Alter Table Attestation For Free

ALTER TABLE - ALTER/MODIFY DATATYPE SQL Server / MS Access: ALTER TABLE table_name. ALTER COLUMN column_name datatype; My SQL / Oracle (prior version 10G): ALTER TABLE table_name. MODIFY COLUMN column_name datatype; Oracle 10G and later: ALTER TABLE table_name. MODIFY column_name datatype;

We'd like to convert some varchar columns to support unicode, so since the v12 upgrade, this seems to be the most straightforward approach: ALTER TABLE table1 ALTER COLUMN column1 nvarchar(max) NULL WITH (ONLINE=ON); ALTER TABLE table1 ALTER COLUMN column2 nvarchar(max) NULL WITH (ONLINE=ON);

There are two types of attestation: Local Attestation and Remote Attestation. Local attestation is used when two TEEs run on the same physical machine and remote attestation is used when a user attests a TEE running on a remote physical machine.

An enclave is a protected memory region that provides confidentiality for data and code execution. It's an instance of a Trusted Execution Environment (TEE) which is secured by hardware.

Secure enclave attestation Enclave attestation allows a client application to establish trust with the secure enclave for the database, the application is connected to, before the app uses the enclave for processing sensitive data.

Overview. The Secure Enclave is a dedicated secure subsystem integrated into Apple systems on chip (SoCs). The Secure Enclave is isolated from the main processor to provide an extra layer of security and is designed to keep sensitive user data secure even when the Application Processor kernel becomes compromised.

A Secure Enclave (also known as Trusted Execution Environment) refers to a computing environment that provides isolation for code and data from the operating system using either hardware-based isolation or isolating an entire virtual machine by placing the hypervisor within the Trusted Computing Base (TCB).

Always Encrypted protects the confidentiality of sensitive data and Always Encrypted with secure enclaves expands confidential computing capabilities of Always Encrypted by enabling in-place encryption and richer confidential queries.

Attestation is the process of demonstrating that a software executable has been properly instantiated on a platform. Attestation allows a remote party to gain confidence that the intended software is securely running within an enclave on a fully patched, Intel SGX enabled platform.
