The text discusses the security challenges associated with Elasticsearch databases, highlighting several high-profile data breaches involving companies like Avon and Family Tree. Bob Diachenko, a cybersecurity researcher, notes that a significant proportion of NoSQL data breaches involve Elasticsearch due to common mistakes such as failing to secure default configurations, not implementing authentication, and storing data as plain text. The article emphasizes the importance of addressing these issues by implementing security features early in the development process, which Elasticsearch has attempted to facilitate by including security measures like TLS encryption and role-based access control in its free tier. Additionally, the text discusses the dangers of exposing Elasticsearch databases to the internet and the risks of inadequate script security, recommending best practices such as salting and hashing passwords and using secure scripting languages like Painless. Ultimately, while Elasticsearch has made strides to improve security, the responsibility for maintaining database security lies with developers.
