Understanding Preventive Maintenance
The following actions will help you maintain your sensor:
•
Back up a good configuration. If your current configuration becomes unusable, you can replace it
with the backup version.
•
Save your backup configuration to a remote system.
•
Always back up your configuration before you do a manual upgrade. If you have auto upgrades
configured, make sure you do periodic backups.
•
Create a service account.
A service account is needed for special debug situations directed by TAC.
Caution
You should carefully consider whether you want to create a service account. The service account
provides shell access to the system, which makes the system vulnerable. Analyze your situation to decide
if you want a service account existing on the system.
