Follow along with the in-class demonstration to learn how the Caesar Cipher (also known as the Shift Cipher) works, and how you can use it to encode and decode text messages.
Follow the Instructable to learn how keywords can be incorporated with this cipher to make it more difficult to decrypt.
I have placed 8 encrypted messages around the perimeter of the room. Work together to decrypt them all! Submit a Google Doc to my Google Classroom page with the decrypted messages by the end of the day tomorrow.
Some of the decrypted messages lead to treasure! The first to decode each message gets the goods!
Remember, you may work together, but each student must submit their own original document to the Google Classroom page by tomorrow to receive credit for the lab. Don’t put more than one name on your document, and don’t submit someone else’s document as your own!

the most common authentication types and when to use them.
Explain
the purpose of multifactor authentication.
Describe
various models for creating and maintaining access control lists.
Explain
why access control frameworks need to keep track of who gains access to the system.
Type 1 Authentication A type of authentication that requires the user to provide something that they know, such as a password or PIN.
Type 2 Authentication A type of authentication that requires the user to provide something that they have, such as a key, fob, electronic chip, or smart card.
Type 3 Authentication A type of authentication that requires the user to provide something that they are, such as a fingerprint, handprint, retinal pattern, face, or voice.
Multifactor Authentication Authentication that requires two or more evidences of authentication, usually of different types.
Single Sign-on A method of authenticating with one system to gain access to other related systems.
Discretionary Access Control (DAC) A type of access control where a user has complete control over a resource, and also determines the permissions other users have to those resources.
Role-based Access Control (RBAC) A type of access control that restricts access based on the user’s role in an organization.
Mandatory Access Control (MAC) A type of access control that historically was associated with multilevel security and military systems and may use a security clearance to restrict access to resources. The security manager controls the security policy, and users aren’t able to override the policy.
Accounting The process of keeping track of user activity while attached to a system.
Logging The capturing and storing of computer and user events.
