Introduction
You cannot imagine a world without technology anymore. Take any aspect of life you want, and there is some sort of technology involved. Now, you just need to get your cell phone out, and you will get anything you want at your fingertips. Be it government bodies or multi-national corporate firms – all have welcomed the digital world with open arms.
Now imagine if everything you want is on the internet, then isn’t it something like a double-edged sword? In the way it offers convenience, it can be risky too, if proper security measures are not taken. Malicious people can try to exploit the huge amount of data that is available on the internet. When you think of it, where there is an asset, there should be protection as well. So, how do you protect the online world and everything that lies in it? The answer is through cybersecurity. It is the skill by which professionals keep organisations and personal data safe.
The role is as interesting as it sounds, and that is why many individuals dream of pursuing it as a career option. But are you worried about the cybersecurity interview questions that may come your way? Don’t worry, as this guide will look at the most common cyber security interview questions and suggest suitable answers. So, let’s get started with the first one!
Technical Knowledge and Skills Questions
Expect questions on technical skills from the interview panel, as these are very common cyber security interview questions.
1. Can you explain the difference between symmetric and asymmetric encryption?
Be prepared to explain encryption concepts with clear examples to demonstrate your understanding.
1.1. Key Concepts and Applications of Encryption Techniques
In symmetric encryption, only one key is used. This holds true for both the processes of encryption and decryption. For this reason, it is suitable for handling big data volumes. But, asymmetric encryption is different because it uses two keys. There is a public key for encrypting data, and there is a private key for decrypting. This approach provides stronger security when sharing important information.
1.2. Sample Answer
“Symmetric encryption is like having one key that can both lock and unlock a treasure chest. It works very quickly, so it is good for encrypting big amounts of data. However, sharing the same key securely between parties can be difficult. Asymmetric encryption solves this problem by using a pair of public and private keys to ensure safe key exchange. For example, SSL/TLS protocols use asymmetric encryption first to make safe connection, then they switch to symmetric encryption for sending data because it is faster.”
2. How do you stay updated with the latest cyber security threats and trends?
Going through multiple sources regularly will make sure that you get a complete and current view of what is happening in the field.
2.1. Importance of Continuous Learning and Staying Informed
Staying updated is very important in the field of cyber security. Learning all the time makes sure you know about the new dangers and technologies. This helps you use the newest safety methods properly.
2.2. Sample Answer
“I keep myself informed by using different ways. I read industry news websites like Threatpost and also listen to cyber security podcasts. I go to conferences like DEF CON where I can meet other people from my field.”
Network Security and Infrastructure Questions
Network security is important to protect the data and resources of an organisation. Questions from this domain are common cyber security interview questions.
3. Can you describe the main components of a secure network architecture?
Understanding the layered approach to network security is important to implementing effective defences.
3.1. Essential Elements and Best Practices of Network Security
A safe network setup has firewalls, systems to detect and prevent intrusions (IDS/IPS), a secure layout with different sections, and regular checks on the network.
3.2. Sample Answer
“Firewalls work like first protection layer, controlling traffic that comes in and goes out. IDS/IPS systems watch network traffic to find activities that look suspicious. Dividing the network into segments reduces how much malware can move around, and having strict rules on who can access what makes sure only approved users get in. Watching the network regularly helps to find any strange behaviour early.”
4. How would you implement a firewall to protect a corporate network?
Effective firewall management requires ongoing monitoring and adjustment to respond to evolving threats.
4.1. Firewall Configuration and Rule-Setting Techniques
Implementing a firewall involves defining clear security policies, configuring rules to block unauthorised access, and continuously updating the rules based on emerging threats.
4.2. Sample Answer
“To implement a firewall, I’d start by defining the network security policies and objectives. Next, I’d configure the firewall rules to allow only legitimate traffic and block unauthorised access. This includes setting up inbound and outbound rules, applying NAT (Network Address Translation) where necessary, and continuously monitoring and updating the rules to adapt to new threats. Regular audits and log reviews are also essential to ensure the firewall’s effectiveness.”
Incident Response and Mitigation Questions
It’s paramount to look at incident response and mitigation questions while going through the cyber security interview questions for freshers.
5. What steps would you take to investigate and respond to a security breach?
A structured response plan ensures systematic handling of security breaches.
5.1. Incident Response Plan and Procedures
An effective response involves preparation, identification, containment, and eradication.
5.2. Sample Answer
“Upon identifying a security breach, I’d activate the incident response plan. First, I’d identify and confirm the breach, then contain the affected systems to prevent further damage. Following containment, I’d eradicate the threat by removing malicious files and patching vulnerabilities. The next step is recovery, ensuring systems are restored and secured. Finally, I’d conduct a post-incident review to understand the cause, improve response strategies, and prevent future occurrences.”
6 Can you provide an example of a security incident you handled and the outcome?
When you discuss specific security incidents, you get a chance to show how good your problem-solving abilities are.
6.1. Importance of Real-World Experience and Lessons Learned
Real-world experience shows your hands-on understanding and ability to solve problems. It is important to deal with security issues.
6.2. Sample Answer
“One time I managed a ransomware attack where harmful software locked important company data. My team acted fast to separate the infected systems, stopped it from spreading more, and got the data back using backups we had. We found out how they got in, which was through a phishing email. So, we made our email filtering stronger and trained users better to stop this from happening again. This showed us how important it is to have a good incident response plan and do regular backups.”

Risk Assessment and Management Questions
While going through the cyber security interview questions and answers, one must pay special attention to risk assessment and management questions.
7. How do you conduct a risk assessment for an organisation’s IT infrastructure?
Using established frameworks ensures a thorough and structured approach to risk assessment.
7.1. Risk Assessment Frameworks and Methodologies
Conducting a risk assessment involves identifying assets and assessing threats and vulnerabilities.
7.2. Sample Answer
“I make use of frameworks such as NIST SP 800-30 to help with my risk assessments. At first, I find and sort assets into categories. Next, I check possible threats and weak points for each asset and try to understand how these risks could affect them. After that, I decide which risks are more important than the others. This I do by figuring how likely they are to happen.”
8. Can you explain the concept of “defense in depth” in cyber security?
A layered security approach is about providing more than a single point of protection. This offers a much better level of security against threats.
8.1. Layered Security Approach and Its Benefits
Defence in depth means using several levels of security measures to guard important things. This way, if one level fails, there are still other levels that can stop an attack.
8.2. Sample Answer
“Defense in depth means using several security measures at different layers, like firewalls, IDS/IPS systems, encryption tools, and training for users. This layered strategy gives strong protection by lowering the chances of an attack even if one measure does not succeed.”
Compliance and Regulatory Questions
Questions on compliance and regulation are sure to be found in the cyber security viva questions.
9. How do you ensure compliance with industry-specific security standards (e.g., HIPAA, PCI DSS)?
Being well-versed in security standards and their requirements is crucial for ensuring compliance.
9.1. Overview of Common Security Standards and Their Requirements
Compliance with standards like HIPAA and PCI DSS involves adhering to specific security requirements. This helps to protect sensitive data.
9.2. Sample Answer
“Making sure to follow rules begins with knowing guidelines such as HIPAA or PCI DSS. For HIPAA, it is important to protect PHI using technical, administrative, and physical measures. For PCI DSS, it must focus on protecting cardholder data by using strong access controls, constant monitoring, and encryption. I do regular audits, train employees often, and use automated tools to maintain compliance all the time.”
10. What experience do you have with security audits and assessments?
Regular audits help maintain and improve an organisation’s security posture.
10.1. Importance of Regular Audits and Assessments for Maintaining Security Posture
Regular audits and assessments are vital for identifying vulnerabilities and ensuring compliance with security standards.
