1. What is a Chief Information Security Officer?

The Chief Information Security Officer (CISO), also known as the Director of Information Security, is responsible for digital security within a company. In other words, they are the ones who establish and execute strategies aimed at protecting sensitive data and corporate assets.

Most of the time, this professional reports directly to the CEO and may work in collaboration with the Chief Technology Officer (CTO) and the Chief Information Officer (CIO).

Their duties include preventing intrusions into the corporate infrastructure, protecting and defending it. In practice, it is common for security teams responsible for privileged accounts to report to a CISO.


2. What is the difference between CIO and CISO?

The difference between these two professionals lies in the scope of their work, the corporation’s business strategy, and the use of data.

This is because the CIO is responsible for understanding and sharing the company’s strategies with the IT team and ensuring operational efficiency. They are the ones who determine which tools are necessary to perform a task. On the other hand, the CISO is directly responsible for planning the digital security of the institution.

Regarding data, the CIO uses it to design IT and business strategies, while the CISO focuses on promoting the security of information stored in the company’s systems.


3. What qualifications should a CISO have?

Some certifications are recognized in the cybersecurity market as essential for a CISO. These include the Certified CISO program, also known as CCISO, provided by the EC-Council; CISSP, which is equivalent to a master’s degree in cybersecurity; and CISM from ISACA, which focuses specifically on governance and management capabilities.

However, it is expected that these professionals also possess skills such as good oral and written communication, the ability to handle pressure, and experience in strategic planning and execution.

In addition, those aspiring to be CISO should:

  • Have experience in risk management in information security.
  • Understand concepts of Linux, networking, and virtualization.
  • Be familiar with security standards in the field.
  • Be knowledgeable about current data protection laws.
  • Have experience with Secure SDLC and DevSecOps.
  • Understand security automation.

4. CSO is not the same as CISO

The Chief Information Security Officer (CISO) is responsible for information security within a company, while the Chief Security Officer (CSO) covers overall organizational security. In practice, the CSO manages physical and information security, ensuring control of access to physical spaces and protecting digital assets.


5. What to do to become a Chief Information Security Officer

With attractive salaries, the role of CISO attracts many professionals. However, to assume this position, it is necessary to have extensive experience in the field of information security, a leadership profile, and the ability to explain technical issues in understandable language.

It is also essential to invest in knowledge, although many courses are expensive or provide insufficient content, and to convey credibility, as you will be dealing directly with the CEO and investors. Another crucial step for those aspiring to become a CISO is to pursue certifications such as CCISO, CISSP, CISM, as mentioned in this article, or certifications like Certified Information Systems Auditor (CISA) and Certified Ethical Hacker (CEH), which are more generalist but relevant for those seeking to be cybersecurity executives.
