Azure 101: Shared responsibility in the Azure Cloud

Baixar para ler offline

Whether you’re working exclusively on Azure or with multiple cloud environments, there are certain things you should consider when moving assets to the public cloud. As with any cloud deployment, security is a top priority, and moving your workloads to the Azure cloud doesn’t mean you’re not responsible for the security of your operating system, applications, and data.

Building on the security of the Azure infrastructure, this shared security responsibility starts with making sure your environment is secure. In this session, we will discuss step-by-step what you need to do to secure access at the administrative, application and network layers.

  9. 9. SECURITY BEST PRACTICES
  10. 10. 10 Best Practices for Security 1. Understand the Cloud Providers Shared Responsibility Model 2. Secure your code 3. Create access management policies 4. Data Classification 5. Adopt a patch management approach 6. Review logs regularly 7. Build a security toolkit 8. Stay informed of the latest vulnerabilities that may affect you 9. Understand your cloud service providers security model 10. Know your adversaries
  11. 11. 1. Understand the Cloud Providers Shared Responsibility Model The first step to securing cloud workloads is understanding the shared responsibility model Microsoft will secure most of the underlying infrastructure, including the physical access to the datacenters, the servers and hypervisors, and parts of the networking infrastructure…but the customer is responsible for the rest. Taken from the Shared Responsibility for Cloud Computing whitepaper, published by Microsoft in March 2016
  12. 12. 2. 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 • DevSecOps
  13. 13. 3. Create Secure Access Management Policies • Simplify access controls (KISS) • Lock down Admin account in Azure • Enable MFA (Azure, hardware/software token) • Identify data infrastructure that requires access (*Lock down AzureSQL) • Define roles and responsibilities (delegating service admins) • Azure NSG (private vs public) • Continually audit access (Azure Audit Logs) • Start with a least privilege access model (RBAC) *avoid owner role unless absolutely necessary • Don’t store keys in code (e.g. secret keys) • AAD Premium – (*Security analytics and alerting)
  14. 14. 4. 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
  15. 15. 5. Adopt a Patch Management Approach • Use trusted images (*Prevent users from launching untrusted images) • Constantly scan all vulnerabilities in your images and patch them • 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
  16. 16. 6. Log Management Strategy • Monitoring for malicious activity • Forensic investigations • Compliance needs • System performance • All sources of log data is collected and retained • Data types (Windows, Syslog) • Azure AD behavior • Azure Audit Logs (services, instances…activity, powershell) • Azure SQL Logs • Azure App Services Logs • Review process • Live monitoring • Correlation logic
  17. 17. 7. Build a Security Toolkit • Recommended Security Solutions • Antivirus • IP tables/Firewall • Backups • FIM • Intrusion Detection System (VNET ingress/egress) • Malware Detection • Web Application Firewalls (inspection at Layer 7) • Forensic Image of hardware remotely • Future Deep Packet Forensics • Web Filters • Mail Filters • Encryption Solutions • Proxies • Log collection • SIEM Monitoring and Escalation • Penetration Testing
  18. 18. 8. Stay Informed of the Latest Vulnerabilities • Websites to follow • http://www.securityfocus.com • http://www.exploit-db.com • http://seclists.org/fulldisclosure/ • http://www.securitybloggersnetwork.com/ • http://cve.mitre.org/ • http://nvd.nist.gov/ • https://www.alertlogic.com/weekly-threat-report/
  19. 19. 9. Understand Your Service Providers Security Model • Understand the security offerings from your provider • Probe into the Security vendors to find their prime service • Hypervisor exploits are patched by the service provider • Questions to use when evaluating cloud service providers
  20. 20. 10. Understand your Adversaries
  21. 21. Threats are 24x7 = Security Operations 24x7 Monitor intrusion detection and vulnerability scan activity Search for Industry trends and deliver intelligence on lost or stolen data Collect data from OSINT and Underground Sources to deliver Intelligence and Content Identify and implement required policy changes Escalate incidents and provide guidance to the response team to quickly mitigate Incidents Monitor for Zero-Day and New and Emerging attacks Cross product correlate data sources to find anomalies

  31. 31. Alert Logic solutions are easy to deploy • Use a combination of host based agents and appliances to collect network and application traffic • Agents also collect logs from the VM • Azure Activity Logs are collected via the Azure Monitor API • Azure SQL or App Services Logs are collected from Azure storage accounts • Appliances can be used to do internal scanning, or we can do external and PCI scanning from our cloud
