Application Security - Flask demo

A simple Flask app with Application Security embedded.

Choosing an app

There are two demos found in this repo. They're called env_vars and secrets_manager. The former receives its Application Security keys via environment vairables. The latter retrieves them from AWS Secrets Manager.

Each of their setup instructions can be found below.

env_vars

1. Build the Docker image:

cd code/env_vars
docker build -t <username>/flask-app-sec .

2. Run it:

docker run \
--name flask-app-sec \
-d -p 5000:5000 \
-e TREND_AP_KEY=<AP_KEY> \
-e TREND_AP_SECRET=<AP_SECRET> \
<username>/flask-app-sec

secrets_manager

1. Create a Secrets Manager entry named TrendMicro/ApplicationSecurity. Add two rows named TREND_AP_KEY and TREND_AP_SECRET.

2. Build the Docker image:

cd code/secrets_manager
docker build -t <username>/flask-app-sec .

2. Run it:

docker run \
--name flask-app-sec \
-d -p 5000:5000 \
-e AWS_ACCESS_KEY_ID=<KEY_ID> \
-e AWS_SECRET_ACCESS_KEY=<ACCESS_KEY> \
-e AWS_DEFAULT_REGION=ap-<REGION> \
<username>/flask-app-sec

Debugging

You can add debug outputs by using the -e ENABLE_DEBUGGING=True switch.

Below is an example of the debug output:

Method: POST
Headers:
('Host', '127.0.0.1:5000')
('Connection', 'keep-alive')
('Content-Length', '265')
('Cache-Control', 'max-age=0')
('Origin', 'http://127.0.0.1:5000')
('Upgrade-Insecure-Requests', '1')
('Dnt', '1')
('Content-Type', 'multipart/form-data; boundary=----WebKitFormBoundary8hzXxhZrJjMv0M07')
('User-Agent', 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36')
('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9')

('Accept-Language', 'en-AU,en-GB;q=0.9,en-US;q=0.8,en;q=0.7')
('Cookie', 'MCPopupClosed=yes')

If malicious files are not detected, use the above output to ensure that:

• Method is POST
• Content-Type is multipart/form-data and that boundary= is valid.
