8. Six months into development, the core team assigned to implement a new internal piece of software must convene to discuss a new requirement with the stake holders. A stakeholder identified a missing feature critical to the organization, which must be implemented. The team needs to validate the feasibility of the newly introduced requirement and ensure it does not introduce new vulnerabilities to the software and other applications that will integrate with it.

    Which of the following methods should the security administrator select the best balances security and efficiency?

    • Temporarily permit outbound internet access for the pacs so desktop sharing can be set up 
    • Have the external vendor come onsite and provide access to the PACS directly
    • Set up VPN concentrator for the vendor and restrict access to the PACS using desktop sharing
    • Set up a web conference on the administrator’s pc; then remotely connect to the pacs
