From: Security risk assessment of projects in high-risk areas based on attack-defense game model
Variables | Definition | Variables | Definition |
|---|---|---|---|
A | Attack Strategies | \(\mu_{{\text{k}}}\) | The prior probability of k types of attackers |
D | Defensive Strategies | \(U_{{\text{a}}}^{{\text{k}}}\) | Expected benefits for k types of attackers |
S | Strategy Set | \(p_{k}\) | Probability of attacker Ak attacking the project |
\(D_{T}\) | Total defensive resources | \(p_{{k^{*} }}\) | Probability of attack on the project under the balanced strategy |
\(S_{A}\)\(S_{D}\) | Attack strategy set and Defensive strategy set | \(P_{D}\) | Vulnerability of the project |
\(A_{k}\) | k types of attackers | L | Losses after the project is attacked |
\(S_{{\text{a}}}^{{\text{k}}}\) | Ak’s strategy set | \(G_{{\text{k}}}\) | The value of the project in the eyes of attacker Ak |
