Types of Scans
On the Sygate Technologies web site, you can choose from one of the following types of
scans.
Quick Scans
The Quick Scan is a brief, general scan that encompasses several scanning processes. It
usually takes 20 seconds or less to accurately scan your device’s ports, protocols, services,
and possible Trojans. The results are recorded in the Agent’s Security Log.
Stealth Scans
The Stealth scan scans your device using specialized stealthing techniques, which mimic
portions of legitimate computer communication to detect the presence of a computer. The
Stealth scan takes about 20 seconds to complete and is most likely not recorded in the
Security Log.
Trojan Scans
The Trojan scan feature scans all of your device’s 65,535 ports for active Trojan horse
programs that you or someone else may have inadvertently downloaded. The Trojan scan
takes about 10 minutes to complete. A list of common Trojans is available on the web site.
TCP Scans
The TCP scan examines the 1,024 ports that are mainly reserved for TCP services, such as
instant messaging services, to see if these ports are open to communication. Open ports can
indicate a dangerous security hole that can be exploited by malicious hackers.
It scans ports on your device that are connected to devices such as routers and proxies for
users connecting to the web site through such a device. The scan takes about 20 minutes to
complete and is logged by the Agent as a scan event in the Security Log.
UDP Scans
The UDP scan uses various methods and protocols to probe for open ports utilizing UDP.
The UDP scan will scan ports on your device that are connected to devices such as routers
