fiber optic 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

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

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

Currently, application-level intrusion into applications and their background databases has become increasingly rampant, such as SQL injection, cross-site scripting attacks, and unauthorized user access. All these intrusions may bypass the front-end security system and initiate attacks against data sources. To deal with such threats, the new level of security stands out, which is application security. This

Article Title: about the use of Linux kernel security intrusion detection system. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This section briefly introduces the Linux kernel se

Build a small Intrusion Detection System (RedHat9) Snort + Apache + PHP4 + MySQL + Acid 1. the Redhat9.0 release of the system platform installs gcc and related library files. we recommend that you do not install Apache, PHP, and MySQL. we will compile and install them using the source code. Based on security considera

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,

Suricata is a network intrusion detection and protection engine developed by the Open Information Security Foundation and its supported vendors. The engine is multi-threaded and has built-in support for IPv6. You can load existing snort rules and signatures, Support for Barnyard and barnyard2 tools Suricata 1.0 improvements: 1. Added support for tag keywords;2. DCERPC supporting UDP;3. Duplicate signature

Project background:AIDE ("Advanced Intrusion Detection Environment" abbreviation) is an open source host-based intrusion detection system. Aide checks the integrity of the system binaries and basic configuration files by examining

applied data and is not included in the TCP/UDP/IP header. To achieve a higher level of security, the firewall must combine the packet filter and the application gateway. An application gateway, which is an application-specific server in which all application data must pass through the application gateway. Multiple application gateways can run on the same host, but each gateway is a separate server with its own process. However, the application gateway also has its drawbacks. First, each applic

, if a workstation's network interface is set to the multiplexing mode, it can receive all packets on the network. Snoop uses the features of sniffer to intrude into the system and places a sniffer on the intrusion basis. For example, in this test, an attacker from the Internet sends a Trojan horse to the workstation on the Intranet and places the sniffer. Then, the attacker of the Intranet routes the sniff
