This post will show you how to implement policy changes and staging with regards to auditing using Dynamic Access Control (DAC). This allows us to stage and test a central access policy before actually using it in production. This is a useful feature, as implementing DAC can be complex to work with.
If you’ve accidentally deleted a file in Linux, don’t worry, you can probably still restore it as long as that area of disk has not yet been overwritten. This post will show you how to easily restore a deleted file in Linux.
Foremost is able to search a disk or raw image file to recover files based on their headers, footers, and internal data structures.
The Server Message Block (SMB) protocol is used to provide file and print sharing in a Microsoft based network. To help detect man in the middle (MITM) attacks that may modify SMB traffic in transit, we can configure SMB signing via group policy. By digitally signing SMB packets the client and server can confirm where they originated from as well as their authenticity.
SMB packet signing is available in all supported versions of Windows. Microsoft also note that depending on factors such as the SMB version, file sizes, and specific hardware in use, SMB packet signing can degrade the performance of SMB, which is to be expected as we’re signing every packet that goes across the network, which adds overhead.
By default a full installation of Debian 9 Linux will have the graphical user interface (GUI) installed and it will load up after system boot, however if we have installed Debian without the GUI we can always install it later, or otherwise change it to one that is preferred.
This quick guide will cover how to install LXDE on Debian 9 Stretch, which will provide a GUI for working with the Linux system. While I don’t suggest using a GUI on a production server, it’s a good option if you’re using Debian as a desktop.
