Physical Characteristics and Module Interfaces

Each PIX security appliance is a multi-chip standalone device. The cryptographic boundary is defined as encompassing the "top," "front," "left," "right," and "bottom" surfaces of the case and the "backplane" of the case which are not designed to accommodate a removable interface or service card, and inverse of the three-dimensional space within the case that would otherwise be occupied by an installed service card. The cryptographic boundary includes the connection apparatus between the service card and the motherboard/daughterboard that hosts the service card, but the boundary does not include the service card itself (except when a VAC+ is inserted into an available PIX Circuit Board Interface). In other words, the cryptographic boundary encompasses all hardware components within the case of the device except any installed modular service card (except when a VAC+ is inserted into an available PIX Circuit Board Interface).

Each PIX security appliance provides a number of physical and logical interfaces to the device, and the physical interfaces provided by the device are mapped to four FIPS 140-2 defined logical interfaces: data input, data output, control input, and status output.

The logical interfaces and their mapping are described in Table 2:

Roles and Services

The device can be accessed in one of the following ways:

Console Port

Telnet over IPSec

SSH

ASDM via HTTPS/TLS

As required by FIPS 140-2, there are two main roles in the PIX security appliance that operators may assume: a crypto officer role and a user role. The PIX security appliance supports role-based authentication, and the respective services for each role are described in the "Crypto Officer Services" section, and the "User Services" section.

Crypto Officer Services

The crypto officer role is responsible for the configuration and maintenance of the PIX security appliance and authenticates from the enable command (for local authentication) or the login command (for AAA authentication) from the user services. The crypto officer services consist of the following:

Configure the Device—Define network interfaces and settings; set the protocols the PIX security appliance will support; enable interfaces and network services; set system date and time; load authentication information; and configure authentication servers, filters and access lists for interfaces and users, and privileges.

Define Rules and Filters—Create packet filters that are applied to user data streams on each interface. Each filter consists of a set of rules, which define a set of packets to permit or deny based on characteristics such as protocol ID, addresses, ports, TCP connection establishment, or packet direction.

View Status—View the configuration, routing tables, active sessions, use gets to view SNMP MIB statistics, health, temperature, memory status, packet statistics, review accounting logs, and view physical interface status.

Manage the Device—Log off users, shut down or reload the PIX security appliance, view complete configurations, view full status, manage user rights, and restore configurations.

Set Encryption/Bypass—Set up the configuration tables for IP tunneling, set keys and algorithms to be used for each IP range or allow plaintext packets to be sent from specified IP address.

Install Service Card—Remove tamper-evident seals to install or replace service cards.

User Services

A user enters the system by accessing the console port with a terminal program or via IPSec protected Telnet or SSH session to a LAN port. The PIX security appliance will prompt the user for their password. If the password is correct, the user is allowed entry to the executive program. The services available to the user role consist of the following:

Status Functions—Image version currently running, installed hardware components, and version of hardware installed

Network Functions—Initiate diagnostic network services, such as ping

Directory Services—Display directory of files kept in Flash memory

Critical Security Parameters

The services accessing the Critical Security Parameters (CSPs), the type of access and which role accesses the CSPs are listed in the Table 3.

Table 3 Role and Service Access to Security Relevant Data Items

rwd: r = read, w = write, d = delete.

Authentication Mechanisms

The PIX security appliance supports either a password or digital certificates for authenticating IPSec users. To log on to the PIX security appliance for management purposes, an operator must connect to it through one of the management interfaces (Console Port, SSH, Telnet, or ASDM) and provide a password.

Table 4 describes the estimated strength of the authentication mechanism.

Table 4 Estimated Strength of Authentication Mechanism 

Authentication Type
Strength

Username Password mechanism

Passwords must be a minimum of 6 characters (see the "Secure Operation" section). The password can consist of alphanumeric values, a-zA-Z0-9, yielding 62 choices per character. The probability of a successful random attempt is 1/62^6, which is less than 1/1,000,000. This is also valid for RADIUS or TACACS+ shared secret keys.

Certificate based authentication

The PIX security appliance supports a public key based authentication with 1024 and 2048 (for RSA) bit keys.

A 1024-bit RSA key has at least 80-bits of equivalent strength. The probability of a successful random attempt is 1/2^80, which is less than 1/1,000,000.

A 2048-bit RSA key has at least 112-bits of equivalent strength. The probability of a successful random attempt is 1/2^112, which is less than 1/1,000,000.


Cryptographic Key Management

The PIX security appliances use a variety of critical security parameters during operation.

Self-Tests

The PIX security appliances include an array of self-tests that are run during startup and periodically during operations to prevent any secure data from being released and to ensure all components are functioning correctly.

The PIX security appliances perform all power-on self-tests automatically at boot-up when FIPS mode is enabled. All power-on self-tests must be passed before a user/crypto officer can perform services. The power-on self-tests are performed after the cryptographic systems are initialized but prior to the initialization of the LANs; this prevents the device from passing any data during a power-on self-test failure. In the unlikely event that a power-on self-test fails, an error message is displayed on the console followed by a system reboot.

Table 7 lists the conditional self-tests that the PIX security appliance performs.

Mitigation of Other Attacks

The PIX security appliances do not claim to mitigate any attacks in a FIPS-approved mode of operation above and beyond the protection inherently provided by the PIX security appliance.

Secure Operation

The Cisco PIX515/515E security appliances meet FIPS 140-2 Level 2 requirements.

This section describes how to place and keep the PIX security appliance in a FIPS-approved mode of operation. Operating the PIX security appliance without maintaining the settings described in the "Crypto Officer Guidance - System Initialization" section and "Crypto Officer Guidance - System Configuration" section will remove the PIX security appliance from the FIPS-approved mode of operation.

Crypto Officer Guidance - System Initialization

The PIX security appliance were validated with adaptive security appliance software version 7.0.4 (file name: pix704.bin). This is the only allowable image for FIPS-approved mode of operation.

To initialize the system, the crypto officer must perform the following steps:


Step 1 Ensure the security context mode is set to single mode by entering the following command:

(config)# mode single

Step 2 Ensure the firewall mode is set to routed mode by entering the following command:

(config)# no firewall transparent

Step 3 Disable the console output of system crash information by entering the following command:

(config)# crashinfo console disable

Step 4 Enable "FIPS Mode" to allow the device to internally enforce FIPS-compliant behavior, such as running power-on self tests and bypass test by entering the following command:

(config)# fips enable

Step 5 Install Triple DES/AES licenses to require the device to use Triple DES and AES (for data traffic and SSH).

Step 6 Disable password recovery by entering the following command:

(config)# no service password-recovery

Step 7 Set the configuration register to bypass ROMMON prompt at boot by entering the following command:

(config)# config-register 0x10011

Step 8 Define the failover key to ensure encryption of the link to redundant modules prior to enabling failover by entering the following command:

(config)# failover key hex <key>


Note Failover is not required for FIPS mode of operation. If failover is to be enabled, then the above configuration should be followed. Also, only LAN-based failover is allowed for FIPS mode of operation; serial link failover is not allowed in FIPS mode of operation. Failover should not be configured over the lowest-numbered interface (e.g., Ethernet 0); ports Ethernet 1 or above should be used. If the lowest-numbered interface is already implemented as the failover interface, the Crypto Officer should take the following action:
- Before upgrading to V7.0.4, copy the configuration to a location off the device
- Use a text editor to modify the interface configuration
- Change the failover cables to the specified failover interface
- Upgrade to V7.0.4 and reload the modified configuration


Step 9 Enable AAA authorization for the console by entering the following command:

(config-terminal)# aaa authentication serial console LOCAL
(config-terminal)# username <name> password <password>

Step 10 Enable AAA authorization for SSH and Telnet by entering the following command:

(config-terminal)# aaa authentication ssh console LOCAL
(config-terminal)# aaa authentication telnet console LOCAL

Step 11 Enable AAA authorization for Enable mode by entering the following command:

(config-terminal)# aaa authentication enable console LOCAL

Step 12 Specify Privilege Level 15 for crypto officer and Privilege Level 1 for user and set up username/password for each role by entering the following command:

(config-terminal)# username <name> password <password> privilege 15
(config-terminal)# username <name> password <password> privilege 1

Step 13 Ensure passwords are at least 6 characters long.

Step 14 All default passwords (e.g., enable, Telnet) should be replaced with new passwords.

Step 15 Apply tamper-evident labels as described in the "Applying Tamper-Evident Labels" section.


Note The Crypto Officer may install any Service Card modules that only provide a physical interface (e.g., PIX-1FE, PIX-1GE-66, PIX-4FE-66).The PIX modules are validated only with the VPN Acceleration Card PLUS (VAC+) for cryptographic acceleration; the legacy VAC is not supported in FIPS approved mode of operation.


Step 16 Reboot the PIX security appliance.


Crypto Officer Guidance - System Configuration

To configure the system, perform the following steps:


Step 1 Assign users a Privilege Level of 1.

Step 2 Define RADIUS and TACACS+ shared secret keys that are at least 6 characters long and secure all traffic between the PIX security appliance and the RADIUS/TACACS+ server via IPSec tunnel.


Note Use only if RADIUS/TACACS+ is configured.


Step 3 Configure the TLS protocol when using HTTPS to protect administrative functions. Due to known issues relating to the use of TLS with certain versions of the Java plugin, it is recommended that the customer upgrade to JRE 1.5.0_05 or later. The following configuration settings are known to work when launching ASDM in a TLS-only environment with JRE 1.5.0_05:

Configure the device to allow only TLSv1 packets.

(config)# ssl server-version tlsv1-only

Uncheck the SSL Version 2.0 check box in both the web browser and JRE security settings.

Check the TLS V1.0 check box in both the web browser and JRE security settings.

Step 4 Configure the PIX security appliance to use SSHv2 by entering the following command:

(config)# ssh version 2

Note All operators must still authenticate after remote access is granted.


Step 5 Configure the PIX security appliance to assure that any remote connections via Telnet are secured through IPSec.

Step 6 Configure the PIX security appliance to assure that only FIPS-approved algorithms are used for IPSec tunnels.

Step 7 Configure the PIX security appliance to assure that error messages can only be viewed by an authenticated crypto officer.

Step 8 SNMP packets must be sent over an IPSec tunnel for secure SNMP operations. PIX devices only support SNMP v1 and v2c, which use community strings for authentication and exchange data in clear-text.

Step 9 Disable the FTP, and TFTP servers as well as HTTP for performing system management.

Step 10 Ensure that installed digital certificates are signed using FIPS approved algorithms (SHA-1).

Step 11 Ensure that 512-bit and 768-bit RSA keys are not used.

Step 12 Ensure that the DSA algorithm uses at least a 512-bit modulus.


Approved Cryptographic Algorithms

The appliances support many different cryptographic algorithms; however, only FIPS approved algorithms may be used. The following cryptographic algorithms are to be used:

AES encryption/decryption

Triple DES encryption/decryption

SHA-1 hashing

SHA-1 HMAC for hashed message authentication

RSA signing and verifying

DSA signing and verifying

X9.31 for RNG

TLS for Layer 7 security


Note Pursuant to the DES Transition Plan and the approval of the Withdrawal of Federal Information Processing Standard (FIPS) 46-3, Data Encryption Standard (DES); FIPS 74, Guidelines for Implementing and Using the NBS Data Encryption Standard; and FIPS 81, DES Modes of Operation, the DES algorithm should not be used in FIPS approved mode of operation. The DES algorithm must not be used when the Triple DES/AES licenses are installed.


Each cryptographic implementation in the PIX security appliance software release with on-board acceleration has achieved the certifications listed in Table 8.

Applying Tamper-Evident Labels

All Critical Security Parameters (CSPs) are stored and protected within the PIX security appliance tamper-evident enclosure. The administrator is responsible for properly placing all tamper-evident labels. The security labels recommended for FIPS 140-2 compliance are provided in FIPS Kit. These security labels are very fragile and cannot be removed without clear signs of damage to the labels.

The crypto officer should inspect the tamper-evident labels periodically to verify they are intact and the serial numbers on the applied tamper-evident labels match the records in the security log.


Note The tamper-evident seals are produced from a special thin gauge vinyl with self-adhesive backing. Any attempt to open the PIX security appliance will damage the tamper-evident seals or the material of the PIX security appliance cover. Because the tamper-evident seals have non-repeated serial numbers, they may be inspected for damage and compared against the applied serial numbers to verify that the device has not been tampered with. Tamper-evident seals can also be inspected for signs of tampering, which include the following: curled corners, rips, and slices. The word Open may appear if the label was peeled back. Extra tamper-evident seals have been included in your FIPS kit to accommodate maintenance of your chassis.


To apply the serialized tamper-evident labels, perform the following steps:


Step 1 Turn off and unplug the system before cleaning the chassis and applying labels.

Step 2 Clean the chassis of any grease, dirt, or oil before applying the labels. Alcohol-based cleaning pads are recommended for this purpose.

Step 3 Apply a label on the front of the chassis so that the label covers the front plate and the top of the PIX515/515E chassis See Figure 1.

Step 4 Apply a label to cover the PIX515/515E side and bottom portions of the chassis. See Figure 1.

Figure 1 Cisco PIX 515/515E Front Tamper-Evident Label Placement

Step 5 On the back of the chassis, apply labels to cover the interface slots. SeeFigure 2.

Step 6 Apply a label to cover the PIX515/515E side and bottom portions of the case on the opposite side as in Step 3. SeeFigure 2.

Figure 2 Cisco PIX 515/515E Back Tamper-Evident Label Placement

Step 7 Record the serial numbers of the labels applied to the system in a security log.
