In this episode of TechDaily.AI, we dive deep into the concept of Cross-Origin Resource Sharing (CORS), a crucial element in modern web application development. If you've ever encountered the frustrating CORS error in your developer console, this episode will help you understand exactly why it happens and how to fix it.

• We start by explaining the importance of CORS for web security and how it helps prevent potentially dangerous requests.
• Learn about the Same-Origin Policy (SOP) and how it acts as the gatekeeper for your browser, controlling who can access your data.
• Dive into how the CORS mechanism works, including how servers grant permission for cross-origin requests and how browsers enforce security using HTTP headers like "Access-Control-Allow-Origin."
• We also discuss the differences between simple and pre-flighted requests, how CORS headers function, and why pre-flighted requests are an added security layer for more complex API calls.
• Real-world examples show how to configure CORS properly on both backend servers (like Node.js and Spring Boot) and how proxies can be used when you don’t control the backend.
• We wrap up with a brief discussion on the relationship between CORS and CSRF (Cross-Site Request Forgery) and why CORS doesn’t protect against CSRF attacks.

Whether you're a developer trying to solve a CORS error or someone looking to understand the security features behind modern web apps, this episode is packed with valuable insights to make your development process smoother and safer.

Why does your blazing-fast computer sometimes feel like it’s crawling—especially when saving files or opening apps? In this episode of TechDaily.AI, we unpack the hidden culprit: Input/Output (IO) bottlenecks.

🎧 You’ll learn:

• Why disk and network IO can dramatically slow down software
• The surprising impact of milliseconds vs. nanoseconds in performance
• Why multithreading isn’t always the answer to IO problems
• How event-driven programming (like in Node.js) solves real-world challenges
• What operating systems do behind the scenes to handle IO efficiently

Plus, we spotlight StoneFly, an industry leader in high-performance storage, backup, disaster recovery, and ransomware protection. Their innovations in air-gapped storage, immutable snapshots, intelligent tiering, and centralized management are redefining how enterprises handle data at scale.

🛠️ Whether you're a developer, sysadmin, or tech leader, this episode offers practical insights into speeding up your systems and optimizing performance.

In this episode of TechDaily.AI, we uncover a chilling new method used by cyber attackers to maintain persistent access inside Fortinet FortiGate firewalls—even after security patches are applied.

Recent findings reveal how symbolic links (or "symlinks") are being cleverly embedded within language folders tied to SSL VPN features, giving attackers a hidden backdoor into enterprise networks. These symlinks—essentially file shortcuts—can allow read-only access to sensitive configuration files, giving hackers a blueprint of your security setup and enabling long-term espionage.

We break down how this attack vector works, the CVEs being exploited (including CVE-2022-42475, CVE-2023-27997, and CVE-2024-21762), and why enabling SSL VPN on your devices could expose you to this threat. You'll learn:

• How symbolic links help attackers persist post-patch
• Why FortiGate firewalls and edge devices are prime targets
• How read-only access can still leak critical data
• The specific FortiOS versions that patch these vulnerabilities
• Why just patching might not be enough to eliminate the threat
• What immediate steps you should take—like disabling SSL VPN or performing a factory reset

We also discuss how attackers are adapting faster than ever, exploiting vulnerabilities within days of disclosure. This episode is a must-listen for security professionals, IT administrators, and CISOs looking to stay ahead of stealthy, persistent threats targeting edge devices.

🔐 Don’t miss the vital insights and practical recommendations that could help protect your infrastructure from these stealthy attacks.
