Insider Threats

Many times, the real threat is not external but internal. While you're defending against external threats and even the best private email service you might use, you can't ignore internal threats.

Unintentional insider threats are just that unintentional. But that doesn't mean they have no consequences. In fact, an unwary employee could potentially cost their company millions or more by replying to malicious emails and leaking important company documents.

On the other hand, insider threats can also be entirely intentional. For example, a fired former employee can still access your company's database. This angry ex-employee can happily enter and destroy your company database) to retaliate against your company and cause severe damage.

How to address threats

When considering email security threats, most people care about the money hackers can steal directly from them. But that's just the tip of the iceberg.

For example, don't download potentially malicious attachments from unknown sources, and don't leak sensitive information to untrusted entities.

On a personal level, email security starts with strong passwords (supported via two-factor authentication or 2FA). Creating a password that is not easily brute-forced is critical to keeping your account secure. In other words, you should not use weak and short passwords (e.g., "123hki"). Conversely, a strong, long password (e.g., "guDvoj-pemmi8-davryp") is much more secure than a short, weak password.

Beyond that, every organization, be it a small business or a large corporation, should invest in IT security, including anti-virus and anti-phishing software, to protect themselves, their employees, and customers from malicious attacks.
