A Firewall Still Essential Under IPv6

 

FirewallAccording to John Curran, who serves the American Registry for Internet Numbers as its CEO, Internet Protocol version 6 is designed to offer more safety and security features than the current paradigm of IPv4.  In part, this is because IPv6 was designed from the start with security needs in mind.  This does not mean, however, that IPv6 will present small and medium-sized businesses with no challenges to overcome. 

Curran recently remarked upon this very point, stating that "while IPv6, theoretically, will provide us a long-term, more secure environment, short term people have to realize IPv6 is subject to potentially having things discovered in it."  The same was true for IPv4, of course.  The current protocol has been in use for more than two full decades and has been adjusted throughout this time to address emerging threats and other security issues.  IPv6 will likely also experience growing pains. 

Curran specifically recommended that organizations be sure to use a firewall even after IPv6 becomes the standard:  "You have to make sure you take the effort to secure it [your system] by setting up an appropriate firewall configuration.  Otherwise, you may find that you're passing up all of the appropriate IPv4 traffic but the same traffic when it arrives on IPv6 is given a free pass into your network." 

One of the best ways to set up and maintain a firewall to protect your internet-connected systems is to use a managed programs model for IT support.  In a managed programs approach, dedicated staff visit your premises on a scheduled basis to perform necessary IT services.
