Product Description

The ASR1006 and ASR 1002X hardware models are included in the evaluation. The ASR1006 consists of a number of components including:

·         Chassis: The TOE chassis is a 6-RU form factor. The chassis is the component of the TOE in which all other TOE components are housed.

·         Embedded Services Processor (ESPr): The Cisco ASR1K Series ESPrs (ESP100) are responsible for the data-plane processing tasks, and all network traffic flows through them.

·         Route Processor (RP): The Cisco ASR1K Series RPs (RP1 and RP2) provide the advanced routing capabilities of the TOE. They also monitor and manage the other components in the Cisco ASR1K Series Aggregation Services.

·         Shared Port Adaptors (SPAs): Used for connecting to networks.  These SPAs interface with the TOE to provide the network interfaces that will be used to communicate on the network. 

The ASR 1002X is a 2-RU chassis that has integrated Route Processor and Embedded Services Processor. This chassis has 3 Shared Port Adaptor slots used for connecting to networks

The Cisco CSR 1000v Cloud Services Router provides a cloud-based virtual router deployed on a virtual machine (VM) instance on x86 server hardware. The Cisco CSR 1000v includes a virtual Route Processor and a virtual Forwarding Processor (FP) as part of its architecture. The Cisco CSR 1000v is deployed as a virtual machine on a hypervisor (VMWare ESXi 5.5) configured with no additional guest virtual machines.


Evaluated 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 TOE was evaluated 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.  The product, when delivered configured as identified in the Administrative Guidance Document (AGD), satisfies all of the security functional requirements stated in the Security Target. The project underwent CCEVS Validator review.  The evaluation was completed in January 2018.  Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report prepared by CCEVS.


Environmental Strengths

Security Audit

The TOE provides extensive auditing capabilities. The TOE can audit events related to cryptographic functionality, identification and authentication, and administrative actions. The TOE generates an audit record for each auditable event.  Each security relevant audit event has the date, timestamp, event description, and subject identity.  The administrator configures auditable events, performs back-up operations and manages audit data storage.  The TOE provides the administrator with a circular audit trail or a configurable audit trail threshold to track the storage capacity of the audit trail.  Audit logs are backed up over an encrypted channel to an external audit server.

Cryptographic Support

The TOE provides cryptography in support of other TOE security functionality.  All the algorithms claimed have CAVP certificates (Operational Environment – Intel Xeon processor).  The TOE leverages the IOS Common Criteria Module (IC2M) Rel5. The TOE provides cryptography in support of VPN connections and remote administrative management via SSHv2 and IPsec to secure the transmission of audit records to the remote syslog server. In addition, IPsec is used to secure the session between the TOE and the authentication servers.

Identification and Authentication

The 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 TOE supports use of IKEv1 (ISAKMP) and IKEv2 pre-shared keys for authentication of IPsec tunnels. 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.  

The TOE provides authentication services for administrative users to connect to the TOE’s 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. 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 AAA server (part of the IT Environment) for authentication of administrative users attempting to connect to the TOE’s CLI.

The 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.

Security Management

The TOE provides secure administrative services for management of general TOE configuration and the security functionality provided by the TOE.  All TOE administration occurs either through a secure SSHv2 session or via a local console connection.  The TOE provides the ability to securely manage:

·         Administration of the TOE locally and remotely;

·         All TOE administrative users;

·         All identification and authentication;

·         All audit functionality of the TOE;

·         All TOE cryptographic functionality;

·         The timestamps maintained by the TOE;

·         Update to the TOE and verification of the updates;

·         Configuration of IPsec functionality;

·         TOE configuration file storage and retrieval. 

The TOE supports two separate administrator roles: non-privileged administrator and privileged administrator.  Only the privileged administrator can perform the above security relevant management functions. Management of the TSF data is restricted to Security Administrators. The ability to enable, disable, determine and modify the behavior of all of the security functions of the TOE is restricted to authenticated administrators.

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. 

Packet Filtering

The 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.

Protection of the TSF

The TOE protects against interference and tampering by untrusted subjects by implementing identification, authentication, and access controls to limit configuration to Authorized Administrators.  The TOE prevents reading of cryptographic keys and passwords. 

Additionally, Cisco IOS-XE is not a general-purpose operating system and access to Cisco IOS-XE memory space is restricted to only Cisco IOS-XE functions.

The 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.

The TOE is able to verify any software updates prior to the software updates being installed on the TOE to avoid the installation of unauthorized software.

Whenever a failure occurs within the TOE that results in the TOE ceasing operation, the TOE securely disables its interfaces to prevent the unintentional flow of any information to or from the TOE and reloads.

TOE Access

The TOE can terminate or lock 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.  Sessions can also be terminated if an Authorized Administrator enters the “exit” command. 

The TOE can also display a Security Administrator specified banner on the CLI management interface prior to allowing any administrative access to the TOE.

Trusted Path/Channel

The TOE allows trusted paths to be established to itself from remote administrators over SSHv2, and initiates outbound IPsec tunnels to transmit audit messages to remote syslog servers.  In addition, IPsec is used to secure the session between the TOE and the authentication servers. The TOE can also establish trusted paths of peer-to-peer IPsec sessions.  The peer-to-peer IPsec sessions can be used for securing the communications between the TOE and authentication server/syslog server, as well as to protect communications with a CA or remote administrative console.
