5) How do I monitor and audit Hadoop security after it goes-live?
Auditing the Hadoop platform is the final key piece of an effective and secure data practice. Auditing allows planners to know how users have been using the platform and address any anomalies that may be suspicious. Tools that inspect the Hadoop logs and enable predictive tracking can help them detect bad behaviors and target them before they become a bigger threat.
Simply running a data audit and indexing data can help identify new data and security permissions and policies that need to be applied. It is about gaining that visibility into data usage and the routes taken. Public sector teams need this visibility to know where the data is coming from, and how it is being used all the time without exceptions.
Safeguarding data in a smart city
The current data explosion will continue and public sector organizations will have to manage more and more data. This is especially so in a smart city environment where citizens and the government are more connected than ever before, and where data powers everything from the public transport system to the water and waste management system.
A Hadoop based EDH, offering flexibility, scalability and security, allows public sector organisations to be future ready today. IT leaders in the public sector need to know that it is possible to ensure compliance and security in Hadoop. Moreover, the continued innovation in the platform will also allow public sector organisations to strengthen that security over time.
