Final answer:
The recommended modifications after a security breach in a Department of Defense organization dealing with military products are to strengthen access control measures and implement stricter guidelines for internet use, while maintaining internet access for employees and physical access policies.
Step-by-step explanation:
Following a security breach in a Department of Defense organization dealing with military products, there are several modifications that should be made to the Internet use policy and physical access policy. One important modification is to strengthen access control measures, which may include implementing two-factor authentication, requiring stronger passwords, and regularly reviewing and updating access privileges. Another modification is to implement stricter guidelines for Internet use, such as prohibiting the download of certain file types or limiting access to certain websites.
However, it is not necessary to completely remove internet access for all employees (option B) or abolish physical access policies (option C). While some restrictions may be necessary, completely eliminating internet access or physical access policies can hinder productivity and convenience for employees.
In summary, the recommended modifications after a security breach in a Department of Defense organization dealing with military products are to strengthen access control measures and implement stricter guidelines for internet use, while maintaining internet access for employees and physical access policies.
