comptia security practice

Network security experts use practice to tell you How situation awareness should be implemented and how network security situation should be handled. In a large-scale network environment, cybersecurity Situation Awareness obtains, understands, displays, and predicts the future development trend of all security elements

Instead, CSRF is borrowing the user's identity to send a request to Web server because the request is not intended by the user, so it is called "cross-site request forgery". The defense of CSSRF can be carried out from a few aspects; Referer, token or verification code to detect user submissions; Try not to expose the user's privacy information in the link of the page, for the user to modify the deletion and other operatio

The Java language provides flexible, seemingly simple threading capabilities that make it easy to use multithreading in your applications. However, concurrent programming in Java applications is more complex than it seems: in Java programs, there are subtle (and perhaps not subtle) ways to create data contention (race) and concurrency problems. In this Java theory and Practice, Brian explores a common thread hazard: Allow this reference to escape duri

For many enterprise network administrators, switches are naturally the most commonly used equipment. So how much do you know about vswitches? Next we will use an example to discuss the practice of vswitch port configuration and access security protection! Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the
