We often find ourselves asking this very question: how long can a website survive once it experiences a DDoS attack? Today, a DDoS attack has entered the 1 Tbps DDoS attack era. February 27th, 2018, Radware experiences a sudden surge in activity on UDP port 11211.
Before the Radware’s ERT Research team and the Threat Research Center reached out to a possible conclusion, other organizations started discussing similar occurrences of a pattern of amplified attacks being developed at the respective port, 11211.
By the time, Radware identified that the exposure is rather large with a Bandwidth Amplification Factor (BAF) ranging in between 10,000x and 52,000x, predictions turned into harsh reality and in the next 24 hours, attackers targeted GitHub which became one of the world’s largest DDoS attack on record.
The attack was so devastating that it peaked at 1.35Tbps which approximated at an average of 126 million packets per second. As a result, GitHub suffered flawed service for the next 10 minutes until the problem got completely resolved.
The attackers got luckily successful with their attempt at one of the world’s largest codebase, and as a result, numerous similar attacks were followed on for several days damaging multiple servers.
After another attack as large as 1.7Tbps, the world unveiled a ground-breaking fact that they have now entered the era of Terabit Denial of Service attacks.
It triggered security professionals to focus and manufacture some better performing technologies which become the perfect defence against the powerfully sophisticated dangerous DDoS attacks.
Top 4 DDoS Protection Services to Watch out While Searching the Right DDoS Protection for Your Business
Hackers around the world are leveraging the power of adaptive learning which has greatly helped them to identify new and innovative ways to bypass sophisticated DDoS protection defence layers.
However, technological firms have not been sitting idle, they have equally worked hard to stabilize technologies that can easily fend off such powerful attacks.
But, when we talk about DDoS protection, one can find a number of platforms that offer DDoS protection on the go. Several platforms promise to provide the right quality of service; however, they deliberately fail at delivering service which meets the required standard.
Therefore, to make sure your server infrastructures are well protected from some of the most potent DDoS attacks on the Internet, we have taken out some time to perform adequate research.
You need to make sure that whichever security provider you employ for DDoS protection, it provides you with the right tools and technologies so you can deal with the threats efficiently. Looking for something that fits perfectly with your needs? These are the five must-have tools and services that your security platform offers in order to mitigate DDoS vulnerabilities.
SSL DDoS Flood Protection
The majority of the Internet traffic is now encrypted. Mozilla Let’s Encrypt project revealed an amazing insight that more than three-quarter of the global websites are now functioning with the HTTPS protocol instead of HTTP. Some of the markets which greatly support HTTPS are USA and Germany.
However, the rise of SSL has opened new doors to overcoming security challenges related to DDoS. An encrypted request consumes server resources 15 times more than a regular user-generated request. With encryption, the vulnerability allows an attacker to easily infiltrate the website with a smartly designed malicious software holding just a small amount of traffic.
Out of 30% of the malicious attacks taking place last year contributed to SSL DDoS Flood attacks. SSL Flood attacks are the kind of DDoS attacks where a number of requests are sent on a website from several host computers at a single instance. These number of requests ultimately floods the server, and the server ultimately results in suffering downtime.
With the increase in the occurrence of the SSL DDoS Flood based attacks, the need to stabilize a higher level of protection against such malicious activities become eminent.
When you are seeking out the perfect DDoS protection solution for your online business, it is highly advised that you seek out a DDoS protection solution which offers commendable protection against SSL DDoS Flood Protection as well.
Zero Day Protection
Modern day hackers are now adept of hacking into systems that work on traditional security mechanisms. They are capable to bypass any security protocol which most security specialists believe are the best option for their online business solutions.
Nowadays, hackers are capable to hack into systems using a renowned DDoS infiltration strategy termed as the burst DDoS attack. What is the burst DDoS attack? It is the type of DDoS attack which infiltrates a system using a short surge of incoming traffic called traffic spikes.
Most of these traffic spikes consume 70-80% of server resources for a short interval of time. Most attacks are designed to auto-dissolve in less than a minute; however, the attack campaigns may go on for hours, days and even weeks at times.
In order to minimize the level of occurrence, security specialists analyse the incoming traffic from these respective sources and as a result, create a digital signature to block the harmful traffic from coming onto the website.
Even then hackers have found a way to manipulate signatures by studying previous vulnerabilities in the system and bypass all security protocols to damage it.
As a result, security specialists are found head deep in recreating manual signatures at a constant pace. This process ultimately becomes a painstakingly labour-intensive task.
Such attacks which leverages the exploitation of a previously exploit security vulnerability are termed as “zero-day” attacks. Your firewall client plays an important role in keeping zero days threat out of your system.
You also need to understand that getting your tasks done with less number of software applications is a smart way of keeping yourself protected. To keep yourself well-secure from threats like zero-days, you need a security platform which fends off such attacks effectively.
Application Layer DDoS Protection
Application Layer (L7) attacks are malicious behaviours which target the top layer of the OSI model. OSI model is where the common internet requests are generated such as HTTP GET and HTTP POST.
In contrast to only affecting the network layer (L3/4) through DNS Amplification, Application Layer DDoS attacks also consume server resources in addition to network resources.
Unlike Network Layer (L3/4) DDoS Attack Protections, Application Layer (L7) DDoS attack protection isn’t dependent on how much network capacity can a service adjust and entertains, but how your security technology can tackle complex attacks smartly by using the right protection vectors.
It profiles incoming traffic and distinguishes between human and bots. It also identifies which web browsers are hijacked and are used to flood your respective system.
Many online security services promise a state-of-the-art DDoS protection; however, they incredibly fail at delivering one through their WAF. Most DDoS protection services which provide robust protection mechanisms against Application Layer (L7) DDoS attacks come with pricey add-on WAF services which are given separately.
Having something which is optimized and requires less effort to integrate is a better option rather than something which you have to go through, manually.
Behavioural Pattern Protection
In time, DDoS attacks are becoming more refined. This is incredibly becoming difficult to identify whether the traffic visiting your website is a hoax one or a legitimate one. Behavioural issues are more likely observed in the application layer (L7) in an OSI (Open System Interconnection) Model.
Most security specialists don’t have a solution which can resolve sophisticated DDoS attacks. Therefore, in order to stop such attacks from taking place, they use rate-limitation caps as traffic volume thresholds.
However, this approach is a very primitive approach as it does not identify whether an incoming traffic to a website is a legitimate one or not. It rather becomes difficult for security specialists to sieve through the right incoming audience on website platforms.
For example, if you own an e-commerce store and you launch a special discount on holiday seasons, it becomes hard for specialists to identify which of the audience is malicious and which of them is legitimate.
By deploying unsophisticated methods such as rate-limiting mechanisms will only save your website from getting extra traffic. But, here’s the downside, what if the traffic you are trying to keep away from your online store results in holding back some potential paying customers.
However, multiple DDoS protection technologies are now introducing behavioural analysis capabilities. Technologies specially Tcaps Cloud are designed in such a way that it captures normal user behaviour and based on data collection, it confirms whether an incoming traffic to a website is coming from a legitimate user or a hoax one in the future.
Not only do such technologies provide a stronger level of protection, but it also results in creating fewer false positives and will not block any potential incoming website traffic.
Are you looking for DDoS attack protection service which builds a total protection layer around your digital product so you never have to worry about unwanted traffic surges? There are several other attributes that one can discuss when it comes to security; however, some of the above stated are the four must-have DDoS Protection attributes that your security service provider should offer to you as a customer.
