Answer:
false
Step-by-step explanation:
A root CA (Certificate Authority) should not always be kept online. In fact, it is generally recommended to keep the root CA offline or in an isolated, highly secure environment.
The root CA is responsible for issuing and signing digital certificates that are used to authenticate the identity of entities in a public key infrastructure (PKI). As the highest level of authority in the PKI hierarchy, the root CA's private key must be kept highly secure to prevent unauthorized access and potential compromise.
By keeping the root CA offline, also known as air-gapping, it reduces the risk of the private key being exposed to online threats such as hacking or malware attacks. It adds an extra layer of security by physically isolating the root CA from potential network-based vulnerabilities.
When a digital certificate needs to be issued or revoked, a secure process is followed to temporarily bring the root CA online, perform the necessary tasks, and then return it to the offline state.
Overall, keeping the root CA offline helps to protect the integrity and security of the PKI system.
