>> Securing Couchbase Server using Let’s Encrypt x.509 Certificates
>> Securing data and access to data for application data is an important step in securing
your environment for client applications and database protection in any sized environment.
One of the simplest methods to secure data is the access path from application to database
server. Some databases employ closed schemes for securing client communications for session
connections to the database but Couchbase server employs TLS certificates for securing communications.
This process can be complex to the uninitiated but Let’s Encrypt, a new, free, certificate
authority is aiming to change that and bring security technology to everyone.
