Network access control mechanisms interoperate to prevent unauthorized access and to enforce the organization's security policy. Access to the network must be categorized as administrator, user, or guest so the appropriate authorization can be assigned to the user requesting access to the network or a network device. Authorization requires an individual account identifier that has been approved, assigned, and configured on an authentication server. Authentication of user identities is accomplished through the use of passwords, tokens, biometrics, or in the case of multi-factor authentication, some combination thereof. Lack of authentication enables anyone to gain access to the network or possibly a network device providing opportunity for intruders to compromise resources within the network infrastructure.Information Assurance Officer
Checks: C-3456r6_chk

Review the network devices configuration to determine if administrative access to the device requires some form of authentication--at a minimum a password is required. If passwords aren't used to administrative access to the device, this is a finding.

All network devices must present a DoD-approved warning banner prior to a system administrator logging on. The banner should warn any unauthorized user not to proceed. It also should provide clear and unequivocal notice to both authorized and unauthorized personnel that access to the device is subject to monitoring to detect unauthorized usage. Failure to display the required logon warning banner prior to logon attempts will limit DoD's ability to prosecute unauthorized access and also presents the potential to give rise to criminal and civil liability for systems administrators and information systems managers. In addition, DISA's ability to monitor the device's usage is limited unless a proper warning banner is displayed. DoD CIO has issued new, mandatory policy standardizing the wording of "notice and consent" banners and matching user agreements for all Secret and below DoD information systems, including stand-alone systems by releasing DoD CIO Memo, "Policy on Use of Department of Defense (DoD) Information Systems Standard Consent Banner and User Agreement", dated 9 May 2008. The banner is mandatory and deviations are not permitted except as authorized in writing by the Deputy Assistant Secretary of Defense for Information and Identity Assurance. Implementation of this banner verbiage is further directed to all DoD components for all DoD assets via USCYBERCOM CTO 08-008A.Information Assurance Officer

Verify either Option A or Option B (for systems with character limitations) of the Standard Mandatory DoD Notice and Consent Banner is displayed at logon. The required banner verbiage follows and must be displayed verbatim: Option A You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details. Option B If the system is incapable of displaying the required banner verbiage due to its size, a smaller banner must be used. The mandatory verbiage follows: "I've read & consent to terms in IS user agreem't." If the device configuration does not have a logon banner as stated above, this is a finding.

Fix: F-3038r8_fix

Configure all management interfaces to the network device to display the DoD-mandated warning banner verbiage at logon regardless of the means of connection or communication. The required banner verbiage that must be displayed verbatim is as follows: Option A You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only.

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled between the managed network device and a PC or terminal server when the later has been left unattended. In addition quickly terminating an idle session will also free up resources committed by the managed network device as well as reduce the risk of a management session from being hijacked. Setting the timeout of the session to 10 minutes or less increases the level of protection afforded critical network components.Information Assurance Officer

Numerous vulnerabilities exist with SNMP; therefore, without unique SNMP community names, the risk of compromise is dramatically increased. This is especially true with vendors default community names which are widely known by hackers and other networking experts. If a hacker gains access to these devices and can easily guess the name, this could result in denial of service, interception of sensitive information, or other destructive actions.Information Assurance Officer
Checks: C-3825r7_chk

Review the SNMP configuration of all managed nodes to ensure different community names (V1/2) or groups/users (V3) are configured for read-only and read-write access. If unique community strings or accounts are not used for SNMP peers, this is a finding.

Fix: F-3068r4_fix

Configure the SNMP community strings on the network device and change them from the default values. SNMP community strings and user passwords must be unique and not match any other network device passwords. Different community strings (V1/2) or groups (V3) must be configured for various levels of read and write access.

The use of POTS lines to modems connecting to network devices provides clear text of authentication traffic over commercial circuits that could be captured and used to compromise the network. Additional war dial attacks on the device could degrade the device and the production network. Secured modem devices must be able to authenticate users and must negotiate a key exchange before full encryption takes place. The modem will provide full encryption capability (Triple DES) or stronger. The technician who manages these devices will be authenticated using a key fob and granted access to the appropriate maintenance port, thus the technician will gain access to the managed device (router, switch, etc.). The token provides a method of strong (two-factor) user authentication. The token works in conjunction with a server to generate one-time user passwords that will change values at second intervals. The user must know a personal identification number (PIN) and possess the token to be allowed access to the device.Information Assurance Officer

Detailed Policy Requirements: The site WMAN systems will implement strong authentication from the User or WMAN subscriber device to WMAN network. For tactical WMAN systems or commercial WMAN systems operated in a tactical environment, two factor authentication is required, at a minimum. Note: Examples of two-factor authentication are password with biometrics or CAC with PIN. In cases where there are no available WMAN technology solutions that meets this requirement, the local DAA may grant an exception to this requirement until such time as a WMAN product is available that meets this requirement. The exception must be documented during the system DIACAP and in the site SSAA/SSP. At a minimum, the system must meet the authentication requirements of non-tactical WMAN systems. -For tactical or commercial WMAN systems operated in a non-tactical environment, this check does not apply: Checks WIR0315-02 and WIR0315-02 apply. Check Procedures: - Determine if the WMAN system is used in a tactical or non-tactical environment. - Review the WMAN system product documentation (specification sheet, network administration manual, installation manual, etc.) to determine what authentication mechanism is supported between the user/subscriber device and WMAN network. - Review the authentication configuration configured on the WMAN access point. (Have the system administrator and user show you the setting.) - Verify “User or WMAN subscriber device to WMAN network” authentication meets requirements. --For WMAN systems operated in a tactical environment, two factor authentication is required, at a minimum, unless the DAA has approved an exception based on the unavailability of a WMAN product that meets this requirement. Determine if two factor authentication is used (e.g. CAC) or if the DAA has granted an exception.

Since NTP is used to ensure accurate log file time stamp information, NTP could pose a security risk if a malicious user were able to falsify NTP information. To launch an attack on the NTP infrastructure, a hacker could inject time that would be accepted by NTP clients by spoofing the IP address of a valid NTP server. To mitigate this risk, the time messages must be authenticated by the client before accepting them as a time source. Two NTP-enabled devices can communicate in either client-server mode or peer-to-peer mode (aka "symmetric mode"). The peering mode is configured manually on the device and indicated in the outgoing NTP packets. The fundamental difference is the synchronization behavior: an NTP server can synchronize to a peer with better stratum, whereas it will never synchronize to its client regardless of the client's stratum. From a protocol perspective, NTP clients are no different from the NTP servers. The NTP client can synchronize to multiple NTP servers, select the best server and synchronize with it, or synchronize to the averaged value returned by the servers. A hierarchical model can be used to improve scalability. With this implementation, an NTP client can also become an NTP server providing time to downstream clients at a higher stratum level and of decreasing accuracy than that of its upstream server. To increase availability, NTP peering can be used between NTP servers. In the event the device loses connectivity to its upstream NTP server, it will be able to choose time from one of its peers. The NTP authentication model is opposite of the typical client-server authentication model. NTP authentication enables an NTP client or peer to authenticate time received from their servers and peers. It is not used to authenticate NTP clients because NTP servers do not care about the authenticity of their clients, as they never accept any time from them.
Checks: C-12793r9_chk

Review the network element configuration and verify that it is authenticating NTP messages received from the NTP server or peer using a FIPS-approved message authentication code algorithm. FIPS-approved algorithms for authentication are the cipher-based message authentication code (CMAC) and the keyed-hash message authentication code (HMAC). AES and 3DES are NIST-approved CMAC algorithms. The following are NIST-approved HMAC algorithms: SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256. Downgrade: If the network device is not capable of authenticating the NTP server or peer using a FIPS-approved message authentication code algorithm, then MD5 can be utilized for NTP message authentication and the finding can be downgraded to a CAT III. If the network element is not configured to authenticate received NTP messages using a FIPS-approved message authentication code algorithm, this is a finding. A downgrade can be determined based on the criteria above.

If an adversary is able to compromise an access point or controller that is directly connected to an enclave network, then the adversary can easily surveil and attack other devices from that beachhead. A defense-in-depth approach requires an additional layer of protection exist between the WLAN and the enclave network. This is particularly important for wireless networks, which may be vulnerable to attack from outside physical perimeter of the facility or base given the inherent nature of radio communications to penetrate walls, fences, and other physical boundaries.System Administrator

Detailed policy requirements: Wireless access points and bridges must not be directly connected to the enclave network. A network device must separate wireless access from other elements of the enclave network. Sites must also comply with the Network Infrastructure STIG configuration requirements for DMZ, VLAN, and VPN configurations, as applicable. Examples of acceptable architectures include placing access points or controllers in a screened subnet (e.g. DMZ separating intranet and wireless network) or dedicated virtual LAN (VLAN) with ACLs. Check Procedures: Review network architecture with the network administrator. 1. Verify compliance by inspecting the site network topology diagrams. 2. Since many network diagrams are not kept up-to-date, walk through the connections with the network administrator using network management tools or diagnostic commands to verify the diagrams are current.

Check Procedures: For non-tactical WMAN systems, verify the system uses either User ID and password or shared secret authentication between the User or WMAN subscriber device (respectively) to the WMAN network. If User ID and password is used, verify the password meets the length requirements of CTO 07-15Rev1. Mark as a finding if the password length requirements are not met.

Detailed Policy Requirements: The IAO has not ensured that site WMAN systems implement strong authentication from the User or WMAN subscriber device to WMAN network. -For tactical or commercial WMAN systems operated in a non-tactical environment: User ID and password or shared secret authentication shall be implemented between the User or WMAN subscriber device to the WMAN network. When user ID and password are used, the complexity requirements of the password must be compliant with JTF-GNO CTO 07-15Rev1: --Password complexity is a case sensitive mixture of upper case letters, lower case letters, special characters, and numbers, including at least one of each. Check Procedures: - For non-tactical WMAN systems, verify the system uses either User ID and password or shared secret authentication between the User or WMAN subscriber device (respectively) to the WMAN network. If User ID and password is used, verify the password meets the complexity requirements of CTO 07-15Rev1. Have the system administrator show the password complexity settings in the management console of the WMAN access point. Mark as a finding if the requirements are not met.

Without synchronized time, accurately correlating information between devices becomes difficult, if not impossible. If logs cannot be successfully compared between each of the routers, switches, and firewalls, it will be very difficult to determine the exact events that resulted in a network breach incident. NTP provides an efficient and scalable method for network devices to synchronize to an accurate time source.System AdministratorInformation Assurance Officer
Checks: C-3581r5_chk

Review the configuration and verify two NTP servers have been defined. If the device is not configured to use two separate NTP servers, this is a finding.

Fix: F-3044r2_fix

Configure the device to use two separate NTP servers.

Review the device configuration to determine if the call home service or feature is disabled on the device. If the call home service is enabled on the device, this is a finding. Note: This feature can be enabled if the communication is only to a server residing in the local area network or enclave.

Fix: F-31103r2_fix

Configure the network device to disable the call home service or feature. Note: This feature can be enabled if the communication is only to a server residing in the local area network or enclave.
