There is a certain set of basic security principles that should be followed in an organization, which, in turn, will lead to an effective security posture that will eventually protect against security-related attacks. We have divided them into three major sections, as follows:
- Only run the necessary services: This is one of the important aspects to follow. Only run services that are necessary and remove all the unnecessary services from the system. We also need to make sure that the services running do not have any security vulnerabilities associated with them.
- Separate server by function: This is a mandatory requirement for PCI DSS. It mandates that each server should serve a single purpose. If you have a single large server to manage your workload and if it gets compromised, then all services within this server will be compromised...
