Data protection is becoming increasingly relevant as information technology develops and spreads. An important role in this matter is played by the SSL certificate for the site. For what purpose is it created? How to install / connect a certificate? Is it possible to check its performance?
general information
First, let's figure out what SSL is. Its name translates as “secure socket level”. It is used to protect data transmitted on the Internet by millions of sites. By using this protocol, a high level of security is ensured between the server and the user. Its use provides for the transfer of all data over the HTTPS channel, while decryption can only be carried out using a special key. In favor of the high reliability of this protocol is the fact that it is used by all financial institutions. Of great importance in this scheme is the SSL certificate for the site. What is he like?SSL certificate
For a site, it is a kind of unique digital signature. It is necessary for all banks, payment systems and other organizations that work with personal data. Thanks to it, transactions are protected and unauthorized access to information is prevented. It may contain the following information:
- The domain name for which the certificate is created.
- The legal entity owning it.
- The physical location of the subject for which the certificate is being created.
- Validity.
- Details of the company that formed the certificate.
This file is used to confirm the results of identification of the owner and the legality of the actions taken. This is why you need an SSL certificate for the site.

In this case, the issuance of certificates is implied only after verification of the company. This option is suitable for those who want visitors to have confidence in their products, services and companies. In such cases, certification authorities perform a thorough review. It is necessary to send the required package of documents and wait for the call to the corporate phone. When installing an SSL certificate on an extended site, security address is displayed in green in the address bar. This is exactly what we find on the pages of banks and payment systems. Often, additional subdomain support is also offered. This is a good option in case of significant branching of the site structure.How can I find out that staying on the site is safe?

How to install an SSL certificate on a website on a global network? To do this, you need to contact a company that specializes in this. If we talk about paid certificates, then their value can reach up to five thousand rubles per year. But there is an opportunity to ensure the security of your data for free. True, one does not have to rely on the level of banks. To obtain a certificate after choosing a company, you need to decide at what rate the service will be provided. If safety is simply ensured, then this is one amount. And if there is a desire to still tell customers in green that they can not worry, this is completely different.Why are website owners increasingly using SSL?
E-commerce is growing rapidly. And in the global network, the security issue is paramount. Many people are repelled by the need to transfer personal data to someone else. After all, I so want to have a guarantee that all the information provided will be kept secret. If a potential customer does not have such confidence, he is unlikely to buy something. And the presence of SSL allows us to say that the organization respects this, and it will make sure that the data does not fall into the wrong hands. Of course, the mere presence of a certificate does not give full confidence. Indeed, for completeness, it is still necessary to ensure the security of internal channels in the organization, its units and the reliability of employees. But the certificate says at least that these issues are not an empty phrase.How does it all work?

Conclusion
Why is there a need for all these certificates? Alas, the reason for this is sad - a large number of scammers on the network. Counterfeiting sites, trying to get money from inattentive and gullible people - all this requires the adoption of certain measures aimed at ensuring security. To have an idea of the total expression of offenses that are being carried out in this area, it is enough to give a small example: cases of fraud that are recorded bring hundreds of billions of US dollars of losses a year!
