Vulnerability discussion

In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable or restrict unused or unnecessary physical and logical ports/protocols on information systems.Applications are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Additionally, it is sometimes convenient to provide multiple services from a single component (e.g., email and web services; however, doing so increases risk over limiting the services provided by any one component.To support the requirements and principles of least functionality, the application must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved to conduct official business or to address authorized quality of life issues.

Check content

Review the application documentation and configuration. Interview the application administrator. Identify the network ports and protocols that are utilized by the application. Using a combination of relevant OS commands and application configuration utilities identify the TCP/IP port numbers the application is configured to utilize and is utilizing. Review the PPSM web page at: http://www.disa.mil/Network-Services/Enterprise-Connections/PPSM Review the PPSM Category Assurance List (CAL) directly at the following link: https://disa.deps.mil/ext/cop/iase/ppsm/Pages/cal.aspx Verify the ports used by the application are approved by the PPSM CAL. If the ports are not approved by the PPSM CAL, this is a finding.

Fix text

Configure the application to utilize application ports approved by the PPSM CAL.

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.
