Unit outline for Security and Privacy (CITS3231).

6 points / Semester 2
Location: UWA (Crawley)

Handbook description

This unit provides an introduction to security in the context of computer systems and the networks that connect them. It commences by examining the representation and support of users in traditional operating systems, how they are authenticated, and how their privileges and resources are stored and manipulated during normal execution of their processes. The approaches to securing an operating system's files are discussed, followed by techniques on securely logging an operating system's activities and ensuring file-system integrity. It also considers the general design of the TCP/IP protocol suite, the impact of the lack of a fundamental security model, an explanation of some common vulnerabilities in its protocols, contemporary thinking on, and solutions to these. The basic building blocks of cryptography are discussed, followed by examples of how and where these techniques are often employed in secure Internet protocols, applications and within the World Wide Web. The unit concludes with an examination of robust programming techniques.

Prerequisites: CITS2230 Operating Systems or CITS3230 Computer Networks

Unit aims

Students have a sound understanding of the importance of confidentiality, authentication and privacy in the use of computer and network systems, and the roles of cryptographic techniques, standard protocols and specifications for security; appreciate the professional and ethical responsibilities they hold in securing information in computer and network systems; and are aware of the government's role and impact in a global and societal context. The unit provides students with an opportunity to undertake problem identification, analysis and solution and to apply these skills to the discipline. The unit provides the foundation for further development of in-depth competence in this field.

Assessment

This comprises a programming project, a mid-semester test and a final examination. The programming project develops the ability to undertake problem identification, formulation and solution, the ability to apply fundamental knowledge and in-depth technical competence. The programming project is undertaken in small teams and requires the programming work to be clearly documented. It develops and enhances teamwork and communication skills. The written test and examination also require students to undertake problem identification, formulation and solution by requiring short answers to problems drawing on both related and contrasting issues presented in the unit. Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete the course.

Unsatisfactory progress

Any student who does not demonstrate satisfactory progress in this unit, as defined in the Faculty's policies on assessment practices and procedures, may be refused admission to the final examinations. The final deadline for notification of unsatisfactory progress is the last day of Week 10.

Penalties

The School of Computer Science and Software Engineering has adopted a policy on minimum penalties for late items of assessment. This is the default policy of all units unless indicated otherwise, in writing, by the specific unit coordinator.

This policy shall apply to all items of continuous assessment, whether submitted either physically or electronically. Immediately after the submission deadline for an item of continuous assessment, a penalty of 20 percent will be applied PER DAY or PART THEREOF. The minimum mark possible for late submission is zero. The percentage is based on the item´s total contribution to the unit´s assessment. For example, a project contributing 40% to the unit´s assessment will incur a penalty of 8 marks for each day late until it is submitted or a mark of zero results.

A more detailed description is given in this School´s policy on late submission. The Faculty does have an appeals procedure, the details of which can found at the policy for appeals.

Special consideration

Applications for consideration, deferral of tests or exams or extensions of time for assignments on medical, personal or other grounds must be lodged with the faculty office no later than three working days after the due date for the assessment in question. This rule will apply to all students, except in exceptional circumstances.

Plagiarism

Plagiarism is broadly defined to be when any portion of the work presented for assessment, can be attributed to another party. The student making the submission should acknowledge what aspects of the presented work is not directly derived by them. For the purposes of plagiarism it is irrelevant that you have been given permission by someone to copy their work and present it as your own.

You are directed to the Faculty's policy on plagiarism.

Academic misconduct

The University of Western Australia strongly supports teaching and learning that promotes academic literacy and ethical scholarship for all students. As part of this commitment, UWA has recently developed new guidelines relating to Academic Misconduct (including plagiarism). It is also developing a range of resources for students and staff to further strengthen academic literacy and ethical scholarship at UWA. Further information is available on the Teaching and Learning website.

Academic Conduct Essentials (ACE)

All students who have not previously been enrolled at UWA are required to complete a short compulsory online module called Academic Conduct Essentials (ACE) within the first 10 weeks of semester. ACE introduces students to essential knowledge regarding ethical scholarship, helps prepare them for the expectations of their university career and informs them of correct academic conduct.

The unit can be accessed via WebCT. The final unit quiz must be completed with a mark of 80% or greater. Students may attempt the quiz as many times as they wish to gain the required pass mark. Completion of the unit will be recorded as an Ungraded Pass (UP) on students’ academic records. Non-completion (NC) within the required timeframe will also be documented on formal academic records.

Faculty Marks Adjustment Policy

Final assessment is subject to the Faculty's scaling policy.

Supplementary Examinations

Supplementary examinations will be awarded in accordance with the Faculty policy on supplementary assessment.
