Insider Threats for Remote Teams

The biggest security risk may not be a hacker — it could be a disgruntled employee, a careless contractor, or a compromised credential. Insider threats are the hardest to detect and the most damaging.

Three Types of Insider Threats

Malicious Insider

High

Intentionally steals data, sabotages systems, or sells access. Often a disgruntled employee, someone about to leave, or an employee bribed by competitors.

Warning signs: Accessing data outside their role, downloading large amounts of data, working unusual hours, expressing dissatisfaction

Negligent Insider

Medium-High

Accidentally exposes data through carelessness — weak passwords, phishing clicks, unsecured devices, sharing files incorrectly. The most common insider threat type.

Warning signs: Ignoring security policies, using personal devices without protection, clicking phishing links, sharing credentials

Compromised Insider

High

An employee whose credentials are stolen by an external attacker. The attacker uses the legitimate credentials to access data, appearing as a normal employee.

Warning signs: Logins from unusual locations, access at unusual times, accessing data outside normal patterns

Prevention for Remote Teams

Least Privilege Access

Each person should only have access to data they need for their role. Review permissions quarterly. Remove access when roles change.

Strong Authentication

MFA on all accounts. Passkeys or hardware keys for sensitive systems. Password manager required. No shared credentials.

VPN + Encryption

VPN on all remote connections. Full-disk encryption on all devices. Encrypted cloud storage for sensitive files.

Offboarding Procedures

When someone leaves: revoke all access immediately, change shared passwords, recover company devices, audit their recent data access.

Security Culture

Regular training on phishing and social engineering. Clear security policies. Encourage reporting of suspicious behavior without blame.

Audit Logs

Log who accesses what, when. Review unusual patterns. Don't surveil — but do maintain visibility into data access.
