How to stop DDoS attacks with a small budget?
On October 21, 2016, the most significant DDoS assault (DNS related) in history happened, cutting down huge organizations like PayPal, Spotify, Twitter, Reddit, and eBay. Some even considered it the DNS Doomsday of the web. As the web keeps developing, it's not astounding that DDoS assaults are on the ascent at an alarming rate. Indeed, as per information gave from easy DNS, DDoS assaults after some time is deteriorating. For a ton of destinations, it may very well involve time until you are hit.
Why DDoS attacks are dangerous for business
DDoS attacks work by spamming a worker with gigantic quantities of requests that over-burden its ability to meet them. The aftereffect of this is that real traffic can't associate, and the worker is disconnected. It's a genuinely direct strategy for assault and one that should be possible without incredible specialized information - you can even purchase DDoS as an assistance pack on the dark web that will accomplish the work for you. Be that as it may, the effect can be decimating.
Previously, DDoS assaults may have been viewed as, to a greater degree, an irritation than a genuine danger to organizations, yet this is not true anymore. This is an enormous part of the colossal multiplication of effectively hackable Internet of Things gadgets that make it simple to create a vast botnet to flood focused on locales with traffic. Subsequently, assaults can be more extraordinary and last more than any time in recent memory, which means even the most prominent organizations are in danger.
In any case, they keep up their overall effortlessness and can be hard to stop, which implies organizations should have explicit DDoS safeguards in their security technique.
Means of protection against DDoS for a small budget
The best means of how to stop DDoS attacks for a small budget is the DIY method. However, DIY security is broadly viewed as a frail way to deal with DDoS moderation. In reasonable terms, it depends on setting static traffic limits (e.g., utilizing mod_evasive) and unpredictable IP boycotting rules. It is, for the most part, liked for budgetary reasons yet hardly considered by online organizations.
If you are searching for affordable means of how to stop DDoS attacks, keep reading to find the cheapest and most reliable means in your budget. By combining a few tricks to reduce the attack surface, you can certainly survive a DDoS attack with a small budget, and we will explain how to do that in a few paragraphs.
- Ensure to make your server as fast as possible
For a start, your web server should be as fast as possible. In other words, it must be able to answer a request in milliseconds. If you are using an IIS server, the easiest way to achieve this is to enable HTTP Keep-Alive. This will allow your webserver to process multiple requests in parallel using a single connection.
- Make use of a CDN service
Another way to achieve a high rate of requests per second is to use a CDN service. This is a distributed network of servers that will send your content to the end-user instead of your web server. This way, your web server only needs to deal with requests from the CDN servers.
A CDN service can undoubtedly help you mitigate a DDoS attack with a small budget, but you will still need to implement a few other things to increase your protection level.
Note! Never expose a single IP address to the Internet. There are several ways to achieve this, but the easiest one is to use a reverse proxy.
A reverse proxy server can accept incoming requests and forward them to your web server. The web server will then decide if the reverse proxy server can handle the request or if it needs to be sent to a different server. This way, you can have multiple web servers behind a single IP address or have a single server with multiple IP addresses (VIPs).
- The use of SSL encryption
Another trick to reduce your attack surface is to use SSL encryption. With SSL, you can secure your web server, the reverse proxy server, and your CDN servers. This way, your attackers are unable to access your network because all your servers use encryption.
Other Ways to Protect
- On-premise appliances
The on-premise way to deal with DDoS security utilizes hardware appliances conveyed inside an organization before ensuring workers.
As a rule, these kinds of appliances have progressed traffic sifting abilities outfitted with a blend of geo-blocking, rate restriction, IP notoriety, and mark identification of signature.
You can viably use regular mitigation appliances to sift through harmful approaching traffic. This makes them a feasible choice for halting application layer assaults.
- Off-premise cloud-based solutions
Generally, off-premise solutions are either ISP-gave or cloud-based. While ISPs commonly offer just organization layer assurance, cloud-based solutions give extra separating abilities to stop application layer assaults. Both offer practically boundless adaptability, as they are sent outside of an organization and aren't obliged by the already distinguished uplink limits.
That's it! Using this simple advice, you will block all known techniques for DDOS attacks, and it will force your attackers to use more advanced techniques.
