New security tools help to seal the cloud – Sprocket Networks

Computing is now cloud based! Cloud computing is basically the delivery of storage and computing ability or capacity to a group of end-users.  However, with this kind of arrangement there come a lot of risks to the data that is transferred amongst the various points. Since there is risk of data manipulation, vandalizing and even theft, there is need of setting up of functional and effective data security centers. Such data security centers need to take up the latest and most advanced security tools to help seal the gaps that may exist in the cloud.

However, it is not all data security tools that work well with the cloud computing providers. Some vendors have taken up the responsibility to come up with their own security tools to curb the insecurity experienced in cloud computing. There are even some vendors that don’t allow you as the user to manage your cloud whether internal or external as a single unit. Such vendors don’t let you allocate additional security systems under the operating system. Here you will have to trust your cloud vendor’s security level. You may also choose to stick with a private cloud within your own firewall or you can even create an external environment using your own network at an external site hence keeping storage under your control.

A public cloud will require your attention pertaining to components like the load balancers, network firewall and network address translation that will hide the public internet protocol address that your provider will assign your server. It does not matter the model you choose, whether Software as a Services (SaaS), Infrastructure as a Service(IaaS) or Platform as a Service(PaaS), the automatic and consistent processes needed for cloud deployment improve security as well as increase reliability, efficiency and performance.

The use of data security tools to help tackle threats on data at the various data security centers are categorized according to the level of security. These categories include SOA, XML and Application Security. There are also categories like encryption tool for data whether in transit or at rest, smart key management, identity and access management, log management and virtual firewalls as well as other virtualization tools, data loss prevention. This is basically introducing available security structures into the cloud hence various tools will be needed depending on the cloud layers. However, some tools already exist.

In the SaaS layer, all applications by the provider usually run on cloud infrastructure and are entirely accessed over a web browser. In this case you will not be able to manage the servers, networks, operating systems, individual applications and storage. It is therefore up to the vendor to secure the platform.

The PaaS Layer on the other hand allows you to create application using the many programming languages and tools offered by the vendor. You can then deploy these applications into the cloud infrastructure. Here, security issues involving the management APIs like authorization, auditing and authentication should be put into consideration by the user.

With IaaS you will have fewer options when it comes to security capability integration beyond infrastructure protection. However, there is a lot of extensibility. This means that it is up to the user to ensure that they manage and secure all operating systems, content and applications usually through API.
