🔐 OWASP Top 10 – The Web Application Security Watchlist (2023)
In today’s evolving threat landscape, the OWASP Top 10 list is essential reading for every web developer and security practitioner. Here’s a breakdown of the ten most critical web application security risks, along with their descriptions, mitigations, and reference links.
1. 🧱 Broken Access Control (A01:2021)
Description: Users can access unauthorized resources—such as other users’ profiles, admin functions, or sensitive data.
Deny by default, enforce rules at server level.
- Use role-based access control (RBAC)
- Enforce authorization at every request
- Test for privilege escalation
2. 🧬 Cryptographic Failures (A02:2021)
Description: Sensitive data like passwords or credit cards are exposed due to weak or absent encryption.
Don’t roll your own crypto. Ever.
- Use HTTPS (TLS 1.2+)
- Hash passwords with bcrypt or Argon2
- Use strong and up-to-date crypto libraries
3. 💉 Injection (A03:2021)
Description: Unsanitized user input is used in queries—SQL, OS commands, or others—allowing code execution.
Sanitize input and use prepared statements.
- Use parameterized queries (e.g., PDO, ORM)
- Validate input strictly (whitelist preferred)
- Use input sanitizers (like DOMPurify for HTML)
4. 🧬 Insecure Design (A04:2021)
Description: Security issues that stem from flawed design choices—not just code bugs.
If it’s insecure by design, code fixes won’t save you.
- Perform threat modeling
- Use secure design patterns
- Include security early in the SDLC
5. 🧠 Security Misconfiguration (A05:2021)
Description: Misconfigured headers, verbose error messages, or exposed services give attackers a head start.
What’s exposed in staging stays exposed in production—unless fixed.
- Disable unused features and ports
- Set security headers (e.g., CSP, HSTS)
- Automate configuration scanning
6. 🪪 Vulnerable and Outdated Components (A06:2021)
Description: Old dependencies may contain known vulnerabilities ready for exploitation.
Outdated = unsafe. Always monitor your stack.
- Use tools like Snyk, OWASP Dependency-Check
- Patch dependencies regularly
- Remove unused packages
7. 🧩 Identification and Authentication Failures (A07:2021)
Description: Broken authentication lets attackers impersonate users and hijack sessions.
Protect the keys to your kingdom.
- Use MFA and secure session tokens
- Limit login attempts and add delays
- Don’t expose user identifiers unnecessarily
8. 🧠 Software and Data Integrity Failures (A08:2021)
Description: Relying on unsigned or untrusted software can lead to compromised updates or plugins.
Trust, but verify. Especially your software supply chain.
- Use signed packages and binaries
- Secure your CI/CD pipeline
- Scan for tampering or backdoors
9. 🧵 Security Logging and Monitoring Failures (A09:2021)
Description: Without logs or alerts, attacks go undetected—costing time and damage control later.
You can’t protect what you can’t see.
- Log authentication, validation, and errors
- Use SIEM or log aggregators
- Enable alerting for suspicious activities
10. 🎭 Server-Side Request Forgery (SSRF) (A10:2021)
Description: The server makes backend requests on behalf of the attacker—often into internal networks.
Don’t let your server become the attacker’s puppet.
- Disable unnecessary URL fetch features
- Use allow-lists for external domains
- Validate and sanitize user input URLs
