Interview Questions for IT Auditor

If you work in an IT audit team, you are technically the company’s first line of defense before the regulators. Because you want to keep your company as safe as possible from external audits, government agencies, or other organizations, you want to make sure that your company is doing the right thing, which is the primary job of an auditor.

Interviewers confirm that you have technical and soft skills, such as excellent communication and analytical abilities. So, in this article, we have compiled a list of top interview questions to help you prepare for the IT Auditor interview and ace it on the first go.

Question 1: What exactly is the difference between symmetric and asymmetric encryption?

Answer: Symmetric encryption encrypts and decrypts using the same key. Asymmetric, on the other hand, employs distinct keys for encryption and decryption.

Question 2: What are the three methods for authenticating a person’s identity?

Answer: The three ways of authenticating a person are as follows:

Question 4: How is  auditing on Windows different from  auditing on Linux?

Answer: Many tools in Windows are more automated or can be used through a Graphical User Interface (GUI). In Linux, you must utilize the command line more frequently.

In Windows, an audit policy is defined using the GPO and delivered via the domain controller. In Linux, this is typically accomplished through the/etc/audit usage, rules files and the audited service. Because of the differences in how the system gathers information for audit logs, the controls for the two settings are also distinct. In a Linux context, the ability to log into the system in single-user mode using a GRUB password is a feature that an auditor would not need to assess in a Windows environment.

Question 5: How might traceroute assist you in determining the location of a communication breakdown?

Answer: Traceroute allows you to see which routers you have impacted. You proceed to the final destination by moving along the chain of connections and determining where the line of connections ends.

Answer: A black hat hacker is one who compromises computer security for personal benefit or malevolent purposes. On the contrary, white hat hackers are ethical computer hackers who specialize in ensuring the security of a company’s information system through penetration testing and other testing procedures.

Question 8: What is XSS?

Answer: XSS or cross-site scripting is a web security flaw that allows an attacker to compromise user interactions with a susceptible application. It enables an attacker to bypass the same-origin policy intended to separate various websites.

Question 9: What is the difference between data protection at rest and data protection in transit?

Answer: Data protection at rest aims to preserve inactive data stored on any device or network. On the other hand, data protection in transit refers to the security of data while it is being transported from one network to another or from a local storage device to a cloud storage device.

Question 10: How can you safeguard your Wireless Access Point (WAP) at home?

Answer: There are several techniques to secure the home Wireless Access Point (WAP):
