The Evolving Work of the CISO in 2024

The challenges, responsibilities, and the modern cybersecurity battlefield for CISOs in 2024 

I speak to many cybersecurity professionals, and if there’s one ongoing and pervasive concern they all highlight about the nature of their role, it’s change and “the unknown.” Only this week, the conflict in Lebanon has seen unpredictable upheaval as the region grapples with challenges from localized tensions to cyber threats. Across the globe, well-funded nation-state attackers are looking for new targets for disruption, putting manufacturing, finance, utility, telecoms, and law enforcement in the firing line. Not a day goes by we don’t see yet another zero day vulnerability and compromised multi-national in the headlines. 

In an age where cyber threats continually evolve and the digital world intertwines ever more deeply with our daily lives, the Chief Information Security Officer (CISO) role has never been more pivotal. However, as we look at 2024, the CISO’s responsibilities, challenges, and tools are evolving rapidly – and it’s a lot of responsibility and pressure to stay ahead. 

A Shift in CISO Responsibilities for 2024 

Cybersecurity leaders need to do more than lead a team of cybersecurity professionals in the year to come, they need to create an organization-wide culture of cyber-resilience and security awareness and lead an internal public relations exercise to show all parties the benefits and importance of good digital hygiene.

Historically, or “back in my day,” CISOs were primarily responsible for setting up firewalls, maintaining antivirus software, and ensuring network security. Today, the role has expanded to a strategic one, encompassing risk management, compliance, and even public relations. CISOs are now often part of executive teams, contributing to business strategies with a security-centric viewpoint.  

2024 Pressure Cooker Environment  

It’s fantastic that the role has been recognized for how important it is, and that cybersecurity is part of the boardroom conversation, but it does require a new set of public-facing skills and a broader portfolio of hats the modern CISO has to wear.

Every organization is a potential target for cyberattacks, and a single breach can result in substantial financial losses, reputational damage, and legal consequences – we all know the drill. This constant threat environment means CISOs are always on high alert. Moreover, the expectation of being virtually breach-proof puts immense pressure on them, making the role both mentally and emotionally taxing and making it essential that every cybersecurity professional be aware of their mental health to avoid occupational burnout 

Budgeting for Cybersecurity in 2024  

With the rise in cyber threats, there’s been a corresponding increase in cybersecurity budgets, but in a modern sales climate, this is never guaranteed. Many CISOs are constantly seeking extra cybersecurity funding to mitigate a scattergun approach from well-funded adversaries with (metaphorically) infinite time on their hands. Even if organizations are investing more in security tools, training, and personnel, allocating funds effectively still remains a challenge. CISOs must make tough decisions on where to place hard-won funds: new technologies, employee training, or perhaps third-party services?

Balancing between proactive and reactive measures while also maximizing cybersecurity ROI, makes budgeting a complex task without resorting to an approach of stimulus and response/plate juggling and firefighting. It’s tricky to allocate funds to mitigate the unknown, but that’s what organizational finance departments expect, and an agile approach to spending isn’t an option.  

We all have standards and legislation to meet, be it regional or industry-specific, and meeting that is an obvious call for spend, but then a risk-based approach, prioritizing areas most vulnerable to your organization’s specific threats while ensuring adaptability, is often a solid approach. Nailing down blanket solutions that give the most cover for spend and investing in foundational security practices – such as preventing lateral movement, implementing zero trust, managing technical debt, or network segmentation/microsegmentation – will be key. Fostering a culture of security awareness and allocating funds for emerging technologies. Balancing proactive and reactive strategies while maintaining reserves for unforeseen events allows CISOs to optimize spend, ensuring robust defenses without (hopefully) overextending resources. 

Staffing Woes (AKA The Great Resignation) 

The cybersecurity industry has faced a talent shortage for years. It’s one of the most significant issues I hear when talking to our clients. As cyber threats become more sophisticated, the need for skilled professionals grows. CISOs often grapple with recruiting and retaining top talent. Additionally, training current staff to deal with new threats is a continual challenge, especially given the rapid pace of technological change.  

Essential Tools in a CISO’s Arsenal  

Several tools have become indispensable for modern CISOs:  

  • Threat Intelligence Platforms: These provide real-time information about emerging threats, helping organizations stay one step ahead.  
  • Endpoint Detection and Response (EDR): EDR solutions monitor endpoints (like user devices) for signs of cyber threats, playing a crucial role in early threat detection.  
  • Security Information and Event Management (SIEM): SIEM solutions provide real-time analysis of security alerts generated by various hardware and software. 
  • Zero Trust Security Models: Given the distributed nature of modern work environments, zero trust models, which require verification for every user and device trying to access network resources, have become crucial. 
  • AI and Machine Learning: AI tools can predict, detect, and respond to threats more quickly than human counterparts.  

There are many benefits, from timesaving to budgetary, of consolidating several functions within a trusted platform. A single real-time service (such as our own) can use existing EDR agents like SentinalOne or Crowdstrike to give clearer environment visibility, and offer file integrity monitoring, workload hardening, and service account protection with microsegmentation and zero trust best practices, to mitigate zero day attacks and comply with the likes of PCI DSS4. 

Challenges on the Horizon for CISOs in 2024 

Several challenges loom large for CISOs in 2024:   

  • Further Rise of IoT: The explosion of Internet of Things (IoT) devices has expanded the attack surface dramatically. Knowing device and application relationships is becoming ever more important to see vulnerabilities, connections, and dependencies that bad actors could exploit. 
  • Regulatory Landscape: With data breaches becoming common, many countries are enacting stricter data protection laws, requiring CISOs to ensure compliance across different regions as well as within their own sectors. 
  • Sophisticated Attacks: Phishing attacks, ransomware, and state-sponsored attacks are becoming more sophisticated and persuasive, requiring constant vigilance, education, and adaptation.  
  • Remote Work: The shift towards remote work  (and BYOD) has made network perimeters more porous and challenging to defend.  
  • The Quantum Shift: Quantum computing – a literal quantum-level disruptor – is here, and a profound challenge to the cybersecurity industry due to its immense processing power. Quantum computers, in the hands of bad actors, can potentially decrypt even the most secure cryptographic protocols currently in use. 

Beyond Technicalities: Soft Skills and Mental Health   

A CISO’s job isn’t just about understanding technology. Effective communication, leadership, and negotiation skills are becoming increasingly crucial. CISOs often act as a bridge between technical teams and top management and educate employees about cybersecurity best practices – which will only increase in the years to come.  

Furthermore, given the high-pressure nature of the job, CISOs are becoming more conscious of their mental health and work-life balance. Organizations, too, are recognizing the need to support their CISOs and employees in high-pressure roles, offering resources such as counseling and flexible work hours. As a manager, it will be the responsibility of the CISO to ensure the mental health of our colleagues, as well as ourselves, to create a solid team and a robust working environment, and to retain staff for the future. 

The Rocky Road Ahead  

The role of a CISO in 2024 is multidimensional.

While technology and tools play a significant part, the human aspect—be it in leadership, communication, or mental well-being—is becoming equally important. As cyber threats continue to evolve, so will the role of the CISO, requiring continuous learning, adaptability, and resilience. 

The CISO’s job is not for the faint-hearted. In 2024, the CISOs and their teams will make the difference between success and failure for many organizations. Honestly, at the risk of hyperbole, it’s a role for heroes. It’s a calling that requires technical expertise, communication skills, strategic foresight, management acumen, a crystal ball, and robust mental fortitude. However, for those who rise to the challenge, it offers an opportunity to be at the forefront of technology and organizational stability, safeguarding assets and data, and protecting business continuity in our increasingly connected and ever-changing world.
