Understanding IPv6 security

08/18/2011


Network security is increasingly becoming a critical concern for businesses and consumers alike, and companies working toward IPv6 migration need to consider how switching to the new protocol will impact their security protocols.

In a recent Light Reading report, Merike Kaeo, chief network security architect for Double Shot Security, said IPv6 was originally designed to be much more secure than IPv4. However, the security systems built into IPv6 were designed to handle the types of attacks that were pervasive in the 1990s. This inherent security is not entirely capable of dealing with the more sophisticated threats that are emerging now.

"For instance, the IPv6 protocol spec mandated that you had to implement IPsec to be compliant. But in reality, when people first started implementing IPv6, they weren't always using IPsec, and if they were using it, that doesn't mean they are implementing it properly," Kaeo told the news source.

Regardless of how IPv6 will impact security, companies need to consider migrating to the new protocol to remain relevant as the internet grows. The rising popularity of connected devices has led to the impending exhaustion of IPv4 addresses, making the new protocol necessary in most settings.
