Compared to SMB, NFS over stunnel offers better encryption (likely AES-GCM if used with a modern OpenSSL) on a wider array of OS versions, with no pressure in the protocol to purchase paid updates or newer OS releases. NFS is hardly alone in this shortcoming, as I have already covered clear-text SMB in a previous article. Absent Kerberos, the protocol operates only in clear text, and this presents an unacceptable security risk in modern settings. Let’s go through the process step by step: Choose AMI select Ubuntu Server 20.04 LTS (HVM) Choose Instance Type select t2.micro (probably t2.nano would be also sufficient) Configure Instance leave everything as is. However, this requires sharing PID namespace so that the watch dog can kill the stunnel. This approach leverages kubelet being the init system, so that the container will be restarted once crashes. The most obvious feature missing from NFSv4 is native, standalone encryption. In order to create an instance, go to the EC2 service and click the Launch instance button. Create a new container, efs-watch-dog, in the efs node daemonset pod.

Decades old and predating Linux, the most modern v4 releases are easily firewalled and offer nearly everything required for seamless manipulation of remote files as if they were local. The Network File System (NFS) is the most popular file-sharing protocol in UNIX. Before you use your cloud provider’s NFS tools, review all of your NFS usage and secure it where necessary. In order to maximize file system availability in the event that the CA is not reachable from your VPC, the Online Certificate Status Protocol (OCSP) is not enabled by default when you choose to encrypt data in transit. Enabling Online Certificate Status Protocol. Let’s go through the process step by step: Choose AMI select Ubuntu Server 20. TLS can wrap this traffic, finally bringing protocol security. For more information on using encryption of data in transit, see Mounting EFS file systems. In order to create an instance, go to the EC2 service and click the Launch instance button. NFS clients and servers push file traffic over clear-text connections in the default configuration, which is incompatible with sensitive data.
