You might feel confident that your business is safeguarded from external cyber risks with the latest security solutions. However, have you considered how well-protected you are against internal threats?
Whether intentional or accidental, employees, vendors, partners, and even business owners can all pose risks to your organisation. This is why it’s essential to implement strategies to defend your business from within. In this article, we’ll explore different types of insider threats, how to recognise warning signs, and, most importantly, how to prevent them.
Common Types of Insider Threats
Insider threats come in various forms, each presenting unique risks to your organisation. Below are some of the most common ones:
Data Theft
This occurs when a staff member or associated individual steals or leaks sensitive information for personal benefit or malicious intent. This can include physically stealing devices that contain sensitive information or copying data digitally.
Example: An employee at a leading healthcare provider downloads and sells protected patient data on the dark web.
Sabotage
This involves a disgruntled employee, activist, or someone acting on behalf of a competitor who intentionally disrupts or damages company operations. This might be done by deleting critical files, infecting devices, or locking a business out of its systems by changing passwords.
Example: A disgruntled staff member at a café tampers with machinery, causing breakdowns and a subsequent loss of business.
Unauthorised Access
This is a security breach where malicious insiders or employees access confidential information without permission. It could also occur accidentally if individuals unknowingly gain access to sensitive data.
Example: A disgruntled employee uses their credentials to view and leak privileged information to competitors.
Negligence and Human Error
Both negligence and errors can lead to insider threats. While training can reduce errors, negligence requires more stringent policies and enforcement.
Example: An employee clicks on a malicious link, downloading malware onto the network, or misplaces a laptop containing sensitive data, putting the company’s information at risk.
Credential Sharing
Sharing your login credentials is like giving someone the keys to your home—you never know what they might do. Similarly, sharing your passwords with colleagues increases the risk of data breaches and cyberattacks.
Example: An employee uses a friend’s device to check work emails, forgets to log out, and the device is later compromised, exposing the company’s confidential data.
How to Identify Insider Threats
It’s important to be vigilant and recognise the warning signs early. Watch out for these red flags:
- Unusual Access Patterns: An employee suddenly starts viewing sensitive company information unrelated to their role.
- Large Data Transfers: A sudden increase in data downloads, especially onto external storage devices.
- Frequent Access Requests: Someone repeatedly requests access to business-critical data that doesn’t pertain to their responsibilities.
- Use of Unauthorised Devices: Confidential data being accessed via personal devices.
- Disabled Security Measures: Instances where an employee deactivates security tools, such as firewalls or antivirus software.
- Behavioural Shifts: A worker exhibits unusual behaviour, such as consistently missing deadlines or showing signs of stress.
Strengthen Your Defences
Here are five essential steps for creating a robust cybersecurity strategy that will keep your business secure:
- Enforce Strong Password Policies and promote multi-factor authentication wherever possible.
- Limit Data Access: Ensure staff can only access the information necessary for their roles, and regularly review access rights.
- Educate Employees: Provide training on insider threats and reinforce security best practices.
- Backup Critical Data: Regularly back up important data to minimise the impact of any data loss incident.
- Create an Incident Response Plan: Develop a clear plan outlining how to respond to insider threat incidents.
