About DDoS Attacks:
- What is a DDoS Attack?
-
- A Distributed Denial of Service (DDoS) attack floods a server or network with excessive traffic, causing service disruptions.
- It leverages a botnet a network of compromised devices—to send overwhelming requests to the target system.
- How Does a DDoS Attack Work?
-
- Botnet Formation: Hackers infect multiple devices with malware, converting them into bots.
- Traffic Overload: The botnet directs massive fake requests to the target, exhausting bandwidth or processing power.
- Service Disruption: Legitimate users experience slowdowns or complete service failure.
- Diversion Tactic: Attackers may use DDoS as a smokescreen for data breaches or malware deployment.
- How to Counter a DDoS Attack?
-
- Traffic Filtering: Identify and block malicious requests using AI-based monitoring.
- Rate Limiting: Restrict the number of requests per user to prevent overload.
- Bot Detection Tools: Use CAPTCHA and behavioral analysis to block automated attacks.
- Robust Authentication: Strengthen login security to prevent unauthorized access.
- Incident Response Teams: Establish cybersecurity teams to monitor, detect, and mitigate threats.
