The authentication server authenticates each client connected to a switch port and assigns the port to a VLAN before making available any services offered by the switch or the LAN. Until the client is authenticated, 802.1X access control allows only Extensible Authentication Protocol over LAN (EAPOL) traffic through the port to which the client is connected. After authentication is successful, normal traffic can pass through the port.

ARP inspection provides a mapping between a default gateway IP address and its MAC address. If the switch sees a gratuitous ARP carrying an invalid mapping, the switch drops the packet, thereby preventing ARP spoofing attacks. SYN/ACK response (the second part of the TCP three—way handshake) is still sent, but with no connection — state information kept. If the final ACK for the three—way handshake is received, the server recalculates the original information that had come with the initial SYN.

OS vulnerabilities are continually being published. Sophisticated attack tools are publicly available and become more and more user—friendly. This means that anybody with Internet access can find a wide variety of tools and vulnerabilities to exploit. In the 2002 CSI/FBI security survey, respondents noted that approximately 40 to 45 percent of all attacks on their systems occurred from sources residing on the internal network. The increasing need to protect internal devices and applications from attacks and unauthorized access attempts is directly reflected in these survey results. Data centers should be designed to protect against attacks carried out by external client machines (on the Internet), internal client machines, and compromised servers.

PVLANs provide isolation of ports from one another within the same VLAN. With private VLANs you can use a single subnet and force all the server—generated traffic to go to a promiscuous or upstream port, which typically is a router port, or a VLAN interface on a FWSM. By doing so, servers can be protected from Layer—2 attacks such as ARP spoofing, even where other devices in the same VLAN may be compromised. Use switches that support hardware—based PVLAN segregation. The IEEE 802.1X standard defines a client—server—based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports.

Enterprise networks continue to increase in complexity, and threats to networks are more severe than ever. Protecting these environments takes more than great technology, it takes effective and continuous management. Without the right systems in place, that can be a costly and time—consuming undertaking. IAM addresses the inherent complexity and changing requirements of today’s enterprise networks by providing continuous visibility into network security devices and policies across the enterprise. Enterprise—level dashboards provide at—a—glance analysis of rule usage, complexity and compliance.

Traffic flow analysis tracks traffic behavior across the network down to the application level. Access path analysis traces every available access path across the network and visualizes relationships between devices. Customizable controls and assessments to report on what’s important to you. Search and filtering for every device, rule and object on the network. Clean up — analyze firewall configurations to identify hidden, unused, shadowed or overly permissive rules. Compliance — validate policies against regulatory requirements, including PCI DSS 3.2, or against custom—defined policies.

Enterprises are rapidly enabling new technologies to meet business demands, but this also opens the door to new attacks. The risk is compounded by the ever—evolving threat landscape and today's complex, borderless networks. Cloud computing is becoming increasingly popular among enterprises looking to take advantage of the quick deployment, unprecedented scalability, and cost savings. Private cloud infrastructure, including virtualization and software defined networking, are rapidly transforming data centers. At the same time, organizations are rapidly embracing public clouds, both migrating workloads to Infrastructure—as—a—Service clouds like AWS and Azure, and adopting Software—as—a—Service applications.

This results in a hybrid cloud and increasingly multi—cloud environment that is borderless for your enterprise users, data, and applications. Evolving your infrastructure means your security must evolve as well, to protect your enterprise regardless of where your infrastructure and applications are running. If your security can’t keep up with the agile public, private, and hybrid cloud environments, gaps in protection will occur. There are a number of deployment methods being used that require scalable security capable of keeping up with elastic workloads. Fortinet provides comprehensive security for private, public, and hybrid deployments before, during, and after migration.
