Ransomware Protection

Introduction

Ransomware is a type of malicious software that encrypts a victim's files, making them inaccessible until a ransom is paid. This lesson will explore advanced strategies to protect against ransomware attacks.

Key Definitions

• Ransomware: Malware that locks or encrypts files, demanding payment for access.
• Phishing: A method of tricking users into revealing sensitive information.
• Backup: The process of copying data to prevent loss.

Protection Strategies

1. Regularly update software and systems to patch vulnerabilities.
2. Implement a robust backup solution:

   
   # Example of a simple backup script in Python
   import shutil
   import os
   
   def backup_files(source_dir, backup_dir):
       if not os.path.exists(backup_dir):
           os.makedirs(backup_dir)
       shutil.copytree(source_dir, backup_dir)
       print("Backup completed successfully.")
   
   backup_files('/path/to/source', '/path/to/backup')
                   

3. Utilize advanced security software with ransomware protection features.
4. Educate employees on identifying phishing attempts and secure practices.

Best Practices

• Use strong, unique passwords for all accounts.
• Enable two-factor authentication wherever possible.
• Restrict user permissions to the minimum necessary.
• Conduct regular security audits.
• Keep your antivirus and anti-malware software updated.
