Endpoint Detection and Response (EDR) in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Endpoint Detection and Response (EDR)?

EDR is a cybersecurity technology that monitors and collects data from endpoints like computers and devices to detect, investigate, and respond to cyber threats in real time.

beginner

Name two main functions of EDR systems.

1. Detect suspicious activities on endpoints.<br>2. Respond to threats by alerting or taking action to stop attacks.

How does EDR differ from traditional antivirus software?

Traditional antivirus mainly looks for known malware signatures, while EDR continuously monitors behavior on endpoints to detect unknown or advanced threats and provides tools to respond quickly.

Why is real-time monitoring important in EDR?

Real-time monitoring helps detect threats as they happen, allowing faster response to stop attacks before they cause serious damage.

beginner

Give an example of a response action an EDR system might take.

An EDR system might isolate an infected device from the network to prevent the spread of malware.

What does EDR primarily monitor?

A Email servers only

B Network routers only

C Endpoints like computers and devices

D Physical security cameras

EDR focuses on monitoring endpoints such as computers, laptops, and other devices.

Which of the following is NOT a typical feature of EDR?

A Automatic software updates

B Real-time threat detection

C Threat investigation tools

D Response actions to stop attacks

Automatic software updates are usually handled by other systems, not EDR.

How does EDR help improve cybersecurity?

A By replacing all antivirus software

B By detecting and responding to threats quickly on endpoints

C By blocking all internet access

D By encrypting all files automatically

EDR improves security by quickly detecting and responding to threats on endpoints.

Which action might an EDR system take when it detects malware?

A Turn off the device permanently

B Delete all files on the device immediately

C Send spam emails to users

D Isolate the infected device from the network

Isolating the device helps prevent malware from spreading.

Why is continuous data collection important for EDR?

A It helps detect unusual behavior over time

B It slows down the device

C It deletes old files automatically

D It replaces the need for passwords

Continuous data collection allows EDR to spot suspicious patterns and threats.
