The EDR output shows the process tree of the ransomware infection. The root node is NO-AV.exe, which is a malicious executable that disables antivirus software and downloads the DearCry ransomware. The NO-AV.exe process was launched on cpt-ws026 by a user named John. The DearCry.exe process was then launched on cpt-ws026 by NO-AV.exe and propagated to other devices via SMB. Therefore, the ransomware originated from cpt-ws026 and NO-AV.exe. Verified Reference:

A Service Level Agreement (SLA) is the document used to specify due dates for the remediation of high- and critical-priority findings. SLAs outline the responsibilities of the service provider, including time frames for addressing issues or vulnerabilities, based on their severity. By setting clear timelines for remediation, SLAs ensure that critical security vulnerabilities are addressed in a timely manner. CASP+ emphasizes the importance of SLAs in maintaining accountability for security operations and ensuring compliance with organizational security policies.

Framework codeprovides a standardized structure and set of conventions that all team members can follow, ensuring consistency in coding styles across the development team.
Option A (Chain of custody): This relates to tracking and managing code changes for accountability, not standardizing coding styles.
Option C (Two-person integrity): Ensures review and approval for code changes but does not enforce uniform coding styles.
Option D (Code coverage for unit testing): Focuses on test quality rather than addressing inconsistent coding styles.

A network traffic analyzer (also known as a packet sniffer) is the best tool to identify credentials being transmitted in plaintext, such as those used in Telnet sessions. Since Telnet transmits data without encryption, a network traffic analyzer can capture the traffic between the client and the network switches, revealing sensitive information, including login credentials, in clear text. This tool helps identify insecure protocols and enables remediation by switching to encrypted alternatives like SSH. CASP+ highlights the importance of using secure protocols and tools like traffic analyzers to identify vulnerabilities in network communications.
