Business Logic Attacks

In this episode of Ehsan’s Tech Lounge, we dive into a silent but very serious threat:
Business Logic Attacks — attacks that do not rely on code injection, but instead exploit the order of requests
(user journey) and the logic of the application. These attacks often stay invisible to traditional firewalls
and security tools.
What you’ll learn in this video:
• The difference between a traditional WAF and the need for modern API Security solutions
• Three real, relatable scenarios: coupon abuse, ATO (Account Takeover), and race conditions in fintech
• How API inventory, distributed tracing, and behavior baselining help uncover logic-based attacks
• A practical playbook for detection, rapid response, and remediation — actionable steps that DevOps and SecOps teams should start implementing today

QUIC: Performance Revolution or Security Blind Spot?

In the fourth episode of Ehsan’s Tech Lounge Podcast, we explore how HTTP/3 powered by QUIC promises blazing-fast
connections and a better user experience — but also introduces new visibility and inspection challenges for security
vendors. We trace the evolution of HTTP protocols, unpack the architectural benefits of QUIC, and ask the critical
question: Can our firewalls keep up? Join us as we analyze how vendors are tackling decryption, telemetry, and
detection inside encrypted QUIC traffic.
