30 Endpoint Security Interview Questions and Answers

1. What is endpoint security and why is it crucial in today’s threat landscape?

Protecting network-connected devices, including servers, laptops, and smartphones, from online attacks is known as endpoint security. It entails protecting endpoints from malware attacks, illegal access, and data breaches. Following are some of the reasons for the necessity of endpoint security in today’s threat landscape:

1. Remote Workforces: Devices outside of the conventional network perimeter are protected by endpoint security.
2. Sophisticated Cyberattacks: Endpoint security protects Devices from targeted attacks and zero-day threats.
3. Data Breaches and Financial Loss: Endpoint security lowers financial risks and stops illegal access to private information.
4. Compliance and Regulatory Requirements: Organizations can meet industry-specific compliance standards with the aid of endpoint security.
5. Business Continuity: Endpoint security reduces downtime and data loss to guarantee continuous operations.

2. What are the three main types of endpoint security?

Following are the 3 main types of endpoint security:

1. Antivirus and Antimalware: Shields gadgets from threats like ransomware, malware, and viruses.
2. Endpoint Detection and Response (EDR): Recognizes and reacts to sophisticated threats, such as zero-day attacks.
3. Firewall: Keeps an eye on and regulates network traffic to stop illegal access and data breaches.

3. What is an endpoint security framework?

A thorough method for protecting devices and data is called an endpoint security framework. It describes technologies, protocols, and policies to defend endpoints against online attacks. By ensuring uniform security procedures across all devices, this framework reduces risks and vulnerabilities.

4. What is an endpoint in SOC?

Any device that connects to a network is referred to as an endpoint in a Security Operations Center (SOC). Computers, laptops, tablets, smartphones, servers, and Internet of Things devices are all included in this. Because these endpoints could be used as entry points for cyberattacks, their security is essential to the overall safety of the network.

5. Is VPN an endpoint security?

VPNs are not a stand-alone endpoint security solution, even though they can improve endpoint security by encrypting traffic. Their main applications are network privacy and secure remote access.

6. What is API endpoint security?

By putting authentication, authorization, rate limiting, and other security measures in place, API endpoint security guards against illegal access, data breaches, and other online dangers.

7. Is an endpoint a URL?

No, a URL is not an endpoint. An endpoint is a system or device that connects to a network, whereas a URL (Uniform Resource Locator) identifies a particular online resource. Endpoints can be virtual or physical, such as servers or PCs, or they can be cloud-based services.

8. What is the difference between API and endpoint?

A collection of guidelines and procedures known as an API (Application Programming Interface) enables communication between various software programs. An endpoint is a particular location where data is shared within an API. It functions similarly to a doorway that allows data to enter or leave an API.

9. How to identify API endpoints?

You can identify API endpoints in the following ways:

1. API Documentation,
2. Network Traffic Analysis,
3. Reverse Engineering,
4. Web Browser Inspection, and

10 .What are the primary threats targeting endpoints, and how have they evolved over time?

Following are some of the primary threats and the way they evolved over time:

1. Malware: Viruses, worms, and spyware are examples of traditional malware that keep evolving, getting more complex, and becoming more difficult to identify. Targeting flaws in operating systems and applications, new variants appear regularly.
2. Ransomware: Malware of this kind encrypts files and then demands a ransom to unlock them. Attacks using ransomware have increased in frequency and severity, affecting both people and businesses.
3. Phishing Attacks: Phishing emails and other social engineering techniques are used by cybercriminals to fool users into disclosing private information or downloading malicious software. Phishing attacks are increasingly complex and frequently imitate reputable companies.
4. Insider Threats: Malicious insiders can disrupt operations or steal data by taking advantage of their privileged access. Since trusted people are frequently involved, these threats can be challenging to identify and stop.
5. Supply Chain Attacks: Cybercriminals target suppliers and third-party vendors in an attempt to breach their systems and obtain private data or networks. For organizations, these attacks may have far-reaching effects.

11. Explain the key differences between traditional antivirus and next-generation antivirus (NGAV) solutions.

While NGAV employs sophisticated methods like behavioral analysis, machine learning, and sandboxing to detect and stop zero-day threats, traditional antivirus relies on signature-based detection.

2. Detection: Unusual file encryption or network traffic are examples of suspicious activity that an endpoint security solution can identify.
3. Incident Response: To stop the infection from spreading further, the security team isolates the compromised endpoint. To ascertain the extent of the damage and pinpoint the attack vector, they look into the incident.
4. Remediation: Backups are used to recover the compromised files, and the endpoint is meticulously cleaned to get rid of any remaining malware. Security patches are implemented to fix flaws that the ransomware takes advantage of.
5. Recovery and Lessons Learned: Following the restoration of regular operations, the company carries out a post-event analysis to pinpoint lessons learned and enhance security protocols.

This could entail implementing more security controls, upgrading security policies, and enhancing user awareness training.
