Cloud computing has changed the methodology of how firms use technology to interact with their clients, suppliers or partners. Business organizations such as Yahoo and Google have already placed the majority of their IT resources in cloud because, by doing this, they can get rid of many of the constraints on these resources from using the historical computer environment, in both cost effectiveness and space efficiency. There are a number of forms of cloud computing, and these can be broken down into public or private, and hybrid.
If the future of computing lies in the ‘clouds’ then it is for very good reason, and this is the shift of workload from local computers to a cloud network. According to our intelligence degree, the user’s computer only needs to be able to run the interface software and the cloud network will take care of the rest. Most people already have had an experience of cloud technology, and if you have opened an account with Hotmail or Gmail your messages are not stored on your own computer, rather you log into your e-mail account to read your messages. The major problem with putting information, which is often sensitive, in cloud will be security, and below is an explanation of the three most fundamental ways of approaching cyber security.
Separation of roles that overlap in hybrid systems
The problem with the operation of hybrid systems is that even though it is vital to separate any roles that are overlapping, this is not so easy to do, and the risk to security can be laid firmly at the door of these loopholes in the system. A central server will more than likely be accessible by a number of different administrators, and each one of the administrators will have their own accounts in the public sphere. When these accounts come up against phishing, the secondary accounts of administrators will be the most vulnerable and result in serious security problems for the central server.
The solution here is to limit the centralized administration to the absolute minimum, and ring-fence those individuals to minimize any co-relationships between those who have other accounts elsewhere. It is of fundamental importance to realize that, in today’s climate the cloud hybrid has security issues not only externally but from also from internal users. Firms must, therefore, not be blinkered and just look for security attacks from outside, but must be totally aware of the risks within.
Individual infrastructure security
Another security approach is to relegate it to individual infrastructures. The options here are either to have a VPN virtual pathway or to use the public network. Of the two, the VPN is the safer as it gives an independent road between outside and inside infrastructures. The result of this means that even though there may not be 100% access to public systems, the upside is that data coming in is directed through a system of checking.
The other way is to let the public system deal with any security threat, which means that data moving across the personal firewall will be secure. This solution, unlike the VPN, gives bigger access to resources that VPN restricts.
Combination security methodology
The third and most balanced approach is to have a combination of internal and external and get the best out of both systems. This is a flexible solution that has the advantage of being able to switch strategy if one system fails. The fantastic thing about utilizing a hybrid security system is the relocation benefits. There is the possibility to switch between security providers or even get the benefit of more than one at the same time.
Security systems in cyber space are moving forward at an extremely fast past, and the future holds a certain amount of inevitability in using a combination of private and public cloud systems. With bigger and more intense breaches in internal security, companies are looking to external solutions more than ever before.
