Implementation of attack(-defense) trees.

Project description

adtrees implements some methods for qualitative and quantitative evaluation of security using attack trees and attack-defense trees.

The package is intended to be used together with the ADTool, but this is not obligatory.

Prerequisites

Optimization problems on attack-defense trees are solved using lp_solve. For the installation of lp_solve, see Using lpsolve from Python. General information on lp_solve can be found here.

No special prerequisites for the remaining functionalities of adtrees.

Installation

pip install adtrees

Example

import adtrees as adt

# initialize attack(-defense) tree from an output file 'tree.xml' produced by the ADTool
T = adt.ADTree('tree.xml')

# create a basic assignment of cost for the basic actions of the defender in T
ba = adt.BasicAssignment()
for b in T.basic_actions('d'):
    ba[b] = 10

# create an instance of the 'maximal coverage' optimization problem
problem = adt.ADTilp(T, costassignment=ba, budget=100, problem='coverage')

# solve the problem
problem.solve()

# the optimal set of countermeasures and some additional information is displayed

For other functionalities and more details, refer to the walk-through examples in examples folder.
