Q: What does the signature library of a security product mean? Why should it be upgraded?
A: The signature library is a database file that stores a certain category of signature information. By utilizing the signature information stored in the signature library , a firewall can effectively identify various features of the traffic passing through it.
As an important component of the firewall security protection system, the signature library usually needs to be combined with the business characteristics related to security detection and defense (such as application identification, intrusion prevention, anti-virus, etc.) in order to enhance the firewall device's security detection capability. Due to the constant emergence of new application/protocol types and attack methods in the network, the signature library in the firewall device needs to be updated to the latest version in a timely manner to improve threat detection capability and efficiency.
Network administrators can update the latest released feature library to the firewall device through various methods. H3C support upgade signature library online or local upgrade by using packeage downloaded from H3C Official website.
Note: The signature library upgrade function for each business requires the installation of a license to be used. After the license expires, each business can continue to work with the existing signature library in the device, but cannot upgrade the signature library .
