Defense-Enabled Applications

Date Added: Oct 2009

Some applications can be given increased resistance to malicious attack even though the environment in which they run is untrustworthy. The authors call any such application "Defense-enabled". This paper explains the principles behind defense enabling and the assumptions on which it depends. Ideally, one defends a computer system against malicious attack by identifying, in a security policy, what one wants to protect and then by implementing that protection in hardware and software. The implementation is called a Trusted Computing Base (TCB).
