Introduction to DDoS attacks
On September 8, 2019, online players of the epic World of Warcraft game from Blizzard, were very mad. They were having many problems with the sport, some were dropping off, some unable to log into, and a few even incurred penalties if disconnected from competitive modes. After three hours of latency, quite a 1000 tweets from angry fans rained on Blizzard, dissatisfied players vented out their frustrations online. While the IT team at Blizzard kept updating its fans, it had been still 48 hours before they might bring back the location to normal status.
Just two days before this attack, Wikipedia suffered what appears to be the foremost disruptive Distributed Denial of Service (DDoS) attack in recent memory. Historically, Wikipedia had been attacked a few times, but this point it had been different. The attack was far larger and went on for nearly 3 days. the location became unavailable in Europe, Africa, and therefore the Middle East, and bogged down for users within the US and Asia.
Attacks just like the ones mentioned above aren’t rare. In fact, last year, over 8.4 million attacks occurred. That amounts to 23000 attacks a day, i.e. 16 every minute. the typical cost of an attack starts from $50,000/- moving upwards. to not mention the loss of productivity, customer trust, and competitive disadvantage. during a recent survey, 78% of security professionals said that the foremost damaging effect of DDoS attacks on businesses was customer confidence and trust.
Why attacks are increasing
The number of DDoS attacks has grown significantly across industry segments and business sizes. There were a 168% increase in distributed denial-of-service (DDoS) attacks in Q4′ 19, compared with Q4’18, and a 180% increase overall in 2019 compared to 2018. the rationale for this alarming rise in attacks might be the straightforward availability of DDoS-for-hire within the dark web, making it such a lot easier and price effective for perpetrators to cause damage to enterprises by launching malicious attacks. There are other reasons too. Some attacks are launched by `activists’, targeting ideologically different businesses. Also, business feuds are fairly often cited as a reason for launching DDoS attacks. There are people that are so bored that launching an attack gives them an adrenaline rush. But the only motive is money, as attacks are launched to extort money.
How Confident are you about your DDoS attacks Mitigation efficiency?
To prevent attacks, enterprises, both small and enormous have likely invested in one or the opposite mitigation solutions highlighted below:
- Scrubbing Center (BGP)
- Content Delivery Network (CDN)
- Vendor Appliances (CPE Equipment)
- Intrusion Detection System/Intrusion Prevention System
- Web Application Firewall
There are generally three sorts of DDoS mitigation postures:
- Cloud based,
- On-Prem solutions,
- Hybrid combinations of the 2.
