Instruction: Sophos Firewall admin account locked after multiple failed attempts

Explanation: AI-generated knowledge about Sophos Firewall admin account locked after multiple failed attempts

Output:
According to the Sophos Firewall documentation, when an administrator attempts to log in with an incorrect password multiple times, the firewall will lock the admin account to prevent further unauthorized access.

This is done to prevent brute-force attacks and protect the system from being compromised. The exact phrase used in the Sophos Firewall documentation is: "Account locked after 5 failed login attempts."

However, it's worth noting that this behavior can be customized or overridden through Sophos Firewall configuration options. For example, the firewall can be configured to use a different number of failed login attempts before locking the account, or to allow a specific amount of time between failed login attempts.

In addition, Sophos Firewall has features like two-factor authentication (2FA) and multi-factor authentication (MFA) that can be enabled to add an extra layer of security to the admin account. These features can be used to prevent unauthorized access to the system even in case of a brute-force attack.

It's also worth noting that if the admin account is locked, the only way to regain access is by contacting Sophos support or following the proper procedures for unlocking the account.

In terms of preventing this scenario from happening in the first place, Sophos Firewall recommends implementing strong password policies, enabling 2FA or MFA, and regularly reviewing and updating system configurations to ensure that they are secure and up-to-date.

Here is an example of how this might be configured in Sophos Central:

1.  Go to **Settings** > **Account Settings** > **Admin Accounts**
2.  Click on the **Lockout Settings** tab
3.  Set the number of failed login attempts before locking the account (e.g., 5)
4.  Set the amount of time between failed login attempts (e.g., 1 minute)

By following these steps and enabling additional security features like 2FA or MFA, administrators can significantly reduce the risk of their admin account being compromised due to brute-force attacks.

In case of an admin account lockout, the recommended course of action is to contact Sophos support for assistance in unlocking the account.
