Server security hardening
Server hardening is a necessary process since hackers can gain access through unsecured ports. Hence, to limit the entry points, we block the unused ports and protocols as well as disable the services which are not required. All of this process reduces the attack surface area and eliminates a large number of tactics an attacker could utilize.
Another benefit talks about streamlining done by the server hardware which can help to prevent crashes due to overloads or overconsumption of resources. Although new systems are much more powerful, doing too much on the device could lead to its failure as well.
