METHODS AND SYSTEMS PROVIDING CYBER SECURITY

Methods and systems for providing cyber security, wherein a computer with network access incorporates game theory and utilizes a honeypot to enhance game-theoretic developments over active and passive sensors. To numerically solve the uniquely three-sided game modeled cyber security problem, using a geometric solution based on three-dimensional (3D) action surface and action curve. The methods and systems determine whether the game problem has one Nash equilibrium, multiple Nash equilibriums, or no Nash equilibrium; checks whether the equilibrium is a mixed or pure Nash; and timely computes Nash equilibriums; and follows a fictitious play concept. The solution is adaptive and can be applied for any partially observed cyber security system.
