Cyber security is the name for the safeguards taken to avoid or reduce any disruption from an attack on data, computers or mobile devices. And, of course, a close correlate is the loss of value. Cyber security is important because government, military, corporate, financial, and medical organizations collect, process, and store unprecedented amounts of data on computers and other devices. Cyber security is NOT implementing a checklist of requirements; rather it is managing cyber risks to an acceptable level. However, numerous studies have revealed that significant vulnerabilities have been found within the software code. It is a critical part of companies that collect and maintain huge databases of customer information, social platforms where personal information are submitted and government organizations where secret, political and defense information are involved. To achieve this goal, we propose (1) a data analysis framework for analyzing the cybercrime underground, (2) CaaS and crimeware definitions, and (3) an associated classification model. Our study It will cover the key cybersecurity concepts of cryptography, cyber forensics and network security in addition to topics such as mobile network security, cloud security, and ethical hacking techniques and tools.
