Comments: 3 Creating Encrypted FTP Backups With duplicity And duply On Debian Squeeze When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and duply to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. duply is a duplicity wrapper script that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04
Author: nowen •
Tags: apache, debian, security, ubuntu •
Comments: 0 How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04 This document describes how to add WiKID two-factor authentication to Apache 2.2.22 using mod_auth_radius on Ubuntu 12.04. It is also recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.

Tags: debian, security, storage, ubuntu •
Comments: 2 Encrypt Your Data With EncFS (Debian Squeeze/Ubuntu 11.10) EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Debian Squeeze/Ubuntu 11.10 to encrypt your data.
