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.

Top 10 Best Antivirus Software for Windows 11 in 2026

In 2026, leading antivirus software for Windows 11 includes Bitdefender, Norton, Kaspersky, and McAfee, known for robust malware protection and real-time scanning. While Microsoft Defender is included with Windows 11, third-party antivirus solutions offer advanced features like ransomware protection, VPN access, and improved privacy controls. For gamers, Bitdefender and Norton provide specialized gaming modes that reduce interruptions while maintaining strong threat protection. Free antivirus programs offer basic protection but lack the advanced features and higher detection rates of paid options. Key factors for selecting antivirus software include malware protection effectiveness, system performance impact, pricing, additional features, ease of use, and compatibility with devices.

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.

Epic Games brings Secure Boot and TPM to competitive Fortnite — most players unaffected by new measures

Epic Games has mandated enhanced security measures for participation in all Fortnite tournaments, requiring players to enable TPM, Secure Boot, and virtualization-based security. This follows a previous requirement for FNCS events, which necessitated an account level of 350 or higher. The company is focused on maintaining fairness in the game and has taken legal action against cheating, including lawsuits against those selling cheats and stolen accounts. Players must ensure their systems meet these security requirements to compete in tournaments.

Microsoft Adds Centralized RDP Shortpath Control via GPO and Intune

Microsoft has enhanced the management of Remote Desktop Protocol (RDP) Shortpath, now available through Group Policy Objects (GPO) and Microsoft Intune, allowing IT teams to implement centralized control over RDP Shortpath behavior across Azure Virtual Desktop (AVD) session hosts and Windows 365 Cloud PCs. RDP Shortpath improves performance and reliability by establishing a direct, UDP-based network connection, reducing latency and enhancing responsiveness for audio and video applications. Prior to this update, managing RDP Shortpath was fragmented, requiring manual adjustments on individual session hosts, which complicated consistent networking behavior. The new centralized configuration allows administrators to enforce Shortpath settings uniformly, reducing administrative overhead and ensuring consistent performance and security controls. Administrators can manage RDP Shortpath settings centrally, control all Shortpath modes, and ensure compatibility with AVD host pool settings. Effective operation of RDP Shortpath requires appropriate network conditions, and policy changes necessitate a restart of session hosts or Cloud PCs.
