OWASP Top 10 overview in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the OWASP Top 10?

The OWASP Top 10 is a list of the ten most critical web application security risks, published by the Open Web Application Security Project (OWASP). It helps developers and organizations understand and fix common security issues.

beginner

Name three common risks listed in the OWASP Top 10.

Three common risks are: Injection flaws (like SQL injection), Broken Authentication, and Cross-Site Scripting (XSS). These risks can allow attackers to steal data or take control of applications.

Why is Injection considered a critical security risk?

Injection happens when untrusted data is sent to an interpreter as part of a command or query. Attackers can trick the system to run unintended commands, leading to data theft or damage.

intermediate

What does Broken Authentication mean in the OWASP Top 10?

Broken Authentication means weaknesses in login or session management that let attackers impersonate users or steal accounts. This can happen if passwords are weak or sessions are not properly protected.

beginner

How can developers use the OWASP Top 10 to improve security?

Developers can use the OWASP Top 10 as a checklist to find and fix common security problems in their applications. It guides them to write safer code and protect users from attacks.

What organization publishes the OWASP Top 10?

A National Institute of Standards and Technology

B Internet Security Alliance

C Cybersecurity and Infrastructure Security Agency

D Open Web Application Security Project

The OWASP Top 10 is published by the Open Web Application Security Project, a nonprofit focused on improving software security.

Which of the following is an example of an Injection attack?

A Cross-Site Scripting

B Broken Authentication

C SQL Injection

D Security Misconfiguration

SQL Injection is a type of Injection attack where malicious SQL commands are inserted into queries.

Cross-Site Scripting (XSS) allows attackers to:

A Run malicious scripts in a user's browser

B Steal passwords from the server

C Bypass firewall rules

D Crash the web server

XSS lets attackers inject scripts that run in users' browsers, potentially stealing data or hijacking sessions.

Broken Authentication can lead to:

A Data encryption

B User impersonation

C Faster page loading

D Improved user interface

Broken Authentication weaknesses allow attackers to impersonate users and access their accounts.

The OWASP Top 10 is primarily intended for:

A Web application developers and security teams

B Graphic designers

C Network hardware engineers

D End users

The OWASP Top 10 helps developers and security teams understand and fix common web app security risks.

Explain what the OWASP Top 10 list is and why it is important for web security.

Think about how this list helps prevent common security problems.

Describe two common security risks from the OWASP Top 10 and how attackers exploit them.

Consider Injection and Broken Authentication as examples.
