Concluding Thoughts

This chapter has presented techniques for using psad to aggressively respond to malicious traffic. At several points, the arguments were tempered with recommendations for minimizing the potentially damaging effects of allowing any piece of software to respond to attacks, since this allows the potential for false positives and even the possibility that an attacker may attempt to turn an active response mechanism against the target. To combat these damaging effects, psad offers the ability to respond only to attacks that are delivered over established TCP connections; more on this topic will be presented in Chapter 11.
