📡 BroadcastDetector: Advanced Detection for 🛰️ Switch & Network Loops, ARP Spoofing Attacks, Loop Protection & Broadcast Traffic Analysis 🖥️

In modern IT infrastructures, issues such as switch loops, network loops and ARP spoofing attacks can cripple entire systems. A misconfigured switch, faulty loop protection or malicious ARP spoofing can lead to excessive network broadcast traffic and deteriorate performance.

BroadcastDetector is a powerful, automated tool that detects and analyzes switch loops, network loops, ARP spoofing attacks, loop protection issues, and abnormal broadcast activities in real-time.

Why is Loop Protection So Important?

When a switch loop occurs, packets circulate continuously, consuming bandwidth and processing power. Without proper loop protection, these network loops can result in slowdowns, packet losses, or complete outages.

Additionally, uncontrolled ARP spoofing attacks or a network broadcast storm can flood devices with unnecessary traffic, causing bottlenecks and conflicts.

BroadcastDetector helps IT professionals and network administrators quickly detect these issues and take preventative measures.

Key Features of BroadcastDetector

How Does BroadcastDetector Work?

  • Captures network broadcast traffic using tcpdump and analyzes it with pyshark.
  • Identifies patterns related to switch loops, network loops, and abnormal network broadcast activity.
  • Analyzes ARP traffic patterns to identify and prevent ARP spoofing attacks.
  • Performs comprehensive Broadcast Traffic Analysis to optimize network performance.
  • Stores relevant data such as MAC addresses, VLAN IDs, and timestamps.
  • Sends real-time notifications to inform administrators of detected issues.
  • Helps maintain network stability by preventing slowdowns and outages.
  • To scan additional VLANs besides the untagged VLAN, the switch port where the BroadcastDetector is connected must be configured as a trunk port with the desired VLANs tagged.
