Frequently Asked Questions

What are the biggest cybersecurity threats in 2025?

The biggest cybersecurity threats in 2025 are AI-powered attacks, ransomware, phishing, zero-day vulnerabilities, and supply chain attacks. Artificial intelligence enables attackers to carry out more sophisticated and personalized attacks. Zero Trust architecture and continuous monitoring are critical against these threats.

What security measures should be taken for cybersecurity?

For cybersecurity, multi-factor authentication (MFA), regular security updates, security awareness training, penetration testing, security monitoring systems (SIEM), backup strategies, and incident response plans should be implemented. Zero Trust architecture and secure coding practices are also critical.

How is security ensured for web applications?

For web application security, HTTPS usage, input validation, SQL injection and XSS protection, CSRF tokens, rate limiting, secure session management, regular security scans, and closing OWASP Top 10 vulnerabilities are required. Secure coding standards and regular security audits should be performed.

What is Zero Trust architecture and why is it important?

Zero Trust architecture is a security model based on the principle of "trust no one, verify everything." All users and devices, whether inside or outside the network, are continuously verified. This approach provides protection against insider threats and is ideal for modern hybrid work environments. In 2025, Zero Trust has become the cornerstone of cybersecurity.

How often should penetration testing be performed?

Penetration testing should be performed at least once a year. However, for critical systems, it should be done two or three times a year, after important updates, and before new systems are put into operation. It provides the most effective results when used together with continuous security monitoring.

What should be done for GDPR and compliance?

For GDPR and compliance, data inventory should be created, data processing activities should be recorded, privacy policies should be updated, data breach notification procedures should be prepared, data protection impact assessment (DPIA) should be performed, and regular compliance audits should be conducted. Data security should be ensured with technical and administrative measures.
