way to stay in. This whitepaper explains these two threats and why traditional security approaches have been largely ineffective against them. Then the paper outlines how Endpoint Security 2.0 solutions using kernel-level application whitelisting can effectively neutralize the threats and provide greater peace of mind.
