How to enable security in presto?

To enable security in Presto, you can follow these steps:

1. Configure Authentication: By default, Presto does not have authentication enabled. To enable authentication for Presto, you need to configure an external authentication method such as LDAP, Kerberos, or OAuth.
2. Configure Authorization: Presto uses an authorization mechanism called "Access Control Lists" (ACLs) to control access to various resources in Presto. You can configure ACLs to restrict access to specific tables, columns, or other resources in Presto.
3. Enable SSL/TLS: To secure the communication between Presto nodes and clients, you can enable SSL/TLS encryption. You need to configure the SSL/TLS settings in the Presto configuration file and generate the necessary SSL/TLS certificates and keys.
4. Monitor and Audit: Enable logging and auditing in Presto to monitor and track user activities and access to resources. You can use tools like Apache Ranger or Presto's built-in audit log to monitor and audit Presto security events.
5. Regularly Update and Patch: Keep your Presto installation up to date by applying security patches and updates. Regularly check for security vulnerabilities and apply necessary fixes to ensure the security of your Presto deployment.

By following these steps, you can enable security in Presto and protect your data and resources from unauthorized access and malicious activities.
