Safe Wi-Fi from Unwanted Users

Security on one side, there are many reasons why you want to protect your Wi-Fi network. A secure wireless network does not only mean to reduce bills, but it will also speed up the internet faster. This post contains some simple techniques that you can make sure that your wireless network is safe as much as possible.

WPS Saga

To ease the security of a computer, almost every new feature will have to open the new weaknesses. In such a situation, there is a case with WPS.

Wi-Fi routers typically require digital certificates or a long and complex series to protect Wi-Fi channels against unauthorized access. WPS is a feature that allows anyone to press a button or enable a software mechanism. That will add a pre-prerequisite with your Wi-Fi router to your computing device without any necessary security.

An Easy Brute Force Hack

Some years ago, however, hackers found that the WPS brute-force password was weak to guess. All the (next) versions of WPS come with a (randomly selected) 8-byte pin, which is estimated, essentially allows the connector to connect as a device. Think of the underlying weakness of 8-byte protection: Today, the minimum number of acceptable bits of symmetric cryptographic protection is 128 bits (16 bytes).

But this is very bad 8-byte pin is really only seven bytes long; The last byte is a checksum byte for the first seven letters. In addition, the first seven letters are divided into two sections: one by four bytes long, and the other only three bytes. This means that WPS is protected by maximum four bytes of security! (And you thought the lane manager hash was weak.

The attackers really have to guess only a few thousand (which usually takes four to eight hours). The most WPS-enabled router does not have projection-lock lock protection. Much new Wi-Fi router comes with some kind of security, such as pro-try lockout for a predetermined period, but often, it is not enabled by default, even worse, on some routers, even if you are using WPS Disable, the vulnerability remains active. this is insane!

Hacking Neighbors

I had disabled my WPS at my home router a few years ago, and I did not do many Wi-Fi entrance tests, so I mostly forgot about the attack vector. But with this recent incident, I decided to test most of my neighborhood. To live on an island, I know most of my neighbors

They have all Wi-Fi routers, I contacted each of them, explained the situation, and asked if I could hook up their Wi-Fi router, they all gave me permission. Within days, I was able to break into all, but one

Being a friendly computer security, I update everyone’s router firmware code (no one was up to date so far), I found any default password changed, and either disabled its WPS-feature Or has been ensured that the facility of the lockout was estimated.

The lockout feature essentially locks the WPS connection for a predetermined period of time and then automatically enables it again. The feature only locks for WPS in a few minutes, but the WPS pin is enough to guess.

Initially, I was not 100 percent sure that my friend’s Wi-Fi router was being compromised with the method of estimating the WPS pin, but after disabling the WPS facility, neighboring hackers were not getting back. I’m guessing they were quite disappointed after all, I had closed the entire neighborhood at the same time.

Protect Your Wireless Internet Network.

1) Encrypt your Wi-Fi network

When you use Wi-Fi network to access the Internet, the data you send and receive on the air can easily be snapped by anyone with the correct set of equipment. A packet sniffer can also be used by the most novice of users to sell your data. This means that a hacker can not only see which website you are accessing. But you can also get login details of your personal and professional accounts.

Encryption basically involves stopping data sent and received by using a wireless network. This means that even if a hacker blocks your data transmission. Even then it will not be able to use the information contained within it.

There are two encryption standards that you can use: WEP (Wired Equivalent Privacy). WPA (Wireless Protected Access) are old standards of WEP encryption and can now be interrupted in a few minutes. WPA is relatively new, but it still has a security hole.

Aircrack and COPETE are two free tools that anyone can easily bypass WEP and WPA encryption using Brutebars technology. WPA2 is the latest standard and it is that if you want the highest level of security for your wireless network, then you should use it. Encryption keys vary each time when a device uses the network to make WPA more difficult.

The encryption used by all devices in the network must be similar to the network to work properly. Make sure your network will be secured only as the safest device Make sure that all the devices you use use WPA2 encryption. Use a strong encryption key

2) Change the default password on your router with your password

The biggest mistake of most wireless internet users does not change the default password on their router. Hackers use those public databases that contain default passwords and user names from almost every manufacturer. This enables them to change the security settings of your router according to your needs.

Using a strong password for your router ensures that hackers and crooks can not change the security settings of your network. To change the password on your router, go to administration settings on your router’s settings page. Also, do not store passwords in browsers as they can be easily made visible.

3) Change the default SSID

Your network’s SSID or service set identifier is the name of your wireless network. Generally, the SSID is named after the router’s model as well as the model number of the router. By changing to not display this information, you can prevent potential hackers from giving additional information about your router.

4) Do not broadcast your SSID

Hiding SSID prevents unprofitable and inexperienced hackers and WiFi intruders from determining the existence of your network. It is relatively easy to hide your SSID and the option to do this is usually under basic wireless settings on your router’s settings page.

However, it is important to keep in mind that some devices running new versions of Windows will show every network, even if they can not identify its name. Apart from this, SSID is still included in the data packet in your network. Which is not making ridiculously easy with Wi-Fi for devices such as Insider, Luck and Simviz.

5) Use horror names to discourage Wi-Fi stolen

If your wireless network name is C: \ virus.exe, then most people who can access your network will not be afraid of infecting their devices. You can use your creativity to find more dangerous names for your wireless network.

6) View connected devices list

Almost every new router will have a page that displays the list of devices connected to the network. You should see this page at regular intervals that unknown devices are not leaking your network. When you see an unknown device, you can be certain that someone has violated your network. You can try AirSnare, a free utility that scans your network for unexpected Mac addresses and also looks in DHCP requests.

7) Stop guest networking

While most routers disable guest networking by default, it always pays to see that. You can not accidentally enable guest networking to allow others to access your network.

8) Enable mac address based filtering

Media Access Control or MAC Address identifies each device connected to your network. The MAC address is an alphanumeric key separated by colons. Enabling Mac address-based filtering only allows devices with special MAC addresses to access your network. You need to enter the MAC address of each device that. You want to allow to connect to your network on your router’s settings page.

This prevents anonymous devices from connecting to your network even if they know your password. To find your computer’s Mac address. Open a command prompt and execute “ipconfig / all” in Windows based computers without quotation marks.

While this inexperienced user can be prevented from accessing your network. Experienced hackers and advanced users can use wireless network analyzer like NMAP and then change their computer’s MAC address.

9) Keep your firmware up to date

Router vendors release firmware updates on a regular basis and post them on their website. You should sometimes look at the manufacturer’s website to see if a new firmware update has been issued. New routers will automatically notify you when new firmware is available

10) Reduce wireless signal range

If you reduce the limit of your wireless network. Then common sense tells you that it will stop hackers located at a distance from detection of your network. The advantage of this is that if hackers do not know that. A wireless network is present, then they will not try to break it. You can place your router in those places that will block Wi-Fi signals. Although this technique is beneficial, for hacking into your network.

A hacker will have to use only one large antenna to take your router’s signals. Apart from this, reducing the range of your wireless network can cause problems for real users.

11) When not using your internet network, turn it off

It is self-explanatory if you are not using your network. By turning it off and protecting you from hackers in extra time to try and hack into your wireless network. Although every time you are not using it, it may be impractical to shut down your network. It is still appropriate to do this during the extended period of non-usage.

If you follow all these techniques. Then your Wi-Fi network will be highly protected and hackers will have a hard time in it.
