Over the past few years, DDoS attacks have risen sharply, targeting many large companies, including high-profile companies such as Google, Visa, Paypal, Sony, Deezer, and Evernote.
Many experts say traditional methods for preventing and mitigating them are becoming less and less useful, but can help SAVI to do so? Here we have written what are DDoS attacks and what can we do to prevent them.
What are DDoS attacks?
A Distributed Denial of Service (DDoS) is essentially an attempt to make a website or online service unavailable to users. There are a number of different methods for performing a DDoS attack, but one of the most common is sending large requests in order to overload the server, making it unable to answer legitimate requests. Anyone who wants to visit that site or service will either have no access or will be provided with limited experience, which can undoubtedly have a great impact on 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 disappointed service, and bringing huge revenue loss to Sony.
It is worth noting that it is not just the immediate impact that can cause damage to the company, it can have continuous reputation damage if the company is perceived by others as unable to provide a durable and reliable experience in users. No one wants the availability of the service to be fluctuating.
How to protect your company?
Source Address Validation Improvement (SAVI) is one of the ways to protect your company from such threats. DDoS attacks are a typical way to use the fact that an IP does not possess a powerful authentication mechanism, which shows that the packet comes from where it claims it comes. So, the packet simply claims to have originated from a given address, and does not indicate any way that the host sending the package is safe.
SAVI methods have been developed by the Internet Engineering Task Force (IETF) to prevent such scams. SAVI works to mitigate the risk of attached nodes in the same IP links from scams that can cause IP addresses to each other, by completely performing IP filtering to provide an accurate source.
In summary, all businesses of any size should be aware of how to protect themselves against DDoS attacks and what can cause them to their reputation. If people are more aware of security issues and their avoidance, the internet and websites will continue to be an extraordinary resource for everyone.
