required to use
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.
The TOE is required to use the specified tunneling protocol to better protect the confidentiality of the data transmitted between its different parts. The RSA suite of algorithms and the Diffie- Hellman algorithm used by the TOE for cryptographic operations must be implemented according to RFC 3447 for RSA and RFC 2631 for
All the operations between the different parts of the TOE must be scrutinized by the TOE against the VPN information flow control SFP and the Firewall information flow control SFP using specific security attributes. During this task, the TOE is required to make use of its Firewall, NAT, and IPSec tunneling protocol implementations [FDP_IFC.2(a), FDP_IFF.1(a), FDP_UCT.1, and FDP_UIT.1].
O.FUNCTIONS The TOE must provide functionality that enables only authorized user to establish VPN sessions with the TOE using IPSec protocol.
| Using the Access Control SFP, the TSF is required to provide the ability to restrict managing the |
| behavior, and modifying the security attributes of functions of the TOE to authorized users of the |
| TOE [FMT_MOF.1(a,b)]. The TOE is required to only accept secure values for security attributes |
| [FMT_MSA.2]. The TOE SFPs are required to provide restrictive default values and to |
| alternatively provide authorized users the ability to override default values for security attributes |
| that are used to enforce the SFP [FMT_MSA.3(a,b,c)]. |
| The TSF is required to perform security management functions such as create |
| roles to user |
| administrative and user roles that exist for the TOE [FMT_SMR.1]. |
| The TSF is required to provide a logically distinct and protected communication path for secure |
| VPN communication with remote users [FTP_TRP.1]. |
O.ADMIN | The TOE will provide facilities to enable an authorized administrator to effectively manage |
| the TOE and its security function, and will ensure that only authorized administrators are |
| able to access such functionality. |
| The TSF is required to provide the ability to restrict managing the behavior, and modifying the |
| security attributes of functions of the TOE to authorized users of the TOE [FMT_MOF.1(a,b)]. |
| The TSF is required to enforce the Access Control SFP to restrict the ability to modify the security |
| attributes to authorized administrators [FMT_MSA.1(a,b,c,d,e)]. |
| The TOE is required to only accept secure values for security attributes [FMT_MSA.2]. The TOE |
| SFPs are required to provide restrictive default values and to alternatively provide authorized users |
| the ability to override default values for security attributes that are used to enforce the SFP |
| [FMT_MSA.3(a,b,c)]. |
