Cyber threat intelligence aims to research and analyze trends and technical developments in the areas ofcybercrime, hacktivism, and espionage. These are the main sources of malicious cyber activities that pose risks to organizations and individuals. Cyber threat intelligence helps to understand the motivations, capabilities, tactics, techniques, and procedures of various threat actors and groups.

An objective of public key infrastructure (PKI) is to independently authenticate the validity of the sender's public key. PKI is a system that uses cryptographic keys to secure communications and transactions. PKI involves a trusted third party called a certificate authority (CA) that issues digital certificates that link a public key with an identity. The recipient can use the CA's public key to verify the sender's certificate and public key.

Elliptic curve cryptography (ECC)is a more efficient form of public key cryptography as it demands less computational power and offers more security per bit. ECC is based on the mathematical properties of elliptic curves, which are curves that have a special shape that makes them suitable for cryptography. ECC can achieve the same level of security as other public key algorithms with much smaller key sizes, which reduces storage and bandwidth requirements.

Trend/variance-detection toolsare tools that look for anomalies in user behavior. These tools use statistical methods to establish a baseline of normal user activity and then compare it with current or historical data to identify deviations or outliers. These tools can help to detect unauthorized access, fraud, insider threats, or other malicious activities.

The second line of defense in cybersecurity includes risk management monitoring, and measurement of controls. This is because the second line of defense is responsible for ensuring that the first line of defense (the operational managers and staff who own and manage risks) is effectively designed and operating as intended. The second line of defense also provides guidance, oversight, and challenge to the first line of defense. The other options are not part of the second line of defense, but rather belong to the first line of defense (A), the third line of defense C, or an external service provider (D).

Within the NIST core cybersecurity framework, the identify function is associated with using organizational understanding to minimize risk to systems, assets, and data. This is because the identify function helps organizations to develop an organizational understanding of their cybersecurity risk management posture, as well as the threats, vulnerabilities, and impacts that could affect their business objectives. The other functions are not directly related to using organizational understanding, but rather focus on detecting (A), recovering C, or responding (D) to cybersecurity events.

The ''recover'' function of the NIST cybersecurity framework is concerned with planning for resilience and timely repair of compromised capacities and service. This is because the recover function helps organizations to restore normal operations as quickly as possible after a cybersecurity incident, while also learning from the incident and improving their security posture. The other options are not part of the recover function, but rather belong to the identify (B), respond C, or protect (D) functions.

Availability can be protected through the use of redundancy, backups, and business continuity management. This is because these measures help to ensure that systems, data, and services are accessible and functional at all times, even in the event of a disruption or disaster. The other options are not directly related to protecting availability, but rather focus on enhancing confidentiality (A), integrity C, or awareness (D).

The BEST basis for allocating proportional protection activities when comprehensive classification is not feasible is a business dependency assessment. This is because a business dependency assessment helps to identify the criticality and sensitivity of business processes and their supporting assets, based on their contribution to the organization's objectives and value proposition. This allows for prioritizing protection activities according to the level of risk and impact. The other options are not as effective as a business dependency assessment, because they either use a single classification level allocation (A), which does not account for different levels of risk and impact; require a significant amount of time and resources to perform a business process re-engineering (B); or rely on external parties to cover potential losses without reducing the likelihood or impact of incidents (D).

From a regulatory perspective, the MOST important thing for the healthcare organization to determine when outsourcing its patient information processing to a third-party Software as a Service (SaaS) provider is the incident escalation procedures. This is because incident escalation procedures define how security incidents involving patient information are reported, communicated, escalated, and resolved between the healthcare organization and the SaaS provider. This is essential for complying with regulatory requirements such as HIPAA, which mandate timely notification and response to breaches of protected health information. The other options are not as important as incident escalation procedures from a regulatory perspective, because they either relate to technical aspects that may not affect compliance (A, B), or operational aspects that may not affect patient information security (D).
