How to Beef up Your Business’ Email Security

Inside threats to email security are much greater than outside threats. Verizon recently investigated the problem, and found that 50 percent of incidents are caused by people inside the organization.

Your business’ confidentiality, availability of information and integrity are compromised by worker negligence, when employees send sensitive company or client information to the wrong people, or dispose of medical and personal data improperly.

Other security incidents are comprised of what’s considered “misuse events,” when employees steal information or profit from data that your company owns.

Here’s how to minimize your organization’s internal email threats and maintain the integrity of your network’s security.

Vet employees

Require your employees to undergo a background check upon beginning their employment with your company. Don’t forget to require your third-party vendors to perform the same checks with their employees. This step will help you weed out criminals and potential workers with malicious intentions.

Offboard effectively

As soon as an employee leaves the company, deactivate all passwords they use to mitigate the risk of a disgruntled worker stealing or sharing confidential data.

Monitor third-party contractors

If your company has even just one relationship with a third-party vendor, you’ll need to closely evaluate and monitor these interactions. Keep a close eye on passwords and access, and have a plan in place to swiftly revoke these when the relationship concludes.

Conduct training

Education goes a long way toward helping employees understand the potential risks that result from their actions. Create an IT security training program and conduct education classes quarterly, bi-annually, or annually. Include factors like how phishing works, using strong passwords, and other potential security threats.

Generate a BYOD policy

The best way to mitigate the risks of internal email threats is to create a bring-your-own-device policy. Assemble a team to discuss the needs and solutions, and then share the document with your employees. Everyone should understand how to use their personal mobile devices with company documents, such as what they can email or download. If you’re going to allow employees to use their personal devices, consider paying for and requiring them to use monitoring and encrypting services so they can safely access the company email platform and network.

Create necessary policies

A common way that email is compromised happens when employees upload or download applications and software. Create a policy that strictly regulates these activities to prevent problems.

Watch file-sharing

Control employee use of personal file-sharing services for confidential company information. For example, they should not store sensitive information or passwords on services like OneNote, DropBox or Google Drive. Always reset an employee’s password on these platforms when they leave the company or are terminated. You don’t want a former employee to access this information once they leave your company.

Your company’s email services are a source of security vulnerability. Make sure you take these steps to protecting sensitive company information and data, and you’ll avoid having to deal with problems.
