Cybersecurity & R&D Technical Glossary
An authoritative reference guide to critical concepts in digital forensics, offensive security, regulatory compliance, and autonomous defense architectures engineered by VayuX Systems.
Incident Response
Digital Forensics and Incident Response
DFIR is a specialized cybersecurity discipline focused on investigating, containing, and remediating security breaches while preserving digital evidence according to legal chain-of-custody standards.
Indicators of Compromise
Forensic digital artifacts that serve as technical evidence that a computer network or system has been breached or infected.
Ransomware Incident Response
A specialized DFIR protocol to contain active encryption, isolate compromised systems, decrypt affected data, and prevent extortion exfiltration.
Offensive Security
Vulnerability Assessment and Penetration Testing
VAPT combines automated scanning (vulnerability assessment) with manual exploitation simulations (penetration testing) to identify and prove exploitable weaknesses in IT systems.
OWASP Top 10 Security Risks
A globally recognized standard consensus document outlining the ten most critical security risks facing modern web applications and APIs.
Red Teaming vs Penetration Testing
Penetration testing finds as many technical vulnerabilities as possible; Red Teaming simulates a multi-layered, goal-oriented adversary testing the organization’s overall defensive posture.
Operations
Security Operations Center
A SOC is a centralized organizational unit responsible for continuously monitoring, detecting, analyzing, and responding to cybersecurity events across enterprise digital assets 24/7/365.
Threat Hunting Telemetry
The proactive, hypothesis-driven examination of rich network, endpoint, and identity data to detect stealthy adversaries who have bypassed automated controls.
Compliance & Governance
Governance, Risk, and Compliance
GRC is an integrated strategy to manage an enterprise’s cybersecurity governance, address business risks, and ensure adherence to statutory and industry regulations.
Digital Personal Data Protection Act 2023
The DPDP Act 2023 is India’s principal data privacy law regulating the processing of digital personal data and mandating stringent security safeguards.
CERT-In Cyber Security Directions
Binding cybersecurity directives issued by the Indian Computer Emergency Response Team (CERT-In) mandating strict logging and 6-hour breach reporting.
Architecture & R&D
MITRE ATT&CK Framework
MITRE ATT&CK is a globally accessible, curated knowledge base of adversary tactics, techniques, and procedures (TTPs) based on real-world observations.
Zero Trust Network Architecture
Zero Trust is a security paradigm rooted in the principle "never trust, always verify," requiring strict identity and device validation for every access request.
Post-Quantum Cryptography
Cryptographic algorithms engineered to remain secure against decryption attacks by future cryptanalytically relevant quantum computers.
Heuristic Threat Detection
An advanced detection methodology that identifies unknown malware and zero-day threats by analyzing behavioral characteristics rather than static signatures.
