1.1 Define the concept and application of cryptography

Unit DSC01: Cryptography

QUALIFI Level 5 Diploma in Cyber Security

Unit code: J/617/4634 RQF

level: 5


The process of encrypting and decrypting information forms the basis of much computer, device and network security. Cryptography is designed and used to protect the confidentiality, integrity and authenticity of information. From the very beginnings of computing, and throughout the industry’s evolution, the establishment of policies, guidelines and laws has shaped the disciplines of information security and organisational resilience in profound and, often, unintended, ways.

In this unit learners will be introduced to the concept and history of cryptography, and its subdisciplines (including cryptology), and how cyber-enabled networks and devices have their communications security underpinned by cryptographic methods and sector standards. Learners will explore methods of attack, including side-channel, additional encryption methods and escrow principles and key.

Learners will look at how businesses can deploy encryption to enhance their information security approaches.

Learners will develop an understanding of security technical and generic management and leadership teaching. Much of this teaching will be particularly relevant to learners wishing to move into more advanced Information Security Management technical qualifications, including the CompTIA Security + accreditation and the Cyber Security industry gold standard: The Certified Information Systems Security Professional (CISSP).

Assessment Guidance

Each unit will be worth 30 credits and the qualification is designed to be flexible for learners who are already working and in demanding jobs. Every unit must be passed in order to achieve the Diploma.

Learners will be able to progress sequentially through each unit, accumulating credits as they pass each module assessment point.

During each of the four 30-credit units, every learner will have the opportunity to ‘practise’ and hone their ability to undertake the final (formal) assessment. Such non-mandatory practice will by way of completing a formative exercise/s throughout the unit.

Summative Assignment: CONSULTANCY REPORT - Write a company or business report reviewing a) existing encryption arrangements within the IT system, and b) offering a Courses of Action group of recommendations for the company’s CISO (3000 words).
