File Encryption

File encryption is a security technique used to protect the confidentiality and integrity of data stored in files or folders. It involves the process of converting plaintext data into ciphertext using cryptographic algorithms and keys, making it unreadable and unintelligible to unauthorized users. Only users with the appropriate decryption key or password can decrypt and

Fileless Attack

A fileless attack, also known as a fileless malware attack or memory-based attack, is a type of cyber attack that does not rely on traditional malware files being stored on the victim’s system. Instead, fileless attacks leverage legitimate system tools, processes, or vulnerabilities to execute malicious code directly in the system’s memory, making them difficult

Fileless Malware

Fileless malware, also known as memory-based malware or non-malware attacks, refers to a type of malicious software that operates without leaving traditional traces on the file system of the infected host. Unlike traditional malware, which typically relies on executable files or scripts stored on disk, fileless malware resides and executes directly in the computer’s memory

Firewall

A firewall is a network security device or software application that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet, to prevent unauthorized access, data breaches, or malicious activities. Firewalls can be implemented

Forensic Analysis

Forensic analysis, also known as digital forensics, is the process of examining digital evidence, such as computer systems, storage devices, networks, and electronic data, to investigate and analyze security incidents, cybercrimes, legal disputes, or regulatory violations. Forensic analysis aims to gather, preserve, analyze, and present digital evidence in a legally admissible manner to support investigations,
