In the UNIX system, privileges, such as being able to change the system's notion of the current date, and access control, such as being able to read or write a particle file, are based on user and group IDs. when our programs need additional privileges or need to gain access to resources that they currently aren't allowed to access, they need to change their user or group ID to an ID that has the appropriate privilege or access. similarly, when our pr

Editor's note: Maybe IDS can be broken through, but it won't be so easy.
Some of our customers talked about Mr. Fred Cohen's excellent article about IDS system vulnerabilities, "50 methods to circumvent IDs ". All 50 methods are listed below. The original version can be obtained from the http://all.net. Mr. Cohen claims that the
With the wide application of intrusion detection system, the requirement of testing and evaluating intrusion detection system is more and more urgent. Developers want to test and evaluate the deficiencies in the product, users want to test and evaluate to help themselves choose the right intrusion detection products. Based on the current research, this paper introduces the criteria, indexes, method steps, data sources, environment configuration, test evaluation status and some problems in the in
During attacks, hackers can disguise themselves and bypass IDS detection. This is mainly used for IDS pattern matching to avoid IDS monitoring. This article describes how to bypass IDS detection for HTTP requests.

example, your IDS can be reconfigured to prohibit malicious traffic from outside the firewall. You should understand that the intrusion monitoring system works independently of the firewall.IDS of the intrusion monitoring system is different from system scanner. The system scanner scans System Vulnerabilities Based on the attack feature database. It focuses more on the configured vulnerabilities than the traffic currently in and out of your host. On

Summary: This article describes two general IDS evasion technologies based on HTTP protocol. These technologies include the old-style HTTP evasion technology and the new-style HTTP evasion technology. Although different types of evasion techniques are available, they all reside in the HTTP request URI section, using standard HTTP/1.0 and HTTP/1.1 protocols. The evasion technique in the request URI address is usually related to the URL encoding. For Ap
IDS technology
IDS can be divided into Host-based IDS (HIDS) and Network-based IDS (NIDS) based on different data sources ).
Both HIDS and NIDS can detect intrusion behaviors that the other party cannot detect and complement each other. The perfect IDS product should combine
