In the incident handling and response (IH&R) process, backing up the data on affected systems is a critical step that usually falls under the Containment phase. The Containment phase is crucial for limiting the scope and severity of an incident, ensuring that it does not spread further or affect additional systems. Backing up affected systems during containment is essential for several reasons: it preserves a snapshot of the system in its current state for forensic analysis, ensures that data is not lost if the system needs to be wiped or altered during the response process, and helps in the recovery process if data is corrupted or lost.

By performing a complete backup of the infected system during the Containment phase, Alice ensures that there is a reliable copy of all data and system states before any major actions, such as eradication or deeper forensic analysis, are taken. This step is also preparatory for the potential use of the backup in analyzing how the incident occurred and in restoring system functionality after the incident is resolved.

Thenetstat -ancommand is used to display network connections, routing tables, and a number of network interface statistics. It is particularly useful for identifying unusual volumes of traffic to and from a system, which can be indicative of a DoS/DDoS attack. The option-ashows all active connections and the TCP and UDP ports on which the computer is listening, and-ndisplays addresses and port numbers in numerical form. This can help the incident handling and response (IH&R) team to identify suspicious patterns, such as a large number of connections from a single source or to a specific port, which are common during DoS/DDoS attacks.

Malicious downloads initiated through manipulated office documents typically involve macro abuse. Macros are scripts that can automate tasks within documents and are embedded within Office documents like Word, Excel, and PowerPoint files. While macros can be used for legitimate purposes, they can also be abused by attackers to execute malicious code. When an office document with a malicious macro is opened, and macros are enabled, the macro can run arbitrary code that leads to malicious downloads, installing malware or performing other unauthorized actions on the victim's system.

Macro abuse has become a common vector for cyber attacks, as it exploits the functionality of widely used office applications. Attackers often craft phishing emails with attachments or links to documents that contain malicious macros, tricking users into enabling macros to execute the malicious code. This method is effective for bypassing some security measures since it relies on user interaction and exploitation of legitimate features.

The ECIH Endpoint Security module identifies EDR systems as the cornerstone of modern endpoint incident response. Advanced attacks targeting intellectual property often bypass traditional antivirus controls.

Option C is correct because EDR provides continuous monitoring, behavioral detection, rapid containment, and automated response across endpoints. This capability is critical during high-risk periods such as product launches.

Options A, B, and D are important but insufficient alone for real-time detection and response.

Therefore, deploying a robust EDR system is essential.
