Firewall

A firewall protects networked computers from intentional hostile intrusion that could compromise

confidentiality or result in data corruption or denial of service. It must have at least two network

interfaces, one for the network it is intended to protect,

firewall sits at the junction point or gateway between the two networks, usually a private network

and a public network such as the Internet.

A firewall examines all traffic routed between the two networks to

does, it is routed between the networks, otherwise it is stopped. A firewall filters both inbound and

outbound traffic. It can also manage public access to private networked resources such as host

applications. It ca

n be used to log all attempts to enter the private network and trigger alarms when

hostile or unauthorized entry is attempted. Firewalls can filter packets based on their source and

destination addresses and port numbers. This is known as address filtering

filter specific types of network traffic. This is also known as protocol filtering because the decision

to forward or reject traffic is

Firewalls can also filter traffi

c by packet attribute or state.

An Internet firewall cannot prevent individual users with modems from

network. By doing so they bypass the firewall altogether. Employee misconduct or carelessness

cannot be controlled by firewall

accounts must be strictly enforced. These are management issues that should be raised during

the planning of any security policy, but that cannot be solved with Internet firewalls alone.

Types of Firewall

There are three types of firewall:

Packet Filtering

In packet filtering, only the protocol and the address information of each packet is examined. Its

contents and context (its relation to other packets and to the intended application) are

The firewall pays no attention to applications on the host or local network and it "knows" nothing

about the sources of incoming data. Filtering consists of examining incoming or outgoing packets

and allowing or disallowing their transmission or a

rules. Network Address Translation (NAT) routers offer the advantages of packet filtering firewalls

but can also hide the IP addresses of computers behind the firewall, and offer a level of

circuit-based filtering.

Circuit Gateway

Also called a "Circuit Level Gateway," this is a firewall approach that validates connections before

allowing data to be exchanged. What this means is that the firewall doesn't simply allow or

disallow packets but also determines wh

according to configurable rules, then opens a session and permits traffic only from the allowed

source and possibly only for a limited period of time.

Application Gateway

The Application Level Gateway acts

with the remote system in their behalf. This can render a computer behind the firewall all but

invisible to the remote system. It can allow or disallow traffic according to very specific rules, for

instance permitting some commands to a server but not others, limiting file access to certain types,

varying rules according to authenticated users and so forth. This type of firewall may also perform

very detailed logging of traffic and monitoring of eve

instructed to sound alarms or notify an operator under defined conditions. Application

gateways are generally regarded as the most secure type of firewall. They certainly have the most

sophisticated capabilities.

Denial of Service

Attack

Denial of service (DoS) attacks typically come in two flavors: resource starvation and resource

overload. DoS attacks can occur when there is a legitimate demand for a resource that is greater

than the supply (i.e. too many w

vulnerabilities or system mis

configurations

a malicious denial of service and simple system overload is the requirement of an individual with

m

alicious intent (attacker) using or attempting to use resources specifically to deny those

resources to other users.

Ping of death-

On the Internet, ping of death is a kind of denial of service (DoS) attack caused by

an attacker deliberately sending an IP packet larger than the 65,536 bytes allowed by the IP

protocol. One of the features of TCP/IP is fragmentation; it allows a single

down into smaller segments. Attackers began to take advantage of that feature when they found

that a packet broken down into fragments could add up to more than the allowed 65,536 bytes.

Many operating systems didn't know what to do

froze, crashed, or rebooted. Other known variants of the ping of death include teardrop, bonk and

nestea.

SYN Flood-

The attacker sends TCP SYN packet which start connections very fast, leaving the

victim wa

iting to complete a huge number of connections, causing it to run out of resources and

dropping legitimate connections. A new defense against this is the “SYN cookies”. Each side of a

connection has its own sequence number. In response to a SYN, the attack

special sequence number that is a “cookie” of the connection then forgets everything it knows

about the connection. It can then recreate the forgotten information about the connection where

the next packets come in from a legitimate co

ICMP Flood-

The attacker transmits a volume of ICMP request packets to cause all CPU

resources to be consumed serving the phony requests.

UDP Flood-

The attacker transmits a volume of requests for UDP diagnostic services which cause

all CPU re

sources to be consumed serving the phony requests.

Land attack-

The attacker attempts to slow your network down by sending a packet with identical

source and destination addresses originating from your network.

Smurf attack-

Where the source address of a broadcast ping is forged so that a huge number of

machines respond back to victim indicated by the address, overloading it.

Fraggle Attack-

A perpetrator sends a large amount of UDP echo packets at IP broadcast

addresses, al

l of it having a spoofed source address of a victim.

IP Spoofing-

IP Spoofing is a method of masking the identity of an intrusion by making it appeared

that the traffic came from a different computer. This is used by intruders to keep their anonymity

can be used in a Denial of Service attack.

VLAN (Virtual Local Area Network)

Virtual LAN (VLAN) is defined as a group of devices on one or more LANs that are configured so

that they can communicate as if they were attached to the same wire, when in fact

on a number of different LAN segments. Because VLAN is based on logical instead of physical

connections, it is extremely flexible.

The IEEE 802.1Q defines the operation of VLAN bridges that permit the definition, operation, and

administra

tion of VLAN topologies within a bridged LAN infrastructure. VLAN architecture benefits

include:

•

Increased performance

•

Improved manageability

•

Network tuning and simplification of software configurations

•

Physical topology independence

• Increased security

We discuss the implementation of VLAN

Specification

•

The unit supports up to 8 active VLANs with shared VLAN learning (SVL) bridge out of

4096 possible

VLANs specified in IEEE 802.1Q.

•

Each port always belongs to a default VLAN with its port VID (PVID) as an untagged

member. Also, a port can belong to multiple VLANs and be tagged members of these

VLANs.

Configuration to the router

This guide is designed to lead users through Web Configuration of G.shdsl Router in the easiest

and quickest way possible. Please follow the

Note: There are three methods to configure the router: serial console, Telnet and Web Browser.

Only one configuration application is used to setup the Router at any given time. Users

have to choose one method to configure it.

For Web configuration, you can skip step

For Serial Console Configuration, you can skip step 1 and 3.

Step 1: Check the Ethernet Adapter in PC or NB

Make sure that

Ethernet Adapter had been installed in PC or NB used for configuration of the

router. TCP/IP protocol is necessary for web configuration, so please check the TCP/IP protocol

whether it has been installed.

Step 2: Check the Terminal Access Program

For

Serial Console and Telnet Configuration, users need to setup the terminal access program

with VT100 terminal emulation.

Step 3: Check the Web Browser in PC or NB

According to the Web Configuration, the PC or NB need to install Web Browser, IE or Netscap

Note: Suggest to use IE5.0, Netscape 6.0 or above and 800x600 resolutions or above.

Step 4: Determine Connection Setting

Users need to know the Internet Protocol supplied by your Service Provider and determine the

mode of setting.

RFC1483 RFC1577 RFC2364 RFC2516

The different protocols are needed to setup the difference WAN parameters. After

protocol provided by your ISP, you have to setup the right protocol.

Step 5: Install the SHDSL Router

To avoid possible damage to this Router, do not turn on the router before Hardware Installation.

•

Connect the power adapter to the port

•

Connect the Ethernet cable.

Note: If the

router is directly connected to PC or NB, the Ethernet cable has to be use

DHCP Server

Dynamic Host Configuration Protocol (DHCP) is a communication proto

administrators to manage centrally and automate the assignment of Internet Protocol (IP)

addresses in an organization's network. Using the Internet Protocol, each machine that can

connect to the Internet needs a unique IP address. Whe

users with a connection to the Internet, an IP address must be assigned to each machine

be connected.

Without DHCP, the IP address must be entered manually at each computer. If computers move to

another

location in another part of the network, a new IP address must be entered. DHCP lets a

network administrator to supervise and distribute IP addresses from a central point and

automatically sends a new IP address when a computer is plugged into a different

network. If the DHCP server is Enable, you have to setup the following parameters for processing

it as DHCP server.

The embedded DHCP server assigns network configuration information at most 253 users

accessing the Internet in the same time.

For example: If the LAN IP address is 192.168.0.1, the IP range of LAN is 192.168.0.2 to

192.168.0.51

. The DHCP server assigns the IP form Start IP Address to End IP Address. The legal

IP address range is form 0 to 255, but 0 and 255 are reserved for broadcast so the legal IP

address range is from 1 to 254. On the other hand, you cannot assign an IP great
