What is a security domain?

A security domain is a term used to concept of any grouping of computers, networks or elements of information technology infrastructure that falls into a particular security protocol. The domain is determined as a limited unit of those elements, which then have one method of verification for access to elements in the safety domain. As this term is of such a conceptual nature, it can be applied to a wide range of information technology elements (IT) such as a collection of websites, communication network, a group of computers in the room and even a combination of any or all of this website. This can be processed in several different ways, such as a software agent on a web server or a separate proxy server. With a software agent, each web server has a small software program installed that receives authentication information from another server. The software on the web server captures the web request and then checks the server to manage access to POrthole before enabling or denying access to the web or a specific website. On the other hand, with Proxy Settings, the proxy contains access permissions for web servers that protects, captures the requirements for these servers and only allows the requirements that meet the correct security criteria.

In another case, the term of the security domain is often used with the service directory services. One common examples is Active Directory® Microsoft®, which uses LDAP and Kerberos Authentication System to create a single point. In this case, the domain is a real computer network consisting of any number of computers, servers and software program. Access to these elements is then processed by the Active Directory® system, which even allows you to determine separate safety domains in a single, larger administrative domain.

Vyovered information is also often maintained in a specified security domain. In this case, the safety domain is composed of any or all of the above elements, but the only source of verification may be of a different nature. One example is known as Secret Internet Protocol Router Network (siprnet) used by the United States government. Sippnet is a highly introduced set of interconnected networks that basically reflect the Internet. This type of security domain, part of a network of defensive information systems, still uses all the same technological protocols as the Internet, but without connection to the real Internet itself.
