Best Way to Ensure Compliance of Outsourced Service Providers with Information Security Policy

D.

As regular audits can spot gaps in information security compliance, periodic audits can ensure that outsourced service provider comply with the enterprise's information security policy.

Incorrect Answers: A: Penetration testing can identify security vulnerability, but cannot ensure information compliance.

B: Service level monitoring can only identify operational issues in the enterprise's operational environment.

It does not play any role in ensuring that outsourced service provider complies with the enterprise's information security policy.

C: Training can increase user awareness of the information security policy, but is less effective than periodic auditing.

The BEST way to ensure that outsourced service providers comply with the enterprise's information security policy is through periodic audits (option D).

Periodic audits help to evaluate the effectiveness of the outsourced service provider's controls and assess compliance with the enterprise's information security policy. Through an audit, the enterprise can verify that the service provider is adhering to contractual obligations, complying with legal and regulatory requirements, and implementing appropriate security controls to protect the enterprise's information assets.

Penetration testing (option A) is a method of evaluating the security of a system or network by simulating an attack. While penetration testing can be a useful tool to identify vulnerabilities in the service provider's systems, it does not ensure compliance with the enterprise's information security policy.

Service level monitoring (option B) is a process of tracking and measuring the performance of an outsourced service provider against agreed-upon service level agreements (SLAs). While SLAs are important for ensuring that the service provider meets the enterprise's requirements, they do not address compliance with the enterprise's information security policy.

Security awareness training (option C) is an important component of an overall information security program, but it is not sufficient to ensure that outsourced service providers comply with the enterprise's information security policy.

In summary, while each of the options listed can play a role in ensuring that outsourced service providers comply with the enterprise's information security policy, periodic audits are the BEST way to verify compliance and assess the effectiveness of the service provider's security controls.
