2. Change file /var/www/signtest/settings.py
3. After changing make migrations:
# cd /var/www/signtest/app/ && . venv/bin/activate && python3 manage.py migrate && deactivate
4. Activate the virtual host:
# mv /etc/nginx/conf.d/signtest.conf.disabled /etc/nginx/conf.d/signtest.conf # nginx -t & service nginx reload
5. Make server’s reboot or services’ restart and check their work:

6. For authorization you should create user by command
cd /var/www/signtest/app/ && . venv/bin/activate && python3 manage.py createsuperuser
For possibility of password reset you should enter Email
There are following events, which were got from API and machine learning module on the main page:
BT 11 — the request was detected by signature method as an attack, but according to the «Nemesida AI» module’s decision was unblocked.
BT 12 — the request was blocked by «Nemesida AI» module and wasn’t detected as an attack by signature method.
BT 13 — the request was blocked by «Nemesida AI» module and signature method.
Exported events correct the Nemesida AI’s operation process:
- after the export «False Negative» events will be taken into account as examples of illegitimate request during the current and next training. If the training was finished before the export, it is necessary to make retraining;
- after the export «False Negative» events are taken into account for the current models and the models which will be trained in the future.
If you delete some events, it is necessary to make models’ retraining.
