| 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 or used for administrative access.
| Group accounts on any device are strictly prohibited. If these group accounts are not changed when someone leaves the group, that person could possibly gain control of the network device. Having... |
| 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-14891 | Medium | FIPS 140-2 validated encryption modules must be used to secure data in transit between free space optical (FSO) communication devices | Encryption is required to protect the confidentiality and integrity of the transmitted data. |
| V-3069 | Medium | The network element must only allow management connections for administrative access using FIPS 140-2 validated encryption algorithms or protocols. | Remote administration using non-FIPS 140-2 validated encryption is inherently dangerous because anyone with a sniffer and access to the right LAN segment can acquire the device's account and... |
| 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 | The network element must have all user accounts assigned to the lowest privilege level that allows each administrator to perform his or her duties.
| By not restricting administrators and operations personnel to their proper privilege levels, access to restricted functions may be allowed before they are trained or experienced enough to use... |
| 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-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-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... |
