Understanding OWASP Top 10 for SMBs

Introduction

The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications.

For small and medium businesses, understanding these risks is crucial. While you may not have a dedicated security team, being aware of common vulnerabilities can help you make informed decisions about your web applications.

The Top 10 Risks

1. Broken Access Control

Access control enforces policy such that users cannot act outside of their intended permissions. Failures typically lead to unauthorized information disclosure, modification, or destruction of data.

2. Cryptographic Failures

Previously known as Sensitive Data Exposure, this category focuses on failures related to cryptography. This often leads to exposure of sensitive data such as passwords, credit card numbers, and personal information.

3. Injection

Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query.

What SMBs Should Do

Start with the Basics

You don't need to be a security expert to protect your business. Start by ensuring your web applications follow basic security practices:

• Keep all software and frameworks up to date
• Use strong authentication methods
• Implement proper access controls
• Encrypt sensitive data both in transit and at rest
• Validate and sanitize all user inputs
