Implement Industrial-Strength Security on Any Linux Server

 

In an age of mass surveillance, when advanced cyberwarfare weapons rapidly migrate into every hacker’s toolkit, you can’t rely on outdated security methods–especially if you’re responsible for Internet-facing services. In Linux® Hardening in Hostile Networks, Kyle Rankin helps you to implement modern safeguards that provide maximum impact with minimum effort and to strip away old techniques that are no longer worth your time.

 

Rankin provides clear, concise guidance on modern workstation, server, and network hardening, and explains how to harden specific services, such as web servers, email, DNS, and databases. Along the way, he demystifies technologies once viewed as too complex or mysterious but now essential to mainstream Linux security. He also includes a full chapter on effective incident response that both DevOps and SecOps can use to write their own incident response plan.

 

Each chapter begins with techniques any sysadmin can use quickly to protect against entry-level hackers and presents intermediate and advanced techniques to safeguard against sophisticated and knowledgeable attackers, perhaps even state actors. Throughout, you learn what each technique does, how it works, what it does and doesn’t protect against, and whether it would be useful in your environment.

  • Apply core security techniques including 2FA and strong passwords
  • Protect admin workstations via lock screens, disk encryption, BIOS passwords, and other methods
  • Use the security-focused Tails distribution as a quick path to a hardened workstation
  • Compartmentalize workstation tasks into VMs with varying levels of trust
  • Harden servers with SSH, use apparmor and sudo to limit the damage attackers can do, and set up remote syslog servers to track their actions
  • Establish secure VPNs with OpenVPN, and leverage SSH to tunnel traffic when VPNs can’t be used
  • Configure a software load balancer to terminate SSL/TLS connections and initiate new ones downstream
  • Set up standalone Tor services and hidden Tor services and relays
  • Secure Apache and Nginx web servers, and take full advantage of HTTPS
  • Perform advanced web server hardening with HTTPS forward secrecy and ModSecurity web application firewalls
  • Strengthen email security with SMTP relay authentication, SMTPS, SPF records, DKIM, and DMARC
  • Harden DNS servers, deter their use in DDoS attacks, and fully implement DNSSEC
  • Systematically protect databases via network access control, TLS traffic encryption, and encrypted data storage
  • Respond to a compromised server, collect evidence, and prevent future attacks

Author: Rob Flickenger
Brand: Brand: O'Reilly Media

A competent system administrator knows that a Linux server is a high performance system for routing large amounts of information through a network connection. Setting up and maintaining a Linux server requires understanding not only the hardware, but the ins and outs of the Linux operating system along with its supporting cast of utilities as well as layers of applications software. There's basic documentation online but there's a lot beyond the basics you have to know, and this only comes from people with hands-on, real-world experience. This kind of "know how" is what we sought to capture in Linux Server Hacks.Linux Server Hacks is a collection of 100 industrial-strength hacks, providing tips and tools that solve practical problems for Linux system administrators. Every hack can be read in just a few minutes but will save hours of searching for the right answer. Some of the hacks are subtle, many of them are non-obvious, and all of them demonstrate the power and flexibility of a Linux system. You'll find hacks devoted to tuning the Linux kernel to make your system run more efficiently, as well as using CVS or RCS to track the revision to system files. You'll learn alternative ways to do backups, how to use system monitoring tools to track system performance and a variety of secure networking solutions. Linux Server Hacks also helps you manage large-scale Web installations running Apache, MySQL, and other open source tools that are typically part of a Linux system.O'Reilly's new Hacks Series proudly reclaims the term "hacking" for the good guys. Hackers use their ingenuity to solve interesting problems. Rob Flickenger is an experienced system administrator, having managed the systems for O'Reilly Network for several years. (He's also into community wireless networking and he's written a book on that subject for O'Reilly.) Rob has also collected the best ideas and tools from a number of other highly skilled contributors.Written for users who already understand the basics, Linux Server Hacks is built upon the expertise of people who really know what they're doing.
