To lend a hand the Division of Protection (DoD) and different machine directors in figuring out and minimising safety dangers associated with the transition to Web Protocol model 6 (IPv6), the Nationwide Safety Company (NSA) has launched IPv6 Safety Steerage.

The latest IP model, IPv6, provides advantages over the sooner IP model 4 applied sciences (IPv4). The IPv4 cope with area, particularly, is inadequate to care for the rising collection of networked units that require routable IP addresses, while IPv6 provides an enormous cope with area to meet each provide and long term wishes.

The NSA notes that the transition to IPv6 is expected to have essentially the most results on community infrastructure, affecting each and every networked {hardware} and device somehow, in addition to cybersecurity.

“Working twin stack will increase the operational burden and the assault floor. Gadget house owners and directors must enforce cybersecurity mechanisms on each IP protocols to give protection to the community”, reads the NSA’s IPv6 safety steerage.

Federal and DoD networks are anticipated to function twin stack, which means that they’ll concurrently run IPv4 and IPv6. This extends the assault floor and items further safety problems.

The use of stateless cope with auto-configuration (SLAAC), a number can robotically assign itself an IPv6 cope with. Static addresses could also be most well-liked in some instances, reminiscent of for vital servers, however permitting units to robotically self-assign or request an IPv6 cope with dynamically is more practical.

 “NSA recommends assigning addresses to hosts by way of a Dynamic Host Configuration Protocol model 6 (DHCPv6) servers to mitigate the SLAAC privateness factor”, states the company.

“Then again, this factor may also be mitigated via the usage of a randomly generated interface ID that adjustments through the years, making it tough to correlate process whilst nonetheless permitting community defenders considered necessary visibility”.

One protocol will also be transmitted inside of every other protocol the usage of the transitional approach referred to as tunneling.

“Except transition tunnels are required, NSA recommends warding off tunnels to cut back complexity and the assault floor. Configure perimeter safety units to come across and block tunneling protocols which are used as transition strategies”, the company printed IPv6 Safety Steerage.

The NSA advises enforcing IPv6 cybersecurity measures very similar to the ones installed position for IPv4, reminiscent of firewall laws, and blockading different transitional measures, together with tunneling and translation, for dual-stack networks.

Additional, directors must take a look at get right of entry to regulate lists (ACLs) or filtering laws to ensure that most effective visitors from licensed addresses is permitted as a result of more than one community addresses are continuously assigned to the similar interface in IPv6. They must additionally log all visitors and habits regimen log opinions.

The NSA additionally advises making sure that community directors download ok coaching and training on IPv6 networks as a way to higher offer protection to and strengthen IPv6 safety on a community.

Therefore, IPv6 safety threats do exist and shall be noticed, they are able to be decreased via a mix of strictly following configuration suggestions and machine house owners’ and directors’ coaching all the way through the transition.

“The Division of Protection will incrementally transition from IPv4 to IPv6 over the following couple of years and lots of DoD networks shall be dual-stacked,” mentioned Neal Ziring, NSA Cybersecurity Technical Director. 

“It’s vital that DoD machine admins use this information to spot and mitigate possible safety problems as they roll out IPv6 enhance of their networks.”
