CS Mapping & Port Scanning
This lesson is part of Cyber Security · All levels
Summary
Network mapping and port scanning are techniques for mapping active hosts and finding open services on a network. Popular tools such as nmap can detect live systems, open ports, even running versions of services. In a security context, this technique is used to find gaps before an attacker finds them, and it must always be done with permission.
Key points
- Mapping identifies active hosts and network topologies.
- Port scanning detects an open port that could potentially be an access point.
- Status port: open, closed, filtered.
- Nmap is the standard tool for service scanning and detection.
- Always do the scanning with written permission from the network owner.
