Port scanning is a type of “network reconnaissance” carried out against a targeted network, allowing an attacker to see if the network is active and to find weak points in its security.
FAQs about Port Scanning
How can port scanning affect networks or devices?
If a network or device is participating in port scanning, one or more devices connected to the network could have been infiltrated without authorization and could be used by a third party for malicious and/or illegal purposes.
What do I do if my network is detected participating in port scanning?
Here are ways you can treat and avoid this:
- Perform a thorough virus and malware scan on your device using downloadable applications like the Microsoft Windows Malicious Software Removal Tool.
- If you have anti-virus software installed, make sure you’re always updated with the latest version.
- If you’ve completed the above but your device(s) is/are still acting strangely, bring to a third-party computer repair technician to solve the problem.
