Cybersecurity threats often bring to mind hackers, malicious software, and external breaches. However, a significant and growing concern for businesses today is the threat posed by insiders—employees, contractors, or partners who have access to an organization's systems, data, and networks. Insider threats can be both intentional and accidental, and they pose unique challenges to businesses of all sizes.
While the risks from external sources are well-known, insider threats are particularly tricky because they exploit trusted access. Luckily, there are solutions businesses can implement to mitigate these risks. Here’s what you need to know!
Common Insider Threats
Accidental Access Sharing
One of the most common cybersecurity risks stemming from insider threats is the accidental sharing of sensitive data. Employees may inadvertently send confidential files via unsecured email, cloud storage links, or other unprotected communication methods. Whether it's sending customer data to the wrong recipient, sharing files without encryption, or uploading sensitive documents to an unsecured cloud platform, these actions can expose your business to data breaches or compliance violations.
For example, an employee might share a file with a colleague who doesn’t have the appropriate clearance, or they could send a document to a personal email account, making it easier for hackers to access. Cybercriminals can take advantage of such human errors to infiltrate a business’s network.
Poor Physical Endpoint Security
Another serious insider threat is poor security for employee devices. This can include leaving laptops, tablets, or smartphones unattended in public spaces, not properly locking devices when not in use, or failing to use secure login methods like multi-factor authentication (MFA).
If an employee’s device is stolen or accessed by an unauthorized individual, all of the business’s sensitive data stored on the device could be exposed. Devices that are not protected by strong passwords, device encryption, or physical locks are particularly vulnerable, as they provide an easy entry point for cybercriminals.
How to Combat Insider Threats
Least Privilege Access
One of the most effective ways to mitigate insider threats is to implement a least privilege access model. This approach ensures that employees and contractors only have access to the systems, data, and applications necessary for them to perform their job functions. By restricting access to sensitive information based on roles, you limit the potential for accidental or intentional misuse of company resources.
Employee Training and Awareness
Since many insider threats result from human error, regular employee training and awareness programs are critical to reducing risks. Employees should be educated about the importance of data security and the potential consequences of accidental file sharing or poor endpoint security practices, as well as best practices and methods that they should be following in order to ensure maximum safety. Reinforcing a security-conscious culture within an organization through this training will also help employees understand their role in protecting the business from cybersecurity threats.
Strong Authentication and Endpoint Security
Ensuring that employee devices are properly secured with strong authentication methods is crucial. Multi-factor authentication (MFA) is a crucial aspect of zero-trust security, and implementing it for all critical systems adds an extra layer of protection against unauthorized access. Furthermore, companies can benefit from strong endpoint security solutions on all devices. This includes encryption to protect data on devices, remote wipe capabilities in case of theft, and endpoint protection software that can detect and prevent unauthorized access to company resources.
User Activity Monitoring
An often-overlooked solution to insider threats is proactive monitoring of user activity. By tracking employee access to sensitive systems and files, businesses can detect unusual or unauthorized activity that may signal a potential threat. This could include monitoring file access logs, tracking email communication for sensitive data, and flagging unauthorized attempts to download or share files. Regular audits and access reviews can also be conducted to assess whether employees still need access to certain data or systems.
