# find / -name tshark
# find / -name nc
# find / -name tcpdump
# find / -name snoop

If any network analysis tools are found, this is a finding

Implementation Procedure

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 <Item to be removed>

Find the package, if any, to which it belongs:
# rpm -qf <binary file>

Remove the package if it does not also include other software:
# rpm -e <package name>
or 
# yum remove <package name>

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 <binary file>
