Information Security Questions
Which of the following is NOT a common method for detecting security incidents?
-
Security information and event management (SIEM) systems
-
Intrusion detection systems (IDS)
-
Vulnerability scanners
-
Penetration testing
D
Correct answer
Explanation
Penetration testing is not a common method for detecting security incidents. It is a proactive measure that is used to identify vulnerabilities in a system before they can be exploited.
Which of the following is NOT a common method for eradicating security incidents?
-
Antivirus software
-
Malware removal tools
-
Patch management
-
Vulnerability assessment
D
Correct answer
Explanation
Vulnerability assessment is not a common method for eradicating security incidents. It is a proactive measure that is used to identify vulnerabilities in a system before they can be exploited.
Which of the following is NOT a common type of security incident?
-
Malware attacks
-
Phishing attacks
-
Denial-of-service attacks
-
Vulnerability assessments
D
Correct answer
Explanation
Vulnerability assessments are not a common type of security incident. They are a proactive measure that is used to identify vulnerabilities in a system before they can be exploited.
Which of the following is NOT a common component of an intrusion detection system (IDS)?
-
Sensors
-
Console
-
Reporting system
-
Vulnerability scanner
D
Correct answer
Explanation
A vulnerability scanner is not a common component of an intrusion detection system (IDS). It is a proactive measure that is used to identify vulnerabilities in a system before they can be exploited.
Which of the following is NOT a common type of vulnerability assessment?
-
Network vulnerability assessment
-
Host vulnerability assessment
-
Application vulnerability assessment
-
Penetration testing
D
Correct answer
Explanation
Penetration testing is not a common type of vulnerability assessment. It is a proactive measure that is used to identify vulnerabilities in a system before they can be exploited.
Which of the following is NOT a key component of an incident response plan?
-
Incident detection and analysis
-
Incident containment and eradication
-
Incident recovery and restoration
-
Incident prevention and mitigation
D
Correct answer
Explanation
Incident prevention and mitigation are not key components of an incident response plan. They are part of a proactive approach to cybersecurity, which aims to prevent incidents from happening in the first place.
What is the first step in an incident response plan?
-
Incident detection and analysis
-
Incident containment and eradication
-
Incident recovery and restoration
-
Incident communication and coordination
A
Correct answer
Explanation
The first step in an incident response plan is to detect and analyze the incident. This involves identifying the type of incident, the scope of the incident, and the potential impact of the incident.
Which of the following is NOT a common method for containing an incident?
-
Isolating affected systems
-
Disabling user accounts
-
Patching vulnerable systems
-
Rolling back to a previous system state
C
Correct answer
Explanation
Patching vulnerable systems is not a common method for containing an incident. It is a preventive measure that can be taken to reduce the risk of an incident occurring in the first place.
What is the final step in an incident response plan?
-
Incident detection and analysis
-
Incident containment and eradication
-
Incident recovery and restoration
-
Incident communication and coordination
D
Correct answer
Explanation
The final step in an incident response plan is to communicate and coordinate with stakeholders. This includes providing updates on the status of the incident, coordinating the response effort, and communicating with the media.
Which of the following is NOT a common type of incident response metric?
-
Mean time to detect (MTTD)
-
Mean time to respond (MTTR)
-
Mean time to recover (MTTR)
-
Cost per incident
D
Correct answer
Explanation
Cost per incident is not a common type of incident response metric. It is a financial metric that can be used to measure the overall cost of an incident.
What is the most important factor to consider when developing an incident response plan?
-
The size of the organization
-
The industry the organization operates in
-
The specific threats that the organization faces
-
The budget of the organization
C
Correct answer
Explanation
The most important factor to consider when developing an incident response plan is the specific threats that the organization faces. This will help to ensure that the plan is tailored to the organization's unique needs.
Which of the following is NOT a common type of incident response tool?
-
Security information and event management (SIEM) system
-
Vulnerability scanner
-
Incident response platform
-
Penetration testing tool
D
Correct answer
Explanation
Penetration testing tools are not a common type of incident response tool. They are used to identify vulnerabilities in an organization's systems and networks.
Which of the following is NOT a common type of incident response policy?
-
Incident reporting policy
-
Incident response escalation policy
-
Incident containment policy
-
Incident recovery policy
C
Correct answer
Explanation
Incident containment policy is not a common type of incident response policy. It is a specific type of policy that defines the steps that should be taken to contain an incident.
Which of the following is a common application of number theory in cryptography?
-
Public-key cryptography
-
Symmetric-key cryptography
-
Hash functions
-
Digital signatures
A
Correct answer
Explanation
Public-key cryptography, also known as asymmetric cryptography, is a cryptographic system that uses a pair of keys, a public key and a private key, to encrypt and decrypt messages.
Which of these is an example of a number-theoretic algorithm used in practice?
-
RSA algorithm
-
Diffie-Hellman key exchange
-
Elliptic curve cryptography
-
All of the above
D
Correct answer
Explanation
The RSA algorithm, Diffie-Hellman key exchange, and elliptic curve cryptography are all examples of number-theoretic algorithms that are widely used in practice for secure communication and data protection.
