Firewalls Security
14
What is a Firewall?

• A firewall is simply a program or hardware
  device that filters the information coming
  through the Internet connection into your private
  network or computer system. If an incoming packet
  of information is flagged by the filters, it is
  not allowed through.

Where does the term come from?

• Computer security borrows this term from
  firefighting, where it originated. In
  firefighting, a firewall is a barrier established
  to prevent the spread of fire.

15
Who uses a firewall?
An enterprise with an intranet that allows its
workers access to the wider Internet installs a
firewall to prevent outsiders from accessing its
own private data resources and for controlling
what outside resources its own users have access
to.
16
How does a firewall work?

• Packet Filtering - Packets (small chunks of
  data) are analyzed against a set of filters.
  Packets that make it through the filters are sent
  to the requesting system and all others are
  discarded.

• Proxy Server - A firewall also works with a
  proxy server that makes network requests on
  behalf of workstation users and then sends them
  the information.

17
How does a firewall work? (Continued)

• Stateful inspection - A newer method that
  doesn't examine the contents of each packet but
  instead compares certain key parts of the packet
  to a database of trusted information. Information
  traveling from inside the firewall to the outside
  is monitored for specific defining
  characteristics, then incoming information is
  compared to these characteristics. If the
  comparison yields a reasonable match, the
  information is allowed through. Otherwise it is
  discarded.

18
Firewalls are separate

• A firewall is often installed in a specially
  designated computer separate from the rest of the
  network so that no incoming request can get
  directly at private network resources.

Sample Firewall

Filtering Methods for Wiraless
There are also firewall filtering methods
for wireless communications. For example,
if you are a mobile user, firewalls allow remote
access in to the private network by the use of
secure logon procedures and authentication
certificates.
21
What else you need to know?

• IP Numbers
• Domain Names
• Protocols
• Ports

22
Products
A number of companies make firewall
products. Features include logging and reporting,
automatic alarms at given thresholds of attack,
and a graphical user interface for controlling
the firewall.

• Software

• Hardware

First, you need a computer to plug all this into.

DNS Domain Name System

• What is DNS? Translates InternetDomain names
  into IP numbers.
• e.g. www.Syntek.ws 64.119.173.201

• Install DNS Server
• Go to - Add or Remove Programs and then on Add or
  Remove Windows Components.  Then click on
  Components list, then click on Networking
  Services and then click Details, select the
  Domain Name System (DNS) check box, and then
  click OK.

DNS Cont.

• Configure DNS Server
• Start DNS Server Configuration Wizard.
• Select Add a forward lookup zone. Click Next. The
  new forward lookup zone must be a primary zone so
  that it can accept dynamic updates. Click
  Primary, and then click Next.

28
DNS Cont.
Type the name of the zone, and then click Next.
Accept the default name for the new zone file.
Click Next.
29
DNS Cont.
Type the name of the zone, and then click Next.
The zone name should match the Network ID of your
local subnet. For example, if your subnet range
is from 192.168.0.1 to 192.168.0.254, type
192.168.0 in the name value.

• Choose to add a reverse lookup zone now.
  Click Next.
• Click Primary, and then click Next.

30
DNS Cont.
Click Finish to complete the Server Configuration
Wizard.
Accept the default name for the new zone file.
Click Next.
31
DNS Cont.

• Enable Dynamic Update on the Forward and Reverse
  Lookup Zones (Optional - Recommended)
• Enable DNS Forwarding for Internet connections
• If external internet names need to be resolved
  you can configure a forwarder so that the
  requests are sent to the DNS server of the ISP or
  an external DNS server.

Overview of ISP.

• Internet Service Provider What to look for?
• 1st - What your server will be hosting?
• 2nd - Compare the upload/download stream speeds.
• Recommend Upload stream faster than download
  stream.
• For Example
• SBC Yahoo 384Kbps - 1.5Mbps/128Kbps - 384Kbps
• Charter 256Kbps/3Mbps
• ADSL (Asymmetric Digital Subscriber Line)
• Lite 64k/256k (20/mo) to Premium 512k/512k
  (140/mo)
• SDSL (Symmetric Digital Subscriber Line)
  Provides same high-quality performance
• Basic - 144 Kbps ( 150/mo) to Pro - 2.3 Mbps
  (700/mo)
