Things to keep in mind to successfully manage firewall migration

The security of the information is the key concern of today’s business. To deal with the security issues, organizations are now focusing on ensuring strong security for the access to corporate data, installation of critical security updates, and the security of connectivity to the data center from external users as well as internal users. This security issue gets more complicated and sensitive when you migrate your security policy to another platform.

Everything in the technology of cloud computing and distributed data center is going through abrupt changes. Therefore, it is very common that you may need to migrate the security policy to new platforms. Thus, it comes to the question of controlling and managing firewall migration. It is also important to understand how to manage firewall migration when solutions from multiple vendors are available to you with both physical and virtual appliances and you want to use them.
