The process of finding, evaluating, and applying software updates, or patches, to address security flaws in operating systems, apps, and other software components is known as patch management.
By drastically lowering the attack surface and lowering the possibility of cybercriminals taking advantage of it, it has a direct connection to endpoint security.
14. What is the difference between endpoint security and traditional antivirus solutions?
Compared to traditional antivirus software, endpoint security offers a wider range of security features, including threat detection, response, and prevention in addition to basic malware detection.
15. What are endpoint security policies, and why are they important?
The rules and regulations that control the use and safety of every device linked to a company’s network are known as endpoint security policies. Moreover, Endpoint Security Policies are important for the following reasons:
- Reduce Risk of Breaches,
- Ensure Compliance,
- Improve Security Posture,
- Facilitate Incident Response, and
- Promote a Culture of Security.
16. How can data loss prevention (DLP) be implemented at endpoints?
Software agents that monitor and manage data flow can be used to deploy DLP at endpoints, stopping sensitive information from being copied, sent, or stored on unapproved devices or locations.
17. What is multi-factor authentication (MFA), and how does it enhance endpoint security?
MFA is a security technique that, before allowing access, asks users to present two or more pieces of identification to confirm their identity. In the following ways, MFA enhances Endpoint Security:
