Anna created her company's security policy to accept the majority of internet traffic, excluding several known dangerous services and attacks. Which type of security policy did Anna put into place?

The security policy that Anna implemented is best described as a permissive policy. This type of policy is characterized by a general acceptance of network traffic, where the default stance is to allow access unless explicitly restricted by rules for specific services or attack vectors. By accepting most internet traffic while only excluding known dangerous services and attacks, Anna is embodying the essence of a permissive approach. This method is often used to maintain greater operational flexibility while still addressing potential threats.

In contrast, a prudent policy would focus on risk management and might implement more stringent controls to minimize vulnerabilities. A promiscuous policy often refers to a network setting where devices indiscriminately accept all incoming traffic, which can pose security risks if not monitored correctly. A paranoid policy typically adopts a very restrictive approach, limiting access extensively which could hinder legitimate business functions. Hence, the distinction lies in Anna's decision to allow general access and only block specific known threats, aligning with a permissive policy framework.
