31 HITRUST: THREAT CORRELATION REPORT 31

32 CSF Controls Related to Threats CSF Control for Suspicious IP addresses, Command and Control, Infection Vectors Control Reference: *01.i Policy on the Use of Network Services Control Text: Users shall only be provided access to internal and external network services that they have been specifically authorized to use. Authentication and authorization mechanisms shall be applied to users and equipment. Implementation Requirement: The organization shall specify the networks and network services to which users are authorized access. 32

33 CSF Controls Related to Threats CSF Control for Employee Education Control Reference: *02.e Information Security Awareness, Education and Training Control Text: All employees of the organization and contractors and third party users shall receive appropriate awareness training and regular updates in organizational policies and procedures, as relevant for their job function. Implementation Requirement: Awareness training shall commence with a formal induction process designed to introduce the organization's security and privacy policies, state and federal laws, and expectations before access to information or services is granted and no later than 60 days after the date the employee is hired. Ongoing training shall include security and privacy requirements (e.g., objective, scope, roles and responsibilities, coordination, compliance, legal responsibilities and business controls) 33

34 CSF Controls Related to Threats CSF Control for Monitoring System Use (network monitoring) Control Reference: *09.ab Monitoring System Use Control Text: Procedures for monitoring use of information processing systems and facilities shall be established to check for use and effectiveness of implemented controls. The results of the monitoring activities shall be reviewed regularly. Implementation Requirement: The organization shall employ automated tools to support near real-time analysis of events and maintain an audit log to track prohibited sources and services. Inbound and outbound communications shall be monitored at an organization-defined frequency for unusual or unauthorized activities or conditions. 34

35 CSF Controls Related to Threats CSF Control for Network Security Management (network monitoring) Control Reference: *09.m Network Controls Control Text: Networks shall be managed and controlled in order to protect the organization from threats and to maintain security for the systems and applications using the network, including information in transit. Implementation Requirement: Technical controls shall be implemented to safeguard the confidentiality and integrity of covered information passing over the organization's network and to/from public networks. Technical tools and solutions shall be implemented and used to identify the vulnerabilities and mitigate the threats, including intrusion detection system (IDS), and vulnerability scanning. The organization shall employ tools and techniques, such as an IDS, to monitor events on the information system, detect attacks, and provide identification of unauthorized use of the system. 35

36 CSF Controls Related to Threats CSF Control for malicious attachments Control Reference: *09.j Controls Against Malicious Code Control Text: Detection, prevention, and recovery controls shall be implemented to protect against malicious code, and appropriate user awareness procedures on malicious code shall be provided. Implementation Requirement: Protection against malicious code shall be based on malicious code detection and repair software, security awareness, and appropriate system access and change management controls. 36

37 CSF Controls Related to Threats CSF Control for Removable Media Control Reference: *09.o Management of Removable Media Control Text: Formal procedures shall be documented and implemented for the management of removable media. Implementation Requirement: The organization shall formally establish and enforce controls for the management of removable media and laptops including restrictions on the type of media and usage, and registration of certain types of media including laptops. (disable autorun, sanitize media before connecting) 37

38 CSF Controls Related to Threats CSF Control for Vulnerability Patching (Top Exploits) Control Reference: *10.m Control of technical vulnerabilities Control Text: Timely information about technical vulnerabilities of systems being used shall be obtained; the organization's exposure to such vulnerabilities evaluated; and appropriate measures taken to address the associated risk Implementation Requirement: Specific information needed to support technical vulnerability management includes the software vendor, version numbers, current state of deployment (e.g. what software is installed on what systems) and the person(s) within Appropriate, timely action shall be taken in response to the identification of potential technical vulnerabilities. Once a potential technical vulnerability has been identified, the organization shall identify the associated risks and the actions to be taken. Such action shall involve patching of vulnerable systems and/or applying other controls. 38
