    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Use current examples like smart homes or wearables.
    • 💡Think about the attack surface of IoE devices.
    • 💡Consider both benefits and drawbacks in your answers.
    • 💡Always use correct terminology: say 'vulnerability' not 'weak spot', 'exploit' not 'hack'.
    • 💡In extended answers, structure your response with clear paragraphs: define, explain, give an example, and state the impact.
    • 💡For practical questions, show your working and include units (e.g., bits, seconds).

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing IoE with IoT or other related concepts.
    • Overlooking privacy concerns when discussing repurposing.
    • Not considering the broader societal impact of IoE.
    • Misconception: Encryption makes data completely secure. Correction: Encryption protects data in transit or at rest, but it does not protect against poor passwords, phishing, or compromised endpoints.
    • Misconception: A firewall is a complete security solution. Correction: Firewalls are just one layer; they cannot block all threats, especially those that use allowed ports or encrypted traffic.
    • Misconception: Cyber threats only come from external hackers. Correction: Insider threats (employees, contractors) are equally dangerous, whether malicious or accidental.

    How Students Lose Marks (Examiner Pitfalls)

    Common mark loss traps and how to write 100% full-mark answers

    Pitfall: Students often confuse confidentiality, integrity, and availability (CIA triad) with other security models, or fail to apply them to real-world scenarios.
    ❌ Weak Answer (Loses Marks):Confidentiality means keeping data secret, integrity means data is correct, and availability means data is accessible.
    ✅ 100% Model Answer (Full Marks):The CIA triad is a foundational model for information security. Confidentiality ensures that data is accessible only to authorised individuals, often enforced through encryption and access controls. Integrity guarantees that data is accurate and unaltered, using hashing and digital signatures. Availability ensures that data and systems are accessible to authorised users when needed, supported by redundancy and disaster recovery plans. In a scenario like an e-commerce website, confidentiality protects customer payment details, integrity ensures transaction records are not tampered with, and availability keeps the site operational during peak times.
    Examiner Tip: Always link each CIA component to a concrete example and mention specific technologies or practices that enforce it.
    Pitfall: In network security questions, students often list firewall types but fail to explain how they filter traffic or their limitations.
    ❌ Weak Answer (Loses Marks):A firewall is a security device that blocks hackers.
    ✅ 100% Model Answer (Full Marks):A firewall is a network security system that monitors and controls incoming and outgoing traffic based on predetermined security rules. Packet-filtering firewalls inspect packets at the network layer, allowing or blocking them based on source/destination IP and port. Stateful firewalls track the state of active connections and make decisions based on context. Application-layer firewalls (proxy firewalls) filter traffic at the application level, providing deeper inspection. However, firewalls cannot protect against internal threats, malware that bypasses open ports, or encrypted traffic that is not inspected.
    Examiner Tip: Describe the mechanism (how it works) and give a specific limitation to show deeper understanding.

    Step-by-Step Worked Solutions

    Detailed solution breakdown for typical exam problems

    Question: A company uses a symmetric encryption algorithm with a 128-bit key. If an attacker can try 10^12 keys per second, calculate the maximum time (in years) to brute-force the key. Show your working.

    1. 1.Step 1: Identify the total number of possible keys: 2^128.
    2. 2.Step 2: Divide the total keys by the rate of attempts per second: (2^128) / (10^12) seconds.
    3. 3.Step 3: Convert seconds to years: divide by (60*60*24*365) ≈ 3.1536 × 10^7 seconds per year.
    4. 4.Step 4: Compute the result: (2^128) / (10^12 * 3.1536 × 10^7) ≈ 1.08 × 10^22 years.
    Final Answer: Approximately 1.08 × 10^22 years, which is effectively infeasible.

    Question: Explain how a Distributed Denial of Service (DDoS) attack works and describe two mitigation strategies.

    1. 1.Step 1: Define DDoS: an attack that overwhelms a target with traffic from multiple sources, making it unavailable.
    2. 2.Step 2: Explain the mechanism: attackers use botnets (compromised devices) to send massive requests to the target server, exhausting bandwidth or resources.
    3. 3.Step 3: Mitigation 1: Rate limiting – restrict the number of requests a server accepts per second from a single IP.
    4. 4.Step 4: Mitigation 2: Traffic filtering – use firewalls or load balancers to drop suspicious traffic based on patterns or blacklists.
    5. 5.Step 5: Conclude with the goal: to maintain availability (part of CIA triad).
    Final Answer: A DDoS attack floods a target with traffic from many sources, causing service disruption. Mitigation includes rate limiting and traffic filtering.
