When it comes to cybersecurity, there is no single strategy to follow. But looking to the experts and analysts who work tirelessly every day on the latest threats and trends can provide valuable direction.
Gartner has identified six top cybersecurity trends for this year. These are things healthcare leaders should consider. Of the six, the ones we at Avertium consider the most helpful and beneficial are:

Trend: “Continuous threat exposure management programs gain momentum”
Gartner's predictions in this regard are surprising. By 2026, organizations that prioritize security investments through Continuous Threat Exposure Management (CTEM) programs are expected to “achieve a two-thirds reduction in breaches.”
CTEM is an approach to managing vulnerabilities and risks that allows security professionals to protect their organizations at the required pace of change. This is a huge opportunity, especially in the medical field, where breaches can have significant financial and life-threatening consequences, and where CTEM programs are not yet widely available.
Gartner explains: “The purpose of CTEM is to develop a consistent and actionable security posture remediation and improvement plan that executives can understand and architecture teams can act on.”
Think of CTEM as the flip side of traditional threat detection and notification programs, making it less reactive than a SIEM or endpoint security solution. Operating in a purely reactive manner tends to result in a costly security posture. The attacker has reached the end of his chain of kills, and it will take humans, not technology, to solve the problem.
Healthcare organizations are constantly adding new payers, providers, biotech devices, technologies, and regulations, creating many potential footholds around the perimeter for threat actors to exploit. The purpose of CTEM is to limit or prevent leaks in the first place by discovering and identifying potentially exposed assets and devoting time and effort to mitigation.
Gartner provides a framework for doing so, but the key fundamentals include continuous external scanning: repeating penetration tests, vulnerability scans, and third-party supply chain scans. Once an organization understands its risks, it can prioritize and remediate those risks, limiting its attack surface. Point-in-time assessments are only as valuable as the nature of your environment at the time, so consistent and ongoing testing and scanning is key. As new code and systems are introduced into production, the attack surface changes and must be re-evaluated and remediated.
