What are the Five Initial Steps for Firewall
Installation?
Firewall Installation Dubai – A Firewall is the first line of defence against online
attackers and is a crucial part of the network security system.
With the increasing use of the internet in almost all the business sectors, misuse
of data for online fraud or unauthorized access of vital information has become
the most imminent threat to computer systems.
A robust Firewall solution is a foremost necessity for organisations to keep their
systems secure and safe.
Five necessary steps for Firewall installation:
Secure the Firewall: Securing the firewall by following a few simple steps is the
first and foremost step of installation. Update firewall to the latest firmware.
All default usernames and passwords should be deleted, rename, or
disabled. Always use only complex and secure passwords.
If multiple administrators are managing the firewall, additional
administrator accounts with limited privileges must be created based on
responsibilities. Using shared user accounts is not recommended.
Configure a simple network management protocol (SNMP) to use a secured
community string.
Plan your firewall zones or IP addresses: Identifying the crucial assets is
necessary for protecting them. Valuable assets of an organization include
payment data, employee details, or patient details, or business transactions. The
network structure should be planned in such a way that these crucial assets can

be grouped together based on similar sensitivity levels and functions. After the
network zones are created the firewall zones can be created and assigned the
corresponding firewall interfaces.
Determine the Access Control lists: Now that the network zones are created,
determine which traffic needs to flow in or out of each zone. The firewall rules
called Access Control Lists are applied to each interface or sub interface on the
firewall and traffic will be permitted using these rules.
Configure other firewall services and logging: If the firewall is capable of acting
as a dynamic host configuration protocol server, network time protocol server,
intrusion prevention system then it must be first configured to use the services.
Test your firewall configuration: After configuring the firewall testing must be
conducted for its proper working. Firewall testing includes vulnerability scanning
and penetration testing. A proper backup of the firewall configuration must be
saved in a secure place for recovery in the advent of a hardware failure.
After the proper installation of the firewall, logs must be monitored, firmware
updated, vulnerability scans must be performed, and firewall rules must be
reviewed every six months.
