SECURITY BEST PRACTICES

10 Best Practices of Cloud Security

1.  Secure your code 2.  Create access management policies 3.  Data Classification 4.  Adopt a patch management approach 5.  Review logs regularly 6.  Build a security toolkit 7.  Stay informed of the latest vulnerabilities that may affect you 8.  Understand your cloud service providers security model 9.  Understand the shared security responsibility 10. Know your adversaries

1. Secure Your Code

• Test inputs that are open to the Internet • Add delays to your code to confuse bots • Use encryption when you can • Test libraries • Scan plugins • Scan your code after every update • Limit privileges • Stay informed

2. Create Access Management Policies

•  Identify data infrastructure that requires access • Define roles and responsibilities • Simplify access controls (KISS) • Continually audit access • Start with a least privilege access model

3. Data Classification

•  Identify data repositories and mobile backups •  Identify classification levels and requirements • Analyze data to determine classification • Build Access Management policy around classification • Monitor file modifications and users

4. Adopt a Patch Management Approach

•  Inventory all production systems • Devise a plan for standardization, if possible • Compare reported vulnerabilities to production infrastructure • Classify the risk based on vulnerability and likelihood • Test patches before you release into production • Setup a regular patching schedule • Keep informed, follow bugtraqer • Follow a SDLC

5. Importance of Log Management and Review

• Monitoring for malicious activity • Forensic investigations • Compliance needs • System performance

• All sources of log data is collected • Data types (Windows, Syslog) • Review process •  Live monitoring • Correlation logic

6. Build a Security Toolkit • Recommended Security Solutions

•  Antivirus •  IP tables/Firewall •  Backups •  FIM •  Intrusion Detection System •  Malware Detection •  Web Application Firewalls •  Forensic Image of hardware remotely •  Future Deep Packet Forensics •  Web Filters •  Mail Filters •  Encryption Solutions •  Proxies •  Log collection •  SIEM Monitoring and Escalation •  Penetration Testing

7. Stay Informed of the Latest Vulnerabilities

8. Understand Your Service Providers Security Model • Understand the security offerings from your provider • Probe into the Security vendors to find their prime service • Hypervisor Example • Questions to use when evaluating cloud service providers

9. Service Provider & Customer Responsibility Summary
