Linux Means Business: Security and Authentication with Digital Signatures
This scheme reduces the security requirements in the labs, but increases the precautions that need to be taken in the Field Staff's offices. Their PCs will have the secret keys on them, and plans should be made for when a computer is “compromised”. A possible fix is to give each education center a separate key set and put all possible public keys on the servers. If a system/key/passphrase is stolen, that particular key set is revoked and not used any more.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.
