This page describes the architecture, the individual components, and the workflow of the Protegrity Application Protector (AP) solution.

Architecture and Workflow

The following figure illustrates the deployment architecture of the Application Protector (AP).

The following table describes the components of the AP deployment architecture.

Component	Description
Customer Application	Built in supported programming languages and integrates with AP for data protection.
Application Protector	Core protection engine that enforces security policies and performs data protection operations.
Configuration File (config.ini)	Contains initialization parameters passed to AP during startup.
Native Interface	Native interface between AP and the C layer. .Net: Platform Invocation Services (P/Invoke)
Package Enforcement and Deployment	Downloads policy packages from the RP Agent and executes protection operations, such as, protect, unprotect, and reprotect.
Log Forwarder	Collects logs from AP and forwards them to the Audit Store for centralized auditing.
Resilient Package (RP) Agent	Standalone process that retrieves policy packages from ESA and shares them with AP processes using shared memory IPC.

The following steps describe the workflow of a sample AP deployment in the production environment.

System Requirements

The following table lists the minimum hardware configurations.

Hardware Component	Configuration Details
CPU	Depends on the application.
Disk Space	Under 200 MB - including LogForwarder, RP Agent, and AP Java, AP Python or AP .Net.
RAM	Memory usage depends on the AP flavor and application behavior. Refer to AP .Net

Note: The Disk Space depends on the policy size and stored logs on the disk.

Preparing the Environment

The Protegrity Application Protector (AP) .NET provides APIs that integrate with customer applications to protect and unprotect sensitive data. It is compatible with applications developed using .NET Core and C#.

Caution: Install only one environment at a time either production or development. Do not install Mock AP .Net protector in a Production environment.

Preparing the Environment for AP .Net Installation on Windows in a Production Environment

Before installing Protegrity Application Protector (AP) .Net on a Windows platform in a Production environment, ensure the following prerequisites are met:

Extracting the AP .Net Setup Scripts and Package

To extract the setup scripts and package:

Download the ApplicationProtector_WIN-ALL-64_x86-64_NET-STD-2.0-64_<version>.zip file to any location on the machine where you want to install the protector.
Extract the contents of the ApplicationProtector_WIN-ALL-64_x86-64_NET-STD-2.0-64_<version>.zip file.
The following setup files are extracted:
- ApplicationProtector_WIN-ALL-64_x86-64_NET-STD-2.0-64_<version>.zip
- signatures/ApplicationProtector_WIN-ALL-64_x86-64_NET-STD-2.0-64_<version>.zip_10.0.sig
Verify the digital signature of the signed AP .Net build.
For more information about verifying the signed AP .Net build, refer to Verification of Signed Protector Build.
Extract the contents of the AP .Net installation package again.
The following setup files are extracted:
- LogforwarderSetup_Windows_x64_<version>.exe
- RPAgentSetup_Windows_x64_<version>.exe
- APDotNetSetup_Windows_x64_<version>.exe
- APDotNetMockSetup_Windows_x64_<version>.exe
