Converged Identity and Access Management – Final

Final in the series “Converged Identity and Access Management”

ID and access managementThe IT infrastructure is the backbone of a converged solution, allowing key business data to be shared across systems. For example, a company’s physical security system typically does not have critical business data such as employee status, whereas the HR department’s IT system has such knowledge.

Converging physical security with IT security isn’t easy, but the extra effort it requires can be beneficial, especially for financial, healthcare, and defense organizations. Convergence affords organizations the opportunity to align security with overall business goals, streamline business processes such as provisioning and investigations, and centralize security operations and policies.

Developing common protocols for managing access to company assets and data enables more efficient provisioning and management. Different physical and logical security systems should leverage extendable interfaces of identity management solutions and thus stay in sync. The key benefit is that security personnel continue to use tools best suited to their jobs and HR personnel continue using HR tools. Converged security systems therefore allow users to improve Return on Investment (ROI).

Key Steps for Convergence

To bridge the organizational gap, the physical security department should work directly with the IT security team to identify:

  1. Authoritative sources of key data used to determine whether a person has permissions to use a resource or access an area.
  2. Compliance or audit needs.
  3. Any business or security concerns that are unique or are especially important to an organization.
  4. Various business processes such as on-boarding, off-boarding and the responsibilities of different systems.
  5. Policies for managing employees who doesn’t have any logical accounts, e.g., cleaning staff, caterers, etc.
  6. Privacy and security policies that clearly define what personal information is to be collected, how the information will be used, who can access the information, how the information will be protected, and how the individual will control its use and provide updates to the information over time.

Effective Convergence through Events Correlation

With converged access control, organizations can correlate disparate physical and IT security events. For example, it may not seem suspicious for an employee to use a computer. However, physical/logical correlation might ensure the employee is able to access logical resources, only after he has swiped his ID card at the entry door. Or, some of the logical resources can get locked for a user as soon as he leaves the premises by using his card at the door.

Conclusion

The convergence of Identity and Access control systems is helping enterprises better protect their intellectual property, monitor the access to restricted areas and comply with regulations. It improves the operational efficiency of existing physical security systems and resources. How organizations choose to implement this is should be aligned with their business strategy and security and compliance requirements.
