An efficient optimal security system for intrusion detection in cloud computing environment using hybrid deep learning technique

•Improved heap optimization (IHO) removed unwanted data for data quality.•Intrusion detection systems (IDS) for cloud computing environments detected known abnormalities with minimal false alarms.•A chaotic red deer optimization (CRDO) method selected optimal features from many features.•The hybrid deep Kronecker neural network (DKNN) detected cloud intrusions and attacks.
