The purpose of command and control (C&C) for network-aware malware is to allow an attacker to remotely control compromised systems. This includes sending commands to the malware, receiving data from the infected host, and updating the malware to evade detection or enhance its capabilities.

References: The CBROPS course materials cover the topic of network-aware malware and the role of command and control servers in managing such malware

Application whitelisting/blacklisting is a technology used to control which applications are allowed to execute on a company’s corporate PCs. Whitelisting allows only approved applications to run, while blacklisting prevents specific applications from running. This approach is effective for managing application usage across an enterprise.

The exhibit shows a Stealthwatch dashboard displaying information on alarming hosts, alarms by type, and today’s alarms. On the left side under “Top Alarming Hosts,” there are five host IP addresses listed with their respective categories indicating different types of alerts including ‘Data Hoarding’ and ‘Exfiltration.’ In “Alarms by Type” section at center top part of image shows bar graphs representing various alarm types including ‘Crypto Violation’ with their respective counts. On right side under “Today’s Alarms,” there’s a table showing the details of each alarm such as the host IP, the alarm type, the severity, and the time. The potential threat identified in this dashboard is that there are two active data exfiltration alerts, one for host 10.201.3.149 and another for host 10.10.101.24. Data exfiltration is the unauthorized transfer of data from a compromised system to an external destination, such as a command and control server or a malicious actor. This can result in data loss, breach of confidentiality, and damage to the organization’s reputation and assets. References := Cisco Cybersecurity Operations Fundamentals - Module 7: Network and Host Forensics
