What is Port 7199?
Port 7199 is used by Apache Cassandra for JMX (Java Management Extensions) monitoring and management. Operations tools like nodetool use this port to query cluster status, trigger repairs, and manage compaction. Exposed JMX ports are a critical security risk as they can allow remote code execution through MBeans.

Security Considerations
Port 7199 (Cassandra JMX) is classified as critical risk. This port should not be exposed to the public internet. The service transmits data without encryption, making it vulnerable to eavesdropping, credential theft, and man-in-the-middle attacks.
Recommendation: Block this port at the firewall. Use encrypted alternatives (SSH, SFTP, HTTPS) instead.
