Security Security support on AT-iMG Models

iMG/RG Software Reference Manual (IPNetwork Functions)

4-58

• Intrusion Detection Settings (IDS) component; implements security measures to protect your network from

suspicious hosts

• Security component; manages the Security package, and enables security features such as management sta-

tions, triggers, security applications, session tracking and application services

4.2.2 Security support on AT-iMG Models

The Security module is the main module in the AT-iMG Models that acts as a server to the other two security

modules; Firewall and NAT, forming the Security System (see Figure 7).

This component allows you to:

• enable/disable all modules in the Security package (including the child modules; NAT and Firewal, that

cannot otherwise be configured)

• add IP interfaces to the Security package to create security interfaces that are used to configure the NAT

and Firewall child modules

• configure triggers to allow applications to open secondary port sessions

• configure IDSs (Intrusion Detection Settings)

• configure management stations to allow a specific host (or range of hosts) remote access to the device

without having to go through NAT and/or Firewall

• configure application services; to restrict access to a specific application service on a specific IP interface

once the interfaces have been defined as security interface

• configure logging: (On FIber D,E Modular and ADSL A,B,C models only) to track intrusion events, block-

ing-events and session-events.
