Vulnerability discussion

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 unacceptable risk to the network infrastructure or data. Information flow control policies and enforcement mechanisms are commonly employed by organizations to control the flow of information between designated sources and destinations (e.g., networks, individuals, devices) within information systems. Examples of information flow control restrictions include keeping export controlled information from being transmitted in the clear to the Internet or blocking information marked as classified but is being transported to an unapproved destination. ALGs enforce approved authorizations by employing security policy and/or rules that restrict information system services, provide packet filtering capability based on header or protocol information and/or message filtering capability based on data content (e.g., implementing key word searches or using document characteristics).

Check content

Verify the rules necessary to enforce approved authorizations for logical access to information and system resources by employing identity-based, role-based, and/or attribute-based security policies are configured, enabled and the respective "Applied to" category is configured if appropriate. Log into vSphere Web Client with credentials authorized for administration, navigate to Networking and Security >> Firewall >> Configuration tab >> General. Expand rule sections as necessary to view rules. If there are no rules configured to enforce authorizations, this is a finding.

Fix text

Log into vSphere Web Client with credentials authorized for administration. Remediate this finding by navigating to the Networking and Security >> Firewall tab on the left side menu >> Configuration tab >> General Configure the rules necessary to enforce approved authorizations for logical access to information and system resources by employing identity-based, role-based, and/or attribute-based security policies Ensure the rules have been enabled, and configure the respective "Applied to" category if appropriate.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
