|
High |
The SEL-2740S must be adopted by OTSDN Controllers for secure communication identifiers and initial trust for configuration of remote maintenance and diagnostic communications. |
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to eavesdropping, potentially putting sensitive... |

Medium |
The SEL-2740S must employ automated mechanisms to assist in the tracking of security incidents. |
Despite the investment in perimeter defense technologies, enclaves are still faced with detecting, analyzing, and remediating network breaches and exploits that have made it past the network device. An automated incident response infrastructure allows network operations to immediately react to incidents by identifying, analyzing, and mitigating any network device compromise.... |

V-94589
|
Medium |
The SEL-2740S must authenticate Network Time Protocol sources using authentication that is cryptographically based. |
If Network Time Protocol is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will make log timestamps inaccurate and affect scheduled actions. NTP authentication is used to prevent this tampering by authenticating... |

Medium |
The SEL-2740S must be configured to send log data to a syslog server for the purpose of forwarding alerts to the administrators and the ISSO. |
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply create a new account. Notification of account creation is one method for mitigating this risk. A comprehensive account... |

Medium |
The SEL-2740S must be configured to establish trust relationships with parent OTSDN Controller(s). |
Machine to machine initial trust must be established between the OTSDN controller and the SEL-2740S for authenticating all communications and configuration thereafter. Certificates must be created and safely stored. Backup OTSDN controller trust should also be established and locked down. Any time that these need to be modified the SEL-2740S... |
|
V-92307
|
Medium |
The SEL-2740S must be adopted by OTSDN Controller(s) and obtain its public key certificates from an appropriate certificate policy through an approved service provider. |
For user certificates, each organization obtains certificates from an approved, shared service provider, as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified with the Federal Bridge Certification Authority at medium assurance or higher, this Certification Authority will suffice. |
|
V-92305
|
Medium |
The SEL-2740S must be configured to permit the maintenance and diagnostics communications to specified OTSDN Controller(s). |
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity.
This requirement addresses the configuration of network devices to mitigate the impact of DoS attacks that have occurred or are ongoing... |
|
V-92301
|
Medium |
The SEL-2740S must be configured to maintain internal system clocks with a backup authoritative time server. |
The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other functions.
Multiple time sources provide redundancy by including a secondary source. Time synchronization is usually a hierarchy; clients synchronize time... |
|
V-92299
|
Medium |
The SEL-2740S must be configured to synchronize internal system clocks with an authoritative time source. |
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events.
Synchronizing internal information system clocks provides uniformity of time stamps for information... |
|
V-92297
|
Medium |
The SEL-2740S must be configured to compare internal information system clocks at least every 24 hours with an authoritative time server. |
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside of the configured acceptable allowance (drift) may be inaccurate. Additionally,... |
|
V-92295
|
Medium |
The SEL-2740S must be configured to send log data to a Syslog server or collected by another parent OTSDN Controller. |
Protection of log data includes assuring log data is not accidentally lost or deleted. Regularly backing up audit records to a different system or onto separate media than the system being audited helps to assure, in the event of a catastrophic system failure, the audit records will be retained. |
|
V-92293
|
Medium |
The SEL-2740S must alert the ISSO and SA (at a minimum) in the event of an audit processing failure. |
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected.
Audit processing... |

V-92291
|
Medium |
The SEL-2740S must be configured to create log records for DoD-defined events. |
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
Audit records can be generated from various components within the network device (e.g., process, module). Certain specific device functionalities may be audited... |
