Update all programs to prevent them from malicious attacks. Using a secure web browser with add-ons built in that help prevent malware attacks. A computer being secure depends on a number of technologies working properly. A modern operating system provides access to a number of resources, which are available to software running on the system, and to external devices like networks via the kernel. All Windows operating systems come with the ability to create profiles with is a built in security features. As well, they have Windows Defender built in, however, the individual has to turn it on in most cases.

To establish identity there may be a process of authentication. Often a username must be quoted, and each username may have a password. Other methods of authentication, such as magnetic cards or biometric data, might be used instead. In some cases, especially connections from the network, resources may be accessed with no authentication at all (such as reading files over a network share). Also covered by the concept of requester identity is authorization; the particular services and...
