The document discusses identity and content security for cloud services like Office 365. It describes the evolving threat landscape where data breaches are increasingly common. It then outlines various approaches Microsoft takes to secure user identity, access to applications and content, device management, and auditing and monitoring in its cloud services. These include multi-factor authentication, conditional access policies, encryption of data in transit and at rest, activity monitoring and alerts, and mobile device management capabilities. The document aims to help organizations understand how to translate on-premises security practices to the cloud to properly secure user identity and regulate access to content.

20. Things to Consider
Known Vulnerabilities
• Enable business apps
• Block “bad” apps
• Limit app functions
• Limit file types
• Block websites
• Exploits
• Malware
Unknown Vulnerabilities
• Detect Malicious websites
• Bad domains
• Stolen credentials
• Dynamic analysis
• Static analysis
• Attack techniques
• Anomaly detection
• Analytics

21. Physical and logical isolation
Limited datacenter access
Restricted to essential personnel only
Multiple factors of authentication including smart cards and biometrics
On-premise security officers, motion sensors, video surveillance
Intrusion detection alerts include anomalous activity by datacenter engineers
Isolated network and identity
Networks are isolated from the Microsoft corporate network
Administered with dedicated Active Directory domains
No domain trust outside of the service, no domain trust between test and production
Further partitioned into isolated domains for management and security

22. Protected in transit
Encrypted between client and service
TLS 1.2 with Perfect Forward Secrecy, 2048-bit key
TLS 1.0 is minimum supported protocol
Connection will negotiate the most secure protocol supported by your client
Only secure access is permitted
SharePoint Online requires HTTPS for all authenticated connections
HSTS header prevents HTTP downgrade on untrusted networks
Encrypted within the service
Customer content is always encrypted in transit between datacenters

23. Application security
Security Development Lifecycle
All engineers receive security training annually
Code review and static analysis required for every change
Microsoft Security Response Center
Dedicated team for vulnerability report assessment and response
Skilled engineers triage reports and evaluate mitigations
Online Services Bug Bounty
Incentivizes vulnerability hunting by external researchers
Researchers receive credit and financial reward when they disclose responsibly

24. Service Encryption
Application-level encryption
Service uses per-file keys to protect SharePoint content
Microsoft manages these keys
Service automatically creates them when a file is uploaded or edited
Microsoft can transparently roll them or upgrade them as needed
Defense-in-depth
Ensures separation between server admins, Azure admins, and customer content

25. Service Encryption with Customer Key
Customer Keys Tenant Intermediate Key Site Encryption Key File Chunk Keys

26. Content security
Volume encryption
BitLocker encryption protects drives where content is stored
Renders content unreadable if drive is removed from the server
Per-file encryption
Contents of each file encrypted with a unique key
Large files are stored in parts with a unique key per part
Encrypted contents, encryption keys, file part mapping are stored separately
