Learning DevSecOps
My latest book from O'Reilly Media covers building security into every phase of the software development lifecycle. It addresses the cultural, process, and technical changes needed to make security a shared responsibility across development, operations, and security teams.
Asterisk
A minor code contribution to the open source PBX surrounding distinctive ring detection and the options for configuration thereof.
sysfs.pl
An admittedly ugly script to get information from the /sys filesystem on Linux about SCSI disks. Particularly helpful for obtaining the raw size of SCSI disks, LUNs (in hex), and other such bits produced by the /sys filesystem.
Syncdir
A directory synchronization script. Lighter than a full rsync wrapper, it copies into a directory instead of directly on another partition.
