Blocking *CHIP-Installer.exe

FormerMember over 4 years ago

Hallo zusammen,

ich würde auf unserer UTM gerne jeglichen Download von *CHIP-Installer.exe blockieren. Wie bzw. mit welcher Funktion mache ich das am besten?

Du musst über den Webfilter folgende URL sperren: https://www.chip.de/n_downloader/

Da es eine HTTPS Verbindung ist, solltest du den HTTPS Scan aktivieren und einrichten (erfordert ein wenig Know-How aufgrund des zu verteilenden Zertifikats)

Gruß,

Jonas

HTTPS-Scan ist bei uns aktiv.

Habe nun mal https://www.chip.de/n_downloader/ unter Webfilter > Richtlinien unter "Diese Websites blockieren" hinzugefügt. Kann aber immernoch z.B. unter https://www.chip.de/downloads/Tor-Browser_22479695.html den CHIP-Download ausführen....

Das ist grundsätzlich so bei Zertifikaten, dass diese auslaufen :-)

Diese müssen dann neu erstellt/ersetzt werden

Habs grad wieder auf "Nur URL-Filterung" zurückgestellt - hab nicht an die Nicht-AD-Geräte gedacht :-( Wie verfahre ich mit diesen?

Über MMC die Zertifikate auf den NICHT-AD Clients das Zertifikat händisch in den Bereich "Vertrauenswürdige Zertifizierungsstellen" hinzufügen

Alternativ ein eigenes Webfilter Profil für die NICHT-AD Clients erstellen, wo nur die URL-Filterung gilt.

geht auch über das Userportal die über das iPhone aufgerufen wird, sofern keine MDM Software eingesetzt wird:

Ich hab auch mal irgendwo gelesen, dass man den iPhone-Usern direkt nen Link zum Zertifikat schicken kann, welchen die aufrufen sobald der User im hausinternen Netz ist...

Finde aber die Seite nicht mehr :-(

Genau das hab ich gesucht....

Unter https://community.sophos.com/kb/en-us/126895 wird beschrieben "How to trust the Root Certificate" - Aber auf iOS 12.4.1 trifft das nicht zu....

Gibt es eine aktuellere Beschreibung?

My iPhone Xs is on 12.4.1 and that KB article correctly describes what I see.

Hi Bob,

when I open the link on my iPhone first appears a query, if I want to allow it to load the configuration profile. So far so good - I confirm the question with "allow"...
Afterwards a message appears, that the profile was loaded successfully.

But when I navigate to the Settings> General> About> Certificate Trust Settings unfortunately, I have no entry to enable the Root Certificates...

It's been awhile, but I think I installed the CA from the User Portal. How did you do it?

Have you tried deleting the cert from your phone and then loading it via the User Portal?

Hi Bob,

no, I do not like to do it via the user portal but directly via the link passthrough.fw-notify.net/cacert.pem
