Hands-On Labs

As an ethical hacker, it is important to not only be able to test security systems but also understand that a good policy structure drives effective security. While this chapter discusses policy, laws, and rules of engagement, now is a good time to review the SANS Information Security Policy Templates page. These templates should be useful when you are helping an organization promote the change to a more secure setting.

Equipment Needed

A computer and Internet connection

Estimated Time: 15 minutes

Lab 1-1 Examining Security Policies

  • Step 1. Go to the SANS Information Security Policy Templates page located at https://www.sans.org/security-resources/policies.

  • Step 2. Click the Network Security category, and then click the Acquisition Assessment Policy hyperlink.

  • Step 3. Click the PDF hyperlink and review the Acquisition Assessment Policy. It defines responsibilities regarding corporate acquisitions and the minimum requirements of an acquisition assessment to be completed by the information security group.

  • Step 4. Return to the main Policy Templates page, click the Old/Retired category, click the Risk Assessment Policy hyperlink, click PDF, and review the template. This policy template defines the requirements and provides the authority for the information security team to identify, assess, and remediate risks to the organization’s information infrastructure associated with conducting business.

  • Step 5. Return to the main Policy Templates page, click the General category, click the Ethics Policy hyperlink, click PDF, and review the template. This template discusses ethics and defines the means to establish a culture of openness, trust, and integrity in the organization.
