What is a best practice when configuring an Intrusion Prevention rule?

Keeping Intrusion Prevention rules in Detect mode until configuration is complete is a widely recognized best practice. This approach allows administrators to evaluate how the rules perform and the impact they may have on the system before enforcement. By using Detect mode, security personnel can monitor and review incidents without the risk of unintended service disruption or blocking legitimate traffic that might be wrongly flagged as malicious.

Once the rules are thoroughly tested and adjusted as needed, they can be transitioned into Prevent mode to actively stop any recognized threats. This strategy minimizes potential negative consequences during the initial configuration phase and ensures that the rules in use will effectively protect the environment without causing operational issues.
