TCP — Database
Ikhtisar Port
Apa itu Port 9042?
Port 9042 is the native CQL (Cassandra Query Language) port for Apache Cassandra, used by all modern Cassandra drivers and client applications. The CQL binary protocol replaced the legacy Thrift protocol and provides a more efficient and feature-rich interface for database operations. This is the primary port that applications use to communicate with Cassandra clusters.
Pertimbangan Keamanan
Port 9042 (Cassandra CQL Native) diklasifikasikan sebagai risiko kritis. Port ini tidak boleh diekspos ke internet publik. Layanan ini mentransmisikan data tanpa enkripsi, sehingga rentan terhadap penyadapan, pencurian kredensial, dan serangan man-in-the-middle.
Rekomendasi: Blokir port ini di firewall. Gunakan alternatif terenkripsi (SSH, SFTP, HTTPS) sebagai gantinya.
