Firewall And Firewall Migration – Necessary Security Aspects

Network security is crucial in this era when the cyber-crimes are increasing rapidly with the passage of every single day. They are becoming a major threat to the organizations that are working online and relying on the internet. Such businesses are a real feast for them; they are attacked and penalized very often in case if they don’t have a proper security structure that could save them from such severe vulnerable attacks.


If you want a complete and excellent protection system for your network, then the firewall is something awesome for that reason. It helps your network remain safe from the vulnerable attacks via the internet. It does take care of all the activities happening within your network. The inbound and outbound activities coming from your network are monitored throughout for any suspicious activity.

In case if there is something suspicious happening around, the firewall detects it and blocks it right away. This is the best part one could say because your network firewall can detect the vulnerable stuff and block it to keep you safe from major after effects. So, one must have such a mechanism to ensure safety from the attacks of modern-day vulnerabilities.

Firewall Migration

The vulnerable attacks don’t remain the same forever; the intensity and approach of such threats do change with the passage of time. In that case, the firewall migration becomes a really necessary process. This is how you improve the performance of your particular firewall by updating it. Every migration takes place to enhance the tools and software systems of a particular firewall. That’s why you can’t neglect that part either.

If you are not going to take the firewall migration seriously, then it can certainly make you pay in the long run. As soon and as much as the cyber threats get intensified, as a company, you are supposed to take necessary steps as well to make your network capable of blocking those vulnerable attacks in a better way. Otherwise, you would need to face the worst consequences of negligence.

Safe Firewall Migration

It’s not the matter of migrating your firewall, in reality, it is about safely migrating it without leaving any weaknesses around. If you are attempting firewall migration but you are not doing it appropriately then there is no benefit of even attempting.

Let’s discuss in detail about how you can safely migrate your firewall?

Hiring Professional Staff

You need to ensure that the staff that’s taking part in the migration process is well-trained and knows the right procedure for it. Even if you have hired the services of a 3rd party service provider, in that case as well; the staff and resources are supposed to be highly skilled.

Audit Configuration

There is no need to build your configuration from scratch. The Audit configuration is there to help you with that. Analyze the unused addresses and services; analyze the current role and security base as well to determine the current policies that are in use to remove the previous and unused ones.

Composing Acceptance Test

Performing an acceptance test is also really necessary. You can do it to know that post firewall setup is working fine and perfectly. This certainly is the most necessary step whatsoever, to ensure that migration process has happened correctly.

Defining Rollback Procedure

What if you are tired of performing the migration process and you have to stop now to take rest? What would you do ensure that firewall migration couldn’t get harmed, even your network remains safe from the vulnerable attacks during that phase?

Defining a rollback procedure could help you significantly in this particular regard. As if you stop your migration process you can roll over the previous system to keep network safe from vulnerable attacks.

Final Lines

A firewall is the necessity of every network in this era because the cyber-attacks had increased a lot over last decade. If an organization doesn’t take care of its network security and neglects the importance of proper firewall, then it would have to bear with some worse consequences. Apart from the firewall, its migration is also necessary to make your security mechanism even stronger to deal with the even intense cyber-attacks.
