Recurring Rule Update Imports

L : Protection
ICENSE
As new vulnerabilities become known, the Sourcefire Vulnerability Research
Team (VRT) releases intrusion rule updates. Rule updates provide new and
updated intrusion rules and preprocessor rules, modified states for existing rules,
and modified default intrusion policy settings. Rule updates may also delete rules
and provide new rule categories and system variables.
If you plan to perform intrusion detection and prevention in your deployment,
Sourcefire recommends that you Enable Recurring Rule Update Imports.
You can specify the Import Frequency, as well as configure the system to perform
an intrusion Policy Reapply after each rule update. To perform a rule update as part
of the initial configuration process, select Install Now.
IMPORTANT! Rule updates may contain new binaries. Make sure your process
for downloading and installing rule updates complies with your security policies.
In addition, rule updates may be large, so make sure to import rules during
periods of low network use.
