FireEye HX Series: HX4402, HX4502, and HX4502D The FireEye HX Series: HX4402, HX4502, and HX4502D (the module) is a multi-chip standalone module validated at FIPS 140-2 Security Level 1. Specifically, the module meets the following security levels for individual sections in the FIPS 140-2 standard: Table 1 - Security Level for Each FIPS 140-2 Section # Section Title Security Level 1 Cryptographic Module Specification 1 2 Cryptographic Module Ports and Interfaces 1 3 Roles, Services, and Authentication 3 4 Finite State Model 1 5 Physical Security 1 6 Operational Environment N/A 7 Cryptographic Key Management 1 8 EMI/EMC 1 9 Self-Tests 1 10 Design Assurances 3 11 Mitigation Of Other Attacks N/A FIPS 140-2 Security Policy 6 2.1 Cryptographic Module Specification The FireEye HX series appliances enable security operations teams to correlate network and endpoint activity. Organizations can automatically investigate alerts generated by FireEye Threat Prevention Platforms, log management, and network security products, apply intelligence from FireEye to continuously validate Indicators of Compromises on the endpoints and identify if a compromise has occurred and assess the potential risk. Further, organizations can quickly triage the incident to understand the details and contain compromised endpoints with a single click and contain compromised devices within a single click workflow. 2.1.1 Cryptographic Boundary The cryptographic boundary for the module is defined as encompassing the "top," "front," "left," "right," and "bottom" surfaces of the case and all portions of the "backplane" of the case.

The logical interfaces and their mapping are described in the following table: Table 2 - Module Interface Mapping – HX4402/4502/4502D FIPS Interface Physical Interface Data Input (2x) 10/100/1000 BASE-T Management Port (1x) 100 BASE-T Management Port (IPMI) (2x) USB 2.0 Ports (2x) USB 3.0 Ports (HX4502, HX4502D) (1x) PS/2 Mouse Port (HX4402) (1x) PS/2 Keyboard Port (HX4402) (1x) Serial Port Data Output (2x) 10/100/1000 BASE-T Management Port (1x) 100 BASE-T Management Port (IPMI) (1x) Video Port (2x) USB 2.0 Ports (2x) USB 3.0 Ports (HX4502, HX4502D) (1x) Serial Port Control Input (2x) 10/100/1000 BASE-T Management Port (1x) 100 BASE-T Management Port (IPMI) (2x) USB 2.0 Ports (2x) USB 3.0 Ports (HX4502, HX4502D) (1x) PS/2 Mouse Port (HX4402) (1x) PS/2 Keyboard Port (HX4402) (1x) Serial Port (1x) Power Button (1x) Reset Button (HX4502, HX4502D) (4x) LCD Panel Buttons (HX4402) Status Output (2x) 10/100/1000 BASE-T Management Port (1x) 100 BASE-T Management Port (IPMI) (1x) Video Port (2x) USB 2.0 Ports (2x) USB 3.0 Ports (HX4502, HX4502D) (1x) Serial Port LEDs (HX4402 (4x), HX4502 (5x), HX4502D (5x)) Power Interface (2x) Power Ports FIPS 140-2 Security Policy 10 2.2 Roles, Services, and Authentication The following sections provide details about roles supported by the module, how these roles are authenticated and the services the roles are authorized to access. 2.2.1 Authorized Roles The module supports several different roles, including multiple Cryptographic Officer roles and a User role. The module does not support a maintenance role and/or bypass capability. Configuration of the module can occur over several interfaces and at different levels depending upon the role assigned to the user. There are multiple types of Cryptographic Officers that may configure the module, as follows: • Admin (CO role): The system administrator is a “super user” who has all capabilities. The primary function of this role is to configure the system. • Monitor (CO role): The system monitor has read-only access to some things the admin role can change or configure. • Operator (CO role): The system operator has a subset of the capabilities associated with the admin role. Its primary function is configuring and monitoring the system. • Analyst (CO role): The system analyst focuses on data plane analysis and possesses several capabilities, including setting up alerts and reports. • Auditor (CO role): The system auditor reviews audit logs and performs forensic analysis to trace how events occurred. • SNMP (CO role): The SNMP role provides system monitoring through SNMPv3. The Users of the module are the remote IT devices (user role) and remote management clients accessing the module via cryptographic protocols. These protocols include, SSH, TLS, and SNMPv3. Unauthenticated users are only able to access the module LEDs and power cycle the module. 2.2.2 Authentication Mechanisms The module supports identity-based authentication. Module operators must authenticate to the module before being allowed access to services, which require the assumption of an authorized role. The module employs the authentication methods described in the table below to authenticate Crypto-Officers and Users. Table 3 - Authentication Mechanism Details Role Type Of Authentication Authentication Strength Admin Password/Username All passwords must be between 8 and 32 characters. The passwords can consist of alphanumeric values, {a-z, A-Z, 0-9, and special characters}, the characters can thus be chosen from the 94 human readable ASCII characters on Monitor Operator FIPS 140-2 Security Policy 11 Role Type Of Authentication Authentication Strength Analyst an American QWERTY computer keyboard. Thus, the probability of a successful random attempt is 1/94^8 , which is less than 1 in 1,000,000. In the worst-case scenario, if (8) integers are used for an eight-digit password, the probability of randomly guessing the correct sequence is one (1) in 100,000,000 (this calculation is based on the assumption that the typical standard American QWERTY computer keyboard has 10 Integer digits. The calculation should be 10 ^ 8 = 100,000,000). Therefore, the associated probability of a successful random attempt is approximately 1 in 100,000,000, which again is less than 1 in 1,000,000 required by FIPS 140-2. The module enforces a timed access mechanism as follows: For the first five failed attempts (assuming 0 time to process), no timed access is enforced. Upon the sixth attempt, the module enforces a 15- second delay. For the seventh and eight attempts again, no timed access is enforced. Thereafter this cycle repeats, i.e., every third failed attempt, the module enforces a 15-second delay. This would allow the attacker to perform roughly 15 attempts per minute. The probability of a success with multiple consecutive attempts in a one-minute period is 15/(94^8) (or 15/(10^8) in the worst case), which is less than 1/1,000,000. Auditor SNMP User Password/Username or Asymmetric Authentication All passwords must be between 8 and 32 characters. The passwords can consist of alphanumeric values, {a-z, A-Z, 0-9, and special characters}, the characters can thus be chosen from the 94 human readable ASCII characters on an American QWERTY computer keyboard. Thus, the probability of a successful random attempt is 1/94^8 , which is less than 1 in 1,000,000. In the worst-case scenario, if (8) integers are used for an eight-digit password, the probability of randomly guessing the correct sequence is one (1) in 100,000,000 (this calculation is based on the assumption that the typical standard American QWERTY computer keyboard has 10 Integer digits. FIPS 140-2 Security Policy 12 Role Type Of Authentication Authentication Strength The calculation should be 10^8 = 100,000,000). Therefore, the associated probability of a successful random attempt is approximately 1 in 100,000,000, which again is less than 1 in 1,000,000 required by FIPS 140-2. The module enforces a timed access mechanism as follows: For the first five failed attempts (assuming 0 time to process), no timed access is enforced. Upon the sixth attempt, the module enforces a 15- second delay. For the seventh and eight attempts again, no timed access is enforced. Thereafter this cycle repeats, i.e., every third failed attempt, the module enforces a 15-second delay. This would allow the attacker to perform roughly 15 attempts per minute. The probability of a success with multiple consecutive attempts in a one-minute period is 15/(94^8) (or 15/(10^8) in the worst case), which is less than 1/1,000,000. When using RSA based authentication, RSA key pair has modulus size of 2048 bit, thus providing 112 bits of strength. Therefore, an attacker would have a 1 in 2^112 chance of randomly obtaining the key, which is much stronger than the one in a million chance, required by FIPS 140-2. For RSA-based authentication, to exceed a 1 in 100,000 probability of a successful random key guess in one minute, an attacker would have to be capable of approximately 5.19x10^28 attempts per minute. In the worst-case scenario, an operator can make 60 failed attempts per minute. 2.2.3 Services The services that require operators to assume an authorized role (Crypto-Officer or User) are listed in the table below. Please note that the keys and Critical Security Parameters (CSPs) listed below use the following indicators to show the type of access required: • R (Read): The CSP is read • W (Write): The CSP is established, generated, modified, or zeroized • Z (Zeroize): The CSP is zeroized FIPS 140-2 Security Policy 13 Table 4 – Services Service Description Role Key/CSP and Type of Access SSH to external IT device Secure SSH connection between a CM and other FireEye appliances using SSH.

Per RFC 5246, if the module is the party that encounters this condition it will trigger a handshake to establish a new encryption key. Per RFC 5647 the module ensures that if the invocation counter reaches its maximum value 2^64 – 1, the next AES GCM encryption is performed with the invocation counter set to either 0 or 1, with a maximum of 2^64 – 1 encryptions per session.

Note: No parts of the SNMP, SSH, and TLS protocols, other than the KDF, have been tested by the CAVP. 2.5.3 Non-Approved Algorithms Disallowed for Use With FIPS-approved services The same set of services are supported by the module in the non-FIPS mode as in the FIPS mode. In addition to the list of SSH ciphers supported in the FIPS mode (Section 3.4.1), the module also implements the following non-Approved symmetric algorithm that is allowed for use in the non-FIPS mode alone: 1. rijndael-cbc@lysator.liu.se For TLS, the ciphers supported in the FIPS mode (Section 3.4.2) are available except for the following two ciphers: 1.

FIPS 140-2 Security Policy 27 2.7 Self-Tests Self-tests are health checks that ensure that the cryptographic algorithms within the module are operating correctly. The self-tests identified in FIPS 140-2 broadly fall within two categories • Power-On Self-Tests • Conditional Self-Tests 2.7.1 Power-On Self-Tests The cryptographic module performs the following self-tests at Power-On: • Firmware integrity (SHA-256) • HMAC-SHA1 Known Answer Test • HMAC-SHA224 Known Answer Test • HMAC-SHA256 Known Answer Test • HMAC-SHA384 Known Answer Test • HMAC-SHA512 Known Answer Test • AES-128 ECB Encrypt Known Answer Test • AES-128 ECB Decrypt Known Answer Test • AES-GCM-256 Encrypt Known Answer Test • AES-GCM-256 Decrypt Known Answer Test • TDES ECB Encrypt Known Answer Test • TDES ECB Decrypt Known Answer Test • RSA (mod 2048) Sign and Verify Known Answer Tests • ECDSA (P-256) Sign and Verify Known Answer Tests • DRBG (CTR) Known Answer Tests o Generate, Reseed, Instantiate KATs • DRBG (HMAC) Known Answer Tests o Generate, Reseed, Instantiate KATs • DSA Pairwise Consistency Test • Primitive “Z” Known Answer Tests o KAS FFC (dhEphem) o KAS ECC (Ephemeral Unified) 2.7.2 Conditional Self-Tests The cryptographic module performs the following conditional self-tests: • Continuous Random Number Generator Test (CRNGT) for FIPS-approved DRBG • Continuous Random Number Generator (CRNGT) for Entropy Source • Firmware Load Test (2048-bit RSA, SHA-256) • Pairwise Consistency Test (PWCT) for RSA • Pairwise Consistency Test (PWCT) for ECDSA • Pairwise Consistency Test (PWCT) for DSA 2.7.3 Self-Tests Error Handling If any of the identified POSTs fail, the module will not enter an operational state and will instead provide an error message and reboot. If either of the CRNGTs fail, the repeated random FIPS 140-2 Security Policy 28 numbers are discarded and another random number is requested. If either of the PWCTs fail, the key pair or signature is discarded and another key pair or signature is generated. If the Firmware Load Test fails, the new firmware is not loaded. Both during execution of the self-tests and while in an error state, data output is inhibited. FIPS 140-2 Security Policy 29 2.8 Mitigation of Other Attacks The module does not claim to mitigate any other attacks beyond those specified in FIPS 140. FIPS 140-2 Security Policy 30 3. Secure Operation The following steps are required to put the module into the FIPS-approved mode of operation. Prior to performing the steps below, the module is in the non-FIPS mode of operation. The cryptographic officer shall verify that the firmware image to be loaded on the module is a FIPS validated image. If any non-validated firmware image is loaded the module will no longer be a FIPS validated module. Any firmware versions other than version 5.0.4, loaded into the modules are out of the scope of this validation and require a separate FIPS 140-2 validation. 3.1 Modes of Operation The module supports one FIPS Approved mode of operation and a non-Approved mode i.e., a non-FIPS mode of operation. The module must always be zeroized when switching between the FIPS Approved mode of operation and the non-Approved mode of operation and vice versa. Prior to performing the steps outlined below, the module will operate in the non-FIPS mode. All services available in the non-FIPS mode are identical to those in the FIPS approved mode besides key generation services. 3.2 Installation There are no FIPS 140 specific hardware installation steps required. 3.3 Initialization 3.3.1 Default Authentication During initial setup, the CO will be prompted to change the default authentication credentials. These credentials must be changed at this point. 3.3.2 Enable compliance configuration options Perform the following steps to enable FIPS 140-2 configuration options on the webUI. • Enter the CLI configuration mode: hostname > enable hostname # configure terminal • Enable the compliance configuration options on the webUI: compliance options webui enable 3.3.3 Enable FIPS 140-2 compliance There are two methods to enable FIPS 140-2 compliance on the appliance. Compliance may be enabled either through the webUI or through the CLI. Perform the following to enable FIPS 140- 2 compliance through the webUI. • On the Web UI, select the Settings tab. • Select Compliance on the sidebar. • Click Enable FIPS Compliance. • Click Save changes to continue. • Click Reboot Now FIPS 140-2 Security Policy 31 Alternatively, perform the following to enable FIPS 140-2 compliance through the CLI. • Enable the CLI configuration mode: hostname > enable hostname # configure terminal • Bring the system into FIPS 140-2 compliance: hostname (config) # compliance apply standard fips • Save your changes: hostname (config) # write memory • Restart the appliance: hostname (config) # reload • Verify that the appliance is compliant: hostname (config) # show compliance standard fips 3.4 Management 3.4.1 SSH Usage When in FIPS 140-2 compliance mode, only the following algorithms may be used for SSH communications. Note: The module itself restricts access to algorithms. No other algorithms are available. 3.4.1.1 Symmetric Encryption Algorithms: 1. AES_128_CBC 2. AES_128_CTR 3. AES_256_CBC 4. AES_256_CTR 5.

TLS_RSA_WITH_AES_256_CBC_SHA Note: 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. Note: The module is compatible with TLSv1.2 and supports the GCM ciphersuites defined SP 800-52 Rev 1, Section 3.3.1. The module implements nonce management logic that ensures when the nonce_explicit part of the IV exhausts the maximum number of possible values for a given session key a new encryption key is established. 3.4.3 SNMP Usage When in FIPS 140-2 compliance mode, only AES_128_OFB may be used for SNMPv3 communications. Note: The module itself restricts access to algorithms. No other algorithms are available. 3.5 Secure Delivery The product is delivered via commercial carrier (either FedEx or UPS). The product will contain a packing slip with the serial numbers of all shipped devices. The Cryptographic Officer must verify that the hardware serial numbers match the serial numbers listed in the packing slip. Additionally, the Cryptographic Officer must verify that there are no signs of damage/tampering FIPS 140-2 Security Policy 33 within the delivered package. Any sign of damage/tampering must be reported to FireEye for guidance. 3.6 Switching Modes of operation To switch between the FIPS mode and the non-FIPS mode, the “reset factory” command can be used which essentially resets the module to its factory default configuration i.e., the non-FIPS mode. Prior to switching between FIPS mode and non-FIPS mode of operation, the CO must perform the zeroization operation via the “compliance declassify zeroized” command. 3.7 Additional Information For additional information regarding FIPS 140-2 compliance, see the “FireEye FIPS 140-2 and Common Criteria Addendum, Release 1.0.” FIPS 140-2 Security Policy 34 Appendix A: Acronyms This section describes the acronyms used throughout the document.
