Securing Hadoop networks
There are multiple steps in securing Hadoop networks. The first step in designing the Hadoop cluster is to set up the network. In the next subsections, we will talk about different types of networks, network firewall usage and different tools available in the market to secure the network.
Segregating different types of networks
Segregating or segmenting your enterprise network is one of the most basic aspects of securing your Hadoop network. In general, segmentation is one of the practices followed by enterprises. However, when you are setting up a Hadoop cluster you need to ensure that certain aspects are in your network design.
You should think about the following aspects one by one:
- What kind of traffic would there be? Are we getting any traffic from the internet or will it all be internal network traffic?
- Do we have inbound or outbound traffic over internet or intranet? What services would have inbound or outbound traffic, or both?
