The course provides a study of the principles and practice of security for both stored and transmitted information. It addresses the fundamental principles of computer and network security and covers: Internet Threats and Hacker Techniques, Firewall Security, Intrusion Detection Systems, Authentication, Encryption Technologies, Public Key Management, Virtual Private Networks and Wireless Network Security.

• Cryptography: symmetric and asymmetric cryptographic protocols, key distribution, authentication and digital signatures.
• Network security: access control, services and mechanisms for authentication, network security protocols, application layer security and secure network management.

Learning Outcomes

To get a basic understanding of principles and practice of cryptography and network security by gaining knowledge in:
1) cryptographic algorithms;
2) techniques and algorithms for key management, key distribution and user authentication;
3) use of cryptographic algorithms in network protocols and network applications.
4) techniques for securing computers against intruders and malicious softwares.

To develop the ability:
1) To evaluate security of systems with respect to appropriate use of security services and mechanisms;
2) To design basic security architectures through selection and integration of relevant security components.

Additional material (e.g. Youtube videos), lecture slides and labs sheets will be published on Learn as the course progresses.


There are several important documents available online about departmental regulations, policies and guidelines at the following site. We expect all students to be familiar with these.

Notices about this class will be posted to the class forum in the Learn system.

COSC students will also be made members of a class called “CSSE Notices”, where general notices will be posted that apply to all classes (such as information about building access or job opportunities).

Additional Course Outline Information

Grade moderation

The Computer Science department's grading policy states that in order to pass a course you must meet two requirements:
1. You must achieve an average grade of at least 50% over all assessment items.
2. You must achieve an average mark of at least 45% on invigilated assessment items.
If you satisfy both these criteria, your grade will be determined by the following University- wide scale for converting marks to grades: an average mark of 50% is sufficient for a C- grade, an average mark of 55% earns a C grade, 60% earns a B- grade and so forth. However if you do not satisfy both the passing criteria you will be given either a D or E grade depending on marks. Marks are sometimes scaled to achieve consistency between courses from year to year.

Students may apply for special consideration if their performance in an assessment is affected by extenuating circumstances beyond their control.

Applications for special consideration should be submitted via the Examinations Office website within five days of the assessment.

Where an extension may be granted for an assessment, this will be decided by direct application to the Department and an application to the Examinations Office may not be required.

Special consideration is not available for items worth less than 10% of the course.

Students prevented by extenuating circumstances from completing the course after the final date for withdrawing, may apply for special consideration for late discontinuation of the course. Applications must be submitted to the Examinations Office within five days of the end of the main examination period for the semester.
