Creating a Cybersecurity program for a small business is straight forward. There are five functions that every security program must address.
The first step in any good cybersecurity program is to identify and assess the assets that impose a risk to the organization. Such as computer systems, people, data, facilities, etc.)
In the process of identifying these assets, understanding the importance these assets have to the objectives of the organization is critical. This information will be used to define the organization’s risk strategy.
Once the assets have been identified and classified by their importance to the organization’s objective, the development and implementation of safeguards are needed to ensure critical services are delivered. Protecting
After protecting the critical systems, data, and assets, the next step is to develop and implement the appropriate policies, procedures, and systems to detect events that could impact the critical systems and processes.
Once risk events are detected, how are those events responded to? Creating and following the proper policies and procedures to handle events is needed and communicated to all parties.
When a risk event is detected and it has been appropriately responded to, the recovery process is then started. The function of recovery is to make sure the critical system is functioning normally and improvements to the environment are evaluated.
This process is a very rudimentary process when creating a cybersecurity program. There are many steps and processes between each step and function. The NIST publications are very good at describing in more detail the different steps.
I recommend reviewing and familiarizing yourself with these documents before implementing a structured cybersecurity program. These frameworks are great guidelines.
