New security risks, continuously evolving regulation and increasing security standards have created new and growing needs for secure internal information transfers, which SSH provides. This book addresses these new trends in depth, offering the most up-to-date information on the integration of SSH into a security environment. It covers the newest features and applications of SSH-2 (which received Proposed Standard status from the IETF in 2006). SSH2 is more secure than previous versions and has many expanded uses on a wider variety of computing platforms. Another particular note driving new SSH2 adoption are the requirements of recent legislation (PCI/HIPAA/SOX/FISMA). SSH 2 has become an even more valuable tool, as it provides communications security compliance with the latest standards.This book offers the most up-to-date information on SSH2 in a practical, hands-on, tutorial-style reference that goes well beyond UNIX implementation. It concentrates on the latest version of SSH 2 with all new information. - Discover why SSH2 offers more robust security than SSH1 and how to incorporate it into your network administration software toolbox

Linux servers now account for 33% of all networks servers running worldwide (Source: IDC). The top 3 market share holders in the network server space (IBM, Hewlett-Packard, and Dell) all use Linux as their standard operating system. This book teaches Linux system administrators how to protect their servers from malicious threats.As with any technologies, increased usage results in increased attention from malicious hackers. For years a myth existed that Windows was inherently less secure than Linux, because there were significantly more attacks against Windows machines than Linux. This was a fallacy. There were more attacks against Windows machines because there were simply so many more Windows machines to attack. Now, the numbers tell the exact opposite story. Linux servers account for 1/3 of all servers worldwide, but in 2005 there were 3 times as many high-severity security vulnerabilities discovered on Linux servers (Source: IDC).This book covers Open Source security, implementing an intrusion detection system, unearthing Rootkits, defending against malware, creating Virtual Private Networks, and much more.The Perfect Reference for the Multitasked SysAdmin* Discover Why "Measure Twice, Cut Once" Applies to Securing Linux* Complete Coverage of Hardening the Operating System, Implementing an Intrusion Detection System, and Defending Databases* Short on Theory, History, and Technical Data that Is Not Helpful in Performing Your Job

If you think Knoppix is just a Linux demo disk, think again. Klaus Knopper created an entire Linux distribution on a bootable CD (and now a DVD) so he could use his favorite open source tools on any computer.

Written by hackers for hackers, this hands-on book teaches penetration testers how to identify vulnerabilities in apps that use GraphQL, a data query and manipulation language for APIs adopted by major companies like Facebook and GitHub. Black Hat GraphQL is for anyone interested in learning how to break and protect GraphQL APIs with the aid of offensive security testing. Whether you’re a penetration tester, security analyst, or software engineer, you’ll learn how to attack GraphQL APIs, develop hardening procedures, build automated security testing into your development pipeline, and validate controls, all with no prior exposure to GraphQL required. Following an introduction to core concepts, you’ll build your lab, explore the difference between GraphQL and REST APIs, run your first query, and learn how to create custom queries. You’ll also learn how to: Use data collection and target mapping to learn about targets Defend APIs against denial-of-service attacks and exploit insecure configurations in GraphQL servers to gather information on hardened targets Impersonate users and take admin-level actions on a remote server Uncover injection-based vulnerabilities in servers, databases, and client browsers Exploit cross-site and server-side request forgery vulnerabilities, as well as cross-site WebSocket hijacking, to force a server to request sensitive information on your behalf Dissect vulnerability disclosure reports and review exploit code to reveal how vulnerabilities have impacted large companies This comprehensive resource provides everything you need to defend GraphQL APIs and build secure applications. Think of it as your umbrella in a lightning storm.
