| V-4582 | High | The network device must require authentication for console access. | Network devices with no password for administrative access via the console provide the opportunity for anyone with physical access to the device to make configuration changes enabling them to... |
| V-3056 | High | Group accounts must not be configured for use on the network device.
| Group accounts configured for use on a network device do not allow for accountability or repudiation of individuals using the shared account. If group accounts are not changed when someone leaves... |
| V-3143 | High | The network element must not have any default manufacturer passwords. | Network elements not protected with strong password schemes provide the opportunity for anyone to crack the password thus gaining access to the device and causing network outage or denial of... |
| V-3210 | High | The network element must not use the default or well-known SNMP community strings public and private. | Network elements may be distributed by the vendor pre-configured with an SNMP agent using the well known SNMP community strings public for read only and private for read and write authorization. ... |
| V-3175 | High | The network device must require authentication prior to establishing a management connection for administrative access. | Network devices with no password for administrative access via a management connection provide the opportunity for anyone with network access to the device to make configuration changes enabling... |
| V-3069 | Medium | Management connections to a network device must be established using secure protocols with FIPS 140-2 validated cryptographic modules. | Administration and management connections performed across a network are inherently dangerous because anyone with a packet sniffer and access to the right LAN segment can acquire the network... |
| V-14671 | Medium | The network element must authenticate all NTP messages received from NTP servers and peers. | Since NTP is used to ensure accurate log file timestamp information, NTP could pose a security risk if a malicious user were able to falsify NTP information. To launch an attack on the NTP... |
| V-14717 | Medium | The network element must not allow SSH Version 1 to be used for administrative access. | SSH Version 1 is a protocol that has never been defined in a standard. Since SSH-1 has inherent design flaws which make it vulnerable to attacks, e.g., man-in-the-middle attacks, it is now... |
| V-30257 | Medium | WLAN EAP-TLS implementation must use certificate-based PKI authentication to connect to DoD networks. | DoD certificate-based PKI authentication is strong, two-factor authentication that relies on carefully evaluated cryptographic modules. Implementations of EAP-TLS that are not integrated with... |
| V-3057 | Medium | Authorized accounts must be assigned the least privilege level necessary to perform assigned duties.
| By not restricting authorized accounts to their proper privilege level, access to restricted functions may be allowed before authorized personell are trained or experienced enough to use those... |
| V-3014 | Medium | The network element must timeout management connections for administrative access after 10 minutes or less of inactivity. | 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... |
| V-14886 | Medium | Wireless access points and bridges must be placed in dedicated subnets outside the enclave’s perimeter. | 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... |
| V-28784 | Medium | A service or feature that calls home to the vendor must be disabled.
| Call home services or features will routinely send data such as configuration and diagnostic information to the vendor for routine or emergency analysis and troubleshooting. The risk that... |
| V-3967 | Medium | The network element must time out access to the console port after 10 minutes or less of inactivity. | 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 on the console or console port... |
| V-17821 | Medium | The network element’s OOBM interface must be configured with an OOBM network address. | The OOBM access switch will connect to the management interface of the managed network elements. The management interface of the managed network element will be directly connected to the OOBM... |
| V-17822 | Medium | The network elements management interface must be configured with both an ingress and egress ACL. | The OOBM access switch will connect to the management interface of the managed network elements. The management interface can be a true OOBM interface or a standard interface functioning as the... |
| V-14888 | Medium | The WLAN inactive session timeout must be set for 30 minutes or less. | A WLAN session that never terminates due to inactivity may allow an opening for an adversary to highjack the session to obtain access to the network. |
| V-3692 | Medium | WLAN must use EAP-TLS. | EAP-TLS provides strong cryptographic mutual authentication and key distribution services not found in other EAP methods, and thus provides significantly more protection against attacks than other... |
| V-3515 | Medium | The WLAN must use AES-CCMP to protect data-in-transit. | AES-CCMP provides all required WLAN security services for data in transit. The other encryption protocol available for IEEE 802.11i compliant robust security networks and WPA2 certified solutions... |
| V-5613 | Medium | The network element must be configured for a maximum number of unsuccessful SSH login attempts set at 3 before resetting the interface. | An attacker may attempt to connect to the device using SSH by guessing the authentication method and authentication key or shared secret. Setting the authentication retry to 3 or less strengthens... |
| V-5612 | Medium | The network element must be configured to timeout after 60 seconds or less for incomplete or broken SSH sessions. | An attacker may attempt to connect to the device using SSH by guessing the authentication method, encryption algorithm, and keys. Limiting the amount of time allowed for authenticating and... |
| V-5611 | Medium | The network element must only allow management connections for administrative access from hosts residing in the management network. | Remote administration is inherently dangerous because anyone with a sniffer and access to the right LAN segment, could acquire the device account and password information. With this intercepted... |
| V-23747 | Low | The network element must use two or more NTP servers to synchronize time. | 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,... |
| V-14846 | Low | WLAN SSIDs must be changed from the manufacturer’s default to a pseudo random word that does not identify the unit, base, organization, etc. | An SSID identifying the unit, site or purpose of the WLAN or is set to the manufacturer default may cause an OPSEC vulnerability. |
| V-7011 | Low | The network element’s auxiliary port must be disabled unless it is connected to a secured modem providing encryption and authentication. | 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. ... |
| V-3070 | Low | The network element must log all attempts to establish a management connection for administrative access. | Audit logs are necessary to provide a trail of evidence in case the network is compromised. Without an audit trail that provides a when, where, who and how set of information, repeat offenders... |
| V-14889 | Low | WLAN signals must not be intercepted outside areas authorized for WLAN access. | Vulnerability Discussion: Most commercially-available WLAN equipment is pre-configured for signal power appropriate to most applications of the WLAN equipment. In some cases, this may permit the... |
