As mentioned in the post "Best practice network design" (which you can read here), one of the tools a network administrator is required to have to securely manage servers is a jump server. A
jump server is installed in a partitioned section of the network and
access is provided to this server using a policy based network path. The
jump server is then the only network device that has network level
access to the administrative consoles of servers. This prevents these
consoles from being accessible to anyone on the internal network were
only application level access is provided. Administrators gain access to
the jump server using signed certificates which provides a high level
of trust and authentication. The normal server challenge methods are
then also applied on the server consoles.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use. Access this neat software over on github: easywall
