2. Creeper is widely considered the first computer virus/worm, created in ____.

Creeper, developed in 1971 by Bob Thomas at BBN Technologies, is recognized as the first computer virus or worm. It was designed to move across ARPANET, the precursor to the internet, and displayed a message: "I'm the creeper, catch me if you can!" Unlike modern viruses, Creeper did not cause harm but demonstrated the potential for self-replicating programs. Its creation marked a significant milestone in computer science, highlighting both the possibilities and risks associated with networked computing.

3. What caused the CrowdStrike Outage in 2024?

A ransomware attack on global servers

A faulty security update that crashed 8.5 million Windows systems

A phishing worm sent via email

A denial-of-service attack on cloud infrastructure

In 2024, a widespread outage at CrowdStrike was attributed to a faulty security update that inadvertently affected a significant number of Windows systems. This update, intended to enhance security measures, instead led to system crashes for approximately 8.5 million devices. Such incidents highlight the risks associated with deploying updates without thorough testing, emphasizing the importance of robust quality assurance processes in software development and deployment to prevent widespread disruptions.

4. What does 'Curiosity' refer to in the context of cybersecurity?

A NASA rover used to explore cybersecurity threats

The desire to ask 'why' and 'how' that leads someone to reverse-engineer systems

A tool used to detect malware on networks

A certification required for ethical hackers

In cybersecurity, 'Curiosity' embodies the intrinsic motivation to explore and understand the underlying mechanisms of systems and threats. This inquisitive mindset drives individuals to ask critical questions about how systems operate and why vulnerabilities exist. By fostering a desire to investigate and reverse-engineer, cybersecurity professionals can uncover weaknesses, develop better defenses, and enhance overall security measures. This proactive approach is essential for identifying potential threats and improving resilience against cyber attacks.

5. Cyber Ethics refers to the code of moral behavior, responsibilities, and legal boundaries governing the use of computers, networks, and digital resources.

True

False

Cyber Ethics encompasses the principles and guidelines that dictate how individuals and organizations should conduct themselves in the digital realm. It addresses issues such as privacy, security, intellectual property, and the ethical use of technology. By establishing a framework for responsible behavior online, Cyber Ethics aims to protect users and promote a safe and fair digital environment. Understanding these ethical standards is essential for navigating the complexities of technology and ensuring that actions taken in cyberspace are aligned with societal values and legal requirements.

6. What are Cyber Threat Maps?

Physical maps showing the location of cybersecurity companies

Real-time, visual representations of global cyber activity showing active attacks

Documents listing known malware signatures

Diagrams of network infrastructure vulnerabilities

Cyber Threat Maps provide a dynamic overview of ongoing cyber threats around the world. They visually represent real-time data on active cyber attacks, illustrating where and how these incidents are occurring. This information is crucial for cybersecurity professionals and organizations as it helps them understand the current threat landscape, identify potential vulnerabilities, and respond proactively to mitigate risks. By visualizing cyber activity, these maps serve as valuable tools for awareness and strategic planning in cybersecurity efforts.

7. The ILOVEYOU worm infected over 50 million computers by emailing itself to a victim's entire address ____.

The ILOVEYOU worm spread rapidly by exploiting a common feature in email programs that allowed it to access a user's entire address book. Once a user opened the infected email attachment, the worm would automatically send copies of itself to all contacts in the user's address book, leading to widespread infection. This method of propagation was particularly effective because it appeared to come from trusted sources, encouraging recipients to open the email and inadvertently spread the worm further.

8. Which of the following are examples of Defenses Against Hacking?

Firewalls

Encryption

Security awareness training

Phishing emails

Firewalls act as barriers between trusted internal networks and untrusted external networks, monitoring and controlling incoming and outgoing traffic. Encryption secures data by converting it into a code, making it unreadable to unauthorized users. Security awareness training educates individuals about potential threats and safe practices, empowering them to recognize and respond to hacking attempts. In contrast, phishing emails are a method used by hackers to deceive individuals, rather than a defense mechanism.
