Career Pathway Course Units

Unit 1: Computer & Digital Forensics

Computer and digital forensics is an exciting and emerging field in forensic science. As the world becomes more digitally dependent, it’s only natural there would be an increase in computer-based crimes and a corresponding need to solve them because individuals and organizations alike are negatively impacted by computer crimes. As a result, law enforcement has become modernized by adding digital forensic experts or partnering with them to aid in the collection of evidence in hopes of identifying those responsible for computer crimes.

Unit 2: Cryptology & Cryptography

This unit will dive into the complexities of how data and communications are encrypted. There is a long history of employing creative methodologies to keep communications safe. From 400 BCE until today, significant advances have been made in breaking codes to gain access to information. So, while this is a complicated topic, it is critically important to the profession and the overall strategy for network security.

Unit 3: Operating System Administration

Every device that is connected to a network or the internet runs an operating system (OS). The OS provides the interface between the human operator and the computing hardware. Operating system administration requires talented individuals who understand OS software, hardware, the network, and human operators in order to make the overall network function smoothly. Each OS has its own personality, requirements, benefits, and frustrations. In this unit, we will explore the role of systems administrators and their challenges as well as the best practices that should be followed while managing different operating systems and devices.

Unit 4: Managing Users & Permissions

In this unit, we will examine how to deploy the first line of defense for our users and systems: passwords. They sound simple, but there is more to them than meets the eye, and vulnerabilities lurk everywhere. We will also examine and develop a process to manage a network’s users and discuss how to grant the permissions they need in order to complete their jobs. Through a process of continuous monitoring, the sysadmin team will be on the lookout for anomalies in the network to detect any compromises of user accounts that could lead to a larger data breach. We will cover all aspects of managing users to keep our systems secure.

Unit 5: Application Security

The application layer (layer 7) of the OSI is where users spend much of their time completing daily tasks and using different application (software) packages. Those tasks could include anything from running monthly payroll to ordering lunch online. Because of this, each application in your environment needs to be understood and evaluated for possible vulnerabilities. In this unit, we will take a deep dive into how to accomplish that analysis. And, of course, when talking about application security, we cannot ignore the users. It sounds accusatory, but they are the weakest link in our security framework. Users like to click on things before thinking, so do not forget to provide frequent security awareness training to your users!

Unit 6: Mobile Threats & Security

Mobile devices play vital roles in our everyday lives and allow us to access the internet. Some of us would become very anxious if we had to give up our smart devices even for a few hours. We use them to shop, work, entertain ourselves, communicate, and create. Because of this and the other ways we interact with our devices, they contain tremendous amounts of information about us and our lives. Being treasure troves of personal information, mobile devices have naturally become prime targets for hackers. In this unit, we will examine some common mobile device threats and vulnerabilities as well as mitigation strategies we can employ to keep our data safe. After completing this unit, you will be able to secure your mobile device against common threats.
