8. What is a whitelisting and blacklisting approach in endpoint security?

Blacklisting just disables known dangerous apps while letting all others run, whereas whitelisting only allows pre-approved apps to run.

9. What is an application control feature in endpoint security?

An endpoint security feature called application control limits the programs that users can run, prohibiting the usage of dangerous, unapproved, or untrusted software.

10. What is a patch management feature in endpoint security?

Patch management is an endpoint security feature that closes vulnerabilities and fixes issues by automatically distributing and installing software updates and security patches on all devices.

11. What is a firewall feature in endpoint security?

In endpoint security, a firewall function keeps an eye on and regulates the device's incoming and outgoing network traffic, permitting or prohibiting connections in accordance with a set of security rules.

12. What is a vulnerability management feature in endpoint security?

An endpoint security feature called vulnerability management regularly scans and evaluates endpoints to find, rank, and report security flaws (such as unpatched software and incorrect configurations) that require fixing.

13. What is a security information and event management (SIEM) feature in endpoint security?

In order to identify, rank, and react to threats in real time, a Security Information and Event Management (SIEM) feature in endpoint security gathers, correlates, and evaluates security logs and event data from endpoints and other sources.

14. What is a mobile device management (MDM) feature in endpoint security?

A system that centrally controls, protects, and enforces rules on personal and business smartphones and tablets connected to the network is known as a Mobile Device Management (MDM) feature in endpoint security.

15. What is cloud-based endpoint security, and how does it work?

Cloud-based endpoint security is a cloud-managed solution that eliminates the need for on-premise hardware by using a lightweight agent on endpoint devices to gather data and execute protection settings centrally.

16. How to perform endpoint security testing and assessment?

A multi-step procedure is used to test and evaluate endpoint security, which includes inventorying all devices, doing penetration testing and vulnerability scanning, examining access controls and policies, and then fixing any vulnerabilities found.

17. How to implement endpoint security best practices?

You can implement endpoint security best practices in the following ways:

a) Automate Patch & Vulnerability Management,

b) Enforce Principle of Least Privilege (PoLP),

c) Deploy Modern Endpoint Detection and Response (EDR),

d) Mandate Full-Disk Encryption & Data Protection, and

e) Conduct Mandatory Security Awareness Training.

18. How to configure endpoint security policies?

In the following ways, you can configure endpoint security policies:

a) Assess Your Environment & Define the Scope,

b) Develop Core Policy Components,

c) Implement & Automate Policy Deployment,

d) Communicate & Provide Training, and

e) Monitor, Audit, & Continuously Refine.

19. How to maintain and update endpoint security solutions?

In the following ways, you can maintain and update endpoint security solutions:

a) Implement Automated Patch & Update Management,

21. How to handle endpoint security incidents and breaches?

To minimize damage and resume regular operations, adhere to a systematic incident response plan: Prepare, Identify, Contain, Eradicate, Recover, and incorporate Lessons Learned.

22. How to handle endpoint security false positives?

Examine the context of the alert, reverse any automatic remediation, make a temporary exception, send the file or activity to the vendor for whitelisting, and adjust your thresholds and detection criteria.

23. How to handle endpoint security compliance requirements?

Ensure that all endpoints are continuously monitored and auditable by implementing centralized management for required controls like encryption, MFA, automated patching, and least-privilege access.

24. How to handle endpoint security in a remote work environment?

Install Endpoint Detection and Response (EDR), Zero Trust Network Access (ZTNA), obligatory Multi-Factor Authentication (MFA), full disk encryption, and ongoing security awareness training for all remote employees as part of a layered defense approach.
