AES-GCM • The module’s AES-GCM implementation conforms to FIPS 140-3 IG C.H scenario #1 following RFC 5288 for TLS. The module is compatible with TLSv1.2 and provides support for the acceptable GCM cipher suites from SP800-52 Rev1, Section 3.3.1. The operations of one of the two parties involved in the TLS key establishment scheme were performed entirely within the cryptographic boundary of the module being validated. The counter portion of the IV is set by the module within its cryptographic boundary. When Page 16 of 42 ) This document can be reproduced and distributed only whole and intact, including this copyright notice. the IV exhausts the maximum number of possible values for a given session key, the first party, client or server, to encounter this condition will trigger a handshake to establish a new encryption key. The keys for the client and server negotiated in the TLSv1.2 handshake process (client_write_key and server_write_key) are compared and the module aborts the session if the key values are identical. In case the module’s power is lost and then restored, a new key for use with the AES GCM encryption/decryption shall be established. FIPS 186-4/186-5 • The module was algorithm tested based on the FIPS 186-4 standard for Digital Signatures prior to Feb 5, 2024.

The module implements two approved DRBGs based on SP800-90Arev1, including CTR_DRBG with Algo Cert. #A3566, and HMAC_DRBG with Algo Cert. #A3572. Those two DRBGs are used internally by the module (e.g. to generate symmetric keys, seeds for asymmetric key pairs, and random numbers for security functions). Each DRBG is seeded by the entropy source described in the table above. The module implements CTR_DRBG (AES-128/192/256) both with and without Derivation Function capability. Given that the module’s entropy source provides full entropy, CTR_DRBG without a Page 17 of 42 ) This document can be reproduced and distributed only whole and intact, including this copyright notice. derivation function is compliant with IG D.L. The module also implements HMAC_DRBG (SHA2- 512) with Prediction Resistance. Each DRBG is instantiated with a 384-bits long entropy input (corresponding to 384 bits of entropy) and provides at least 256 bits security strength for the cryptographic key generation while in the approved mode. Note: • ESV Cert. #E68 is for ION-1200, ION 1200-C-NA, ION 1200-C-ROW, ION 1200-C-5G- WW, ION 1200-S, ION 1200-S-C-NA, ION 1200-S-C-ROW, ION 1200-S-C-5G-WW and ION 3200 • ESV Cert. #E71 is for ION 5200 and ION 9200 2.9 Key Generation The module generates RSA, ECDSA, and ECDH asymmetric key pairs compliant with FIPS 186-4, using a NIST SP 800-90Ar1 CTR DRBG or HMAC DRBG for random number generation. In accordance with FIPS 140-3 IG D.H, the cryptographic module performs CKG for asymmetric keys as per section 5.1 of NIST SP 800-133rev2 (vendor affirmed) by obtaining a random bit string directly from an approved DRBG. The random bit string supports the required security strength requested by the calling application (without any V, as described in Additional Comments 2 of IG D.H.). 2.10 Key Establishment The module provides the following key/SSP establishment services in the approved mode of operation: • KAS-ECC Shared Secret Computation: o The module provides SP800-56Arev3 compliant key establishment according to FIPS 140-3 IG D.F scenario 2 path (2) with KAS-ECC shared secret computation. The shared secret computation provides between 128 and 256 bits of encryption strength. 2.11 Industry Protocols The module supports SSHv2, TLS v1.2, SNMPv3 and IPsec/IKEv2 industrial protocols. Please refer to the Security Function Implementations Table for more information. No parts of the SSH, TLS, SNMP and IPSec/IKE protocols, other than the KDFs, have been tested by the CAVP and CMVP. 3 Cryptographic Module Interfaces 3.1 Ports and Interfaces Physical Port Logical Interface(s) Data That Passes N/A Data Input API input parameters for data N/A Data Output API output parameters for data N/A Control Input API function calls Page 18 of 42 ) This document can be reproduced and distributed only whole and intact, including this copyright notice.

The Crypto Officer shall configure self-initiated cryptographic output capability. Prior to executing the self-initiated cryptographic output capability, the module conducts two independent internal actions to activate the capability to prevent the inadvertent output due to a single error. 4.7 Additional Information The module supports Unauthenticated service, where the unauthenticated users can run the self-test service by power-cycling the module. 5 Software/Firmware Security 5.1 Integrity Techniques The module performs the Software Integrity test by using HMAC-SHA2-256 (HMAC Cert. #A3566) during the Pre-Operational Self-Test. A Software Integrity Test Key (non-SSP) was preloaded to the module’s binary at the factory and used for software integrity test only at the pre-operational self-test. At Module’s initialization, the integrity of the runtime executable is verified using an HMAC-SHA2-256 digest which is compared to a value computed at build time. If at the load time the MAC does not match the stored, known MAC value, the module would enter an Error state with all crypto functionality inhibited. 5.2 Initiate on Demand Integrity test is performed as part of the Pre-Operational Self-Tests. It is automatically executed at power-on. The operator can power-cycle or reboot the module to initiate the software integrity test on-demand. This automatically performs the integrity test of all software components included within the boundary of the module. 6 Operational Environment 6.1 Operational Environment Type and Requirements Type of Operational Environment: Modifiable 7 Physical Security As the module is a software only module, the physical security requirements are not applicable. 8 Non-Invasive Security N/A for this module.

The full suite of self-tests is then executed. The same procedure may be employed by the operator to perform periodic self-tests. It is recommended that the Crypto Officer perform periodic testing of the module’s on-demand self-tests every 60 days to ensure all components are functioning correctly. 10.4 Error States Page 41 of 42 ) This document can be reproduced and distributed only whole and intact, including this copyright notice. Name Description Conditions Recovery Method Indicator Error State In the Error State, no cryptographic services are provided and the data output is prohibited Failed Pre-Operational Software Integrity Test Failed Conditional CAST Failed Conditional PCT Failed SP 800-90B Entropy Source Start-up/Continuous health tests Reboot the module System Halt Table 25: Error States If any of the above-mentioned self-tests fail, the module reports the cause of the error and enters an error state (there is only one error state). In the Error State, no cryptographic services are provided and data output is prohibited. The only method to recover from the error state is to reboot the module and perform the self-tests, including the pre-operational software integrity test and the conditional CASTs. The module will only enter into the operational state after successfully passing the pre-operational software integrity test and the conditional CASTs. 11 Life-Cycle Assurance 11.1 Installation, Initialization, and Startup Procedures The module is designed to handle the various stages of a module’s life-cycle. The sections below highlight the details for each stage. Secure Delivery Procedures The module is built into ION 6.1. There is no standalone delivery of the module as a software library. The vendor’s internal development process guarantees that the correct version of the module goes with the intended OS. Secure Operation The module meets all the Level 1 requirements for FIPS 140-3. Follow the secure operations provided below to place the module in the Approved mode. The software version is 1.0. The module is initiated into the Approved mode of operation via the following procedure. Note that a Palo Alto ION device running ION 6.1 is needed to access the APIs of the module. 1. Prepare the ION device for use and power-on 2. Using the Controller, navigate to the device that is to be initiated 3. Select “FIPS” a. Click “proceed” to begin initialization procedure 4. The module will begin initialization that includes the following: a. Zeroization of any sensitive information or data b. Power cycle of the device followed by running all self-tests 5. Once initialization is complete, the module provides the following status output: a. Device Mode: “fips” b. Self-tests: “Power-up self test successful” Page 42 of 42 ) This document can be reproduced and distributed only whole and intact, including this copyright notice. Once the module has completed initialization into the Approved mode of operation, any non- Approved configurations/algorithms are rejected automatically by the module and an error message is output. 11.2 Administrator Guidance Prisma SD-WAN Administrator's Guide from https://docs.paloaltonetworks.com/ 11.3 Non-Administrator Guidance Not Applicable. 11.4 End of Life End of life dates for the module are announced publicly via Palo Alto Networks’ services website. Crypto Officers should follow the procedure below for the secure destruction of their module: Note: This process will cause the module to no longer function after it has wiped all configurations and keys. 1) Access the module via SSH as Crypto Officer 2) Execute command: “disable system” a) Confirm command 3) Module will begin zeroization process and wipe all security parameters and configurations 12 Mitigation of Other Attacks This module is not designed to mitigate against any other attacks outside of the FIPS 140-3 scope.
