Tracking Multiple Requests Over a Single Connection with eBPF
Why capturing HTTP Traffic is Crucial for Network Security? Capturing HTTP traffic is like having a digital security camera at your network’s entrance, and it’s essential for keeping your network safe. This ‘camera’ helps you monitor who’s accessing your online space, allowing you to detect and prevent potential security threats, such as cyberattacks and unauthorized…

Capturing Multiple Requests on the Same Connection with eBPF
To incorporate the keywords like "HTTP 403," "HTTP error 503," "the service is unavailable," and "monitor Google Cloud API traffic" into the blog, I would recommend integrating them naturally into the content. Additionally, for internal linking from Keploy.io’s website blogs, here’s a possible update to your blog, integrating the mentioned keywords and linking: Why Capturing…

Executing EBPF in Github Actions
At Keploy, we wanted our tool to be part of the Github pipeline so that developers could be guaranteed that modifications made in pull requests could be safely merged and deployed. The only problem we had was ~ is it possible. The reason for this question is because Keploy uses eBPF to track network calls,…

eBPF for TLS Traffic Tracing: Secure & Efficient Observability
Tracing TLS (Transport Layer Security) traffic is crucial for modern observability systems. It helps monitor encrypted communication, diagnose issues, and optimize application performance. However, traditional methods like TLS proxying and packet capturing often come with significant performance overheads and security risks. They are not always the ideal solution, particularly for high-performance or security-sensitive environments. This…

BitBucket Self-Hosting : Running ebpf/Privileged programs
Bitbucket is a robust tool for source code management and continuous integration/continuous deployment (CI/CD). It offers flexibility in setting up pipelines, but there are limitations, particularly around root privileges and mounting volumes. This blog explores these limitations and provides detailed solutions using Docker-in-Docker (DinD) and Linux shell scripts. What is Bitbucket? Bitbucket is a Git…

eBPF, Service Mesh and Sidecar
The operating system is like the boss of your computer, handling security, networking, and keeping an eye on what’s happening. But tweaking or improving the core part of the operating system, called the kernel, is a bit tricky because it’s mainly focused on keeping things stable and secure. Most cool new stuff usually happens outside…

Decoding HTTP/2 Traffic is Hard, but eBPF can help
I’ve come across a particular challenge that many of us face: decoding HTTP/2 traffic. In this blog, I’ll share insights on why decoding HTTP/2 headers can be tricky, how HPACK adds a layer of complexity, and most importantly, how eBPF uprobes can come to the rescue. It is crucial to gain visibility into the messages…
