To mitigate Layer 4 DDoS attacks, the best approach is to roll out a Content Delivery Network (CDN). A CDN can distribute incoming traffic across multiple distributed servers, reducing the load on a single point and making it more difficult for an attacker to overwhelm the system. Many CDN providers also offer integrated DDoS protection services, which can absorb and filter malicious traffic. This makes a CDN the most effective control for handling volumetric attacks like those at Layer 4.
"Security Considerations for Content Delivery Networks" published by the Cloud Security Alliance (CSA) - CDN offer DDoS attack protection
Roll out a CDN (Content Delivery Network) is usually the most effective. CDNs can help distribute network traffic across a network of distributed servers. This can effectively mitigate DDoS attacks by dispersing the traffic geographically and making it more difficult for attackers to overwhelm a single point of the network. Additionally, many CDN providers offer DDoS protection as part of their services, with the ability to absorb large amounts of traffic and to identify and block malicious traffic patterns.
According Mike Chapple's CompTIA CySa+ guide its CDN (p.419)
On the study guide that is a page with questions on it. Page 419? Are you sure? Maybe it's the paper version because I have the ebook. There's no mention of Cdn in either the Comptia study guide or the certmaster practice.
A. Block the attacks using firewall rules
I agree with CDN. It can block or rate-limit traffic from known malicious IP addresses, preventing them from overwhelming the network. It filter traffic based on protocols and detect unusual patterns that indicate a DDoS attack, allowing for quick mitigation. Automated tools within the CDN infrastructure can detect and respond to DDoS attacks in real-time, reducing response time and minimizing the attack’s impact.
The answer is C: CDN. Akamai and Cloudflare offers DDoS protection by using CDN to offload the traffic on their infrastructure and routing it through a null interface. Using proxy and caches you can mitigate a DDoS
c reason ddos is a volumetric attack and to mitigate or reduce impacts on an organization, its best to go for CDN as firewall can not mitigate ddos
A. Block the attacks using firewall rules
For mitigating Layer 4 Distributed Denial of Service (DDoS) attacks, blocking the attacks using firewall rules is a common and effective measure. Firewalls can be configured to filter and block traffic based on various criteria, such as IP addresses, protocols, and ports. By setting up appropriate firewall rules, the security team can prevent malicious traffic associated with Layer 4 DDoS attacks from reaching the targeted website, thereby protecting the network infrastructure and ensuring the availability of the service.
