| 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 | Network devices must authenticate all NTP messages received from NTP servers and peers. | 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... |
| V-3043 | Medium | The network device must use different SNMP community names or groups for various levels of read and write access. | 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... |
| V-14717 | Medium | The network device 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-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 personnel are trained or experienced enough to use those... |
| V-3160 | Medium | Network devices must be running a current and supported operating system with all IAVMs addressed. | Network devices not running the latest tested and approved versions of software are vulnerable to network attacks. Running the most current, approved version of system and device software helps... |
| V-15432 | Medium | Network devices must use two or more authentication servers for the purpose of granting administrative access. | The use of Authentication, Authorization, and Accounting (AAA) affords the best methods for controlling user access, authorization levels, and activity logging. By enabling AAA on the routers in... |
| V-3013 | Medium | Network devices must display the DoD-approved logon banner warning. | 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... |
| V-3058 | Medium | Unauthorized accounts must not be configured for access to the network device. | A malicious user attempting to gain access to the network device may compromise an account that may be unauthorized for use. The unauthorized account may be a temporary or inactive account that... |
| 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-3969 | Medium | Network devices must only allow SNMP read-only access. | Enabling write access to the device via SNMP provides a mechanism that can be exploited by an attacker to set configuration variables that can disrupt network operations. |
| 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-5611 | Medium | The network devices 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-3967 | Medium | The network devices must time out access to the console port at 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-3966 | Medium | In the event the authentication server is unavailable, the network device must have a single local account of last resort defined. | Authentication for administrative access to the device is required at all times. A single account of last resort can be created on the device's local database for use in an emergency such as when... |
| V-17821 | Medium | The network devices OOBM interface must be configured with an OOBM network address. | The OOBM access switch will connect to the management interface of the managed network device. The management interface of the managed network device will be directly connected to the OOBM... |
| V-17822 | Medium | The network devices 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 device. The management interface can be a true OOBM interface or a standard interface functioning as the... |
| 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 device must be configured for a maximum number of unsuccessful SSH logon 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 devices 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-3014 | Medium | The network devices 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-23747 | Low | Network devices must use at least two 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-3070 | Low | Network devices 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-7011 | Low | The 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. ... |
