What are the Key Components of Multi-Layer Security?
Multi-layer security involves several components working together to provide comprehensive protection. These include:
- Encryption: Encrypting emails and data ensures that only authorized recipients can access the content. - Authentication: Techniques like SPF, DKIM, and DMARC verify the sender’s identity, reducing the risk of phishing. - Anti-Virus and Anti-Malware: Scanning emails for malicious software prevents infections and protects the network. - Firewalls: These act as barriers against unauthorized access, monitoring and controlling incoming and outgoing traffic. - User Education: Training employees on email security best practices minimizes human error and enhances overall security.
