Ensure that Microsoft Azure network security groups (NSGs) do not allow unrestricted access on TCP ports 27017, 27018 or 27019 in order to protect against attackers that use brute force methods to gain access to Azure virtual machines associated with these NSGs. MongoDB Database is a free and open-source cross-platform document-oriented NoSQL database.
This rule resolution is part of the Conformity Security & Compliance tool for Azure.
Allowing unrestricted access to your Azure virtual machines (VMs) via network security groups (NSGs) can increase opportunities for malicious activities such as hacking, denial-of-service (DoS) attacks and loss of data.
