## About
|
|
|
|
open-appsec is a machine learning security engine that preemptively and automatically prevent threats against Web Application & APIs.
|
|
|
|
<strong>open-appsec Attachments</strong> connect between processes that provide HTTP data and the <strong>open-appsec Agent</strong> security logic.
|
|
|
|
An attachment gets HTTP data (URL, Header, Body, Response) from a hosting process and delivers it to an open-appsec process known as HTTP Transaction handler.
|
|
|
|
To deal with potential issues where the HTTP Transaction handler process is not responding, the Attachment implements a retry mechanism and configurable fail-open/fail-close mechanism.
|
|
|
|
This repository will host Attachment for different platforms. The first one is the open-appsec attachment for NGINX, implemented as a standard NGINX dynamically loadable module (plugin).

## open-appsec NGINX attachment compilation instructions
|
|
*We Provide an Example for compilation instructions on alpine, the attachment can be complied on other environments that match the environment hosting nginx, yet compilation instructions could need adjustments*
|
|
|
|
The attachment can be compiled to support an existing nginx server or an nginx/ingress-nginxdocker.
|
|
|
|
Your compilation environment must contain git, docker, cmake and g++.
|
|
|
|
Before compiling, ensure the latest development versions of the following libraries:
|
|
|
|
* PCRE
|
|
* libxml2
|
|
* zlib
|
|
* OpenSSL
|
|
* Geoip
|
|
* Python3
|
|
|
|
```bash
|
|
$ apk update
|
|
$ apk add pcre-dev libxml2-dev zlib-dev openssl-dev geoip-dev linux-headers python3
|
|
```
|
|
|
|
### Compiling the attachment code for an existing nginx server
|
|
|
|
On your existing nginx server:
|
|
1. Run command to extract nginx compilation flags to a file
|
|
|
|
```bash
|
|
$ nginx -V &> /tmp/nginx.ver
|
|
```
|
|
|
|
On your compilation environment:
|
|
1. Clone this repository
|
|
2. Copy the file created on your nginx server (the previous section) to your compilation environment to the path /tmp/nginx.ver
|
|
3. Run Configuration script
|
|
4. Run CMake command
|
|
5. Run make command
|
|
|
|
```bash
|
|
$ git clone https://github.com/openappsec/attachment.git
|
|
$ ./attachments/nginx/ngx_module/nginx_version_configuration.sh --conf /tmp/nginx.ver build_out
|
|
$ cmake -DCMAKE_INSTALL_PREFIX=build_out .
|
|
$ make install
|
|
```
|
|
|
|
#### NGINX plugin associated libraries
|
|
The NGINX plugin uses these libraries: shmem_ipc, compression_utils, and nginx_attachment_util.
