In this chapter, you saw that you can configure global sensing, which affects IDS sensing parameters that are not specific to a signature, by defining internal networks and IP reassembly settings. You can tune signatures to meet your IDS requirements or create new custom signatures. To access signatures, you need to navigate to the corresponding signature group . Then, you can configure the signature with specific parameters and response actions. You can configure signature filters and filter exceptions to reduce false positives and to limit reported events.
