External cyberattacks often dominate conversations about business protection and data safety. But what about the risks inside your walls? Insider threats are the most overlooked yet dangerous vulnerabilities that businesses face. Whether they stem from malicious motives or simple negligence, these threats can jeopardize your company’s data, finances, and reputation.
The good news? Learning how to prevent insider threats is achievable with proactive measures and the right mindset. Read on to discover how to shield your business effectively.
Types of Insider Threats to Watch For
An insider threat is an individual within your company who misuses their access in a way that compromises security. These individuals could be employees, contractors, or even vendors with inside knowledge of your operations. Typically, there are three main types to keep an eye out for:
Malicious Insiders
Malicious insiders may act out of financial motivation, revenge, or personal gain. For example, a disgruntled employee who thinks they’re overdue for a promotion could leak company secrets out of spite. These threats are often premeditated.
Negligent Insiders
Employees who ignore or forget security policies can also create vulnerabilities, even if they don’t have ill intent. Maybe an older staff member uses a personal USB drive on their work computer and brings sensitive data home. Or perhaps a new hire isn’t aware of the company’s password policies and chooses an easy-to-guess password.
These employees who don’t understand how to prevent insider threats can inadvertently cause harm to the company’s data and reputation.
Compromised Insiders
Sometimes, the employees themselves aren’t the real culprits. Accounts hijacked through phishing scams or malware can allow outsiders to gain unauthorized access.
Common Red Flags and Risk Factors
Insider threats are very preventable—once you understand the risk factors and warning signs, you’ll understand exactly how to prevent insider threats. Here are some red flags and behaviors that require special attention:
- Employees with excessive access to sensitive data outside their job scope.
- Unusual login patterns, like login attempts after hours or from uncommon locations.
- Downloading or emailing extensive volumes of proprietary data.
- Sudden behavioral changes resulting in disciplinary issues, unexplained frustration, or job dissatisfaction.
How to Protect Your Business: 6 Key Strategies
If any of those red flags sound familiar, you need to act now to protect your business. So, how do you prevent insider threats? Here are six key strategies to safeguard your company’s sensitive data and prevent internal attacks.
1. Implement Least Privilege Access Controls
Give employees limited access to company data—they only need the information necessary for their specific roles. If an employee changes roles or leaves the organization, update their access immediately.
2. Use Multi-Factor Authentication (MFA) and Strong Password Policies
MFA adds an extra security layer, even if passwords are compromised, so it doesn’t hurt to implement this protection tool. Meanwhile, enforce regular password updates and encourage employees to use complex combinations. You could also have an IT specialist demonstrate how easy it is to hack simple passwords and the requirements for a strong one.
3. Deploy Monitoring and Threat Detection Tools
Invest in tools that track user activity and identify anomalies in real-time. Solutions like user behavior analytics (UBA) can detect irregular patterns and alert your team to unusual behavior.
4. Conduct Regular Security Awareness Training
Educate your team on phishing schemes, social engineering tactics, and proper data management. An informed employee is your first line of defense against many insider threats. If they understand how to prevent insider threats, they’ll do most of the work for you.
5. Create a Culture of Security and Reporting
Focus on creating an environment where employees feel comfortable reporting suspicious activity without fearing backlash. If your workers are afraid of repercussions, they may hesitate to report a potential threat. Encourage open communication and reward employees who follow proper security protocols and report any suspicious behavior.
6. Have an Insider Threat Incident Response Plan
Be ready to react quickly if a breach occurs. Your incident response plan should detail how to contain and investigate the breach to minimize damage.
