We have a saying at Splunk. It goes something like “if you’re ever having a bad day, go and talk to a customer”. What organizations around the world are doing with their data and Splunk brings a huge smile and an eyebrow raising, positive “can’t quite believe you’ve done that” very-impressed nod of the head. That’s never more true than with our security customers.
The goal of system hardening (or security hardening) is to reduce the attack surface. It includes reducing security risks and removing potential attack vectors. By removing superfluous programs, accounts functions, applications, ports permissions access etc., the reduced attack surface means the underlying system will be less vulnerable, making it harder for attackers or malware to gain a foothold within your IT ecosystem.
