Abstract EN
The cyberphysical system (CPS) is becoming the infrastructure of society.
Unfortunately, the CPS is vulnerable to cyberattacks, which may cause environmental pollution, property losses, and even casualties.
Furthermore, in contrast to the conventional Internet, the devices in CPSs are more specific, and the device systems may not be upgraded or installed with new programs during their life spans.
The selection of the best defense nodes for defeating cyberattacks is quite challenging in CPSs.
To overcome this issue, several attack-defense modeled methods have been proposed.
However, few existing studies have considered the defense cost, which is usually a determinant in practice.
In this paper, we propose a method for choosing optimal defense nodes that (1) can defeat specific attacks and (2) are inexpensive.
First, the atom attack defense tree (A2DTree) is proposed by adding constraints to the conventional attack defense tree (ADTree).
Second, the algebraic method is used to efficiently calculate the minimum defense cost.
On this basis, a minimum defense cost calculation tool is designed and implemented.
Finally, the effectiveness of the proposed method is verified with two typical case studies, and a comparative experiment of related work is carried out.
The results show that the method can correctly and efficiently identify the optimal defense nodes and calculate the minimum defense cost of a CPS.
