A　large　amount　of　data　that　IoT　applications　deal,　is　users’　Private　data,　and　their　privacy　is　a　significant　issue.　However,　if　users　are　not　sure　about　the　security　of　their　data,　they　will　not　desire　to　use　such　applications.　The　goal　of　this　study　is　to　improve　the　security　and　privacy　of　users　in　the　Internet　of　Things　(IoTs)　setting.　Since,　the　application　of　IoT　technology　is　growing　day　by　day.　Also,　the　importance　of　users’　data　security　is　always　top　of　the　list　and　difficult　to　achieve.　In　this　study,　we　studied　latest　development　in　the　security　of　Internet　of　Things　(IoTs)　so　that　we　can　use　it　to　investigate　its　challenges　and　advantages.　©　2021,　Springer　Nature　Switzerland　AG.
