What are the principles of protection?
The principle of protection involves placing a barrier between the pathogen and the susceptible part of the host to shield the host from the pathogen. This can be accomplished by regulation of the environment, cultural and handling practices, control of insect carriers, and application of chemical…
What is the role of protection in computer systems?
To improve reliability by detecting latent error s. The role of protection is to provide a mechanism that implement policies which defines the uses of resources in the computer system. Some policies are defined at the time of design of the system, some are designed by management of the system and some are defined by the users ...
What is system protection?
Protection refers to a mechanism which controls the access of programs, processes, or users to the resources defined by a computer system.
Why should application programmer design the protection mechanism?
Application programmer should also design the protection mechanism to protect their system against misuse. Policy is different from mechanism. Mechanisms determine how something will be done and policies determine what will be done.Policies are changed over time and place to place.
What is the need to know principles?
The need to know principlestates that a process should only have access to those objects it needs to accomplish its task, and furthermore only in the modes for which it needs access and only during the time frame when it needs access. The modes available for a particular object may depend upon its type.
Is kernel based protection stronger?
Where hardware support of individual memory accesses is available, the protection is stronger still. Flexibility. A kernel-based protection system is not as flexible to provide the specific protection needed by an individual programmer, though it may provide support which the programmer may make use of.
Why do we need protection?
To ensure data safety, process and program safety against illegal user access, or even program access, we need protection. It is to ensure that programs, resources and data are accessed only according to the systems’ policies.
What is protection policy?
For that purpose, we have protection policies that are either designed by the system itself or specified by the management itself or are imposed by the programmers individually to protect their programs with extra safety.
How does cryptography protect data?
This helps in transfer of data with full protection. It protects the data by introducing the concept of a key. The key is very important here.
What is the protected domain of a process?
That is the protected domain of a process. A computer system has processes and objects, which are treated as abstract data types, and these objects have operations specific to them. A domain element is described as <object, {set of operations on object}>. Each domain consists of a set of objects and the operations that can be performed on them.
What is the domain of protection?
Domain of Protection : The protection policies limit the access of each process with respect to their resource handling. A process is bound to use only those resources which it requires to complete its task, in the time limit that it requires and also the mode in which it is required. That is the protected domain of a process.
