Top 20 Endpoint Security Interview Questions and Answers

1. What is Endpoint Security?

Defending network endpoints, like PCs and mobile phones, against online attacks is known as endpoint security.

2. What are the main components of Endpoint Security?

The main components of endpoint security include:

1. Antivirus/Antimalware,
2. Firewalls,
3. Endpoint Detection and Response (EDR),
4. Data Loss Prevention (DLP),
5. Encryption,
6. Application Control,
7. Device Control,
8. Patch Management,
9. User and Device Authentication and
10. Mobile Device Management (MDM).

3. How does Endpoint Security differ from Network Security?

The following are the ways that network security and endpoint security are different:

1. Focus: While network security seeks to safeguard the entire network infrastructure, including data transmission and network devices, endpoint security concentrates on safeguarding specific devices (endpoints), such as PCs, smartphones, and tablets.
2. Scope: Endpoint security entails protecting each device’s data and apps, controlling threats unique to that device, and guaranteeing that the device is compliant. In contrast, network security includes more comprehensive methods to safeguard data flow and access control throughout the network, such as firewalls, intrusion detection systems (IDS), and virtual private networks (VPNs).
3. Threat Management: Endpoint security guards against malware, ransomware, and illegal access, among other threats that directly target devices. The primary goal of network security is to thwart denial-of-service (DDoS) attacks, man-in-the-middle attacks, and network intrusion attempts that exploit network vulnerabilities.

4. What is an Endpoint Detection and Response (EDR) system?

A cybersecurity solution called an Endpoint Detection and Response (EDR) system continuously monitors and gathers data from endpoints to identify, look into, and address advanced threats and security incidents.

To defend against sophisticated attacks, it offers real-time visibility, analysis, and remediation capabilities.

5. Can you explain the concept of Zero Trust in Endpoint Security?

In endpoint security, zero trust is a paradigm that constantly validates each access request and assumes that no device, user, or network component is intrinsically trustworthy.

Strict identity verification, least-privilege access, and ongoing threat monitoring are necessary.

6. What are some common endpoint vulnerabilities?

Common endpoint vulnerabilities include:

1. Unpatched Software,
