Fix Recommendation

Navigate to and open:

/etc/sysctl.d/zz-stig-hardening.conf

Add or update the following lines:

net.ipv4.conf.all.log_martians = 1
net.ipv4.conf.default.log_martians = 1

At the command line, run the following command to load the new configuration:

# /sbin/sysctl --load /etc/sysctl.d/zz-stig-hardening.conf

Note: If the file zz-stig-hardening.conf does not exist, it must be created.

Check Contents

At the command line, run the following command to verify martian packets are logged:

# /sbin/sysctl -a --pattern "net.ipv4.conf.(all|default).log_martians"

Expected result:

net.ipv4.conf.all.log_martians = 1
net.ipv4.conf.default.log_martians = 1

If the "log_martians" kernel parameters are not set to "1", this is a finding.
