Active threat defense now enabled by default in AWS Network Firewall

AWS Network Firewall

Starting today, AWS Network Firewall enables active threat defense by default in alert mode when you create new firewall policies in the AWS Management Console. Active threat defense provides automated, intelligence-driven protection against dynamic, ongoing threat activities observed across AWS infrastructure.

With this default setting you get visibility into threat activity and indicator groups, types, and threat names you are protected against. You can switch to block mode to automatically prevent suspicious traffic, such as command-and-control (C2) communication, embedded URLs, and malicious domains, or disable the feature entirely. AWS verifies threat indicators to ensure high accuracy and minimize false positives.

Active threat defense is available in all regions where AWS Network Firewall is available, including AWS GovCloud (US) and China Regions.

What to do

• Review your firewall policies to ensure they are configured with the default active threat defense setting.
• Monitor threat activity and adjust your settings as needed to balance protection and performance.
