Many telecommunications companies are now offering cloud services to their customers, including operators, businesses, and consumers. Storing files and applications in the cloud carries a number of potential benefits, but one concern that has arisen is the issue of security. Unlike closed local systems, where the perimeters can be secured, cloud computing is constantly shifting and changing. As a result, security approaches need to be tweaked in order to protect data. Here are a few of the main challenges facing the Telco Cloud, and how they can be overcome to provide a higher level of data security.
Securing multiple entry points
One of the biggest issues facing cloud security today is the fact that a cloud environment can be accessed through multiple entry points. Whether it’s a customer accessing your network through their own unsecured device, a web application accessing it with a virus, or a password leak, there are multiple ways that data could potentially be breached. The nature of the cloud means that it is meant to be accessed from anyplace at any time, so security officers need to work on bolstering this infrastructure and keeping a close eye on all of the potential points of access. Suppliers, contractors, customers, and employees alike may all access the same corporate application using mobile devices via the cloud. Unlike a traditional system where the perimeter can be secured with firewalls and virus detection systems, the cloud is more complicated.
Constant telco cloud upgrades are needed
Telco companies have worked hard to secure data breaches and create a safe environment for customers and operators alike, but with the move to a virtualised environment in the cloud new upgrades are needed. Telco cloud operators like Nokia Networks are working on finding new ways to upgrade their systems in order to meet these new challenges, and with the liquid nature of the cloud it’s necessary to be continually tweaking these upgrades to stay current with the latest needs. This requires a more organic, mobile approach to security than what you would traditionally use.
Scaling user access
With so many different entities accessing the cloud, another security challenge to think about is how to scale access. In other words, how can you be sure that the right user is accessing the right information in this shiftless format? Security teams can do this in various ways – they can subject privileged users to more scrutiny, while providing training to anyone in the corporation with direct access to the cloud. Access to data can also be limited depending on the type of device that a user has, and where they are using it. If a database administrator is in a public coffee shop, he may not be granted the same access to the data that he would within the main office building, for example.
These are just a few potential problems and solutions to think about when looking at the security of cloud computing systems. As telco companies make a move towards an increasingly virtualized environment, it’s important to find new ways to grow and change with this format to keep data safe from breaches. Advanced analytic’s and evolving perimeters are the best ways to do this.
