For secure online business, as well as to maintain complete confidentiality critical information you need to take care of providing decent security for the site. Industry standard in this area is SSL.
SSL abbreviation stands for Secure Socket Layer, which in the literal translation of the Russian language means "Secure Sockets Layer". The tasks include the implementation of SSL high security compounds. For the implementation of the SSL protocol is used SSL-certificate, clearly describing the server and accesses to it users.
SSL certificate proves the authenticity of the actual uses of his company and the absolute security of data transmission in which information can be neither intercepted nor modified. Thus, the audience of the site will be guaranteed the best defense of the operations that positively affects the level of confidence.
Scope of SSL Certificates is quite varied:
• Safety making financial transactions.
• Protection of valuable user data.
• High degree of confidentiality of information transmitted via email.
SSL certificates are divided into different types of properties such as:
1. The degree of confidence.
1.1. Confidence - Trusted. This is a SSL-certificates issued by certification authorities directly. Because these centers are disinterested party in the process of communication, they seem official guarantors of security of the connection. Such an SSL-certificate is a set of public and private key (this text file) that is related to a specific domain name. The first of these is open to all users, while the second is available only for the resource owner.
1.2. Untrusted - Self-Signed. This is a manually created certificates, which can only confirm their owner. And in fact, the security Providers are not advocates of any one person that you could on all the grounds to request the report in case of break-certificate.
2. The number of protected domains.
2.1. Standard - Standard. These SSL certificates organize security for only one domain.
2.2. Group - WildCard. Here all the conditions for protection as the main domain and all subdomains.
3. The owner of an SSL certificate.
3.1. Individual - Private. Defined for a single owner and single domain name.
3.2. Common - Shared. These SSL certificates are used to simultaneously protect the right of a number of sites, respectively, they are guided by the same key, which reduces considerably the degree of protection.
The principle of SSL certificates is based on two concepts:
Authentication - checking domain in full conformity with the address from which the user is connected.
Encryption - special coding of information transmitted between the server and user.
That particular site is protected by SSL certificate shows a closed padlock image that is in the far right of the address bar, and an indication of the https protocol next to the domain name.
SSL Certificate displays complete information about the company's owner, its territorial affiliation, address and clearly the duration of this certificate.
To ensure the highest degree of reliability data and store it in its original form such protective measure is optimal.
