A computer chip, such as an System on chip (SOC), can receive firmware updates having two separate signatures; a first of the signatures is used to authenticate the firmware using a processor within the computer chip, and a second of the signatures is used by a controller, separate from the processor. A first key, used by the processor to authenticate the firmware, can be a boot key that is hardwired in the computer chip. A second key, used by the controller, can be a key that is provided to the controller at any time and is updatable. The controller can suspend the processor so that the controller can perform a first authentication of the firmware using the second signature and the second key. If the authentication is successful, the controller can release the processor, which then uses the first key and the first signature to perform a second authentication.

Client devices detect malware based on a ruleset received from a security server. To evaluate a current ruleset, an administrative client device initiates a ruleset evaluation of the malware detection ruleset. A security server partitions stored malware samples into a group of evaluation lists based on an evaluation policy. The security server then creates scanning nodes on an evaluation server according to the evaluation policy. The scanning nodes scan the malware samples of the evaluation lists using the rulesets and associate each malware sample with a rule of the ruleset based on the detections, if any. The security server analyzes the associations and optimizes the ruleset and stored malware samples. The security server sends the optimized ruleset to client devices such that they more efficiently detect malware samples.
