What Is the Role of a Certificate Authority in Digital Security?
The role of a Certificate Authority (CA) in digital security is to issue digital certificates that authenticate the identity of entities and enable secure data encryption over the internet.
How Do Certificate Authorities Validate the Identity of Entities?
Certificate Authorities validate the identity of entities through various levels of vetting, including domain validation for basic verification, and more stringent checks like organization validation and extended validation for higher security.
What Happens If a Certificate Authority Is Compromised?
If a Certificate Authority is compromised, attackers can issue fraudulent certificates, leading to potential man-in-the-middle attacks and a breakdown of trust in secure communications.
Why Are Root Certificates Important in the Context of Certificate Authorities?
Root certificates are important because they are at the top of the certificate chain; a trusted root ensures that all subsequently issued certificates are also trusted, forming the basis of secure internet communications.
