• Use secure protocols for data transmission
• Implement data loss prevention (DLP) measures

C. Problem 3: DDoS Attacks and Service Disruptions

Solution: Implementing DDoS Protection Measures and Redundancy

To mitigate the impact of DDoS attacks and service disruptions, organizations should:

• Deploy DDoS protection services
• Use content delivery networks (CDNs) for load balancing
• Implement redundant infrastructure and failover mechanisms

D. Problem 4: Misconfigurations and Vulnerabilities

Solution: Regular Security Audits and Patch Management

To address misconfigurations and vulnerabilities, organizations should:

• Conduct regular security audits and vulnerability assessments
• Keep software and systems up to date with the latest patches
• Implement configuration management tools
