In an era where cyberattacks grow more sophisticated every year, software security is no longer optional — it is a necessity. OWASP (Open Web Application Security Project) is a global community that guides developers by identifying the most critical security vulnerabilities in web applications. The OWASP Top 10 list defines the fundamental security risks every software developer must know.
OWASP Top 10 (2021 Update)
| Rank | Security Risk | Description |
|---|---|---|
| A01 | Broken Access Control | Unauthorized access and privilege escalation |
| A02 | Cryptographic Failures | Weak encryption and data leakage |
| A03 | Injection | SQL, NoSQL, OS, LDAP injection |
| A04 | Insecure Design | Design-level security deficiencies |
| A05 | Security Misconfiguration | Incorrect security configuration |
| A06 | Vulnerable Components | Components with known vulnerabilities |
| A07 | Auth Failures | Authentication and identification failures |
| A08 | Data Integrity Failures | Software and data integrity violations |
| A09 | Logging Failures | Insufficient logging and monitoring |
| A10 | SSRF | Server-Side Request Forgery |
Most Critical Vulnerabilities and Protection Methods
A01: Broken Access Control
Rising to the number one spot in the 2021 list, this vulnerability allows users to access resources they are not authorized to view.
- Protection: Apply the Principle of Least Privilege
- Perform authorization checks on every endpoint — never trust the client side
- Prevent brute force attacks with rate limiting
A03: Injection
This occurs when an attacker executes malicious code through application inputs.
query = “SELECT * FROM users WHERE id = “ + user_input
// RIGHT – Parameterized query
query = “SELECT * FROM users WHERE id = ?”
cursor.execute(query, (user_input,))
Secure Coding Principles
- Validate inputs: Validate all user inputs on the server side
- Encode outputs: Apply HTML encoding to prevent XSS attacks
- Use parameterized queries: Use ORM or prepared statements against SQL Injection
- Strong authentication: MFA, strong password policies, session management
- Encrypt sensitive data: Use AES-256, bcrypt/Argon2
- Keep dependencies up to date: Continuous scanning with Dependabot, Snyk
- Limit error messages: Never expose stack traces or system information
DevSecOps: Shifting Security Left
DevSecOps Pipeline Example
Code (SAST) → Build (SCA) → Test (DAST) → Deploy (Container Scan) → Production (RASP/WAF)
TAGUM’s Security Approach
At TAGUM, our PratikEsnaf.Net ERP platform and DeskTR support system are built on OWASP standards. All user inputs are validated server-side, database queries run as parameterized statements, and sensitive data is encrypted with AES-256. We maintain a proactive security strategy through regular penetration tests and code security scans.
Conclusion
Software security is not a feature to be bolted on afterward — it is a discipline that belongs at the foundation of design. Using the OWASP Top 10 as a guide, making secure coding practices a part of team culture, and integrating security into every stage of the process through DevSecOps are essential pillars of modern software development.
