Security

Thus securing a system involves following measures :

1. Preventing unauthorized access i.e. hiding the information from unauthorisation users.

2. Protection the system from malicious damage or misuse. Such intential misuse can be of the following kinds :

· Theft of information

· Unauthorized modification of data

· Unauthorized destruction of data

3. Protection the system against accidental misuse.

4. The term security is often associated with protection with however, there is a difference between them. Protection is defined as guarding the user information against user within the system whereas security is defined as guarding the user information against unauthorized user outside the system

Micro kernel architecture

Micro kernel architecture What is Kernel? A kernel is an important part of an OS that manages system resources. It also acts as a bridge between the software and hardware of the computer. It is one of the first program which is loaded on start-up after the bootloader. The Kernel is also responsible for offering secure access to the machine's hardware for various programs. It also decides when and how long a certain application uses specific hardware. What is Microkernel? Microkernel is a software or code which contains the required minimum amount of functions, data, and features to implement an operating system. It provides a minimal number of mechanisms, which is good enough to run the most basic functions of an operating system. It allows other parts of the operating system to be implemented as it does not impose a lot of policies. Microkernels and their user environments are usually implemented in the C++ or C programming languages with a little bit of assembly. Ho...

Batch Processing Operating System

Batch processing system · Batch processing is one of the oldest method of running the programs · The computer in the past were very large in size and their I/O devices were very different from those that are used today. The job processing was not interactive as it is today. · The user did not interact directly with computer system. · The process scheduling , memory management, file management and I/Omanagement functions are quite simple in batch processing system 1. Process scheduling (i.e. allocation strategy for a processor is typically in order of their arrival i.e. first come first served(FCFS)basis. 2. Memory management is done by divi...

Time Sharing System and its Requirements

Time sharing system · Time sharing refers to the allocation of computer resources in a time dependent fashion to several program simultaneously · A time sharing system has many user terminals that are connected to same computer simultaneously. Using these terminal, different users can work on a system at the same time · Thus, it uses multi programming with a special CPU scheduling among all the last one, and then again beginning from the first one · In time sharing system, the CPU time is divided among all the users on schedule basis. · It release the CPU under any of the following three conditions: 1. When the allotted time slice expires. 2. ...

OS its Resource Manager and its Function

Operating system as resource manager: · A computer system usually has many hardware and software resources such as processor , memory, disk printer, I/O devices etc. · The task of resources management becomes essential in multi-user operating system where different user compute for the same resource. Operating system manages resources in two ways : 1. Time multiplexing : it defines the sharing of resources on the basis of fixed time slices. For example, the operating system allocate the resources, such as CPUto program A for fixed time slice. 2. Space timing: it defines the concurrent sharing of resources among different programs.for example, sharing of hard disk and main memory is space multiplexing. FUNCTION OF OPERATING SYSTEM The primar...

Protection and security

Protection and security Protection in computer system · In the system with contiguous memory allocation, protection is usually accomplished by the use of limit registers. Each program is assigned a specific limit in term of address space . whenever any reference is made to an instruction of the limit register is checked to ensure that reference is within the bound of program otherwise the access to memory is denied. · In paging system, protection is achieved by the use of a page table. This page table list all the pages that a program can access. · In addition the table store access rights such as read, write or execute for each individual page. · In a system that uses segmentation, protection is accomplished by the use of segment ...
