- Distributed Denial of Service, or DDoS for short, refers to a cyber attack resulting in victims being unable to access systems and network resources, essentially disrupting internet services.
- DDoS attacks are one of the most common forms of cyber attack, with the number of global DDoS attacks increasing to 50 million annually.
- The DDoS attack will attempt to make an online service or website unavailable by flooding it with unwanted traffic from multiple computers.
- For a DDoS attack to be successful, an attacker will spread malicious software to vulnerable computers, mainly through infected emails and attachments.
- This will create a network of infected machines which is called a botnet.
- The attacker can then instruct and control the botnet, commanding it to flood a certain site with traffic: so much that its network ceases to work, taking the site offline.
Why hackers choose DDoS attacks?
- DDoS attacks can take down websites of all sizes, from heavy-duty enterprises to smaller, more vulnerable sites.
- The moves for attacks can vary widely from politics to pure financial gain.
- DDoS attacks can be sold. So a buyer could request a certain site to be taken offline, and pay a sum for its execution.
- Revenge is often a motive in these cases.
- During a DDoS attack, an abnormally high amount of requests are sent to the host’s system, causing it to break down as the system is unable to process this amount of traffic.
- The processing of normal requests is, in turn, slowed down or even blocked completely.
- The DDoS attack comes from hacked computers across the globe, it’s also difficult to pinpoint from where and when it’s happening.
- .Web Application Firewall protects the Network (Layer 3), Transport (Layer 4), and Application (Layer 7) layers from DDoS Attacks.
- DDoS protection is an automated service that intelligently blacklists IP address that it recognizes as a malicious attack.
