A small cadre of vendors is set to release a new class of host-based security technologies that protect applications and processes running in memory.

While many enterprises are still adjusting to the concept of signatureless defenses such as intrusion prevention systems, Determina Inc., a startup founded by a group of security-industry veterans, and Immunix Inc., a top Linux security provider, are rolling out solutions designed to lock down server memory space and allow only explicitly permitted operations among applications and processes.

This tack represents a shift from the decades-old approach of detecting and stopping attacks in progress using signatures or pattern-recognition algorithms. Customers and security experts say the new tools signal a new direction for the industry at large.
