All client and server interaction protocols will be placed in this log, and Vugen will then analyze the protocol interaction and eventually generate the script.
The recorded Vugen script is generated from this log. If you want to return to the original state after an error or error modification at the end of the recording, you can use the Tools>regenerate script feature to regenerate the scripts back to the original state.

Replay attacks are sometimes called demonstration attacks. An attacker can reproduce the data sent by a valid user to the server to obtain access or other permissions assigned to the user.
Like password sniffing, preventing replay attacks also requires you to be aware of data exposure. To prevent repla

When talking about transactional services in the afternoon, in addition to digital signatures for certificates, we also talked about replay attacks.
Replay attacks can be identified by serial numbers.
The serial number is divided into: 1. The service caller issues the serial number. 2. Issue a service provider.
Serial number generation methods are divided into two types: 1. No duplicates, random issuance. 2

If the client is making a request to the server-side interface, if the request information is encrypted, it is intercepted by a third party to the request packet, although the third party cannot decrypt the obtained data, but can use the request package for repeated request operation. If the service side does not carry out anti-replay attacks, the parameter server pressure increases, the consequences of data disturbance. You can solve this problem by
