Principle of least privilege in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the Principle of Least Privilege?

It is a security concept where users or programs are given only the minimum access rights needed to perform their tasks, reducing the risk of accidental or intentional misuse.

beginner

Why is the Principle of Least Privilege important in cybersecurity?

Because it limits the damage that can happen if an account or program is compromised, by restricting access to only what is necessary.

Give a real-life example of the Principle of Least Privilege.

A bank teller can access customer accounts to deposit money but cannot approve large loans, which only managers can do. This limits what each role can do.

How does the Principle of Least Privilege help prevent malware spread?

If a program or user has limited access, malware running under that user cannot access or damage parts of the system beyond those limits.

intermediate

What is a common challenge when implementing the Principle of Least Privilege?

Balancing security with usability, because too few privileges can prevent users from doing their jobs efficiently, while too many increase risk.

What does the Principle of Least Privilege mean?

A Users get only the access they need to do their work

B Users get full access to all system resources

C Users share passwords to increase access

D Users have no access to any resources

The principle means limiting access rights to only what is necessary for tasks.

Which of these is a benefit of applying the Principle of Least Privilege?

A Increases system complexity

B Allows users to bypass security

C Reduces risk of accidental damage

D Removes all user restrictions

Limiting privileges reduces the chance of accidental or malicious damage.

Who should have administrative privileges in a system following the Principle of Least Privilege?

A No one at all

B All users by default

C Every user for convenience

D Only users who need to perform admin tasks

Only users who require admin rights for their job should have them.

What can happen if users have more privileges than needed?

A Increased risk of security breaches

B Better system performance

C Faster task completion always

D No impact on security

Excess privileges can lead to greater damage if accounts are compromised.

Which of these is NOT a way to enforce the Principle of Least Privilege?

A Using role-based access control

B Giving all users full admin rights

C Granting temporary access when needed

D Regularly reviewing user permissions

Giving all users full admin rights violates the principle.

Explain the Principle of Least Privilege and why it is important in cybersecurity.

Think about how giving only necessary access helps protect systems.

Describe a real-world example where the Principle of Least Privilege is applied.

Consider jobs like bank tellers, managers, or IT staff.
