Configuring Access Rules

Access rules provide you with the ability to control user access. Rules set from the Policies > Rules > Access Rules page are checked against the user group memberships returned from a SSO LDAP query, and are applied automatically. Access rules are network management tools that allow you to define inbound and outbound access policy, configure user authentication, and enable remote management of the Security Appliance. The Rules > Access Rules page provides a sortable access rule management interface.

More specific policy rules should be given higher priority than general policy rules. The general specificity hierarchy is source, destination, service. User identification elements, for example, user name and corresponding group permissions, are not included in defining the specificity of a policy rule.

By default, the firewall’s stateful packet inspection allows all communication from the LAN to the Internet, and blocks all traffic to the LAN from the Internet.

Additional network access rules can be defined to extend or override the default access rules. For example, access rules can be created that block certain types of traffic such as IRC from the LAN to the WAN, or allow certain types of traffic, such as Lotus Notes database synchronization, from specific hosts on the Internet to specific hosts on the LAN, or restrict use of certain protocols such as Telnet to authorized users on the LAN.

The ability to define network access rules is a powerful tool. Using custom access rules can disable firewall protection or block all access to the Internet. Use caution when creating or deleting network access rules.
