Introduction

Ransomware attacks continue to be one of the most pressing threats in cybersecurity, with attackers increasingly targeting organizations of all sizes and industries. These malicious attacks encrypt critical data and demand payment for the decryption key. In response to this growing threat, implementing effective defensive strategies is essential for minimizing risks and ensuring that organizations can quickly recover from an attack. This course will focus on preventive, detective, and responsive measures to protect against ransomware attacks, helping organizations fortify their defenses.

Prerequisites

• Basic knowledge of cybersecurity principles.
• Understanding of network security, data protection, and IT infrastructure.
• Familiarity with common ransomware attack vectors.
• Experience with security tools and technologies is helpful but not required.
