CHAPTER 8 | Services DoS DOS Denial of Service (DoS) is an attempt by a hacker to flood an IP address, domain, or server with repeated external communincation requests, effectively saturating the system with an information flood that renders it slow or effectively inoperable for genuine users to access it. DoS attacks are also referred to as non-intrusion attacks, the goal of which is to cripple your system but not steal data.
CHAPTER 8 | Services DoS ■ Whole System Flood: FIN: Prevents a FIN (no more data from sender) flood in which part of a TCP packet from an invalid (or spoofed) IP address floods the network with connection resets. ■ Whole System Flood: UDP: Prevents a flood of large numbers of raw UDP (User Datagram Protocol) packets targeted at the unit. ■ Whole System Flood: ICMP: Prevents a flood of ICMP (internet control message protocol) messages from an invalid IP address causing all TCP requests to be halted.
CHAPTER 8 | Services IGMP Proxy Configuration ■ TCP SynWithData: Prevents the hacker sending a volume of requests for connections that cannot be completed. ■ UDP Bomb: Also called a UDP Flood or packet storm. Prevents the hacker congesting the network by generating a flood of UDP packets between it and the unit using the UDP chargen service (a testing utility that generates a character string for every packet it receives).
CHAPTER 8 | Services IGMP Proxy Configuration Figure 63: IGMP Proxy Configuration The following items are displayed on this pages: ◆ IGMP Proxy — Enables IGMP proxy.
CHAPTER 8 | Services RIP Configuration RIP CONFIGURATION RIP is an Internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP’s location, or on remote networks connected to your network via the ADSL line. Most small home or office networks do not need to use RIP; they have only one router, such as the router, and one path to an ISP.
CHAPTER 8 | Services ARP Binding Configuration ARP BINDING CONFIGURATION The router uses its tables to make routing decisions, and uses Address Resolution Protocol (ARP) to forward traffic from one hop to the next. ARP is used to map an IP address to a physical layer MAC address. When an IP frame is received by the router, it first looks up the MAC address corresponding to the destination IP address in the ARP cache.
