The process to update the security agent is the same as installing the security agent. Depending on the method that you used to install the agent, you can perform the steps in Installing the security agent manually for Amazon EC2 instances.
If you use Method 1 - By using AWS Systems Manager, then you can update the security agent by using the Run command. Use the agent version to which you want to update.
If you use Method 2 - By using Linux Package Managers, you can use the scripts as specified in the Installing the security agent manually section. The scripts already include the latest agent release version. For information about recently released agent versions, see GuardDuty security agent for Amazon EC2 instances.
After you update the security agent, you can check the installation status by looking at the logs. For more information, see Validating GuardDuty security agent installation status.
