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-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-3160 | Medium | The network element 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 | The network element 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 | The network element must display the DoD approved login banner warning in accordance with the CYBERCOM DTM-08-060 document. | 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... |
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-3969 | Medium | The network device 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-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-3966 | Medium | In the event the authentication server is down or unavailable, there must only be one local account created for emergency use. | Authentication for administrative access to the device is required at all times. A single account can be created on the device's local database for use in an emergency such as when the... |
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-25316 | Medium | The password configured on the WLAN Access Point for key generation and client access must be set to a 14 character or longer complex password as required by USCYBERCOM CTO 07-15Rev1. | If the organization does not use a strong passcode for client access, then it is significantly more likely that an adversary will be able to obtain it. Once this occurs, the adversary may be able... |
V-25315 | Medium | WLAN access point must be configured for Wi-Fi Alliance WPA2 security. | The Wi-Fi Alliance’s WPA2 certification provides assurance that the device has adequate security functionality and can implement the IEEE 802.11i standard for robust security networks. The... |
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... |
