+# F5 iRules for JA4+ Network Fingerprinting within Access flow
+
+F5 iRules for generating JA4+ fingerprints.  Currently, only JA4, JA4S, JA4T, JA4L, and JA4H fingerprint iRules are provided.  More JA4+ fingerprint iRules *MAY* be added in the future.
+The using those fingerprints within Access flow whether to restrict or query ja4db for matching items.
+
+> [!WARNING]
+>DISCLAIMER: These iRules are provided as-is with no guarantee of performance or functionality.  Use at your own risk.
+>These iRules have been tested on F5 BIGIPs running TMOS versions 16.1 and 17.1.
+ 
+
+## What is JA4+ Network Fingerprinting?
+
+From the [FoxIO JA4+ Repo](https://github.com/FoxIO-LLC/ja4):
+>JA4+ is a suite of network fingerprinting methods that are easy to use and easy to share. These methods are both human >and machine readable to facilitate more effective threat-hunting and analysis. The use-cases for these fingerprints >include scanning for threat actors, malware detection, session hijacking prevention, compliance automation, location >tracking, DDoS detection, grouping of threat actors, reverse shell detection, and many more.
+
+Please read this blog post for more details: [JA4+ Network Fingerprinting](https://medium.com/foxio/ja4-network-fingerprinting-9376fe9ca637)
+
+To understand how to read JA4+ fingerprints, see [Technical Details](https://github.com/FoxIO-LLC/ja4/blob/main/technical_details/README.md)
