fiber optic intrusion detection system

connected to the following Optical Fiber respectively: two input ports of the N-Shard, from 2: N-Shard to The ONU side using conventional connections, ONU using conventional ONU. When the system works normally, the switching control module can monitor the operating status and related alarm information of the olt pon module online, when the Protection Switching Control Module receives the line fault, signal

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

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

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

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

Article Title: perfect solution for using the intrusion detection system in linux. 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. 　　 Introduction to

This paper aims at the vulnerabilities of intrusion detection system to understand the hacker's intrusion methods. Once the network intrusion detection system is installed, the network

For the vulnerabilities in the intrusion detection system, let's take a look at hacker intrusion techniques. Once the network intrusion detection system is installed, the network

Zero-day attacks and distributed denial of service (DdoS) attacks brought by increasingly large botnets, many small and medium-sized enterprises that use traditional security equipment are exhausted, and the active defense technology can effectively solve the security problems brought about by these aspects. Intrusion detection and defense system (IDS/IPS) is an

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 wan

I. Intrusion Detection System Analysis 1.1 What is an intrusion detection system Intrusion refers to any attempt to endanger the integrity, confidentiality, or availability of computer

This article describes the hacker intrusion methods for the vulnerabilities in the intrusion detection system. Once the network intrusion detection system is installed, the network

In the construction of the actual intrusion detection and defense system, some enterprises mainly use the network to discover and block network threats. Some mainly use host defense to prevent host intrusion. If we build on one of them, there will be deviations. We recommend that you integrate multiple aspects of infor

Snort is a multi-platform, real-time traffic analysis intrusion detection system. Snort is a packet sniffer Based on libpcap and can be used as a lightweight network intrusion detection system. Snort has three working modes:1. sni

Snort is an IDs (intrusion detection System) software developed by the U.S. Sourcefire Company under the GPL v2 Snort has three modes of operation: sniffer, packet recorder, network intrusion detection system mode. The sniffer mo

Introduction to snort Snort is a packet sniffing Based on libpcap and can be used as a lightweight network intrusion detection system (NIDS ). The so-called lightweight means that the normal operations of the network are affected as low as possible during detection. An excellent lightweight NIDS should have cross-

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

Since computers are connected through networks, network security has become a major problem. With the development of the INTERNET, security system requirements are also increasing. One of its requirements is intrusion detection systems.This article aims to introduce several common Intrusion
