OS Independent Run-Time System Integrity Services

Overview A majority of critical server vulnerabilities in 2003 and 2004 were memory based. Today's advanced viruses and worms attack software running in memory to circumvent operating system protections. Such attacks often disable intrusion detection systems in order to execute malicious payload. Malware can also make use of secrets stored in system memory to circumvent cryptographic security measures. An isolated execution environment contained within the system can provide substantial resiliency against such attacks in an OS independent fashion. This paper describes a firmware based approach that protects critical software agents from three classes of attacks, elimination, tamper and circumvention through the use of run-time integrity checking and unspoofable presence verification.
