Despite many benefits the Internet brings some risks, for example phishing, piracy, plagiarism, spreading malicious software, cyberstalking, spreading offensive material, etc.
The most common type of crime involves malware (malicious software) –viruses, worms and Trojan Horses.
There is a variety of security measures which can be used to protect both hardware and software, for example: Controlling physical access to hardware and software, backing up data and programs, using passwords to control access to a network system, installing a firewall, encrypting data, using signature verification or biometric authentication, using antivirus programs and downloading updates, ensuring that all software is free of viruses before it is installed.
