Cirruswhat's Device ID in asm?
我想知道设备ID是什么以及它是由什么组成的？比如时间，源ip，源端口……实体是什么？
Device ID is an ASM / AdvWAF feature. The BIG-IP uses JavaScript to create a device ID from client. The JavaScript tries to obtain various signals from the client to retrieve attributes like the browser type and version, installed updates, installed fonts, and others. The BIG-IP stores the device ID in the TSPD101 cookie.
This information can be used for example with brute force attack prevention or web scraping protection.

As Rob says actual F5 contact is the best source.
But for your worry about forging things. Mostly everything can be forged. It is about being sure enough. There is no 100% in this.
I marked this as the Accepted Solution for you. 🙂
