Possible disadvantages of tcpdump

• Steep learning curve
  For users unfamiliar with command-line interfaces and packet-level networking, tcpdump can be difficult to learn due to its complex commands and options.
• Minimal graphical interface
  tcpdump lacks a graphical user interface (GUI), which can make it less accessible for users who prefer visual tools over text-based interfaces.
• Limited analysis capability
  While tcpdump is excellent for capturing packets, it offers limited built-in analysis features, requiring additional tools for comprehensive analysis of captured data.
• High resource usage
  Running tcpdump with extensive capture options or on high-traffic networks can result in significant CPU and memory usage, potentially impacting system performance.
• Security risks
  tcpdump requires root or elevated privileges to capture packets, which could pose security risks if not managed correctly, especially on sensitive systems.
