I have a question. What is high integrity level?

I doubt that I should be the one to explain it, but I'll try:
The levels are sort of like account types, in that:

Admin accounts can do certain things and access certain folders/files.
Standard user accounts can do fewer things and access fewer folders/files.


Programs running at the high integrity level can do certain things and access certain folders/files.

Programs running at the medium integrity level can do fewer things and access fewer folders/files.

Programs running at the low integrity level can do even fewer things and access even fewer folders/files.

There are more integrity levels than those 3; but hopefully, you get my point.


Some night when you cannot sleep, read this this long post:
MSE worries
...that post has been known to cure insomnia :-)


If anyone finds any flaws or typos in that long post, please let me know.



For those that don't want to read that long post, the executive summary is:

Don't turn off the UAC - unless you have another way to handle app integrity levels.

Don't run apps (especially a browser that is loading Flash) at the high (or system) integrity level.

Yep - but I could have just linked to the words of others to explain it.

Instead, I rambled on in my own words from memory...
...thus my caveat that you quoted :-)


The wiki link above is somewhat dated. It does not cover how Chrome handles integrity levels and there are some statements in that article that I'm not too sure about:

(e.g. "Consequently, a process cannot interact with another process that has a higher IL.")

I understand that the wiki article attempts to be brief - thus not every statement will be true 100% of the time; but there is definitely interaction between IE's "parent" process that runs at the medium level and IE's "children" processes (the tabs) that run at the "low" level.

I cannot find the article right now, but I seem to recall at one of these "find the flaw" competitions - some group managed to elevate the Chrome browser to the System Integrity Level. That is one huge flaw.



But - back on topic:
Since I think that I was the first to speak ill of the program...
...I hope that the OP's subsequent silence was not my fault.

Oh that high integrity level. I thought you were talking about security levels.
