The US Cybersecurity and Infrastructure Security Agency (CISA) has released a comprehensive cybersecurity guide specifically tailored for the Healthcare and Public Health (HPH) sector . This guide aims to address vulnerabilities and provide best practices for mitigating healthcare IT security risks .
The guide incorporates insights from vulnerability scanning and web application scanning programs  , as well as data collected from enrolled organizations and various sources. It leverages the renowned MITRE ATT&CK framework to contextualize vulnerability trends in the HPH sector .
Specific vulnerabilities faced by the HPH sector, such as encryption weaknesses and unsupported software , are highlighted in the guide. These vulnerabilities often lead to data breaches, ransomware attacks , and denial of service incidents . The guide focuses on areas such as asset management, access control , web application vulnerabilities , identity management , and device security . It offers guidance on crucial areas like email security , phishing prevention , password management  , access control , monitoring , and data protection practices . The importance of secure-by-design principles in the development of HPH products is also emphasized .
Proper vulnerability management  , patching  , and configuration management are covered comprehensively in the guide . Organizations are urged to maintain up-to-date server and application patching , conduct regular asset inventories , and promptly address any misconfigurations. The guide provides recommendations on securing assets and managing their security effectively .
Additionally, the guide offers vulnerability remediation guidance  , allowing HPH organizations to prioritize patching based on internal network architecture and risk posture  . It specifically draws attention to five vulnerabilities that have been frequently exploited by attackers , including the infamous Log4Shell bug and critical flaws in PHP and Microsoft Exchange .
By implementing the recommendations outlined in this guide , HPH organizations can significantly reduce their cybersecurity risk and protect the sensitive data entrusted to them . CISA urges these entities to be vigilant in their vulnerability mitigation practices to proactively prevent and minimize the impact of cyber threats .
