Understanding Network Security Fundamentals

Why is network security crucial for modern organizations, and what are the potential consequences of a security breach?

• It helps in reducing the cost of internet services.

• It prevents unauthorized access and protects sensitive data, avoiding financial and reputational damage.

• It ensures faster internet speeds for all users.

• It allows for more efficient data storage solutions.

Name reasons from the module that highlight the importance of studying network security.

• To understand how to increase network speed and reduce latency.

• To protect sensitive information and ensure business continuity.

• To learn about the latest software development trends.

• To improve customer service and satisfaction.

Describe a recent trend or shift in the network security landscape mentioned in this module.

• A decrease in the use of cloud services.

• An increase in the use of artificial intelligence for threat detection.

• A decline in the number of cyber attacks.

• A shift towards using older security protocols.

Identify two common vulnerabilities in enterprise networks today and briefly explain why they pose a risk.

• Outdated software and weak passwords; they can be easily exploited by attackers.

• High-speed internet and large storage capacity; they attract more users.

• Advanced encryption and multi-factor authentication; they are difficult to manage.

• Cloud storage and mobile devices; they are too expensive to maintain.

List three types of threat actors (e.g., individuals or groups) and briefly describe their motivations.

• Hacktivists, script kiddies, and insiders; motivated by financial gain.

• Cybercriminals, nation-states, and hacktivists; motivated by political, financial, or ideological reasons.

• Script kiddies, developers, and testers; motivated by curiosity.

• Insiders, developers, and testers; motivated by job satisfaction.

Explain the difference between a “script kiddie” and a “hacktivist” in terms of skill level and motivation.

• Script kiddies are highly skilled and motivated by political reasons, while hacktivists are less skilled and motivated by curiosity.

• Script kiddies have limited skills and are motivated by curiosity, while hacktivists are more skilled and motivated by political or social causes.

• Both have high skill levels but different motivations; script kiddies are motivated by financial gain, while hacktivists are motivated by social causes.

• Both have low skill levels and are motivated by boredom.

What are “attack vectors,” and why is it important to understand them when securing a network?

• Attack vectors are types of software; understanding them helps in software development.

• Attack vectors are methods used to breach a network; understanding them helps in identifying and mitigating potential threats.

• Attack vectors are network protocols; understanding them helps in improving network speed.

• Attack vectors are types of hardware; understanding them helps in hardware maintenance.

Provide an example of a social engineering technique and explain how it exploits human behavior.

• Phishing; it exploits human trust by pretending to be a legitimate source to steal sensitive information.

• Brute force attack; it exploits weak encryption algorithms.

• SQL injection; it exploits database vulnerabilities.

• DDoS attack; it exploits network bandwidth limitations.

Outline at least three best practices for securing enterprise networks as highlighted in this module.

• Use outdated software, disable firewalls, and share passwords.

• Implement strong passwords, regularly update software, and use firewalls.

• Increase network speed, reduce storage capacity, and disable encryption.

• Share network access, use simple passwords, and avoid software updates.

How can network segmentation contribute to a stronger security posture, and what is one challenge associated with it?

• It increases network speed; the challenge is the cost of implementation.

• It isolates sensitive data to limit access; the challenge is the complexity of managing multiple segments.

• It reduces the need for encryption; the challenge is the lack of skilled personnel.

• It simplifies network architecture; the challenge is the increased risk of data loss.
