I know that the fnord preprocessor is depreciated, but has anybody trie= d a converted fnord preprocessor for snort-inline? While tools like ADmuta= te try to defeat IDS and in this case IPS by changing the NOP sled typical= ly 0x90 to something that is equivalent and then encrypting the payload. = The NOP sled would still have to be unencrypted and we could alert and drop= on this. What do you guy's think, If I adapted it for snort-inline would = you use it. Does anybody know if it causes high false positives? Regards, Will= |
