Questions Related to security

Phishing is essentially another form of:

  1. Denial of service

  2. Social engineering

  3. Malware

  4. Spyware


Correct Option: B
Explanation:

Phishing is a type of social engineering attack. Social engineering attacks exploit human psychology to trick people into revealing sensitive information or clicking on malicious links. Phishing attacks typically involve sending emails or text messages that appear to be from a legitimate source, such as a bank or credit card company. The emails or text messages will often contain a link that, when clicked, will take the victim to a fake website that looks like the real website. Once the victim enters their personal information on the fake website, the attacker can steal it.

Malware, spyware, and denial of service attacks are all different types of cybersecurity attacks. Malware is software that is designed to harm a computer system. Spyware is software that is designed to collect information about a user's computer activities. Denial of service attacks are designed to make a computer system unavailable to its intended users.

Therefore, the correct answer is B. Social engineering.

Here is a table that summarizes the differences between phishing and the other three options:

Attack type Description
Phishing A type of social engineering attack that exploits human psychology to trick people into revealing sensitive information or clicking on malicious links.
Malware Software that is designed to harm a computer system.
Spyware Software that is designed to collect information about a user's computer activities.
Denial of service A type of cybersecurity attack that is designed to make a computer system unavailable to its intended users.
  1. Physical break-ins

  2. System misuse

  3. Unauthorized changes to system files

  4. SPAM


Correct Option: D
  1. Hackers

  2. Flaws

  3. Policy failures

  4. Weaknesses


Correct Option: A
Explanation:

To answer this question, the user needs to know what vulnerability is. In the context of cybersecurity, vulnerability refers to a weakness in a system that can be exploited by attackers to gain unauthorized access, cause damage, steal data, or disrupt services.

Now, let's go through each option and explain whether it gives rise to a vulnerability:

A. Hackers: This option is correct. Hackers are not a vulnerability themselves but rather a threat that can exploit vulnerabilities. They are individuals or groups who attempt to gain unauthorized access to systems or networks for malicious purposes. While hackers can cause damage if they successfully exploit a vulnerability, they are not the source of the vulnerability itself.

B. Flaws: This option is incorrect. Flaws, such as coding errors or design weaknesses, can create vulnerabilities in systems that can be exploited by attackers. Flaws are one of the primary sources of vulnerabilities and are often exploited by hackers to gain access to systems or data.

C. Policy failures: This option is incorrect. Policy failures, such as weak passwords or lack of access controls, can create vulnerabilities in systems that can be exploited by attackers. Policy failures are another source of vulnerabilities and are often exploited by hackers to gain access to systems or data.

D. Weaknesses: This option is incorrect. Weaknesses, such as outdated software or unpatched vulnerabilities, can create vulnerabilities in systems that can be exploited by attackers. Weaknesses are yet another source of vulnerabilities and are often exploited by hackers to gain access to systems or data.

Therefore, the correct answer is:

The Answer is: A. Hackers

  1. Contingency planning

  2. Change control management

  3. Business continuity planning

  4. System update management


Correct Option: B
  1. A screening router

  2. A firewall

  3. A proxy server

  4. None of the above


Correct Option: C
  1. Lack of physical access control

  2. Demonstrably insecure standards

  3. Implementation weaknesses

  4. War driving


Correct Option: A
  1. Invalidating the application session

  2. Intercepting data flowing to and from a Web application

  3. Running in a separate process and memory space

  4. Learning about the application behavior


Correct Option: A

Potential security disadvantages of virtualization include:

  1. VM layer configuration is security relevant

  2. More intrusive intrusion detection via introspection

  3. An extra layer for defense-in-depth

  4. More flexible discovery/eviction of kernel root kits


Correct Option: A
  1. Users do not update their scanners frequently enough

  2. Firewalls are not intended to detect malicious code.

  3. The purpose of a string depends upon the context in which it is interpreted

  4. The sourced code language is often unknown.


Correct Option: A
  1. Forcing buffer overflows

  2. Submitting random long strings to the application

  3. Causing underflow problems

  4. Including string specifiers in input data


Correct Option: D
