Why is securing MongoDB important?

Which of the following is the main reason why securing MongoDB databases is critical?

A To prevent unauthorized access that could lead to data theft or loss

B To improve the speed of database queries

C To reduce the size of the database files

D To allow anyone to read data without restrictions

💡 Hint

Think about what happens if someone who shouldn't access the data gets in.

Securing MongoDB is essential to protect sensitive data from unauthorized users who might steal, change, or delete it.

Effect of no authentication on MongoDB access

If a MongoDB instance has authentication disabled, what will be the result when a user tries to connect?

A The user can connect and access all data without providing credentials

B The user will be blocked and receive an authentication error

C The database will automatically encrypt all data

D The user can only read data but cannot write

💡 Hint

Think about what happens when no password or user check is required.

Without authentication, MongoDB allows anyone to connect and access data freely, which is a security risk.

Identify the correct command to enable authentication in MongoDB configuration

Which of the following configuration snippets correctly enables authentication in MongoDB's config file?

MongoDB

security:
  authorization: enabled

A

security:
  enableAuthorization: yes

B

security:
  authentication: true

C

security:
  auth: on

D

security:
  authorization: enabled

💡 Hint

Look for the exact keyword MongoDB uses for enabling authorization.

MongoDB uses 'authorization: enabled' under the 'security' section to turn on access control.

Best practice to secure MongoDB exposed to the internet

Which option is the best practice to secure a MongoDB server that must be accessible over the internet?

A Store all data in plain text for faster retrieval

B Disable authentication to allow easy access and speed up connections

C Enable authentication, use strong passwords, and restrict IP access with firewalls

D Allow all IP addresses to connect without restrictions

💡 Hint

Think about layers of protection beyond just passwords.

Combining authentication, strong passwords, and IP restrictions helps protect MongoDB from unauthorized internet access.

Why does this MongoDB connection fail with authentication enabled?

Given the MongoDB server has authentication enabled, why does this connection attempt fail? Code: ``` mongo --host localhost --port 27017 ``` Options:

A Because the port number 27017 is incorrect

B Because the connection command does not include username and password for authentication

C Because the host 'localhost' is misspelled

D Because the MongoDB server is not running

💡 Hint

Think about what authentication enabled means for connecting clients.

When authentication is enabled, clients must provide valid credentials to connect. Omitting them causes failure.
