3. Suspicious User Accounts

Discovering suspicious user accounts on your website is a red flag and a sign of a security breach.

Here's what to look out for:

• New user accounts that were not created by your team or through the normal sign-up processes. This means that attackers have gained access to your system.
• Accounts accessed at odd hours or performing actions that don't align with their role. This might be an attacker exploiting a compromised account.

Security software helps your website by monitoring for suspicious activity and potential threats.

• Pay attention to the specifics of each alert. Common alerts include unusual login attempts, detected viruses, or security breaches.
• You may consider every alert. But remember, not every security notification is a true threat. Investigate the context and frequency of an alert to determine if it is a false positive.
