A security service is a crucial service, offered by an information layer of communication such as the Internet, that ensures proper security of all networks or of important information transfers as decided by ITU-T. Recommended by the ITU, these security services are available in different forms, including desktop security services, web security services and other forms as per individual requirements. Desktop security services include application security services and firewall services. Web security services include firewall, antivirus security services, and content filtering security services.
It is to be noted that all security services are directly or indirectly related to IT security. The security services protect a system from all attacks and hazards to the information stored or communicated by the system. The attacks could be physical or logical in nature and therefore the security services should cover all the aspects such as monitoring, controlling, and detection of security threats.
This has been written in the main article to highlight the main issues related to security services for individuals and businesses. The first issue is about the confidentiality of network security. There are some types of direct protection services that ensure that confidential data is not disclosed and that network security is maintained. Encryption is very essential here and in this case a key must be encrypted before it is passed to the receiver. It is very necessary to secure this vital information from unauthorized use or disclosure.
Another aspect is about access control. Access control ensures that only authorized users have access to certain information. An example of access control is the use of password and fingerprint technology to access any computer or data file in the organization. authentication is another aspect of such services and these make the data authentic and hence safe from hacking. Keyless access, proximity card access control, token-based access control are some of the commonly used authentication mechanisms. Data integrity is another aspect of these security services that ensures that no data is lost.

Some of the security services at this website also include data integrity in their mechanism because data integrity ensures the security of the entire system. One can make sure that the entire network is secure by making sure that the communication from the other end is secure. A good example of such mechanisms is VPN (Virtual Private Network). Many of the providers of such security services provide open systems.
There are many other open sources of security services like SSTP (Session Initiation Protocol), IP Sec VPN, L2TP (Internet Protocol), OSP (Open Site Packet Protocol) and MPLS (MLage Transport Layer). All the aforementioned mentioned protocols are based on security properties that guarantee a high level of confidentiality. So if you are looking for high level of security then you should go for open source software and the most recommended one in recent times has been SSTP.
