F5 BIG-IP TMOS ALG Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The F5 BIG-IP appliance providing content filtering must generate a log record when unauthorized network services are detected.

    Unauthorized or unapproved network services lack organizational verification or validation, and therefore may be unreliable or serve as malicious rogues for valid services. Examples of network ser...

  • The F5 BIG-IP appliance providing user access control intermediary services must limit the number of concurrent sessions to one or an organization-defined number for each access profile.

    The "Max In Progress Sessions Per Client IP" setting in an APM Access Profile is a security configuration that limits the number of simultaneous sessions that can be initiated from a single IP addr...
    Rule Medium Severity
  • The F5 BIG-IP appliance providing intermediary services for remote access communications traffic must ensure inbound and outbound traffic is monitored for compliance with remote access security policies.

    Automated monitoring of remote access traffic allows organizations to detect cyberattacks and also ensure ongoing compliance with remote access policies by inspecting connection activities of remot...
    Rule Medium Severity
  • The F5 BIG-IP appliance providing intermediary services for remote access must use FIPS-validated cryptographic algorithms, including TLS 1.2 at a minimum.

    Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DOD nonpublic information s...
    Rule High Severity
  • To protect against data mining, the F5 BIG-IP appliance providing content filtering must prevent code injection attacks from being launched against data storage objects, including, at a minimum, databases, database records, queries, and fields.

    Data mining is the analysis of large quantities of data to discover patterns and is used in intelligence gathering. Failure to prevent attacks launched against organizational information from unaut...
    Rule Medium Severity
  • The F5 BIG-IP appliance providing user access control intermediary services must implement attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

    Information flow control regulates where information is allowed to travel within a network. The flow of all network traffic must be monitored and controlled so it does not introduce any unacceptabl...
    Rule High Severity
  • The F5 BIG-IP appliance that provides intermediary services for HTTP must inspect inbound and outbound HTTP traffic for protocol compliance and protocol anomalies.

    Application protocol anomaly detection examines application layer protocols such as HTTP to identify attacks based on observed deviations in the normal RFC behavior of a protocol or service. This t...
    Rule Medium Severity
  • The F5 BIG-IP appliance providing user authentication intermediary services must require users to reauthenticate when the user's role or information authorizations is changed.

    Without reauthentication, users may access resources or perform tasks for which they do not have authorization. In addition to the reauthentication requirements associated with session locks, orga...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
