ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 2 ProxySG 900 Series 2.1 Overview The foundation of Blue Coat’s application delivery infrastructure, the Blue Coat ProxySG 900 Series appliances establish points of control that accelerate and secure business applications for users across the distributed organization. The ProxySG 900 Series appliances serve as an Internet proxy and wide area network (WAN) optimizer. The purpose of the appliances is to provide a layer of security between an Internal and External Network (typically an office network and the Internet), and to provide acceleration and compression of transmitted data. As the world’s leading proxy appliance, the Blue Coat SG900 is a powerful yet flexible tool for improving both application performance and security, removing the need for compromise:  Performance – Blue Coat’s patented “MACH5” acceleration technology combines five different capabilities onto one box. Together, they optimize application performance and help ensure delivery of critical applications. User and application fluent, MACH5 improves the user experience no matter where the application is located, internally or externally on the Internet.  Security – Blue Coat’s industry leading security architecture addresses a wide range of requirements, including filtering Web content, preventing spyware and other malicious mobile code, scanning for viruses, inspecting encrypted Secure Sockets Layer (SSL) traffic, and controlling instant messaging (IM), Voice-over-IP (VoIP), peer-to-peer (P2P), and streaming traffic.  Control – Blue Coat’s patented Policy Processing Engine empowers administrators to make intelligent decisions. Using a wide range of attributes such as user, application, content and others, organizations can effectively align security and performance policies with corporate priorities. See Figure 1 below for a typical deployment scenario for the ProxySG 900 Series appliances. Figure 1 Typical Deployment of a ProxySG 900 Series Appliance The security provided by the SG900can be used to control, protect, and monitor the Internal Network’s use of controlled protocols on the External Network. The SG900 appliances offer a choice of two “editions” via licensing: MACH5 and Proxy. The MACH5 edition appliances have some proxy features disabled (as indicated below). The controlled protocols implemented in the evaluated configuration are: Blue Coat ProxySG 900 Series Page 5 of 40 © 2014 Blue Coat Systems, Inc.

The policy may include authentication, authorization, content filtering, and auditing. In addition, the SG900 provides optimization of data transfer between SG900 nodes on a WAN. Optimization is achieved by enforcing a configurable policy (WAN Optimization SFP) on traffic traversing the WAN. Additionally, the SG900 offers network traffic acceleration by using hardware implementations of cryptographic services provided by on-board hardware accelerator cards (HAC) produced by Cavium Networks. The SG900 is validated at the following FIPS 140-2 Section levels in Table 2.

There are two authorized roles in the module that an operator may assume: a Crypto-Officer (CO) role and a User role. Before accessing the modules for any administrative services, COs and Users must authenticate to the module according to the methods specified in Table 11. The modules offer two management interfaces:  Command Line Interface (CLI) – accessible locally via the serial port (provides access to the Setup Console portion of the CLI which requires the additional “Setup” password to gain access) or remotely using SSH. This interface is used for management of the modules. This interface must be accessed locally via the serial port to perform the initial module configurations (IP address, DNS server, gateway, and subnet mask) and placing the modules into the Approved mode. Management of the module may take place via SSH or locally via the serial port. Authentication is required before any functionality will be available through the CLI.  Management Console – a graphical user interface accessible remotely with a web browser that supports TLS10. This interface is used for management of the modules. Authentication is required before any functionality will be available through the Management Console. When managing the module over the CLI, COs and Users both log into the modules with administrator accounts entering the “standard”, or “unprivileged” mode on the SG900. Unlike Users, COs have the ability to enter the “enabled”, or “privileged” mode after initial authentication to the CLI by supplying the “enabled” mode password. Additionally, COs can only enter the “configuration” mode from the “enabled” mode via the CLI, which grants privileges to make configuration level changes. Going from the “enabled” mode to the “configuration” mode does not require additional credentials. The details of these modes of operation are found below in Table 8. TLS – Transport Layer Security 10 Blue Coat ProxySG 900 Series Page 11 of 40 © 2014 Blue Coat Systems, Inc. This document may be freely reproduced and distributed whole and intact including this copyright notice. ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 Table 8 FIPS and SG900 Roles FIPS Roles SG900 Roles and Privileges CO The CO is an administrator of the module that has been granted “enabled” mode access while using the CLI and “read/write” access while using the Management Console. When the CO is using the CLI, and while in the “enabled” mode of operation, COs may put the module in its Approved mode, reset to the factory state (local serial port only) and query if the module is in Approved mode. In addition, COs may do all the services available to Users while not in “enabled” mode. Once the CO has entered the “enabled” mode, the CO may then enter the “configuration” mode via the CLI. The “configuration” mode provides the CO management capabilities to perform tasks such as account management and key management. When the CO is administering the module over the Management Console, they can perform all the same services available in CLI (equivalent to being in the “configuration” mode in the CLI) except the CO is unable to put the module into Approved mode. The CO may monitor the health and status of the modules using SNMPv3. SNMPv3 privacy and authentication keys are assigned to a CO and are not tied to the CO’s CLI and Management Console credentials. User The User is an administrator of the module that operates only in the “standard” or “unprivileged” mode and has not been granted access to the “enabled” mode in the CLI and has been given “read-only” privileges when using the Management Console. The User will access the CLI and Management Console interfaces for management of the module. When the User is administering the module over the Management Console, they perform all the same services available in CLI (“standard” mode only services). The User may monitor the health and status of the modules using SNMPv3. SNMPv3 privacy and authentication keys are assigned to a User and are not tied to the User’s CLI and Management Console credentials. Descriptions of the services available to a Crypto Officer and User are described below in Table 9 and Table 10 respectively. For each service listed below, COs and Users are assumed to already have authenticated prior to attempting to execute the service. Please note that the keys and CSPs listed in the table indicate the type of access required using the following notation:  R – Read: The plaintext CSP is read by the service.  W – Write: The CSP is established, generated, modified, or zeroized by the service.  X – Execute: The CSP is used within an Approved or Allowed security function or authentication mechanism. 2.4.1 Crypto-Officer Role Descriptions of the services available to the Crypto-Officer role are provided in the table below.

For more information on the non security relevant services of the module, please refer to the Blue Coat® Systems SGOS Administration Guide. 2.4.4 Authentication Mechanism COs and Users must authenticate using a user ID and password, SSH client key (SSH only), or certificates associated with the correct protocol in order to set up the secure session. Secure sessions that authenticate for User services have no interface available to access other services (i.e. Crypto Officer services). Each CO or User SSH session remains active (logged in) and secured until the operator logs out. Each CO and User Management Console session remains active until the operator logs out or inactivity for a configurable amount of time has elapsed. Modules used by the United States Department of Defense (DoD) must meet Homeland Security Presidential Directive (HSPD)-12 requirements regarding the use of FIPS 201 validated Common Access Card (CAC) authentication for COs and Users connecting to management functionality of the module. Additionally, other agencies may require FIPS 201 validated PIV11 II card authentication. 11 PIV – Personal Identity Verification II Blue Coat ProxySG 900 Series Page 15 of 40 © 2014 Blue Coat Systems, Inc.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 When the module is configured to use CAC authentication, the module will implement specially configured CPL during administrator authentication in order to facilitate TLS mutual authentication. This is accomplished by modifying the HTTPS-Console service so that it can be configured to validate a client certificate against a chosen certificate authority (CA) list. CAC authentication will take place against a Certificate realm, and CO and User authorization takes place against an LDAP realm. The authentication procedure leverages 3rd party middleware on the management workstation in order to facilitate two factor authentication of the user to their CAC using a Personal Identification Number (PIN). This process enables the module to retrieve the X.509 certificate from the microprocessor smart card. The process is as follows: 1. On the management workstation the CO or User opens a browser and establishes a clear-text HTTP connection with the module. 2. Using CPL similar to the VPM NotifyUser action, the CO or User is presented with a DoD warning banner which they must positively acknowledge and accept. 3. NotifyUser redirects the browser to an HTTPS connection with the module that requires mutual authentication. This is made possible by CPL that puts the module in reverse-proxy mode at this point. 4. The TLS handshakes begin. The reverse-proxy service on the module requires a certificate to complete the handshake (i.e. the verify-peer setting has been enabled in the reverse-proxy service). 5. The browser presents the CO or User with a dialog box prompting which certificate to select. 6. The CO or User selects the X.509 certificate on the CAC. 7. The middleware on the management workstation prompts the CO or User for the PIN to unlock the certificate. The CO or User enters the PIN and the certificate is transmitted to the module. 8. The module authenticates the certificate against the CA list that has been configured on the reverse proxy service using local CRLs and OCSP to check for certificate revocation. 9. The CO or User reviews and accepts the certificate issued to the web browser by the module. A mutually authenticated TLS session is now in use. 10. The module extracts the subject name (of the CO or User) from the subjectAltNames extension of the X.509 certificate according to configuration of the certificate realms, Within the subjectAltNames extension is the CO or User’s userPrincipleName (UPN) (When PIV cards are used in place of CACs, the CommonName (CN) field is extracted from the certificate instead). The UPN/CN is what ties the CAC identity to the Principle Name (PN) field of a CO or User record in Active Directory (AD), the LDAP server. 11. The certificate realm is configured to use an LDAP realm for authorization. The LDAP user is determined by LDAP search using the following filter: (userPrincipleName=$(user.name)). The CO or User is granted access to the Management Console if the UPN/CN is found in the LDAP directory. The exchanges with the LDAP server are secured using TLS. Conditions like group= and ldap.attribute may also be used to authorize the CO or User and to specify if the CO or User should have read-only or read-write access. The authentication mechanisms used in the module are listed below in Table 11. Blue Coat ProxySG 900 Series Page 16 of 40 © 2014 Blue Coat Systems, Inc.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 Table 11 Authentication Mechanisms Used by the Module Role Type of Authentication Authentication Strength Crypto-Officer Password The modules support password authentication internally. For password authentication done by the modules, passwords are required to be at least 8 characters in length and maximum of 64 bytes (number of characters is dependent on the character set used by system). An 8-character password allowing all printable American Standard Code for Information Interchange (ASCII) characters (95) with repetition equates to a 1: (958), or 1: 6,634,204,312,890,625 chance of false acceptance. The Crypto-Officer may connect locally using the serial port or remotely after establishing a TLS or SSH session. Password (“Enabled” Mode) The modules support password authentication internally. For password authentication done by the modules, passwords are required to be at least 8 characters in length and maximum of 64 bytes (number of characters is dependent on the character set used by system). An 8-character password allowing all printable American Standard Code for Information Interchange (ASCII) characters (95) with repetition equates to a 1: (958), or 1: 6,634,204,312,890,625 chance of false acceptance. This password is entered by the Crypto- Officer to enter the “enabled” mode; this is entered locally through the serial port or remotely after establishing an SSH session. Password (“Setup”) The modules support password authentication internally. For password authentication done by the modules, passwords are required to be at least 4 characters in length and maximum of 64 bytes (number of characters is dependent on the character set used by system). A 4-character password allowing all printable American Standard Code for Information Interchange (ASCII) characters (95) with repetition equates to a 1: (954), or 1: 81,450,625 chance of false acceptance. This password is entered by the Crypto-Officer and is required when using the serial port to access the Setup Console portion of the CLI. Public keys The module supports using RSA keys for authentication of Crypto-Officers during TLS (when CAC authentication is configured with a local Certificate Realm) or SSH. Using conservative estimates and equating a 2048-bit RSA key to a 112-bit symmetric key, the probability for a random attempt to succeed is 1:2112 or 1: 5.19 x 1033.

There are only a limited set of vent holes provided in the case, and these holes obscure the view of the internal components of the module. Tamper-evident labels are applied to the case to provide physical evidence of attempts to remove the case of the module. The Crypto-Officer is responsible for the placement of tamper-evident labels and baffles and guidance can be found in section 3.1.1.2. The labels and baffles are part of the FIPS Security Kit (Part Number: 085- 02742). All of the module’s components are production grade. The SG900 was tested and found conformant to the EMI/EMC requirements specified by 47 Code of Federal Regulations, Part 15, Subpart B, Unintentional Radiators, Digital Devices, Class A (i.e., for business use). 2.6 Operational Environment The operational environment requirements do not apply to the SG900. The module does not provide a general purpose operating system nor does it allow operators the ability to load untrusted firmware. The operating system run by the cryptographic module is referred to as Secure Gateway Operating System (SGOS). SGOS is a proprietary real-time embedded operating system. 2.7 Cryptographic Key Management The module implements the FIPS-Approved algorithms listed in Table 12 below.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 2.8 Self-Tests If any of the hardware accelerator cards self-tests fail, then the module forces the corresponding card to enter an error state, logs the error to a file, and shuts down the card. The modules will only use the cryptographic implementations found in the firmware. If any of the firmware self-tests fail, an error is printed to the CLI (when being accessed via the serial port). When this error occurs, the modules halt operation and provide no functionality. The only way to clear the error and resume normal operation is for the Crypto-Officer to reboot the modules. The status output provided below is shown only over the CLI (when being accessed via the serial port). ********************** SYSTEM ERROR *********************** The SG Appliance has failed the FIPS Self test.

If the hardware accelerator card self-tests fail, all algorithm execution will occur exclusively in the firmware implementation. No data output occurs via the data output interface until all power-up self tests including the hardware accelerator card power-up self-tests have completed.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 2.8.2 Conditional Self-Tests The SG900 performs the conditional self-tests in Table 14 (only on its firmware implementation of OpenSSL). Table 14 SG900 Conditional Self-Tests Conditional Self-Test Occurrence Firmware load test (RSA sign/verify) test This test is run when the firmware is loaded. An RSA digital signature verification is performed over the firmware. If the verification succeeds, the test succeeds; otherwise it fails. RSA pairwise consistency test This test is run upon generation of an RSA key pair for key transport. The public key is used to wrap a block of data, and the resultant ciphertext is compared with the original data. If they are the same, the test fails. If they differ, then the private key is used to unwrap the ciphertext, and the resultant plaintext is compared to the original data. If they are the same, the test passes. Otherwise, it is failed. Continuous RNG Test (CRNGT) for the This test is run upon generation of FIPS-Approved DRBG random data by the DRBG to detect failure to a constant value. CRNGT for the non-Approved NDRNG This test is run when the DRBG is requesting entropy. When entropy has been gathered, this test compares the collected entropy with the previously collected entropy. If they are equal, the test fails. If they differ, the newly collected entropy is returned to be used by the DRBG. 2.8.3 Critical Function Tests The SG900 performs the SP800-90A DRBG Critical Function tests in Table 15 (only on its firmware implementation of OpenSSL).

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 Table 15 List of Critical Function Tests Conditional Test Occurrence SP 800-90A DRBG Instantiate Test Done before the instantiation of a new DRBG. The DRBG instantiation algorithm is sent fixed values of entropy, nonce, and personalization string. The output is compared with the value that was expected. If the values match, the test passes. Otherwise, it fails. Error testing is done by forcing an error upon the algorithm. If the algorithm handles the error as expected, the test passes. Otherwise, it fails SP 800-90A DRBG Generate Test Done before the first use of the DRBG. The DRBG Generate function tests both the Instantiate and Reseed algorithms. KATs are performed for each security strength supported and for each prediction resistance (if supported). The number of bits requested, additional input (if supported), working internal state, are supplied to the Generate function. If the values used during the test produce the expected results and the errors are handled as expected, the test passes. Otherwise, it fails. SP 800-90A DRBG Reseed Test Done before reseeding the DRBG instantiation function (w/o prediction resistance) or before the generation of a new random number (w/ prediction resistance). The DRBG reseed algorithm is sent fixed values of entropy and the internal state value, V. The output is compared with the value that was expected. If the values match, the test passes. Otherwise, it fails. Error testing is done by forcing an error upon the algorithm. If the algorithm handles the error as expected, the test passes. Otherwise, it fails SP 800-90A DRBG Uninstantiate Test This test is performed whenever the Instantiate, Generate, or Reseed tests are executed. It demonstrates that error handling is performed correctly and zeroizes the internal state 2.9 Mitigation of Other Attacks This section is not applicable. The module does not claim to mitigate any attacks beyond the FIPS 140-2 Level 2 requirements for this validation. Blue Coat ProxySG 900 Series Page 27 of 40 © 2014 Blue Coat Systems, Inc.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 3 Secure Operation The SG900 meets Level 2 requirements for FIPS 140-2. The sections below describe how to place and keep the module in FIPS-Approved mode of operation. 3.1 Initial Setup Before powering-up the module, the CO must ensure that the required tamper-evident labels (included in the FIPS security kit) are correctly applied to the enclosure. The FIPS security kit (Part Number: 085- 02742) consists of the following items as shown below in Figure 4. Figure 4 FIPS Security Kit Contents Note: Two (2) long labels and five (5) short labels are required to secure the appliance. Additional labels are included for reapplication purposes. A hard copy of the guidance found below in section 3.1.1.2 is also included in the kit in a document titled “ProxySG 900 Series, FIPS Compliance Guide: Tamper Evident Panel and Label Installation, Rev B.0”. 3.1.1 Label and Baffle Installation Instructions The Crypto-Officer is responsible for installing the baffle (security panel) and applying the tamper-evident labels at the client’s deployment site 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. If the Crypto-Officer detects evidence of tampering or damage to the labels, the Crypto-Officer must return to the module to the uninitialized factory state, remove and reapply all labels per section 3.1.1.2, and must complete the first- time configuration in order to operate in its FIPS-Approved mode as detailed in section 3.2.1. The Crypto- Officer is responsible for securing and having control at all times of any unused seals. The Crypto-Officer is responsible for the direct control and observation of any changes to the module such as reconfigurations where the tamper-evident seals or security appliances are removed or installed to ensure the security of the module is maintained during such changes and the module is returned to a FIPS Approved state. Crypto-Officers must adhere to the following when applying the tamper-evident labels: Blue Coat ProxySG 900 Series Page 28 of 40 © 2014 Blue Coat Systems, Inc. This document may be freely reproduced and distributed whole and intact including this copyright notice. ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014  The minimum temperature of the environment must be 35-degrees Fahrenheit. After application, the labels’ acceptable temperature in the operational environment is -5-degrees to 158-degrees Fahrenheit.  Do not touch the adhesive side of the label. This disrupts the integrity of the adhesive. If a label is removed from a surface, the hologram image is destroyed and the label leaves a patterned silicone adhesive as evidence. If you accidently touch the adhesive side, discard that label and apply another one.  Label application tips: o Apply skin moisturizer on your fingers before handling. o Use a rubber finger tip to partially remove the label from its backing.  After applying the labels, allow at least 24 hours for the label adhesive to cure. 3.1.1.1 Baffle Installation The baffles for the rear of the appliance are designed to prevent unauthorized access to key system components by shielding the rear ventilation outlets. Figure 5 below shows the security panel installed in a SG900 appliance equipped with two power supply units. Figure 5 Rear Security Panel Installed 1. Align the security panel mounting points against the screw locations shown below in Figure 6 and secure with nine (9) flat-head screws. Be aware the FIPS kit includes (3) additional screws, in case some are misplaced or lost during installation. Blue Coat ProxySG 900 Series Page 29 of 40 © 2014 Blue Coat Systems, Inc.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 Figure 6 Rear Security Panel Installation 3.1.1.2 Label Installation The tamper-evident labels are applied over key areas of the chassis to provide tamper-evident security. If the labels are removed after being affixed to a surface, the image self-destructs and leaves a text pattern on the label. Figure 7 below illustrates the tamper-evident features of the label. Figure 7 Label Showing Tamper Evidence 1. Use alcohol swabs to clean the label location surface using Isopropyl Alcohol (99%); this ensures complete adhesion. Verify that all the surfaces are dry before applying the labels. 2. Set the appliance on a flat, slip-proof work space and make sure you have access to all sides of the appliance. 3. Apply two (2) labels over the rear security panel. These labels extend over the bottom edge of the appliance when properly applied because the extraneous material must not cover the vents or ports. A. Apply one (1) short label vertically in the non-vented surface between the serial port and appliance serial number shown by Step 3A in Figure 8 below. Make sure the remaining label material crosses over the bottom edge of the appliance. B. Apply one (1) short label vertically over the lower-right (when viewed from the rear) corner of the security panel shown by Step 3B in Figure 8 below. Make sure the security label covers the entire screw head, the bottom two rows, across two columns of vents; the remaining label material crosses over the bottom edge of the appliance.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 3.2 Secure Management 3.2.1 Initialization The module is delivered in an uninitialized factory state, and requires minimal first-time configuration in order to operate in its FIPS-Approved mode and be accessed by a web browser. Physical access to the module shall be limited to the Crypto-Officer, and the CO shall be responsible for putting the module into the Approved mode. The process of establishing the initial configuration via a secure serial port is described below. Connect a serial cable to a serial port on a PC and to the module’s serial port. Open a terminal 1. emulator (such as HyperTerminal) on the PC, and connect to the serial port to which you attached the cable. Create and name a new connection (either a COM or TCP/IP), using the port parameters provided in Table 16. Table 16 RS-232 Parameters RS-232C Parameter Parameter Setting Baud rate 9600 bps Data bits 8 Parity None Stop bits 1 Flow control None 2. Power on the module and wait for the system to finish booting. Press three times. When the “Welcome to the SG Appliance Setup Console” prompt appears, 3. the system is ready for the first-time network configuration. 4. Set up the first time configuration by entering the interface number, IP address, IP subnet mask, IP gateway, DNS server parameters, username, and password. Press to confirm the configuration when the “Successful Configuration Setup” prompt 5. appears. 6. Repeat step 3. 7. Selection option #1 for the Command Line Interface. This option takes you immediately to the Admin prompt. The Crypto-Officer shall enter the “enabled” mode on the CLI by typing the ‘enable’ command 8. followed by the ‘enable’ password.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 The prompt will change from ‘>’ to ‘#’ signifying the Crypto-Officer is in the ‘enabled’ mode. Type 9. the command ‘fips-mode enable.’ When prompted for confirmation, elect ‘y’ to confirm. Once the reinitialization is complete, the module will display the prompt “The system is in FIPS mode.”  NOTE 1: The entry of the “fips-mode enable” command causes the device to power cycle, zeroizing the Master Appliance Key and returning the configuration values set in steps 1 and 2 to their factory state.  NOTE 2: This command is only accepted via the CLI when accessed over the serial port. 10. Wait for the system to finish rebooting. Repeat step 3. 11. Repeat step 4. 12. The module will prompt for the ‘enabled’ mode password: You must configure the console user account now. Enter console username: Enter console password: Enter enable password: 13. Configure the setup password to secure the serial port which must be configured while in FIPS mode. The module will prompt the following: The serial port must be secured and a setup password must be configured. Enter setup password: 14. The module will prompt to restrict workstation access. Choose “Yes” or “No.” 15. Finally, select the licensing mode. The module will prompt with the following options: M)ACH5 Edition P)roxy Edition Upon completion of these initialization steps, the module is considered to be operating in its Approved mode of operation. 3.2.2 Management The Crypto-Officer is able to monitor and configure the module via the web interface (HTTPS over TLS) and the CLI (serial port or SSH). The Crypto-Officer should monitor the module’s status regularly. If any irregular activity is noticed or the module is consistently reporting errors, customers should consult Blue Coat Systems Blue Touch Online (BTO) and the administrative guidance documents to resolve the issues. If the problems cannot be resolved through these resources, Blue Coat Systems customer support should be contacted. The CO must ensure that localized keys used for SNMPv3 authentication and privacy match the key type requirements specified in Table 13. Key sizes less than what is specified shall not be used. The CO password and “enabled” mode password must be at least 8 characters in length. The “Setup” password must be at least 4 characters in length.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 When creating or importing key pairs, such as during the restoration of an archived SG900 configuration, the CO must ensure that the “Do not show key pair” option is selected in the Management Console as shown in Figure 12, or the “no-show” argument is passed over the CLI as shown in Figure 13. Please see Section E: Preparing Archives for Restoration on New Devices in the Blue Coat Systems SGOS Administration Guide, Version 6.5 for further reference. Figure 12 Keyring Creation Management Console Dialogue Box Figure 13 Keyring Creation CLI Commands 3.2.3 Zeroization The CO can return the module to its factory state by entering the “enabled” mode on the CLI, followed by the “fips-mode disable” command. This command will automatically reboot the module and zeroize the MAK. The RSA private key, Crypto-Officer password, User password, “Enabled” mode password, “Setup” password, SNMP Privacy key, and the SNMP Authentication key are all stored encrypted by the MAK. Once the MAK is zeroized, decryption involving the MAK becomes impossible, making these CSPs unobtainable by an attacker. In addition, rebooting the module causes all temporary keys stored in volatile memory (SSH Session key, TLS session key, DRBG entropy values, and NDRNG entropy values) to be zeroized. The Crypto-Officer must wait until the module has successfully rebooted in order to verify that zeroization has completed. 3.3 User Guidance The User is only able to access the module remotely via SSH (CLI) or HTTPS (Management Console). The User must change his or her password at the initial login. The User must be diligent to also pick strong Blue Coat ProxySG 900 Series Page 35 of 40 © 2014 Blue Coat Systems, Inc.

ProxySG 900 Series Security Policy, Version 0.7 May 29, 2014 passwords (alphanumeric with minimum 8 characters) that will not be easily guessed, and must not reveal their password to anyone. Additionally, the User should be careful to protect any secret/private keys in their possession, such as TLS or SSH session keys. The User should report to the Crypto Officer if any irregular activity is noticed. 3.4 Non-Approved Mode When initialized and configured according to the Crypto-Officer guidance in this Security Policy, the module does not support a non-Approved mode of operation.
