Security

In this section:

1. Access Control Lists
   Layer 3 (IPv4 and IPv6) access control lists (ACLs) permit or deny packets according to rules included in the ACLs. When a packet is received or sent, the device compares its header fields against the rules in applied ACLs. This comparison is done sequentially, in the order the rules are entered or on the sequence numbers you specify. Based on the comparison, the device either forwards or drops the packet. Only a minimal number of ACL configurations are supported in the web interface.
2. AAA Servers
   Authentication, authorization, and accounting (AAA) is a set of services to regulate access to system resources, enforce privilege policies, and assess usage. These processes ensure effective network management and security. The AAA server is a network server that is used for access control which handles user requests for access to computer resources and provides AAA services: authentication, authorization, and accounting.
