Keep your security up to date

To ensure maximum protection, there are two components that you must periodically update:

• Software updates: Updates to the Deep Security Agent and Deep Security Virtual Appliance software. See Update Deep Security software.
• Security updates: Updates to the security rules and malware patterns that Deep Security uses to identify potential threats. See Get and distribute security updates.

Both software updates and security updates need to be distributed to your agents and virtual appliances. The recommended way to retrieve and distribute the updates is to use a relay. A relay is a Deep Security Agent where you have enabled the relay feature. Relays update your agents more quickly, reduce manager load, and save internet connection or WAN bandwidth. For information on how to set up relays, see Distribute security and software updates with relays.

How do agents validate the content of updates provided by the manager?

All security content has integrity validation performed on it using methods that include digital signatures and checksums as well as other non-disclosed methods.
