Restrictions and Precautions

Restrictions and Precautions

This section describes the restrictions and precautions for you to know when configuring update center.

  • The delivered device has the IPS signature database, antivirus signature database, application identification signature database used by the AP, and application identification signature database used by the Central AP of the default version but no malicious domain name signature database.

  • If the Central AP can directly access the update server, the Central AP uses HTTP to send update requests and uses FTP to download signature databases. Therefore, you need to configure security policies that permit HTTP and FTP traffic as well as user-defined service traffic in the connection to FTP data channels, with the protocol being TCP and destination port ranging from 10001 to 15000. HTTP and FTP are insecure. Therefore, you need to strictly limit the matching conditions of security policies.

  • If no schedule time is specified, the Central AP updates the signature database daily at any point during the time range 22:00 to 07:59 by default. You set the time for scheduled update based on your network conditions, but ensure that the update does not take up the network resources of normal services.

  • If you need to perform the update immediately, take the network conditions into consideration and ensure that the update does not take up the network resources of normal services. After the scheduled update is enabled, if the network rate is too low and impacts the services and performance of Central AP, you can abort the update.
