System Administrators are primarily responsible for keeping
systems/computers/network devices to work smoothly and securely in any
organization. Further they are also responsible for the continuous operations
of the networks and computers to the end users for their business needs. It is
very important to the System Administrator’s to keep the information as much
securing the system and network devices in the organization.
As
information infrastructure and Internet became more complex and larger, it also
became critical to maintain systems up and running all the time with respect to
security. Though the system administration tasks became easier in recent years,
system administrators need to be more updated on the systems and network
Security they are managing. In recent years, all systems are exposed to
Internet; there is increased challenge on System Administration/Network
Administration for maintaining and protecting from the attackers.
By
following simple practices/standards during their administrative functions,
they can maintain the security of IT devices. The practices for security also
help in reporting security incidents at an early stage and take corrective
measures so that they can safe guard the business. As part of Awareness, ISEA
Phase-II introduces best practices and guidelines for systems and network
devices.

If the
System Administrators are more cautious and follow good practices during
routine administrative tasks. It would be easy to maintain and secure IT systems
and networks in the organization. The system admin should have their own policy
as per the organization policy:
Ø
Because to maintain system intact as per the organization policy
Ø To give seamless
support to the end users
Ø Every organization
must have an overall policy that establishes the direction of the organization
and its security mission as well as roles and responsibilities.
Ø There can also be
system specific rules to address the policies for individual systems, network
and application security.
Ø These policies
should be included in the employee handbook and uploaded on a company intranet
site.
Ø
Before keeping the system and network devices in the work place
or in the existing network, it is very important to follow some of the best
system/network practices
Ø Harden the Operating
System before keeping into the network
Ø Harden the
Integrated OS and its application’s installed
Ø Have all the network
architecture in one place
Ø Harden the network
by using the vulnerability Assessment process for any open ports and any
vulnerable applications
Ø Harden the Servers
by running least services which is actually required
Ø Always have an
knowledge update on the security loopholes of the systems and networks
Ø Always provide the
physical security to the internetworking devices attached to the network
Ø Always Document the
systems/Networks configuration’s and whenever any changes happen
Ø Monitor Your Systems
Periodically by downloading the system/network logs
Ø System Administrator
and Network Admin need to educate users and help-desk personnel about basic
security issues and practices to follow.
