Study Notes
Cloud Security Concerns
- Data Breaches: Cloud service providers hold customer data, which can be leaked or stolen if not stored appropriately (e.g., encryption, geographical boundary compliance).
- Lack of Control: Reliance on service providers for security can lead to a handoff of control regarding security.
Authentication and Authorization
- Hacked Accounts: Unauthorized access to cloud services can occur through compromised user accounts (e.g., phishing, social engineering).
- Insider Threats: Authorized users with malicious intent can compromise the system.
- Multifactor Authentication: Essential to ensure authorized and authenticated users access cloud services.
Malware and Virus Protection
- Malware Infections: Malware can compromise end-user computers and infrastructure as a service (IaaS) in the cloud.
- Precautions: Run software on computers, use Host-based Intrusion Prevention System (HIPS) or antivirus software, and implement next-generation firewalls with SSL/TLS decryption.
API Security
- Weak APIs: Insecure or weak Application Programming Interfaces (APIs) can lead to configuration changes or further access.
- API Authentication: Essential to ensure secure authentication when controllers interact with devices using APIs.
Distributed Denial of Service (DDoS) Attacks
- Botnets: Army of infected computers can launch DDoS attacks, overwhelming cloud services, and rendering them unavailable.
- Service Provider Protection: Cloud service providers should have countermeasures to defend against DDoS attacks.
Backups and Recovery
- Importance of Backups: Regular backups ensure data recovery in case of disasters or data loss.
- Restore Point Objective (RPO): Determine the desired restore point to minimize data loss.
- Backup Validation: Test and validate backup capabilities to ensure data can be restored when needed.
Isolation and Segmentation
- Multi-Tenancy: Ensure service providers implement proper isolation and segmentation between customers to prevent access and impact on other customers' resources.
