Ensuring that all areas of security have the proper controls is a primary reason why organizations use frameworks. Frameworks provide an organized structure for organizations to evaluate their security posture and implement the necessary security measures for their operations. Frameworks such as NIST, COBIT, and ISO 27001 provide guidance on how to develop, implement and monitor security policies, controls, and procedures for an organization. Additionally, frameworks provide a benchmark for organizations to measure their security posture against and create a roadmap for continued improvement.

A hypothesis is a statement that can be tested by threat hunters to establish a framework for threat assessment. A hypothesis is based on situational awareness and threat intelligence information, and describes a possible attack scenario that may affect the organization. A hypothesis can help to guide threat hunters in their investigation by providing a clear and specific question to answer, such as "Is there any evidence of lateral movement within our network?" or "Are there any signs of data exfiltration from our servers?".

RBAC (Role-Based Access Control) is a solution that would work best to assist the help desk with the onboarding and offboarding process while protecting the company's assets. RBAC is a method of granting access to resources based on the roles of users within an organization. RBAC simplifies the management of user permissions by assigning predefined roles to users based on their job functions, rather than granting individual permissions to each user. RBAC can help automate the onboarding and offboarding process by enabling the help desk to quickly create or delete user accounts and assign or revoke access rights based on the roles of the users1. RBAC can also help protect the company's assets by enforcing the principle of least privilege, which means that users only have access to the resources they need to perform their duties and nothing more2.

The most secure states for the certificate authority server when it is not in use are powered off and air gapped. Powering off the server will prevent any unauthorized access or tampering with the server while it is idle. Air gapping the server will isolate it from any network connections, making it inaccessible to remote attackers or malware. These measures will help to protect the integrity and confidentiality of the certificate authority server and its keys.

Credentialed scanning is a method of vulnerability scanning that uses valid user credentials to access the target systems and perform a more thorough and accurate assessment of their security posture. Credentialed scanning can help to reduce the number of false positives by allowing the scanner to access more information and resources on the systems, such as configuration files, registry keys, installed software, patches, and permissions .
