Best Practices for Security
• Understand the Cloud Providers Shared Responsibility Model
• Azure Network Security Best Practices
• Data Security and Access Management
• Secure your code
• Data Classification
• Adopt a patch management approach
• Review logs regularly
• Stay informed of the latest vulnerabilities that may affect you
• Know your adversaries

7.
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

8.
Azure Network Security Best Practices
• Logically segment subnets
• Control routing behavior
• Enable Forced Tunneling (e.g. forcing internet through on-
premise and/or DC)
• Use Virtual network appliances (e.g FW, IDS/IPS, AV, Web
Filtering, Application ELB)
• Deploy DMZs for security zoning
• Optimize uptime and performance
• Use global load balancing
• Disable RDP or SSH Access to Azure Virtual Machines
• Enable Azure Security Center
• Extend your datacenter into Azure

9.
Data Security and Access Management
• Lock down Admin account in Azure
• Enable MFA (Azure, hardware/software token)
• Start with a least privilege access model (e.g. Use
RBAC) *avoid owner role unless absolutely necessary
• Identify data infrastructure that requires access (e.g.
Lock down AzureSQL)
• Azure NSG (private vs public)
• Continually audit access (Azure Activity Logs)
• AAD Premium – (*Security analytics and alerting)
• Manage with Secure Workstations (e.g. DMZ, MGMT)
• Protect data in transit and at rest
• Encrypt Azure Virtual Machines
• Enable SQL Data Encryption

10.
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
• Don’t store keys in code (e.g. secret keys)
• DevSecOps – Develop Security as Code

11.
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

12.
Adopt a Patch Management Approach
• Use trusted 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
• Stay informed with the latest vulnerabilities
• Follow an SDLC lifecycle

13.
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, Flat Files)
• Azure AD behavior
• Azure Activity (services, instances…activity,
powershell)
• Azure SQL Logs
• Azure App Services Logs (e.g. IIS)
• Review process
• Live monitoring
• Correlation logic

Vulnerabilities
+ Change
+ Shortage
Complexity of defending web applications and workloads
Risks are moving up the stack
1. Wide range of attacks at every
layer of the stack
2. Rapidly changing codebase can
introduces unknown vulnerabilities
3. Long tail of exposures inherited
from 3rd party development tools
4. Extreme shortage of cloud and
application security expertise
