How can I discover hacker intrusion traces without an intrusion detection system?

The following describes how to detect hacker intrusion when there is no intrusion detection system. Hacker intrusion features generally come from the following four aspects. If a hacker intrude into the system, you can find the

Notice on purchasing Intrusion Detection System and Intrusion Protection System

Nowadays, enterprises have many choices to protect the network from external attacks. For example, firewall is a good choice. In most cases, it can distinguish abnormal data packets, therefore, we can take timely measures to prevent problems before they happen. However, for most enterprises, IDS is the best choice to completely isolate potential threats. Intrusion detection and defense are generally used to

Detailed description wireless intrusion detection system is required for wireless LAN

With the increase in hacker technology, wireless LAN (WLANs) is under more and more threats. Session hijacking and DoS attacks caused by misconfiguration of wireless base stations (WAPs) affect the security of Wireless LAN. Wireless networks are not only attacked based on the traditional wired network TCP/IP architecture, but may also be threatened by the security issues of the 802.11 standard issued by the Institute of Electrical and Electronics Engineers (IEEE. To better detect and defend agai

Wireless Intrusion Detection System

Now with the improvement of hacker technology, the wireless local area network (WLANS) is threatened more and more. The failure to configure a wireless base station (WAPS) causes session hijacking and denial of service attacks (Dos) to be like a plague that affects the security of wireless LANs in general. Wireless networks are vulnerable not only to the traditional wired network TCP/IP architecture but also to the security issues of the Institute of Electrical and Electronics Engineers (IEEE) r

Configure a host-based Intrusion Detection System (IDS) on CentOS)

Configure a host-based Intrusion Detection System (IDS) on CentOS) 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

The problems faced by IDs intrusion detection system

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

Implementation of IPV6 fragment recombination in intrusion detection system

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

The limitation of firewall and the characteristics of intrusion detection system

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,
