System/application attacks fall within three categories: denial or destruction, alteration, and disclosure. This paper will cover some common system/application domain vulnerabilities: unauthorized physical and logical access to resources, weaknesses in server operating system and application software, and data loss.

12. Type the next command "id" and you should get a string in return similar to this "‘uid=(0)root gid=(0)root’. Repeat the steps with the commands again if you don't see that string or else you risk soft-bricking the

Formal user access control procedures must be documented, implemented and kept up to date for each application and information system to ensure authorised user access and to prevent unauthorised access. They must cover all stages of the lifecycle of user access, from the initial registration of new users to the final de-registration of users who no longer require access. These must be agreed by IDI. User access rights must be reviewed at regular intervals to ensure that the appropriate rights are still allocated. System administration accounts must only be provided to users that are required to perform system administration tasks.

During the reconnaissance step of the attack, describe what task Zenmap GUI performs to do passive OS fingerprinting.

As basic users, security is one feature that most of us overlook when it comes to operating systems until it is too late. In this paper we will discuss the security flaws within the Windows Operating system, and then discuss countermeasures to fix the system flaw.

1. The relative advantages and disadvantages of at least three different measures used to protect operating systems.

One form of hardware support that guarantees that a buffer overflow attack does not take place is to prevent the execution of code that is located in the stack segment of a process’s address space.

Depending on your personal preference and need, there are a variety of operating systems available to users today. Whether it’s MAC OS, UNIX, Windows, etc they each have their own aspects and appeal that draw users in. The spotlight however, for the duration of this paper will be placed on a derivative of the UNIX family of operating system, Linux. The topics covered will include the history to include a handful of versions (distributions).

Three operating systems discuss in this paper each have their advantages and disadvantages from one another. The biggest advantage for Microsoft is the widespread use and compatibility with most every type of program out there. If you 're a Linux fan then you appreciate not only the price which is usually free but also that it is

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

"W⊕X" protection is a memory protection policy. It states that a memory location can be mark as writable or executable, but never both. This protection prevents attackers from injecting malicious code to take control over a process. The injected code is considered as data in memory. Diverting the control flow to execute memory location marked as writable will result in a processor exception. Stack-smashing attacks are prevented as there is no location in memory available for attacker to inject and execute shell code.

Terminal should be constructed in such a way that data which is under control of acquirer is only initialised and updated by the acquirer (or its agent).

It is used to manipulate the process such as to change the priority of a process, or to kill a process
