1. The number of cyber-attacks is increasing substantially. Cyber-attacks target government, military, public and private sector, and focus on individuals and organizations to extract valuable information. Most of these attacks use malicious software (also called malware) to infect their targets. It is therefore important to have the knowledge, skills, and tools to analyse malicious software to detect, investigate and defend against these attacks. Based on your understanding of malware analysis, answer the following questions: i) Comment on the role of malware in cyber-attacks. ii) Define and discuss malware analysis, and the primary motive for conducting malware analysis. iii) Why must malware analysis be conducted in an isolated environment? Justify your answer. iv) Define and evaluate the classification techniques for malware analysis.
