Ways To Make The Human Factor A Non-Issue In Cybersecurity
The implementation of adequate computer security measures requires contemplating technical, organizational and legal aspects, however, in many cases very little attention is paid to the importance of the human factor in computer security. People represent the weakest link in computer security, unlike computers, people may not follow the instructions exactly as they were dictated, in addition, they may carry out actions that provoke a security hole in the network of the organization such as the installation of malicious software on your computer, disclosure of sensitive information to third parties, among others.
It is fundamental, therefore, to contemplate the role of people and their relationship with the computer systems and networks of the organization. In addition, the availability on the Internet of all types of tools and programs, as well as the necessary documentation for their installation and configuration, has complicated the situation for those responsible for information technology of the organizations, since now the “temptation” is at a simple click away. In short, a basic principle to be taken into account from the point of view of computer security is that all implemented solutions are useless in the face of ignorance, plus 75% of the problems is caused by failures in the configuration of the equipment or due to misuse by the staff of the organization itself.
The main experts in IT security have already warned us in recent years about the need to consider the human factor as one of the most important and decisive when implementing a good information security management system. That is why, the implementation of a Computer Security Management System should consider the human factor as one of its key elements, contemplating aspects such as:
- Implementation of computer security measures.
- Adequate training and awareness of employees.
- Involvement of managers and managers.
- Approval of internal regulations on the use of computer tools in the organization.
- Any other measure of positive contribution
Among the actions or good practices to be executed are:
Proper use of emails:
The way to ensure that the exchange of information is carried out properly and under the necessary protection is through the development of a policy that includes the means used in this activity. In this policy should be incorporated:

- Prevent other users from using their identity to access the computer system.
- Do not insert CD-ROMs, USB or other means without prior checking that they do not contain any risks.
