DDOS somewhat fixed, DDOS Protection Hosting.

DDOS or Distributed Denial-of-service attack is the hacking capacity allowing one to deny rightful clients and make server busy in serving fake requests which created intentionally to damage the performance of the server.

It affects numerous machines and hampers the benefits of the entire web community. It is truly the most challenging web issue these days. The hacking process just requires the installment of the DDOS programming on a specific gadget, and when the real client does a certain undertaking or charge on the gadget where the product had been placed, there is an automatic trigger sending bundles of requests out to the majority of the machines to be infected.

Some of the primitive instances of DDOS assault include flooding someone with messages to fill the drive of their PC.

DDOS Protection Hosting has been made priceless

Recently, there has been more cutting-edge instances of assaults, one of which is through organized PCs. Clients can be denied access to FTPs, space name administrations, and even access to the web. These assaults can originate from diverse sources, either inside or outside a certain machine or system. They assault the machine either by gobbling up its transfer speed, memory, or different assets and in a more awful situation, stop its capacity and close the entire framework down. These assaults can be stopped using DDOS Protection Hosting.

You may be encountering an assault by experiencing seriously deficient system associations, you could get blocked from being able to view a particular site, all other sites whatsoever, or as mentioned earlier you could be a victim of violated message privacy.

DDOS assaults bring intense dangers and can bring about a ton of harm to a certain client, particularly if it affects potential business. Keep in mind that a business site or stage that has been operating safely for quite a while can be assaulted within a couple of minutes. This can really bring business latency down so new clients would not be able to get access to your site and systematically making you lose deals. Indeed, even your web hosts can be influenced; utilizing your allocated data transfer capacity is a prime route through which facilitating organizations are assaulted. DDOS Protection Hosting can help organizations from such scenarios.

Because of all these threats, it is really logical why DDOS insurance is truly essential. We are talking thousands or even much higher number of dollars traded off of your business. In avoiding this you have two options – either purchase your own hardware which can really be extremely extravagant or rent the gear. Leasing does not make it all too much less expensive; rather it can really make you spend a lot more over the long haul, particularly in the instance that you settle on facilitating arrangement with simply almost no scope, and you will never feel its significance until you turn into a sufferer.

DDoS protection hosting is secured from speed, support and consistency. The anti ddos solution connected with their hosting. The DDOS Protection Hosting has deployed individual platform-level anti ddos firewalls on all WordPress, DDoS protected servers automatically and they also use top-notch security hardening techniques to make sure that all servers stay protected.

DDoS attacks were reported in early 2000 when it was first documented. Amazon and eBay suffered a loss of around $1.7 billion through this type of attack were very new.  Today, the attacks have become more sophisticated and the damage that can be done has also increased many-fold. However, the advancement in the technical world has led to many advanced ddos protection techniques against these attacks.

Protecting against DDoS Attack

One of the ways to protect your website from a DDoS attack is you need to have more resource than the attacker. If a network can provide more resource than the attacker, the website is up and functional, otherwise, it goes down.

However, the attackers use technologies like DNS amplification, IP spoofing and a distributed network which will throw much more requests than your website can handle. One way to protect an IP is to put an intermediate layer between the attacker and the website. This layer is distributed over a large network. DDOS Protection Hosting can help from such attacks. To understand this, we can take a simple analogy.

In social insurance, providing healthcare to everyone is very expensive. However, all do not need healthcare coverage at the same time. So, if each one contributes a little, then healthcare costs for a few can be paid out. This also means that for a large network, there is a high chance to people pay a little amount, and the services can be provided to those who are in need. But if the network is small, each one has to pay a large amount, which very few would want to pay.

So, large companies can handle and protect against DDoS Attack better than small companies.

Choosing a dedicated Server with Advanced DDoS Protection Hosting

A dedicated server provides more bandwidth, security control, and more flexibility. This is definitely an expensive solution but outweighs the monetary damage you may have to face in case of a DDoS attack.

DDoS protected dedicated servers provide advanced ddos protection against UDP (User Datagram Protocol) attacks where a large number of UDP packets are sent to the targeted server which blocks all the resources and the website goes down. These attacks are mostly experienced in Minecraft dedicated servers, game servers, and enterprise servers. Dedicated servers come with dedicated RAM and CPU for a single user which they do not need to share with others. The customers have the full flexibility in choosing and installing OS (Operating System), applications and plugins. Some ddos protected dedicated servers also give users the power to whitelist the IPs and ports which they consider safe.

Blocking Spoofed IP Address

‘Spoofing’ refers to presenting the wrong facts in a presentable and decorated way. Often, hackers spoof the IP Address so that it is not suspected by the user’s firewall and other anti-hacking applications installed. To avoid such attacks, the following things can be done:

  • Create an ACL (Access Control List) which will deny all traffic with the source IP that has been detected as malicious.
  • Use Reverse Path Forwarding (RPF) or IP Verify. Reverse Path Forwarding is a method prevalent in modern routers which ensures multicast packets are transferred loop-free in multicast routing. This helps to prevent spoofing of IP.
  • Both inbound and outbound traffic should be monitored.
  • The router and switches can be configured to block packets from outside your network.
  • Encrypting sessions can be done to allow only trusted hosts.

Monitor Traffic Levels

The sooner you get to know about a DDoS attack, the faster you can act on it. So, as a preventive measure, you can set up a trigger which alerts you in case of unusual traffic on your website. For example, if the normal visit number is around 500 per 10 mins, an alert should be received if traffic is 4000 per minute.

Secure Connected Devices

In recent time, IOT (Internet of Things) devices are on the rise, but this also means hackers are getting some connected platform through which they can impact a brand. So, to avoid such issues, change passwords of the devices regularly, switch off the devices when they are not used and verify before connecting.

Secure VPS Hosting

A dedicated server is usually very expensive and might not be a good idea if you have a small business. But at the same time, protection from DDoS attack is important. In such scenarios, you can opt for a secure VPS connection.

In a secured VPS, your website has an independent portion of the server; own operating system, and IP. You also have full console access, which enables to remove any malware.

Remote Black Hole

In the event of an attack, all the UDP traffic can be transferred to a remote black hole where the traffic is dropped based to the IP address and destination. To set this up, a null route is created and on the management, router configuration is done to route traffic from particular IP’s.

Types of DDOS Attack

Some of the common types of DDoS attacks are:

UDP Attack

A UDP attack refers to flooding the target server by UDP (User Datagram Protocol) packets. The attacker floods a remote host server with many requests on some random ports. This leads to the host checking the application at the port, and when no application is found, replies with ‘Destination Unreachable’ packet. This process uses up the host resources, which leads to inaccessibility. Ddos protection server can really help from UDP attacks.

ICMP Attack

In an ICMP attack, the target resource is flooded with ICMP Echo Requests and the packets are sent very fast giving no time between replies. Both incoming and outgoing bandwidth is consumed by this type of attack. As the targeted server attempts to reply to ICMP requests, this results in overall slowing down the system. Ddos protected web hosting can help to prevent ICMP attacks.

SYN Attack

In an SYN attack scenario, the attacker sends many SYN requests, the SYN request initiates a TCP connection with the host, and the host sends an SYN-ACK response. Now the requester does not send any response to the SYN-ACK response or sends more SYN requests from a malicious IP. These SYN attacks can be prevented using Ddos protection server.


In slowloris, the attacker makes a connection to the target server by sending partial requests. It constantly requests by sending more HTTP headers, but no request is completed. The target server has many open false connections at a time, which leads to unavailability of the server for legitimate users. This can be avoided with the help of ddos protected webhosting.

HTTP flood

In an HTTP attack, the attacker sends many HTTP Get or Post requests to bring down the server. This requires no packets and less bandwidth than other types of attacks. Often, the server or the applications allocate maximum resources available to each request. Ddos protection server will be really helpful to protect from HTTP flood.

Ping of Death

The attacker sends many malicious pings to the target server. The recipient gets flooded with such IP packets and soon overflows its memory buffer, leading to a denial of service for original packets. If you are on ddos protected webhosting then you may be safe from such scenarios.

DDoS Mitigation Strategies

DDoS Mitigation Strategies refers to a set of ddos attack prevention procedures which can be adapted to prevent a website from a DDoS attack.

Protect DNS Servers

Attackers can attack the DNS server and bring down your website. So, it is important that the DNS servers have redundancy. Also, you can consider spreading the servers across various data centers. These data centers can be located in different regions of the same country or maybe in different countries. It is necessary these data centers are connected to different networks which work with no point of failure. This decreases the chance of an attack on your whole server at a certain point of time, and the unaffected servers can take up some traffic of the affected servers.

Transparent mitigation

Hackers believe that the users of your website lose access in case of a DDoS attack. So, it is important to adopt a mitigation technology which will enable the users to access your website without showing them outdated cache content or error screens. If the hacker finds out that the users are unaffected by the DDoS attack, they might not come back. Many anti ddos service providers are already using this technique.

Purchase more bandwidth

This is a preventive measure against DDoS attack. Having more bandwidth is to make sure ddos attack prevention that can handle the increase in traffic which may be caused by the DDoS attack. However, this was more beneficial in the earlier days because now, the hackers use amplification to flood requests to your website.

Set Network Configuration

You can configure the router and anti ddos firewall to drop DNS responses from outside the network and drop probable malicious ICMP packets. This helps to decrease the chance of DNS or ping-based attacks. Using a proper network configuration you can have ddos attack prevention.

Anti DDOS solutions

In addition to the anti ddos firewall, you can use load balancers as an anti ddos solution. For example, Apache 2.2.15 comes with an additional software module which protects them against application layer attack. This helps to keep the connection to the server functional by sending partial requests until the website is up again.




Choosing a ddos mitigation appliances provider

Network capacity

Network capacity determines the scalability of your network in the event of an attack. It is measured in Gbps (gigabits per second) or Tbps (terabits per second).

For example, a 1 Tbps network can almost block malicious traffic of around the same size. While choosing a mitigation service, it is important to consider the network capacity. The cloud-based mitigation services provide much more network capacity than physical DDoS mitigation appliances. For on-premise DDoS mitigation appliances, the hardware capacity and organization’s network pipeline are the key points.

Processing capabilities

In addition to network capacity, the processing capabilities of the provided mitigation solution should be considered. This is called forwarding rate, measured by Mpps (millions of packets per second).

Many attacks can range up to 200-300 Mpps. An attack exceeding the mitigation provider’s processing power will bring down your website, so it is better to be aware of the limitations.

Time to mitigation

Most attacks put down the website in a couple of minutes and the recovery takes hours. This impacts the customers and can impact the business of your organization. So, while choosing a mitigation service, it is important to know if it provides pre-emptive detection. So, it is recommended to test this during service-trial.

Network layer mitigation techniques

Different service providers have different techniques to protect the network layer from the DDoS attack. Few of them are:

  • Null Routing: Null routing routes all traffic to a fake or non-existent IP. The disadvantage of this technique is many legitimate visitors can be detected as malicious.
  • Sinkholing: This technique diverts the traffic away from the target. This also leads to some false positives similar to null routing though in lesser proportion. It is also ineffective in case of IP spoofing.
  • Scrubbing: In scrubbing, all inbound traffic is passed through a security service. Malicious IP’s are detected based on the header content, size, type, etc. The challenge in this type of system is to maintain a good inline rate without impacting authentic users.

Application layer mitigation methodologies

In the application layer, the attackers spoof the IP’s of original users to penetrate through the security measures. To avoid such an attack, it is important that proper filtering between requests are done. This includes inspection of HTTP/S headers and pattern and IP information. Some services use different testing strategies, like checking the request to parse JavaScript and store cookies.

Also, services should not overuse captchas and other authentication techniques which disturb safe users. There are many anti ddos services available which are implemented in the application layer to minimize the attacks.

Protecting Secondary Assets

Your network infrastructure includes web servers, DNS Servers, FTP servers, email servers, ERP platforms, etc. In case of a DDoS attack, other assets may also get affected. DNS is the most common attack target and everything fails in case DNS fails.


Anti DDoS service price is either monthly or pay-as-you-go. The pay-as-you-go is dependent on the bandwidth affected (like 50 Gbps/month) or website downtime (like 12 hrs/month). As it is not known how much time the attack will last, it is better to opt for a monthly service.  The pricing of the mitigation provider also depends on the SLA (Service Level Agreement). It is advisable to check the following:

  • Uptime Guarantee: The best case is generally 99.999%. It is not recommended to choose a provider with a rate of less than 99.9%.
  • Levels of Protection: The service provider’s SLA should mention the types of attack, duration and the extent covered by them.
  • Response Time: The response time in case of a DDoS attack is one of the crucial factors.
