Many people, looking from the view of one operating system or the other, don’t quite get the differences between these two powerhouses. So I decided it might serve the public well to list 10 of
operating system and the resources it is protecting and managing. Each user and each process executed on behalf of that user, is identified by (minimally) two non-negative 16-bit integers:
Chapter 14: Protection 1. What are the main differences between capability lists and access lists? Answer: An access list is a list for each object consisting of the domains with a nonempty set of access rights for that object.
The security differences between the two operating systems can be broken down into simpler concepts by taking out of account the elements that do not …
The protection ring model provides the operating system with various levels at which to execute code or to restrict that code’s access. The rings provide much greater granularity than a system that just operates in user and privileged mode.
The terms protection and security are often used together, and the distinction between them is a bit blurred, but security is generally used in a broad sense to refer to all concerns about controlled access to facilities, while protection describes specific technological mechanisms that support security.
Security policy is just a statement about what is allowed and not allowed to do in a system while security mechanism is a procedure how to implement the security policy.It is said to be a tool,methodology or procedures for security enforcement.
to discover the vulnerabilities of operating system security. For a timeline that includes this For a timeline that includes this and other seminal studies of computer security, see Table 1-1.
Security is a perennial concern for IT administrators. Managers need a framework to evaluate operating system security that includes an assessment of base security, network security and protocols, application security, deployment and operations, assurance, trusted computing, and open standards.

Operating times can vary with fault current, with fault position relative to the relay setting, and with the point on the voltage wave at which the fault occurs.
The difference between protection and security is that protectionis the action of protecting someone or something, or the state ofbeing protected.
The part of the operating system that is responsible controlling access to hardware (including memory management), for protecting processes from one another, and for security functions. Malware Viruses, worms, trojan horses and other software which has evil intent.
Basically the difference between kernel and user modes is not OS dependent and is achieved only by restricting some instructions to be run only in kernel mode by means of hardware design. All other purposes like memory protection can be done only by that restriction.
What is Computer Security? computer hardware and an operating system that supports untrusted applications and users. The seven levels of trust identified by the Criteria range from systems that have minimal protection features to those that provide the highest level of security modern technology can produce (table 1-1). The Criteria attempts to define objective guidelines on which to base

System security : how easy is to break into a system and compromise it, thus having access to the information behind it (access from both inside or outside).
The separation of mechanism and policy is a design principle in computer science. It states that mechanisms (those parts of a system implementation that control the authorization of operations and the allocation of resources ) should not dictate (or overly restrict) the policies according to which decisions are made about which operations to authorize, and which resources to allocate.
operating systems was becoming a significant limitation in these systems. As the initial focus of the Windows operating system was on microcomputer platforms en- visioned for a single user and disconnected from any network, security was not a feature of such

Security Kernel Responsible for implementing the security mechanisms of the entire operating system. Provides the security interfaces among the hardware, the operating system, and the other parts of the computing system. Implementation of a security kernel: May degrade system performance (one more layer). May be large. No guarantees. 9
