TLS/SSL and Network Security
Secure communication within your cluster and with clients using Transport Layer Security (TLS/SSL) and other network security best practices.
Securing Data in Transit
When data travels across a network, it's vulnerable to interception. TLS (Transport Layer Security) and its predecessor SSL (Secure Sockets Layer) are cryptographic protocols designed to secure this communication.
They create an encrypted link between a client and a server, ensuring that data remains private and untampered with during transit.
Why TLS/SSL for Elasticsearch?
Elasticsearch often handles sensitive data. Securing it with TLS/SSL is crucial for several reasons:
- Data Privacy: Prevents unauthorized parties from reading your data.
- Data Integrity: Ensures data isn't altered during transmission.
- Authentication: Verifies the identity of clients and servers.
- Compliance: Many regulations (e.g., GDPR, HIPAA) mandate data encryption.
