Attack graphs illustrate ways in which an adversary can exploit vulnerabilities to break into a system. System administrators evaluate attack graphs to find where their system’s weaknesses might be and to decide which security measures should be taken in order to defend their systems.
Our product helps security administrators reason about the risk posed to the various system components and to evaluate adversarial and defense strategies when signs of compromise have been found. For the future, this tool should be made available to anyone who wants to monitor and solve network vulnerability issues.
To install the dependecies:
apt-get install libboost-all-dev -y
apt-get install libpcap-dev -y
apt-get install libpq-dev -y
sudo python3 setup.py install
make
npm install
cd database && python3 load.py -r
Run tests:
make test
sudo python3 setup.py test
The inference engine depends on mulval. Please follow the instructions for installation from here. To run the inference engine, you need to set the following path variables: (in case they are not set, the module will try some default paths)
MULVALROOT=<mulval_path>
XSB_DIR=<xsb_path>
The package needs elevated privileges as it runs the NIC in promiscuous mode.
Running a master node:
sudo python3 service.py master
Running a slave node:
sudo python3 service.py slave [master-ip]
Package options:
usage: service.py [-h] [-m MASTER] [-p PORT] [-i INTERFACE] [-s SIMULATION]
[-f FILTER] [-v] [-b] [-t BATCH_THREADS]
type
positional arguments:
type The type of node run: 'master' or 'slave'
optional arguments:
-h, --help show this help message and exit
-m MASTER, --master MASTER
Specify master IP for connecting a slave.
-p PORT, --port PORT Specify port for runnning a slave.
-i INTERFACE, --interface INTERFACE
The network interface listened to.
-s SIMULATION, --simulation SIMULATION
To run a simulated network from a network
configuration file use this flag.
-f FILTER, --filter FILTER
Specify a mask for filtering the packets. (e.g.
'10.1.1.1/16' would keep packets starting with '10.1')
-v, --verbose Set the logging level to DEBUG.
-b, --benchmark Disables database and inference engine for
benchmarking.
-t BATCH_THREADS, --batch_threads BATCH_THREADS
Number of threads that should run host discovery. (default is single-threaded)
Running on a simulated network:
sudo python3 service.py master -s [simulation-config]
The configuration files for the simulated network should be placed inside the folder simulation/confs. The simulation module looks only for the files inside simulation/confs. For an example configuration see simulation/confs/simple.json:
sudo python3 service.py master -s simple.json
Once the main application is running you can try to use individual component using interactive Python cli:
python3 service/cli.py
CLI options:
-h, --help show this help message and exit
--echo ECHO [ECHO ...]
Usual echo command.
--exit Exit.
--quit Exit.
--gen Send a request to the inference engine.
--vul VUL VUL Send a request to the database service for a
vulnerability. The first argument is the product. The
second argument is the version.
--priv PRIV PRIV Send a request to the database service for privilege
level escalation for a vulnerability. The first
argument is the product. The second argument is the
version. (e.g. `priv windows_2000 *`)
--graph Send a request to the local graph service.
--packet Send a request to the local sniffer service.
To run benchmarks:
sudo python3 simulation/benchmarks.py
The simulations are run on random overlay topologies with fixed number of nodes and edges. Random packets get generated whenever the simulation module connection gets a call within a fixed timeout of 0.5 seconds, whereas the scans are generated within a timeout of 3 seconds.
Results of the simulations can be found in the folder simulation/res and were generated on a single machine.
