Elasticsearch data security and the best practice of access control

Elasticsearch data security and the best practice of access control Overview: Elasticsearch is a powerful open source search and analysis engine that can be used to quickly search, analyze and store large amounts of data.However, data security and access control are vital to storage sensitive data or authority control.In this article, we will discuss some best practices to protect Elasticsearch data, and how to use access control to ensure that only authorized users can access and operate data. 1. Enable https: By enabling HTTPS, you can provide a secure communication channel for the Elasticsearch cluster.It uses the SSL/TLS protocol to encrypt and authenticate data to prevent data from being eavesdropped or tampered with during transmission.In the configuration file of Elasticsearch, you can specify the path of the certificate and the private key, as well as other settings related to SSL. Example configuration: # In the ELASTICSEARCH.yml file xpack.security.http.ssl.enabled: true xpack.security.http.ssl.key: /path/to/private.key xpack.security.http.ssl.certificate: /path/to/certificate.crt 2. Use security plug -in: Elasticsearch provides a series of security plug -ins, which can help you enhance the security of data.This includes: -X-Pack Security: This is the official security plug-in provided by Elasticsearch, which provides authentication, authorization, role management and other functions.You can use X-Pack Security to create and manage users, and provide identity verification and authorization for users.In addition, it also provides a fine -grained role permissions setting, which can control the user's access level of indexes, documents and clusters. Example code: # Create a user POST _security/user/john { "password" : "secretpassword", "roles" : [ "admin" ] } # And permissions management POST _security/role/editor { "cluster" : ["monitor"], "indices" : [ { "names" : [ "logs" ], "privileges" : ["read", "write"] } ] } -Search Guard: This is a popular security plug -in, providing many additional security functions, such as fine -grained access control, tracking, auditing, etc.It supports HTTPS, LDAP, Active Directory and other authentication methods, and can be used with X-Pack Security to provide a complete security solution. Example configuration: # Configure Search Guard in Elasticsearch.yml file searchguard.ssl.transport.enabled: true searchguard.ssl.transport.keystore_filepath: /path/to/keystore.jks searchguard.ssl.transport.keystore_password: changeme searchguard.ssl.transport.truststore_filepath: /path/to/truststore.jks searchguard.ssl.transport.truststore_password: changeme 3. Index level access control: By using the document -level index control list (DLS) and field -level index control lists (FLS), data access can be more detailed.DLS allows you to restrict the visibility of certain documents according to the user's role or other conditions, while FLS allows you to limit the fields of returning to the result. Example configuration: # Use DLS and FLS in the query GET /my-index/_search { "query": { "match_all": {} }, "query": { "bool": { "filter": { "terms": { "user_id": [ "john" ] } } } }, "fields": [ "public_field" ] } 4. Prevent remote command execution (RCE): To prevent remote execution command attacks, you should limit the access of the remote console.In the configuration file of Elasticsearch, you can disable remote access by setting the `node.remote_shell_enabled` as` false`. Example configuration: # Disable the remote console in the elasticsearch.yml file node.remote_shell_enabled: false Summarize: It is important to protect the security of Elasticsearch data and ensure that only authorized users can access and operate data.By enabling HTTPS, using security plug -ins, implementing index level access control, and preventing remote command execution, the security of the Elasticsearch cluster can be improved.The above are the best practices of some general -purpose. According to your specific needs and environment, further configuration and measures may also be needed to ensure the security of data.
