An introduction to operating system security, which briefly describes the meaning of operating syste

Answer]: The research on the security protection of the operating system usually includes the following contents: First, the security functions and security services provided by the operating system itself.

Modern operating systems often need to provide certain security services in terms of access control, authentication, and authorization. How to study and develop the security performance of the operating system itself to meet the specific environment and needs is one aspect of the security protection of the operating system. secondly, the relevant configuration of the operation shed system for various commonly used rules of negotiation and balance is carried out to make it able to correctly deal with and defend against various intrusions; Third, ensure that the network services provided by the network operating system itself can be securely configured.

It is the cornerstone of computer system security.

Firewalls and the like protect against virus infections and IP address attacks.

Operating System Security is a book published by Beijing University of Posts and Telecommunications Press, and the author is Lin Guoyuan. This book is one of the series of information security textbooks for colleges and universities. The book is divided into 8 chapters, mainly including:

The basic concepts, security mechanisms, security models, security architectures, security design and verification, security evaluations, and security mechanisms and techniques of mainstream operating systems Windows and UNIX Linux are the basic concepts, security mechanisms, security models, security architectures, security design and verification, security evaluations, and security mechanisms and techniques of mainstream operating systems Windows and UNIX Linux.

This book focuses on the combination of the basic theories and concepts of operating system security with the actual operating system security technology, and pays attention to absorbing the latest operating system security research results.

This book can be used as a textbook for undergraduate students majoring in information security, computer science and technology, network engineering, communication engineering, etc., and can also be used as a reference book for undergraduates, graduate students, and teaching and scientific researchers related to information security.

Computer System Security discusses in detail the security requirements, security countermeasures, security models and security system construction theories of computer systems, and systematically introduces the relevant practical issues of security policies and security models in the design of trusted operating systems and the protection of general operating systems. The book introduces and analyzes the common cryptography techniques and cryptographic protocol theories related to computer system security. In addition, from the perspective of computer system confrontation, this book systematically discusses the principles of computer viruses and their prevention, the basic theories of computer virus detection and identification, and the methods and techniques of intrusion detection.
