As more companies and organizations continue to shift their operations online and store crucial data electronically, the exposure of their information to cyber threats becomes even higher. The upward trend in the use of Information, Communication, and Technology (ICT) has led to the creation of major cybersecurity risks and openings. Unfortunate incidences have such as hacking the information, communication, and infrastructure networks of several organizations have continued to pose serious risks to organizations. Hacker and intruders nowadays have the equipment and means with which they can penetrate an organization’s information systems using the easiest methods. This work brings out various internet security threats: in fact, it casts light on the numerous internet security threats as viewed by business enterprises. It also examines the preventive approaches and methods for improving security to counter these risks. In this particular study, the researchers conducted a systematic review of secondary sources, to establish how organizations should acquire and implement IT security management tools that are consistent with best practice. They pointed out that this has been made possible through the use of a particular framework called the Security Incident Event Management (SIEM) framework. SIEM tools have significant benefits as a source of data for the security analysts, who can hence effectively respond to the threats more efficiently.
