Common Threats refers to the catalog of frequently encountered dangers that can compromise the confidentiality, integrity, or availability of information systems and data. These threats represent the predictable risks that organizations face, ranging from malware infections to social engineering attacks. Understanding common threats allows security professionals to proactively implement defenses and establish robust security policies. For instance, recognizing phishing as a common threat enables the deployment of user awareness training and email filtering solutions. This concept is distinct from specific vulnerabilities, which are the weaknesses that threats exploit. Knowledge of common threats is essential for cybersecurity certifications like CompTIA Security+ and CySA+, as well as advanced exams such as CISSP.
