At the command line, execute the following command:
# for SETTING in $(/sbin/sysctl -aN --pattern "net.ipv4.conf.(all|default|eth.*).send_redirects"); do sed -i -e "/^${SETTING}/d" /etc/sysctl.conf;echo $SETTING=0>>/etc/sysctl.conf; done
At the command line, execute the following command:
# /sbin/sysctl -a --pattern "net.ipv4.conf.(all|default|eth.*).send_redirects"
Expected result:
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.default.send_redirects = 0
net.ipv4.conf.eth0.send_redirects = 0
If the output does not match the expected result, this is a finding.
Note: The number of "ethx" lines returned is dependent on the number of interfaces. Every "ethx" entry must be set to "0".
