Seminar Topic: Security in Operating System

Introduction:

Protection is an internal problem.Security must consider both the computer system and the enviroment(people,buildings,valuable objects and threats) within which the system is used. It is easier to protect against accidental loss of data consistency than to protect against malicious access to the data.Absolute protection of the information stored in the computer system from malicious abuse is not possible. The various authorization provisions in a computer system may not confer sufficient protection for highly sensitive data.In such cases,data may be encrypted. It is not possible for encrypted data to be read unless the reader knows how to decrypt the encrypted data.
