What are the most obvious security threats with IPv6?
Here’s a list of the most common IPv6 threats that network vendors are hearing about from their enterprise customers:
- Rogue IPv6 traffic.
- IPv6 tunnels.
- Rogue IPv6 devices.
- Type 0 routing header.
- Built-in ICMP and multicast.
What is IPv6 and do I need it?
With IPv6 the purpose is to give all your devices a public IP address. In this case you do not long receive a single IPv4 address, but a whole /64 subnet with IPv6 address to give to your local devices. The amount of IP address you will receive with a /64 subnet will be more than you will ever need.
Why is IPv6 important for your network security?
IPv6 may introduce risks at the protocol level and many organizations do not include their network infrastructure in their patching plans, which might leave them open to nasty attacks. Now’s the time to check your processes in this area.
Why is there less scrutiny on IPv6 traffic?
Security tools, as well as security operations teams, also tend to give less scrutiny to IPv6 traffic. Hackers can take advantage of this in many ways, such as using an IPv6 proxy server to move laterally throughout an organization’s network or exfiltrate data with a lower chance of detection.
Do you need nats to use IPv6?
It may be comforting to have NATs in v6 environments but in reality they don’t provide any added security. The statefulness of the firewall provides security, not the translation of network addresses. IPv6 security cannot be a simple clone of what’s in place for IPv4 – that kind of thinking is dangerous.
Why do I have a blind spot in IPv6?
Our lack of awareness can lead to dangerous blind spots, such as hardening a server’s IPv4 attack surface while leaving IPv6 ports wide open. That lack of awareness extends beyond network engineers and sysadmins. Security tools, as well as security operations teams, also tend to give less scrutiny to IPv6 traffic.
