Embedded Application Whitelisting

Karamba XGuard Whitelisting:
Deterministically Prevents The Loading
Of Unsigned Executables

Application whitelisting is not a new idea in security, and in a confined application the “known good” list is a very effective security measure against dropper attacks.

Hackers looking to upload new scripts, binaries or libraries into memory during runtime will be blocked, as the whitelisting compares each executable with the contents of the authorized list.

Karamba's secret sauce is the automatic process to map and build this whitelist. In very large applications with thousands of executables, only an automatic and granular building of the whitelist is practical to protect the code.

Given the dynamic nature of the supply chain, Karamba XGuard Whitelisting has a built-in mechanism to allow external signed binaries from third-party suppliers as well as update diffs from the image authority.
