Microsoft making a new feature mandatory requirement for Windows KMS activation

Microsoft has introduced enhancements to its Windows operating system security, including an update to Entra ID authentication with default passkeys and AI-enhanced security updates. A key advancement is the KMS Hardware-Secured initiative, which uses Trusted Platform Module (TPM)-based attestation to ensure KMS hosts operate on trusted hardware for Windows volume activation. This aims to combat risks from counterfeit KMS servers. Under the new model, KMS hosts will confirm their hardware identity using TPM before activating Windows devices. Starting in August 2026, Windows Server 2025 will provide readiness messaging for KMS host compliance with new security requirements. TPM attestation will be mandatory for KMS Hardware-Secured activation with the upcoming Windows Server 2028 LTSC release. Organizations are advised to prepare for this transition.

Psychology says people who use only free version of antivirus aren’t careless: What this choice may reveal

Individuals who choose free antivirus software often do so based on a careful evaluation of their needs, budget constraints, and personal experiences with security. Factors influencing this decision include monthly budget, type of internet usage, trust in software brands, previous experiences with malware, confidence in personal online habits, and awareness of cybersecurity risks. Psychological theories, such as Prospect Theory and Satisficing Theory, suggest that users assess the perceived benefits of free software against the costs of paid options, leading many to conclude that free solutions are sufficient for their needs. Research indicates that technology choices are based on perceived usefulness and value, with positive past experiences reinforcing the decision to continue using free antivirus software. Overall, individuals often make decisions by balancing their requirements with available resources, highlighting the importance of evaluating personal needs before making purchases.

Microsoft Edge 150 Adds Google Account Sign-In on Windows and macOS

Microsoft has introduced the ability to sign into its Edge browser using a Google account, starting with version 150 on Windows and macOS. This feature allows users to integrate their Google accounts alongside Microsoft accounts and is being rolled out gradually. System administrators can manage this feature through the NonMicrosoftAccountSignInEnabled policy, which organizations can enable or disable based on compliance and security needs. Edge 150 is the last version compatible with macOS 12 Monterey, and users are encouraged to upgrade to macOS 13 Ventura or later. The update has transitioned the Workspaces feature to a new architecture but removed the sharing function. Users can sign in to Google accounts by updating to version 150.0.4078.48 or newer and following the sign-in process in Edge Settings.

Microsoft quietly nuked its controversial blog claiming Defender is all you need

Microsoft Defender has evolved from a criticized product to a robust security solution for everyday users. Initially, many recommended third-party antivirus software over Defender due to its inadequacies. Microsoft has improved Defender's built-in protection, making it suitable for a diverse user base. However, users with complex security needs may still benefit from third-party antivirus applications. Recently, Microsoft deleted an article that claimed Defender was sufficient for all users, acknowledging that while it meets basic protection needs, third-party solutions can address more intricate security demands. Microsoft now recognizes the importance of both built-in protection and third-party applications, reflecting a balanced view of user requirements.

Take Control: Customer-Managed Keys for Lakebase Postgres

Encryption at rest is essential for cloud environments, especially in regulated sectors. Lakebase offers Customer Managed Keys (CMK), allowing organizations to control their encryption keys from preferred Key Management Services (KMS) like AWS KMS, Azure Key Vault, or Google Cloud KMS. Lakebase CMK manages both persistent storage and ephemeral compute, ensuring data security. Lakebase's architecture separates storage and compute layers, enabling elastic scaling and serverless operations. The storage layer maintains persistent data, while the compute layer consists of dynamic Postgres instances. This separation poses encryption challenges, addressed by Lakebase CMK through a hierarchical Envelope Encryption model. The key hierarchy includes: 1. Customer Managed Key (CMK): The Root of Trust in the cloud KMS, never accessed in plaintext by Databricks. 2. Key Encryption Key (KEK): A transient key for wrapping data keys. 3. Data Encryption Keys (DEKs): Unique keys for each data segment, stored in an encrypted state. When data access is needed, Lakebase retrieves DEKs by unwrapping keys from the KMS. If a key is revoked, access to the data is denied, and ephemeral compute instances are terminated. In practice, CMK applies to: 1. Persistence Layer (Storage): All data segments are encrypted with keys controlled by the CMK. 2. Ephemeral Layer (Compute): Each compute instance generates a unique ephemeral key, and upon revocation, the instance is terminated, destroying in-memory keys. CMK implementation follows a delegation model, allowing Security Admins to manage keys without accessing data. The process includes key configuration, workspace binding, and lifecycle management. Key rotation is seamless, requiring no data re-encryption. All cryptographic operations involving the CMK are logged by the cloud provider's audit service. Lakebase CMK is available for Enterprise tier customers, allowing organizations to manage their encryption keys effectively.

Databricks Postgres Gets Customer Key Control

Databricks has introduced customer-managed keys (CMK) for its Lakehouse Postgres offering, allowing users to control their data encryption and utilize their own Key Management Service (KMS) from major cloud providers like AWS KMS, Azure Key Vault, or Google Cloud KMS. The Lakehouse Postgres architecture features a hierarchical envelope encryption model with three tiers: the customer-managed root key (CMK), a Key Encryption Key (KEK) used by Databricks' Key Manager Service, and unique Data Encryption Keys (DEKs) for each data segment. If a CMK is revoked, access to the data is denied, and active compute instances are terminated, serving as a failsafe for high-compliance workloads. The implementation allows for granular control over key management and supports seamless key rotation without data re-encryption or downtime. All cryptographic operations are logged within the customer's cloud audit services, available to Databricks Enterprise tier customers.

Microsoft Updates Windows 11 ISO Tool, How To Install It Without A Microsoft Account Or Internet Connection

A clean install of Windows can improve system performance and resolve issues. To begin, back up important files to a NAS, secondary PC, external storage, or cloud service. Wipe the system disk and start fresh. For installing Windows 11, options include performing a Cloud Download reinstall via the Windows Recovery Environment or using external storage with Microsoft's Media Creation Tool or an ISO. Microsoft updates installation ISOs monthly, reducing the need for additional driver installations. Download necessary drivers beforehand, focusing on graphics and chipset drivers. To perform a clean installation, download the latest Windows 11 Disk Image (ISO) from Microsoft's website and use Rufus to write it to external storage. Rufus allows bypassing certain Windows 11 requirements, such as Secure Boot and TPM 2.0, and can facilitate creating a local account instead of using a Microsoft account. Ensure updated BIOS installations are checked if applicable. After writing the installation media, boot from it by accessing the boot menu or adjusting the UEFI setup. During installation, delete existing partitions and select empty space to proceed. Finally, install drivers post-installation.
