ReHIPS / Re: Various questions about Rehips
« Last post by fixer on November 11, 2019, 05:47:13 pm »
Hello, Cuslichavy.
Thank you for your interest in our product and welcome to our forum. And don't worry about questions, we're here to answer them :)

1. ReHIPS doesn't disable any other program security features and doesn't try to bypass or circumvent any of them, so no it shouldn't compromise any other program security including sandboxing.

2. Do you mean you can do it technically? Or should you do it? Technically no, if a program is isolated, it can't start other programs without isolation. Should you do it? It depends. If it's something trustworthy, why not. But I prefer to treat isolated programs as potentially compromised, so nothing goes from isolation out.

3. Can you give an example of different folders after update that causes a headache? Something like different version numbers in folder name? You can use wildcards to cover folders like this.

4. C:\ReHIPS subfolders are to exhange data with isolated programs. Like you want to edit a .doc-file, you put it there and edit it with isolated Word. Here is a blogpost about it https://forum.rehips.com/index.php?topic=9487.0 So putting a program in that folder isn't supposed to start it isolated. To create other folders simply create a new folder and give isolated environment permissions to it.

5. Wildcards are covered in this blogpost https://forum.rehips.com/index.php?topic=9647.0 Most likely there are multiple level of folders and you wildcarded only one level. Either wildcard all of them or wait for the next release where ** wildcard should be supported.

6. ReHIPS suspends a starting program at a very early state where it hasn't begun executing, so most likely ReHIPS did its thing OK and these few search results you observed were taken from elsewhere, maybe from cache, maybe some internal search is also started in parallel or something like this.

ReHIPS / Re: Various questions about Rehips
« Last post by Cuslichavy on November 11, 2019, 12:10:40 am »
I'm sorry for asking too many questions, but I have a few more.

5. I want Rehips to ignore a folder and allow the execution of every program in that file path. I tried using wildcards (like C:\GoodPrograms\*) but it didn't work, Rehips still alerted me and asked me how to treat that program. Am I doing something wrong or this is not supported?

6. In Visual Studio Code when you do a search it runs another program to perform that search, or at least I learned that from Rehips when it alerted me. I did a search, the program gave two results and Rehips kind of suspended that sub program. Once I allowed it, it gave the rest of the results. Rehips was late and couldn't prevent the execution of that program, at least partially. The same happened even after I permanently blocked that program. Is this a bug?

I'm using Windows 10 1903.

ReHIPS / Various questions about Rehips
« Last post by Cuslichavy on November 09, 2019, 02:49:20 am »
Hello, I've been using Rehips for a few days and I'd like to learn more about its features and limitations. I've a few questions.

1. Does Rehips compromise Chrome's or any other web browser's own sandboxing? I know Sandboxie does.
2. I run my browser non isolated. Can I open links from an isolated program to my non isolated browser?
3. Every time a program updates I have to give permissions again. I'm running Rehips in expert mode. This is even worse with Chrome because every update uses a different folder. How can I make a rule to let software auto update without Rehips notifying me each time? At least for Chrome. Rules is where I struggle the most right now. I also deleted the default rules for Chrome and Firefox in the default rules database but I made a backup first.
4. Folders in C:\ReHIPS. How do I make other folders beside Default and Browser. I made a new folder and gave rwx permissions to a environment, but didn't work, the program in that folder won't even run isolated. Do I have to change permissions of the actual folder (from Windows Explorer) authorizing a Rehips user to make it work or is there a better way to do this?

Thank you in advance.

PID is a Process ID. You can read more about it here https://en.wikipedia.org/wiki/Process_identifier In short words, it's a unique number assigned when a new process is started until it exits. So for example when you have multiple svchost.exe - s, by PID you can identify which one of them you need.

ReHIPS / What does PID mean as shown in the ReHIPS Log?
« Last post by Stephen on November 05, 2019, 08:53:02 am »
When I look at the ReHIPS log I see "PID" with a number shown in each entry. I assume that PID means Program ID, but what does the number mean?

ReHIPS / Re: Firefox as a default browser

When you install rules from the Programs tab, RulesManager comes into play. Here is a blogpost about rules installation https://forum.rehips.com/index.php?topic=9529.0

In short words, if some rule is already present in ReHIPS database, it won't be overwritten, only missing rules will be installed. So if you deleted Firefox rules, they'll be reinstalled. If you modified some other rules, they're present and won't be reinstalled. But if you deleted some other rules, they'll be installed back, that's why here https://forum.rehips.com/index.php?topic=11838.0 I recommend not to delete rules, but to change them instead.

Thank you very much for the explanation. The better a user understands how some settings work the less risk there is that he or she will not make a mistake.

Based on your explanation, I would like to ask if I remove Firefox's IE and reinstall the default rules would only those rules for Firefox be reinstalled or would reinstalling the default rules (by clicking on the relevant button) also reinstall rules for any other programs that are not working an an IE, but for which I may have changed some settings?

You're right, all settings are copied into isolated environment. And it looks like there are 2 separate Firefox instances: one non-isolated and one isolated, each with its own set of settings.

Why was it done this way? For security purposes. The real settings aren't synced with isolated environment so you could use non-isolated firefox for example for banking and isolated instance has no access to banking settings in case you could have saved something sensitive (though you can resync it by removing isolated environment and reinstalling default rules). And isolated settings aren't synced with real environment as they're treated as compromised and who knows what they contain.
