Label:The role of replay tracking You can use a trace as a test tool, and when you call some stored procedures in the correct order, you will be able to regenerate specific failures. Tracking templates There are four options for saving a trace (file-to-Save As) 1. The trace files option is used to save the data in a binary format file, which is the fastest, and the least disk-byte-consuming method. 2. The trace table option is used to save the data t

Replay attacks, similar to repeated submissions of WEB forms, interface visitors use the same message body to constantly access the interface provider's process, resulting in increased pressure on the interface provider or even server failure, data loss and so on. The general practice of preventing replay attacks is for the requester and provider to contract a unique TID, which therequester carries with thi

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

Time Stamp effect The client makes a request to the server-side interface and, if the request information is encrypted, is intercepted by a third party to the request packet, which can be used to repeat the request operation. If the service side does not perform anti-replay attacks, the server pressure increases, and the use of timestamps to solve the problem. The previous article described the JWT Security verification operation, which now
