ASL Roma 1's implementation of an advanced security operation center called HyperSOC allows it to convert its cybersecurity approach from reactive to proactive, ensuring effective management of cyber threats. The adoption of this safeguard has led to a significant reduction in security incidents, despite the growing number of attacks at national and European level, because of the continuous monitoring of the attack surface of the infrastructure, which guarantees a higher level of security than other peers in the sector.

In an increasingly interconnected and constantly evolving healthcare environment, there are numerous cybersecurity challenges that hospitals must face to guarantee patients high-quality health services, avoid interruptions in supply, optimize the use of devices, and effectively manage cyber risks. These challenges require the use of cutting-edge technologies and real-time availability of diverse data and information.

Risk managers—especially C-suite and boards of directors—looking to establish a culture of OT cyber awareness and risk remediation proactivity in their organizations need to establish a formal and measurable program approach. The program must provide a shared vision and a practical roadmap that makes sense because it relates to many of the unique characteristics of their organization, OT environment, business model, and risk appetite.

Securing connectivity in operational technology (OT) environments is crucial for the safety of critical infrastructure and maintaining the uninterrupted service it provides. Leaving unnecessary open ports, protocols, and services exposed, along with directly connected devices to the internet, such as programmable logic controllers (PLCs) and human machine interfaces (HMIs), greatly increases the risks of cyberattacks.

The HHS Office for Civil Rights proposes substantial rule changes to the long-standing Health Insurance Portability and Accountability Act (HIPAA) Security Rule. While details on the proposed rule changes remain unclear, HHS plans to issue a Notice of Proposed Rulemaking (NPRM) by the end of the year. These changes are believed to be the most substantial changes since the HIPAA Security rule went into effect in 2003
