An Intrusion Prevention System (IPS) device placed inline is best suited to block attacks on a network actively. Being inline allows the IPS to analyze and take action on the traffic as it passes through the device, effectively preventing malicious traffic from reaching its target. The IPS can detect and block a wide range of attacks in real-time by using various detection methods, such as signature-based detection, anomaly detection, and policy-based detection. Unlike Host-based Intrusion Prevention Systems (HIPS), web proxies, or load balancers, an inline IPS is specifically designed to inspect and act on incoming and outgoing network traffic to prevent attacks before they reach network devices or applications.References:The Incident Handler (CREST CPTIA) certification materials discuss network security controls and emphasize the role of intrusion prevention systems in protecting networks against threats.

As of my last update, the most recent NIST standard for incident response was NIST Special Publication 800-61 Revision 2 (800-61r2), titled "Computer Security Incident Handling Guide." This document provides guidelines for establishing an effective incident response program, including preparation, detection and analysis, containment, eradication, recovery, and post-incident activity.

References:The document is a key resource in the field of incident response, frequently cited in the CREST CPTIA curriculum for its comprehensive guidelines on managing and responding to cybersecurity incidents.

Internal intelligence feeds are derived from data and information collected within an organization's own networks and systems. Jian's activities, such as real-time assessment of system activities and acquiring feeds from honeynets, P2P monitoring, infrastructure, and application logs, fall under the collection of internal intelligence feeds. These feeds are crucial for identifying potential threats and vulnerabilities within the organization and form a fundamental part of a comprehensive threat intelligence program. They contrast with external intelligence feeds, which are sourced from outside the organization and include information on broader cyber threats, trends, and TTPs of threat actors.References:

The correct sequence for scheduling a threat intelligence program involves starting with the foundational steps of defining the project scope and objectives, followed by detailed planning and scheduling of tasks. The sequence starts with reviewing the project charter (1) to understand the project's scope, objectives, and constraints. Next, building a Work Breakdown Structure (WBS) (9) helps in organizing the team's work into manageable sections. Identifying all deliverables (2) clarifies the project's outcomes. Defining all activities (8) involves listing the tasks required to produce the deliverables. Identifying the sequence of activities (3) and estimating resources (7) and task dependencies (4) sets the groundwork for scheduling. Estimating the duration of each activity (6) is critical before developing the final schedule (5), which combines all these elements into a comprehensive plan. This approach ensures a structured and methodical progression from project initiation to execution.References:

Incident triage is the phase in the incident handling and response process where identified security incidents are analyzed, validated, categorized, and prioritized. This step is critical for determining the severity of incidents and deciding on the allocation of resources for effective response. It involves initial analysis to understand the nature of the incident, its impact, and urgency, which guides the subsequent response actions.

References:The incident triage phase is a foundational concept in the CREST CPTIA curriculum, emphasizing the importance of a structured approach to responding to security incidents, ensuring that resources are focused where they are needed most.

Avoiding VPN (Virtual Private Network) and other secure network channels is not a countermeasure to eradicate inappropriate usage incidents. On the contrary, using VPNs and secure network channels is a best practice for enhancing security, as these technologies help protectdata in transit, ensuring that it is encrypted and less susceptible to interception or eavesdropping. Countermeasures for inappropriate usage typically involve enhancing security and monitoring, not reducing the security of communications.

Whaling is a specific type of phishing attack that targets high-profile executives or individuals within an organization, often with the intent to steal sensitive information or gain access to their accounts for financial fraud. The term "whaling" is used because it targets the "big fish" of an organization. Given that Sam identified the targets of the attack as high-profile executives, the described scenario is indicative of a whaling attack.

References:The CREST CPTIA curriculum includes a section on different types of phishing attacks, including whaling, emphasizing the strategies attackers use to target individuals based on their roles within an organization.

Risk assessment is the risk management process that involves identifying risks, estimating their impact on the organization, and determining the sources of those risks to recommend appropriate mitigation measures. The goal of a risk assessment is to understand the nature of potential threats, vulnerabilities, and the consequences of those risks materializing, allowing an organization to make informed decisions about how to address them effectively. Risk assumption involves accepting the potential impact of a risk, risk mitigation focuses on reducing the likelihood or impact of risks, and risk avoidance involves taking actions to avoid the risk entirely.References:The CREST CPTIA course materials include discussions on risk management processes, outlining the importance of risk assessment in identifying and preparing for potential security threats.
