have also added the wireless scanning function in related driver software. For example, the Proxim dual-mode card can simultaneously scan all suitable channels in the 802.11a and 802.11b frequencies, and intuitively display the signal strength and bandwidth. The perfect Wi-Fi protocol analyzer is much more powerful than the NetStumbler or NIC driver, and its implementation methods are quite different.

see the SSID? This is because the AP has enabled the Broadcast SSID option when setting it to facilitate User connection. If a hacker wants to steal confidential data by placing an illegal Rogue AP in the network, I believe it will not be silly enough to open the broadcast and tell the Administrator that there is an AP in your network with "excellent signal quality", right? We can boldly assume that all the SSID we don't know may be illegal, and any hidden SSID we don't see will be illegal! May

drinks coffee and uses his laptop to log on to the Internet. The salesperson uses the company's credit card to pay for his network access, and then uses his username and password to connect to the company's network. He accesses the customer's files, and log on to his bank network to check the balance of his bank deposits, and then cancel and leave the coffee shop. A salesperson connects to a hacker's simulated hotspot "network", so that a malicious hacker can obtain a large amount of informatio

Another reason is that "you can program it to do anything you want to do", especially when an error occurs, trigger an alarm through e-mail. Tool Name:NetscoutCompany Name: netscout website www.netscout.com Recommendation reason: One reader recommends netscout because it has good fault detection and performance management function

the-B Option to specify the multi-point Transfer Group IP address to start multiple iPerf servers. Then open your iPerf client and connect to the previously started multicast group iPerf server. Use the test tool iPerf to monitor wireless network performance: Graphical Test Result As described in this article, the iPerf program can be run in the command line, or in a Java implementation front-end tool named JPerf. JPerf not only simplifies the construction of complex command line parameters, b

manufacturers also in the relevant driver software to increase the wireless scanning function. The dual-mode card provided by Proxim can simultaneously scan all appropriate channels within the 802.11a and 802.11b bands and visually display signal strength and bandwidth. The perfect Wi-Fi protocol analyzer is much more powerful than NetStumbler or Nic-driven software, and the implementation is very different. Some protocol parsers can decode advanced protocols, includes a complete TCP/IP stack

a significant role. For example, AirMagnet survey not only uses Iperf to measure uplink and downlink performance, but it can also be used to analyze 802.11n recommended settings and quick voice evaluations. Veriwave Wavedeploy is an agent-based site assessment tool that generates test streams that, when sent to real-world client devices, not only measure TCP throughput, but also measure the "quality of experience" of web, voice, and video.

WLAN upgrade is an opportunity to deploy NAC in a simple and isolated location, and helps customers experience better wireless access extension experience when experiencing the benefits of NAC. Wireless intrusion detection and defense The customer wants to detect rogue APs, such as WPA2, which can be embedded into the WLAN infrastructure. To avoid risks, especially in the retail, medical, insurance, and financial services industries, customers may find that rogue scanning does not eff

user data packet protocol on port 1900. Within 24 hours, 539 matching modes appear. This indicates that the attacker exists.Because forwarding traffic data is only a feature of some routers and switches, you need to find a way to capture and view the data. You can use VPC analysis tools from companies such as SolarWinds, NetScout, or lanw.cn, or use the aforementioned log management tools. I chose 21 Ct's LYNXeon tool because it not only analyzes the

work on one software and use the user's wireless card to sniff the wireless signal and find the problem. This system can detect fraudulent access points. Both IDs and IPs can be detected either by accessing a new access point to the network or by changing its settings to a default value or to a user-defined standard. The system can also analyze network packets to see if anyone is using hacker technology or is interfering. There are many kinds of intrusion detection and defense systems, and th

For example, take a portable Bluetooth scanner to walk in the hall, these scanners include Airdefense Company's Bluewatch, AirMagnet Company's Bluesweep, Berkeley varitronics Company Systems Bluetooth or network chemistry company's RFprotect Bluescanner. Keep in mind that you need to test three types of equipment within 10 meters. It's hard to find devices t

Since there is no specific regulation on which technology needs to be applied when complying with regulations, you have to decide what technology you need in your environment. If auditors come to check that they access your network through WLAN, you 'd better not let them get any sensitive data. The bes

If auditors come to check that they access your network through WLAN, you 'd better not let them get any sensitive data. The best way to protect your network is to use the following WLAN security measures: ◆ Do not broadcast any SSID (Service Group Identifier) from any access point ). ◆ Use 802.1x EAP (Extensi

disabling a higher rate, or even up to 54 Mbps. 5. Lack of design and Configuration Poor overall wireless design and/or configuration may cause Wi-Fi performance problems. Professional wireless field surveys should be conducted to determine the location of the appropriate access point (AP), and post-installation surveys should be conducted to verify the correct coverage. Any major physical changes to buildings and/or la s should also be adjusted. If you do not use tools such as

: one is to increase the coverage, and the other is to use a higher antenna. 3. install intrusion detection and intrusion defense systems These two systems usually work with one software and use users' wireless network cards to sniff wireless signals and find problems. This system can detect fraudulent access points. Whether it is to access a new access point to the network, or an existing access point, it is set to the default value, or does not match the user-defined standard, IDS and IPS can

much more than trying to fight those attempts to gain access to the network. For example, a hacker can create a false access point or implement a denial-of-service attack. To help detect and combat these attacks, you should apply a wireless intrusion prevention system (WIPS). The design and methods of the direct WIPs system are different, but these systems generally monitor false access points or malicious actions, alerting you and possibly preventing these malicious acts. There are many comme

insecure wireless networks, malicious attackers may intrude into your networks to obtain sensitive information. Generally, some wireless network analysis tools, such as CommView for WiFi or AirMagnet WiFi Analyzer, are used. In addition, if an attacker can obtain a physical connection to your network or a trusted user, the attacker can use a tool to perform ARP attacks, this allows him to penetrate your Ethernet 'security' control and get anything he

unauthorized access points for network access, which is very dangerous. Fortunately, most enterprises scan access point settings to avoid the emergence of illegal access points. For individual users, measures such as tracking and interception should be taken to prevent the use of illegal access points. 4. Wireless intruders: AirMagnet enterprise 8.5.1 is a multi-layer automatic defense system that can actively defend against illegal WLAN device intru

. Although all vendors claim that they can reach the maximum rate, they do not specify the 20 MHz or 40 MHz band. This is an important factor, Finneran adds, because it determines the bandwidth and the number of available channels. Another important difference is that different vendors provide different types of management software. You can make appropriate choices based on your own needs. "Some of them have very good address survey tools and planning tools, and others have very good interfaces
