Information Security Questions
What is the role of multi-factor authentication (MFA) in e-commerce security?
-
To require users to provide multiple forms of identification when logging in
-
To block unauthorized access to a website or web application
-
To detect and prevent malicious activity on a website
-
To encrypt data transmitted between a website and a user's browser
A
Correct answer
Explanation
Multi-factor authentication (MFA) is a security measure that requires users to provide multiple forms of identification when logging in to an account. This makes it more difficult for unauthorized individuals to gain access to a user's account, even if they have obtained the user's password.
What is the best practice for creating strong passwords in e-commerce?

Use a combination of upper and lowercase letters, numbers, and symbols
-
Use the same password for all online accounts
-
Keep passwords simple and easy to remember
-
Share passwords with friends and family
A
Correct answer
Explanation
Strong passwords should be at least 12 characters long and should include a combination of upper and lowercase letters, numbers, and symbols. Avoid using common words or phrases, and do not reuse passwords across multiple accounts.
What is the purpose of a web application firewall (WAF) in e-commerce security?
-
To filter and block malicious traffic at the network level
-
To detect and prevent unauthorized access to a website or web application
-
To encrypt data transmitted between a website and a user's browser
-
To scan websites and web applications for vulnerabilities
A
Correct answer
Explanation
A web application firewall (WAF) is a security device that is placed in front of a website or web application to filter and block malicious traffic at the network level. It can help to protect against a variety of cyberattacks, including SQL injection, cross-site scripting (XSS), and distributed denial-of-service (DDoS) attacks.
What is the role of regular security audits in e-commerce security?
-
To identify and fix vulnerabilities in a website or web application
-
To improve website speed and performance
-
To increase website traffic and sales
-
To prevent unauthorized access to a website's content
A
Correct answer
Explanation
Regular security audits are essential for identifying and fixing vulnerabilities in a website or web application. These audits should be conducted by qualified security professionals who can assess the website or web application for potential security risks and recommend appropriate remediation measures.
What is the best practice for handling customer data in e-commerce?
-
Store customer data in plain text format
-
Encrypt customer data before storing it
-
Share customer data with third parties without their consent
-
Keep customer data indefinitely
B
Correct answer
Explanation
Customer data should be encrypted before storing it to protect it from unauthorized access and theft. Encryption involves converting data into a format that is difficult to read or understand without the appropriate key.
What is the purpose of a security incident response plan (IRP) in e-commerce?
-
To outline the steps to be taken in the event of a security incident
-
To improve website speed and performance
-
To increase website traffic and sales
-
To prevent unauthorized access to a website's content
A
Correct answer
Explanation
A security incident response plan (IRP) is a document that outlines the steps to be taken in the event of a security incident, such as a data breach or cyberattack. The IRP should include procedures for detecting, responding to, and recovering from security incidents.
What is the purpose of a content delivery network (CDN) in e-commerce security?
-
To improve website speed and performance
-
To detect and prevent unauthorized access to a website or web application
-
To encrypt data transmitted between a website and a user's browser
-
To scan websites and web applications for vulnerabilities
A
Correct answer
Explanation
A content delivery network (CDN) is a system of distributed servers that deliver content to users based on their geographic location. This can help to improve website speed and performance, especially for users who are located far from the origin server. CDNs can also help to mitigate the impact of DDoS attacks by distributing traffic across multiple servers.
What is the role of regular software updates in e-commerce security?
-
To fix security vulnerabilities and improve software performance
-
To improve website speed and performance
-
To increase website traffic and sales
-
To prevent unauthorized access to a website's content
A
Correct answer
Explanation
Regular software updates are essential for fixing security vulnerabilities and improving software performance. E-commerce businesses should ensure that they are running the latest versions of all software, including operating systems, web servers, and e-commerce platforms. This can help to reduce the risk of cyberattacks and improve the overall security of the e-commerce website.
