What are DDoS attacks ?

During recent years, DDoS attacks increased significantly since many target large companies, including those of high-profile Google, Visa, Paypal, Sony, Deezer, and Evernote.

Many experts say that traditional methods for their prevention and mitigation are becoming less useful, but can help SAVI for this? Here we write what are DDoS attacks and what can we do to prevent them.

What are DDoS attacks?

A DDoS attack (Distributed Denial of Service) is basically an attempt to make a website or online service unavailable to users. Is a large number of different methods for conducting a DDoS attack, but one of the most common is to send high level of demand in order to overload the server, thus making it unable to respond to legitimate requests. Anyone who wants to visit the website or service or not will have no access, or will be offered a limited experience, which obviously can affect many businesses.

Organizations of any size have been targeted, including Sony Playstation company, whose network is often affected by DDoS attacks leaving players who paid him disillusioned service, and bringing huge losses of revenue to Sony.

It's worth noting that it is not only the immediate impact that can cause damage to the company, there may be ongoing damage to reputation if the company achieved perceived by others as unable to provide a consistent experience and reliable to users. Nobody wants that service availability is volatile.

How to protect your company?

Source Address Validation Improvement (SAVI) is one way to protect your company from such threats. DDoS attacks are a typical way to use the fact that an IP does not have a powerful mechanism for authentication, which indicates that the packet comes from a country where it claims to come. So simple package claims to have originated from a certain address, and does not show any way to the host that sends the packet is safe.

SAVI's methods have been developed by the Internet Engineering Task Force (IETF) to prevent such fraud. SAVI working to mitigate the risk of nodes attached to IP connections same scams that can cause to one another IP address, fully performing IP filtering to provide a source of estimable.

In summary, all businesses of any size should be aware of how to protect themselves from DDoS attacks and what can cause them to their reputation. If people are more aware of security issues and avoiding them, the Internet and websites will continue to be a tremendous resource for all.
