Understanding forms of attack

• What is the primary purpose of network security?

  Protect networks and data
• What is the definition of malware?

  Malicious software
• What is social engineering in network security?

  Manipulating people
• What is the purpose of phishing attacks?

  Obtain sensitive information
• Effective network security safeguards sensitive information and prevents data breaches.

  True
• Malware includes viruses, worms, and trojans
• What is the main goal of hacking in network security?

  Gain unauthorized access
• Malware is designed to disrupt, damage, or gain unauthorized access
• How does a worm spread across a network?

  Self-replicates independently
• Ransomware demands payment for decrypting encrypted files.


  True
• A virus spreads through program execution
• Match the malware type with its description:

  Virus ↔️ Attaches to files and spreads through program execution

  Worm ↔️ Self-replicates and spreads independently

  Trojan Horse ↔️ Disguises as legitimate software

  Spyware ↔️ Collects user data without consent

  Ransomware ↔️ Encrypts files and demands payment
• Network security aims to protect data from unauthorized access, misuse, and disruption.


  True
• Social engineering involves manipulating people to reveal sensitive information
• Which type of attack overwhelms a network with traffic to make it unavailable to legitimate users?

  Denial-of-Service (DoS)
• Match the malware type with its example:

  Virus ↔️ Chernobyl virus

  Worm ↔️ WannaCry ransomware

  Trojan Horse ↔️ Zeus banking trojan
• What is the primary goal of phishing attacks?

  Trick users into revealing data
• An email impersonating a bank requesting account details is an example of phishing.


  True
• Trojans are a type of malware that disguise themselves as legitimate software to trick users into installing
• Match the feature with its corresponding category:

  Access Method ↔️ Bypasses normal security measures ||| Disguises itself as legitimate software

  Purpose ↔️ Gain remote control of the system ||| Provide backdoor access and enable further attacks
• Network Security ensures the confidentiality, integrity, and availability of network resources and data
• Confidentiality in network security means protecting data from unauthorized disclosure.


  True
• What is an example of hacking?

  Exploiting software vulnerabilities
• Social Engineering involves manipulating people into revealing sensitive information
• What is the primary purpose of malware?

  Gain unauthorized access
• A trojan horse disguises itself as legitimate software to trick users.


  True
• DDoS attacks use multiple compromised systems to amplify the attack's impact
• What is the primary goal of phishing?

  Acquire sensitive information
• Social engineering relies on psychological manipulation and trust
• What is the purpose of a Trojan in a cyber attack?

  Provide backdoor access
• Trojans facilitate backdoor access, making them a significant network security threat.

  True
• What type of vulnerability does SQL injection exploit?

  SQL queries
• A data breach involves the unauthorized access, disclosure, or theft
• What is an example of a data breach caused by phishing?

  Employees providing login credentials
• Network security is crucial for maintaining system availability and preventing data breaches.


  True
• Denial-of-Service attacks overwhelm a network with traffic
• Threats to computer systems can compromise data confidentiality and integrity.


  True
• Ransomware encrypts a victim's files and demands payment
• What is the primary function of a Denial-of-Service (DoS) attack?

  Make systems unavailable
• Social engineering involves manipulating people to compromise security.
