The statistic that around 80 percent of computer security incidents result from "insider" attacks reflects the significant threats posed by employees who have access to sensitive information and systems. This high percentage emphasizes the vulnerabilities that organizations face from within, as these insiders often know the system architecture, security protocols, and how to exploit weaknesses.

Insider threats can manifest in various forms, including malicious actions by disgruntled employees, misuse of access privileges by employees who may be unaware of the repercussions, or even unintentional actions that lead to security breaches. The potential for insider threats is exacerbated by the trust placed in employees, making it crucial for organizations to implement robust access controls, monitoring systems, and continuous training to mitigate these risks.

Understanding that such a large proportion of incidents can be attributed to insiders highlights the necessity of fostering a strong security culture within the organization and actively managing employee behavior to prevent security breaches. This statistic serves as a wake-up call for businesses to focus not only on external threats but also on the potential hazards that their own employees may pose.
