Vulnerability discussion

Network analysis tools allow for the capture of network traffic visible to the system.If the system is being used as a network analysis/troubleshooting system then these tools are allowed if documented.

Check content

Determine if any network analysis tools are installed. Procedure: # find / -name ethereal # find / -name wireshark # find / -name tshark # find / -name nc # find / -name tcpdump # find / -name snoop If any network analysis tools are found, this is a finding.

Fix text

Remove each network analysis tool binary from the system. Remove package items with a package manager, others remove the binary directly. Procedure: Find the binary file: # find / -name Find the package, if any, to which it belongs: # rpm -qf Remove the package if it does not also include other software: # rpm -e or # yum remove If the item to be removed is not in a package, or the entire package cannot be removed because of other software it provides, remove the item's binary file. # rm

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.
