1. How Do You Perform the Five Basic Steps for
Installing Firewalls?
Firewall Installation Dubai – A firewall is the first line of defense against online
attacks and is an important part of a network security system. With the
increasing use of the Internet in almost every business sector, misuse of data for
online fraud or unauthorized access to sensitive information has become the
most immediate threat to computer systems. A reliable firewall is essential for
organizations to secure and protect their systems.
5 steps required to install a firewall:
Protect your firewall: Protect your firewall in a few simple steps. This is the
first and most important step of installation. Update your firewall to the latest
firmware. All default usernames and passwords should be removed, renamed,
or disabled.
Always use only complex and strong passwords. If more than one administrator
manages the firewall, additional administrator accounts with limited privileges
should be created based on their responsibilities.
We do not recommend using shared user accounts. Configure Simple Network
Management Protocol (SNMP) to use secure community strings.
Plan firewall zones or IP addresses: To protect your critical assets, you
need to identify them. An organization's valuable assets include payment
information, employee or patient information, and business transactions. The
structure of the network should be planned in such a way that these valuable

2. assets can be grouped together based on similar levels of sensitivity and
functionality. After creating network zones, you can create firewall zones and
assign appropriate firewall interfaces to them.
Define access control lists: Now that the network zones have been created,
determine the traffic going into and 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.
Once your firewall is properly installed, you should monitor logs, update
firmware, perform vulnerability scans, and review firewall rules every six
months.
