IPS-4200 IDM-HTTPS & Browser

learnsec · ‎04-12-2013

Hello,

although we all know he problem of Cisco IPS's with Java, and knowing that java vulnerabilities are increasing, updating Java version is not allowed else we lose the ability to open IDM for the IPS's.

Another thing is appearing now, is that I will have, each time i want to open an IDM session of the IPS, to clear my browser history and cookies to be able to log on to the IPS, otherwise i got the error of we could not load the Server, IPS_IPAddress:443.

Is this related to any java parameters?

Note: occurring with 4240 IPS’s

Increasing the Memory Size of the Java Plug-In

To correctly run IDM, your browser must have Java Plug-in 1.4.2 or 1.5 installed. By default the Java Plug-in allocates 64 MB of memory to IDM and ASDM. IDM and ASDM can run out of memory while in use, which can cause IDM and ASDM to freeze or display blank screens. Running out of memory can also occur when you click Refresh. An OutofMemoryError message appears in the Java console whenever this occurs.

You must change the memory settings of Java Plug-in before using IDM and ASDM. The mandatory minimum memory size is 256 MB.
