Product Description

This section provides an overview of the Catalyst 9200/9200L Series Switches Target of Evaluation (TOE).  The TOE is comprised of both software and hardware. The hardware is comprised of the hardware models as described in Section 1.5 of the Security Target.  The software is comprised of the Universal Cisco Internet Operating System (IOS) XE software image Release IOS-XE 16.12. 

The 9200/9200L Series Switches that comprises the TOE has common hardware characteristics. These characteristics affect only non-TSF relevant functions of the switches (such as throughput and amount of storage) and therefore support security equivalency of the switches in terms of hardware.

The Catalyst 9200/9200L Series Switches primary features include the following:

  • Central processor that supports all system operations;
  • Dynamic memory, used by the central processor for all system operation;
  • CPU complex with 8-GB memory, and 16 GB of flash and external USB 3.0 SSD pluggable storage slot (delivering 120GB of storage with an option SSD drive);  
  • Non-volatile read-only memory (ROM) is used to store the bootstrap program and power-on diagnostic programs and
  • Non-volatile random-access memory (NVRAM) is used to store switch configuration parameters that are used to initialize the system at start-up.
  • Physical network interfaces (minimally two) (e.g. RJ45 serial and standard 10/100/1000 Ethernet ports).  Some models have a fixed number and/or type of interfaces; some models have slots that accept additional network interfaces;
  • Dedicated management port on the switch, RJ-45 console port and a USB mini-Type B console connection and
  • Resiliency with Field-Replaceable Units (FRU) and redundant power supply, fans, and modular uplinks.

Cisco IOS-XE is a Cisco-developed highly configurable proprietary operating system that provides for efficient and effective routing and switching.  Although IOS-XE performs many networking functions, this TOE only addresses the functions that provide for the security of the TOE itself.

Environmental Strengths

The TOE is comprised of several security features. Each of the security features identified above consists of several security functionalities, as identified below.

·        Security Audit

·        Cryptographic Support

·        Identification and Authentication

·        Security Management

·        Protection of the TSF

·        TOE Access

·        Trusted Path/Channels

 

Security Audit

The Cisco Catalyst 9200/9200L Series Switches provides extensive auditing capabilities. The TOE generates a comprehensive set of audit logs that identify specific TOE operations. For each event, the TOE records the date and time of each event, the type of event, the subject identity, and the outcome of the event.

Auditable events include:

·        failure on invoking cryptographic functionality such as establishment, termination and failure of cryptographic session establishments and connections;

·        creation and update of Secure Association Key

·        modifications to the group of users that are part of the Authorized Administrator roles;

·        all use of the user identification mechanism;

·        any use of the authentication mechanism;

·        Administrator lockout due to excessive authentication failures;

·        any change in the configuration of the TOE;

·        changes to time;

·        initiation of TOE update;

·        indication of completion of TSF self-test;

·        maximum sessions being exceeded;

·        termination of a remote session;

·        attempts to unlock a termination session and 

·        initiation and termination of a trusted channel

The TOE is configured to transmit its audit messages to an external syslog server. Communication with the syslog server is protected using IPsec and the TOE can determine when communication with the syslog server fails.  If that should occur, the TOE can be configured to block new permit actions. 

The audit logs can be viewed on the TOE using the appropriate IOS-XE commands.  The records include the date/time the event occurred, the event/type of event, the user associated with the event, and additional information of the event and its success and/or failure.  The TOE does not have an interface to modify audit records, though there is an interface available for the Authorized Administrator to clear audit data stored locally on the TOE.

Cryptographic Support

The TOE provides cryptography in support of other TOE security functionality.  All the algorithms claimed have CAVP certificates (Operation Environment – (9200 (ARM A53), 9200L (ARM A53) processors).

The TOE leverages the IOS Common Cryptographic Module (IC2M) Rel5 as identified in the table below.  The IOS software calls the IOS Common Cryptographic Module (IC2M) Rel5 (Firmware Version: Rel 5) that has been validated for conformance to the requirements of FIPS 140-2 Level 1.

In addition, the TOE supports MACsec using proprietary Unified Access Data Plane (UADP) ASIC.  The MACsec Controller (MSC) is embedded within the ASICs that are utilized within Cisco hardware platforms.

The TOE provides cryptography in support of VPN connections that includes 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. 

The TOE authenticates and encrypts packets between itself and a MACsec peer.  The MACsec Key Agreement (MKA) Protocol provides the required session keys and manages the required encryption keys to protect data exchanged by the peers.

The cryptographic services provided by the TOE are described in Table 2 below.

Identification and authentication

The TOE performs two types of authentication: device-level authentication of the remote device (TOE 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.  

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 as well as mandatory password complexity rules.  The TOE provides administrator authentication against a local user database.  Password-based authentication can be performed on the local serial console or SSHv2 interfaces.  The SSHv2 interface also supports authentication using SSH keys.  The TOE 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 connection to the remote authentication server is secured using IPsec.

The TOE also provides an automatic lockout when a user attempts to authenticate and enters invalid information.  When the threshold for a defined number of failed authentication attempts has exceeded the configured allowable attempts, the user is locked out until an Authorized Administrator can reenable the user account. 

The TOE uses X.509v3 certificates as defined by RFC 5280 to support authentication for IPsec connections.

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 serial console connection.  The TOE provides the ability to securely manage:

·        Administration of the TOE locally and remotely;

·        Configuration of warning and consent access banners;

·        Configuration of session inactivity thresholds;

·        Updates of the TOE software;

·        Configuration of authentication failures;

·        Configuration of the audit functions of the TOE;

·        Configuration of the TOE provided services;

·        Configuration of the cryptographic functionality of the TOE;

·        Generate, install and manage PSK;

·        Manage the Key Server, CAK and MKA participants and

·        Configure lockout time interval for excessive authentication failures

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.  The privileged administrator is the Authorized Administrator of the TOE who has the ability to enable, disable, determine and modify the behavior of all of the security functions of the TOE as described in this document.

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

The TOE is also able to detect replay of information received via secure channels (MACsec).  The detection is applied to network packets that terminate at the TOE, such as trusted communications between the TOE and an IT entity (e.g., MACsec peer).  If replay is detected, the packets are discarded.

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.  The TOE provides the Authorized Administrators the capability to update the TOE’s clock manually to maintain a reliable timestamp. 

Finally, the TOE performs testing to verify correct operation of the TOE itself and that of the cryptographic module.

TOE Access

The 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.

Trusted path/Channels

The TOE allows trusted path to be established to itself from remote administrators over SSHv2 and initiates outbound IPsec trusted channels to transmit audit messages to remote syslog servers.  In addition, IPsec is used as a trusted channel between the TOE and the remote authentication servers, as well as to protect the communications with the CA server. 

The TOE also supports MACsec secured trusted channels between itself and MACsec peers.
