Unseen Predators: The Growing Threat of Insider Attacks in Cybersecurity

Wise old Owl

Explore the growing threat of insider attacks in the realm of cybersecurity. From defining what constitutes an insider threat, its various types, to strategies for mitigating such risks, this comprehensive guide covers all aspects of this pressing issue. Just as an owl maintains constant vigilance, we too must keep a watchful eye on the potential risks within our own


Insider Threats

When it comes to cybersecurity threats, we often visualize hackers in distant locations, plotting attacks behind multiple computer screens. However, one of the most pressing and under-acknowledged dangers lurks much closer to home – insider threats. Just as an owl is a silent observer in the night, these threats often go unnoticed until it's too late.

What are Insider Threats:

An insider threat refers to any security threat that originates from within the organization. This includes employees, former employees, contractors, or business associates who have privileged access to the network system. These individuals, whether maliciously or unintentionally, can cause significant harm to an organization's cybersecurity infrastructure.

The Scope of the Problem:

The rise of insider threats is a growing concern in the cybersecurity landscape. According to a recent study, insider threats have increased by 47% in just two years, costing organizations billions annually. While accidental threats (caused by human error or negligence) are more common, malicious insider threats tend to cause more financial damage.

Here is a great study on Insider Threats conducted by the Ponemon Institute.

Types of Insider Threats:

  1. Negligent insiders: These individuals unintentionally cause security breaches due to lack of awareness or carelessness. For instance, they might click on a phishing link or use weak passwords, exposing the system to external threats.

  2. Malicious insiders: These are individuals who intentionally compromise an organization's security. They could be disgruntled employees seeking revenge, those enticed by financial gain, or spies from competitor companies.

  3. Infiltrators: These are cybercriminals who acquire insider status by gaining unauthorized access to the organization's network. They might use tactics like social engineering or credential theft.

Mitigating Insider Threats:

Mitigating insider threats requires a multi-faceted approach:

  • Culture of Security Awareness: Organizations need to foster a culture of security awareness. Regular training sessions should be conducted to educate employees about potential threats and safe cybersecurity practices.

  • Access Control: Implement the principle of least privilege (PoLP). Ensure that employees have access only to the information they need for their job. Regularly review and update these access privileges.

  • User Activity Monitoring: Use security tools to monitor user activities and detect abnormal behavior. Anomalies might include multiple failed login attempts, access to sensitive data, or unusual working hours.

  • Incident Response Plan: Have a comprehensive incident response plan in place. The faster you can identify and respond to an insider threat, the lesser will be the damage.


Just as an owl keeps a vigilant watch in the night, organizations must maintain constant vigilance over their internal operations. Recognizing the danger of insider threats is the first step towards fortifying your cybersecurity strategy. Through a combination of proactive measures and robust cybersecurity tools, businesses can effectively mitigate the risks posed by insider threats and ensure a secure digital environment.

Remember, the owl is always alert, always watching. In the realm of cybersecurity, we must strive to do the same.
