Without strong walls why the gate? Securing data is a big concern for today servers managers, data collecting and storage is crucial, we are living in the beginning of big data era. Some of that data are no for public access, and some information is very confidential, how to deal with that needs a complex answer.
Security access is the basics, it is more than have strong passwords, it is to give right people the right information and keeping not-authorized ones out. As a server admin I can say our servers security is high, but for strictly security performance the server admin words doesn’t guarantee nothing, we need third parties specialists to confirm it.
When a site or domain have SSL certification they have guaranteed that the interception of data between the final user and server is way difficult, all protocols and security norms is followed, and the constat renewal of SSL certificates guarantee the servers is always updated with most recent security standards. That is certainly a big mark for all our projects.
