Cyber Terminologies and Fundamentals

Definitions 

Hashing

A cryptographic process that transforms input data into a fixed-length value to ensure data integrity.

Honeypot

A security mechanism designed to attract and analyze cyber threats by simulating real systems.

Hacking-as-a-Service (HaaS)

A criminal business model where hacking tools and services are sold or rented.

Host-Based Intrusion Detection System (HIDS)

A security system that monitors individual devices for suspicious activity.

Hardware Security Module (HSM)

A dedicated hardware device used to manage cryptographic keys securely.

Human Factor in Security

The role of human behavior in cybersecurity risks and mitigation strategies.

Hidden Malware

Malicious software that conceals its presence to avoid detection by security tools.

Homomorphic Encryption

An encryption method that allows computations to be performed on encrypted data without decryption.

HMAC Authentication

A cryptographic technique used to verify the integrity and authenticity of messages.

Heap Spray Attack

An attack that exploits memory vulnerabilities to execute arbitrary code.

Heuristic Analysis

A security technique that detects unknown threats by analyzing behavioral patterns.

Hijacking

An attack where an attacker takes control of a session, account, or network communication.

HTTP Security Headers

HTTP response headers that provide security enhancements against various web attacks.

Host Isolation

A cybersecurity measure that isolates infected or compromised systems from the network.

HSTS Bypass

A technique used to bypass HTTP Strict Transport Security (HSTS) protections.

Hardcoded Secrets

Sensitive data, such as API keys and passwords, embedded directly in source code.

Hypervisor Security

Security measures to protect virtual machine hypervisors from exploits and unauthorized access.

Hexadecimal Obfuscation

A technique that conceals malicious code using hexadecimal encoding to evade detection.

Hybrid Encryption

A cryptographic method that combines symmetric and asymmetric encryption for secure communication.

High-Privilege Account Security

Best practices to secure privileged user accounts against unauthorized access.
