Domain name system filtering stops malware downloads by blocking requests to malicious addresses, reducing the attack surface without scanning every file transferred.

Most defenders focus on stopping the traffic, but the real danger is the collateral damage to legitimate users during the mitigation process.

Port scanning reveals which services run on your devices, allowing attackers to select the exact vulnerability that matches your specific software version.

Network beaconing often persists after initial cleanup because attackers embed timing logic in legitimate system processes rather than obvious malware files.

Disabling network access to remote desktop removes the primary attack surface, yet many administrators leave this port open due to legacy maintenance habits that create persistent liability.

Web filtering blocks known threats but fails against encrypted traffic and zero-day exploits, requiring deeper inspection for true security.

Routine software updates often mask beaconing traffic, allowing attackers to maintain access for months while appearing as normal background noise.

Cloud firewalls filter traffic at the network edge but cannot inspect encrypted payloads or stop attacks that originate from inside your authorised environment.

IPS devices drop traffic silently, creating blind spots that can hide successful intrusions from your monitoring tools if logging is misconfigured.
