Network ForensicsIn network forensics, understanding the data flow, connections, and interactions within a network is essential. Here’s an overview of important network forensics components like DNS logs, passive DNS, NetFlow, and sampling rate.DNS Logs / Passive DNSDNS LogsPurpose: DNS logs capture details about DNS queries and responses, helping trace domain name resolutions back to specific t..

Evidence Volatility (network vs memory vs disk)Evidence volatility in digital forensics refers to how quickly certain types of evidence can be lost or altered. Understanding evidence volatility is crucial because it helps prioritize what to capture first during an investigation. Here’s a breakdown of volatility in the context of network, memory, and disk evidence:Network EvidenceVolatility: High..

Three Ways to Attack - Social, Physical, NetworkIn cybersecurity, exploits are actions or tools that attackers use to compromise systems. Attacks can generally be grouped into three categories based on the method of exploitation: social, physical, and network attacks. Each type uses different tactics to bypass security, obtain access, or gather sensitive information. Here’s a breakdown of each a..
