You are a cybersecurity analyst monitoring network traffic and notice several hosts communicating directly with each other using non-standard ports. What could this indicate?
Authorized internal file sharing among employees
A misconfigured firewall rule set
Regular network traffic caused by software updates
A botnet attempting to coordinate activities among infected devices
Direct communication between hosts using non-standard ports is often indicative of peer-to-peer communication. This can be a sign of malicious activity, such as a botnet attempting to control compromised machines within the network. Regular monitoring and analyzing of such traffic can help identify and mitigate potential threats.
