Abstract: Various of the disclosed embodiments contemplate systems and methods for implementing network security without extensive remodeling of the network infrastructure. Rather than redesign a network topology to accommodate a plurality of firewall devices at the network periphery, various embodiments introduce localized access proxy systems, e.g., into an existing legacy network. Rule sets operating at the local proxies may ensure compliance with various security standards (e.g., PCI-DSS) without requiring an extensive overhaul of the network's connections.
