Endpoint Security Fundamentals for the CCNA Exam
Endpoint security protects end-user devices using antimalware, host-based firewalls, and Cisco Advanced Malware Protection (AMP) to detect and block threats.
The Role of Antivirus and Antimalware
Traditional antivirus relies on signatures to identify known threats. Modern antimalware uses heuristics and behavioral analysis to detect zero-day attacks.
Host-Based Firewalls
Host-based firewalls run on individual endpoints (like Windows Defender Firewall). They protect the device from network threats when connected to untrusted networks.
Cisco Advanced Malware Protection (AMP)
Cisco AMP provides continuous analysis and retrospective security. If a file is later deemed malicious, AMP can trace its path and quarantine it across the network.
❓ Frequently Asked Questions
What is endpoint security?
Protecting the devices that connect to the corporate network, such as laptops and mobile phones.
Why are host-based firewalls necessary?
To protect individual endpoints, especially when they connect to public or untrusted networks.
What unique feature does Cisco AMP provide?
Retrospective security, allowing it to track and remediate files that were initially considered safe but later found to be malicious.
