The blog post by Jared Carey outlines the process of implementing Transport Layer Security (TLS) across the Elastic Stack, which includes Elasticsearch, Kibana, Beats, and Logstash, to ensure secure data transmission. The guide highlights the importance of TLS in protecting sensitive data from potential cybersecurity threats, such as compromised routers that can expose unencrypted data. It provides detailed instructions on setting up TLS, including generating certificates using the certgen tool provided by the X-Pack plugin, configuring Elasticsearch nodes, and setting up Kibana, Logstash, and Filebeat for encrypted communications. The post emphasizes the need for a certificate authority to sign certificates and explains the process of creating server certificates with specific DNS names to ensure proper identity verification. Additionally, it discusses the setup of roles and users within Kibana to secure the logging system further. While the instructions reference deprecated features, the article serves as a comprehensive guide for implementing TLS encryption in the Elastic Stack to enhance cybersecurity measures.
