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 element and a PC or terminal server when the later has been left unattended. In addition quickly terminating an idle session will also free up resources committed by the managed network element as well as reduce the risk of a management session from being hijacked. Setting the timeout of the session to 10 minutes or less increases the level of protection afforded critical network components.Information Assurance OfficerECSC-1

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. Additional war dial attacks on the device could degrade the device and the production network. Secured modem devices must be able to authenticate users and must negotiate a key exchange before full encryption takes place. The modem will provide full encryption capability (Triple DES) or stronger. The technician who manages these devices will be authenticated using a key fob and granted access to the appropriate maintenance port, thus the technician will gain access to the managed device (router, switch, etc.). The token provides a method of strong (two-factor) user authentication. The token works in conjunction with a server to generate one-time user passwords that will change values at second intervals. The user must know a personal identification number (PIN) and possess the token to be allowed access to the device.Information Assurance OfficerECSC-1

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 infrastructure, a hacker could inject time that would be accepted by NTP clients by spoofing the IP address of a valid NTP server. To mitigate this risk, the time messages must be authenticated by the client before accepting them as a time source. Two NTP-enabled devices can communicate in either client-server mode or peer-to-peer mode (aka “symmetric mode”). The peering mode is configured manually on the device and indicated in the outgoing NTP packets. The fundamental difference is the synchronization behavior: an NTP server can synchronize to a peer with better stratum, whereas it will never synchronize to its client regardless of the client’s stratum. From a protocol perspective, NTP clients are no different from the NTP servers. The NTP client can synchronize to multiple NTP servers, select the best server and synchronize with it, or synchronize to the averaged value returned by the servers. A hierarchical model can be used to improve scalability. With this implementation, an NTP client can also become an NTP server providing time to downstream clients at a higher stratum level and of decreasing accuracy than that of its upstream server. To increase availability, NTP peering can be used between NTP servers. In the event the device looses connectivity to it upstream NTP server, it will be able to choose time from one of its peers. The NTP authentication model is opposite of the typical client-server authentication model. NTP authentication enables an NTP client or peer to authenticate time received from their servers and peers. It’s not used to authenticate NTP clients because NTP servers don’t care about the authenticity of their clients, as they never accept any time from them. Information Assurance OfficerECSC-1
Checks: C-12793r5_chk

Review the device configuration and verify it is authenticating the NTP messages received from the NTP server or peer. Authentication must be performed using either PKI (supported in NTP v4) or SHA-1 hashing algorithm. If SHA-1 is not supported by both the NTP client and server, then MD5 can be used.

Fix: F-14132r1_fix

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 signals to be received outside the physical areas for which they are intended. This may occur when the intended area is relatively small, such as a conference room, or when the access point is placed near or window or wall, thereby allowing signals to be received in neighboring areas. In such cases, an adversary may be able to compromise the site’s OPSEC posture by measuring the presence of the signal and the quantity of data transmitted to obtain information about when personnel are active and what they are doing. Furthermore, if the signal is not appropriately protected through defense-in-depth mechanisms, the adversary could possibly use the connection to access DoD networks and sensitive information.System AdministratorECTC-1
Checks: C-13418r1_chk

Review documentation and inspect AP locations. 1. Review documentation showing signal strength analysis from site survey activities, if available. 2. Use testing equipment or WLAN clients to determine if the signal strength is, in the reviewer’s judgment, excessively outside the required area (e.g., strong signal in the parking area, public areas, or uncontrolled spaces). 3. Lower end APs will not have this setting available—in this case, the site should locate the APs away from exterior walls to achieve compliance with this requirement. 4. Mark as a finding if any of the following is found. o Visual inspection of equipment shows obvious improper placement of APs where it will emanate into uncontrolled spaces (e.g., next to external walls, windows, or doors; uncontrolled areas; or public areas). o Building walk-through testing shows signals of sufficient quality and strength to allow wireless access to exist in areas not authorized for WLAN access.

Fix: F-3445r1_fix

Move APs to areas in which signals do not emanate in a manner making them usable outside the areas authorized for WLAN access. Alternatively, replace omni-directional antennae with directional antennae if this will solve the problem. If these solutions are not effective, then adjust the transmission power settings on the AP to reduce the usability of signals in unauthorized areas. If the WLAN equipment does not allow the transmission power to be adjusted, and the APs are placed in a location where the IAO determines there is significant risk that an adversary could be present in location where signals may be intercepted, then the site should procure WLAN equipment that permits power adjustment.
