A Step by Step Guide on how a Cybersecurity Risk Assessment is Performed

For each organization, risk assessment should be performed on a regular basis. These risk assessments provide protection against cyber attacks that occur on a daily basis.

It is a necessary action that must be carried out with attention and precision. The stages outlined below might serve as a guide for conducting a risk assessment.

In order to accomplish transactions and conduct daily business, almost every firm relies on information technology and information systems. During these trades, a great deal of risk is introduced. These hazards must be thoroughly investigated in order to guarantee that they are appropriately minimised.

It is necessary to conduct a cyber risk assessment in order to identify, estimate, and prioritise the threat to an institution’s business activities. Cyber risk assessment assists organisations in making educated decisions to support the implementation of appropriate risk responses by providing them with an executive summary.

We will go over the processes that should be followed when completing a cybersecurity risk assessment:

Understanding the scope of your organization’s assets as well as its size, complexity, and scope of assessment

It is critical to comprehend the architecture and specifics of the system that you are responsible for protecting.

To begin, you must clearly define what it is that you will be evaluating. You will be able to decide the extent of your assessment based on this information. It will also assist you in scheduling your time effectively, ensuring that you do not overlook any components or forget anything at all.

Establish an inventory of everything that needs to be evaluated. This comprises information such as data, partners, and vendors. Remove devices such as removal devices, data centres, code, and scripts from the network and identify the data exchanges that take place therein.

This first step will assist you in determining the likelihood of your cybersecurity risk assessment being effective. Make certain that you do not leave out any important assets, as doing so can have a negative impact on your findings.

Identifying the worth of an item

Knowing the asset worth of everything that needs to be analysed will assist you in understanding the significance of the process.

Determining the value of an asset can be challenging because it is influenced by a wide range of circumstances.

Consider problems such as: if the company loses its data, how much time and money would it take to rebuild the organisation from the ground up? You can question yourself how far your competitors would go in order to gather information about you. Is it possible to lose revenue if a compromise is reached, and how much damage will result as a result? Answering these questions will assist you in determining the value of your possessions.

Identification of vulnerabilities and threats

Make a list of probable and relevant threats to your systems that will aid you in doing your cybersecurity assessment in the future. Unauthorized access, internal attacks, misuse of privileges, data leakage, and unintended disclosure of information are all examples of dangers that can occur. Data loss as a result of insufficient backup procedures is also a vulnerability.

Internal auditing can aid you in identifying the portions of the system that are weak. In addition, performing a vulnerability check will provide you with information on areas that require further investigation.

Taking into consideration the cost of prevention

The value of the data or system should be evaluated at this stage to assess whether the expense of the mitigation strategies is justified in comparison to the value of the data.

This is the stage of implementation.

Using your assessment, you will be able to identify which controls you should put in place. The controls that have been identified will be implemented and put into action. The plan should always be both cost-effective and realistic in its implementation. Ensure that the controls are meeting the expectations of the organisation by constantly monitoring their performance.
