4 Security Objectives

This section identifies the security objectives for the TOE and its supporting environment. The security objectives identify the responsibilities of the TOE and its environment in meeting the security needs.

4.1 Security Objectives for the TOE

The specific security objectives are as follows:

O.I&A	The TOE must be able to identify and authenticate users prior to allowing access to TOE
	functions and data.
O.AUDIT	The TOE must record audit records for data accesses and use of the System functions.
O.SELFPROTECT	The TOE must protect itself from unauthorized modifications and access to its functions
	and data.
O.FUNCTIONS	The TOE must provide functionality that enables only authorized users to establish VPN
	sessions with the TOE using the IPSec protocol.
O.ADMIN	The TOE must provide facilities to enable an authorized administrator to effectively
	manage the TOE and its security function, and must ensure that only authorized
	administrators are able to access such functionality.
O.TEST	The TOE must provide functionality that enables testing of its correct functioning and
	integrity.
O.REPLAY	The TOE must provide functionality that enables detection of replay attack and take
	appropriate action if an attack is detected.
O.CONFIDENT	The TOE must use the IPSec tunneling protocol to ensure confidentiality of data
	transmitted between the Nortel VPN Client and the Nortel VPN Router, and/or between
	two Nortel VPN Routers.
O.INTEGRITY	The TOE must use the IPSec tunneling protocol to ensure integrity of data transmitted
	between the Nortel VPN Client and the Nortel VPN Router, and/or between two Nortel
	VPN Routers.
O.FILTER	The TOE must filter all incoming and outgoing packets that pass through it, and accept or
	reject packets based on their attributes.
