The DDoS attack is always a worry for every business owner, and this has made getting a DDoS protected VPS hosting a top priority for most businesses.

A DDoS attack is a malicious attempt to cause disruption to the normal traffic of websites. This type of attack exploits the limited capacity of the network resources enabling a company's website. What happens during a DDoS attack is that multiple requests are sent to the web resource in order to exceed the capacity of the website to handle multiple requests. The result is that the website won't function correctly.

Apart from getting the right DDoS protected VPS hosting, other things bother many people. Truth be told, it can be confusing but do not worry, you have everything about DDoS attacks explained in this article.

DDoS Protection and Mitigation

DDoS mitigation is the process involved in protecting a targeted network or server from a DDoS attack. This is done by using cloud-based protection services or using specially made network equipment.

Protecting your website from a DDoS attack is never easy. Besides getting DDoS Protected VPS hosting plans, you have to prepare to defend and mitigate the attacks.

Knowing your vulnerabilities is a critical move to take for the protection of your site.

Let's take a look at the steps needed to protect your site.Some of these are to prevent attacks, while some are to mitigate the attacks

  • Purchase more Bandwidth

Ensuring that you have sufficient bandwidth to handle any increase in traffic due to malicious activity is a critical step in preventing a DDoS attack. It also makes your infrastructure resistant to DDoS attacks. This is a preventive measure and not a solution to DDoS attacks.

Having more bandwidth than an attacker has proven to be a way of avoiding DDoS attacks in the past, although amplification is making this less effective.

Increasing the bandwidth increases the hurdles attackers will have to scale before successfully launching a DDoS attack.

  • Protect DNS Servers

Ensure the redundancy of DNS servers. This will prevent attackers from bringing down your website and web servers. DNS, in simplest terms, is like the Internet phone book. It matches the site name of the user seeking the correct IP address, and this makes it an important target for attackers.

A successful DDoS attack on the DNS server can render your site or application unreachable.

Spreading your server across different data centers is also an effective way to make things difficult for your attackers.

To make it more difficult, let the data centers be in the same country but different regions. Also, make sure they are connected to various networks.

Geographical distribution of data makes it difficult for anyone to attack multiple parts of your server. It also enables the unaffected servers to handle additional traffic from the affected servers.

  • Transparent Mitigation

Sometimes hackers launch attacks to make you lose access to your site. Once your site is attacked, use mitigation technology. This enables users to continue using the site, and the jacket might back off if he sees you are not affected by the attack

  • Early Detection

To neutralize a DDoS attack, your website should be able to differentiate between an attack due to the high volume of normal traffic.

For instance, if you are running a promo or release a product, your website can be overwhelmed with legitimate new visitors.

The site might want to stop them from viewing the website content. Previous data, common attack patterns, and IP will help detect attacks.

It will be easy to contain a DDoS attack if you identify it early.

  • Take action

Use anti-DDoS services to differentiate a DDoS attack and a legitimate increase in traffic.

Once you notice your site is under attack, inform your Internet service provider as fast as possible. This will determine if your traffic can be rerouted. You can also have a backup ISP.

ISP's will use black hole routing to reroute your traffic.

Some services render DDoS attacks ineffective by dispersing the traffic among a network of servers.

Intelligent routing of traffic is an effective way of mitigating DDoS attacks as it will break the traffic left into manageable sizes.

  • Network Hardware Configuration against DDoS attacks.

A simple configuration of your network hardware can help you prevent DDoS attack. For instance, if configuring your router or firewallto drop incoming ICMP packets or drop DNS responses that come outside of your network will help prevent some DNS and ping based volumetric attacks.

If you have the knowledge or youcan get someone who is tech-savvy, configuring your firewalls and routers is another effective method of mitigating DDoS attacks. Firewalls and routers can be configured in a way that will make them reject bogus traffic.

Additionally, ensure your firewalls and routers are up to date with the latest security patches.

  • Anti-DDoS hardware and software modules

In addition to having your server protected by firewalls, you must use load balancers.

You can prevent DDoS attacks by adding software modules to another web server software.

You can use hardware modules that have software protection against some DDoS attacks, such as SYN flood attacks.

  • Consider AI

With the fast advancement of technology, AI is providing services humans provide, sometimes even more efficiently. While we are used to the current firewall defenses and intrusion system, new systems are being developed using AI.

AI systems can route internet traffic to the cloud in no time where it is analyzed. Also, illegal traffic is blocked.

Also, AI self-learning capabilities would be useful in predicting and identifying DDoS patterns.

  • Secure your IoT devices

This is a preventive measure for consumers. Ensure your computers have trusted security software to protect your device from becoming a part of a botnet.

Also, make sure your IoT devices are formatted for maximum protection.

Devices with weak passwords are vulnerable to attacks, so secure passwords should be used for all your IoT devices.

DDoS Defense Types

There are different defensive responses to DDoS attacks. Detection of attack, use of response tools, and all the steps listed in the preceding section is what these defense types utilize. It is important to note that there are different types of DDoS attacks, some are cloud based, volume based and so on. As such you have to identify the type of attack, to know which response will be best to use.

Here are some prevention and response tools.

  • Application front end hardware

The primary function of this hardware is the analysis and identification of data packets as they enter the system. The hardware can carry out this function because it is placed on the network before traffic gets to the servers.

Application front end hardware identifies and classifies data either as regular, dangerous or priority, and there are over 20 bandwidth management vendors.

  • Blackholing and Sinkholing.

Blackhole routing keeps a targeted website from crashing by redirecting traffic into a null route when there is excessive traffic.

However, the downside is that sinkhole is not efficient for severe attacks, and sometimes both legal and illegal traffic will be rerouted.

  • IPS based prevention

If an attack has signatures linked with them, then IPS based prevention is very useful. These kinds of attacks have legal content but malicious intent, so IPS, which works on content recognition, cannot stop behavior-based DDoS attacks.

DoS attacks can be detected and blocked by ASIC (Application Specific Integrated Circuit) based IPS because of their processing power. Also, it analyses attacks at the granular level and acts as an automatic circuit breaker.

An RBIPS (rate-based) blocks DoS attacks by granularly analyzing traffic and monitoring traffic patterns to detect any traffic anomaly. It blocks the Dos attack traffic and allows normal traffic to flow.

  • DDS based defence

DDS (DoS defence system) based defense will block attacks that are connection-based. It also blocks attacks with legal content but malicious intent. A DDS takes care of rate-based and protocol attacks. DDS are built in a way that identifies and obstructs a DoS attack easily.

  • Application-level Key Completion Indicators

This is a technique that identifies the path of value inside an application and monitors the request progress on this path through markers. These markers are referred to as Key Completion Indicators.

This approach is based on application layer analysis. This indicates if incoming bulk traffic is malicious or not.

The Key Completion Indicators identifies normal behavior in the application, and once there is abnormal behavior, it is easily identified.

An added advantage of this technique is that in an elastic cloud service, where extra workload may mean you have to pay more to your cloud service provider. This method can help in scaling back the server to protect from economic loss

  • Firewalls

To take care of simple attacks, you can add a simple to a firewall. This blocks the attackers' traffic based on protocol or originating IP addresses.

However, simple rules are not efficient in blocking complex attacks.

Also, routers might be significantly affected before getting to the firewall. This is because the firewall is sometimes too deep in the network hierarchy.

Additionally, quite a number of security tools do not support IPv6 and, in some cases, might not allow it to be configured well. This makes it possible for firewalls to be attacked.

  • Switches

Switches have ACL (Access Control List) and rate-limiting capability.

Additionally, some provide system-wide rate limiting, deep packet inspection, delayed binding, and bogus IP filtering features that help in detecting and remediating DoS attacks.

  • Routers

Just like switches, routes possess some ACL and rate-limiting capability and are also set manually although most routers can be overwhelmed when attacked.

  • Upstream filtering

In upstream filtering, all traffic will pass through a cleaning center, which separates malicious traffic and sends only the normal traffic to the server. This is done by using different methods such as digital cross-connects, tunnels, direct circuits, proxies.

DDoS Protected Virtual Private Server Plans

While there are traditional methods to take care of DDoS attacks, it involves buying equipment. This is usually on the high side in terms of cost. It would be best if you also had a network that can resist an attack. Even at that if the attack is large enough, your network infrastructure upstream can be taken out. Once it is taken out, all onsite will not be effective. Before the purchase of a DDoS Protected VPS Hosting service, there are some things you should look out for.

  1. Scalability - Any solution you will choose has to be scalable and adapt to growing business needs. It should also be able to respond to the increasing size of DDoS attacks. In the past, there have been attacks larger than 2TBps, and that is a trend that does not seem to be fading away
  2. Flexibility - Another feature you should look out for is flexibility. You should have access to create rules and policies that will let your site adapt to incoming threats quickly. This feature is critical in keeping a site online during an attack
  3. Reliability- Your DDoS mitigation solution should be reliable. Having a high uptime rate and site reliability engineers is one thing you should check well before deciding on a DDoS solution provider. Usually, an efficient DDoS mitigation solution provider should have the site engineers available 24/7 to keep the network online and detect new threats.
  4. Network size- A large network with extensive data transfer makes it easy for a DDoS mitigation service provider to analyze and respond to attacks smoothly and efficiently.

Although DDoS protection is not something you need all the time, however, it should be reliable when you need it.

Brands such as Vultr, Inmotion, A2hosting and Hostinger offer cheap DDoS Protected VPS Hosting Plan. With prices ranging from as low as $2 to $5 a month.
