Insider Threats: The Risk Inside Your Organisation

Introduction

Most companies focus on external hackers. But internal users can also cause serious damage, whether by mistake or intent.

Types of Insider Threats

There are three main types:

▪ Accidental actions (wrong file sent)
▪ Negligent behaviour (weak passwords)
▪ Malicious intent (data theft or sabotage)

Warning Signs

▪ Unusual file downloads
▪ Accessing systems outside normal work hours
▪ Sharing credentials
▪ Trying to reach restricted data

How to Reduce Risk

▪ Limit access based on job roles
▪ Remove access immediately when staff leave
▪ Monitor system activity logs
▪ Train staff regularly on security rules

Conclusion

Insider threats are often overlooked but very real. Strong access control and monitoring reduce the risk significantly.
