for effective network connection.
If you click on a network connection that has been found, this program will display a chart showing the signal strength of the problematic network connection. This chart is updated frequently. It displays both the reading of signals and the reading of background noise. If the network connection signal in a region is very weak, this function can help the Administrator determine whether there is interference from other radio sources, or this is only because the s
systems on critical hosts or devices in the network. This intrusion detection system detects the information package of the stream and the inbound stream-but only detects the traffic flowing through the devices that install these systems.

such as: access control, identity and authentication, encryption, firewall, virus detection and kill functions. But it can be compared with other security systems, such as firewall system, security Network management system and other enhanced collaboration to increase its own dynamic and flexible response and immune capabilities, to provide us with a more secure network environment.

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 intrusion traces in the following four aspects.
this article is a broad concept, including not only the attackers (such as malicious hackers) who have obtained control of the system beyond the legal scope, it also involves collecting vulnerability information, resulting in denial of access (Denial of Service) and other behaviors that cause harm to computer systems.
Intrusion detection, as the name suggests, is the discovery of
Wireless LAN to monitor and analyze user activities, identify the types of intrusion events, detect illegal network behavior, and trigger alarms for abnormal network traffic.
The wireless intrusion detection system is similar to the traditional intrusion detection system. H
detection system can only detect and respond to the damage system. Nowadays, intrusion detection system has been used in WLAN to monitor and analyze user's activity, to judge the type of intrusion event, to detect illegal network behavior and to alarm the abnormal network traffic.
The wireless

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 resources. Intrusion
. Examining the load capacity of the test system is to observe the influence of the different size network traffic, the different intensity CPU memory and other system resources on the key index of IDs (such as detection rate, false alarm rate).
Journal, good reporting, report, and responsiveness. Log capability is the ability to detect the ability of the system to save logs, and to select the contents of the log according to specific requirements. A
Security KIDS.The file integrity check tool checks the digital summary and other attributes of the file to determine whether the file is modified and detect possible intrusion. The products in this field are semi-open source Tripwire.IDS product formThe vast majority of intrusion detection products are sold in the form of pure
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 active defense technology that installs them
With the increasing risk coefficient of network security, firewalls, once the most important security defense means, cannot meet people's requirements for network security. As a supplement to firewalls and their benefits, IDS (Intrusion Detection System) can help network systems quickly detect attacks, it extends the security management capabilities of System Administrators (including security audit, monito
With the increasing of the risk coefficient of network security, the firewall, which used to be the main security precaution, can not meet the need of the network security. As a useful complement to the firewall, IDS (Intrusion detection System) can help the network system to quickly detect the occurrence of the attack, it extends the system administrator's security management capabilities (including securi
to provide unlimited access to the network and obtain key data through spoofing. Without knowing it, the wireless LAN User thought that he was connected to the wireless LAN through a good signal, but he was not aware that he had been listened to by hackers. With the low cost and ease of configuration, wireless LAN is becoming increasingly popular. Many users can also set up wireless base stations (WAPS) in their traditional LAN ), the backdoor programs installed by some users on the network als

(2) related firewalls: devices with network boundaries can be attacked by themselves, and some attacks are poorly protected. Not all threats come from outside the firewall. (3) Easy intrusion:
