Firepower Preprocessor Rules, Security Intelligence filtering, SSL inspection, user identification, and some decoding and preprocessing occur before access control rules evaluate If it is a pass rule, it ignores the traffic. Introduction to Application Layer Preprocessors Application layer protocols can represent the same data in a variety of ways. Before packets are sent to preprocessors, the The following topics describe how to manage common characteristics of rules in various policies on the Firepower Management Center: Requirements and Prerequisites for Rule Management Introduction Intrusion Rule Tuning Basics You can use the Rules page in an intrusion policy to configure rule states and other settings for shared object rules, standard text rules, and preprocessor rules. If the Modbus or DNP3 preprocessor is disabled, and you enable and deploy an intrusion rule that requires one of these preprocessors, the system automatically uses the required preprocessor, with The Modbus preprocessor detects anomalies in Modbus traffic and decodes the Modbus protocol for processing by the rules engine, which uses Modbus keywords to access certain protocol fields. To help you build conditions, you can match traffic using various system-provided and custom configurations, including realms, ISE attributes, Advanced transport and network preprocessor settings apply globally to all networks, zones, and VLANs where you deploy your access control policy. What to do next If you want to generate events and, in an inline deployment, drop offending packets, enable Back Orifice Detection rules 105:1, Intrusion Rule Tuning Basics You can use the Rules page in an intrusion policy to configure rule states and other settings for shared object rules, standard text rules, and preprocessor rules. The Modbus preprocessor detects anomalies in Modbus traffic and decodes the Modbus protocol for processing by the rules engine, which uses Modbus keywords to access certain protocol Intrusion Rule Tuning Basics You can use the Rules page in an intrusion policy to configure rule states and other settings for shared object rules, standard text rules, and preprocessor rules. Change the access control policy’s default network analysis policy, which governs many preprocessing options. Configure The Firepower System provides two types of intrusion rules: shared object rules and standard text rules.
