Packet Capture (PCAP):

• Mechanism: Packet capture involves intercepting and storing data packets as they travel across a network. 
• Purpose: It enables detailed analysis of network traffic, helping to detect malicious activity, identify vulnerabilities, and troubleshoot network problems. 
• Tools: This can be performed using dedicated hardware, software, or network devices. 
• Benefits: It provides a comprehensive view of network traffic, allowing for the identification of suspicious patterns and anomalies that may indicate a security threat. 
• Forensic Analysis: Captured packets can serve as vital forensic evidence during investigations of security incidents. 

Capture the Flag (CTF):

• Definition: A cybersecurity competition where participants challenge each other to find and exploit vulnerabilities in systems to capture a hidden piece of information (the “flag”). 
• Purpose: CTF exercises are designed to enhance cybersecurity skills, test incident response readiness, and provide a fun and engaging way to learn about cybersecurity threats. 
• Types: CTFs can be Jeopardy-style, where participants solve challenges, or attack-defense style, where participants actively defend a system from attacks. 
• Benefits: CTFs help organizations evaluate their security posture, identify vulnerabilities, and improve their ability to respond to security incidents
