Information Security: 5 Best Practices to Implement in Your Company


Digitalization is becoming increasingly relevant in companies, highlighting the dependence on new technologies. All this makes information security essential to prevent companies from having their data unprotected.

In this post, we explain what it consists of and provide five best practices in information security to start implementing.

What is information security?

Information security refers to the protection of information and information systems against unauthorized access, use, disclosure, interruption, modification, or destruction. It has become a critical obligation for organizations.

Companies of all sizes and sectors handle a wealth of information, from personal and sensitive employee and customer data to financial and intellectual property information. This information is a valuable asset that, if compromised, can cause serious harm to data subjects and significant damage to an organization’s reputation and financial viability.

Therefore, organizations must establish procedures to ensure information security, protect against threats that may affect it, and ensure the continuity of their operations.

Procedures to Ensure Information Security

These procedures should include information security policies, access controls, information security training, security incident management, and disaster recovery and business continuity plans.

  • Information security policies provide a framework for managing information security in an organization. These policies define employee responsibilities, security requirements for information systems, and procedures for handling security incidents.
  • Access controls are measures that limit authorized persons’ access to information. These can include passwords, key cards, and two-factor authentication.
  • Information security training is essential to ensure that all employees understand information security and their responsibilities regarding it. This training should cover topics such as the secure handling of information, identifying security threats, and responding to security incidents.
  • Security incident management involves identifying, tracking, and resolving security incidents. These incidents typically include phishing attacks, data breaches, and different types of malware.
  • Disaster recovery and business continuity plans detail how an organization will respond to a security incident that results in a significant loss of information or operational capacity and proceed to nullify or minimize its effects.

Key Terms in Information Security

There are three key terms that allow us to understand the concept and that constitute the characteristics of information security: confidentiality, integrity, and availability.


It refers to the protection of information from disclosure to unauthorized parties. Confidentiality measures include data encryption, access control, and user authentication.


It refers to protecting information against unauthorized modification or deletion. This ensures that the information is accurate and complete. Integrity measures include version control, backups, and intrusion detection systems.


It refers to ensuring that information and information systems are available for use when needed. Availability measures include system redundancy, disaster recovery, and business continuity planning.

These three characteristics of information security should guide organizations in developing security policies, procedures, and controls.

However, information security is not a one-size-fits-all solution that can be applied uniformly across organizations. Each organization must assess its risks and develop an information security strategy tailored to its needs.

In addition, information security is not a static state but an ongoing process. As threats and risks evolve, so do security measures. This requires constant vigilance, regular evaluation of safety policies and procedures, and ongoing user education and training.

5 Best Practices in Information Security

Among the best practices in information security, implementing these five in your company, which we have detailed below, is the starting point for any corporate information security procedure.

1. Security Updates

Security updates are critical to protecting organizations’ information systems.

These updates contain patches that address the latest vulnerabilities detected in the software. Keeping systems up-to-date minimizes the risk of cyberattacks.

2. Access to information control

Access control is another crucial practice. It involves ensuring that only authorized individuals have access to sensitive information.

The organization should implement role-based access control policies to limit access to information based on its category and the job responsibilities of its employees.

3. Backups

Regular backups are essential for data recovery in the event of information loss.

The organization should make backups regularly and store them in a safe place. In a cyberattack, backups allow information to be restored and operational activity to be maintained.

4. Password management

Effective password management is vital for information cybersecurity

It’s critical to encourage employees to use strong, unique passwords for each account and to renew them regularly. Additionally, it is advisable to implement two-factor authentication to add an extra layer of security.

5. Staff awareness

Finally, staff awareness is crucial in preventing the success of social engineering techniques. This is one of the cybersecurity tips that you should keep in mind.

Your employees need to be informed about cybersecurity best practices and how to identify potential threats. Regular training is critical for them to stay up-to-date on the latest threats and how to prevent them.
