There is a reason that the Java security settings have disabled the TLSv1, and TLSv1.1 algorithms. One must understand that these changes to the Java security implementation will open your system up to Java vulnerabilities that exist in the wild. # =MD5, SSLv3, DSA, RSA keySize Advanced Tab > Advanced Security Settings > Enable: Use TLS 1.0, Use TLS 1.1, Use TLS 1.2, Use TLS 1.3.įor anyone who comes looking for these solutions, it is important to understand the IT system security implications involved.
Here is the changes to my "curity" file and the line numbers for anyone wanting to make similar changes. I have started testing these java changes on several systems and already I am seeing success on 1 of the systems by modifying the "curity" file only. It is great to hear that I'm not the only one who has experienced mixed results with regards to modifying the "curity" file. Was there a reboot required? Did you have to close all your browsers? It seems like something must be missing from your response to get it to work. I'd also really like to know why modifying "curity" worked for markhatfield and not for my system. I'd really like to continue to keep Java's latest version, but at this point, I see no way. The only thing that worked was uninstalling jre1.8.0_291 and updating my system variable path to point to jre-7u80 (javaw.exe). I did not reboot after installing jre-7u80, perhaps a new path would have been created after a reboot. At this point, nothing I could do would get this version of Java to work with ASDM. So I checked my system variable path and it was still pointing to the location of jre1.8.0_291 (javaw.exe). I was also certain that disabling jre1.8.0_291 in the Configure Java application had no effect on my system. Now I was certain that I had "jre-7u80-windows-圆4" installed because I could see it in the Configure Java application, after selecting the "Java" tab, and then click the "View." button. That is when I got the error message: "No appropriate protocol (protocol is disabled or cipher suites are inappropriate)" I tried to enable all protocols and then disable all the protocols but TLS1.0 in the Configure Java application too. "The server selected protocol version TLS10 is not accepted by client preferences "
Up to this point, the error message never changed. I'm not 100% sure why modifying the "curity" file worked for markhatfield, but not for my system. I knew at this point that Java 8u291 was the issue, so I installed jre-7u80, then I opened the Configure Java application, click the "Java" tab, then the "View." button, and disabled both x86 and 圆4 versions of Java 8u291.

Third, I used my Oracle Support account to download "jre-7u80-windows-圆4.exe". Second, I tried to comment out the entire line starting with "".

This did not work for me, but I will explain why it did not work and how I got ASDM to work on Windows 10 Pro Version 21H1, OS Build 19043.1055.įirst, I tried to simply remove the "SSLv3, TLSv1, TLSv1.1" from the line in your comment. Update: Originally logged into Spiceworks with the wrong account.
