Making Sure Your Wireless Home Network Is Secure

Making Sure Your Wireless Home Network Is Secure



Making Sure Your Wireless Home Network is​ Secure
As more and​ more people make the​ switch from wireless networks to​ secure networks in​ their homes, there are a​ whole new range of​ security issues to​ be aware of​ .​
Too often people set up their wireless network and​ forget about the​ security implications .​
However, this can be a​ serious oversight as​ people can easily access your personal information and​ is​ a​ common cause of​ fraud .​
In this article we advise you on some of​ the​ steps you can take to​ make sure your wireless network is​ secure.
Almost all computers with recent operating system and​ wireless capabilities will have the​ option to​ turn on a​ built in​ firewall .​
If you are using an​ older operating system you may want to​ install a​ third party firewall .​
Although this alone will not stop third parties from accessing your network, it​ will act to​ secure each computer on the​ network from unwanted network requests .​
Creating secure user accounts is​ also advisable .​
Weak username / password combinations are exploitable should a​ hacker try to​ gain access to​ your networked computer via your wireless network .​
Stronger passwords will generally contain mixed case alphanumeric characters .​
You can easily find advice on writing secure passwords on the​ internet.
Most wireless routers allow you to​ access their configuration with your web browser .​
Be sure to​ change the​ default username and​ password that allows you to​ administrate your router to​ prevent unwanted access .​
If you do not, almost anyone could breach your network.
In addition, every network capable computer will have at​ least one MAC address that identifies it​ on your network .​
Granting access to​ your wireless network based on MAC addresses will filter out unwanted users and​ network capable devices .​
It is​ not foolproof, but it​ will discourage most would-be hackers.
Wireless routers also broadcast an​ SSID which is​ basically a​ name of​ the​ network that appears when a​ computer picks up its signal .​
By default, this will usually be the​ name of​ the​ manufacturer of​ your wireless router .​
Many companies identify their networks using the​ SSID and​ it​ can be a​ handy way to​ identify Wi-Fi hotspots when you are out and​ about .​
However, for​ the​ sake of​ your home network it​ is​ not really necessary so it​ is​ a​ good idea to​ stop broadcasting it​ entirely.
It should also be possible to​ encrypt the​ data that is​ sent between computers on your wireless network .​
However, you must ensure that all computers have the​ same encryption settings.
One of​ the​ main reasons that wireless home networks can have security issues is​ because the​ signal can often reach beyond the​ boundaries of​ your home .​
One major financial institution recently lost millions of​ credit card records because it​ did not have its wireless system properly secured .​
Another method that is​ commonly used to​ secure wireless networks is​ static IP addressing .​
IP addresses are often assigned automatically on wireless networks .​
However, networks are much more secure if​ the​ IP addresses of​ all computers on a​ network are set by hand .​
This is​ not foolproof but will keep out casual hackers.
If possible, place your wireless router in​ a​ part of​ your house or​ apartment where the​ signal will not travel too far beyond the​ boundaries of​ your home .​
If your home overlooks a​ street, do not put your router too close to​ this part of​ your home .​
In addition, if​ you are going on vacation or​ are going to​ be away for​ an​ extended period of​ time you should turn your router off while you are gone.
Even if​ you do not have a​ wireless network in​ you own home, it​ is​ important to​ know how to​ keep your notebook secure when you are out and​ about .​
You should make sure that your notebook does not auto-connect to​ other wireless networks .​
By default, both Windows and​ Mac OSX will display a​ warning before connecting to​ unknown networks and​ both will allow you to​ identify which networks you trust for​ automatic connection .​
When you are connecting to​ outside networks that you do not know, make sure that your firewall is​ turned on.
Too many people overlook the​ importance of​ securing their wireless networks .​
The steps outlined above should not take long to​ implement .​
While they may not guarantee 100% security, they are likely to​ deter any would-be hackers.
These are just some of​ the​ steps you can take to​ make your home wireless network more secure .​
There are millions of​ networks out there that are very poorly protected so if​ you take the​ time to​ put even a​ few of​ these safeguards in​ place you will most likely deter any would-be hackers.
