Computer security is a specialized area of computer science that studies threats to computer systems and networks, and develops the science and practice of how to mitigate them. As much of our lives today take place on the internet, we depend on safe threat-free computers. Computer Security specialists help improve security for online interactions and protect our data from virus attacks. 

What You'll Learn 

In our Computer Security program you will build a solid background in computer science and math. You will study a variety of courses, including cryptography and operating systems. Computer security is the specialized part of computer science that studies threats to computer systems and networks. It is the science and practise of how to mitigate them. You will become an expert on all those topics.

After third year, you can put your knowledge to the test by taking part in our paid internship program. We have teamed up with a variety of major companies to ensure you get some valuable professional experience.

We offer both BA and BSc degrees, which share the same computer science and math requirements. In the BA program, you will complement your studies with courses from the Liberal Arts (e.g., humanities, social sciences). In BSc, the complimentary courses will be in the sciences (e.g., biology, chemistry, physics).

Some Courses You'll Take 

  • Design and Analysis of Algorithms
  • Communication Networks
  • Operating System Design
  • Computer Security Management
  • Computer Security Lab
  • Introduction to Database Systems
  • Applied Cryptography
  • Computer Security Management and Forensics

Career Paths Include 

  • Computer Forensics
  • Security and Privacy Law
  • Security Risk Assessment
  • Penetration Testing

What is the difference between Computer Science, Computer Security, Computer Engineering and Information Technology?

Computer Science deals with the theory and practice of computer hardware and software. Students learn the theory that underlies computation and how to develop effective, efficient and correct software. The program is intensive in Mathematics and Computer Science courses.

Computer Security focuses on the privacy of personal data, preventing unauthorized access to computer systems, ensuring back-up contingency plans in the event of data loss and protecting systems from malicious activity.

Computer Engineering looks at how fundamental engineering design principles can be used to develop computer software and hardware while teaching you how to keep your knowledge and skills current as technology advances.

Information Technology deals with the application of technology to the organization. The program deals with how technology can be applied, rather than the technology itself.

Internationalize your degree

The iBA and iBSc degree programs reflect York's commitment to internationalization and requires you to acquire an international language and to gain international experience on exchange at one of York University's partner institutions abroad. You will benefit from enhanced interdisciplinary and cross-cultural knowledge, which are important components of the department's academic focus. Visit the International program page for more information.

You are required to provide official evidence of academic achievement in secondary education. This can be demonstrated through:

  • Final grades under the Ontario curriculum (obtained through correspondence, night school or through TVO)
  • Credentials through other curricula, such as results from Advanced Placement (AP) or Advanced-level courses in the General Certificate of Education (Gene). (Students may register to sit for the AP and GCE examinations as private candidates.)

In the absence of final grades in courses:

  • You must submit the results of standardized tests such as the Scholastic Aptitude Test (SAT) with a minimum of 550 (Reading) and 550 (Math) or a composite American College Testing (ACT) score of 24.
  • Your application will be reviewed by an admissions sub-committee. If admitted, you will not be eligible for entrance scholarships. You will be considered for continuing student scholarships at the end of your first year of study, if you satisfy those criteria.
You may also be required to provide proof of language proficiency. You will be considered for entrance scholarships on the basis of your overall averages in the six 4U/4M (Ontario curriculum) or equivalent courses.
