Question: Which Three Protocols Can Use Advanced Encryption Standard AES )?

Which three protocols can use advanced encryption standard?

AES includes three block ciphers: AES-128, AES-192 and AES-256.

AES-128 uses a 128-bit key length to encrypt and decrypt a block of messages, while AES-192 uses a 192-bit key length and AES-256 a 256-bit key length to encrypt and decrypt messages..

What approach to availability provides the most comprehensive?

What approach to availability provides the most comprehensive protection because multiple defenses coordinate together to prevent attacks? Explanation: Defense in depth utilizes multiple layers of security controls.

What are two methods that ensure confidentiality?

What are two methods that ensure confidentiality? (Choose two.)authorization.availability.nonrepudiation.authentication.integrity.encryption. Explanation: Confidentiality means viewing of information only for those who need to know. This can be accomplished by encrypting data and authenticating users who request access.

SHA-1 and SHA-2 are the hash algorithms required by law for use in certain U.S. government applications, including use within other cryptographic algorithms and protocols, for the protection of sensitive unclassified information.

What is an example of data in motion?

Data being sent over an email or through workstream collaboration platforms like Slack, being transferred to a USB device or to a cloud storage are examples of data in motion. When it arrives, it becomes data at rest. Data in motion is also known as data in transit or data in flight.

What are three states of data during which data is vulnerable?

There are three basic states of data: data at rest, data in motion, and data in use. Below you will find brief descriptions of the three states of data as well as the kinds of encryption and security needed to protect it. Data at rest is a term that refers to data stored on a device or backup medium in any form.

Which algorithm will windows use by default?

By default, the Windows Vista and the Windows Server 2003 implementation of EFS uses the Advanced Encryption Standard (AES) with a 256-bit key.

What are the two most effective ways to defend against malware?

Which two reasons describe why WEP is a weak protocol choose two group of answer choices?

Which two reasons describe why WEP is a weak protocol? (Choose two.)WEP uses the same encryption features as Bluetooth.Everyone on the network uses a different key.The key is static and repeats on a congested network.The default settings cannot be modified.The key is transmitted in clear text. Explanation:

What is the most difficult part of designing a cryptosystem?

key managementAnswer: The most difficult part of designing a crypto system is key management.

How do you protect data at rest?

Encryption at rest is designed to prevent the outsiders from accessing the unencrypted data by ensuring the sensitive data is encrypted when on disk. If an attacker obtains a hard drive with encrypted data but not the encryption keys, the attacker must defeat the encryption to read the data.
