SI-04(13) Analyze Traffic and Event Patterns

Control

  1. Analyze communications traffic and event patterns for the system;
  2. Develop profiles representing common traffic and event patterns; and
  3. Use the traffic and event profiles in tuning system-monitoring devices.

Discussion

Identifying and understanding common communications traffic and event patterns help organizations provide useful information to system monitoring devices to more effectively identify suspicious or anomalous traffic and events when they occur. Such information can help reduce the number of false positives and false negatives during system monitoring.

Assessment Objective

    1. communications traffic for the system is analyzed;
    2. event patterns for the system are analyzed;
    1. profiles representing common traffic are developed;
    2. profiles representing event patterns are developed;
    1. traffic profiles are used in tuning system-monitoring devices;
    2. event profiles are used in tuning system-monitoring devices.

Assessment Method
