Omogućite ili onemogućite Credential Guard u sustavu Windows 10:  ^{(Enable or Disable Credential Guard in Windows 10: )}Windows Credential Guard koristi sigurnost temeljenu na virtualizaciji kako bi izolirao tajne tako da im samo privilegirani softver sustava može pristupiti. Neovlašteni pristup tim tajnama može dovesti do napada krađe vjerodajnica, kao što su Pass-the-Hash ili Pass-The-Ticket . Windows Credential Guard sprječava ove napade štiteći NTLM hashove lozinki, Kerberos ulaznice za dodjelu tiketa^{(Kerberos Ticket Granting Tickets)} i vjerodajnice koje aplikacije pohranjuju kao vjerodajnice domene.

Omogućavanjem Windows Credential Guard-a osiguravaju se sljedeće značajke i rješenja:^{(By enabling Windows Credential Guard the following features and solutions are provided:)}

Sigurnost hardvera Sigurnost ^{(Hardware security)}
temeljena na virtualizaciji ^{(Virtualization-based security)}
Bolja zaštita od naprednih trajnih prijetnji^{(Better protection against advanced persistent threats)}

Sada znate važnost Credential Guard -a , svakako biste to trebali omogućiti za svoj sustav. Dakle, bez gubljenja vremena, pogledajmo kako omogućiti ili onemogućiti Credential Guard^{(Disable Credential Guard)} u sustavu Windows 10^{(Windows 10)} uz pomoć dolje navedenog vodiča.

Omogućite ili onemogućite Credential Guard u sustavu Windows 10^{(Windows 10)}

Obavezno  stvorite točku vraćanja^{(create a restore point)}  u slučaju da nešto pođe po zlu.

Metoda 1: Omogućite ili onemogućite Credential Guard u sustavu Windows 10 pomoću uređivača pravila grupe^{(Method 1: Enable or Disable Credential Guard in Windows 10 using Group Policy Editor)}

Metoda 2: Omogućite ili onemogućite Credential Guard u sustavu Windows 10 pomoću uređivača registra^{(Method 2: Enable or Disable Credential Guard in Windows 10 using Registry Editor)}

Credential Guard koristi sigurnosne značajke temeljene na virtualizaciji koje se prvo moraju omogućiti iz značajke Windows prije nego što možete omogućiti ili onemogućiti Credential Guard u uređivaču registra^{(Registry Editor)} . Za omogućavanje sigurnosnih značajki temeljenih na virtualizaciji koristite samo jednu od dolje navedenih metoda .^(Make)

Dodajte sigurnosne značajke temeljene na virtualizaciji pomoću programa i značajki^{(Add the virtualization-based security features by using Programs and Features)}

1. Pritisnite tipku Windows + R zatim upišite appwiz.cpl i pritisnite Enter da otvorite Program i značajke.^{(Program and Features.)}

Enable or Disable Credential Guard in Windows 10

Enable or Disable Credential Guard in Windows 10: Windows Credential Guard uses virtualization-based security to isolate secrets so that only privileged system software can access them. Unauthorized access to these secrets can lead to credential theft attacks, such as Pass-the-Hash or Pass-The-Ticket. Windows Credential Guard prevents these attacks by protecting NTLM password hashes, Kerberos Ticket Granting Tickets, and credentials stored by applications as domain credentials.

By enabling Windows Credential Guard the following features and solutions are provided:

Hardware security
Virtualization-based security
Better protection against advanced persistent threats

Now you know the importance of the Credential Guard, you should definitely enable this for your system. So without wasting any time let’s see How to Enable or Disable Credential Guard in Windows 10 with the help of the below-listed tutorial.
