Common Mistakes

Using port 21 which is for FTP and not secure.

Using port 8080 which is often for HTTP but not secure.

Using port 3306 which is for MySQL database connections.

Port 443 is the standard port for secure HTTPS connections, which is commonly used for mobile SCADA access.

💡 Hint

Common Mistakes

Using 'none' disables authentication, which is insecure.

Using 'anonymous' or 'guest' allows access without credentials.

OAuth2 is a secure and widely used authentication method suitable for mobile SCADA access.

💡 Hint

Common Mistakes

Using a string instead of a number.

Using a negative number which is invalid.

Using None which is not a valid timeout value.

The timeout must be a positive integer representing seconds. 30 is valid, while strings, negative numbers, or None are invalid.

💡 Hint

Common Mistakes

Disabling SSL which makes communication insecure.

Using ERROR level which shows fewer logs.

SSL must be enabled (True) for secure communication. DEBUG logging level helps during development and troubleshooting.

5fill in blank

hard

Fill all three blanks to define a mobile SCADA user with role and access level.

SCADA systems

create_user(username='[1]', role='[2]', access_level=[3])

Drag options to blanks, or click blank then click option'

Aoperator

Badmin

C5

Dguest

💡 Hint

Common Mistakes

Using 'guest' role which has limited access.

Using access_level as a string instead of a number.

The username is 'operator', role is 'admin' for full control, and access_level 5 represents highest privileges.
