IntroducedWhen managing a networked server, server security is a very complex issue. Although you can configure firewalls, set up logging policies, buy security services, or lock apps, it's not enough if you want to make sure that every intrusion is blocked.A HIDS can collect your computer's file system and configuration, storing this information for reference and to determine the current state of operation of the system. If there is a change between the known safe state and the current state, i
ObjectiveWhen the server is attacked by hackers, in most cases, hackers may modify some important files, such as system files, and so on. In this respect, we use tripwire to establish data integrity monitoring system. Although it can not protect against hacker attacks and hackers on some important files, but the change is able to monitor whether the file has been modified and which files have been modified,
Now that tripwire itself is fully ready, the next thing we need to do is use it to perform an integrity check.
Iv. maintenance of policy files and profiles if you want to browse the tripwire policy and configuration, but they are stored in binary form or are currently missing, use the following command:

1. Introduction to rootkit
Rootkit is the most common backdoor tool in Linux. It mainly replaces system files for intrusion and concealment. This Trojan is more dangerous and concealed than a common backdoor, it is difficult to find such Trojans through common detection tools and detection methods. The rootkit has a strong attack capability and has a great harm to the system. It uses a set

I have encountered some problems in using axios recently. I feel it is necessary to share with you the basic knowledge about axios. For details, refer to this article: how to get started with axios, I won't talk much about it below. Let's take a look at the detailed introduction.

The STS and Virgo environments have been configured above, and the Virgo server can be successfully run. Next we will use STS to build several projects.
We simulate an example of registration. In our actual case, data is sometimes written to the database, written to a file, or written to the memory, which is convenient for different operations. This example may not completely explain the problem, but it is enough to explain how to build a project th

However, the MapReduce programming model has its own limitations. Its single input, two-stage data flows in strict, and the level is too low. For example, you would have to write custom code even for the most common operations. As a result, many programmers feel that the MapReduce framework is uncomfortable to
