What is DDoS Attacks?
A DDos(Denial of Service DoS attack) is a dangerous endeavor to affect the chance of the targeted system, such as an application or a website, to authorized end users. Generally, attackers produce large amounts of requests or packets ultimately destroying a specific target system. While in case of a DDoS attack, the attacker utilizes various controlled or compromised sources to create the attack.
The DDoS attack can be differentiated into layers of OSI(Operating Systems Interconnection) model. It consists of 7 layers, out of which Layer 3(Network), Layer 4(Transport), Layer 6(Presentation), and Layer 7(Application) are important.
While mitigating the DDoS attack, the layers are to be separated into groups which together form an infrastructure layer.
Had a website running by own, then managing the service online for a preferred company is a must. If there is some idea of how the attack comes and have some potential that brings the lost revenue.
A Catastrophic action
Getting affected by a DDoS attack is a catastrophic action. When an organization is attacked by a DDoS attack, the cost they charge is nearly $100,000 per hour as per the study.
Anti DDoS software modules are available so as to reduce the burden in these attacks.
Lack of reputation, branding, degradation eventually decreases the growth in business. Indeed, by many experiences, it is suggested to invest resources which prevent these attacks. Not exactly but for an optimal level, the risk might be reduced.
For having survived from these attacks, simply follow a few preventions that will address DDoS attacks.
Below are the 5 Tips to Protect a Website:
- Content Delivery Networks
When a distributed disclaimer of service has been attacked, people generally look after using a CDN for eradicating it. Simply adding a CDN to the website means hosting a website with multiple IP addresses. In that case, many minor and major attacks like DDoS attacks can be succeeded. Even more, a backup for the data is also available which would be running back until addressing the right reason behind the cause.
Adding CDN remains as the cost-efficient and convenient method of getting rescued from DDoS attacks. Most of the small businesses choose this option as their first option. All their websites can be bounced back with the benefit of reducing the latency to the website from the unknown and remote locations.
- Create Redundancy
For making or encouraging hackers to attack successfully is a tough task. Launching a DDoS attack against the servers is also a difficulty. Make sure to spread them across many data centers having a better balancing system to manage and distribute the traffic accordingly. In fact, these data centers can be of other countries or at least other regions of the country.
For making this effective, ensure to have all the data centers interconnected to multiple networks. Instead, check whether there are any bottlenecks or failure that might make failures in the network further.
However, managing and distributing the servers topographically or geographically will make attackers feel risky in attacking between the servers or leaving a few servers unaffected. This can also include risk in taking some traffic that affects servers that are handled normally.
- Strengthen the Bandwidth
Probably, this might not stand as the best way to protect the website from DDoS attack. Higher the bandwidth, higher the risk of having more distributed denial attacks. All these may not be handled by the server without neglecting. However, most of the big and bundled websites like Facebook, Amazon, Google, Yahoo go down due to such deniel DDoS attacks.
This is likely to happen because these websites have more bandwidth which is more than the typical DDoS attacks that can be compromised. This is because these have a strong security than usual. Additional bandwidth may costs higher than usual so implementing the limited resource in the right way is more suggested. But the basic comparison is that how much spent is larger than the DDoS attack on the website.
- Employ a DDoS specialist
When everything failed, employing someone who is an expert in providing internet security to the site owners is one of the best fit. There are many services in the market like Neustar, Incapsula, and Akamai which can help with an additional investment. With these services, there is always an added technology which is not available on the own. keep in mind that, as the business expands in the future this option is more viable.
- Deploy anti-DDoS software and hardware attributes
All the servers need to be surrounded and protected by the network firewalls, the specialized applications for the firewall that probably utilize the load balancers. Nowadays, most of the vendors include software protection setups against the protocols like SYN flood attacks which are monitored in knowing the status of how many incomplete connections are been observed that are flushing while the reach is outweighed that the regular threshold value.
Some of the websites employ software modules that are responsible for protecting the DDoS attacks. A few software modules exist, which may lower the attacks that are keen in separating the connections from the web server and holds them tightly until a new one opens with a partial request to accept.
As observed above there are many methods and ways available for protecting the websites from unnecessary DDoS attacks. It is all that depends on how particular the need is and the investment that is endeavored for enabling the highest security. However, with the increase in the powerful DDoS attacks, there are many new and updated software and recurring solutions have been introduced into the internet market. Anti-DDoS security software has been provided by different companies who are responsible for reducing the cause.
Select the software or solution that particularly need to address and solve the denial of the service in the coming future. Approach for multiple reasons and solutions rather sticking to only one.
