Both the FMC and FTD are deployed as virtual machines. The ISR connects to the UCSE Series blades through two internal interfaces. The ISRG2 Slot. is the PeripheralComponentInterconnectExpress (PCIe) internal interface, and the UCSE Series blade Slotl is the switching interface to the backplane Multi Gigabit Fabric (MGF). The Cisco ISR 4000 Series routers have two internalinterfaces are connected to the MGF. The UCSE Series blades have a hypervisor (hypervisor) installed, and Cisco FTD software runs on them as a virtual machine. The ISR platforms that support FTR are shown below.CiscoISRG2 Series: 2911, 2921, 2951, 3925, 3945, 3925E, and 3945E.CiscoISR4000 Series: 4331, 4351, 4451, 4321, and 443lo128 Chapter 2 Network Security Appliances and Cloud Services2.2.6 Personal firewallsA personal firewall is a common software application that can be installed on an end-user computer or server to address and block security threats and intrusions from outside. The term "personal firewall" refers to basic protection software installed on a personal computer that controls access to the personal computer from the third and fourth layers. Today, smarter software not only supports basic personal firewall functionality, but can also protect the operating system based on the way the installed applications operate.2.2.7 Intrusion Detection Systems and Intrusion Prevention SystemsAn intrusion detection system (IDS) is a detection device (deployed in promiscuous mode) that detects a variety of attack attempts by out attackers, including illegal access to a network or host, malicious depletion of system performance, and theft of information. IDS can also detect distributed denial-of-service (DDoS) attacks, worms, and so on. Figure 2.12 shows how an IDS appliance deployed in promiscuous mode can detect security threats.
