Minimising Insider Cybersecurity Threats

When it comes to cybersecurity, many organisations tend to concentrate on external threats, often overlooking the risks posed from within.

Insider threats, whether stemming from unintentional employee errors or deliberate malicious actions, are critical to address for maintaining a robust cybersecurity framework.?

In this article we outline essential strategies to effectively prevent and manage these internal cybersecurity risks.?

1. Enhance Cybersecurity Awareness?

Ensuring that everyone in your organization maintains a high level of cybersecurity awareness is vital. Cybersecurity should be embedded into the company culture rather than being treated as a checklist item. To foster this environment, consider:?

• Regularly updating training materials and cybersecurity resources.?

• Consistently enforcing cybersecurity policies when violations occur.?

• Encouraging senior leaders to advocate for and model cybersecurity best practices.?

• Maintaining an open-door policy for employees to discuss cybersecurity concerns.?

2. Recognise Warning Signs?

Being able to identify potential insider threats is crucial. Whether it's an innocent mistake, a disgruntled employee, or someone driven by financial gain, look out for:?

• Actions that inadvertently increase cybersecurity risks, like using personal cloud storage for work files or emailing passwords.?

• Changes in employee behaviour, such as a shift in attitude, declining performance, or altered interactions with colleagues.?

• Signs of financial motivations, including communication with competitors, sudden resignations, attempts to access or download secure files, or notable changes in personal finances.?

3. Monitor File Access?

Utilizing secure cloud storage solutions like Microsoft 365 allows organizations to track and monitor file access effectively. This proactive approach can help prevent potential cybersecurity breaches. Key indicators to watch include:?

• Accessing files at unusual times, especially outside regular work hours.?

• Downloading large amounts of data onto personal devices such as computers or USB drives.?

• Unauthorised attempts to access files beyond assigned privileges and permissions.?

4. Limit Access Based on Need-to-Know?

Implementing a "zero trust" approach is highly effective for reducing the risk of data breaches. This strategy doesn’t reflect distrust towards employees but emphasises restricting access to sensitive data. Only grant permissions on a need-to-know basis and consider temporary access for specific tasks. This method enhances security and protects critical information.?
