Assessment Details:
Any IT graduate involved in network security will need to be able to adapt and respond to unfamiliar and changing security threats, technologies and systems. To be capable in their profession, graduates need to be able to discover and analyse these new technologies and security systems and to evaluate their effectiveness, practicality and impact.
Nowadays, computer software is a crucial part of the modern world. The software makes the world become smart than before. However, cyber threats using the computer software are becoming more and more of a threat in today’s smart world.Software vulnerability has been a hot topic in both academia and industry.
Choose one of the following topics:
- Trojans and Backdoor
- Viruses and Worms
- Sniffers
- Phishing
- Denial of Service
For the topic you select, you will need to research one tool attacker’s use, and one security tool used to counter attackers. Your assignment involves examining both tools, evaluating and analysing their use in meansto evade or detect threats/detection. You have to answer the followings question related to the selected attacker tool and security tool:
- Discuss how the threat actors can use the attack tool. Discuss the working mechanism.
- Demonstrate how the security tool can be used to mitigate/prevent such threat actors.
- The objective of computer security is to protect the Integrity,Confidentiality, and Availability (CIA) of information on the devices that store, manipulate, and transmit the information.Analysis the attack tool and security tool against CIA.
- Demonstrate how the threat actors can bypass detection.
- Discuss the impact of attacker threat on the individual and the society.
The importance of cryptography has increased over time tobecome a key defense in securing data from threat actors. Select any tools you are familiar with to implement one of the following cryptography algorithms:
- Elliptic Curve Cryptography (ECC)
- Diffie-Hellman key exchange
In your report, you have to provide detail for the install, run and demonstrate the use of cryptography algorithm, producing some output or results. You should analyse and evaluate the usage of the cryptography algorithm. You need to provide a complete beginning to end, tutorial like presentation of the experiment, including screen shots, this could look like a manual or a journal.
In completing this assessment successfully, you will be able to investigate IS security, risk threats and propose the suitable security controls, which will help in achieving ULO-3, and ULO-4.
