What is the file extension for Sentinel? ›

Sentinel policies are single files that end in the . sentinel file extension. There is currently no built-in mechanism to Sentinel for merging multiple files. This is purposefully done to make Sentinel policies easy to submit to systems that support Sentinel policies.

Sentinel allows customers to implement policy-as-code in the same way that Terraform implements infrastructure-as-code (IaC). It helps to solve the industry problem with regards to infrastructure standards when utilising IaC, ensuring consistency and compliance of developed configurations.

Imports enable a Sentinel policy to access reusable libraries and external data and functions. Anyone can write their own custom import. Imports are what enable Sentinel policies to do more than look at only local context for making policy decisions. Sentinel also comes with a set of standard imports.

The Sentinel integration with Terraform runs within HCP Terraform and Terraform Enterprise after a terraform plan and before a terraform apply . The policies have access to the created plan, the state at the time of the plan, and the configuration at the time of the plan.

The Sentinel-SAFE format is a specific variation of the Standard Archive Format for Europe (SAFE) format specification designed for the Sentinel satellite products. It is based on the XML Formatted Data Units (XFDU) standard under development by the Consultative Committee for Space Data Systems (CCSDS).

The Sentinel-SAFE format wraps a folder containing image data in a binary data format and product metadata in XML. This flexibility allows the format to be scalable enough to represent all levels of Sentinel products. A Sentinel product refers to a directory folder that contains a collection of information.

OPA is an open-source policy as code tool that can be used across the cloud-native stack, whereas Hashicorps Sentinel is limited to use with Terraform and products in the Hashicorp stack.

Microsoft Sentinel allows you to create custom workbooks across your data. Microsoft Sentinel also comes with built-in workbook templates to allow you to quickly gain insights across your data as soon as you connect a data source. Workbooks are intended for SOC engineers and analysts of all tiers to visualize data.

Instead, you can use HashiCorp Sentinel, a policy as code framework, to automatically enforce compliance and governance policies before Terraform makes infrastructure changes.

In computer programming, a sentinel value (also referred to as a flag value, trip value, rogue value, signal value, or dummy data) is a special value in the context of an algorithm which uses its presence as a condition of termination, typically in a loop or recursive algorithm.

How does sentinel collect data? ›

Microsoft Sentinel can use agents provided by the Azure Monitor service (on which Microsoft Sentinel is based) to collect data from any data source that can perform real-time log streaming. For example, most on-premises data sources connect by using agent-based integration.

While Microsoft Sentinel is accessible in both the Microsoft Defender and Azure portals, Microsoft Sentinel data is stored in Azure regions.

The workflows of Terraform are built on top of five key steps: Write, Init, Plan, Apply, and Destroy. Nevertheless, their details and actions vary between workflows.

Every resource that is managed by Terraform has a lifecycle, this lifecycle contains three stages; Apply (Create), Update, and Destroy.

All Sentinel-2 data are freely available from the Copernicus Data Space Environment. All Sentinel-2 data are freely available from the Copernicus Data Space Environment. Users can download the data via https://dataspace.copernicus.eu/.

The Installable File System (IFS) is a filesystem API in MS-DOS/PC DOS 4. x, IBM OS/2 and Microsoft Windows that enables the operating system to recognize and load drivers for file systems.

ADT files are AUDIT report files which contain information about the issues found during AUDIT process. They can be deleted.
