Why container security matters in Docker - Quick Recap

Recall & Review

beginner

What is container security?

Container security means protecting containers from threats like hacking, data leaks, and malware to keep applications safe.

beginner

Why are containers popular in software development?

Containers let developers package apps and all their parts together so they run the same everywhere, making work faster and easier.

beginner

Name one risk of not securing containers.

If containers are not secure, attackers can steal data, break the app, or use the system for bad actions.

How can container security protect your system?

It stops unauthorized access, keeps data safe, and ensures apps run as expected without interference.

intermediate

What is a common practice to improve container security?

Using trusted images, scanning for vulnerabilities, and limiting container permissions helps keep containers safe.

Why is container security important?

A To reduce container size

B To make containers run faster

C To increase container startup time

D To protect apps and data from attacks

Container security protects apps and data from attacks and unauthorized access.

What can happen if containers are not secured?

A Attackers can access sensitive data

B Containers will automatically update

C Apps will run without errors

D Containers will use less memory

Unsecured containers can be exploited to access sensitive data.

Which is a good practice for container security?

A Use trusted images

B Disable all security checks

C Run containers as root always

D Ignore vulnerability scans

Using trusted images helps avoid vulnerabilities and improves security.

Containers help developers by:

A Making apps slower

B Increasing hardware needs

C Packaging apps to run the same everywhere

D Removing all security

Containers package apps with all parts so they run consistently on any system.

Limiting container permissions helps to:

A Disable logging

B Reduce security risks

C Allow unlimited access

D Make containers larger

Limiting permissions reduces the chance of attackers doing harm if they get in.
