NIST Publishes Final Guidance on Establishing Zero Trust Architecture to Improve Cybersecurity Defenses
NIST has published the final version of its zero trust architecture guidance document (SP 800-207) to help private sector organizations apply this cybersecurity concept to improve their security posture. Zero trust is a concept that involves changing defenses from static, network-based perimeters to focus on users, assets, and resources. With zero trust, assets and user accounts are not implicitly trusted based on their physical or network location or asset ownership. Under the zero trust approach, authentication and authorization are discreet functions that occur with subjects and devices before a session is established with an enterprise resource. The use of credentials for gaining access to resources has been an effective security measure to prevent unauthorized access; however, credential theft – through phishing campaigns for instance – is now commonplace, so cybersecurity defenses need to evolve to better protect assets, services, workflows, and network accounts from these attacks. All too often, credentials are stolen and are used by threat actors to gain access to...
Protected Health Information of 129K Individuals Potentially Compromised in Behavioral Health Network Malware Attack
Behavioral Health Network (BHN), the largest behavioral health service provider in Western Massachusetts, has announced that malware was downloaded onto its computer systems that prevented files from being accessed. The security breach was discovered on May 28, 2020 when staff were prevented from accessing files. An investigation was immediately launched to determine the extent of the attack and whether any data had been exfiltrated by the attacker. Around July 17, 2020, BHN determined that an unauthorized individual had gained access to its systems on May 26, two days before the malware was introduced. While it was not possible to determine whether any data had been stolen by the attacker prior to the deployment of the malware, the possibility of data theft could not be totally ruled out. No reports have been received to date indicating patient data has been misused. An analysis of the affected systems revealed the protected health information of 129,571 current and former patients was potentially compromised. The systems that were accessible to the attacker contained names,...
Patches Released to Fix Critical Vulnerabilities in Citrix Endpoint Management / XenMobile Server
Two critical flaws have been found in Citrix Endpoint Management (CEM) / XenMobile Server. The flaws could be exploited by an unauthenticated attacker to access domain account credentials, take full control of a vulnerable XenMobile Server, and access VPN, email, and web applications and obtain sensitive corporate and patient data. CEM/ XenMobile Server is used by many businesses to manage employees’ mobile devices, apply updates, manage security settings, and the toolkit is used to support many in-house applications. The nature of the flaws make it likely that hackers will move to develop exploits quickly, so immediate patching is essential. The two critical flaws are tracked as CVE-2020-8208 and CVE-2020-8209. Information has only been released on one of the critical flaws – CVE-2020-8209 – which is a path traversal vulnerability due to insufficient input validation. If exploited, an unauthenticated attacker could read arbitrary files on the server running an application. Those files include configuration files and encryption keys could be obtained, which would allow sensitive...
Data Breaches Reported by University of Maryland Faculty Physicians and Highpoint Foot & Ankle Center
University of Maryland Faculty Physicians Inc. (FPI) has suffered a phishing attack in which the protected health information of patients of University of Maryland Medical Center (UMMC) may have been accessed by unauthorized individuals. FPI is the faculty practice plan for University of Maryland School of Medicine affiliated physician practice groups and provides support to physicians and staff who provide services at UMMC locations. Following the discovery of the unauthorized accessing of an FPI email account, the account was secured and a comprehensive investigation was conducted to determine the nature and scope of the breach. On May 26, 2020, FPI determined the email account was accessed by an unauthorized individual between February 6, 2020 and February 11, 2020. The email account contained the protected health information of 33,896 individuals. The types of information in the account varied from patient to patient and may have included the following data types in addition to patient names: Date of birth, medical record number, and clinical information related to the care...
OIG Identifies Barriers to the Use of Health Information Exchanges by the Department of Veteran Affairs
The Department of Veteran Affairs (VA) Office of Inspector General (OIG) has conducted a review of VA facilities and community providers to identify any barriers that are hampering the use of health information exchanges (HIEs). OIG identified several issues that need to be addressed to improve the exchange of health information. HIEs are used to share healthcare information for the purpose of coordinating and improving the continuity of care for veterans enrolled in a VA facility. Following a pilot program, the VA introduced the Veterans Health Information Exchange (VHIE), which uses two methods for sharing veterans’ data between VA facilities and members of VA healthcare teams: VA Exchange and VA Direct. OIG conducted a survey and interviews at 48 lower complexity Level 2 and 3 Veterans Health Administration (VHA) facilities, along with interviews of staff in the VHIE Program Office. OIG also met with the Office of Information Technology, Office of Community Care, Office of Rural Health, Cerner, and two state HIEs. According to the VHIE Program Office Director, all 140 VA...
