Aktív-Passzív (IMON-beállítások) KÜLÖNBSÉG -kis kék NOD letöltőablak!
The IMON module works in two basic modes: “active” and “passive”. In passive mode, IMON continuously transfers parts of currently downloaded files to the target application, and saves a temporary copy for itself. After last part is downloaded, IMON scans the file. When an infiltration is found, IMON displays a warning window and terminates connection. The disadvantage of this method is that already transferred part of file may contain essential part of the harmful file. In addition, when the application repeatedly attempts to download the infected file, it can use already downloaded part of the file and download only the “rest”, which might be considered as not being harmful.
In active mode, IMON downloads and scans whole files and only after that transfers them to target applications. This method is more secure, because in case of infiltration no data will be transferred. The disadvantage is that the application does not get at once, so it can not display the download process correctly (that’s why IMON display a download process longer than 5 seconds in a separate dialog window). In addition, this mode is not fully compatible with some data types (e.g. multimedia) that require data streams.
