Wow, my firewall is registering a portscan today from physicsforum.com. Are any of you guys h4x0r1ng me ? :rofl: :rofl: :rofl:
A firewall registering a portscan means that the firewall has detected and recorded an attempt to scan for open ports on a network or system. This could indicate that someone is trying to gain unauthorized access to the network or system.
A portscan is considered a potential security threat because it can reveal potential vulnerabilities in a network or system. By scanning for open ports, an attacker can identify services and applications that may be exploitable.
A firewall can detect a portscan by monitoring network traffic and looking for patterns that indicate a scan, such as a large number of connection attempts to different ports from the same IP address. Once a scan is detected, the firewall can register the source IP address and the ports that were scanned.
If your firewall registers a portscan, it is important to investigate the source of the scan and take appropriate action. This could include blocking the source IP address, closing any open ports that were scanned, and strengthening the security of your network or system.
No, a firewall cannot prevent all portscans. While a firewall can block many types of scans, determined attackers may find ways to bypass the firewall or use more sophisticated scanning techniques. It is important to regularly monitor and update your firewall and other security measures to stay protected against potential threats.
