Orphaned users in SQL Server arise when a database user is associated with a login in the master database that no longer exists and should be removed. This situation can happen when the login is removed or when the database is transferred to a different server lacking the corresponding login. The SQL Server logins existing on a server instance can be seen through the sys.server_principals catalog view and the sys.sql_logins compatibility view.

DevOps has already become an integrated part of almost every industry. Whether it’s technology, automotive, healthcare, or any other industry, it’s hard to imagine an organization that doesn’t rely on DevOps. Numbers speak better: the majority of consumers are from the technology sector – 44 %, yet there are a lot of organizations from other industries that depend on DevOps – financial, education, etc.

Secure Boot constitutes a vital component within modern Windows servers and client devices, forming an integral aspect of the Unified Extensible Firmware Interface (UEFI) specification. Its primary function involves the validation of trusted software components during the boot process, thereby fortifying system security against diverse malware and unauthorized software infiltrations.

Anonymous logon refers to a type of network access where a user can log in to a system or network resource without providing any authentication credentials such as a username or password. This type of access is typically granted to allow basic, unauthenticated access to certain resources for public use or for specific purposes.

The “Network access: Restrict clients allowed to make remote calls to SAM” security policy setting manages which users are permitted to view the list of users and groups stored in both the local Security Accounts Manager (SAM) database and Active Directory through remote calls. This policy setting allows you to restrict remote RPC connections to SAM. If not selected, the default security descriptor will be used.

Cipher suites are a set of cryptographic algorithms utilized by the schannel SSP implementation of TLS/SSL protocols. These algorithms are employed to generate keys and encrypt data. Each cipher suite designates specific algorithms for the following functions: In TLS 1.2 and TLS 1.3, the NSA suggests using cryptographic settings that meet the standards in CNSSP 15, known as Commercial National Security Algorithms.

Kernel Direct Memory Access (DMA) Protection is a security feature in Windows designed to prevent unauthorized access to memory by external peripherals. Kernel DMA Protection requires UEFI firmware support, and Virtualization-based Security (VBS) isn’t required. Kernel DMA Protection offers enhanced security measures for the system compared to the countermeasures against BitLocker DMA attacks, all while preserving the usability of external peripherals.
