Today, information security is a key element of every company’s operations. To ensure effective management and protection of information, organizations create positions such as CISO and CSO. What are the differences between these two roles and what are their main responsibilities?

CISO vs CSO – duties and responsibilities

CISO (Chief Information Security Officer) and CSO (Chief Security Officer) are two managerial positions responsible for various aspects of security in the organization. Although their responsibilities may overlap, the differences between them are important.

CISO

The CISO mainly focuses on information security in the organization. This includes protecting data, systems, networks and other IT resources from threats such as hacker attacks, data leaks, system failures, data loss and other cybersecurity events.

The main responsibilities of a CISO include:

1. Developing and implementing information security strategies and policies.
2. Conducting and supervising security audits.
3. Risk analysis and information security risk management.
4. Monitoring and analyzing information security incidents.
5. Create and maintain emergency plans and incident response procedures.
6. Training employees in information security and increasing awareness of cybersecurity threats and best practices.
7. Cooperation with other departments to secure processes and data on which they operate.
8. Ensure compliance with legal regulations and industry standards regarding information security.
9. Cybersecurity budget management.
10. Reporting to the management board on the security of IT systems.

CSO

The CSO is responsible for broadly understood security in the organization, including both physical security and cybersecurity. As such, a CSO can manage all aspects of security, including protection of assets, employees, customers, partners and information assets.

The main responsibilities of a CSO include:

1. Developing and implementing overall security strategies for the organization.
2. Coordinating activities related to physical security, such as facility security, access control systems and crisis management measures.
3. Conducting and supervising security audits.
4. Collaborate with IT and CISO to implement cybersecurity policies and procedures.
5. Collaborate with other departments to secure infrastructure, assets and staff.
6. Monitoring and assessing threats and implementing countermeasures.
7. Create and maintain emergency plans and incident response procedures.
8. Ensure compliance with safety regulations and standards.
9. Coordinating other activities related to the protection of personal data and privacy.
10. Managing the security budget and reporting to the management board on the organization’s security status.

Summary

In summary, a CISO focuses primarily on information security and cybersecurity, while a CSO has broader responsibilitiesthat include both physical security and cybersecurity. In some organizations, these positions may be closely related or even combined into one (CISO/CSO), but in larger organizations they are usually separate roles.

Remember the biggest threats

One of the most important areas of responsibility of both CISOs and CSOs is proper education of employees, which will effectively raise their awareness of threats and improve their resistance to cyberattacks and manipulations.

With the help of Practical Anti-Phishing Training – education based on realistic simulations of cyberattacks, micro-training in the event of a mishap and measurable effects – you can strengthen your employees’ cybersecurity while tracking clear KPIs, with which you will be able to measure and report the effectiveness of your activities.

We describe what criteria to follow and how to implement them so that they provide real value from the perspective of the CISO and other stakeholders.
