Study Notes
Zabbix Encryption Setup and Limitations
- Zabbix encryption setup involves preparing certificates or pre-shared keys, configuring encryption in the frontend, and editing TLS parameters in the proxy or agent configuration file
- TLS Connect specifies the encryption for outgoing connections and can be set to unencrypted, PSK, or certificate
- TLS Accept specifies the encryption for accepting connections and can be set to unencrypted, PSK, or certificate
- Limitations of Zabbix encryption include the need to protect access and key files of a database, plaintext storage of certificate private keys and pre-shared keys, and lack of protection for certain communications
- Encryption increases the time for item checks and actions, does not support network discovery and can lead to rejection of unencrypted connections by passive agents
- Additional Zabbix courses cover advanced encryption setup including encrypting database connections, internal communications, and using external authentication providers
- Practical setup of Zabbix encryption involves creating a directory for encryption keys, generating PSK for Zabbix agent communication, and testing encryption using command line utilities
- Frontend scripts in Zabbix are created in the Administration section and can be used for manual host actions, such as webhooks, scripts, SSH, Telnet, or IPMI commands
- Frontend script parameters include name, scope, menu path, type, execution on, commands, user/host group, and confirmation settings
- Frontend scripts are accessible in the Monitoring section and can be used to execute commands on hosts, where the exit code is checked
- Practical setup of frontend scripts involves creating a "Manual host action" script, giving permissions to Zabbix administrators, limiting script execution to specific host groups, and ensuring the script works
- Zabbix provides practical tasks for users to apply their knowledge of encryption and frontend scripts, with detailed instructions and time allocations for completion
