As security professionals, we are expected to write code. In this practical activity, you will develop a Chrome browser extension that detects mailicious websites based on their URLs, using Python.

Steganography is the practice of hiding a message, image, or file within another message, image, or file. It can be used to send secret messages or to protect the confidentiality of data. In this tutorial, you will learn how to perform steganography.

A mathematical procedure called an encryption algorithm is used to turn plaintext (material that has not been encrypted) into ciphertext (encrypted data). There are many encryption algorithms out there, each with its own advantages and disadvantages. The method we choose is based on the security requirements of the system in use. In this tutorial, you will learn how to create a simple encryption function in Python using the Caesar cipher method.

In this practical activity, you will install and use an open source IDS called Snort. Snort is an open-source Intrusion Detection System (IDS) that is used to monitor networks for suspicious activity. It is designed to detect and alert users to potential security threats, such as malware, network attacks, and other forms of malicious activity.
