For companies, it is more important than ever to have a deep understanding of how DDoS attacks work and how to improve their ability to defend against DDoS . Only by continuously strengthening the protection and improving the security performance of the server can we avoid being attacked, which will lead to losses.
For every enterprise, it is very important to have certain protective measures to resist large-scale DDoS attacks. Many classic forms of anti-DDoS measures are unable to make subtle distinctions between data shocks. Instead of separating legitimate data from malicious data, they simply discarded all incoming data indiscriminately.
And not every type of DDoS protection is effective against every attack. Traffic-based monitoring is effective for batch attacks, but not effective for network protocol and application attacks. On the other hand, packet analysis is valid for all three.
Current anti-DDoS measures should include four key requirements:
1. Precision
For companies, the implementation of a precise DDoS defense system is crucial. Unlike more blunt defense systems, such as remote trigger black hole filtering or RTBH, precise protection solutions can identify threats and mitigate them accordingly. This helps to avoid costly errors (such as false positives or negatives) that may deter legitimate users or cause false negatives.
2. Scalability
The largest DDoS attack reached 1.35 megabits per second in March 2018. Given the sheer scale of today's DDoS attacks, it is more important than ever to expand the depth, breadth and height of DDoS protection systems. Depending on the packet rate, the number of attacking bots and the bit rate of the attack, a system that cannot be scaled may prove to be insufficient.
3. Response efficiency in wartime
An automated anti-DDoS system can eliminate the need for expensive and time-consuming manual intervention. It should automatically detect, mitigate, report DDoS attacks and learn from them. This is especially true in the case of multi-vector attacks (using multiple techniques and methods at the same time).
4. Affordability
Companies can use smaller, more efficient, and more affordable DDoS protection systems to keep costs down without sacrificing performance. This reduces the amount of equipment required, reduces costs and reduces rack space, thereby saving time and money.
Unfortunately, because traffic inspection cannot detect complex network and application attacks; racks are required to create profitable clean plumbing services; well-trained experts are required to initiate time-consuming manual intervention; old systems are too expensive to be Expansion, the traditional system cannot fully meet the above four requirements.
Modern hackers are accustomed to using multiple types of attacks on a single target. Therefore, anti-DDoS solutions need to have four key requirements: accuracy, scalability, wartime response efficiency, and affordability. This is more important than ever. If it is not comprehensive, effective DDoS protection strategies will be insufficient. Companies should prioritize multi-layer hybrid solutions that can provide continuous protection from any type of DDoS attack.
