Learn how to secure your system and implement QoS using real-world scenarios for networks of all sizes using this unique book. The book covers:
Implementing Packet filtering, NAT, bandwidth shaping, packet prioritization using netfilter/iptables, iproute2, Class Based Queuing (CBQ) and Hierarchical Token Bucket (HTB)
Designing and implementing 5 real-world firewalls and QoS scenarios ranging from small SOHO offices to a large Learn how to secure your system and implement QoS using real-world scenarios for networks of all sizes using this unique book. The book covers:
Implementing Packet filtering, NAT, bandwidth shaping, packet prioritization using netfilter/iptables, iproute2, Class Based Queuing (CBQ) and Hierarchical Token Bucket (HTB)
Designing and implementing 5 real-world firewalls and QoS scenarios ranging from small SOHO offices to a large scale ISP network that spans many cities
Building intelligent networks by marking, queuing, and prioritizing different types of traffic
This practical guide teaches you how to implement effective network protection by using your own customized firewall solution. Based on extensive practical experience, this book distills a unique set of scenario based scripts and guidelines for a proven firewall solution, into one succinct and precise book.
After giving us a background of network security, the book moves on to explain the basic technologies we will work with, namely netfilter, iproute2, NAT and l7-filter. These form the crux of building Linux firewalls and QOS. The later part of the book covers 5 real-world networks for which we design the security policies, build the firewall, setup the script, and verify our installation.Providing only necessary theoretical background, the book takes a practical approach, presenting case studies and plenty of illustrative examples.
