Network Security

IT Security is important and necessary for all businesses. It saves your important data and prevents any data breaches to unauthorized third parties. It is an organization’s ethics and responsibility to protect both its customers’ and vendors’ personal data such as contact number, address and credit card information.

Yet IT security is a huge challenge for all organizations, especially for SMEs who could not effort to hire full-time IT professionals to handle and develop a proper security system. The technology behind hacking also gets better, which forces organizations to reinforce its existing security system to match up to the improvement in hacking technology.

The recent hacking incident – using a tool called WannatCry 16huat$ (a kind of Ransomware) – is one of latest security threat that blackmails your data and forces your organization to pay in order to retrieve your information.
