Windows XP Service Pack 3 fr

Le Service Pack 3 de Microsoft intègre l'ensemble des correctifs / mises à jour sorties jusqu'à aujourd'hui pour Windows XP ainsi que la prise en charge du WPA2 pour la sécurisation des communications Wi-Fi et la prise en charge du NAP (Network Access Protection) qui permet d’isoler les utilisateurs ne se conformant pas aux exigences de sécurité d’un réseau informatique.

Quelques changements du Service Pack 3 :
New Functionality :
- Black Hole Router Detection : SP3's black hole router detection has been significantly improved. Black hole router detection is when a router silently discards data packets. SP3 will turn black hole router detection on by default.

- Network Access Protection : Now, you have heard of Vista's new Network Access Protection(NAP)! Now XP gets it too! NAP is a policy enforcement platform built into Microsoft Windows Vista, Windows Server 2008 (now in beta testing), and Windows XP Service Pack 3 (which includes the NAP Client for Windows XP, now in beta testing) that allows you to better protect network assets by enforcing compliance with system health requirements. With NAP, you can create customized health policies to validate computer health before allowing access or communication, automatically update compliant computers to ensure ongoing compliance, and optionally confine noncompliant computers to a restricted network until they become compliant.

- Credentials Security Service Provider : This is a new Security Service Provider being added in Windows XP Service Pack 3 that is available via the Security Service Provider Interface, for forward compatibility with Windows Vista and Windows Server 2008. CredSSP enables an application to delegate the user’s credentials from the Client to the target Server. The Windows XP Service Pack 3 functionality provides the client-side SSP implementation. It is used by Remote Desktop Protocol 6.0 and is available for use by third party applications as well.

- Descriptive Security Options UI : The Security Options control panel in Windows XP Service Pack 3 now has more descriptive text to explain the settings and prevent incorrect configuration of settings.

- Enhanced security for Administrator and Service policy entries : In System Center Essentials for Windows XP Service Pack 3, Administrators and Service entries will be present by default on any new instance of policy. Additionally, the UI for the "Impersonate Client After Authentication" user right will not be able to remove these settings.

- Microsoft Kernel Mode Cryptographic Module : Windows XP Service Pack 3 includes the implementation of the SHA2 family of hashing algorithms (SHA 256, 384 and 512) and support for the same in X.509 certificate validation. Previously, Windows XP Service Pack2 crypto modules rsaenh.dll, dssenh.dll and fips.sys had been certified according to FIPS 140-1 specifications. FIPS 140-1 standard has been now replaced by FIPS 140-2. These modules have now been validated and certified according to this new standard.

- Windows Product Activation : As in Windows Server 2003 Service Pack 2, and Windows Vista, the user may now complete setup without having to provide their product key. They will be prompted for the product key as part of Genuine Advantage during subsequent use.
