Day 17: Trust, But Verify

"Trust is like glass. Once it's broken, it's hard to repair."

Let's face it: countless individuals are concerned about external dangers like virus attacks, phishing schemes, and hackers, whether they are individuals browsing the internet or businesses handling essential data. However, what if I told you that some of the most severe risks might be at your home, place of business, or even right next to you? Yes, today we're discussing Insider Threats. The trustworthy individuals who may unintentionally (or, worse, willfully) bring harm.

But don't worry—before you start side-eyeing your colleagues or family members, let’s explore insider threats and how to safeguard against them!


What Are Insider Threats?

An insider threat is a risk created by individuals within an organization or home who have access to vital systems or sensitive data and either unintentionally or intentionally corrupt it. This can occur when employees, contractors, business partners, or even family members use shared devices.

Types of Insider Threats

  1. Unintentional Threats: These are innocent mistakes users make, like accidentally sharing confidential information or clicking on a malicious link.

  2. Malicious Insider Threats: These individuals purposely harm an organization by stealing data or disrupting operations for personal gain or revenge.

  3. Third-Party Insider Threats: Partners, vendors, or service providers with access to your systems or data but lack proper security protocols.

How Insider Threats Happen

  • Weak Password Practices: Sharing passwords, creating basic or repeated passwords.
  • Phishing: Phishing attacks can target even insiders, allowing bad actors to gain access unwittingly.
  • Device Misuse: Using personal devices for work or sharing company devices with family members.
  • Disgruntled Employees: Employee unhappiness can result in insider threats such as data theft or sabotage.

How to Recognize Insider Threats

Here's how to identify potential insider threats, whether you're running a small business or keeping your family's electronics safe:

  1. Unusual Behavior: A rapid shift in an employee's or user's attitude, repeated policy infractions, or accessing data outside their regular job.

  2. Accessing Unauthorized Data: This is a red flag if someone routinely accesses files or directories that they should not.

  3. Data Transfers during odd hours: Large amounts of data exchanged outside regular business hours may signal something odd.

  4. Regular use of external drives: Avoid using USB devices or external storage unnecessarily, especially when there is no real need.


Mitigating Insider Threats

  1. Regular cybersecurity training is crucial for all employees and family members. It prevents unintentional mistakes and ensures a comprehensive understanding of the importance of cybersecurity.

  2. Implement robust access control to restrict access to sensitive information to only those who need it, such as employees or family members who need to access shared files.

  3. Monitoring user behavior can help businesses identify anomalies before they become threats, while at home, it's crucial to prevent children's accidental exposure to potential risks.

  4. Strong Authentication, such as two-factor authentication (2FA) or multi-factor authentication (MFA), can limit access even if credentials are compromised.

  5. Regularly update systems and ensure proper device security with passwords and encryption.

Conclusion: Trust, But Verify

Insider threats can happen anywhere—at work, school, or home. By understanding the warning signs and taking proactive steps, you can mitigate these risks and maintain a safe, secure online and offline environment.

As always, cybersecurity is everyone’s responsibility, and by raising awareness about insider threats, we can Secure Our World together.
