How to make your Computer Network Secure?

Networking allows you to share Internet data and access files and folders across systems easily. But one does not want to share his information and data with just anyone. With the help of a wireless network, your information is moving through the air medium, not physical wires, so anyone within the range can intrude your network. There are five substantive security measures you should take to procure your wireless network.
Change the default connection password:
All the Access points and routers have a default password set by the company. You will be asked for a password whenever you want to make alterations to the network settings. Hackers are aware of these default passwords and will seek them to have illegal access to your wireless device and alter your network settings. To avoid any unauthorized alterations, change the password and make it hard to guess.
Modify the default SSID:
Your wireless network devices have a default SSID (Service Set Identifier) which is set by the company. The SSID is the name of your wireless network, and it can be up to the length of 23 characters. Modify your network’s SSID to something unique, and ensure it does not refer to any networking products you own. As an extra precaution, make it a point to modify the SSID regularly.
Enable WPA Encryption:
Encryption allows security for the data that is being communicated over a wireless network. Wired Equivalency Privacy (WEP) and WiFi Protected Access (WPA) extend unlike degrees of security for wireless communication. WPA is addressed to be safer than WEP, because it makes use of the dynamic key encryption.
Disable SSID broadcast:
Automatically, most of the wireless networking devices are typeset to broadcast the SSID, so any person can effortlessly join the wireless network with just this info. This is advantageous for the hackers, so unless you own a public hotspot, the best idea is to disable the SSID broadcast. You certainly will believe that it is handier to broadcast your SSID so that you are able to click on it to join the network, but in addition you can configure the devices on your network to automatically connect to a specific SSID without transmitting the SSID from the router.
Enable MAC address filtering.
Some routers provide you the power to enable MAC address filtering. The MAC address is a distinct series of figures and letters allotted to every networking device. With MAC address filtering, you can determine which computers can obtain access to your network. It would be quite difficult for a hacker to find your network using a random MAC address.

In the age of globalization, computer network plays a crucial role. Today, most of the companies operate from multiple locations, sometimes from different countries or from different cities in the same country. In any industry, most of the work is done with the help of computers; therefore, maintaining a computer network becomes extremely important. The computers could be connected with the help of a Local Area Network or through Wide Area Network. Information is sent through this network which could range from two to thousands of computers. Networking of these computers is extremely essential for not only helping the employees to communicate, but also to send and received information. With these large networks in place, it has become extremely important to maintain a good computer network.
Maintenance of computer networks in a proper condition is extremely important for the smooth operation of the day to day operations. For any computer network, server plays a crucial role. It is called as heart of the network. Ensuring a good quality and reliable server could help you to avoid many problems related to the network. Server is also a place where the data and information are stored. Therefore, it is also important to have a back up server in place so that if the primary server fails or does not work, the employees can be asked to switch to another server. This will also ensure smooth conduct of the business without any disturbances. Always ensure that the operating systems of the computers in the network including the server receive regular updates at the right time.
Your computer network is also required to have a up-to-date antivirus system and firewall to minimize the chances of virus attacks that can be caused due to internet or through other network. As far as possible, restrict the usage of internet and removable disks like USB drives, or CD drive.
Computer networks are the backbone in today’s world. If the networks are attacked, your businesses could suffer and you may have to incur huge losses. So maintaining them in proper condition would definitely decide the profitability of your business.

Common Computer Netwoking Problems

With expansion of business, there is a need of an intelligent and fast network of computers within a workplace. For that careful planning is required. Even when you have your network ready, you may encounter few networking issues in daily life. Here I have jotted down common networking issues encountered and methods to solve them.
Duplication of IP addresses : Every computer or a laptop on a network has a IP address. This is a unique set of numbers used to identify a particular machine. At times due to human error, two machines in the same network can get assigned the same IP address as a result “IP conflict” can occur which may hamper performance of those two machine on the network. To tackle that, all you need to do is to change IP address to make it unique within your network.
Problem in connectivity : Connectivity problem is the most common problem encountered in any network. It can occur due to number of causes ranging from loose connection to improper configuration of hubs, switches or routers. First thing to be done when you encounter connectivity problem is to check for the networking connection for your PC. If there is any disconnection, you will need to reconnect and test it. After checking the physical connections of your computer, check if common device’s (switch, hub or router) cabling is properly connected and you can view green light at the connection port. If there is still connectivity problem, then you may need to configure hub, router or switch as the case may be.
Software-related problems : Once all the physical aberrations have been taken care of, but your network is still not responding; you need to check the network for any kind of a software related problem which might range from WINS, DNS to even registry issues. You may need to alter the configuration or reinstall the software that has malfunctioned.
Slow connectivity : If you notice that your network is taking exceptionally long to function and the speed is very slow, it might be resulting from numerous network collisions. In poorly planned networks, this problem is quite frequent as the network gets flooded due to excessive simultaneous transfer of data and information. This problem can be tackled by using zipped and compressed files and folders to transfer heavy data and by using data travelers. This reduces the pressure from the networks and boosts its speed and functioning.
These are few common networking issues that are encountered in daily life. For expert networking solutions feel free to contact Centex Technologies.
