Free download Free Sudo Mastery: User Access Control for Real People from with Mediafire Link Download LinkUnix-like operating systems have a primitive access control system. The root account can do anything. Other users are peasants with only minimal system access. This worked fine in UNIX’s youth, but today, system administration responsibilities are spread among many people and applications. Each person needs a tiny slice of root’s power.
Sudo lets you divide root’s monolithic power between the people who need it, with accountability and auditability.
Sudo Mastery will teach you to:
* design a sudo policy rather than slap rules together
* simplify policies with lists and aliases
* use non-Unix information sources in policies
* configure alternate sudo policies
* manage shell environments
* verify system integrity and perform intrusion detection
* have a common sudo policy across your server farm
* manage sudo policies via LDAP
* log and debug sudo
* log and replay full sudo sessions
* use authentication systems other than passwords
While many people use sudo, most use only a small part of it’s features. Chances are, you’re doing it wrong. Master sudo with Sudo Mastery.Books with free ebook downloads available Free Sudo Mastery: User Access Control for Real People [Kindle Edition]

Free Sudo Mastery: User Access Control for Real People
Michael W Lucas has always been one of my favorite authors because he brings exceptional narrative to information that has the potential to be rather boring. Sudo Mastery is no exception.
I should begin by saying that I'm not a sysadmin. I work in information security and spend most of my time breaking into systems or trying to catch people who breaking into systems. Because of this, I focused on the components of the book that I thought were the most relevant to me. Particularly, ways that I could use sudo in post-exploitation scenarios or ways to interpret sudo commands in incident response scenarios. I was very pleased with the content, and feel like my day to day job benefits from having the knowledge gained from it.
Overall, I didn't know that there was so much to learn related to sudo. This book will stay on my iPad as my definitive sudo resource any time I need to dig back into the advanced mechanics of the tool. I can only imagine that sysadmins who use sudo from an administrative level will find this book monumentally useful. The book is a quick read, full of useful information, and well put together. It's a very focused book for a very focused tool, and does a perfect job at delivering on all counts.

If you're a sysadmin, your expertise might be limited -- as mine was -- to something like "%wheel ALL=(ALL) ALL", then making sure you're in the wheel group. But sudo can do more, so very much more. Did you know that sudo -i can replace "sudo su -"? I didn't. How about sudoreplay, which lets you see exactly what someone did to bring down the system? News to me. Michael W. Lucas takes us through sudo from start to finish, from local files to LDAP, from let-the-sysadmin-do-anything to precisely delimited DBA-appropriate commands, and explains the wherefores, the whys and the WTFs along the way. He's careful, he's precise, and he lets you know the shortcomings that inevitably accompany any problem's solution.
Lucas' writing is great, as always. I've read many of his books, and I enjoy the way he will step back and bring some levity. If that's not your cup of tea, I suppose you could pass this up...but man, you'd be missing out.
It's awesome, it's Lucas, it's sudo. Buy it now.
