OWASP Top 10 Every Small Business Should Know

What is OWASP Top 10?

OWASP (Open Worldwide Application Security Project) is a global nonprofit focused on web application security. The OWASP Top 10 is a regularly updated list of the most critical web application security risks.

For SMBs and freelance developers, implementing every security measure at once isn't realistic. But understanding the OWASP Top 10 lets you prioritize the highest-impact risks first.

3 Risks That Deserve Your Attention

1. Injection Attacks

SQL injection and command injection occur when user input is passed directly to database queries or system commands.

// Dangerous
const query = `SELECT * FROM users WHERE email = '${email}'`;

// Safe
const query = 'SELECT * FROM users WHERE email = $1';
const result = await db.query(query, [email]);

Fix: Use parameterized queries and always sanitize user input.

2. Broken Authentication

Session management flaws, weak password policies, and improper token storage lead to account takeover.

Checklist:

• Are session timeouts properly configured?
• Are passwords hashed with secure algorithms like bcrypt?
• Are JWT tokens properly validated?

3. Sensitive Data Exposure

API keys and database credentials hardcoded in source code is a surprisingly common problem.

Fix:

• Use environment variables
• Exclude .env files from Git tracking
• Use a secrets management service
