Security vs. Protection

Main Difference

Hospital, in general, have a variety of units based on a specific purpose. Apart from regular rooms and ward admissions, critical patients are either shifted to ICU or a CCU. ICU stands for Intensive Care Unit while CCU stands for Cardiac Care Unit or Coronary Care Unit. Both these terms interrelate in order of their overall occurrence. ICU is a special care unit beside regular room or ward in the hospital, the patients with critical health conditions are kept for high-level care and monitoring. A patient usually after an operation or surgery is kept in the ICU in critical condition. CCU, on the other hand, is a more specific critical care unit beside ICU, regular room and normal hospital ward, that is particularly for the patients suffering from a cardiac disorder. In other words, we can regard a CCU as a special ICU for heart patients only. The major difference between an ICU and CCU is that ICU is mostly for surgical patients whereas a CCU is specifically for heart patients

Difference Between Security and Protection

What is Security?

The security of a system revolves around the outside environment, and in addition, it requires a proper protection system. The security systems incorporate the protection of their computer resources against unauthorized access, malicious alteration, and inconsistency. Here in the special circumstance, the resources are the saved data in the system, CPU, memory, disks, etc..

The security of the system highlights the authentication process of the machine to be able to secure the physical resources in addition to the integrity of the data stored in the system. Security provides a mechanism to safeguard the user’s applications and data contrary to the interference brought on by an entity or individual external to the machine. For instance, in an organization that the data is obtained by different employees but, it can’t be obtained by a user that does not exist in that particular organization or a user working in other business enterprises. It’s the critical task for an organization to supply some safety mechanism so that no outside user can access the information of the organization.

What is Protection?

Protection is a component of safety which controls access to a system by optimizing the kinds of file access allowed to the users. The Protection of a system must ensure the consent of the users or processes. Because of this, these authorized users or processes can operate on the CPU, memory segments, and other sources. The protection mechanism should offer a medium for specifying the controls to be imposed, together with a way of enforcing them.

The Protection was perceived as an addition to a multiprogramming operating system, to stop untrustworthy users from sharing a common physical and logical namespaces, as an instance, a directory of files and memory respectively. Protection is required to intercept the wicked, intentional violation of an access restraint with a user. Though, it’s important to assure that every active program component existing in a system utilizing the system resources only in reliable ways as stated in policies. It includes the avoidance of user’s data and applications against interference by other users of this machine.

The protection can be translated by a similar example as given from the safety, any organization can have several departments under which many employees operate. The various departments can share frequent information with each other but not sensitive information. So, different workers have different access rights to the data according to which they can access the specific data.
