Security State | |
Security |
Security refers to the Network Address Translation (NAT) features. By default, security is enabled. |
Firewall | Enabled: Firewall
feature is activated. All IP traffic on existing security interfaces that
are NOT featured in a Firewall policy is blocked. Disabled: Firewall feature is not activated. |
Intrusion Detection | To enable/disable the
detection of any illegitimate users. Enabled: Your network is able to detect intrusion. Disabled: Your network is not able to detect any intrusion. |
Security Level | |
Security level | Applicable only when Firewall
feature is enabled. Once you have selected a security level, all IP
traffic except the default policies specified will be blocked by
the Firewall. none - blocks all IP traffic for every security interface. High - Your system uses the high firewall security level, providing a high level of firewall security between interfaces. Medium - Your system uses the medium firewall security level, providing a medium level of firewall security between interfaces. Low - Your system uses the low firewall security level, providing a low level of firewall security between interfaces. |
Security Interfaces | |
Name | A name that identifies an existing security interface. |
Type | external: An interface that
connects to the external network. internal: An interface that connects to the internal network. |
NAT | Network Address Translation. Is enabled by default. |
Policies, Triggers and Intrusion Detection | |
Firewall Policy Configuration | Allows you to create a policy between two interface types. (A policy is the collective term for the rules that apply to incoming and outgoing traffic between two interface types). |
Firewall Trigger Configuration | Allows you to add trigger to the Firewall feature. A trigger allows an application to open a secondary port in order to transport packets. The trigger opens a secondary port dynamically, and allows you to specify the length of time that it can remain inactive before it is closed. |
Configure Intrusion Detection | To enable/disable the detection of any illegitimate users. |
Security Interfaces have been defined by default. You may delete the existing interfaces before adding a new one.
