Cybercrime on local and state governments is continuing to rise, as cybercriminals understand the government possesses lots of data and information that are vital and highly classified. The risks to these federal IT systems are increasing, with insider threats from witting or unwitting employees, escalating threats from around the globe, and the emergence of new more destructive attacks. The U.S. Government Accountability Office reports that over 35,000 security incidents were reported by federal executive branch civilian agencies to the Department of Homeland Security in fiscal year 2017.

Here we will introduce how to implement a regular cycle of monitoring, maintenance and updating.
