Secure your systems against today's attacks—and tomorrow's.
Halting the Hacker: A Practical Guide to Computer Security, Second Edition combines unique insight into the mind of the hacker with practical, step-by-step countermeasures for protecting any HP-UX, Linux, or UNIX system.
Top Hewlett-Packard security architect Donald L. Pipkin has updated this global bestseller for today's most critical threats, tools, and responses. Pipkin organizes this book around the processes hackers use to gain access, privileges, and control—showing you exactly how they work and the best ways to respond. Best of all, Pipkin doesn't just tell you what to do, but why. Using dozens of new examples, he gives you the skills and mindset to protect yourself against any current exploit—and attacks that haven't even been imagined yet.
- How hackers select targets, identify systems, gather information, gain access, acquire privileges, and avoid detection
- How multiple subsystems can be used in harmony to attack your computers and networks
- Specific steps you can take immediately to improve the security of any HP-UX, Linux, or UNIX system
- How to build a secure UNIX system from scratch—with specifics for HP-UX and Red Hat Linux
- Systematic proactive, reactive, and preemptive security measures
- Security testing, ongoing monitoring, incident response, and recovery—in depth
- Legal recourse: What laws are being broken, what you need to prosecute, and how to overcome the obstacles to successful prosecution
The accompanying CD-ROM contains an extensive library of HP-UX and Linux software tools for detecting and eliminating security problems and a comprehensive information archive on security-related topics.
