Cybersecurity, computer security, or information security is basically the protection of networks and computer systems against unauthorized access, destruction of or damage to their physical hardware, information, or digital data, and from the interruption or misdirection of their services. It also involves the identification, prevention, and response to security threats. A wide range of companies in different sectors, ranging from financial institutions to Hollywood studios to high-tech businesses, are making use of this field of expertise.

Different types of threats have been plaguing networks for a number of years now, and in response, several different types of approaches have been made. One of these is Application security which, in the widest sense, aims to protect information and prevent hackers from gaining access to it. Another is Web security which aims to protect websites from hackers who want to infiltrate your system so that they can steal personal information. Then there is mobile security which aims to protect mobile devices like smart phones and PDAs from hackers.

There are a number of ways in which you can protect yourself from cyber threats but there is no single solution that can be applied universally because the different threats have different origins and varying degrees of seriousness. Some of these are easier to tackle than others. Hence, you need to understand the nature of each threat and choose a suitable measure for protecting computer systems accordingly. There are plenty of available sources that can be consulted on the matter but it is important to remember that no single source can provide a complete picture of the cyber threats that are posing a problem today, and hence the need to adopt a comprehensive approach to protecting yourself.
