Client Hyper-V in Windows 8 Client Hyper-V on Windows 8 provides a rich virtual platform for developers and IT professionals. You can create and manage virtual machines using client Hyper-V leveraging the security, scale, and manageability of Windows 8 and Server Hyper-V platforms. This is a convenient lab and test environment for Wintel Engineers, developers and cloud engineer. Client Hyper-V uses the same VHD format as Hyper-V on the server. However not all the features available in bare-metal Hyper-V are available in Client Hyper-V. Supported Configuration: - Windows 8 32-bit and 64-bit operating systems - Support up to 32 virtual processors and 512GB of memory - Support IDE, iSCSI, SMB, and USB flash drives. - BitLocker Drive Encryption and Secure Boot - Support Second Level Address Translation (SLAT) on x64 PC - Multiple wired and Wireless network support - 3D, audio, multi-touch,sleep and hibernate states - Support same VHD virtual disk as bare-metal Hyper-V You can build, host, and test an entire infrastructure on your Admin PC and then export the virtual machines directly into production environment in Windows Server 2012. To turn on the Windows 8 Hyper-V feature also installs a VM management tool called Hyper-V Manager. - Hover mouse on right hand side top corner, Click Search, Type Control Panel then click control panel click Programs, then select Programs and Features. - Select Turn Windows Features on or off. - Click Hyper-V, then OK, and then Close. To enable Client Hyper-V using Windows PowerShell, Open elevated PowerShell command , type the following: Enable-WindowsOptionalFeature-Online-FeatureName Microsoft-Hyper-V Once Hyper-V is enabled, you must shut down PC and start your PC to complete installation. You will be able to create and manage VMs through Hyper-V Manager or the Hyper-V Module for Windows PowerShell. You can also use Virtual Machine Connection to remotely connect to VMs. You can utilize sysinternals Disk2vhd VHD converter to create and import large virtual machines into Client Hyper-V to test and experiment your infrastructure. Hardening Security of Server- The Bottom Line Securing Servers from internal and external threat is the key aspect of managing and administering Windows Servers. If you carefully design, implement and maintain IT Infrastructure you will have a better night sleep knowing you are safe. There will not be music in the ears of oncall Engineer facing nightmare. So how you accomplish a tight security and control on IT infrastructure without compromising work environment. Here are some tips for you. Infrastructure Firewalls You must have an isolated Head Office network from branch office. You can purchase MPLS or IP WAN service from your ISP. Alternatively you can create site to site VPN using security appliance or application like Forefront TMG 2010. A better design approach would be a multi-tier firewall so that your internal server, DMZ servers and branch servers stay securely connected. You can have specific VLANs for specific servers/services/applications with correct Access Control List (ACL) in Cisco switches and routers. This will add another layer of firewall to the network. Computer based Firewalls In Windows Server 2008 and Windows Server 2012, there is built in firewall. You can configure that built-in firewall for a group of servers or individual server to provide host based firewall. Both Server 2008 and Server 2012 shipped with advanced Firewall and security configuration tools which you can administer through Group Policy object. Intrusion Detection System Another key aspect of firewall is security appliance that provide you to harden security using Intrusion Detection System (IDS) /Intrusion Protection System (IPS). These are third-party Devices or appliance. The IDS helps you monitor network traffic, logs data about the traffic, analyses the traffic based on signatures and anomalies, recognizes potential attacks, and alerts the IT staff to the perceived attack. The IPS does all that, but it also has the capability to react to the perceived attack. IPS is also capable of reacting to an attack based on your configured rules. Server Hardening- The bottom line You execute the following action to stop being hacked or take these actions to prevent hacking - Isolate Administrator Role for individual tasks similar to their job description. - Stopping and disabling all unnecessary services and applications - Renaming the Administrator account - Implement password policy using Default Domain Policy in Group Policy Object - Implement GPO to secure servers and clients - Deleting or disabling all unnecessary user accounts - Use of Service Account to run services and application instead of running services using IT Admin’s generic account and store password to safe location - Create Role Based User Account instead of using user account by user name - Requiring strong authentication and certificates to access applications - Performing regular firmware, operating system and application updates using WSUS or SCCM - Installing renowned Antivirus and Anti-Spyware program and manage them centrally - Document all system configurations and store these documents in safe location - Audit and monitor IT infrastructure regularly to prevent any misconfiguration - Use Read only Domain Controller (RODC) for branch office - Utilize great benefit of Server Core Technology reducing surface attack further - Utilize NPS, NAP and Certificate Servers to secure access to applications and services.

Klijent Hyper-V u sustavu Windows 8 Klijent Hyper-V u sustavu Windows 8 pruža bogat virtualnu platformu za programere i IT profesionalcima. Možete stvoriti i upravljati virtualnim strojevima pomoću klijenta Hyper-V utjecati na sigurnost, ljestvica, i upravljivost sustava Windows 8 i Server Hyper-V platforme. To je zgodan laboratorij i test okruženje za Wintel inženjera, developera i cloud inženjer. Klijent Hyper-V koristi isti VHD format kao Hyper-V na poslužitelju. Međutim nisu sve značajke dostupne u goli-metal Hyper-V su dostupni u klijent Hyper-V. Podržano Konfiguracija: - Windows 8 32-bitni i 64-bitni operacijski sustavi - Potpora do 32 virtualnih procesora i memorije 512GB - Podrška IDE, iSCSI, Sambu, i USB flash pogoni. - BitLocker šifriranje pogona i Secure Boot - Podrška Drugi prijevod razine (letva) Adresa na x64 računalu - Višestruki ožičen i bežične mreže podrške - 3D, audio, multi-touch, spavanje i hibernacija države - Podrška isti VHD virtualni disk kao goli-metal Hyper-V Možete izgraditi, domaćin, i testirati cijelu infrastrukturu na vašem računalu Admin, a zatim izvoz virtualnih strojeva izravno u proizvodnom okruženju u sustavu Windows Server 2012. Za uključivanje Windows 8 Hyper-V značajka također instalira VM alat za upravljanje zove Hyper-V Manager. - Zadržite miš na desnoj strani gornjem kutu, kliknite Traži, ploča Vid Upravljačka zatim Upravljačka ploča Programi kliknite, a zatim odaberite Programi i značajke. - Odaberite Uključiti značajki sustava Windows ili isključiti. - Kliknite Hyper-V, onda u redu, a zatim Zatvori. Da biste omogućili klijenta Hyper-V u sustavu Windows PowerShell, Otvoreno povišen PowerShell naredbe, upišite sljedeće: Omogućiti-WindowsOptionalFeature-Online-FeatureName Microsoft-Hyper-V Nakon Hyper-V je omogućena, morate isključiti računalo i pokrenite računalo da biste dovršili instalaciju. Vi ćete biti u stanju stvoriti i upravljati VMS kroz Hyper-V Manager ili Hyper-V modul za Windows PowerShell. Također možete koristiti Virtual Connection Machine za udaljeno povezivanje VM. Možete koristiti Sysinternals Disk2vhd VHD konverter za stvaranje i uvesti velike virtualnih strojeva u klijentu Hyper-V za testiranje i eksperimentirati svoju infrastrukturu.
