The TOE is Cisco Integrated Service Routers Generation 2 (ISR G2). The Cisco ISR G2 is a router platform that provides connectivity and security services onto a single, secure device. These routers offer broadband speeds and simplified management to small businesses, and enterprise small branch, and teleworkers. The Cisco ISR G2 provides single-device security and routing solutions for protecting the network.
","evaluation_configuration":"","security_evaluation_summary":"The evaluation was carried out in accordance with the Common Criteria Evaluation and Validation Scheme (CCEVS) process and scheme. The criteria against which the Cisco ISR G2 routers were judged are described in the Common Criteria for Information Technology Security Evaluation, Version 3.1 rev 4. The evaluation methodology used by the evaluation team to conduct the evaluation is the Common Methodology for Information Technology Security Evaluation, Version 3.1 rev 4. Leidos Inc. (formerly Science Applications International Corporation (SAIC)) determined that the TOE satisfies the requirements specified in Protection Profile for Network Devices, Version 1.1, 8 June 2012 with Network Device Protection Profile (NDPP) Extended Package VPN Gateway, Version 1.1, 12 April 2013. The product, when configured as identified in the Cisco ISR G2 Common Criteria Operational User Guidance ad Preparative Procedures document, satisfies all of the security functional requirements stated in the Cisco Integrated Services Router (ISR G2) Security Target (Version 1.0). The project underwent CCEVS Validator review. The evaluation was completed in March 2014. Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report prepared by CCEVS.
","environmental_strengths":"Security Audit
\r\nThe Cisco ISR G2 routers provide extensive auditing capabilities. The TOE can audit events related to cryptographic functionality, information flow control enforcement, identification and authentication, and administrative actions. The Cisco ISR G2 routers generate an audit record for each auditable event. The administrator configures auditable events, performs back-up operations and manages audit data storage. The TOE provides the audit trail protection by providing remote backup to a syslog server over an encrypted channel.
\r\nCryptographic Support
\r\nThe TOE provides cryptography in support of other Cisco ISR G2 security functionality. The cryptographic algorithms implemented in support of this functionality have been NIST-validated and the relevant Cryptographic Algorithm Validation Program (CAVP) certificate numbers are listed in Table 7 of the ST. The TOE provides cryptography in support of VPN connections and remote administrative management via SSHv2. The TOE can act as a certification authority, signing and issuing certificates to the TOE and other devices. The TOE can also use X.509v3 certificates for securing IPsec, SSH, and TLS sessions.
\r\nUser Data Protection
\r\nThe TOE ensures that packets transmitted from the TOE do not contain residual information from previous packets. Packets that are not the required length use zeroes for padding so that residual data from previous traffic is never transmitted from the TOE.
\r\nIdentification and Authentication
\r\nThe TOE performs two types of authentication: device-level authentication of the remote device (VPN peers) and user authentication for the authorized administrator of the TOE. Device-level authentication allows the TOE to establish a secure channel with a trusted peer. The secure channel is established only after each device authenticates the other. Device-level authentication is performed via IKE/IPsec mutual authentication. The IKE phase authentication for the IPsec communication channel between the TOE and authentication server and between the TOE and syslog server is considered part of the Identification and Authentication security functionality of the TOE.
\r\nThe TOE provides authentication services for administrative users wishing to connect to the TOEs secure CLI administrator interface. The TOE requires authorized administrators to authenticate prior to being granted access to any of the management functionality. The TOE can be configured to require a minimum password length of 15 characters as well as mandatory password complexity rules as defined in the claimed PPs. The TOE provides administrator authentication against a local user database. Password-based authentication can be performed on the serial console or SSH interfaces. The SSHv2 interface also supports authentication using SSH keys. The TOE optionally supports use of a RADIUS or TACACS+ AAA server (part of the IT Environment) to facilitate authentication (including remote authentication, or password-based authentication) of administrative users attempting to connect to the TOE’s CLI.
\r\nThe TOE provides an automatic lockout when a user attempts to authenticate and enters invalid information. After a defined number of authentication attempts fail exceeding the configured allowable attempts, the user is locked out until an authorized administrator can enable the user account.
\r\nThe TOE uses X.509v3 certificates as defined by RFC 5280 to support authentication for IPsec, TLS, and SSH connections.
\r\nSecurity Management
\r\nThe TOE provides secure administrative services for management of general TOE configuration and the security functionality provided by the TOE. All TOE administration occurs through a either a secure SSHv2 session, or via a local console connection. The TOE provides the ability to securely manage all TOE administrative users; all identification and authentication; all audit functionality of the TOE; all TOE cryptographic functionality; the timestamps maintained by the TOE; and TOE configuration file storage and retrieval. Administrators can create configurable login banners to be displayed at time of login, and can also define an inactivity timeout for each admin interface to terminate sessions after a set period of inactivity.
\r\nPacket Filtering
\r\nThe TOE provides packet filtering and secure IPsec tunneling. The tunnels can be established between two trusted VPN peers as well as between remote VPN clients and the TOE. More accurately, these tunnels are sets of security associations (SAs). The SAs define the protocols and algorithms to be applied to sensitive packets and specify the keying material to be used. SAs are unidirectional and are established per the ESP security protocol. An authorized administrator can define the traffic that needs to be protected via IPsec by configuring access lists (permit, deny, log) and applying these access lists to interfaces using crypto map sets.
\r\nProtection of the TSF
\r\nThe TOE protects against interference and tampering by untrusted subjects by implementing identification, authentication, and access controls to limit configuration to authorized administrators.
\r\nThe TOE internally maintains the date and time. This date and time is used as the timestamp that is applied to audit records generated by the TOE. Administrators can update the TOE’s clock manually, or can configure the TOE to use NTP to synchronize the TOE’s clock with an external time source. Finally, the TOE performs testing to verify correct operation of the router itself and that of the cryptographic module.
\r\nThe TOE can terminate inactive sessions after an authorized administrator configurable time-period. Once a session has been terminated, the TOE requires the user to re-authenticate to establish a new session. The TOE can also display an authorized administrator specified banner on the CLI management interface prior to allowing any administrative access to the TOE.
\r\nResource Utilization
\r\nThe TOE provides the capability of controlling and managing resources so that a denial of service will not occur. The resource allocations are configured to limit the number of concurrent administrator sessions.
\r\nTOE Access
\r\nThe TOE can terminate inactive sessions after an authorized administrator configurable time- period. Once a session has been terminated, the TOE requires the user to re-authenticate to establish a new session.
\r\nThe TOE also provides the administrator with the ability to display a notification of use banner on the CLI management interface prior to allowing any administrative access to the TOE.
\r\nTrusted Path/Channels
\r\nThe TOE establishes a trusted path between the appliance and the CLI, syslog server, NTP server and if configured, an external authentication server using IPsec.
