Wire encryption for data in transit in Hadoop - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable wire encryption in Hadoop configuration.

Hadoop

conf.set("[1]", "true")

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

Adfs.encrypt.data.transfer

Bdfs.data.transfer.protection

Cdfs.encrypt.wire

💡 Hint

Common Mistakes

Using a property that controls data protection but not encryption.

Confusing encryption with general data security settings.

The property dfs.encrypt.data.transfer enables wire encryption for data in transit in Hadoop.

2fill in blank

medium

Complete the code to set the encryption cipher suite for Hadoop wire encryption.

Hadoop

conf.set("dfs.encrypt.data.transfer.cipher.suites", "[1]")

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

ARSA/ECB/PKCS1Padding

BAES/CTR/NoPadding

CDES/CBC/PKCS5Padding

DBlowfish/CFB/NoPadding

💡 Hint

Common Mistakes

Choosing RSA which is asymmetric and not used for bulk data encryption.

Selecting DES which is outdated and insecure.

The recommended cipher suite for Hadoop wire encryption is AES/CTR/NoPadding for performance and security.

3fill in blank

hard

Fix the error in the code to correctly enable data transfer encryption in Hadoop.

Hadoop

conf.setBoolean("[1]", true)

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

Adfs.encrypt.data.transfer

Bdfs.data.transfer.protection

Cdfs.encrypt.wire

Ddfs.data.encryption.enabled

Attempts:

3 left

💡 Hint

Common Mistakes

Using a property that controls data protection but not encryption.

Using a property that does not exist in Hadoop configuration.

The correct property to enable encryption is dfs.encrypt.data.transfer. Using other properties will not enable wire encryption.

4fill in blank

hard

Fill both blanks to create a dictionary of encryption settings for Hadoop wire encryption.

Hadoop

encryption_settings = {"[1]": "true", "[2]": "AES/CTR/NoPadding"}

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

Adfs.encrypt.data.transfer

Bdfs.data.transfer.protection

Cdfs.encrypt.data.transfer.cipher.suites

Ddfs.data.encryption.enabled

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up the keys for enabling encryption and setting cipher suite.

Using keys that do not exist in Hadoop configuration.

The dictionary keys must be dfs.encrypt.data.transfer to enable encryption and dfs.encrypt.data.transfer.cipher.suites to specify the cipher.

5fill in blank

hard

Fill all three blanks to create a Hadoop configuration snippet that enables wire encryption, sets the cipher, and enables data transfer protection.

Hadoop

conf.setBoolean("[1]", true)
conf.set("[2]", "AES/CTR/NoPadding")
conf.set("[3]", "privacy")

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

Adfs.encrypt.data.transfer

Bdfs.encrypt.data.transfer.cipher.suites

Cdfs.data.transfer.protection

Ddfs.data.encryption.enabled

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing the properties for encryption and protection.

Using incorrect property names or wrong data types.

This snippet enables wire encryption (dfs.encrypt.data.transfer), sets the cipher suite (dfs.encrypt.data.transfer.cipher.suites), and enables data transfer protection (dfs.data.transfer.protection).
