Sichere Konfiguration

Allgemein

Sicherheitskonzepte

Beispiel Apache Konfiguration

--Debian apache 2.4 -enable mod_headers sudo a2enmod headers -insert into config file: sudo vi /etc/apache2/conf-available/security.conf -enable XFO Header set X-Frame-Options: "sameorigin" -enable CSP Header set Content-Security-Policy: "object-src 'self'; frame-src 'self'; script-src 'self‘;" -X-Content-Type-Options Header set X-Content-Type-Options: „no sniff“ -Config for port 80 (redirect to https) sudo a2enmod rewrite -in Virtual Hosts file: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} </IfModule> -Config for port 443 -enable SSL, e.g. SSLEngine On SSLCertificateFile /etc/ssl/localcerts/apache.pem SSLCertificateKeyFile /etc/ssl/localcerts/apache.key

Lokale Installation

how to install observatory (tested on Ubuntu 16.04 LTS)

sudo apt-get install -y git libpq-dev postgresql redis-server python3 python3-pip
cd /opt/
sudo git clone https://github.com/mozilla/http-observatory.git
sudo su - postgres
createdb http_observatory
psql http_observatory < /opt/http-observatory/httpobs/database/schema.sql
psql http_observatory
\password httpobsapi #passwort festlegen z.B. its
\password httpobsscanner #passwort festlegen z.B. its

exit db (\q)exit psql user (exit)

sudo vi /etc/postgresql/9.5/main/postgresql.conf #set max_connections = 512, shared_buffers = 256MB
sudo service postgresql restart
sudo useradd -m httpobs
sudo su - httpobs
cd /opt/http-observatory
pip3 install .
pip3 install -r requirements.txt --upgrade
exit

everything from here has to be done for every start - Starting from normal userstart scanner

sudo install -m 750 -o httpobs -g httpobs -d /var/run/httpobs /var/log/httpobs
sudo su - httpobs
echo export HTTPOBS_API_URL="http://localhost:57001/api/v1" >> ~/.profile
cd /opt/http-observatory/
HTTPOBS_DATABASE_USER="httpobsscanner" HTTPOBS_DATABASE_PASS="its" /opt/http-observatory/httpobs/scripts/httpobs-scan-worker

open new Terminal to start api

sudo su - httpobs
cd /opt/http-observatory/
HTTPOBS_DATABASE_USER="httpobsapi" HTTPOBS_DATABASE_PASS="its" uwsgi --http :57001 --wsgi-file /opt/http-observatory/httpobs/website/main.py --processes 8 
--callable app --master

Verwendung der API

Aufruf zum Scannen einer neuene Seite starten
- POST-Request
- http://localhost:57001/api/v1/analyze?host=www.testseite.de
  - hidden=true&rescan=true

Status eines Scans anzeigen
- GET-Request
- http://localhost:57001/api/v1/analyze?host=www.testseite.de

Beispiel für Resultat eines Scans

The tests object contains one test object for each test conducted by the HTTP Observatory. Each test object is contains the following values:

expectation: the expectation for a test result going in
name: the name of the test; this should be the same as the parent object's name
output: artifacts related to the test; these can vary widely between tests and are not guaranteed to be stable over time.
- data: generally as close to the raw output of the test as is possible. For example, in the strict-transport-security test, output -> data contains the raw Strict-Transport-Security header
- ????: other values under output have keys that vary; for example, the strict-transport-security test has a includeSubDomains key that is either set to True or False. Similarly, the redirection test contains a route key that contains an array of the URLs that were redirected to. See example below for more available keys.
pass: whether the test passed or failed; a test that meets or exceeds the expectation will be marked as passed
result: result of the test
score_description: short description describing what result means
score_modifier: how much the result of the test affected the final score; should range between +5 and -50
