Learners will be introduced to a series of different authentication solutions and protocols, including RSA SecureID and Kerberos, in the context of a canonical schema. The basics of cryptography are also introduced with attention to conventional block ciphers as well as public key cryptography.
An attacker is trying to compromise a wireless network that has been secured using WPÁ-PSK and AES. She first tried using AirSnort to capture packets, but found that she couldn't break the encryption. As an alternative, she used software to configure her laptop to function as an access point.

From there, Ethernet and wireless connections are used to create a small network within your home. Which of the following protocols would be used to provide authentication, authorization, and accounting for the Internet connection? You often travel away from the office.
As a security precaution, you have implemented IPsec that is used between any two devices on your network. IPsec provides encryption for traffic between devices. You would like to implement a solution that can scan the contents of the encrypted traffic to prevent any malicious attacks.
RSA encryption, in full Rivest-Shamir-Adleman encryption, type of public-key cryptography widely used for data encryption of e-mail and other digital transactions over the Internet.
RSA is secure, but it's being implemented insecurely in many cases by IoT manufacturers. More than 1 in every 172 RSA keys are at risk of compromise due to factoring attacks. ECC is a more secure alternative to RSA because: ECC keys are smaller yet more secure than RSA because they don't rely on RNGs.
Introduced in 1977 by MIT colleagues Ron Rivest, Adi Shamir, and Leonard Adleman, RSA—its name derived from the initials of their surnames—is a specific type of public-key cryptography, or PKC, innovated in 1976 by Whitfield Diffie, Martin Hellman, and Ralph Merkle.
RSA key is a private key based on RSA algorithm. Private Key is used for authentication and a symmetric key exchange during establishment of an SSL/TLS session. It is a part of the public key infrastructure that is generally used in case of SSL certificates.
RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of the keys can be given to anyone.
The RSA token authentication mechanism has its own root certificate which signs personal certificates that are used to encrypt and sign parts of the token. The data stored in an RSA token is based on the identity of the client subject.
RSA is neither better nor worse than AES, as the two are designed for completely different use cases. RSA is an asymmetric algorithm designed for public-key cryptography. AES is a symmetric algorithm designed for private-key cryptography. It's faster than RSA but only works when both parties share a private key.
Currently the standard is 2,048-bit RSA keys, up from 1,024, which was allowable until just a few years ago. Some organizations use 3,072-bit and 4,096-bit keys, but as RSA key sizes grow, the amount of security provided by them isn't commensurate to the amount of computational power that will be required to use them.
This course introduces the basics of cyber defense starting with foundational models such as Bell-LaPadula and information flow frameworks. These underlying policy enforcements mechanisms help introduce basic functional protections, starting with authentication methods.
This module introduces important protocols and techniques associated with advanced authentication processes.
