Does The Flat Model Offer Enough Security In Cloud Computing?
The kind of network model that one employs to compile, distribute and exchange data determines the security of its passage through the Internet. This brings the question of whether the flat model can serve as the best security option for cloud computing. This model, first of all, helps to create a more direct relationship between the data provider and the recipient compared to tiered structures. Tiered structures are networks that have not only the access and the core but other integrated endpoints within the distribution path. The flat system only has the access and end points. It virtually eliminates the necessity of intermediaries, which leads to fast and more reliable information retrieval.
The basic question is: is it still the way to go when thinking about cloud security?
Security in flat cloud
The tiered networks, for one, have always relied on data providers to install safety measures. They cut access to data that is considered a threat through firewalls and such. The flat model has only the gadgets/equipment in use to blame for anything that happens during the information migration.
According to analysts, the above is a better security measure because it does not arbitrarily block content like tiered end points often do. A firewall may restrict data even when it reveals the faintest signs of a bug in it but the flat network relies on the comparatively advanced detection system in place. Furthermore, since the advent of the access-core model, many capable entrepreneurs have displaced old-time providers who manipulated the end points with outdated machines. Servers, nowadays, from independent layers are more advanced and thus higher in protection.
The other pro about the flat model is that it consists of software that can overcome restrictions, automatically, to gain access to another point. This eliminates the need of multiple middlemen, each with a private firewall, like the hierarchal systems have. The security blessing here is that when middlemen reduce, security issues go down.
For the cloud to operate efficiently, it must have a dynamic architecture. These are nodes that intertwine, each feeding the other with information across various data networks. One of the chief advantages of the architecture of the flat model is that it is linear. There are no more clash points that are apparent in multi-tier networks, nor are there slow human middlemen to direct data traffic.
The security implication of this architecture is that it eliminates the delays that can help hackers to study a layer and make a move, in transit, before one retrieves data. This might appear a very theoretical assumption but the fact that machines have split-second detection capabilities to give or not give access to networks nullifies any doubts. There is no need to transfer from one node to another to find a safe entry point to a database, through trial and error. In the flat model, one is switched automatically to the safest node to a database available. If none is secure, the device itself, on either the core or access point, automatically denies entry.
So, is it secure after all?
It is hardly possible that the flat model is an entirely secure platform for cloud computing especially considering that it relies on the advanced technology of servers and devices to respond to security concerns. If outdated machinery is in use, then there is nothing networks can do than employ the good old firewalls. They have to deal with single websites depending on whether they want one to access them or not.
The IP addresses available for running access-to-core flat cloud networks are also limiting. Recent years have seen so many independent networks grab the opportunity to use this free model that congestion is setting in. This might be a future concern of safe data distribution.
In summary, one can say that cloud computing is in the hands of different networks. The flat model appears to be the nearest thing to achieving fast data exchanges, besides offering comparatively better security than the other options. However, the security is not sufficient and network providers will need to gang up to improve on it.
