Five insiders who threaten your security

When it comes to security threats, we often focus on the risk posed by unknown parties attempting to gain access to information from the outside. However, trusted individuals within an organization can be just as dangerous. Here are five insiders that pose a risk to security — and how to prevent them from bringing harm to your organization.
- Absent-minded employees — Without even thinking, employees can accidentally expose an organization to security threats. Some of the most common ways this can happen is when an employee clicks on a suspicious link, email or attachment, or when sensitive information is sent to a personal email or cloud service, a malware-infected mobile device is connected to the network or a work device is misplaced.
- Revenge seekers — Former or current employees out for revenge sometimes steal or destroy sensitive data. This type of attack is hard to detect, because employee actions aren’t always tracked — especially when an employee has legitimate access to the data.
- Privilege abusers — Misuse of roles and responsibilities can allow employees to do or access things that aren’t required to do their job. Again, a lack of tracking makes this kind of attack hard to detect.
- Partners in crime — Legitimate third-party contractors or other service providers have been responsible for breaches through malware or stolen credentials. Perpetrators in these attacks can be difficult to identify, and the more people who have access to the network, the harder it gets.
- Colluders — Although it doesn’t happen often, trusted employees sometimes work with outside criminals to execute data breaches through means such as creating a security vulnerability, which can be exploited by an outsider.
The steps for fighting internal threats are very similar to the steps for fighting external ones. To protect your organization, follow these tips from Trustwave.
- Conduct thorough risk assessments, including assessments of vendors.
- Have strong policies, anti-malware solutions, data loss prevention solutions and incident response plans in place.
- Take the risk posed by personal devices and cloud services connecting to the network seriously.
- Conduct regular security training sessions and test employees on their understanding of them.
- Use threat management to spot network anomalies.
Security threats don’t always come from the outside. Take these steps to keep your organization secure — inside and out.
