Gravity of DDoS Attack and Smart Tips to Overcome its Threat

Thanks to the ever increasing level of cyber threats, every website deserves a robust DDoS protection for its safe and reliable operations. There is an unprecedented increase in intensity and frequency of cyber attacks that are backed by sophisticated techniques.

Brief insight about DDoS

An attack that results in denial of any service including email or web connectivity to the general users or institutions is considered as DDoS or Distributed Denial of Service attack. These attacks are executed by bombarding the targeted server with a huge volume of requests with an aim to block its actions.

DDoS attack is designed to cause widespread damage to normal day to day functioning of the enterprise or institute. Principal motive of the perpetrators of DDoS attack may be related to a revengeful attitude, or to extract money by causing nuisance or blackmailing. It is also observed that the attacker may not be targeting the website per se because the actual victims are the individuals who are depending on its services.

Whatever may be the motive behind a DDoS attack, the main victim or target of such activity is the server. This can be achieved by congesting the traffic and bandwidth, or attacking hard disk and database storage space with flood of requests. DDoS attack is also found to cause damage to CPU usage as well as server memory.


Need for a sound protection

In the absence of any effective protection, your website is destined to vanish into the blue by going offline. The only choice left to you is to get it up and running by manual methods in the event of a successful DDoS assault. The gravity of such scenario can be overwhelming because it can severely impact your customer base, reputation, and finances.

It must be clear by now that the only way to deal with DDoS attacks is to thwart them before they can inflict damage to your online presence. Prevention is the best defense against most of the potentially dangerous cyber attacks including Distributed Denial of Service (DDoS) assaults.

Reinforcement of bandwidth resource

This may sound to be a far-fetched solution for improving security quotient of the website but a higher bandwidth can certainly help your website sustain a DDoS attack without being pushed offline. Web servers are in a better position to deal with DDoS attack if there is sufficient amount of bandwidth at disposal.

The proof of the bandwidth’s ability in terms of security can be tested by observing websites of large businesses including Facebook or Google that do not suffer from downtime due to DDoS attacks. In addition to a large array of security measures such as firewall protection, the bandwidth of these sites as sufficiently large to reduce impact of DDoS assault.

Detection of an impending DDoS threat

One of the most effective measures to prevent an incoming DDoS attack is to detect any unusual activity. The attack can be mitigated by ensuring that the particular IP address from where the DDoS attack is originating is blocked. The blockade will prevent access of IP address and safeguard your site from the devastation.

DDoS mitigation is the proven and tried method of detection and prevention of the attack by identifying the source of assault in advance. Detection of the attack is also possible with some help from your own Internet Service Provider.

Whenever you are suspecting a possibility of a DDoS attack you can request the service provider to redirect the traffic if any attempt of the attack is detected. Reliable Internet Service providers have been of great help in nipping the DDoS at an early stage. In fact, there are several ISP companies that have designed packages that include these services at an extra cost to customers.

Prevention by detection and mitigation is an ideal way to eliminate possibility of a DDoS attack. These options are worth considering because of the value being provided in terms of securing the site against the major threats of DDoS attacks.

Smart and versatile CDN systems

Content Delivery Network systems not only enhance the user experience by positioning multiple edge servers close to the end users’ locations, but have also a remarkable potential to maintain the website’s performance in spite of a successful DDoS attack.

Thanks to the Points of Presence or edge servers that form the network of CDN systems, these can be used to provide redundancy to maintain online presence of the website in spite of any of these edge servers being impacted due to DDoS attack.

Other servers can be made to provide continuity of website operations till the time the affected server’s performance is restored.

In conclusion

Although DDoS attacks are growing in terms of audacity as well as frequency, there are several ways to deal with such emergencies. The oft repeated cliché of prevention is better than cure aptly sums up the range of solutions available to gain immunity from DDoS.


Reasons to Make Your VPS Servers DDoS-Protected

Any online business can be affected because of the DDoS or Distributed Denial of Service attacks. The risks are manifold when you have virtual private servers. So, it is very necessary to be aware of the risks of DDoS attacks for VPS servers and how you can adopt suitable measures to combat these problems. When a DDoS attack occurs, the site often goes offline. In short, no visitor is able to access your website at this time. The main reason for this inaccessibility is because the attacks cripple the server and the server is unable to respond to the huge volumes of requests. As a result, users cannot access any application running on such a site.

Risks for VPS servers in case of DDoS attacks:

Besides the inconvenience for customers that are not able to access the website, there are many other harmful consequences. DDoS threats can culminate into lethal cyber crimes. Activities like malware activation, virus attacks, network breaches, thefts etc can all take place because of these attacks.

One of the biggest threats is obviously the huge revenue losses on account of these attacks. When critical applications become unresponsive and the entire site slows down, the results can be disastrous for any business. Newstar.biz and Harris Interactive have undertaken studies to show that nearly 84% of businesses have been affected because of at least a single DDoS attack in the past one year. Incidentally, for most of these businesses, the revenue losses came at the time of peak season sales. During peak times, hourly revenue losses because of DDoS attacks can be colossal depending on how large the organization is.

Another reason why VPS servers must be DDoS protected is because of data breach threats. The DDoS attacks usually provide the perfect cover for many lucrative crimes. So, using these crisis situations, hackers can get access to your network; they can even steal sensitive data. So, the security arrangements undertaken by your host must be robust and fault-proof. The provider needs to carry out regular data backups which should be spread across remote servers in different geographical locations.

When there are frequent DDoS attacks on any website, the customers are likely to lose their trust and confidence. Your website and network must be available and accessible at all times to preserve customer trust. When the existing clients are satisfied, they rate your site well and this attracts new clients. When a DDoS attack occurs, the primary target is the critical infrastructure. This automatically affects network performance and causes dissatisfactions amongst buyers. They tend to navigate to other sites and this makes it very hard for the business to get new customers.

When there are frequent DDoS attacks the business reputation is affected. Brand image is the key to success of all businesses and loss of client trust will tarnish their credibility in the market. Whenever the reputation of a business is threatened, rebuilding customer trust takes a long time.

In the recent past, cyber crimes have grown more and more commonplace. The attackers demand ransoms by threatening businesses with such attacks. Usually the criminals send a message that they are planning to launch such an attack and demand a ransom by a specific deadline for stalling it. At times, they even carry out small-scale attacks just to prove that they can do it.

When the applications become unresponsive due to DDoS attacks, the customers start to call up your representatives to demand explanations. To handle these calls and queries, you will need to invest additional funds into creating active help desks. The web hosting services typically face the biggest threats from such attacks. The main reason for this is that every time there is such an attack on any of a hosting provider’s clients, the risks of an attack on the other clients becomes very high since they often share infrastructures in common.

Since every website environment is unique, a host cannot deploy a one-size-fits-all solution for protecting all its client sites against DDoS attacks. So, a solution that works well for a certain website may not work as well for another site. For virtual servers which have firewalls installed, these are meant to guard against such attacks. The firewalls typically have “allow” and “deny” protocols but attackers can gain entry through the same ports which users are granted access from. Some business owners may feel that DDoS attacks will never happen on their sites because their websites are not very popular. The truth is, the attacks are distributed in nature and they will not depend on your organization’s size.

Hackers are usually tempted to carry out DDoS attacks because of the money involved. They can demand ransoms by threatening to disrupt services. So, as a business owner, you must not accept revenue losses and loss of business credibility because of these attacks. The remedy therefore lies in getting a DDoS protected virtual private server. This DDoS-protected virtual server is housed in a server farm which is equipped to combat DDoS attacks. So, these need robust hardware firewalls and a high transfer limit. Using such VPS servers you should be able to successfully prevent protocol-based attacks, DDoS volumetric attacks, specific server or application attacks etc.

Selection of Web-host and Significance of SEO Readiness

Selection of Web-host and Significance of SEO Readiness

There are many website owners or web admins that are not attaching the necessary significance to SEO while launching new businesses. SEO is also an important criterion for evaluation of hosting services while choosing a web host or migrating to a different host.

It is difficult to appreciate the role of web hosting services in ensuring customer retention and enhancing search engine ranking of your website. Therefore one must not leave any stone unturned for making sure that every possible measure is adopted to ensure faster page loading and other attributes for customer engagement.

This calls for an in-depth and thorough analysis of host’s capabilities that boost search engine ranking as well as website loading speed.

Right type of hosting to fulfill your needs

Search engine optimization is a vital feature of a website that is designed to run an online business. SEO cannot only enhance your business prospects but can also help you improve conversion rate via enhanced visitor engagement.

There are three major types of hosting to be considered for implementation of the best SEO practices. It would be relevant to review these individually.

Shared hosting services- These are the most affordable and therefore most commonly used hosting services. However, in terms of their potential to improve your search engine rankings, you will experience certain limitations such as IP address conflict. Moreover, shared hosting also suffers from restrictions in terms of implementation of more software applications as well as configurations. If you have a restricted budget for hosting and need an efficient hosting at down to earth costs, then shared hosting is the way to go. You must make sure that the proposed host has capability of offering you the features that you are looking for.

Virtual Private Server hosting – VPS hosting service runs on a standalone server installation to operate multiple Virtual Machines concurrently on the hardware. Every VPS hosting account holder is offered one VM for hosting website application. VPS offers an enhanced control and provides better privacy and security in comparison with shared hosting. You are free to run your own operating system and can configure the Virtual Private Server to suit your hosting requirements.

Dedicated server hosting- As the name itself suggests, a dedicated server host assigns an independent server to client. This is the most feature-rich hosting type and therefore the most ideal choice for implementation of Search Engine Optimization. It is the most sought after hosting option by large organizations and is the most expensive as well.

Key SEO factors of hosting services

You need to attach special importance to some of the most vital aspects web hosting that can make significant difference to your SEO efforts and general business.

Amount of bandwidth- Bandwidth facilitates ease of data download whenever your visitor is downloading any type of information from your website. Ease of download is directly proportional to the availability of sufficient bandwidth. If there is a low cap on the total availability of the bandwidth, then it is possible that your site will experience downtime during traffic spikes. Some web hosts apply higher bandwidth charges if the account is found to exceed the allocated bandwidth limits. Hence you need to understand your bandwidth requirements according to the traffic and amount of data or information to be downloaded.

Choice of Operating System- For users of VPS or dedicated hosting services, choosing an operating system is a vital consideration. Users of Windows or Microsoft specific applications should select Windows operating system for an enhanced compatibility. In all other situations, it would be prudent to think of Linux operating systems because of excellent economy and stability. Even though there is no correlation between a server software and Search Engine Optimization, one should choose a particular OS to facilitate site requirements rather than boosting the site’s SEO.

Availability of site builder- There is no sense n using the facility of a free site builder provided by your web host, if you have decided to take your SEO seriously by implementing an SEO friendly suite design. Therefore it is better not to attach significance to the feature of a free site builder while choosing your web host. It would be better to get paid services for building your SEO ready site.

Physical location of server- Your website must be served by hosts that have data center in your proximity. Presence of two servers that are located at geographically remote locations can also be an added advantage. Physically close server location can improve site speed in relation with visitors. It can also facilitate geo-targeting to some extent.

Network uptime- In order to improve visibility of your online business, server uptime should be a prime consideration. Downtime can not only impact your site’s business potential but can also harm your search engine ranking.

In conclusion

If you wish to provide a rock-solid foundation for your website operation, then selection of an established and reputed host is the most important step. If you come across negative reviews regarding history hacking, DDoS attacks, or database losses, then it would be better to stay away from such hosts.
