Wireless Network Security 20, Wireless Network Security

Big brother, how can you see that you have this tendency? b Khan.

This security is still there, but if you want to crack it, it's still not too difficult, and there is software on the Internet that specializes in cracking wireless passwords

Most people won't go to the trouble of cracking your password for the sake of that momentary network.

Enter the route yourself to see if there are any users other than you, if there is, it is stolen. In addition, it is best to bind the route to the mac, and only your own computer can connect to it. Finally, the password is set to complex points, using characters, numbers, and letters.

In this way, even if there is a cracking tool, there is no place to start.

Top 7 wireless network security threats.

1) Information replay:

Without adequate security precautions, it is vulnerable to man-in-the-middle spoofing attacks using rogue APs. This kind of attack is difficult to avoid even with protection measures such as VPNs. A man-in-the-middle attack double-spoofs both the authorized client and the AP to steal and tamper with information.

2) WEP Hack:

Nowadays, there are some illegal programs that are very common on the Internet, which can capture the packets located in the AP signal coverage area, collect enough packets encrypted by the weak WEP key, and analyze them to recover the WEP key. Depending on the speed of the machine listening to the wireless communication and the number of wireless hosts transmitting signals in the WLAN, the WEP key can be exploited within two hours at the earliest.

3) Network Eavesdropping:

Generally speaking, most network communications are in plaintext (non-encrypted) format, which allows an attacker within range of a wireless signal to monitor and crack (read) the communication. Since intruders do not need to physically connect eavesdropping or analytics devices to the eavesdropped network, this wireless network security threat has become one of the biggest problems facing wireless LANs.

4) Impersonation Attacks:

An entity pretends to be another entity to access a wireless network, known as an impersonation attack. This is the most common way to break into a security line. In wireless networks, mobile stations are moved to control centers and other networks.

There is no fixed physical link between the mobile stations, and the mobile stations must transmit their identity information over the wireless channel, and the identity information may be eavesdropped when transmitted in the wireless channel, when an attacker intercepts the identity information of a legitimate user.

The user's identity can be used to infiltrate the network, which is known as an identity spoofing attack.

The data is obtained through the network eavesdropping tool, so as to further obtain the static address pool that the AP allows to communicate, so that criminals can use MAC address camouflage and other means to reasonably access the network.

6) Denial of Service:

An attacker may flood an AP and cause the AP to deny service, which is one of the most serious attack methods. In addition, an attack on a node in mobile mode that keeps it serving or packing** so that it runs out of energy and can't continue to work is often referred to as an energy consumption attack.

7) Post-service repudiation:

Post-service repudiation is when one of the parties to a transaction denies its involvement in the transaction after the transaction is completed. This wireless network security threat is common in e-commerce.

The most dangerous are the people who are still using WEP.

1. Others use your network, (annual subscription) you lose network speed, (traffic online) you spend more money.

2. Hack into your computer and steal all the information in your computer (personal, bank card, etc.......）

3. Hack into your computer, record everything you can see through the camera, and then blackmail you.

4. Some things that I don't know, but will also cause bad consequences.

The most we can encounter is the first type.

Top 7 cybersecurity threats in the IoT world.

Wireless network security risks are wireless network security is not an independent problem, enterprises need to realize that they should deal with attackers on several fronts, but there are many threats that are unique to wireless networks, and the following is some relevant information about the threats that exist in wireless networks for your reference.

Security threats to enterprise wireless networks.

1. Insert attack.

Insertion attacks are based on the deployment of unauthorized devices or the creation of new wireless networks, often without going through security processes or security checks. The access point can be configured to require the client to enter a password when accessing. Without a password, an intruder can connect to the internal network by enabling a wireless client to communicate with the access point.

However, some access points require the same access password for all clients. It's dangerous.

2. Roaming attackers.

Attackers don't have to be physically located inside a corporate building, they can use a network scanner like a tool like Netstumbler. Sniffing out a wireless network on a laptop or other mobile device on a moving vehicle is called "wardriving."

Walking down the street or performing the same task through a business** is called "warwalking".

3. Fraudulent access points.

A fraudulent access point is an access point that is set up or exists without the permission or knowledge of the wireless network owner. Some employees sometimes install fraudulent access points in order to circumvent the security measures already installed by the company and create a stealthy wireless network. This clandestine network, while largely harmless, can construct an unprotected network that acts as an open door for intruders to enter the corporate network. What?

The main thing is that it is easy to have network vulnerabilities and be easily hacked, and you can use the 360 free wifi tool when you connect to the wireless network, which can be protected.
