Wi-Fi Networks – How to Secure Them ?
There are three basic levels of protection for a Wi-Fi network. They are WEP, WPA and WPA2 keys. WEP keys get targeted by most attacks because they are the least secure ones. It is slightly difficult to hack a WPA key since it requires more sophisticated material. The longer the password is, the harder it is to steal. At the outset one has to spy on a network. It is called ‘sniffing.’ Then one surveys the traffic and tries to get the password. In order to get a password one may launch an attack which is called ‘dictionary’.
Sometimes the internet provider is at fault. Hackers realize any development with regard to passwords and managing the networks. The default passwords given by BBox are automatically generated using the name of the network. If people do not change passwords regularly the networks will be left exposed. It is easy to hack such networks. Since most of the users are not aware of the security issues, this vulnerability continues to prevail. Hackers do take advantage of this defect of the users and gain access to the personal and confidential information of the users. Open networks or hot spots that people log into while in airports and train stations are also some examples for vulnerable networks. Hackers do find out ways to get around the required identification. They also put a ‘fake hot spot’ which tricks users into entering their user details into the fake portal. This portal, then, saves all that data and enters it into the database owned by the hackers. That data can be connect to the internet and it could be shared with others too.
Users need to be cautious about using internet especially when logging into Wi-Fi networks. It is ideal to use different passwords for logging into different sites and accounts. Accessing net from a public network or cyber café is extremely risky and it induces hacking. Signing in and logging out are the two processes which need to be done cautiously. Users also need to keep their user details strictly confidential in order to keep their accounts safe and secure.
