Furthermore, there are reports of substantial losses due to untrained employees exploring the corporate network and accidentally corrupting data. Because employees and customers are invited into the computer network or system, security measures need to be even more intensive internally than those necessary to protect against external tampering threats. Despite the ever-present threat of tampering, there are measures businesses can take to protect themselves from unauthorized access and other destructive acts by crackers as well as employees and other authorized users. The most popular defense tool is the firewall for your computer or network which is analogous to a home security system. The firewall is fitted to your system and alerts you when that security perimeter is breached.
Encryption is another type of security measure used to protect data and information.
Encryption is generally used when information is transmitted over the internet and codes the information to keep unauthorized persons from being able to read the data. These are just two of the many types of security measures available. There are much more sophisticated and expensive security tools available and each type is aimed at preventing one or more types of tampering. The greater the amount or value of the data, the more sophisticated the security measures must be. Just as using the internet may involve risks, protecting your computer, website or network may have its disadvantages as well.
