A Logical Approach to Computer Security: Today's virus scanners are easy to fool. 'Malware writers obfuscate their code so that a signature that works today won't work tomorrow for what's essentially the same virus,' says Professor Sanjit Seshia of UC Berkeley. So he and collaborators have developed programs that analyze the semantics of code to separate malware from benign payloads. 'We're trying to develop a more behavioral definition of what it means to be malicious,' he says. 'Perhaps it deletes files on your hard drive or duplicates itself and emails copies to everyone in your address book.' Although technically 'undecidable', the professor claims that 'a good encoding of the problem enables the algorithm to run reasonably fast so we can think of eventually putting it into commercial tools.'
This document explains what you see in firewall logs, especially what port numbers means. You can use this information to help figure out what hackers are up to. This document is intended for both security-experts maintaining corporate firewalls as well as home users of personal firewalls."
