Denial of Service Attacks and Protection

A Distributed Denial of Service (DDoS) attack is a type of cyberattack in which multiple systems flood the bandwidth or resources of a targeted server, service, or network, causing it to become unavailable to legitimate users. The attack overwhelms the target with a flood of traffic, making it unable to respond to normal requests. The "distributed" nature of these attacks means that the traffic originates from many different sources, often using a botnet—a network of compromised computers or devices.

Business Impact of a DDoS Attack

1. Downtime: A successful DDoS attack can cause significant downtime, preventing employees, customers, and partners from accessing critical services or websites.
2. Revenue Loss: For businesses reliant on online services (e.g., e-commerce, banking), downtime directly translates to loss of revenue as customers are unable to complete transactions.
3. Reputational Damage: Prolonged or frequent attacks can erode trust in a company's ability to provide reliable services, leading to lost customers and business opportunities.
4. Increased Costs: Businesses may face increased operational costs to mitigate the attack, recover lost services, and handle customer complaints. Long-term, these attacks can also lead to higher costs for cybersecurity insurance.
5. Regulatory and Legal Issues: In industries like finance and healthcare, where uptime is crucial, a DDoS attack may trigger compliance violations and legal consequences.
