Firewalls, VPNs, Bandwidth
Firewalls are among the best-known network security tools in use today, and their critical role in information security continues to grow. However, firewalls are most effective when backed by thoughtful security planning, well-designed security policies, and integrated support from anti-virus software, intrusion detection systems, and related tools. Coverage includes packet filtering, authentication, proxy servers, encryption, bastion hosts, virtual private networks (VPNs), log file maintenance, and intrusion detection systems. We offer an abundant selection of realistic projects and cases incorporating cutting-edge technology and current trends. This includes enhanced coverage of network security and VPNs, and information on relevant National Institute of Standards and Technology guidelines used by businesses.
