Data espionage

To effec­tive­ly fight against data espi­onage and inter­cep­tion, SSL/TLS cer­tifi­cates are the solu­tion because they make it impos­si­ble to hack the infor­ma­tion exchanged between the serv­er and the brows­er.

An SSL (Secure Sock­et Lay­er) or TLS (Trans­port Lay­er Secu­ri­ty) cer­tifi­cate is a dig­i­tal cer­tifi­cate that authen­ti­cates a serv­er (most often a web serv­er) and encrypts the data exchanged with it. The data is thus exchanged in con­fi­dence, between two actors whose iden­ti­ty is known. The data exchanged can­not be spied on or altered by a third par­ty: con­fi­den­tial­i­ty and integri­ty.

SSL/TLS cer­tifi­cates allow to switch to HTTPS when brows­ing the Web. They work on the prin­ci­ple of asym­met­ric encryp­tion using cryp­to­graph­ic keys. The SSL/TLS pro­to­col acti­vates a secure ses­sion between a brows­er and the web serv­er that hosts the SSL cer­tifi­cate.

For a brows­er to trust an SSL cer­tifi­cate, it must be issued by a trust­ed third par­ty: the Cer­ti­fi­ca­tion Author­i­ty, fol­low­ing the rules defined by a reg­u­la­to­ry body, the CA/B forum. In addi­tion, the cer­tifi­cate must be cor­rect­ly installed and must con­tain the domain name of the vis­it­ed web­site. With­out these pre­req­ui­sites, the web user receives a secu­ri­ty alert when the page is dis­played, which is pro­hib­i­tive..
