Cybersecurity has become a critical issue. If not handled with utmost professionalism, a company can become vulnerable to hackers, leading to dire consequences for its finances and reputation. At the forefront of cybersecurity efforts is the CISO, whose role has grown so pivotal that they often engage directly with senior management…
A data breach can cost a company millions and significantly affect customer retention. The repercussions can last for years. To safeguard against such threats, companies of a particular size must consider employing a CISO.
A CISO (Chief Information Security Officer) is an executive tasked with safeguarding cybersecurity, meaning the protection of vital data.
What does a CISO do?
A CISO’s week involves extensive interaction with teams within the IT department, including a dedicated group of security experts.
Some of their key responsibilities include:
- Crafting and leading a cybersecurity strategy.
- Preventing and detecting cyber threats.
- Creating security awareness training programs, as the negligence of a single employee can jeopardize the system.
- Reporting on cybersecurity procedures to management.
- Assessing the necessary investment in cybersecurity.
The CISO formulates recommendations driven by the latest cybersecurity research—considering the frequent discovery of new vulnerabilities—to determine whether the infrastructure requires upgrades and to plan for new security tools to combat emerging threats.
The CISO also maintains regular communication with management. They must routinely present their cybersecurity vision and ensure alignment with corporate objectives.
In the event of a significant incident, the CISO plays a crucial role in designing and implementing a recovery plan following a breach in the current defense system. They are typically charged with restoring operational control.
Do all companies need a CISO?
The need for a CISO depends on the company’s size. What is clear is that having at least one person dedicated to cybersecurity is indispensable today. Startups can opt to outsource this role to external firms, while large and even some medium-sized companies should employ a CISO.
What skills should a CISO possess?
A CISO often holds one or more IT certifications in cybersecurity. They must especially master cloud and application security. Awareness of the risks posed by technologies such as generative AI is also crucial.
Additionally, the CISO must be well-versed in the major security standards established by prominent global organizations like the NIST (National Institute of Standards and Technology) and ISO (International Organization for Standardization). Skills in management, communication, negotiation, and leadership are also valuable.
What is the difference between a CIO and a CISO?
In the realm of IT responsibilities, the CIO (Chief Information Officer) occupies the highest rank. They shape the overarching vision for IT strategy and oversee significant IT initiatives.
The CISO, contrastingly, has a complementary mission. They ensure each CIO-led initiative complies with essential cybersecurity requirements crucial for the company’s effective operation.
The CISO’s role has grown so critical that many leading American firms, especially those within the Fortune 500, now position the CISO at an equal level to the CIO.
The evolution of the CISO role
As cybersecurity has become a vital concern, the CISO increasingly interacts directly with top executives: CEOs, CFOs, and others. These leaders seek updates on potential risks and the strategies implemented to mitigate them. From a management perspective, cybersecurity extends beyond IT; it is a matter concerning the company’s very survival.
Boards of directors now insist on detailed information regarding technological risks and the defined protection policies, delving into every detail of company operations.
