• Question 96:

  George, a security professional at an MNC, implemented an Internet access policy that allowed employees working from a remote location to access any site, download any application, and access any computer or network without any restrictions. Identify the type of Internet access policy implemented by George in this scenario.

  A. Permissive policy

  B. Paranoid policy

  C. Prudent policy

  D. Promiscuous policy

  Correct Answer: A

  Explanation: Permissive policy is the type of Internet access policy implemented by George in this scenario. An Internet access policy is a policy that defines the rules and guidelines for accessing the Internet from a system or network. An Internet access policy can be based on various factors, such as security, productivity, bandwidth, etc. An Internet access policy can have different types based on its level of restriction or control. A permissive policy is a type of Internet access policy that allows users to access any site, download any application, and access any computer or network without any restrictions. A permissive policy can be used to provide maximum flexibility and freedom to users, but it can also pose significant security risks and challenges. In the scenario, George implemented an Internet access policy that allowed employees working from a remote location to access any site, download any application, and access any computer or network without any restrictions. This means that he implemented a permissive policy for those employees. A paranoid policy is a type of Internet access policy that blocks or denies all Internet access by default and only allows specific sites, applications, or computers that are explicitly authorized. A prudent policy is a type of Internet access policy that allows most Internet access but blocks or restricts some sites, applications, or computers that are deemed inappropriate, malicious, or unnecessary. A promiscuous policy is not a type of Internet access policy, but a term that describes a network mode that allows a network interface card (NIC) to capture all packets on a network segment, regardless of their destination address.

• Question 97:

  Ashton is working as a security specialist in SoftEight Tech. He was instructed by the management to strengthen the Internet access policy. For this purpose, he implemented a type of Internet access policy that forbids everything and imposes strict restrictions on all company computers, whether it is system or network usage.

  Identify the type of Internet access policy implemented by Ashton in the above scenario.

  A. Paranoid policy

  B. Prudent policy

  C. Permissive policy

  D. Promiscuous policy

  Correct Answer: A

  Explanation: The correct answer is A, as it identifies the type of Internet access policy implemented by Ashton in the above scenario. An Internet access policy is a set of rules and guidelines that defines how an organization's employees or members can use the Internet and what types of websites or services they can access. There are different types of Internet access policies, such as: Paranoid policy: This type of policy forbids everything and imposes strict restrictions on all company computers, whether it is system or network usage. This policy is suitable for organizations that deal with highly sensitive or classified information and have a high level of security and compliance requirements. Prudent policy: This type of policy allows some things and blocks others and imposes moderate restrictions on company computers, depending on the role and responsibility of the user. This policy is suitable for organizations that deal with confidential or proprietary information and have a medium level of security and compliance requirements. Permissive policy: This type of policy allows most things and blocks few and imposes minimal restrictions on company computers, as long as the user does not violate any laws or regulations. This policy is suitable for organizations that deal with public or general information and have a low level of security and compliance requirements. Promiscuous policy: This type of policy allows everything and blocks nothing and imposes no restrictions on company computers, regardless of the user's role or responsibility. This policy is suitable for organizations that have no security or compliance requirements and trust their employees or members to use the Internet responsibly. In the above scenario, Ashton implemented a paranoid policy that forbids everything and imposes strict restrictions on all company computers, whether it is system or network usage. Option B is incorrect, as it does not identify the type of Internet access policy implemented by Ashton in the above scenario. A prudent policy allows some things and blocks others and imposes moderate restrictions on company computers, depending on the role and responsibility of the user. In the above scenario, Ashton did not implement a prudent policy, but a paranoid policy. Option C is incorrect, as it does not identify the type of Internet access policy implemented by Ashton in the above scenario. A permissive policy allows most things and blocks few and imposes minimal restrictions on company computers, as long as the user does not violate any laws or regulations. In the above scenario, Ashton did not implement a permissive policy, but a paranoid policy. Option D is incorrect, as it does not identify the type of Internet access policy implemented by Ashton in the above scenario. A promiscuous policy allows everything and blocks nothing and imposes no restrictions on company computers, regardless of the user's role or responsibility. In the above scenario, Ashton did not implement a promiscuous policy, but a paranoid policy. References: , Section 6.2
