1. There are two specific situations in which you will require the software license for purchased software:
   1. Updates
      1. Examples:
         1. Anti-Virus Software
            1. Malwarebytes
         2. Vulnerability Scanners
            1. Nessus
      2. When software is updated, the software requires a current license. This is renewed yearly with most providers.
      3. When updating, be sure to update the engine and the definitions if you are doing it manually.
      4. Otherwise, set the software to automatically update at periodic intervals.
   2. Incident Response
      1. When gathering data in response to a security incident, you might need to locate licenses for software, client connections, and hardware.
      2. Example:
         1. Client Access Licenses (CALs) used to access a Windows Server.
2. License compliance violation can have legal ramifications, and the software itself often provides reduced integrity and availability.
