This is a recent research by security specialists of the Dolos Group to determine if an attacker can access the organisation network from a stolen device and also perform lateral network movement.They were handed a Levovo Laptop preconfigured with the standard security stack for this organization. No prior information about the laptop, test credentials, configuration details, etc were given. They stated it was a 100% blackbox test.Once the got hold of the device, they headed straight to work and performed some reconnaissance of the laptop (BIOS settings, normal boot operation, hardware details, etc) and noted a lot of best practices were being followed, negating many common attacks. For example:Pcileech/DMA attacks were blocked because Intel’s VT-d BIOS setting was enabled. All BIOS settings were locked with a password. The BIOS boot order was locked to prevent booting from USB or CD. Secureboot was fully enabled and prevented any non-signed operating systems. Kon-boot auth bypass did
In Veeam Backup & Replication version 12 and later, the default database system is PostgreSQL, replacing the previously used Microsoft SQL Server Express Edition. This change enables users to leverage the PostgreSQL database as part of the default installation. Veeam supports PostgreSQL from version 14 and above.12.1 release notes still only show 15.x as supported. Also, Veeam Backup & Replication does not support PostgreSQL installations on cloud database services (for example, Amazon Relational Database Service (RDS). Here is a discussion also around this topic. PostgreSQL is a powerful, open-source object-relational database system with active development that has earned it a strong reputation for reliability, feature robustness, and performance.Why has Veeam Switch to Postgre as the Default Database?This decision to switch to PostgreSQL was made due to the limitation associated with Microsft SQL Express edition in terms of scaling (eg max 10 GB Database size). See the Sys
