Windows 11 has just announced, despite already being on the market since October , its improvements in cybersecurity. We are going to analyse the new functionalities, some of them old and even known, but applied by default or substantially improved. Of course, the overall strategy had to be based on the fashionable concept of Zero Trust and hybrid work in several layers, and this is how they have organised it. Pluto is a processor solely dedicated to security and is embedded in Qualcomm and AMD Ryzen versions.

That is, a TPM directly in the processor that stores e. What is it for and how does it improve on current TPMs? After all, as complicated as it sounds, it is possible to trap BitLocker passwords by connecting a piece of hardware to the processor and reading this traffic with a certain program.

In fact, during the official presentation of the functionality, there is a quite practical demonstration of the attack process. Indeed, it will be made open source so that it can be used by other operating systems. Config Lock is simple to explain. Using Config Lock, there will be no window of opportunity between the time of a user-perpetrated change to a security setting and the enforcement of the security policy imposed by the administration. If the user disables any security system, it will immediately revert back to the site as configured by the policy designer.

An interesting new feature. It basically encrypts files over BitLocker, with a layer of encryption that is also invisible to the user. But the user does not have to remember or execute anything to decrypt his data but can access the data without any problems when logging in with Hello in Windows.

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.

All of these, despite being already known, will be enabled as standard in Windows Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

Devices accessing the corporate wireless network must also be enrolled in the device-management system. If employees want to use their personal devices to access Microsoft resources, the devices must be enrolled and adhere to the same device-health policies that govern corporate-owned devices.

Virtual Desktop creates a session with a virtual machine that meets the device-management requirements. This allows individuals using unmanaged devices to securely access select Microsoft resources. There is still work remaining within the verify device pillar. In the verify access pillar, our focus is on segmenting users and devices across purpose-built networks, migrating all Microsoft employees to use the internet as the default network, and automatically routing users and devices to appropriate network segments.

We have successfully deployed several network segments, both for users and devices, including the creation of a new internet-default wireless network across all Microsoft buildings.

All users have received policy updates to their systems, thus making this internet-based network their new default. As part of the new wireless network rollout, we also deployed a device-registration portal. This portal allows users to self-identify, register, or modify devices to ensure that the devices connect to the appropriate network segment.

Through this portal, users can register guest devices, user devices, and IoT devices. We have nearly completed the migration of our highest-priority IoT devices in Microsoft offices into the appropriate segments. We still have a lot of work to do within the verify access pillar. For IoT, we need to complete the migration of the remaining high-priority devices in Microsoft offices and then start on high-priority devices in our datacenters.

In the verify services pillar, our efforts center on enabling conditional access across all applications and services. This has the added benefit of eliminating the dependency on VPN and the corporate network.

Our goal is to eliminate the need for VPN and create a seamless experience for accessing corporate resources from the internet. Amid the COVID pandemic, a large percentage of our user population has transitioned to work from home. This shift has provided increased use of remote network connectivity. While we have taken the first steps toward modernizing legacy applications and services that still use VPN, we are in the process of establishing clear plans and timelines for enabling access from the internet.

We also plan to invest in extending the portfolio of applications and services enforcing conditional access beyond Microsoft and VPN. Figure 2 provides a simplified reference architecture for our approach to implementing Zero Trust.

The primary components of this process are Intune for device management and device security policy configuration, Microsoft Azure Active Directory Azure AD conditional access for device health validation, and Azure AD for user and device inventory.

The system works with Intune, by pushing device configuration requirements to the managed devices. The device then generates a statement of health, which is stored in Microsoft Azure AD. When the device user requests access to a resource, the device health state is verified as part of the authentication exchange with Azure AD. Our transition to a Zero Trust model has made significant progress. Each enterprise that adopts Zero Trust will need to determine what approach best suits their unique environment.

This includes balancing risk profiles with access methods, defining the scope for the implementation of Zero Trust in their environments, and determining what specific verifications they want to require for users to gain access to their company resources. In all of this, encouraging the organization-wide embrace of Zero Trust is critical to success, no matter where you decide to begin your transition.
