Security & Compliance

Ensuring that there is no unrestricted inbound access to TCP port 7473 is important in protecting your Neo4j server from unauthorized access and potential attacks. TCP port 7473 is used by Neo4j for secure HTTPS communication with the Neo4j browser, and leaving it open and unrestricted can allow attackers to gain access to sensitive data and execute unauthorized commands on the server. It is essential to ensure that access to this port is limited to authorized users and networks.


To prevent unrestricted inbound access to TCP port 7473, the following remediation steps can be taken:

  • Configure the firewall or security group associated with the server to restrict inbound traffic on TCP port 7473 to authorized IP addresses or networks.
  • Implement SSL/TLS encryption and certificate-based authentication to secure communication with the Neo4j server and prevent unauthorized access.
  • Regularly monitor and audit access logs to detect and respond to any unauthorized access attempts to the server.
