Fine-tuning

After you install the Host Intrusion Prevention software, McAfee recommends that you configure it to provide the greatest amount of security while not conflicting with day-to-day activities. The default policies in Host Intrusion Prevention fit the broadest set of customer environments and may meet your needs. To fine-tune policies to fit your particular setting, we recommend the following practices:

Carefully define your Host Intrusion Prevention security configuration. Evaluate who is responsible for configuring particular parts of the system and grant them appropriate access.

Change the default IPS Protection or Firewall Rules policies, which provide increasing levels of preset protection.

Modify severity levels of specific signatures. For example, when a signature is triggered by day-to-day work of users, adjust the severity level to a lower level. For more information, refer to Configuring the IPS Protection policy on page 38.

Configure notifications, which alert specific individuals when particular events occur. For example, a notification can be sent when an activity that triggers a High severity event occurs on a particular server. For more information, refer to Setting up notifications for events on page 123.
