Insider Threats 101: How They Work and What You Can Do to Combat Them

As the field of cyber security continues to evolve, one area that remains of great concern for businesses is that of insider threats. Insider threats, employee risks, internal cybersecurity—these concepts dominate the thoughts of every enterprise trying to defend its fortresses. If your business is renting out mission-critical infrastructure like firewalls, servers, and routers, you must work even harder to mitigate insider threats. So, let’s explore what insider threats are, threats, how to recognize them, and most of all, how to defend against them.

What are Insider Threats?

Insider threats are the specific threats an organization incurs because individuals within the organization abuse their legitimate access to the organization’s assets in a manner that can cause harm to the organization. Unlike cyber attacks executed by external actors, insiders are all too legitimate users, and are thus difficult to detect and control.

Complexity of Insider Threats

• They usually contain other trusted peoples.
• They can be both malicious and accidental.
• Their acts could lead to huge loss of data integrity and business reputation.

Types of Insider Threats

The first step to building effective defenses against insider threats is understanding the different types of insider threats. We can classify them into malicious insiders and accidental insiders.

Malicious Insiders

These are known internal actors who are deliberately looking to do harm. Their reasons range from profit to personal retribution.

• Disgruntled employees: Employees who are dissatisfied with their positions or their management team can leak data or sabotage their company’s operations.
• Corporate spies: These insiders steal sensitive information with an eye toward competitive advantage or financial gain.

Accidental Insiders

These threats aren’t malicious; they’re negligent or uninformed:

• Human error: Errors such as emailing the wrong person or setting values incorrectly can put data at risk.
• Negligent actions: Weak passwords, falling victim to phishing attacks and similar behaviors are also considered insider threats.

Early Warning Signs

Detecting insider threats early saves businesses but from great damage. Here are some habits and patterns to look for:

• Database access patterns that are abnormal: An employee accessing data or systems at unusual hours.
• Behavioral changes : Sudden disinterest in work, raising grievance against the organization.
• Data transfer: Large amounts of data being sent to personal email accounts or uploaded to external devices.
• Over-permissioned: Employees that ask for higher privileges without a business case.

Defense Mechanisms

Insider threat defenses must be approached strategically and systemically. Here’s how companies can construct a strong defense:

Implement Access Controls

• Building on least privilege principle: Limit the access employees have to only what they need to do their job.
• Regular Audits: Periodically review access logs and permission levels

Promote a Culture of Security

• Employee Training: Train personnel consistently the significance of security measures and identifying phishing attempts.
• Promote reporting: Encourage employees to report suspicious activity without fear of being penalised.

Leverage Technology

• Monitoring systems: Software that keeps an eye on behaviors that deviate and data transfers.
• Data encryption: Use encryption on sensitive data so that even if information leaks, it’s not accessible to unauthorized persons.

Create an Insider Threat Program

• Team assignment: Assign a team to insider threat detection and response.
• Plan of action: Develop a clear plan of action to take if an insider threat is ever detected.

Conclusion

Resolving insider threats, employee risks, internal cybersecurity is not just an IT issue, but rather a fundamental business priority — arguably, even more so for the companies that rent critical technology infrastructure. These steps implemented could dramatically decrease the risk of insider harm. Furthermore, as outside threats continue to change, so too are the tactics of insider abuses.

Protecting your business is not just a one-time task; it’s an ongoing process. With this knowledge, you can construct a fortress impenetrable even to insiders.
