Vista Security Features

Here are the most significant new features:

** The real Administrator account is disabled by default
** User Account Control prompts users in the Administrators group for an additional confirmation before every administrative task
** Even the Administrator cannot directly overwrite files in the \Windows and \System32 folders. They have to take ownership first, and add the correct permissions
** Internet Explorer 7 runs in Protected Mode by default, which will stop many “drive-by” download attacks
** Address Space Layout Randomization will randomly place critical Windows functions and applications in 1 of 256 places in memory, making many types of buffer overflows significantly harder to pull off
** BitLocker allows one or more drive volumes to be encrypted, and protected with an encryption key that can be stored locally, on a cryptographic chip on the motherboard, or on a USB key
** LM password hashes are disabled by default (finally!) as are LM and NTLMv1 authentication protocols
** Windows Firewall is enabled by default, protects better at boot-up, is integrated with IPSec, and has outbound blocking
** Firewall rules can be applied to specific users, computers, or groups
** Windows Defender is installed by default
** Password-protected screensaver is installed and made active by default
** Over 800 new group policy settings
** You can set multiple user or group-specific Local Security policies
** Session isolation (i.e. Windows kernel services and user-mode programs run in different Windows sessions) will prevent most “shatter”-style attacks
** Services now have SIDs, which simplifies setting security permissions. All default services have been given least-privilege permissions, and are limited by firewall security domain protection
** Portable media devices (such as USB flash memory, CD-ROMs, etc.) can be controlled with read, write, and execute permissions, both per user and per computer
** Integrity levels have been assigned to all files and objects. A security principal must meet or exceed the target resource’s integrity level in order to modify it; regardless of the NTFS permissions
** There are dozens of new log files, all collected in the expanded Event Viewer. Event triggers can be created on any event, and events can be collected to centralized computers
** Transactional NTFS ensures that NTFS changes will be written completely before being made permanent
** Previous Versions client is installed by default, allowing users to self-recover accidentally deleted or modified files
** System Restore now backs up user’s My Documents folder
** Creator Owners now no longer automatically get Full Control permissions, if you don’t want them to
** Commonly manipulated folder and registry keys are virtualized so that malicious modifications don’t result in system-wide infections
** EFS supports smart cards, can encrypt the page file, and has proactive key archival
** Remote Desktop Protocol (RDP) supports strong authentication with digital certificates
** Internet Explorer 7 has an anti-phishing filter and is more resistant to malicious attacks, spyware, and add-on abuse
** Internet Information Service 7 supports more granular loading of code. IIS is no longer a single monolithic executable
** Two more network domain profiles to plan firewall and IPSec rules around
** IPv6 and IPv4 are turned on by default
** Improved wireless security. Now, GPOs and logon scripts can be accomplished through wireless logons
** Improved SMB (file and printer sharing) protocol. Anonymous null session connections are no longer the great threat they once were

Thanks for the comprehensive post from the InfoWorld article. It explains a lot and helps us (well me anyway) to understand Vista security better. I notice the author said further:

In preparing my most recent book, Windows Vista Security: Securing Vista Against Malicious Attacks (Wiley), co-authored with Dr. Jesper Johansson, I’ve counted more than 180 new security improvements and features in Vista. I’ve been developing a PowerPoint presentation on it, and it’s already exceeded 220 slides (and I’m only a third of the way done).

Whew That's a lot of security.
