When It Comes To DDoS Attacks, Little Ones Are The New Big Ones

  • The case for DDoS managed mitigation and protection services is well established. By partnering with a vendor who can monitor system operation, you can solve top IT issues, increase staff resources, and gain access to the DDoS experience. However, not all managed ddos services are similar. How can you distinguish the good from the simply good? Here are some features to look for.

    Cyber ​​criminals launch Distributed Denial of Service (DDoS) attacks for a variety of reasons. However, for competitive advantage, hacktivism and, increasingly, financial gain. Historically, attacks were primarily brute force and used a lot of traffic to block legitimate user access to a web server, service, or application. However, as reported by Corero's cloud partner Neustar, as the cybercrime community becomes more sophisticated, they become saturated, causing subtle declines in network services and overwhelming the stateful nature of devices. network. Includes firewalls and routers. In recent years, Corero's research on attacks on clients has shown that the overwhelming majority of attacks (98%) are not large in volume and are actually less than 10 Gbps. These below-saturation attacks don't make headlines, but make no mistake about it, they can do so much damage.

    Stealth Attacks Are More Effective

    Many organizations are unaware of the changing landscape of DDoS threats. In many ways, that is the purpose of modern cybercriminals. Create and use attack methods that go unnoticed by traditional protection solutions. Organizations need to be very concerned about stealthy DDoS attacks for several reasons.

    First, the technique used is not only difficult to detect using a manual or legacy approach, but with these older solutions it's almost impossible to mitigate all incoming traffic to the target without blocking it. And effectively complete the attack on the perpetrator.

    Second, a small attack can disrupt a corporate firewall in seconds, blocking legitimate traffic flow, or in some cases meddling in a network, mapping, malware, or stealing sensitive data. It can be possible. Obviously, this can be much more damaging than taking a website or service offline.

    Third, and most importantly, this stealthier DDoS traffic is very effective in impacting service and application performance. Poor service can affect an organization's ability to conduct business online effectively. This is generally unacceptable in a world connected to the Internet that expects a high degree of responsiveness. Delaying a system response for a few seconds or creating a small amount of downtime can be costly in terms of customer loyalty, loss of revenue, or poor brand reputation.

    These small attacks are of particular interest to Internet and hosting service providers. They're not saturated, so they don't steal a lot of bandwidth individually. The overall impact of increasing the frequency of such DDoS traffic passing through the network can be costly in terms of updating and maintaining the network infrastructure. Also, as previously reported, his reputation is at stake here. Many organizations have the impression that their providers are already protecting against such attacks.

     How to defend against both stealth attacks and massive DDoS attacks

    Small DDoS attacks are deliberately covered up, so they are unlikely to reach the thresholds necessary to evade detection of homegrown DDoS protection tools or trigger cloud-based debugging solutions on demand. Become. Additionally, for cloud-based debugging solutions, it takes a few minutes (usually more than 10) to divert traffic to the service and activate the required mitigations. By then, the attack has already done damage. If an organization does not have a real-time granular view of DDoS traffic, it can lead to a service impact or outages that may not be resolved as another IT problem.

    Organizations working to maximize the continuity of their online business must be protected from all kinds of DDoS, not just from major brute force attacks. Fortunately, the latest generation of DDoS solutions can block large numbers of stealth and sub-saturation attacks and block them in seconds. And, in rare cases where there is a risk of increased attack and link saturation, the fully integrated hybrid DDoS protection solution provides an optimal combination of fast, accurate, on-premises protection with a coordinated automated cloud. It can be provided. Backup to ensure that even the largest attacks will not succeed.
