We've already learned that using flowbits allows us to make Snort rules work as a group. In this lab, we are going to look at different, and a.
Hi, I've just started using snort and I can't get it working. But now I'm trying to use a dynamic rule like the following: activate tcp $HOME_NET. For example, the previous rule will trigger on a single exploit packet such as most Snort rules. However, this rule then calls its dynamic partner to log the next Is it possible to create Snort activate/dynamic rules without voiding your support I have no problems creating basic alert and drop rules, like shown on the page .
