• Physical security: Microsoft maintains physical security of your data through 24-hour monitoring of the data centers. To gain entry into the datacenter, Microsoft requires their staff to authenticate themselves in many ways, including biometric scanning. These personnel who secure the data centers are unaware of which data is located where because different servers contain different information. Data is not grouped together per company. Also, Microsoft ensures physical security of your data by demagnetizing and destroying faulty drives and hardware.
• Data security: Whether your data is at rest on Microsoft servers or in transit with SSL/TLS, encryption protects your data. To prevent and/or detect any tampering of data, Microsoft uses threat management, security monitoring and file/data integrity. Advanced security and reliability is provided with the Exchange Online Protection to help protect your information and access to email against spam and malware.
• Logical security: Microsoft only runs processes that are whitelisted to minimize risk from malicious codes. There is also a threat management team that focuses on the prevention and mitigation of malicious access. Port scanning, perimeter vulnerability scanning and intrusion detection are additional ways Microsoft prevents and detects malicious access. Also, limiting human access to your data can be done by activating Lockbox.
