intrusion detection system software

I. Problems to be faced Intrusion detection systems (intrusion detection system, IDS) are the hot security products in the past two years, which play a role in the network security system can detect

fragment package is reorganized by the destination node after the packet belonging to the same original IP packet arrives at the destination node. Unlike IPv4, the IPV6 fragment operation can only be performed at the source node, while the former is also available on intermediate nodes (such as intermediate routers) along the way. IP fragment packets can be forwarded independently through different paths, and the order of the destination nodes may not necessarily maintain the order of departure

From a network administrator's point of view, the world can be clearly divided into two camps. Part of the good guys, they belong to the Agency network, which can access resources in the network of the institution in a relatively unrestricted manner, and the other part is a malicious attacker who has to be carefully scrutinized to determine whether they are allowed to access network resources. Then these security tasks are done by firewalls, intrusion

Because UNIX systems often undertake key tasks, they are often the first choice for intruders to attack. Therefore, intrusion detection and system security protection are one of the most important tasks of administrators. So, without the help of other tools, how can we determine the current security of the system? How

CentOS installation and configuration host-based Intrusion Detection System (IDS) One of the first security measures that system administrators want to deploy on their production servers is to detect file tampering-not only file content, but also their attributes. AIDE (referred to as "Advanced

As an excellent open-source host intrusion detection system, Snort can be installed and run on both windows and Linux platforms. As a Linux operating system based on desktop applications, Ubuntu can also install Snort. During the Snort installation process, [install LAMP, Snort and some

The firewall has two main limitations:1, the firewall is Access control equipment (ACL), mainly based on the source IP address to real access control, to achieve the security of the network layer, but can not detect or intercept the injection in ordinary traffic malicious attack code, such as the Web service injection attacks.2. The firewall is unable to detect or intercept attacks that occur in the internal network.Firewall is the first line of defense to achieve network security,
