Web-Based Manager The FortiGate web-based manager provides GUI based access to the module and is the primary tool for configuring the module. The manager requires a web browser on the management computer and an Ethernet connection between the FortiGate unit and the management computer. A web-browser that supports Transport Layer Security (TLS) 1.0 is required for remote access to the web-based manager when the module is operating in FIPS-CC mode. HTTP access to the web-based manager is not allowed in FIPS-CC mode and is disabled. FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 10 http://docs.fortinet.com/ • Feedback Module Description Figure 6: The FortiGate web-based manager Command Line Interface The FortiGate Command Line Interface (CLI) is a full-featured, text based management tool for the module. The CLI provides access to all of the possible services and configuration options in the module. The CLI uses a console connection or a network (Ethernet) connection between the FortiGate unit and the management computer. The console connection is a direct serial connection. Terminal emulation software is required on the management computer using either method. For network access, a Telnet or SSH client that supports the SSH v2.0 protocol is required (SSH v1.0 is not supported in FIPS- CC mode). Telnet access to the CLI is not allowed in FIPS-CC mode and is disabled. Roles, Services and Authentication Roles When configured in FIPS-CC mode, the module provides the following roles: • Crypto Officer • Network User The Crypto Officer role is initially assigned to the default ‘admin’ operator account. The Crypto Officer role has read-write access to all of the module’s administrative services. The initial Crypto Officer can create additional operator accounts. These additional accounts are assigned the Crypto Officer role and can be assigned a range of read/write or read only access permissions including the ability to create operator accounts.

Network users can make use of the encrypt/decrypt services, but cannot access the module for administrative purposes. The module does not provide a Maintenance role. FIPS Approved Services The following tables detail the types of FIPS approved services available to each role, the types of access for each role and the Keys or CSPs they affect. The role names are abbreviated as follows: Crypto Officer CO User U The access types are abbreviated as follows: Read Access R Write Access W Execute Access E Table 12: Services available to Crypto Officers Service Access Key/CSP authenticate to module WE Operator Password, Diffie-Hellman Key, HTTP/TLS and SSH Server/Host Keys, HTTPS/TLS and SSH Session Authentication Keys, and HTTPS/TLS Session Encryption Keys, RNG Seed, RNG AES Key show system status WE N/A show FIPS-CC mode WE N/A enabled/disabled (console/CLI only) enable FIPS-CC mode of operation WE Configuration Integrity Key (console only) execute factory reset (zeroize keys, E See “Key Zeroization” on page 20 disable FIPS mode, console/CLI only) execute FIPS-CC on-demand self- E Configuration Integrity Key, Firmware tests (console only) Integrity Key add/delete operators and network WE Operator Password, users Network User Password set/reset operator and network user WE Operator Password, passwords Network User Password backup configuration file WE Configuration Encryption Key, Configuration Backup Key read/set/delete/modify module WE N/A configuration enable/disable alternating bypass WE N/A mode FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 12 http://docs.fortinet.com/ • Feedback Module Description Table 12: Services available to Crypto Officers Service Access Key/CSP read/set/delete/modify IPSec/SSL N/A IPSec: IPSec Manual Authentication VPN configuration Key, IPSec Manual Encryption Key, IKE Pre-Shared Key, IKE RSA Key SSL: HTTPS/TLS Server/Host Key, HTTPS/TLS Session Authentication Key, HTTPS/TLS SSH Session Encryption Key read/set/delete/modify HA WE HA Password, configuration HA Encryption Key execute firmware update E Firmware Update Key read log data WE N/A delete log data (console/CLI only) N/A N/A execute system diagnostics WE N/A (console/CLI only) Table 13: Services available to Network Users Service/CSP Access Key/CSP authenticate to module E Network User Password, Diffie-Hellman Key, HTTPS/TLS Server/Host Key, HTTPS/TLS Session Authentication Key, HTTPS/TLS Session Encryption Key, RNG Seed, RNG AES Key IPSec VPN controlled by firewall E Diffie-Hellman Key, IKE and IPSec Keys, policies RNG Seed, RNG AES Key SSL VPN controlled by firewall E Network User Password, Diffie-Hellman policies Key, HTTPS/TLS Server/Host Key, HTTPS/TLS Session Authentication Key, HTTPS/TLS Session Encryption Key, RNG Seed, RNG AES Key Authentication The modules implement identity based authentication. Operators must authenticate with a user-id and password combination to access the modules remotely or locally via the console. Remote operator authentication is done over HTTPS (TLS) or SSH. Password entry is obfuscated using asterisks and the module does not provide feedback on the authentication process - i.e. the module does not indicate if the password or the user/operator account is incorrect for a failed authentication attempt. By default, Network User access to the modules is based on firewall policy and authentication by IP address or fully qualified domain names. Network Users can optionally be forced to authenticate to the modules using a username/password combination to enable use of the IPSec VPN encrypt/decrypt or bypass services. For Network Users invoking the SSL-VPN encrypt/decrypt services, the modules support authentication with a user-id/password combination. Network User authentication is done over HTTPS and does not allow access to the modules for administrative purposes. Note that operator authentication over HTTPS/SSH and Network User authentication over HTTPS are subject to a limit of 3 failed authentication attempts in 1 minute. Operator authentication using the console is not subject to a failed authentication limit, but the number of authentication attempts per minute is limited by the bandwidth available over the serial connection. FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 13 http://docs.fortinet.com/ • Feedback Module Description The minimum password length is 8 characters when in FIPS-CC mode (maximum password length is 32 characters). The password may contain any combination of upper- and lower-case letters, numbers, and printable symbols; allowing for 94 possible characters. The odds of guessing a password are 1 in 94^8 which is significantly lower than one in a million. Recommended procedures to increase the password strength are explained in “FIPS 140-2 Compliant Operation” on page 25. For Network Users invoking the IPSec VPN encrypt/decrypt services, the module acts on behalf of the Network User and negotiates a VPN connection with a remote module. The strength of authentication for IPSec services is based on the authentication method defined in the specific firewall policy: IPSec manual authentication key, IKE pre-shared key or IKE RSA key (RSA certificate). The odds of guessing the authentication key for each IPSec method is: 1 in 1640 for the IPSec Manual Authentication key (based on a 40 digit, hexadecimal • key) 1 in 948 for the IKE Pre-shared Key (based on an 8 character, ASCII printable key) • 1 in 21024 for the IKE RSA Key (based on a 1024bit RSA key size) • Therefore the minimum odds of guessing the authentication key for IPSec is 1 in 948, based on the IKE Pre-shared key. Physical Security The modules meet FIPS 140-2 Security Level 2 requirements by using production grade components and an opaque, sealed enclosure. Access to the enclosure is restricted through the use of tamper-evident seals to secure the overall enclosure. The seals are blue wax/plastic with white lettering that reads “Fortinet Inc. Security Seal”. The tamper seals are not applied at the factory prior to shipping. It is the responsibility of the Crypto Officer to apply the seals before use to ensure full FIPS 140-2 compliance. Once the seals have been applied, the Crypto Officer must develop an inspection schedule to verify that the external enclosure of the module and the tamper seals have not been damaged or tampered with in any way. The Crypto Officer is also responsible for securing and controlling any unused seals. The surfaces should be cleaned with 99% Isopropyl alcohol to remove dirt and oil before applying the seals. Ensure the surface is completely clean and dry before applying the seals. If a seal needs to be re-applied, completely remove the old seal and clean the surface with an adhesive remover before following the instructions for applying a new seal. Additional seals can be requested through your Fortinet sales contact. Reference the following SKUs when ordering: FIPS-SEAL-RED or FIPS-SEAL-BLUE. Specify the type and number of seals required based on the specific module as described below: The FortiGate-200B uses 2 blue seals to secure: • the external enclosure (2 seals, see Figure 7 and Figure 8) The FortiGate-300C uses 2 red seals to secure: • the external enclosure (2 seals, see Figure 9 and Figure 10) The FortiGate-310B use 2seals to secure: • the external enclosure (one seal, see Figure 11) • the blank faceplate covering the AMC slot (one seal, see Figure 12) The FortiGate-600C uses 3 red seals to secure: FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 14 http://docs.fortinet.com/ • Feedback Module Description • the external enclosure, the power supply and the blank faceplate for the redundant power supply (see Figure 13) The FortiGate-620B uses 3 blue seals to secure: • the external enclosure (2 seals, see Figure 14 and Figure 15) • the blank faceplate covering the AMC slot (one seal, see Figure 16) Figure 7: FortiGate-200B external enclosure seal, bottom, left side Figure 8: FortiGate-200B external enclosure seal, bottom, right side FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 15 http://docs.fortinet.com/ • Feedback Module Description Figure 9: FortiGate-300C external enclosure seal, top, left side Figure 10: FortiGate-300C external enclosure seal, top, right side FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 16 http://docs.fortinet.com/ • Feedback Module Description Figure 11: FortiGate-310B external enclosure seal, top, left side Figure 12: FortiGate-310B AMC faceplate seal, front FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 17 http://docs.fortinet.com/ • Feedback Module Description Figure 13: FortiGate-600C seals, bottom, rear Figure 14: FortiGate-620B external enclosure seal, bottom, left side FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 18 http://docs.fortinet.com/ • Feedback Module Description Figure 15: FortiGate-620B external enclosure seal, bottom, right side Figure 16: FortiGate-620B AMC faceplate seal, front Operational Environment The module consists of the combination of the FortiOS operating system and the FortiGate appliances. The FortiOS operating system can only be installed, and run, on a FortiGate appliance. The FortiOS operating system provides a proprietary and non- modifiable operating system. Cryptographic Key Management Random Number Generation The modules use a firmware based, deterministic random number generator that conforms to ANSI X9.31 Appendix A.2.4. FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 19 http://docs.fortinet.com/ • Feedback Module Description The ANSI X9.31 RNG is seeded using a 128-bit AES seed key generated external to the module (estimated entropy 128 bits) and 256 bits of seed (estimated entropy 60 bits) gathered from a random pool filled with 64 bytes of system data and internal resources such as time, memory addresses, kernel ticks, and module identifiers. As the module's ANSI X9.31 RNG implementation only generates random values of size 128 bits, it would take multiple calls to form a 256-bit key. Each time a key is generated with a bit length of more than 128 bits, the key is refreshed with an additional 12 bits of entropy. The total estimated strength for the two calls required to form a 256 bit key would be at theoretical best 200 bits. Key Zeroization The zeroization process must performed under the direct control of the operator. The operator must be present to observe that the zeroization method has completed successfully. All keys except the following are zeroized by executing a factory reset: • ANSI X9.31 RNG AES Key • Firmware Update Key • Firmware Integrity Key • Configuration Integrity Key • Configuration Backup Key • SSH Server/Host Key • HTTPS/TLS Server/Host Key All keys and CSPs are zeroized by formatting the modules’ flash memory storage. To format the flash memory, connect a computer to the modules’ console port and reboot the module. Access the configuration menu by pressing any key when prompted (see example below). Select “F” to format the flash memory (boot device). Press any key to display configuration menu... [G]: Get firmware image from TFTP server. [F]: Format boot device.

The module implements two forms of alternating bypass for VPN traffic: policy based (for IPSec and SSL VPN) and interface based (for IPSec VPN only). Policy Based VPN Firewall policies with an action of IPSec or SSL-VPN mean that the firewall is functioning as a VPN start/end point for the specified source/destination addresses and will encrypt/decrypt traffic according to the policy. Firewall policies with an action of allow mean that the firewall is accepting/sending plaintext data for the specified source/destination addresses. A firewall policy with an action of accept means that the module is operating in a bypass state for that policy. A firewall policy with an action of IPSec or SSL-VPN means that the module is operating in a non-bypass state for that policy. Interface Based VPN Interface based VPN is supported for IPSec only. A virtual interface is created and any traffic routed to the virtual interface is encrypted and sent to the VPN peer. Traffic received from the peer is decrypted. Traffic through the virtual interface is controlled using firewall policies. However, unlike policy based VPN, the action is restricted to Accept or Deny and all traffic controlled by the policy is encrypted/decrypted. When traffic is routed over the non-virtual interfaced, the module is operating in a bypass state. When traffic is routed over the virtual interface, the module is operating in a non- bypass state. In both cases, two independent actions must be taken by a CO to create bypass firewall policies: the CO must create the bypass policy and then specifically enable that policy. Key Archiving The module supports key archiving to a management computer or USB token as part of a module configuration file backup. Operator entered keys are archived as part of the module configuration file. The configuration file is stored in plain text, but keys in the configuration file are either AES encrypted using the Configuration Encryption Key or stored as a keyed hash using HMAC-SHA-1 using the Configuration Backup Key.

Use of these capabilities is optional. The FortiOS IPS has two components: a signature based component for detecting attacks passing through the FortiGate appliance and a local attack detection component that protects the firewall from direct attacks. Functionally, signatures are similar to virus definitions, with each signature designed to detect a particular type of attack. The IPS signatures are updated through the FortiGuard IPS service. The IPS engine can also be updated through the FortiGuard IPS service.

FortiOS antivirus protection also controls the blocking of oversized files and supports blocking by file extension. Virus signatures are updated through the FortiGuard antivirus service. The antivirus engine can also be updated through the FortiGuard antivirus service. FortiOS antispam protection tags (SMTP, IMAP, POP3) or discards (SMTP only) email messages determined to be spam. Multiple spam detection methods are supported including the FortiGuard managed antispam service. FortiOS web filtering can be configured to provide web (HTTP) content filtering. FortiOS web filtering uses methods such as banned words, address block/exempt lists, and the FortiGuard managed content service. Whenever a IPS, antivirus, antispam or filtering event occurs, the modules can record the event in the log and/or send an alert email to an operator. For complete information refer to the FortiGate Installation Guide for the specific module in question, the FortiGate Administration Guide and the FortiGate IPS Guide. FIPS 140-2 Compliant Operation FIPS 140-2 compliant operation requires both that you use the module in its FIPS-CC mode of operation and that you follow secure procedures for installation and operation of the FortiGate unit. You must ensure that: • The FortiGate unit is configured in the FIPS-CC mode of operation. • The FortiGate unit is installed in a secure physical location. • Physical access to the FortiGate unit is restricted to authorized operators. • Administrative passwords are at least 8 characters long. • Administrative passwords are changed regularly. • Administrator account passwords must have the following characteristics: • One (or more) of the characters should be capitalized • One (or more) of the characters should be numeric • One (or more) of the characters should be non alpha-numeric (e.g. punctuation mark) • Administration of the module is permitted using only validated administrative methods. These are: • Console connection • Web-based manager via HTTPS • Command line interface (CLI) access via SSH • Diffie-Hellman groups of less than less than 1024 bits (Group 5) are not used. • Client side RSA certificates must use 1024 bit or greater key sizes. • LDAP based authentication must use secure LDAP (LDAPS). • Only approved and allowed algorithms are used (see “Algorithms” on page 21). • The tamper evident seals are applied (see “Physical Security” on page 14).

NAT/Route mode applies security features between two or more different networks (for example, between a private network and the Internet). Transparent mode applies security features at any point in a network. The current operation mode is displayed on the web- based manager Status page and in the output of the get system status CLI command. Enabling FIPS-CC mode To enable the FIPS 140-2 compliant mode of operation, the operator must execute the following command from the Local Console: config system fips set status enable end The Operator is required to supply a password for the admin account which will be assigned to the Crypto Officer role. The supplied password must be at least 8 characters long and correctly verified before the system will restart in FIPS-CC mode. Upon restart, the module will execute self-tests to ensure the correct initialization of the module’s cryptographic functions. After restarting, the Crypto Officer can confirm that the module is running in FIPS-CC mode by executing the following command from the CLI: get system status If the module is running in FIPS-CC mode, the system status output will display the line: FIPS-CC mode: enable Note that enabling/disabling the FIPS-CC mode of operation will automatically invoke the key zeroization service. The key zeroization is performed immediately after FIPS-CC mode is enabled/disabled. Self-Tests The module executes the following self-tests during startup and initialization: • Firmware integrity test using RSA signatures • Configuration/VPN bypass test using HMAC SHA-1 • Triple-DES, CBC mode, encrypt known answer test • Triple-DES, CBC mode, decrypt known answer test • AES, CBC mode, encrypt known answer test • AES, CBC mode, decrypt known answer test • HMAC SHA-1 known answer test • SHA-1 known answer test (test as part of HMAC SHA-1 known answer test) • HMAC SHA-256 known answer test • SHA-256 known answer test (test as part of HMAC SHA-256 known answer test) • RSA signature generation known answer test • RSA signature verification known answer test • RNG known answer test FortiGate-200B/300C/310B/600C/620B FIPS 140-2 Security Policy 01-436-176386-20120719 26 http://docs.fortinet.com/ • Feedback Non-FIPS Approved Services The results of the startup self-tests are displayed on the console during the startup process. The startup self-tests can also be initiated on demand using the CLI command execute fips kat all (to initiate all self-tests) or execute fips kat (to initiate a specific self-test). When the self-tests are run, each implementation of an algorithm is tested - e.g. when the AES self-test is run, all AES implementations are tested. The module executes the following conditional tests when the related service is invoked: • Continuous RNG test • Continuous NDRNG test • RSA pairwise consistency test • Configuration/VPN bypass test using HMAC SHA-1 • Firmware load test using RSA signatures If any of the self-tests or conditional tests fail, the module enters an error state as shown by the console output below: Self-tests failed Entering error mode... The system is going down NOW !! The system is halted. All data output and cryptographic services are inhibited in the error state. Non-FIPS Approved Services The module also provides the following non-FIPS approved services: • Configuration backups using password protection • LLTP and PPTP VPN • Paired Bypass network interfaces (WAN1/Port1 and WAN2/Port2) If the above services are used, the module is not considered to be operating in the FIPS approved mode of operation.
