When people travel with their laptops outside office, others can access it; get stolen it. In this way many companies have lost sensitive information and confidential data. Using laptops on public wireless networks gives hackers a golden opportunity to break into not only the machine, but also into the corporate network to which the machine is connected. When a laptop with wireless capabilities is connected to a wired network, it can allow hackers to break into the wired network. Here are some basic tips to ensure that your laptop and the data on it don’t fall into the wrong hands.

Prevent physical access : If it is possible, you should avoid leaving your machine unattended when you’re outside office. You should also not let anybody use your machine, for however short a period of time, otherwise it is a co-worker who has legitimate reasons for doing so.

Guard against spyware : Spyware is the main cause of data theft from laptops and corporate networks that are accessed through infected laptops. You should avoid to install any peer-to-peer program or shareware on the laptop because these are known to spread spyware. At the time of downloading anything from the Internet, be sure to read the End User License Agreement carefully, ensuring that you are not downloading any spyware alongside. Avoid pirated software which is a way to get spyware on to your machine.

Take regular backups : It is most important to take regular backups of the work you do on the laptop because the risk of hacker attacks over wireless networks and even physical theft of the laptop is higher.

Use full-disk encryption : Many encryption utilities enable you to encrypt the data on your hard drive and even on USB pen drives. You must use encryption to ensure that even in the worst-case scenario of your laptop getting stolen, the thief cannot access your confidential data.

Use a firewall : Anti-virus, anti-spyware software and a firewall, are very essential to a laptop, because you may be connecting to the Internet via public hot spots, which make your laptop more vulnerable to hacker attacks.
