DDOS or Distributed Denial-of-service attack is the hacking capacity allowing one to deny rightful clients. It makes the server busy in serving fake requests which intentionally damages the performance of the server. It affects numerous machines and hampers the benefits of the entire web community. This is truly the most challenging web issue these days. The hacking process just requires the installment of the DDOS programming on a specific gadget. 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. The solution is DDOS Protection Hosting.

Some DDOS assaults include flooding someone with messages to fill the drive of their PC. In this article, we will discuss DDoS protection.

DDOS Protection Hosting is priceless now

Recently, there have been more cutting-edge instances of assaults, one of which is 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. Moreover, in a more awful situation, stop its capacity and close the entire framework down. DDOS Protection Hosting can stop these assaults.

 

Dangerous DDoS assaults

DDOS assaults bring intense dangers. It 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 a while can face assault 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. Indeed, it will influence your web hosts; utilizing your allocated data transfer capacity. DDOS Protection Hosting can help organizations with such scenarios.

 

Because of all these threats, DDOS is important. We are talking thousands or even much higher number of dollars traded off of your business. To avoid this you have two options – either purchase your own hardware which can really be expensive or rent the gear. Leasing is cheap. Rather it can really make you spend a lot more over the long haul. Moreover, you will never feel its significance until you suffer from it.

Protecting against DDoS Attack

One of the ways to protect your website from a DDoS attack is to have more resources than the attacker. If a network can provide more resources 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 save from such attacks. To understand this, we can take a simple analogy.

In social insurance, providing healthcare to everyone is expensive. However, all do not need healthcare coverage at the same time. This also means that for a large network, there is a high chance for people to 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 attacks better than small companies.

Choosing a dedicated Server with Advanced DDoS Protection Hosting

A dedicated server provides more bandwidth, security, 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. In which a large number of UDP packets are sent to the targeted server which blocks all the resources. As a result, the website goes down. These attacks are mostly seen 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.

Benefits of DDoS protection

There are many benefits of having a DDoS protection service, which we are going to discuss below.

Maintains Reputation

The DDoS attack is a destroyer of reputation. A DDoS attack on a large organization will affect the trust and confidence the customers or users have in the institution. Even smaller organizations will have a similar effect, especially those who are trying to build their reputation.

A single attack on a customer may ruin the reputation the organization has built for many years since its existence. That’s why all businesses must do all they can to protect themselves against DDoS attacks. Otherwise, they stand a chance of losing the trust and reputation they’ve built over the years.

Save cost

The aftermath of a DDoS attack is usually more painful financially. Those businesses that have been attacked know how much they have lost and the cost they have to bear. When a business experiences downtimes or traffic is blocked, it means the customers would not be able to reach the network and carry out their transactions with the business. The cost to the business will keep rising as long as the attack lasts. But when you have set up to prevent or mitigate such attacks with a proactive approach, the attackers would stay off. Even if they succeed in any way, the damage will be very limited as the mitigation system will pounce immediately if there is an attack.

Maintains customer experience

The customer is the king in any business. So, when a website does not perform to the expectation of the customers, they can walk away and move over to competitors. Competition in cyberspace is very fierce, and customers within this space can get frustrated easily. As most of the business activities are transacted online, they are not bound by loyalty or sentiments when making decisions.

A DDoS attack is capable of turning your customers away. When you take up DDoS Protection Service, it will prevent the attack that would have cost you your customer faith. A network attack by DDoS will result in loss of assets, data, among other things. The monetary or financial value will be too high when the business wants to repair, rebuild, or purchase new equipment. Computers, routers, and other hardware components will take lots of money to purchase and replace. But you can prevent all these by subscribing to a DDoS Protection Service.

Block Spoofed IP Address

‘Spoofing’ refers to presenting the wrong facts in a presentable and decorated way. Often, hackers spoof the IP Address. So the user’s firewall and other anti-hacking applications do not suspect an attack. To avoid such attacks, you can do the following:

• Create an ACL (Access Control List) which will deny all traffic with the source IP which is 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.
• Monitor both inbound and outbound traffic.
• The router and switches can be configured to block packets from outside your network.
• To allow only trusted hosts to do the encrypting sessions.

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 that alerts you in case of unusual traffic on your website. For example, if the normal visit number is around 500 per 10 mins, you should receive an alert if traffic is 4000 per minute.

Secure Connected Devices

In recent times, 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 the passwords of the devices regularly. Switch off the devices when they are not in use. And verify before connecting.

Secure VPS Hosting

A dedicated server is usually very expensive. It might not be a good idea if you have a small business. But at the same time, protection from DDoS attacks 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; its own operating system, and IP. You also have full console access. It enables you 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 on 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 IPs.

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 there is no application, replies with a ‘Destination Unreachable’ packet. This process uses up the host resources, which leads to inaccessibility. A DDOS protection server can really help from UDP attacks.

ICMP Attack

In an ICMP attack, the target resource is flooded with ICMP Echo Requests. Then the packets are sent very fast giving no time between replies. This type of attack consumes both incoming and outgoing bandwidth. 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. The DDoS protection server can prevent these SYN attacks.

Slow loris

In slow loris, 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 the unavailability of the server for legitimate users. DDoS-protected Web Hosting can prevent it.

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 service will be really helpful to protect from HTTP flood.

Choosing a DDoS mitigation appliances provider

Let us see the features you should focus on before investing in any DDoS provider.

Processing capabilities

In addition to network capacity, you should consider the processing capabilities of the provided mitigation solution. 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 your entire business. So, while choosing a mitigation service, it is important to know if it provides pre-emptive detection. So, test this during the service trial.

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 that these data centers connect to different networks. So, there is no chance of failure. This decreases the chance of an attack on your whole server at a certain point in time. The unaffected servers can take up some traffic from the affected servers.

Ping of Death

The attacker sends many malicious pings to the target server. It floods the recipient with such IP packets and soon overflows its memory buffer which leads to a denial of service for original packets. If you are on DDoS-protected Web Hosting then you may be safe from such scenarios.

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, this will enable the users to access your website. It will not show them outdated cache content or error screens. If the hacker finds out that the users have no effect of the DDoS attack, he might not come back. Many anti-DDoS service providers are already using this technique.

Purchase more bandwidth

This is a preventive measure against DDoS attacks. Having more bandwidth is to make prevent DDoS attacks. That can handle the increase in traffic which may be the reason for 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 decreases the chance of DNS or ping-based attacks. Using a proper network configuration you can have DDoS attack prevention.

Network layer mitigation techniques

Different service providers have different techniques to protect the network layer from DDoS attacks. A 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 detect 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 pass through a security service. It detects the Malicious IP’s 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.

Protecting Secondary Assets

Your network infrastructure includes web servers, DNS Servers, FTP servers, email servers, ERP platforms, etc. In the case of a DDoS attack, it may also affect other assets. DNS is the most common attack target. Everything fails in case DNS fails , DDOS Protection Hosting is importan to mitigate this issue.

Pricing

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 for 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%. Do not 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.

Conclusion

I hope there is no room for doubt now. As DDoS attacks have increased in recent times, it’s up to business organizations to find means of protecting their systems and networks against these attacks. This is because it’s always better to prevent than to repair. DDOS Protection Hosting is a great tool to prevent this issue.
