PP118: IPv6 Risks In Dual-Stack Environments (i.e. Most Environments)
Operating in a dual-stack environment without accounting for IPv6 in monitoring and security exposes networks to risks such as VPN breakouts and unmanaged IPv6 exploitation by attackers.
MAIN POINTS
- Most environments operate in a dual-stack configuration unless fully migrated to IPv6.
- Ignoring IPv6 in security and monitoring can lead to significant vulnerabilities.
- Attackers can exploit unmanaged IPv6 to bypass security measures.
- VPN breakouts are a specific risk in dual-stack environments.
TAKEAWAYS
- Ensure IPv6 is included in network monitoring and security strategies.
- Regularly update security tools to manage both IPv4 and IPv6 traffic.
- Educate IT teams about the risks associated with dual-stack environments.
- Consider full migration to IPv6 to simplify security management.
