What does IDS stand for in network security?

IDS stands for Intrusion Detection System, which monitors network traffic for suspicious activities or potential security breaches.

How is an IPS different from an IDS?

IPS (Intrusion Prevention System) not only detects but also actively blocks threats, whereas IDS (Intrusion Detection System) only monitors and alerts security teams about suspicious activities.

What is a VPN in cybersecurity?

VPN (Virtual Private Network) is a secure tunnel that encrypts internet traffic to ensure privacy and security, often used for secure remote access.

What does NAC stand for?

NAC (Network Access Control) is a security solution that restricts unauthorized devices from accessing a network.

What is RSA encryption used for?

RSA (Rivest-Shamir-Adleman) encryption is used for securing data transmissions, such as online banking transactions and email encryption.

What does AES stand for, and why is it important?

AES (Advanced Encryption Standard) is a widely used encryption algorithm that protects sensitive data in various applications, including cloud storage and secure communications.

What is SHA in cybersecurity?

SHA (Secure Hash Algorithm) is a cryptographic hash function used to verify data integrity in digital signatures and certificates.

How does HMAC improve API security?

HMAC (Hash-based Message Authentication Code) is used to verify message integrity in APIs by combining a secret key with a hash function.

What is a MITM attack?

MITM (Man-in-the-Middle) attack occurs when an attacker intercepts communication between two parties to steal or alter data.

How does an SQLi attack work?

SQLi (SQL Injection) is a hacking technique where attackers manipulate database queries to gain unauthorized access to sensitive data.

What is a DDoS attack?

DDoS (Distributed Denial-of-Service) is an attack that overwhelms a target system with excessive traffic, making it inaccessible to users.

What is XSS in cybersecurity?

XSS (Cross-Site Scripting) is an attack where hackers inject malicious scripts into a web application to compromise user data.

What does IAM stand for?

IAM (Identity and Access Management) is a framework for controlling user access to digital resources in cloud environments.

What is CASB in cloud security?

CASB (Cloud Access Security Broker) ensures security policies are enforced between cloud service providers and users.

What does ZTNA mean?

ZTNA (Zero Trust Network Access) is a security model that requires user verification before granting access to cloud applications.

How does SASE improve remote work security?

SASE (Secure Access Service Edge) integrates networking and security functions to protect remote users and cloud resources.

What is MFA in cybersecurity?

MFA (Multi-Factor Authentication) requires multiple verification methods, such as passwords and OTPs, to enhance security.

How does SSO work?

SSO (Single Sign-On) allows users to log into multiple applications with one set of credentials, improving convenience and security.

What is RBAC?

RBAC (Role-Based Access Control) assigns permissions based on job roles to prevent unauthorized access.

What is OAuth used for?

OAuth (Open Authorization) enables secure third-party access to user data without sharing login credentials.

What does SOC 2 compliance mean?

SOC 2 (System and Organization Controls 2) ensures cloud service providers follow strict security and privacy standards.

What is GDPR in cybersecurity?

GDPR (General Data Protection Regulation) is a data protection law that safeguards user privacy in Europe.

Why is HIPAA important for healthcare security?

HIPAA (Health Insurance Portability and Accountability Act) regulates security measures to protect patient health data.

What is PCI-DSS?

PCI-DSS (Payment Card Industry Data Security Standard) is a set of security rules that protect credit card transactions from fraud.

What is SIEM in cybersecurity?

SIEM (Security Information and Event Management) collects and analyzes security data to detect threats.

How does EDR enhance security?

EDR (Endpoint Detection and Response) detects and responds to cyber threats targeting endpoint devices.

What is the role of a SOC?

SOC (Security Operations Center) is a team that monitors and responds to cybersecurity threats in real-time.
