How To Check Unauthorized Access to Wi-Fi®

Wireless networks are gaining popularity with each passing day and more and more people are getting rid of the old Ethernet cables and getting a wireless network installed. Ethernet cables are considered to be the safest way of communication because no one can illegally hook a cable into your router and steal your network resources, but when it comes to wireless networks this can be easily done if proper measures are not there. Wireless signals are broadcast equally in all directions and anyone who somehow knows the password of your wireless network can easily access the Internet and your network without you even knowing the same. In this post I will let you know how to identify if someone is accessing your home wireless network and how to make it secure again.

Identification

Every router has a few LEDs on its front. One of these LEDs is for the Internet. This light stays solid if Internet is not in use and it flashes if information is going or coming from the Internet. The easiest and quickest way to check if someone is connected to your router or not, is to check the status of Internet LED on the router after turning all your home computers off. If it is flashing then somebody is definitely connected to your router and is using your resources.

We mostly name our computers by our own name so if the person who is illegally using your network has also named his computer as his name then you can even come to know about the same. Let us see how.

Step 1: Open the Router console by typing ‘http://<IP of your default gateway>’. This will take you to the router set-up page also known as router console.

Step 2: Enter the username and the password and enter into the console.

Step 3: Go to the Status section of the router. It may be named as something else in different routers but you need to look for it. Here in the status window router displays all the devices which are currently connected to the router. You obviously will identify your home devices and computers and can easily make out the one which is not in your house.

Step 4: This list displays the IP address, MAC address and even the computer name which is connected to the router. So this way you can come to know about the name of the computer or person who lives nearby and is illegally using your computer.

Fix the problem

Once you know that someone is using your network then you can take measures to stop the same. First would be to change the security key and make it hard to guess. This will at once disconnect the unauthorized computer and he will not be able to connect again until he knows the new password. Second best thing will be to note down the MAC address from the status screen of the router and block the MAC address completely in the router. This ways even if the person knows the security password, still he would not be able to connect to your network.

How to Keep Your Wireless Network Secure

While most people concern themselves with the advantages of a wireless network and the benefits they receive from having an Internet connection, very rarely do they give enough thought towards securing their network. A wireless network, despite the several advantages it boasts of, is dangerously prone to outside threats in the forms of hackers, malware, viruses which can harm the network in a big way.

Network technicians can talk on lengths about the different ways in which one can secure his network. However, there’s a specific step by step procedure that one needs to follow to ensure that the system is protected and secured against outside and unauthorized access.

Instructions to keep your Wireless Network secure

The step by step procedure begins by keeping the instruction manual with you despite all odds and proceeding further with the following instructions.

Step 1: The first step involves getting into the control panel of your router, which can be done by opening the web browser and typing ‘192.168.1.1’ in the address window at the top. Note that this is only the default IP Address which can otherwise vary according to the manufacturer. Read your instruction manual for the exact IP Address or contact the manufacturer if you do not have the manual.

Step 2: After entering the IP Address and hitting Enter, you will be taken to the Login page where you are required to enter a Login name and a Password, the information which is present in the manual as well. In majority of the cases, the Login name and Password are entered as ‘admin’ or the password field is left blank, while users continue with ‘admin’ as the Login name. Once you have managed to enter the correct information, it is recommended to change the default information because the hackers usually are aware of it.

Step 3: When you enter the configuration page, you need to turn on the encryption where you can either use WPA or use a 128-bit WEP. Choose a password of your choice which you can remember however don’t choose something that can be too obvious to the hackers.

Step 4: The default SSID or the network name is a common target for third parties to access the network. It needs to be changed immediately to ensure a powerfully protected and secure network.

Step 5: MAC Filtering is an option in which you can enable only those computers to access the network that you know about and want to share the network connection with. For the purpose, you need to obtain the MAC Addresses of all those computers and enter them into a configuration screen of the router or the wireless access point. Then the filtering option needs to be switched on to end the procedure.

Apart from the above instructions users may follow, they also need to purchase and install any of the famous Antivirus software, examples of which are the Norton Antivirus, McAfee, Avast, AVG and Kaspersky. These help to keep the system safe from viruses, worms and Trojans which find their way into the system through open ports and damage the disk drives.

How to Secure Your Wireless Network

From Arpanet to Intranet and from Intranet to Internet, the evolution of Internet brought about a revolution in the world. An era of IT and communication was  born out of this revolution. The revolution in which Internet access saw a new definition and the word “approach” towards the internet access completely altered. Earlier the approaches were like dial-up connection, Ethernet cable and then knocked the world of “Wireless Network”. Although, the “Wireless” network era looked for its worth, but the worthy wireless network has dozen of evil eyes on it. Evil eye balls can be in the form of a hacker, malicious programmer or software developer.

Is there an answer to such menacing elements? Yes there is, you have a bundle of methods to abridge such intrusions.

Instructions:

Step one

Access your router’s homepage by typing its IP (Internet Protocol) address of your router in the address bar of your web browser. The IP address for different company routers is different and they must be somewhat of this kind like 192.168.1.1 or 192.168.1.22 etc. When you hit the above mentioned IP address a window will be prompted. This window will ask you to enter the username and password of your router. If the router adheres to default settings then the username will be “ADMIN” and the password will be “ADMIN”.

Step two

Find out the basic wireless settings on the prompted homepage and Hit the (Wireless Network name) that is the SSID. Disable the SSID wireless broadcasting channel and thereby, choose a proper mode of wireless channel.

Step three

Now you will go for encryption for which you will be required again to visit the wireless security tab and choose the WPA or WEP encryption format. Bear in mind WPA is the better security mode as compared to WEP one and choose the 64 or 128 bit encryption. Enter a password or pass phrase that will serve as key when you will be installing the wireless network software on your system. An alphanumeric WPA or WEP key must be created and changes must be saved or applied.

Step four

Now you are going to find out the MAC address of your network which you can find this ways. Click on “Start” then “All programs” tab and followed click on the “Accessories” tab. In the menu prompted you will find the “Command Prompt” tab click on that. A on the prompted window type “ipconfig/all” and track the physical address of your network, that will be the MAC address for your computer. Find the MAC address entering bar from the wireless network and check the “restrict” access option.

Step five

Disable the remote management or administration by click on the management or administration tab under the “settings” section of your router.

If you have followed the above process properly, then ensure that your wireless network will then remain secure. All you need to do is to install the wireless software, enter the WPA or WEP key and enjoy surfing.

How to Keep Your Macintosh Secure

Accessing Internet at home or at office isn’t only about logging in to the web browser and start connecting. Securing the connection is mandatory. This involves not only setting up a network with security settings pre-installed but also to adjust them to avoid troubles and being cautious against possible dangers. In a common wireless network, the security settings are often the WEP Password or WPA Personal by default. However it depends on the setup. To modify these settings, one needs to know what the exact security type for the network is. This is ensured so that proper configuration can be done. The settings can also be enhanced by turning on the Firewall protection. It prevents other unauthorized users from accessing your personal information over the network.

Instructions for adjusting the Security Settings for a Wireless Network on a Macintosh Computer

Step 1: Click on the ‘Apple’ icon present at the top of the screen. From the drop down menu, select ‘System Preferences’.

Step 2: In the next window, look for the ‘Internet and Wireless’ section and then select the ‘Network’ icon under it.

Step 3: Click on the ‘Advanced’ tab. Then select your network name and click on the pencil icon so that you can edit the network.

Step 4: Then click on the drop down menu to go through the available security settings for the network. You can select the security type as desired. Then enter the password and click on’Save’.

Step 5: In the upper left corner of the screen, click on the ‘back’ button. Look under the ‘personal’ section in the screen and then click on the ‘Security’ button.

Step 6: It involves turning on the firewall for protection. Click on the ‘Firewall’ tab, followed by a click on the ‘Start’ button to turn it on. Then the ‘Advanced’ button needs to be clicked.

Step 7: The box next to ‘Enable stealth mode’ needs to be checked. Click on ‘OK’ and then on the red button that is in the upper-left corner to exit Preferences.

Apart from following the above steps for wireless security, there are some guidelines that should be kept in mind if one has a Mac running MacOS X. Even though the Macintosh has an in-built firewall, you can spend additional money on an enhanced firewall like DoorStop. It provides detailed information on the users who’ve been trying to access the system while the software in use. One must keep up with software and browser updates if a third party web browser such as Firefox is being used. Such software updates have in built security patches. Also, Mac software must be downloaded only from well known and reputed sources. Passwords must be saved in a password protected application like data Guardian. If the system isn’t in a physically secure location, you should log out after you have finished with whatever you were doing. Despite there being measures which need to be taken to enable Mac security, its in-built defenses are many. It doesn’t get PC viruses and doesn’t need constant alerts and sweeps to keep away malware.

How to Secure Your Wireless home Network without Passwords

How to Secure Your Wireless home Network without Passwords

The security of a home wireless network is very important. Everyone wants a seamless and secure network all the time. Passwords are the most used option for security. But sometimes it is very annoying to play with those long passwords. Now you can secure your home network without using passwords. There is an easy way to protect your network without using passwords. Often most of the people overlook this way of protection, this is to use MAC address filter.

Steps to secure home wireless network with the use of MAC address filter

In every device it may be a printer, network card or USB device has a unique MAC address. MAC address is an acronym of media access control address. The unique address is a 16 digit address in the format 00:1d:e5:7h:3f:8h:0g:3a. First decide which item you want on your network every device has a unique address. To get the unique MAC address you just have to go to each computer. First step is to open run command and type ipconfig/all, when you enter it will list the entire network adapter. You just have to get the MAC address of the wireless card. To get the MAC address of the wireless adapter, just see the sticker on the device. List all the devices, you want on your network and get their MAC address. You may get on their sticker and in the case of game consoles; you have to find it on network configuration screen. Now you are done with collection of all the MAC addresses, go to control panel using the IP address of the format 192.168.0.1. Now go to the advanced network configuration, and apply the filters. But we recommend you to collect and ensure about each MAC address and before applying filters on your computer, just be sure about adding the MAC address on the computer.

Now you have to add your own computer address by clicking on the clone MAC address and doing same trick, you can add other devices also on the home wireless network. Now you are finished with adding all the Mac address on the network, just enable the MAC address filter. Now your home network is secure without passwords, disable all the passwords. No one can add their personal device without enabling the MAC address. Now just relax because your home wireless network is secure without passwords.

Tips and warnings

These instructions are surely going to help you, but you have to keep some points in mind while doing so. Try to ignore non- wireless devices while enabling the Mac address filter. By doing so, it will always allow you to connect to the router. We recommend you to leave one device disabled, you can test MAC filters on that device and you can also add the device when you want.  Before enabling the MAC filter, first ensure that your own computer is added to the network. After enabling the MAC filter, you are not allowed to connect your computer.

How to Secure your Network Connection

Here are several ways to make your computer more secure.

Update your computer frequently

Updates provide extensive protection to PCs on your network. There are two types of ‘updates’ – Automatic and Optional. Automatic updates ‘automatically download and install recommended and important updates. Optional updates are not automatically downloaded or installed. Recommended updates refer to updates that can improve PC performance and concern non-critical issues. Important updates are those that boost security and consistency

Avoid staying logged on as an Administrator

Logging onto your computer as a standard user instead of as an administrator is safer and recommended while using programs to access the internet e.g web browser/email. Many viruses/worms can’t be accumulated and run on your PC unless you’re logged on as an ‘administrator’

Utilize firewall

 

Hackers, worms or other malware are frequent visitors to your computer. Firewall prevents these from accessing your PC via internet/network and prevents your PC from transmitting the malware to other PCs. Additionally, it is important to ensure your firewall is updated regularly.

Install and update Anti Virus Software

We have talked about hackers and worms affecting your computer. Although firewalls protect your computer from these, they are however not specifically designed to provide protection against viruses and that raises the need to install Anti-virus software. Viruses can be transmitted in almost any form especially email attachments, files on DVD/CDs, downloaded files from the internet and online shops. Antivirus software requires frequent updates to remain effective and scanning your PC regularly is also highly recommended.

Use a router to share web connection

Routers are good devices for your PC if you share an internet connection. These are generally incorporated firewalls, network address translation (NAT) and various other features which aids your network in protection against potential hackers .

Take advantage of a network security key

Network security key is useful because it turns on encryption which encodes the data broadcast between your PC and your wireless router. It also blocks people from connecting to your network without the security key, which helps prevents attempts to access your network/files without your permission. From the various options, Wi-fi Protected Access (WPA or WPA2 ) is a recommended encryption method.

Change default admin/password

Most manufacturers set router to default name and password which someone can readily access without your knowledge – to avert the risk, change the default admin/password regularly. It is also important to create a good password that is strong, distinct and long. . If you forget the password, most routers have a reset option that will restore all the settings to defaults

Change default SSID

Service Set Identify or better known as SSID is a wireless network on routers and access points. Manufacturing firms use the same SSID in all routers/access points. It is recommended that you create a new password in order to avoid overlapping with other wireless networks using default settings. Default SSID may indicate to a hacker that other options (such as password/username) may be set to default.

Positioning your router/ access point

In order to limit your wireless signal from extending beyond places you prefer, position your router/access point near at the center of your home/office rather than near window or outside wall.
