Partial-Link Saturation Leads to Performance Degradation

Sub-saturating DDoS attacks cause network congestion and service degradation. This is especially important in a Carrier (Internet Service Provider or Hosting Provider) environment because 1) even small attacks can saturate a customer downstream, and we all know that in an always-on world, network reliability is crucial for subscribers, 2) DDoS traffic is costly to transit across the network, and 3) downtime impacts Service Level Agreements (SLAs). In the highly competitive Carrier arena, SLAs often promise optimum network reliability; the only way to guarantee that is by using an always-on, in-line DDoS mitigation appliance.

Solutions for Effective DDoS Mitigation

The fact is that legacy DDoS mitigation solutions, such as scrubbing, completely overlook the small, low-threshold attacks. Just because a DDoS attack is small doesn’t mean it isn’t a huge problem. It takes hackers only a few minutes to map a network, steal date, install malware, or discover your network vulnerabilities; by the time security staff notice a low-threshold attack in progress and divert traffic to be cleaned at an out-of-band scrubbing center, the damage has likely already been done.

What is a DDoS Attack? A Simple Definition

Since we’re all about making technical topics simple, let’s start with a basic answer to the question: What does DDoS mean (a.k.a. “What is a distributed denial of service attack”)? As mentioned above, a DDoS attack is a bit like a traffic jam on a website (but it’s intentionally caused by a hacker). Here’s a simple definition for the meaning of DDoS: A DDoS (distributed-denial-of-service) attack is when a hacker makes a website or other service inaccessible by flooding it with requests from many different devices. If you’ve also heard the term “DoS attack,” don’t let that confuse you. A DDoS attack is just a specific type of DoS (denial-of-service) attack — one that uses multiple computers/devices to attack with. How Does a DDoS Attack Work ? Just like a traffic jam floods a highway with more cars than it can handle, a DDoS attack floods a website with more requests (i.e. visitors) than the web server or other related systems can handle. Many hackers use botnets (a.k.a.

How to prevent a DDoS?

Keeping yourself protected from DDoS attacks is something that is often easier said than done because of the fact cybercriminals will often stop at nothing to gain unauthorised access to private data, and many international brands such as Netflix, AirBnB, and Spotify have all become victims in the past. In spite of this, there are certain things that can be done in an effort to prevent a DDoS attack from occurring. Denial of service attack definition Firstly, you will need to make sure that any firewalls and routers are configured in the correct manner and applied with up-to-date security patches. Similarly, it’s also worth regularly checking for security updates for your Internet of Things (IoT) devices and adding a password where possible. This is because these devices have been increasingly targeted by hackers in recent years. Doing everything in your power to keep things up to date will ensure that any bogus traffic is promptly rejected during a process whereby network traff
