In the early years of the internet, it was often recommended, when addressing the question of security in the net, to disconnect the connected computer to the Internet from the rest of the working processes. That way, the malware from the net would not corrupt the data of the companies. It used to be a simpler and more efficient suggestion, obviously no longer practicable in the current era of almost total connections: rarely can a firm avoid having a computer network. However, the constant connection to the Internet – also from mobile devices – makes these nets easily vulnerable and this is why sensitive data must be more and more protected.
What are the threats?
Cybercriminals use unprotected web protocols to launch their attacks. These protocols are responsible for the exchange of data between computers and net providers, the most popular being the TCP/IP protocol. Under an insufficient protection, what is known as man-in-the-middle attacks can be started. If an attacker has obtained access to a computer network he or she can stand between two communication partners without being noticed. For the full article click here
