DoS Attacks and Defense

Denial of Service (DoS) attacks are increasing in regularity and sophistication. These attacks can have massive negative impacts to an organization. As this threat vector continues to grow, it is important to understand how they work, and the tools and processes needed to keep your organization safe. DoS attacks can result in loss of revenue, brand damage, and a loss of customer trust. Security practitioners need to be able to build effective defense solutions. This hands-on lab is designed to help you better understand how these attacks work, how they are deployed and the mechanisms you can implement to protect your organization.
