Predicting the future in cybersecurity is a fool's errand — specific attacks and tools are impossible to forecast. But directional trends are meaningful, and understanding where threats and controls are heading helps organizations make smarter investments.
Here's what's worth paying attention to heading into 2024.
AI-Powered Attacks Will Mature
Generative AI has already dramatically lowered the barrier to creating convincing phishing content. In 2024, expect this to extend further: AI-generated voice and video for executive impersonation, automated vulnerability research, and AI-assisted lateral movement in compromised environments.
The defensive implication: controls that depend on humans recognizing attack patterns from observable "tells" — poor grammar, unusual phrasing, unfamiliar senders — become less reliable. Technical controls (email security, MFA, EDR) become more important.
Ransomware Groups Will Continue Targeting Critical Infrastructure
Ransomware operators have consistently pushed boundaries, and critical infrastructure (hospitals, utilities, manufacturing) remains in the crosshairs. The combination of high disruption potential and organizations with mission-critical uptime requirements creates leverage for attackers.
For organizations in or adjacent to critical infrastructure: ransomware resilience (backup strategy, network segmentation, incident response planning) should be a top-tier priority.
Identity-Based Attacks Will Dominate
The perimeter is gone. Cloud-first and remote-work environments have shifted the battleground to identity. Credential theft, MFA bypass techniques, token theft, and session hijacking are consistently among the top initial access and lateral movement techniques.
Investing in identity security — phishing-resistant MFA, identity governance (who has access to what), privileged access management, and identity threat detection — is one of the highest-ROI security investments for most organizations going into 2024.
Supply Chain Risk Is Now a Board-Level Issue
Post-SolarWinds and post-MOVEit, the supply chain attack surface is well understood at the executive level in a way it wasn't three years ago. Expect more regulatory requirements around vendor risk management, more sophisticated questionnaire and assessment programs from enterprise customers, and more investment in software supply chain security.
Regulatory Pressure Will Increase
The SEC's new cybersecurity disclosure rules for public companies take effect in 2024, requiring material cybersecurity incident disclosure within four days. State privacy laws continue to multiply. International data protection regulations are tightening. Healthcare enforcement has been ramping up.
If your security program hasn't been thinking about regulatory requirements, 2024 is the year to start.
What This Means for Security Investment
The trends above consistently point toward the same investment areas: identity security, detection and response capabilities, vendor risk management, and governance that supports regulatory compliance.
That doesn't mean you throw out everything else. Foundational controls — MFA, patching, backups, incident response planning — remain the foundation. But if you're prioritizing where to invest additional resources, the trends above are informative.
Prediction with Humility
The threat landscape always surprises. The specific attack vectors that dominate 2024 news cycles may be things nobody is focused on today. The value of robust security fundamentals is precisely that they're effective against the known and unknown threat landscape alike.
Invest in fundamentals, stay current on the threat intelligence, and build an organization that can adapt.
