Is there some known good way to make an effective whitelist of applications, |
2 |
which are granted network access? |

4 |
By the way, there is another related question: I remember, I once started |
5 |
googleearth as user1 and had firefox running as user2; really, googleearth |
6 |
opened link into user2's firefox! So I can easily have an illusion of |
7 |
protection such a way (user1 application bypasses firewall by signalling |
8 |
user2 application somehow). |
9 |
What the question really is? How can I know, that particular application can |
10 |
make / accept a dangerous signal (or other interprocess comm.) and how can I |
11 |
forbid that, if necessary? |
