Key Considerations of a Business Information Security Services

 What are security services? According to ITU-TP, Security service is an intermediary service, offered by a first layer of communication, namely network, that ensures adequate security of all communications as defined by ITU-TP X. 800 recommendation. The first layer would include the security service providers (SPs), private network operators (PNOs) and other systems. All these have a role to play in securing the networks and provide security at different levels.

There are different Security services that can be offered. These include backup management, advance directive, BIND, B survivor, block management, content filtering, distribution control, key management, NDRP, security gateway, SRM, voice, security monitoring, and response plan. All these are essential for the proper management of networks. Each service mentioned above has a different function to fulfill. It should be kept in mind that the right solutions provided by the IT professionals will ensure that your organization does not experience any security vulnerabilities.

All the security services mentioned above are used to protect organizations from unauthorized access and malicious attacks. Some of these security services are also used by police officers and other law enforcement officials to protect their premises. There are various types of security services that are required for different purposes. For instance, some of these security services are used by organizations and public authorities like hospitals, colleges and government agencies.

Security services for organizations and public authorities include those guarding places like the offices, business premises, schools, hospitals, corporations, and other such places. Security services for such organizations differ according to the nature of the occupation undertaken. Most of the organizations and public authorities have security guards who guard against trespassers. The security force consists of both uniformed personnel and civilian employees, including the armed forces.

These security services are often provided by private security companies. Private security guards can be dispatched to protect commercial or business premises. On the other hand, the security guards deployed to protect houses and other residential buildings may belong to a single private security company or a group of them. A number of companies offer 24-hour guarding services to various parts of the country.

Both the unauthorized entering and the authorized leaving have their own security implications. However, security services employ different methods to counter each of these dangers. For instance, an authorized individual can give his approval to a computer system to connect to the internet or an intranet. If that particular connection is granted then there is no need for authentication because the system can establish a connection to a known source. The process of authentication is however different when we talk about the use of cryptographic security services.

Modern IT solutions provide two forms of authentication. There is the identity proofing, or identity indication which is essentially a means of verifying the authenticity of a system. On the other hand, there is the system of source authentication, also known as digital signature. The source authentication system involves the use of two factors, usually biometric data and digitally signed documents. The use of authentication services is therefore considered as an important step towards securing data, particularly financial data.

Most of the time, the companies offering the aforesaid services work with digital signature as the core of their security system. The source authentication services involve the generation of digital signatures which are to be used in order to authenticate a given document. The digital signature is however produced after the elimination of various factors. The major factor that is eliminated is the possibility of printing duplicate copies of a given document. Other than this factor, there are other factors such as the non-repudiation factor which basically states that the digital signature will not allow any changes whatsoever to the document.
