Day-one security features Take advantage of key security features—turned on by default. Massively reduce malware Security features reduce by 60 percent in tested devices. One place to go Manage security and your cloud through one control pane. If the user has not logged into Windows with Hello, the files will be encrypted and cannot be accessed.

What is this for? As the example in the presentation says, it prevents attacks that bypass the lock screen through direct access attacks to unprotected DMA memory. The PDE password is not known to the user, it is simply erased from memory when the system is locked and decrypted when unlocked with the usual login. It would also serve as additional security if the attacker bypasses BitLocker. It seems to clash or overlap somewhat with the EFS functionality.

How is this implemented? If the attacker tries to log in without being authenticated as a user by bypassing the lock screen or mounting the disk on another computer , a closed lock would appear on the files and a message prohibiting access would appear. SAC seems very much oriented towards checking the signature and certificates of the manufacturer of the binaries.

It will try to determine if it is correct with its valid and correct certificate , before even going through Windows Defender to add an extra layer of security. SAC is AI-based, which implies telemetry.

Microsoft seems to be moving towards requiring by default that programs are signed or downloaded from a trusted repository, as MacOS or Android already do.

It improves the usual SmartScreen where Windows, thanks to its telemetry, tells you whether an app is legitimate or not. It also improves AppLocker which is more static. SAC will be based on AI hosted in the cloud, learning from the user. In fact, for those who want to activate it, it requires a reinstallation of the system so that it can learn from the beginning what programs are common on that computer.

This is perhaps one of the most interesting measures. SmartScreen has so far, via the browser or in professional versions, by other means protected the system from a malicious URL, or a suspicious domain. Just for the sake of comparison. Now it goes further, and Windows protects passwords on several levels, always watching where they are used or sent. On the one hand, it observes the network connections in any application including Teams and if it concludes that the password travels to a domain that it should not, it alerts the user, even if it is not the main URL of the domain being visited.

The image shows how a page pretending to be the Office login embedded in TEAMS is actually the connection is highlighted in the Fiddler sniffer carrying the Office password to another domain. However, it goes further. If you happen to store passwords in a TXT file in Notepad, you will be alerted to the error. Even worse, if you reuse a password known to the operating system in the picture, for example, on LinkedIn , it will also alert you to the problem it could pose.

This way, Windows as an operating system does not treat the password as just another string but knows it at all levels and monitors it throughout its use within the operating system. Could it lead to false positives with password storage apps? Windows 11 also enables by default VBS, or virtualisation as a security feature.

It focuses on virtualising memory to isolate processes from each other as much as possible. If an attacker tries to exploit a flaw in the kernel and is operating from there, an even higher or lower, depending on how you look at it abstraction with even more power than the kernel would be available, which would allow preventing processes or access to certain resources even when the attacker already has powers in the ring0. Hence its usefulness. This is implemented with hypervisor-protected code integrity HVCI which would prevent injecting dynamic code into the kernel as Wannacry did.

In turn, this will allow the Credential Guard not new, but underutilised and LSASS protection to work directly, so that it does not load unsigned code into this crucial process, which is also an old acquaintance RunAsPPL in the registry, basically a protection against Mimikatz.
