typesFrom the examples discussed above, we can see multiple header values that can be used to create IDS features. Generally, the following elements are most likely to be used to generate header-related features:
IP addresses, especially reserved addresses, non-route addresses, and broadcast addresses.The port number that should not be used, especially the well-known protocol port number and Trojan port number.Exception information package.Special TC

This article briefly introduces several Linux IDS intrusion detection tools, such as psad, Apparmor, and SELinuxu. First, let's take a look at the principles and practices of the intrusion detection system.
If you only have one computer, it is entirely possible for you to spend a lot of time carefully reviewing system vulnerabilities and problems. Maybe you don't really want this, but it does. However, in the real world, we need some good tools to hel
We know that when a style table defines a style, you can define the ID or class, for example:
Id method: # test {color: #333333}, call the content on the page
Class Method:. Test {color: #333333}, call the content on the page
ID: a page can be used only once, and the class can be referenced multiple times.
Some netizens asked, the ID and class seem to be no different. I used multiple IDs on the page to display them normally in IE. What is the impa
When you get the field ID and the method ID , you need to do a search with the field, the name of the method, and the descriptor. The retrieval process is relatively time-consuming, so this section discusses using caching techniques to reduce the cost of this process. There are two main ways to cache field IDs and method IDs . The two differences are primarily in the time at which the cache occurs, when the
Php selects records with IDs in the array from the database and arranges them in the order of the array?

Questions raised:
Intrusion Detection (IDS) is a special security device that is used to discover hacker intrusion. Early in the time is very simple, is a log analyzer, like a needle in the log to extract the hacker's visit records; Later, the hacker learned to be good, before leaving their own "stain" record all erased; The record is gone, log analysis is hard to find hackers Of course, some novice hackers do not have this awareness and ability. Now
the firewall security policy setting function, it can immediately block attack actions, but this blocking action can only be applied to TCP sessions, it must be completely limited, it is necessary to re-adjust the firewall security policy setting function, and may also cause another anti-effect: the instant blocking action will allow attackers to discover the existence of IDS, attackers usually look for ways to circumvent or attack
