V-256090
|
High |
The Riverbed NetProfiler must be configured to implement cryptographic mechanisms using a FIPS 140-2/140-3 validated algorithm to protect the confidentiality and integrity of all cryptographic functions. |
If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to eavesdropping, potentially putting sensitive data (including administrator passwords) at risk of compromise and allowing hijacking of maintenance sessions.
Network devices using encryption are required to use FIPS-compliant mechanisms for authenticating to... |
|
V-256084
|
High |
The Riverbed NetProfiler must be configured to terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after 10 minutes of inactivity except to fulfill documented and validated mission requirements. |
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 that has been left unattended. In addition, quickly terminating an idle session will free up resources committed by the... |

V-256079
|
High |
The Riverbed NetProfiler must be configured to authenticate each administrator prior to authorizing privileges based on roles. |
The lack of role-based access control could result in the immediate compromise of and unauthorized access to sensitive information. Additionally, without mapping the PKI certificate to a unique user account, the ability to determine the identities of individuals or assert nonrepudiation is lost.
Individual accountability mandates that each administrator is... |
|
V-256072
|
High |
The Riverbed NetProfiler must be configured to automatically generate DOD-required audit records with sufficient information to support incident reporting to a central log server. |
Auditing can be disabled in the NetProfiler. The aggregation of log data kept on a syslog server can be used to detect attacks and trigger an alert to the appropriate security personnel. Upon gaining access to a network device, an attacker often attempts to create or change accounts to ensure... |
|
V-256097
|
Medium |
The network device must terminate shared/group account credentials when members leave the group. |
A shared/group account credential is a shared form of authentication that allows multiple individuals to access the network device using a single account. If shared/group account credentials are not terminated when individuals leave the group, the user that left the group can still gain access even though they are no... |
|
V-256094
|
Medium |
The Riverbed NetProfiler must be configured to 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-256092
|
Medium |
The Riverbed NetProfiler must be configured to use redundant Syslog servers that are configured on a different system than the NetProfiler appliance. |
Information stored in one location is vulnerable to accidental or incidental deletion or alteration.
Offloading is a common process in information systems with limited audit storage capacity. |
|
V-256091
|
Medium |
The Riverbed NetProfiler must be configured to protect against known types of denial-of-service (DOS) attacks by restricting web and SSH access to the appliance. |
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-256089
|
Medium |
The Riverbed NetProfiler must be configured to authenticate Network Time Protocol (NTP) sources using authentication that is cryptographically based. |
If NTP 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 the time... |
|
V-256088
|
Medium |
The Riverbed NetProfiler must be configured to authenticate SNMP messages using a FIPS-validated Keyed-Hash Message Authentication Code (HMAC). |
Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk.
A local connection is any connection with a device communicating without the use of a network. A... |
|
V-256087
|
Medium |
The Riverbed NetProfiler must be configured to record time stamps for audit records that meet a granularity of one second for a minimum degree of precision. |
Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records. Time stamps generated by the application include date and time. Granularity of time measurements refers to the degree of synchronization between information system clocks and reference clocks. |
|
V-256086
|
Medium |
The Riverbed NetProfiler must be configured to record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC). |
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis.
Time stamps generated by the application include date and time. Time is commonly expressed in UTC, a modern continuation of Greenwich Mean Time (GMT), or local time with an... |
|
V-256085
|
Medium |
The Riverbed NetProfiler must be configured to synchronize internal information system clocks using redundant authoritative time sources. |
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-256082
|
Medium |
The Riverbed NetProfiler must require that at least one special character be used. |
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks.
Password complexity is one factor of several that determine how long it... |

V-256075
|
Medium |
The Riverbed NetProfiler must be configured to retain the Standard Mandatory DOD Notice and Consent Banner on the screen until the administrator acknowledges the usage conditions and takes explicit actions to log on for further access. |
The administrator must acknowledge the banner prior to the device allowing the administrator access to the network device. This provides assurance that the administrator has seen the message and accepted the conditions for access. If the administrator does not acknowledge the consent banner, DOD will not be in compliance with... |
|
V-256074
|
Medium |
The Riverbed NetProfiler must be configured to display the Standard Mandatory DOD Notice and Consent Banner before granting access to the device. |
Display of the DOD-approved use notification before granting access to the network device ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.
System use notifications are required only for access via logon interfaces with human users. |
|
V-256073
|
Medium |
The Riverbed NetProfiler must enforce the limit of three consecutive invalid logon attempts, after which time it must block any login attempt for 30 minutes, at a minimum. |
By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. in NetProfiler, the default "Number of log-in attempts before account is locked" is 3, and the default "Number of minutes to keep account locked" is... |
