Internet TCP port 1521 is commonly used by Oracle Database for client-server communication. This port is the default listening port for Oracle's SQL*Net protocol, which is used in the Oracle Net Services to establish connections to the Oracle Database. Examples of software that use this port include Oracle SQL Developer and Oracle Data Pump. It's crucial to secure this port as it can be a target for attacks aiming to exploit Oracle Database vulnerabilities.
TCP port 1521 is commonly associated with Oracle database services. In the past, hackers have exploited this port to gain unauthorized access to sensitive data. They typically use techniques such as brute force attacks to crack the database's credentials or exploit known vulnerabilities in the Oracle software. Once they gain access, they can manipulate, steal, or delete data. Additionally, they can potentially use this access to move laterally within the network, compromising other systems. Therefore, it's crucial to secure this port with strong credentials and regular software updates.
