AppLocker

AppLocker Overview

AppLocker provides policy-based access control management for applications.

To assist you in process analysis, AppLocker captures command information for each process at runtime, and writes that data to the security log and states, ”The system is attempting to launch a process with the following attributes:”

Added functionality to set rules on app packages, which helps manage Windows Store apps. For more information, see Packaged Apps and Packaged App Installer Rules in AppLocker.

BitLocker

BitLocker Overview

For more information, see New and changed functionality.

Introduced in Windows Server 2012.

Group Managed Service Accounts

Group Managed Service Accounts Overview

The group Managed Service Account provides the same functionality as the standalone Managed Service Account within the domain, and it extends that functionality over multiple servers.

No changes.

Added the group Managed Service Account. For more information, see What's New for Managed Service Accounts.

Kerberos

Kerberos Authentication Overview

Kerberos protocol is an authentication mechanism that verifies the identity of a user or host.

Change of behavior when the account is in the Protected User security group.

For more information, see Credentials protection and management.

Reduced authentication failures due to larger service tickets, added changes for developers and IT professionals, changes to smart card sign on KDC validation defaults, and added configuration and maintenance improvements.

Important

For domain-joined devices, the default changed so that now smart card sign-on requires that the KDC certificate chains to a CA in the NTAuth store.

For more information, see What's New in Kerberos Authentication

Local Computer Policy Settings

Security Policy Settings Overview

Security policy settings are the configurable rules that the operating system follows when it determines the permissions to grant in response to a request for access to resources.

Group Policy Administrative Templates can also be used for security management.

The policy setting System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signingwas changed to reflect changes in the BitLocker recovery password process.

For improved process auditing, Audit Process Creation was added to the System node of Administrative Templates under Computer Configuration.

Added new security policies to improve security management. For more information, see New and changed functionality.

NTLM

NTLM Overview

The NTLM authentication protocols are based on a challenge-and-response mechanism that proves to a server or domain controller that a user knows the password associated with an account.

Change of behavior when the account is in the Protected User security group.

For more information, see Protected Users Security Group.

No changes.

Passwords

Passwords Overview

The most common method for authenticating a user's identity is to use a secret passphrase or password as part of the sign-in process.

No changes.

Microsoft offers other means for proving identity. For more information, see Smart Card Overview and Virtual smart cards.

No changes.

Security Auditing

Security Auditing Overview

Security auditing can help identify attacks (successful or not) that pose a threat to your network, or attacks against resources that you have determined are of value through a risk assessment.

No changes.

Added expression-based audit policies, and improvements in the ability to audit new types of securable objects and removable storage devices. For more information, see What's New in Security Auditing.

No changes.

No changes.

Smart Cards

Smart Card Overview

Smart cards provide a tamper-resistant and portable security solution for tasks such as authenticating clients, signing in to domains, signing code, and securing email.

The process to enroll TPM-enabled devices as a virtual smart card device has improved. APIs are added to simplify the enrollment process, making it easier to enroll a device with a virtual smart card regardless of whether they are domain joined and regardless of the hardware.

Changed the smart card sign-in experience, service start and stop behavior, and smart card transactions, by adding support for Windows RT devices and Windows 8 applications. For more information, see What's New in Smart Cards.
