Private CA FAQ's
What is a Private Certificate Authority (CA)?
A Private CA is an internal certificate authority used by an organization to issue digital certificates for use within its own network, enhancing security and identity verification.
How does a Private CA differ from a Public CA?
A Private CA issues certificates for internal use within an organization, while a Public CA issues certificates recognized by external users and the internet at large.
Why would an organization use a Private CA?
Organizations use Private CAs to secure internal communications, manage identities, control costs, and ensure that sensitive information remains within the organization’s boundaries.
What are the common use cases for a Private CA?
Common use cases include internal email encryption, server authentication, VPN connections, code signing, and device authentication.
How is a Private CA set up?
Setting up a Private CA involves choosing CA software, configuring the CA server, creating root and intermediate certificates, and establishing policies for certificate issuance.
What are the security considerations for a Private CA?
Security considerations include protecting the CA root key, implementing strong authentication and access controls, regularly auditing certificates, and maintaining up-to-date revocation lists.
Can a Private CA issue certificates for external use?
Typically, a Private CA is not used for external certificates because they are not trusted by external users or systems unless specifically configured.
What software can be used to create a Private CA?
Common software options include Microsoft Active Directory Certificate Services, OpenSSL, EJBCA, and HashiCorp Vault.
What are certificate revocation lists (CRLs), and how are they used in a Private CA?
CRLs are lists of certificates that have been revoked before their expiration date. They are used to ensure that invalid certificates are not trusted by clients.
What are the challenges of managing a Private CA?
Challenges include maintaining key security, managing certificate lifecycle, ensuring compliance with security policies, and scaling the CA infrastructure.
