Simulation

Simulation

A computational process designed to predict the behavior of a real-world or physical system.

What is the purpose of simulation?

To study a system’s behavior prior to building it by performing 'What if' scenarios.

Discrete Time Simulation

Models continuous systems that change over time at discrete intervals driven by clock ticks.

Discrete Event Simulation

Models a system over time where events drive the simulation forward.

Monte Carlo Simulation

A mathematical technique that predicts possible outcomes of uncertain events using repeated random sampling.

Financial Simulation

Focuses on budgeting, forecasting, and investment decisions within a business.

Encryption

The process of encoding information by converting plaintext into ciphertext.

Authentication

The act of proving the identity of a computer system user.

Symmetric Encryption

Uses a single secret password or key for both encrypting and decrypting data.

Asymmetric Encryption

Uses two keys, a public key for encryption and a private key for decryption.

Advanced Encryption Standard (AES)

A form of symmetric encryption.

Rivest-Shamir-Adleman (RSA)

A form of asymmetric encryption.

Hash Algorithm

A mathematical function that converts input values into compressed numerical values.

Base64 Encoding

A binary-to-text encoding method that translates 8-bit bytes into 6-bit groups.

Digital Certificate

A trusted document containing a public key, identity of the owner, and a digital signature.

Certificate Authority (CA)

An entity that issues digital certificates.

Transport Layer Security (TLS)

Protects data sent between systems using a combination of symmetric and asymmetric cryptography.

What are password attacks?

Attacks such as brute force and dictionary attacks designed to guess passwords.

Multifactor Authentication

A security approach requiring a combination of two or more credentials for user verification.

What is a brute force attack?

A method that uses software to generate every possible combination of characters to crack a password.

What is a dictionary attack?

A method that helps hackers guess a password by systematically going through a list of words.
