Information Security: learn about the 4 fundamental principles

by | Apr 7, 2020 | BLOG

Information security is a topic that is on the spotlight worldwide, and professionals from the field are the ones who need to be most concerned with this type of measure, since they maintain the data security system of an entire company under surveillance through their practices. 

This significantly reduces the risks of a possible cyberattack on a corporate network, preventing leaks of confidential data and cyber threats, such as ransomware. 

The list below comprises the 4 fundamental principles, also called CIA, that must be put into practice simultaneously to maintain consistent data security within your company.

1st Principle – Confidentiality

It is essential to ensure that data stored in any system is accessed only by authorized people, which means that you need to have a credentials system.

It is recommended that each credential has a level of access and that only relevant information is available to its use.

2nd Principle – Integrity 

Integrity must exist to ensure that information is not modified by anyone who is not authorized to perform that task.

You are required to have a system that checks if a message has been changed in the analysis or submission process. Some features that ensure the security of this information are:

  • Hash
  • Hash-linked encryption

3rd Principle – Availability

This principle is one of the simplest but least taken into account, and it is based on the assurance that information will be available as soon as requested.

That is, the user can access a server whenever they want without experiencing problems of slowness or error when trying to access the system.

To ensure that this information is available when the user wants it, you must have some resources at your organization, such as:

  • Backup
  • Raid
  • No break
  • High availability and contingency

4th Principle – Authenticity

Authenticity aims to identify and map out what actions the user has taken to perform a certain task, such as: editing, transferring, copying, etc.

This type of measure is used as an internal and external security monitoring means so that if there is any type of information leak, one can identify who was responsible and when it has taken place.

Other resources used to ensure these pillars of Information Security are:

  • Encryption
  • Passwords
  • Biometrics
  • Digital certificates
  • Digital signature

Conclusion

If you are an information security professional and have not yet implemented all of these data security measures at your company, be advised that your corporation is vulnerable to various types of information leaks and incalculable damage.
