Beginner Cybersecurity Interview Questions
Are you new to cybersecurity? We’ve got you covered. The following cybersecurity interview questions for freshers will help demonstrate your readiness for the junior-level position and set the foundation for your career goals in the field.
They cover fundamental concepts like encryption, authentication methods, basic types of cyber threats, and key security tools. Let’s have a look:
#1. What is encryption, and how does it work?
Sample Answer:
[box]
“Encryption is the process of converting data into a coded format that can only be read if a person has the decryption key.
An early example is the Ceaser Cipher, where each letter in a message shifts forward by a set number of places in the alphabet. Think of replacing every A with I, every B with J, etc. In this case, the “key” of the encryption would be “forward 8.”
Today, encryption is much more advanced, using complex keys that are harder to crack without the right decryption key.”

#2. What is multi-factor authentication (MFA)?
“Multi-factor authentication is a method of securing data and applications requiring users to provide multiple credentials to verify their identity. Instead of just entering a password, the user might also need to enter a code sent to their phone or use a fingerprint scan.
This extra step makes it much harder for hackers to gain access, even if they know the password.”
#3. What is the difference between a virus and malware?
“A virus is a type of malware that replicates itself, spreads to other computers through user actions, and can sometimes disrupt systems.
Malware is a broader term, covering all harmful software that can spread through network vulnerabilities or malicious code.
Signs of malware infection include slow performance, unexpected sounds, changes in files, sudden disk space shortages, and unprompted pop-up windows. In summary, all viruses are malware, but not all malware are viruses.”
#4. What is a firewall, and why is it important?
“A firewall is software or hardware that protects a network or computer from unauthorized access. Like a physical firewall in buildings that prevents fire from spreading, a computer firewall blocks malicious traffic from reaching a network.
Basic firewalls filter out unwanted network traffic, while advanced types like Next-Gen Firewalls (NGFWs) and Web Application Firewalls (WAFs) analyze data packets to detect and block threats before they reach a server.”
#5. What is a VPN, and how does it secure connections?
“A VPN, or Virtual Private Network, creates an encrypted connection between a device (like a phone or laptop) and the internet, enhancing the security of online activity.
It sends data through a private tunnel to the VPN server before reaching the internet, adding a layer of security that makes tracking harder.
A VPN is crucial for improving online security and privacy. It encrypts the internet connection, making it harder for anyone to track activities or access data, especially on unsecured public Wi-Fi. It also allows access to restricted content and protects sensitive information.”
#6. What is a brute-force attack?
“A brute-force attack means attempting many combinations of usernames and passwords until the correct one is found—it’s a process of trial and error.
Instead of trying these directly on the login page, attackers often use stolen encrypted password hashes and run them through a list of passwords.
Brute-force attacks can be effective if passwords are weak. To prevent them, it’s key to use strong, unique passwords, enable multi-factor authentication, and limit login attempts to block suspicious activity.”
#7. Explain the difference between a threat, vulnerability, and risk in cybersecurity.
“Risk is the potential for data loss, damage, or disruption caused by a cyber threat. On the other hand, a threat increases the likelihood of such an adverse event, like a hacker exploiting a flaw in a system.
Meanwhile, a vulnerability is a weakness within applications, networks, or infrastructure that makes data and assets more susceptible to threats.”
#8. What is phishing?
“Phishing is a type of fraud where a person is tricked into voluntarily providing sensitive information, like passwords or credit card details. It falls under the broader category of hacking, which includes any unauthorized use of electronic devices.
For example, it’s considered hacking if someone pretends to be a bank to obtain login information and then uses those credentials to access an account and steal money. While no code may be involved, the deception to gain access qualifies it as hacking.”
#9. What is two-factor authentication, and why is it important?
“Two-factor authentication (2FA) is an extra layer of security that helps protect accounts, even if someone gets hold of the password. It’s designed to prevent “replay attacks,” where an attacker uses stolen login credentials to access an account.
For example, if a website’s user data is leaked or someone observes a password being entered, 2FA can block them from logging in. Even in cases where network traffic could be intercepted, 2FA adds a second verification step, like a code sent to a phone.
It works alongside a strong password to better protect against unauthorized access.”
#10. What are cookies in a web browser?
“Cookies are small files stored on a computer that retain information about website visits or activities, which websites can access during subsequent visits. They are commonly used to store user preferences or browsing history.
For example, if an item is added to a shopping cart on a website, a cookie can save that cart, allowing it to persist even after the page is closed and revisited. However, cookies can also track browsing history across different sites, potentially identifying users without direct input.
To address privacy concerns, many countries require websites to obtain user consent before using cookies.”
Advanced Cybersecurity Interview Questions
Now that we’ve covered some basic cybersecurity interview questions, it’s time to delve into more advanced ones. These questions require a deeper understanding of complex security challenges, tools, and strategies.
They include emerging technologies like blockchain, strategies for securing DevOps and hybrid cloud environments, and technical concepts like lateral movement.
Here are the cybersecurity interview questions for experienced professionals:
#1. What is forensics in cybersecurity?
“Forensics in cybersecurity is basically about understanding how various systems, including Windows, Linux, and macOS, work under the hood.
It involves knowing the file system, how memory functions, and the specifics of the New Technology File System (NTFS), such as registry, shellbags, link files, and volume shadow copies. It also requires familiarity with specialized tools like EnCase or X-Ways.
A huge part of the job—probably around 70%—is data analysis. This means using tools like grep to search for specific data and organizing the findings to trace incidents, identify breaches, and provide insights into how an attack occurred.”
#2. How do you manage security in a DevOps environment?
“Managing security in a DevOps environment involves integrating security measures throughout the development lifecycle. This includes continuous monitoring, automated security scans, and integrating security checks into CI/CD pipelines.
Properly managing sensitive information, such as using tools like HashiCorp Vault, ensures that sensitive info is stored securely. Regular software updates help protect against known vulnerabilities while enforcing the principle of least privilege, which means granting users and systems the minimum access needed to perform their tasks. This minimizes the potential impact if an account or system is compromised, reducing access risks.
These practices help maintain a secure and resilient environment without compromising the speed and flexibility of DevOps processes.”
#3. What is a lateral movement in cybersecurity?
“Lateral movement in cybersecurity refers to how an attacker moves within a network after gaining initial access, such as through a compromised user account or an exploited vulnerability in a system.
This movement involves navigating from one device or system to another, such as moving from a compromised router to a host machine or from a user’s PC to a server. This allows the attackers to explore the network, access valuable data, and identify more critical targets.
Some examples of lateral movement paths (LMPs) include internal spear phishing, Pass-the-Hash (PtH) attacks, Pass-the-Ticket (PtT) attacks, remote services exploitation, and Secure Shell (SSH) hijacking.”
#4. What is a man-in-the-middle attack, and how do you prevent it?
“A man-in-the-middle (MITM) attack occurs when a cybercriminal poses as a trusted network device, like a router, intercepting communication between users and their intended destination.
This allows the attacker to listen in on or manipulate the exchanged data.
Many online services are vulnerable to such attacks, so it’s important for users to stay vigilant.
Signs of an MITM attack can include sudden drops in network speed or missing SSL (HTTPS) encryption on websites that previously had it.
To prevent such attacks, encryption is crucial, such as using HTTPS and implementing strong authentication methods, like multi-factor authentication. Plus, using VPNs and avoiding public Wi-Fi networks can reduce the risk of these attacks.”
#5. What is the difference between symmetric and asymmetric encryption?
“Symmetric and asymmetric encryption differ in their key usage. Symmetric encryption uses a single key for both encryption and decryption, making it fast but requiring secure key sharing. It’s best for situations where both parties already trust each other.
Asymmetric encryption uses a pair of keys—one public and one private. The public key is shared openly, while the private key remains secret. It allows anyone to encrypt data using the public key, which only the private key holder can decrypt.
It’s often used for secure communication over the internet, like in Transport Layer Security (TLS), where it enables secure key exchange.”
#6. Explain what container security is.
“Container security protects containerized apps and their environments from potential malware and other vulnerabilities. It’s similar to a blockchain regarding distributed security, but the security system is divided into nodes instead of being layered.
A key aspect is image security, which involves scanning container images for vulnerabilities before deployment. Runtime protection is also crucial, as it monitors containers for unusual activity.
Network security ensures safe container communication using tools like Kubernetes Network Policies and Role-Based Access Control (RBAC). Using these tools is essential to prevent misconfigurations and ensure overall safety.”
#7. What are the best ways to manage security in a hybrid cloud environment?
“Managing security in a hybrid cloud environment involves a blend of practices from both public and private cloud security models. Key aspects include data protection, ensuring sensitive data is identified, classified, and secure across all environments, with automated processes to reduce exposed risks.
A unified identity and access management (IAM) system simplifies access control. Network security measures like VPNs help secure communication between on-premises and cloud services.
Encryption is crucial for protecting sensitive data, while perimeter security strategies, including firewalls and DDoS protection, should be coordinated across all cloud interfaces.”
#8. How would you implement a zero-day exploit detection strategy?
“Implementing a zero-day exploit detection strategy should focus on defense in depth rather than relying solely on specific tools. Since zero-day exploits are unknown until they occur, building multiple layers of security is essential.
This includes monitoring for unusual behavior across networks and systems, maintaining updated software, and using advanced threat detection systems.
Even if a zero-day target is a specific piece of software, having strong internal controls can help minimize the damage and detect anomalies quickly, reducing the exploit’s overall impact on the organization.”
#9. What is the significance of AI in cybersecurity?
“AI is revolutionary in cybersecurity, improving threat detection, automating responses, and predicting potential attacks. It can identify new and evolving threats, like zero-day vulnerabilities, faster than traditional methods.
Plus, AI helps identify unusual patterns in real time, recognizing subtle anomalies that might indicate a potential breach. Overall, the importance of AI in cybersecurity lies in faster response times, reduced risks, and a more robust security posture for organizations.”
#10. What strategies work best for securing mobile applications?
“The key strategies for securing mobile applications include using two-factor authentication and password protection. Additionally, it’s crucial to secure the software supply chain by using well-maintained and trustworthy libraries and frameworks.
Encrypting data is essential to protect sensitive information during transmission and storage. Applying the principle of least privilege reduces risk by limiting access to only necessary functions.
Finally, app shielding methods like runtime application self-protection (RASP) can prevent tampering and improve the app’s security after deployment.”
Behavioral Cybersecurity Questions
Now, let’s dive into some behavioral cybersecurity interview questions. They’re all about how you handle real-life challenges, manage priorities, and evaluate your decision-making skills in complex scenarios.
Preparing for these questions can help show off your thought process, expertise, and ability to navigate cybersecurity issues when things get tough.
Note that they also serve as scenario-based cybersecurity interview questions, requiring you to explain how you handle specific incidents.
#1. How do you prioritize vulnerabilities?
By asking this question, interviewers want to see how you assess the severity of vulnerabilities, use frameworks like CVSS, and balance technical considerations with business needs.
Sample answer:
“To prioritize vulnerabilities, I first assess their severity using the CVSS (Common Vulnerability Scoring System) to understand potential impacts. High-risk vulnerabilities that could cause critical damage or are easy to exploit get immediate attention.
I also consider the affected assets, such as prioritizing vulnerabilities on critical systems or those with sensitive data. Next, I review if any active exploits are already in the wild, as this increases the urgency.
Additionally, I factor in the business impact and potential downtime caused by each fix.”
#2. Tell us about a time you had to convince stakeholders to invest in a security solution.
With this cybersecurity interview question, the employer evaluates your communication and persuasion skills. They want to gauge if you can advocate for security measures to decision-makers.
Sample answer:
“I framed the discussion around potential risks, including lost revenue, damage to reputation, and possible legal liabilities if a breach occurred. To make the case stronger, I created a risk matrix showing the likelihood and potential impact of various vulnerabilities.
I highlighted how a security incident could lead to costly downtime, lost productivity, and negative effects on the brand. By illustrating these risks, I was able to show that the investment was far more cost-effective than dealing with the aftermath of a breach.”
