Firewall Migration-A Critical Security Aspect
Firewall is the most critical security aspect for any network. Since, the vulnerabilities and cyber-crimes are at an extreme rise, that’s why the need of a proper and foolproof security system is more than just important. Especially talking about the large corporations around the world, they are much more under the threat of the cyber-attacks.
Why is Firewall Used?
A firewall is used to enhance the security level of any particular network. It helps in preventing the flow of the vulnerable and threat full traffic in a network. Only the trustable and non-vulnerable data could flow the firewall. Hence, it facilitates a network in remaining safe from getting penalized anyhow. This is the reason why firewall management is considered so important in the whole network security process.
Why is Firewall Migration Critical?
We all know that technology keeps on evolving with the passage of the time. Since technology evolve, thus the performances improve as well. Same is the case in firewall migration as well. When the technology is evolved in this niche, the migration becomes really necessary to make use of the latest and advanced technologies for the improved results.
The Firewall Migration Procedure:
Adopting the right firewall migration procedure is really important to ensure the outcome in the shape of the excellent results. The correct migration procedure is listed as follows.
Learning New Technology:
Learning the new technology is really crucial before implementing it. Every time when you are up to firewall migration, ensure that you have learnt the new technology well.
Reviewing Current Configurations:
It’s also a really critical aspect to review the current configurations of your firewall. Once you are done with it, you are good to move ahead further.
Translation Simulation:
The syntax of your current firewall is supposed to be written according to the latest one. The firewall configuration translation simulation is another necessary aspect.
Testing Phase:
Testing of the latest firewall configuration is the next important step. Make sure that the latest configuration you just did is working fine.
Declaration of Frozen zone:
Now it’s time to declare a frozen zone. You can estimate how long it is going to take to migrate and shift to your new firewall management system and declare that time as a frozen zone so the new policies could get migrated successfully.
Migration:
The last step is to make the migration take place successfully. After the successful migration you are all set with the updated and advanced firewall management system.
