Megan, a cybersecurity specialist, is reviewing the port configuration of a critical server in her organization's network. An nmap scan reveals that TCP ports 21 (FTP), 443 (HTTPS), and 3389 (RDP) are open. Given the organization's strict security policy that mandates the use of secure, encrypted protocols for all remote connections and data transfer, Megan needs to determine which port(s) should be disabled to comply with this policy. Which port(s) should Megan disable to align with the organization's secure protocol requirements?

Kevin, an IT security analyst a large corporation, receives an alert about unusual activity on an office workstation. He discovers a suspicious executable, sync_tool.exe, running in the background and a corresponding batch file scheduled in the Windows Task Scheduler to execute hourly. The batch file, named sync.bat and located at C:\Windows\Tasks, contains the following commands:
- @echo off
- rem Sync system data
- net use Z: \10.0.0.150\data_share /user:sync_user /p:yes
- Z:\tools\sync_tool.exe
- net use Z: /delete
Kevin observes that sync_tool.exe is not part of any standard software on the workstation and notes its regular communication with external IP addresses. Evaluate the batch file and the behavior of sync_tool.exe to determine the likely type of malware present on the workstation.
