Why Cloud need to be more secure
Whether SME or an enterprise, if infrastructural demand is very large for an application the in-house cost would be higher. So, it is a must to choose cloud services. The fundamental focus of every customer or enterprise is security of sensitive data no matter where it is. The growing trend of cloud adoption by several companies irrespective of size had shown a new way for breaches. Of course, huge and high profile enterprises have already adopted cloud security in their agenda. Now it is time for small and medium scale businesses to follow.
Since cloud storage involves storing of sensitive data outside your organisation, you should demand high security, recovery plans, transparency and much more to make your access simpler and safer. The main security issue any customer of cloud service finds is lack of control over infrastructural computing. When a business moves applications to a cloud it loses control access to logs, patch management, server access etc. Though this can increase cost savings, you may have to loose administrative access.
What makes cloud more vulnerable is the sharing of a single web application on a single server among different users. When the entire data from different users enter the servers they might co-mingle and privacy should be compromised here. Of course, there are prevention measures to prevent this; it is not that difficult for an attacker who is your co-user of cloud on same platform. So, just choosing a cloud service provider doesn't ensure you security, your cloud service provider should submit you time to time reports on vulnerabilities and educate you about evolving threats etc.
According to IBM, by 2015 revenues from cloud innovations are expected to cross one trillion dollars where half of it will be from SMBs. This is quite enough to indicate the capacity of SMBs and how important security is for them. It depends on your requirements whether you need a private cloud? When it comes to which is secure i.e. private or public, private cloud has some benefits over the other. Some benefits of private cloud over public if at all you can afford are;
1. Your data can be live and you will have complete access to it all the time.
2. Your safety i.e. Data security is entirely your responsibility.
3. You will have total control and know whom you have granted access.
4. You will be responsible for defending attacks and securing your network and you'll be responsible for threats from your customers.
5. You can know where your data resides exactly which you can't know in a public cloud.
What should you consider
Insider attacks also might affect your data on cloud. An improperly designed environment may allow an illegal administrator to misuse your data. Since competition is playing a crucial role in emerging markets, your competitors may spy on your business by sending their employees into your business. Also, cloud is not used by a single user; it may be used by an attacker to make a DDoS attack. This DDoS attacks bring huge traffic to server you rely on therefore making your service unavailable to users who really deserve it. Who knows attacker might be using the same cloud which his target is using. So, you need to be very clear about the security measures offered by your cloud service providers.
No matter who is your cloud service provider, he should provide you complete access to processes being conducted in cloud. So that you can manage and audit those processes even using using a third party. Since you will not have the infrastructure nearby, you should have to call service frequently for support. Therefore Service Level Agreement called SLA will be a major factor to be considered before opting a provider.
