The Role of Digital Forensics in Modern Cybersecurity
Digital Forensics and Incident Response (DFIR) is the science of uncovering digital artifacts, preserving evidentiary integrity, and reconstructing cybersecurity incidents to determine how a breach occurred.
Key Forensic Investigation Disciplines:
**Live Memory Forensics (RAM)**: Using Volatility 3 and LiME to extract encryption keys, unencrypted passwords, running malware injected processes, and active network connections.**Disk & Storage Forensics**: Bit-stream forensic imaging using write blockers (FTK Imager, EnCase, dd/dc3dd) maintaining cryptographic SHA-256 / MD5 hashes for chain of custody.**Mobile Device Forensics**: Physical, logical, and file-system extraction of iOS and Android devices, uncovering deleted chats, call logs, geolocation, and app data.**Network & Log Forensics**: Reconstructing packet captures (PCAP) and analyzing Windows Event Logs (Sysmon), Linux audit logs, and firewall traffic.**Ransomware Triage**: Reverse engineering ransomware executables to identify the threat actor group, ransom notes, and decryption possibilities.Court Admissibility & Legal Compliance:
Forensic investigators must adhere strictly to legal protocols (Section 65B of the Indian Evidence Act / IT Act 2000) ensuring that digital evidence is valid and admissible in a court of law.
