Launch you career in cyber security.
This specialization in intended for IT professionals, computer programmers, managers, IT security professionals who like to move up ladder, who are seeking to develop network system security skills. Through four courses, we will cover the Design and Analyze Secure Networked Systems, Develop Secure Programs with Basic Cryptography and Crypto API, Hacking and Patching Web Applications, Perform Penetration Testing, and Secure Networked Systems with Firewall and IDS, which will prepare you to perform tasks as Cyber Security Engineer, IT Security Analyst, and Cyber Security Analyst.
Course 1 - Design and Analyze Secure Networked Systems
University of Colorado System
About this Course
In this MOOC, we will learn the basic cyber security concepts, how to identify vulnerabilities/threat in a network system. We will apply CIA basic security services in the triage of recent cyberattack incidents, such as OPM data breach. We will learn the risk management framework for analyzing the risks in a network system, and apply the basic security design principles to protect the data and secure computer systems. We will examine the trustworthiness of programs and data installed in our systems and show the proper way to verify their integrity and authenticity. We will apply principle of least privileges for controlling the shared access given to different groups of users and system processes. On Amazon Cloud instances, we will use GnuPG software to generate public/private key pair for signing/verifying documents and open source software, and for encrypting documents. We will learn how to publish software, the related signature and release key on web server and publish public key to PGP key server for others to retrieve. We will learn Public Key Infrastructure (PKI) and Linux utility to serve as a CA for an organization, learn how to sign certificate request for clients or servers in secure email and web applications.
Module 4 - Be a CA, Setup Secure Server and Client Certificate
In this module, we will learn the Public Key Infrastructure (PKI), how CA operates, and the certificates signing and verification process. We will utilize the utility command in a Linux system to serve as a CA for an organization, learn how to sign certificate request for clients or servers both secure email or secure web access purpose. We will earn how to generate server certificate requests as a webmaster, send them to CA for signing and install the signed certificates in Apache web server for secure web access. We will also set up apache web server for requiring clients to present their client certificates for mutual authentication. We will also guide you to set client certificate on browser for mutual authentication and on a mail client for signing and encrypting emails.
