Description

The course covers principles and practice of cryptography and network security. The first half of the course focuses on cryptography (symmetric and public-key cryptographic protocols, key distribution, authentication, digital signature schemes). The second half focuses on network security (access control services and mechanisms for authentication, network security protocols, application layer security and secure network management).

In this course, you will learn about fundamental concepts of cryptography, network security, software security, and system security. You will also explore threats and vulnerabilities in the context of how systems can be compromised and how we can prevent harm to systems.

Core topics include:
• Fundamental concepts of cryptography, including symmetric encryption, public-key encryption, cryptographic hash functions, digital certificates, and public key infrastructure
• Selected network security protocols
• Common attack frameworks and cyber attacks, including denial-of-service (DoS) attacks and malware attacks  
• Common cyber defences, including authentication, access control, firewalls, and intrusion detection and prevention systems.
• Software weaknesses and vulnerability assessment  
• Operating system security
• IT security management and risk assessment

Learning Outcomes

  • Students who achieve a good grade in the course should be able to:
  • identify and describe cryptographic algorithms, compare their use and the issues of strength.
  • describe computer security technology and principles such as authentication, denial of services, intrusion detection, and firewalls
  • describe security threats and their countermeasures in software, computer systems, networks
  • describe security protocols and standards used to provide security for communications across the Internet
  • apply the security fundamentals to management aspects of information and computer security.
  • develop the ability to compare and criticize computer security techniques
  • develop appraise of current and emerging computer and network security technologies

Textbooks / Resources

Required Texts

William Stallings & Lawrie Brown; Computer Security: Principles and Practice ; 3; Prentice Hall, 2015.

• Other books will be used in the course if necessary.
• Material (e.g., PowerPoint slides) from the course reader and lecture slides will be published on Learn as the course progresses.

Notes

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 C+ 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.
