PACKET FILTER APPROACH TO DETECT DENIAL OF SERVICE ATTACKS
… floods a target system with a high quantity of packets or connections to crash its network resources, bandwidth, equipment, or servers. Packet filtering methods are the most known way to prevent these attacks via identifying and blocking the spoofed attack from reaching its target. In this …

Packet filter performance monitor (anti-DDOS algorithm for hybrid topologies)
… by flooding the hardware firewall with HTTP packets until the firewall became overwhelmed and unresponsive. The second part implements the same test as the first, but targeted towards the virtual firewall. The same parameters, test factors, and determinants were used; however a different load …

EKFuzz: Fuzzing the BPF subsystem
The extended Berkeley Packet Filter (eBPF) framework has revolutionized the way developers interact with the Linux kernel by enabling safe, dynamic programmability. However, this flexibility comes at a cost. The new kernel functions (kfuncs) exposed to eBPF programs are rapidly proliferating, often …

Vessel : a lightweight container for network analysis
… tests. Vessel leverages the Extended Berkeley Packet Filter and Linux network namespaces. We demonstrate the utility of the tool by analyzing TCP flows associated with competing web-based speed measurement tests

A methodology for using eBPF to efficiently monitor network behavior in Linux Kubernetes clusters
… to the platform level. The extended Berkeley Packet Filter (eBPF) can enable high performance and low overhead collection for platform level monitoring. Existing commercial eBPF monitoring systems are often tightly integrated systems with large dependencies and little flexibility in …

Preventing Unintended Data Access: Information Flow Control in eBPF
The extended Berkeley Packet Filter (eBPF) technology has become widely adopted by enterprises due to its flexibility and ability to enhance tracing, observability, monitoring, and security within the kernel. However, since the kernel is a critical resource containing sensitive information, eBPF …

On the implications of unsafe eBPF composition
In the era of Linux being omnipresent, the demand for dynamically extending kernel capabil- ities without requiring changes to kernel source code or loading kernel modules at runtime is increasing. This is driven by numerous use cases such as observability, security, and network- ing, which can be …

Softwarový model firewallu
Tato bakalářská práce se zabývá problematikou bezestavových paketových filtrů a algoritmů klasifikace paketů. Hlavním úkolem je vytvořit softwarovou implementaci firewallu a změřit rychlost klasifikace paketů. Implementovaný klasifikátor využívá pro klasifikaci algoritmus Perfect-Hash. Klasifikátor …
