Hi All, I have developed an application, which I believe can provide 100% security against various attacks.I can hear people laughing. Hmm.. The applications is called Execution Flow Control (EFC). Details of software can be found at http://203.197.88.14/efc
You are doing system call monitoring based on a program model, and killing programs which deviate, assuming I read the documentation correctly... A: You have false positives unless you generate this database through program analysis or some other technique. "Security" procedures which make systems less reliable are only rarely acceptable. B: This has been done, based on program analysis, traces, and a whole host of other techniques. Probably the best example based on program analysis is "Intrusion Detection via Static Analysis" David Wagner and Drew Dean: http://www.cs.berkeley.edu/~daw/papers/ids-oakland01.ps This is probably the nicest imply because their model does NOT have false positives, only false negatives. C: How to waltz through this "100%" protection: "Mimicry Attaks on Host-Based Intrusion Detection" David Wagner and Paolo Soto: http://www.cs.berkeley.edu/~daw/papers/mimicry.pdf -- Nicholas C.
