Indeed, even before the COVID-19 pandemic, which released virus-themed phishing and different attacks on corporate tech stacks, cyber-attacks were expanding worldwide at a really quick clasp. Organizations have been on edge to add candidates to their security team, implying that technologists with the correct blend of cybersecurity training and abilities have a decent possibility of getting work.
While recruiting a security engineer, businesses need to ensure they select applicants who have the technical information on information security hardware and software to guarantee their data will be remained careful in case of a disaster, regardless of whether it be an earthquake or a cyber-attack. Before going to an interview for this position, plan to answer a great deal of technical questions that will decide the degree of your comprehension of information security frameworks and how they can be utilized to ensure important data.
With cybersecurity engineer interview questions, hiring specialists and employing chiefs are looking not just for a blend of aptitudes and certifications, yet they demand critical thinking and problem-solving skills, an eagerness to learn, and the capacity to deal with unpleasant circumstances that accompany an attack surface that is quickly extending.
Our list of test questions below applies to your job as a cybersecurity engineer while additionally tending to the more extensive subject of cybersecurity in general. There are a plethora of different questions to make a completely extensive guide for you to rehearse, but the following questions should assist with setting you up for the interview.
So let’s get going:
- What is Cybersecurity?
Answer: Cybersecurity is the domain of computer security that ensures the security of web-associated systems, for example, hardware, software, electronic data, etc. from cyber-attacks.
- Define Cryptography?
Answer: Cryptography is a technique to change and transfer data in an encoded way to protect the data for whoever the data isn’t authorized.
- What are the key terms for Security?
Answer: The key terms for security are Confidentiality, Integrity, and Availability. These are also called CIA triad. These three things are viewed as the most significant parts of security. Confidentiality implies ensuring the data and the data stays between the client and organization, and not offering the data to others. Integrity implies the reliability, which alludes to genuine and exact data. Availability implies to access authorized data from a specific view.
- What is a Firewall and its purpose?
Answer: A Firewall is a security software or program that screens and controls network traffic of the framework or a network. Firewalls are basically used to ensure the security of the system/network from malware, virus, worms, etc. Firewalls are also used to thwart content filtering and remote access.
- How are VA and PT different?
Answer: Vulnerability Assessment is a strategy used to find vulnerabilities in an application/network while Penetration testing is the demonstration of finding exploitable weaknesses like an authentic attacker will do. VA is performed on a shallow level while PT is all about digging it deeper.
- What are the principals to distinguish the cyber-attack?
Answer: There are different principals to distinguish and break down cybersecurity:
- Threat: Someone with the possibility to harm by manipulating or annihilating the official data to a framework or association. The threats can be natural, unintentional, and intentional.
- Vulnerability: It implies to defects in a framework that makes threats increasingly conceivable and much progressively risky.
- Risk: It refers to the possibilities of threat and loss of data before the vulnerability is exploited.

- What is Cross-Site Scripting and how might we hinder it?
Answer: Cross-Site Scripting or XSS attack targets executing malicious scripts on a victim's internet browser by infusing malicious code. An XSS attack is also called a client-side injection attack.
- What is the TCP Three-way handshake?
Answer: It is a method used in a network to make a connection between a server and localhost. This methodology requires the server and host to organize synchronization and acknowledgment packets before the correspondence begins.
- Name some common Cyberattacks?
Answer: Dos, DDos, Man-in-the-middle (MITM), phishing, XSS attack, SQL injection, eavesdropping attack, and so forth.
- Explain Brute Force Attack and ways to counter it?
Answer: Brute Force is a strategy for finding the right credentials by continuously trying all the permutation and combination of expected credentials. Brute Force attacks are generally automated which means that the software by default attempts to log in with a list of credentials. There are different ways to thwart Brute Force attacks. Some of them are mentioned below:
Password Length: You can set a base length for a password. For example, the minimum length of a password can be 8 digits. A lengthier password is hard to crack.
Password Complexity: Complex passwords not only save brute force attacks, but they also try to shield you from various modern attacks that subtly penetrate your systems. Use all kind of characters, numbers, upper and lower case characters as this strengthen the password making it hard to be compromised.
Restricting Login Attempts: Restrict the no. of failed login attempts. For example, you can set the threshold on 3 or 5. So whenever the set no. of login attempts fails, the user will be restricted from signing in for quite a while or send an OTP to use to sign-in the next time.
- What are encoding, encryption, and hashing?
Answer: Encoding guarantees that data is organized accurately with the goal that it very well may be decrypted appropriately by applications and beneficiaries. Consider it data being changed into a plan that is effectively perused so communications are conceivable.
Encryption makes data vague to unauthorized parties with the exception of those who have the secret key for decrypting the data. Encryption makes the data secure and is used for protecting data over private connections.
Hashing is a technique that guarantees that data integrity isn’t compromised. A data hash is a string of data that is produced against the data that is being protected. By producing a hash and contrasting it with the first after transmission, you can check that the data has not changed if the hashes match. On the off chance that they don't match, then the data is no longer in its unique state and must not be trusted.
- What is a man-in-the-middle attack?
Answer: A MITM attack is done when an outsider furtively captures or diverts communications between the two parties that are speaking with each other. The attacker can infuse their own data bundles into the discussion, or they can tune in and take data without the two parties get any idea that a breach in security has happened. This happens normally on remote networks where a hacker can impersonate possibly either of the endpoints of the association.
- What is ARP and when might you use it?
Answer: ARP is Address Resolution Protocol. It is utilized when incoming packets of data that are bound for a particular host get to the gateway or router of a network. The gateway decrypts the MAC address related to the IP address that it is searching for and afterward designs the packet to the right length so the data transmission can happen. ARP then allows the correspondence to begin.
- Have you ever experienced a serious breach?
Answer: This is a question that no one but you can answer confidently. You can clarify the entirety of the situations that you have been associated with, which is an extraordinary method of exhibiting your abilities and your comprehension of acceptable behavior during a breach. How you decide to manage explicit dangers could likewise bear some significance with the interviewers, particularly if you share your experiences.
- Explain IPS and IDS?
Answer: IPS stands for Intrusion Prevention System. IPS helps in recognizing the intrusion and it will make a further move to keep it from the intrusion. IDS stands for an Intrusion detection system that helps in the location of an intrusion and after that manager of the system will make a choice for evaluation and assessment.
