PCAP: Packet Capture in Cybersecurity
PCAP stands for Packet Capture. PCAP is the process of intercepting and recording raw network packets for later analysis. PCAP files contain complete packet headers and payloads, giving analysts full visibility into network communications.
How PCAP Is Used in Cybersecurity
Incident responders analyze PCAP files to reconstruct attack sequences and extract transferred files or credentials. SOC analysts use PCAP data to verify whether an alert represents a true positive by examining the actual traffic. Penetration testers capture packets during engagements to demonstrate data exposure risks.
