CSSP: DOMAIN 5 OPERATIONS
Physical and Environmental Controls for the Datacenter
Logical Cloud Infrastructure
Risk Assessments of Physical and Logical Infrastructure
PHYSICAL AND ENVIRONMENTAL DESIGN
In establishing a physical security function within a cloud environment, the following must be considered:
The security needs for the equipment and services being protected
The human resources that are in place for physical security
How legacy physical security efforts have been managed and staffed prior to transition to cloud
The financial resources available for these efforts
PHYSICAL AND ENVIRONMENTAL DESIGN
Physical security normally takes one of four forms in design and implementation
Mechanical, electronic and procedural controls
Detection and response procedures
Personnel identification, authentication, and access control
HUMAN RESOURCES CONTROLS
The purpose of the human resources physical control is to minimize the risk of the personnel closest to the data disrupting operations and compromising the cloud. Consider the following measures:
Roles and responsibilities
Separation of Duties
PHYSICAL LOCATION OF THE CSP FACILITY
Check if the location of the facility falls under any active seismic zone and the risks thereof.
Facility should not be located in a geographic region which is prone to:
Flooding, landslides or other natural disasters
Political, ethnic, communal or social unrests
Easy and quick accessibility of the facility’s location
Physical & Environmental Security Policy
User Account Termination Procedures
Incident Reporting & Response Plan
Emergency Response Plan
Facility Layout – emergency exits, positioning of CCTV cameras, secure entry points
Fire Exit Route Map & Fire Order Instructions
Emergency Evacuation Plan & Procedures
Crisis Communication Procedures
Emergency Contact Numbers

Maintenance Schedule of Electrical, Generator & CCTV
List of Authorized Personnel allowed entry inside facility
Security Staff profiles – bio & background information
Background Check Reports of Security Staff (must be performed every year)
Annual Maintenance Contracts for key equipment & devices (focus on SLAs for equipment/devices downtime & restoration)
Check whether all the documents are updated and current. The documents must be reviewed by the CSP at least once in a year. Should include revision data and signoff
Further, the policy and procedure documents (that are suitable for employee viewing) should be made available through a common Intranet site where authorized employees of the CSP can access them anytime for reference.
Check whether the CSP has security awareness program in place. At the minimum, the CSP should ensure that employees are given adequate security awareness training at least once a year and receive sign off from them. Also, new employees joining the organization shall undergo a security orientation session as part of the induction program where key policies and procedures are to be covered. To make the program effective, a senior staff from the security team must conduct the session
If the CSP is compliant with global security standards like ISO 27001 ISMS or any other industry-specific standard :
Verify the compliance certificate and its validity.
Look for verifiable evidence of resources allocation – budget and manpower to sustain the compliance program.
Verify internal audit reports and evidence of remedial actions for thefindings.

American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) Technical Committee 9.9 has created a set of guidelines for temperature and humidity ranges in the datacenter
Temperature between 64 and 80 degrees Fahrenheit
Humidity should be between 40 and 80 percent
Cable management strategy should be in place to minimize airflow obstructions caused by cable and wiring
Hot/Cold aisles should be established
