Simple Ways To Protect Your Network
During the last decade or so, cyber security has been one of the hottest topics discussed in the field of I.T. as the field of I.T is developing day by day and everything is depending on computers and cyber technology for its survival, storage and development. There are some negative users of technology as well. Cyber theft has been one of the great dangers faced in the world of tech nowadays.
Why Use:-
To counter the negativities of cyber theft, the firewall is used to stop the viruses, hackers, and worms that try to affect your computer when you use the internet. It is specially designed to prevent unauthorised entrance to your computer or private network through the internet.
How to get improved performance:-
Never change the firewall and the configuration at once. Change one of these two initially so that you can get back if needed otherwise all data will be lost. Always review firewall migration after the old configuration. Check the current configuration carefully all the address objects, services, and networks should be removed. This can be done easily with the help of Tools like juniper network and smart centre.
Analysis of rule base:-
Always keep on checking for the policies that are being used and which are the old ones that need to be deleted. These policies are different at every company. Some corporations have these administrators that have been working for years. Rule base analysis is performed to check the hit counter. This option is enabled on rule basis.
Translation of configuration:-
The configuration of the current firewall should be written again by the use of syntax. Migration of the configuration should be tested. The basic setup is arranged here.
· Interface Settings (physical, logical and IPs)
· Routing (dynamic routing protocols or static routes)
· High Availability Setup (clustering)
· Management Settings (users, remote access, AAA, SNMP, and Syslog)
These elements will not change frequently.
Automated or manual translation:-
Now the question arises should the work be automated or manual? A firewall having 1500 rules manual translation will be very difficult so the preferred option will be automated script.
One of the best firewalls now days is the Palo-alto. Firewall migration has always been a tough job to complete which can be done with the help of professional service providers from Palo-alto network or any other network who use automated tools and best possible ways to complete the task.
