Security and Data Protection in Software Projects: From a Small Company Perspective

Privacy and Security
06 October 2025

In the increasingly digital world, the most valuable asset is now "data." Millions of user data, customer records, and financial data are processed daily through software systems. However, this poses a significant risk, especially for small and medium-sized businesses. These businesses, which often lack the security infrastructure of larger companies, become targets for cyberattacks.

In a software project, security shouldn't just be a feature added at the final stage; it should be an architectural element that must be considered from the very beginning of the design. Boutique software companies gain a significant advantage by maintaining a balance of both flexibility and security throughout the project development process. By 2026, data protection and cybersecurity will no longer be solely the responsibility of IT teams, but of everyone involved in the software development process.

The most fundamental steps for data security are encryption and access control. Storing user data encrypted, granting access only to authorized individuals, and actively using two-factor authentication systems make a significant difference. Secure session management (such as JWT and OAuth 2.0), especially in mobile applications, ensures the protection of user information.

These steps constitute the system's first line of defense against cyberattacks.

Another important issue is data backup and disaster recovery plans. Regular backup policies should be established to ensure the business can quickly resume operations in the event of an attack, system failure, or data loss. Cloud-based solutions offer both flexibility and cost advantages in this regard.

Small businesses often fall into the misconception that "our data isn't important." However, for cyberattackers, the most valuable asset is the system's vulnerability. Even a simple phishing email can impact a company's entire network. Therefore, raising employee awareness is an integral part of software security.

Furthermore, compliance with legal regulations like the Personal Data Protection Law (KVKK) and GDPR is not only an obligation but also a measure of brand reliability. Collecting user data with permission, establishing explicit consent mechanisms, and clarifying data retention periods are both legal and ethical requirements.

Finally, every software project should undergo regular security testing, such as pen-testing and vulnerability scanning. These tests allow you to proactively identify system vulnerabilities and take action before an attack occurs.
