Network Security Hacks—100 Industrial-Strength Tips & Tools by Andrew Lockhart
With the ever-growing complexity of networks, administrators need an intricate array of tools and skills to ensure their network's security. Andrew Lockhart's practical Network Security Hacks—100 Industrial-Strength Tips & Tools provides an abundance of clever hacks to help fill your needs.
As with the other books in the series, this is a compilation of tips collected from real-world users who have faced the same problems that most of us deal with today.
The hacks range from automating simple system administration tasks, such as checking for patches that have been applied, to restricting permissions on filesystems that rarely change. Concepts are explained clearly, making them easy to understand, yet they still offer advice to seasoned professionals. I recommend Network Security Hacks for relatively inexperienced administrators as well as for experts.
This book dispels the myth that simply having a firewall is a complete security design. As a consultant for several large companies, I've seen how prevalent this idea really is. Instead, the book first approaches security by discussing how to harden your servers. Of course, it still offers tips on firewalls and packet filtering.
Unlike many others, Lockhart's book is comprehensive; covering tips for UNIX, Linux and Microsoft Windows systems. Because no system or network is impenetrable, meaning every system can be compromised, Lockhart offers a critical approach to minimizing the impact of a security breach. From hardening a server, applied encryption, trending and logging to intrusion detection and incident response, Andrew Lockhart's Network Security Hacks—100 Industrial-Strength Tips & Tools is an excellent resource.
Practical Task Scheduling Deployment

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.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
