Solutions built on this platform are load balancers. They are full proxies that give visibility into, and the power to control—inspect and encrypt or decrypt—all the traffic that passes through your network. Underlying all BIG-IP hardware and software is F5’s proprietary operating system, TMOS, which provides unified intelligence, flexibility, and programmability. With its application control plane architecture, TMOS gives you control over the acceleration, security, and availability services your applications require. TMOS establishes a virtual, unified pool of highly scalable, resilient, and reusable services that can dynamically adapt to the changing conditions in data centers and virtual and cloud infrastructures. The module has been tested on the following multichip standalone devices with the firmware version 14.1.0.3 EHF.

In the operation mode the module supports two modes of operation: • in "FIPS mode" (the FIPS Approved mode of operation) only approved or allowed security functions with sufficient security strength can be used. • in "non-FIPS mode" (the non-Approved mode of operation) only non-approved security functions can be used. The module enters operational mode after power-up tests succeed. Once the module is operational, the mode of operation is implicitly assumed depending on the security function invoked and the security strength of the cryptographic keys. Critical Security Parameters (CSPs) used or stored in FIPS mode are not used in non-FIPS mode, and vice versa. In the FIPS Approved Mode, the cryptographic module will provide the following CAVP certified cryptographic algorithms. Here the Control, or Management, plane refers to the connection from an administrator to the BIG-IP for system management. The Data Plane refers to the traffic passed between external entities and internal servers F5® Device Cryptographic Module FIPS 140-2 Non-Proprietary Security Policy © 2022 F5.

The FIPS140-2 role of User is mapped to multiple BIG-IP roles which are responsible for different components of the system (e.g. auditing, certificate management, user management, etc.). The user can access the module through Web Interface described below. • Crypto Officer (CO) role: Crypto officer is represented by the administrator of the BIG-IP. This entity performs module installation and initialization. This role has full access to the system and has the ability to create, delete, and manage other user roles on the system. The module supports concurrent operators belonging to different roles: one CO and one User role, which creates two different authenticated sessions, achieving the separation between the concurrent operators. • One interface can be used to access the module: Web Interface: The Web interface consists of HTTPS over TLS interface which provides a graphical interface for system management tools. The web interface can be accessed from a TLS-enabled web browser. • Note: The module does not maintain authenticated sessions upon power cycling. Power-cycling the system requires the authentication credentials to be re-entered. Authentication data is protected against unauthorized disclosure, modification and substitution by the Operating System. Additionally, when entering authentication data through the Web interface, any character entered will be obfuscated (i.e. replace the character entered with a dot on the entry box). FIPS 140-2 Role BIG-IP Role Purpose of Role Crypto Officer Administrator Main administrator of the of the BIG-IP system. This role has complete access to all objects on the system. Entities with this role cannot have other roles on the system. User Auditor Entity who can view all configuration data on the system, including logs and archives. Certificate Manager Entity who manages digital certificates and keys. Firewall Manager Grants a user permission to manage all firewall rules and supporting objects. Notably, the Firewall Manager role has no permission to create, update, or delete non-network firewall configurations, including Application Security or Protocol Security policies. iRule Manager Grants a user permission to create, modify, view, and delete iRules. Users with this role cannot affect the way that an iRule is deployed. F5® Device Cryptographic Module FIPS 140-2 Non-Proprietary Security Policy © 2022 F5. Inc. / atsec information security. This document can be reproduced and distributed only whole and intact, including this copyright notice. 19 of 44 FIPS 140-2 Role BIG-IP Role Purpose of Role Operator Grants a user permission to enable or disable nodes and pool members. When granted terminal access. Resource Manager Grants a user access to all objects on the system except BIG-IP user accounts. With respect to user accounts, a user with this role can view a list of all user accounts on the system but cannot view or change user account properties except for their own user account. Users with this role cannot have other user roles on the system. User Manager Entity who manages BIG-IP crypto officer accounts.

Character classes are defined as: digits (0-9), ASCII lowercase letters (a-z), ASCII uppercase letters (A-Z) Assuming a worst-case scenario where the password contains four digits, one ASCII lowercase letter and one ASCII uppercase letter. The probability to guess every character successfully is (1/10) ^4 * (1/26)^1 * (1/26)^1 = 1/6,760,000 which is much smaller than 1/1,000,000. The maximum number of login attempts is limited to 6 after which the account is locked. This means that at worst case an attacker has the probability of guessing the password in one minute as 6/6,760,000 which is less than the requirement of 1/100,000.

Table 11 lists the services and the corresponding CSPs used in each service. Table 10 provides a list of services for the management of the module where, CSPs involved in User Management Services include user password. Name Generation Storage Zeroization DRBG entropy input string Obtained from NDRNG. RAM Zeroized by device reboot DRBG V and Key values Derived from entropy string as defined by [SP800-90A] RAM TLS RSA private key Generated using FIPS 186-4 Key generation method and the random value used in the key generation is generated using SP800-90A DRBG. Disk Zeroized when key file is deleted or by secure erase option at boot. TLS RSA public key TLS ECDSA private key TLS ECDSA public key TLS Pre-Master Secret and Master Secret Established during the TLS handshake RAM Zeroized by closing TLS session or by or rebooting the device. Derived TLS session key (AES, HMAC) Derived from the master secret via SP800-135 TLS KDF User Password Entered by the user Disk Zeroized by secure erase option at boot or overwritten when password is changed Table 15 – Life cycle of CSPs The following sections describe how CSPs, in particular cryptographic keys, are managed during its life cycle. 6.1 Key Generation For generation of RSA and ECDSA keys, the module implements asymmetric key generation services compliant with [FIPS186-4] and using DRBG compliant with [SP800- 90A]. A seed (i.e. the random value) used in asymmetric key generation is obtained from [SP800-90A] DRBG. The module does not implement symmetric key generation as an explicit service. The symmetric keys used by the module are derived from shared secret by applying SP 800- 135 as part of the TLS protocol (section 6.2 SP 800-133r2). In accordance with FIPS 140-2 IG D.12, the cryptographic module performs Cryptographic Key Generation (CKG) for the seed used in the generation of asymmetric keys as per SP800-133 (vendor affirmed). 6.2 Key Establishment The module provides RSA Key wrapping scheme which is used as part of TLS protocol with the key derivation implemented by SP 800-135 TLS KDF. The module also includes a F5® Device Cryptographic Module FIPS 140-2 Non-Proprietary Security Policy © 2022 F5. Inc. / atsec information security. This document can be reproduced and distributed only whole and intact, including this copyright notice. 33 of 44 SP 800-38F key wrapping in the context of TLS protocol where a key may be within a packet or message that is encrypted and authenticated using approved authenticated encryption mode i.e. AES GCM or a combination method which includes approved symmetric encryption algorithm i.e. AES together with approved authentication method i.e. HMAC-SHA. These schemes provide the following security strength in FIPS mode: • RSA key wrapping provides between 112 or 128-bits of encryption strength • SP 800-38F key wrapping using approved authenticated encryption mode i.e. AES GCM provides between 128 and 256 bits of encryption strength • SP 800-38F key wrapping using a combination of approved AES encryption and HMAC authentication method provides between 128 and 256 bits of encryption strength • SP 800-38F key wrapping using approved authenticated encryption mode i.e. AES GCM provides 128 or 256 bits of encryption strength • SP 800-38F key wrapping using a combination of approved AES encryption and HMAC authentication method provides 128 or 256 bits of encryption strength 6.3 Key Entry / Output The module does not support manual key entry or intermediate key generation key output. During the TLS handshake, the keys that are entered or output to the module over the network, includes RSA/ECDSA public keys and the TLS pre-master secret. encrypted with RSA key only when using the RSA key exchange with TLS. For TLS with RSA key exchange, when module acts as a TLS client, the TLS pre-master secret is generated using DRBG and is output from the module wrapped with server’s public RSA key. When module acts as a TLS server, the TLS pre-master secret encrypted with module's RSA key is input into the module. Once the TLS session is established, any key or data transfer performed thereafter is protected by AES encryption. 6.4 Key / CSP Storage As shown in the above table most of the keys are stored in the non-volatile memory in plaintext form and are destroyed when released by the appropriate zeroization calls or the system is rebooted. The keys stored in plaintext in non-volatile memory are static and will remain on the system across power cycle and are only accessible to the authenticated administrator. 6.5 Key / CSP Zeroization The zeroization methods listed in the above Table, overwrites the memory occupied by keys with “zeros”. Additionally, the user can enforce it by performing procedural zeroization. For keys present in volatile memory, calling reboot command will clear the RAM memory. For keys present in non-volatile memory, using secure erase option (can only be triggered by the administrator during reboot of the device) will perform single pass zero write erasing the disk contents.

This document can be reproduced and distributed only whole and intact, including this copyright notice. 34 of 44 6.6 Random Number Generation The module employs a Deterministic Random Bit Generator (DRBG) based on [SP800- 90A] for the generation of random value used in asymmetric keys, and for providing an RNG service to calling applications. The Approved DRBG provided by the module is the CTR_DRBG with AES-256. The DRBG is initialized during module initialization. The module performs the health tests for the SP800-90A DRBG as defined per section 11.3 of SP800- 90A. The module uses a Non-Deterministic Random Number Generator (NDRNG) to seed the DRBG. A Continuous Random Number Generation Test (CRNGT) is performed on the output of the NDRNG prior to seeding the DRBG and also on the DRBG output. The NDRNG provides at least 256- bits of entropy to the DRBG during initialization (seed) and reseeding (reseed). The NDRNG is within its physical boundary.

This document can be reproduced and distributed only whole and intact, including this copyright notice. 35 of 44 7 Self-Tests 7.1 Power-Up Tests The module performs power-up tests automatically during initialization when the device is booted without requiring any operator intervention; power-up tests ensure that the module’s firmware is not corrupted and that the cryptographic algorithms work as expected. During the execution of power-up tests, services are not available and input and output are inhibited. Upon successful completion of the power-up tests, the module is initialized and enters operational mode where it is accessible for use. If the module fails any of the power-up tests, it enters into the ‘Halt Error’ state and halts the system. In this state, the module will prohibit any data outputs and cryptographic operations and will not be available for use. The module will be marked unusable and the administrator will need to reinstall the module to continue. 7.1.1 Integrity Tests The integrity of the module is verified by comparing the MD5 checksum value of the installed binaries calculated at run time with the stored value computed at build time. If the values do not match the system enters halt error state and the device will not be accessible. In order to recover from this state, the module needs to be reinstalled. 7.1.2 Cryptographic algorithm tests The module performs self-tests on all FIPS-Approved cryptographic algorithms supported in the approved mode of operation and is done on the Data Plane as well as Control Plane side, using the Known Answer Test (KAT) and Pair-wise Consistency Test (PCT) as listed in the following table: Algorithm8 Test • Control Plane Self-tests CTR_DRBG KAT using AES 256-bit with and without derivation function AES KAT of AES encryption with GCM mode and 128-bit key KAT of AES encryption/decryption9 with ECB mode and 128-bit key RSA KAT of RSA PKCS#1 v1.5 signature generation with 2048 bit key and SHA-256 KAT of RSA PKCS#1 v1.5 signature verification with 2048 bit key and SHA-256 ECDSA PCT of ECDSA signature generation and verification with P-256 curve 8 The module also includes KATs for ECDH shared secret computation but it is a non-approved algorithm hence it is not listed in this table. 9 Encryption and Decryption known answer tests are performed separately F5® Device Cryptographic Module FIPS 140-2 Non-Proprietary Security Policy © 2022 F5.

On demand self-tests can be invoked by powering-off and powering-on the system in order to initiate the same cryptographic algorithm tests executed during power-up. During the execution of the on-demand self-tests, crypto services are not available and no data output or input is possible. 7.3 Conditional Tests The module performs conditional tests on the cryptographic algorithms shown in the following table. If the module fails any of these tests, the device reboots and enters into the Halt Error state prohibiting any data output or cryptographic operations and the module will be inoperable. The module must be re-installed in order to clear the error condition. F5® Device Cryptographic Module FIPS 140-2 Non-Proprietary Security Policy © 2022 F5. Inc. / atsec information security.

The hardware devices are shipped directly from the hardware manufacturer/authorized subcontractor via trusted carrier and tracked by that carrier. The hardware is shipped in a sealed box that includes a packing slip with a list of components inside, and with labels outside printed with the product nomenclature, sales order number, and product serial number. Upon receipt of the hardware, the customer is required to perform the following verifications: • Ensure that the shipping label exactly identifies the correct customer name and address as well as the hardware model. • Inspect the packaging for tampering or other issues. • Ensure that the external labels match the expected delivery and the shipped product. • Ensure that the components in the box match those on the documentation shipped with the product. • The hardware model can be verified by the model number given on the shipping label as well as on the hardware device itself. For FIPS compliance, the following steps defined in section 8.2 should be completed by the Crypto Officer prior to access to the device is allowed. 8.2 Crypto Officer Guidance 8.2.1 Installing Tamper Evident Labels Before the device is installed in the production environment, tamper-evident labels must be installed in the location identified for each module in section 4.1. The following steps should be taken when installing or replacing the tamper evident labels on the module. The instructions are also included in F5 Platforms: FIPS Kit Installation provided with each module. • Use the provided alcohol wipes to clean the chassis cover and components of dirt, grease, or oil before you apply the tamper evidence seals. • After applying the seal, run your finger over the seal multiple times using extra high pressure. • The seals completely cure within 24 hours. It is the responsibility of the Crypto Officer to inspect the tamper evident labels for damage or any missing labels as specified in Section 4. 8.2.2 Install Device • Follow the instructions in the "BIG-IP System: Initial Configuration" guide for the initial setup and configuration of the device. F5® Device Cryptographic Module FIPS 140-2 Non-Proprietary Security Policy © 2022 F5. Inc. / atsec information security. This document can be reproduced and distributed only whole and intact, including this copyright notice. 39 of 44 • Add the FIPS license when prompted during the GUI setup wizard. Guidance on Licensing the BIG-IP system can be found in https://support.f5.com/csp/article/K7752. 8.2.3 Password Strength Requirement The Crypto officer must modify the BIG-IP password policy to meet or exceed the requirements defined in Table 7 – Authentication of Roles. Instructions for this can be found in the “BIG-IP System: User Account Administration” guide. After assuming the role for the first time, the Crypto Officer shall replace the default password with one matching the password policy. 8.2.4 Additional Guidance The Crypto Officer should verify that the following specific configuration rules are followed in order to operate the module in the FIPS validated configuration: • All command shells other than tmsh are not allowed. For example, bash and other user-serviceable shells are excluded. Additionally note that the use of tmsh is considered non-approved because it makes used of SSH protocol that is marked as non-approved service in Table 12. Only access via GUI interface that makes use of TLS channel is considered approved. • Management of the module via the appliance's LCD display is not allowed. • Usage of f5-rest-node and iAppLX and provisioning of iRulesLX is not allowed. • Only the provisioning of AFM and LTM is included. • Remote access to the Lights Out / Always On Management capabilities of the system are not allowed. • Serial port console should be disabled after the initial power on and communications setup of the hardware. • On the i11800-DS device, the Cavium Nitrox-V must be disabled using lspci | grep -i encryption | awk ‘{print “device exclude “ $1;}’ > tmm_init.tcl command since full support is not available. 8.2.5 Version Configuration Once the device is installed, licensed and configured, the Crypto Officer should confirm that the system is installed and licensed correctly. 8.2.5.1 Version Confirmation The Crypto Officer should through the Big-IP Configuration Utility (Web interface) HTTPS access, navigate within the GUI to Main -> System -> Configuration -> Device -> General and verify the version shown with the approved version from Table 1 - Tested Modules. Any firmware loaded into the module other than version 14.1.0.3 EHF is out of the scope of this validation and will mean that the module is not operating as a FIPS validated module.

This document can be reproduced and distributed only whole and intact, including this copyright notice. 40 of 44 8.2.5.2 License Confirmation The FIPS validated module activation requires installation of the license referred as ‘FIPS license’. The Crypto Officer should through the Big-IP Configuration Utility (Web interface) HTTPS access, navigate within the GUI to Main -> System -> License and verify that the list of license flags includes the "FIPS 140-2 Compliant Mode”. 8.3 User Guidance The module supports two modes of operation. Table 11 – Crypto Services in FIPS mode of operation list the FIPS approved services and Table 12 – Services in non-FIPS mode of operation lists the non-FIPS approved services. Using the services in Table 5 – Non- Approved and Non-Compliant Cryptographic Algorithms/Modes means that the module operates in non-FIPS Approved mode for the particular session of a particular service, where the non-FIPS approved algorithm or mode was selected. AES-GCM IV is constructed in accordance with SP800-38D in compliance with IG A.5 scenario 1. The implementation of the nonce_explicit management logic inside the module ensures that when the IV exhausts the maximum number of possible values for a given session key, the module triggers a new handshake request to establish a new key. In case the module’s power is lost and then restored, the key used for the AES GCM encryption or decryption shall be re-distributed. The AES GCM IV generation is follows [RFC5288] and shall only be used for the TLS protocol version 1.2 to be compliant with [FIPS140-2_IG] IG A.5; thus, the module is compliant with [SP800-52].
