More importantly, it gives you a comprehensive understanding of the threats to your organization's network and teaches you a systematic approach in which you make optimal use of the technologies available to you. Coverage includes: Understanding security from a topological perspective Configuring Cisco router security features Selecting and configuring a firewall Configuring Cisco's PIX firewall Configuring an intrusion detection system Providing data redundancy Configuring a Virtual Private Network Securing your wireless network Implementing authentication and encryption solutions Recognizing hacker attacks Detecting and eradicating viruses Getting up-to-date security information Locking down Windows NT/2000/XP servers Securing UNIX, Linux, and FreBSD systems

Organizations of all sizes struggle to secure their data in a constantly evolving digital landscape. Expanding digital footprints and the rapid expansion of cloud strategies arising from the COVID-19 pandemic increase an organization’s attack surface. When combined with limited resources caused by the cybersecurity skills gap, securing small and mid-sized business IT infrastructures becomes more complicated. With limited staffing and budgetary restrictions, small businesses need to create cost-effective, security-driven programs that protect data while also meeting increasingly stringent compliance requirements. This book bridges the gap between complex technical language and business objectives to create a security-first review of the security and compliance landscapes. Starting from the premise that “with security comes compliance,” this book starts by defining “security-first” and then walking readers through the process of creating a holistic security and compliance program. Looking at security and privacy through the lens of zero trust, this overview of regulations and industry standards provides both background about and implications drawn from modern security practices. Rather than focusing solely on individual cybersecurity frameworks, this book offers insights into best practices based on the commonalities between regulations and industry standards, highlighting some of the primary differences to show the nuances. Woven throughout are practical examples of solutions that enable small and mid-sized businesses to create “cybersustainable” security-focused policies, processes, and controls that protect today’s future for tomorrow’s digital ecosystem.
