This article is concerned with the globally exponentially mean‐square stabilization problem for uncertain disturbed networked switched systems (NSSs) subject to mixed network attacks and multiple asynchronous switching by exploring an optimized event‐triggered scheme. First, we consider a new challenge of multiple asynchronous switching stemmed from the varying switching delays within the event‐triggered scheme and controller. Second, assume that the data transmission network is subject to attacks consisting of deception attacks and aperiodic DoS attacks. Third, an optimized resilient dynamic event‐triggered scheme (ORD‐ETS) with switching behavior and external noises is proposed to intelligently reduce the inessential released data. For further improving the system performance, the updated ORD‐ETS (UORD‐ETS) is designed by introducing some fixed signals‐released points. Then, based on the mode‐dependent multiple Lyapunov functionals, integral inequality, incorporated switching signal technique and proposed asynchronous analysis method, some criteria are attained to ensure the globally exponentially mean‐square stable of the uncertain disturbed NSSs with a weighted H∞$$ {H}_{\infty } $$ performance. Further, the co‐design of the desired controller and the event‐triggered scheme is achieved. Ultimately, a numerical simulation with comparative analysis and a practical simulation are conducted to substantiate the validity of the obtained results. This article investigates the globally exponentially mean‐square stabilization problem for uncertain disturbed networked switched systems, which are affected by mixed network attacks and multiple asynchronous switching. The research explores an optimized event‐triggered scheme and successfully co‐designs the desired controller alongside this scheme. Furthermore, two simulations, along with comparative analyses and a practical application, are conducted to validate the derived results.
