Diploma in Cybersecurity | Dublin Business School  


Cybersecurity is the protection of internet-connected systems such as networks, devices, programs, and data from cyber-attacks or unauthorised access. The World Economic Forum lists cyber-attacks as 5th in the top 10 global risks and this can affect an individual’s business or work in a number of ways. Cybersecurity is therefore used by individuals and businesses to protect against unauthorised access to data centres and computerised systems. DBS cybersecurity courses are part of a new suite of professional diplomas and courses that provide students the opportunity to upskill and enhance skills for the work environment.

Our Professional Diploma in Cybersecurity looks at the four main areas of security: Web, Systems, Communications and Software: Secure Web; Secure Systems; Secure Communications; Secure Software. Learners will understand the fundamentals of cybersecurity with hands-on practical experience of key areas. This programme is specifically designed to give learners the knowledge and skills to implement changes that have tangible benefit to their respective companies and also give them the confidence required to communicate the importance of cybersecurity within an organisation to non-technical people. This cybersecurity programme has been designed for learners with non-cognate backgrounds and no technical knowledge or those with cognate background but lacking technical skills and knowledge.

DBS is an active member of the national cybersecurity cluster, Cyber Ireland, which has over 130 members invested into the cybersecurity ecosystem, including UCD, McAfee, Accenture, IBM, Hewlett Packard and Ergo. As a member, the College has been provided with regular access to a number of events, research materials and industry liaisons informing the College in the development of this programme as well as cybersecurity modules on existing taught programmes. If you want to further your education even more in the cybersecurity field, DBS offer a Master of Science in Cybersecurity

Programme Aims and Objectives


Aims of Cybersecurity Course
This programme aims to immerse learners into the area of Cybersecurity with a view to enabling them to be able to act on the real threats that face companies in today’s business environment.


  • Provide learners with an understanding of the threats posed to websites including session hijacking, secure authentication and SQL injection attacks.

  • Equip learners to do full penetration testing on their systems.

  • Introduce learners to the area of cryptography by using public-key (asymmetric) encryption to do secure communication.

  • Understand the risks posed by unsecure software, looking at some of the threats posed by common vulnerabilities including buffer overflow, heap overflow and stack overflow.

To successfully complete the programme the learners will be assessed through 3 separate individual assessments. These practical assessments will enable the students to apply the topics covered as part of the programme.

  •  Please note this programme is not on the National Framework of Qualifications (NFQ).

Course Content

The lecturing team consists of a team of staff that combine both academic qualifications with substantial practical experience, and this practical perspective is reflected in the delivery of the course. The diploma is broken into 4 areas: secure web, secure communications, secure systems and secure software. Some of the key subject areas are the following:

Secure Web

Websites are a vital part of business in today’s world. They are also a major threat factor when securing your business. As part of this topic, we will look at the various threats that exist including session hijacking, secure authentication using JSON Web Tokens (JWT), HTTPS over HTTP and SQL Injection attacks.

Secure Systems

A company’s website and email server are not the only entry point to their systems. It is not uncommon for companies to leave open ports, either intentionally when using third party services or unintentionally when installing or configuring new software. Penetration Testing is the practice of testing a computer system, network or web application to find security vulnerabilities that an attacker could exploit. Here will examine all of steps involved in the process: Planning and reconnaissance, Scanning, Gaining, Access, Maintaining access and Analysis.

In addition, we will simulate how MAC Flooding with ARP Spoofing attack works and how to protect against it.

Secure Communications

A company email format is rarely secret. Their domain addresses are normally listed on their website. This leads various attempts to access systems using email phishing techniques. We will look at how email phishing works and how to protect against it.

This section will also look asymmetric (public-key) cryptography and how it can be used in secure communications.

Secure Software

Many businesses today rely on custom built software that will be installed internally on their systems. Using third party software to scan for potential threats is one part of the process, but here we dig a little deeper to look at some common software vulnerabilities including: buffer overflow, heap overflow and stack overflow.
