iptables to secure my server. The default policies for all chains in the
filter table have been set to DROP
# iptables -t filter -L | grep -i \ (policy Chain INPUT (policy DROP) Chain FORWARD (policy DROP) Chain OUTPUT (policy DROP)
I wonder if it is useful to also set the policies to DROP for
security tables (not
nat table because it does not work)
in order to more secure the server ?
And of course duplicate the access rules for each tables setted to DROP
