There are essentially two main types of computer security – software and hardware security – with several other categories within them. Software security generally consists of server protection and security, system security against viruses and other malicious software programs, and data security through theft prevention and safe computer practices. Hardware security generally consists of physical devices, including server mainframes, computers, and external or portable memory and storage devices.

Most types of computer security practices or considerations can easily be seen as related to software or hardware security. Software security refers to the ways in which attacks can be launched on data and software streams, without the physical interaction of different devices or hardware. One of the most important security measures for many companies is network and server security. This generally refers to the ways in which a company secures and secures its networks and any internet services it may offer, including business websites and private data storage.
Good virus protection software is an important component of having a safe computer.
Other security issues involving software include problems with malicious programs such as viruses or spyware. These programs can enter a system and remain invisible, causing damage to data, providing attackers with access to remote systems, and otherwise creating problems for businesses and individuals. Data theft is also a serious security consideration for many companies and individuals, as it can result in the loss of information that could be used for identity theft and the compromise of corporate secrets or private information.
Theft prevention is a basic type of computer security.
Hardware security refers to practices related to how physical devices and computer hardware are handled and supervised. Physical server mainframes that often host multiple networks and Internet sites can be damaged, resulting in data loss, or they can be physically attacked in an effort to steal information directly from the system by transferring data between devices.
Computer security includes software that scans for viruses and blocks access by unauthorized users.
Many companies and individuals should also be aware of considerations for different types of computer security and physical theft. As computer technology improves, memory and data storage devices become smaller and smaller. This means that someone could steal a single computer tower or laptop from a company or a person’s home and potentially obtain vast amounts of data and information that could be private. Small data storage devices such as thumb drives should also be protected as one could carelessly forget about such a device in a public computer terminal and create a very real opportunity for data loss.
