# Cyber Threats and Countermeasures

## Module Overview

This module focuses on various types of attacks to networks and computer systems and tools to defend against them. It is divided into two main parts:

Part 1. Threats: where you learn about phases of an attack and common types of attacks

Part 2. Countermeasures: Where you learn about countermeasures against threats. This part is divided into two subparts: 1) Networks defenses and 2) OS and application security

## Module Objectives

By the end of this module you should be able to:

- Explain the five phases of an attack to a computer system or network,
- Name and describe tools that could be used at each phase in an attack,
