Study Notes
tcpdump Functionality
- Captures packets from network traffic for analysis.
- Provides a textual analysis of the captured packets.
Differences Between tcpdump and Wireshark
- Wireshark has a graphical interface, enhancing user interaction and ease of use.
- Wireshark understands a wider array of application-level protocols compared to tcpdump.
Considerations for IDS Installation Design
- Traffic bandwidth must be assessed to ensure the IDS can process the expected volume of network data.
- Sufficient storage capacity is crucial for retaining logs and captured packets over time.
IDS vs. IPS
- An Intrusion Detection System (IDS) detects and alerts on intrusions but does not take action to block them.
- An Intrusion Prevention System (IPS) actively blocks detected threats by modifying firewall rules.
Limitations on Packet Capture
- Network interface cards (NICs) must be in promiscuous or monitor mode to capture all traffic; otherwise, they only capture packets directly addressed to them.
- Access limitations may arise from network architecture, such as being connected to a switch that prevents capturing traffic from other devices.
