🚨 Attention AWS Network Firewall users – check out this blog post! https://lnkd.in/eCnTrAec There is a potential for a bypass in the egress traffic control function of the AWS Network Firewall, which could allow entities within your Virtual Private Cloud (VPC) to spoof destination host names and circumvent the control. For HTTPS traffic, Network Firewall relies on SNI extension; for HTTP, it uses the host header. No out-of-band DNS lookups are performed. As a result, additional measures may be necessary to ensure the security of your network. To learn more about this issue and potential workarounds, check out the GitHub repo linked in the article. We recommend taking the necessary steps to safeguard your network. 🔐  #aws #securityalert #awssecurity
