In today’s world a network system is very necessary that secures, monitors, and controls the two way traffic which follows a set rules and paths that are pre devised. Basically it acts as a barrier between the right and secure internal traffic system and the external system. It also filters the bad traffic and the good trusted traffic.
The usual life span of packet filter is from 5 to 7 years and the upgrades or changes are enforced and started by the organizations growth or if the need is to change the security plan.
The importance of packet filter is huge as it acts as a filter between the good traffic and bad traffic. Its significance to the critical network security can be measured by enforcing any change in it, as even a slightest of changes can load the system with numerous risks and threats. Any immature change in packet filter can stem the continuity of the business activities.
Firewall migration can only be done under careful and experienced supervision. If a person or corporation wants to change the packet filter necessary cautions should be taken in order to keep the previous data safe. There are some certain cares and steps that to be taken before changing it to the better version or installing it.
Before up gradation:-
Make sure to create the back up of all the data present in your system before you start upgrading it. Because, the chances of losing the data cannot be written off. Latest facilities and technology don’t let your data and files vanish
During the process of up gradation or installation careful monitoring and close supervision is needed, which need to be performed by experienced and skilled personnel.
First action after transformation:-
Once the up gradation process has finished the first action is taken. This action must be taken by having a look on packet filter groups that were formed previously. To make sure that groups exist or not and either they contain configured hosts and all networks.
Default host names:-
Most probably they may exist but due to some technical limitations proper host names cannot be displayed. Thus they are visible carrying default system name which may appear like this: host <ip-address>. You can change the names to the ones you like or the ones that show some sense so that the files and groups can be recognized.
If you haven’t used firewall migration before and don’t have any experience you may skip this step. But, the best and ideal solution for personal and enterprise needs is to get the service of any experienced and renowned IT firm in this regard.
