OWASP Top 10 Explained with Examples (2023)

Показать описание

In this video about web application security we're going to walk you through top 10 of the most common web application attacks - the OWASP Top 10 vulnerabilities. This video won't be a web application development tutorial, however, once you watch this owasp top 10 2021 video you will be better equipped to build safer web application architecture.

The owasp top 10 vulnerabilities we will be covering are updated as of 2023, but this list won't be a owasp top 10 2023 list - it will cover the owasp top 10 2021 edition of OWASP. The security vulnerabilities we will cover are as follows:

1) OWASP Top 10 Broken Access Control: this security vulnerability moved up from the 5th place in 2017 into the first in 2021. To avoid the broken access control vulnerability, ensure that all existing accounts within your SQL database use only the privileges that are required to perform their actions - avoid granting unnecessary privileges.

2) Cryptographic Failure Vulnerability: to tackle this security vulnerability, make sure to store all passwords in your database in a Blowfish, BCrypt, or similar hash format.

3) SQL Injection: to avoid owasp top 10 injection attacks, make sure that all of the users within your database have proper access controls in place, and always validate user input.

4) Insecure Design: to avoid issues related to system design, make sure to plan your error messages, and your entire application and SQL database design carefully. That way you will stay a step ahead of the attacker.

5) Security Misconfiguration: this owasp top 10 2021 security flaw is also very significant. For proper security configuration, follow proper security measures, also categorize your accounts and keep an eye on reserved accounts, roles, password management, and security plugins in MySQL and other database management systems.

6) Vulnerable and Outdated Components: to avoid the vulnerable and outdated components attack, avoid using old and outdated components within your database and application, always check them for integrity and make sure to patch your systems frequently. You don't want your application to be used as an vulnerable and outdated components example.

7) Identification and Authentication Failures: to avoid the broken authentification vulnerability, make sure to design registration and login forms securely so that attackers don't have a chance to impersonate the users within your application or pass fake session IDs to log in. Also store passwords in a secure format such as Blowfish or BCrypt.

8) Software and Data Integrity Failures: to protect against integrity violations, make use of subresource integrity (SRI) features within stylesheets and javascript files, enforce code reviews, follow GDPR, and use secure repositories to securely store data. Backup your data and make sure to test your backups as well.

9) Security Logging and Monitoring Failures: monitor the activity within your application and databases carefully. If you're a user of MySQL server, its Enterprise suite of plugins can help your MySQL installation immensely, and you should also consider employing other measures to keep up with what's happening within your application to avoid incidents related to a owasp security misconfiguration.

10) Server-Side Request Forgery (SSRF): to avoid these owasp security risks, whitelist the IP addresses and DNS names your application and database needs to access. Also, keep in mind that a SSRF attack is not the same as a CSRF attack.

We hope that this video about 2021 OWASP Top 10 vulnerabilities helped you protect your applications. If it did, consider exploring some of our older videos as well:
