This document discusses security issues with wireless networks and protocols. It describes common wireless standards like 802.11b, g, and a. It then covers security protocols that aimed to improve on WEP like WPA and WPA2, discussing their encryption methods. The document also outlines various threats to wireless security like eavesdropping, unauthorized access, and denial of service attacks. It concludes by listing some common wireless hacking tools.
While computer systems today have some of the best security systems ever, they are more vulnerable than ever before.
This vulnerability stems from the world-wide access to computer systems via the Internet.
Computer and network security comes in many forms, including encryption algorithms, access to facilities, digital signatures, and using fingerprints and face scans as passwords.
The document discusses Wi-Fi encryption protocols, specifically examining the weaknesses of WEP encryption and how tools like Aircrack can crack WEP keys in minutes by exploiting those weaknesses. It then provides an overview of the newer WPA and WPA2 standards introduced in 802.11i to replace WEP, discussing their implementations and some initial minor vulnerabilities.
EAP (Extensible Authentication Protocol) provides a framework for authentication that allows different authentication protocols to be used. It was originally developed for PPP (Point-to-Point Protocol) connections but can work over any secure link layer. EAP uses a request-response format to negotiate authentication methods between a peer and authenticator. Common methods include identity, notification, MD5-challenge authentication, and vendor-specific protocols. While simple to implement, EAP has security weaknesses if used without a secure underlying network, highlighting the need for improved authentication methods.
The document discusses WiFi security protocols WEP, WPA, and WPA2. It provides details on:
- The security flaws of the original WEP protocol and why it was deemed insecure
- The WPA protocol which improved on WEP by implementing TKIP, providing per-packet key mixing and integrity checks to address WEP issues
- The WPA2 protocol which is defined by the 802.11i standard and implements the more robust AES encryption and integrity protection using CCMP, requiring new hardware.
Network security is important to protect vital information while allowing authorized access. Key aspects of network security include identifying vulnerabilities, threats like hackers and methods of attack, and implementing appropriate countermeasures. Common attacks include password attacks, viruses, and packet sniffing. Effective countermeasures include firewalls to control access, intrusion detection systems to monitor for exploits, IPsec and encryption to secure communications, and user education to address social engineering vulnerabilities. Comprehensive security requires backups, encryption, virus protection, firewalls, monitoring, training, and testing defenses.
Wireless networks allow devices to connect to a network without being physically connected by cables. They work by transmitting radio signals that carry data between wireless devices and access points or base stations. There are different types of wireless networks including WLANs for local areas like campuses, WPANs for personal networks using technologies like Bluetooth, and WMANs for connecting multiple networks over a metropolitan area. Wireless networks offer mobility and flexibility compared to wired networks but have lower bandwidth and speeds. Common applications of wireless networks include mobile access to the internet, extending wired networks wirelessly, and connecting remote areas without wired infrastructure.
Wi-Fi is a wireless networking technology that uses the 802.11 standard developed by IEEE to allow for wireless local area network computer communication in public spectrum bands. Securing wireless networks is important and can be done by securing all wireless devices and educating users, actively monitoring the network for weaknesses, and using stronger security protocols like WPA2 instead of the deprecated WEP. While SSL encryption provides some security, public Wi-Fi connections can still be intercepted using man-in-the-middle attacks, so using a VPN service or SSH tunneling can further improve security when connecting over unknown networks.
Wireless local area networks (WLANs) allow for mobility by using radio frequency or infrared communications instead of cables to connect devices to a network. Common WLAN standards include 802.11a, 802.11b, 802.11g, and 802.11n. WLANs use technologies like direct sequence spread spectrum, frequency hopping spread spectrum, and orthogonal frequency-division multiplexing. The 802.11 architecture defines the physical layer, data link layer including logical link control and media access control, and network topologies like peer-to-peer, access point based, and point-to-multipoint.
Router is a networking device that connects different networks and selects the best path to forward packets between them. It operates at the network layer of the OSI model. Cisco is the leading router manufacturer, making 70% of the market. Routers come in different sizes for different uses - access routers for small networks, distribution routers for ISPs, and core routers for backbone networks. Static routing requires manually configuring routes, while dynamic routing uses protocols to share route information between routers automatically.

You have persuaded XelPharms CIO that wireless networking would be.pdfarpittradersjdr
You have persuaded XelPharm\'s CIO that wireless networking would benefit many of the
company\'s employees. However, he requests that you plan the
network carefully and begin with a pilot network before migrating hundreds of clients to use
wireless technology. You decide to begin with a pilot network
in the distribution facility. The distribution facility is 200 feet long by 120 feet wide. It houses
45 employees during each shift, all on the same floor. What is
your first step in planning the pilot network? As part of your later planning, draw the network,
including the quantity and optimal placement of access points. What pitfalls, some unique to this
environment, are you careful to avoid? What wireless standard do you recommend and why?
Solution
There are many factors that need to consider before developing wireless network like cost,
bandwidth, use and devices that need to deploy in network following are some points that need
to consider for planning network
There are a number of reasons for a company to implement wireless networking. Wi-fi makes it
much easier for workers to connect to the LAN from their laptops in conference rooms, break
rooms, and other areas that may not have wired Ethernet jacks (or may not have enough for the
number of people present).
A wireless network also provides a way for you to allow visitors to access the Internet with their
laptops or handhelds (for example, to check their e-mail).Rolling out a wireless LAN within your
organization, however, is more complicated than just plugging in a wireless access point (WAP).
You need to address a number of factors in the planning stage to ensure both accessibility and
security.
Steps to pilot network:-
1) Establish a pilot that will test and confirm how wireless can work within your business
campus and needs.
2) Tie in Internet access and a robust data security system.
3) Install wireless access points, and equip notebook PCs for wireless use (e.g., provide PC cards
or upgrade to PCs with integrated wireless connectivity built in).
4) Train and turn your participants loose with their wireless notebook PCs. 5 After the pilot,
build on what you learn to broaden your wireless LAN (WLAN) to cover other areas and users.
Here are some of the things you should consider as you prepare to go wireless :-
The first step in planning your wi-fi deployment is to determine who will be using your wireless
network. This can affect network design. If the wireless network is primarily to give visitors
Internet access, you will want to isolate it from your wired LAN, perhaps by placing it in a
DMZ. If the wireless LAN is for the use of your workers, you will need to give them access to
resources on the wired corporate network without compromising the security of the main LAN.
If both outsiders and employees need wireless, you may want to establish two separate WLANs
to meet the needs of each.
The next step is to look at what type of traffic will flow over the WLAN. This analysis is
necessa.

According to the research from Harvard University, each Google search produces as much carbon dioxide as boiling a kettle of water, which is 7 grams of CO2. With 200 million daily searches on Google, this amounts to 1,400,000 kg of carbon dioxide emitted every day. However, Google claims that each search only produces 0.2 grams of CO2, which would be 40,000 kg daily. A separate study by Gartner found that information technology accounts for about 2% of global emissions currently. It was also previously calculated that worldwide energy savings of 8.3 megawatt hours could be achieved if Google's homepage was black instead of white.

3. What is Wireless Networking?
Wireless or Wi-Fi technology is another way of connecting your computer to
a network without using wires. Wireless networks utilize radio waves
and/or microwaves to maintain communication channels between
computers. This gives people the freedom to connect computers anywhere
in your home or office network.
Wireless networking works similarly to how cordless phones work, through
radio signals to transmit data from one point A to point B. A basic wireless
design typically consists of a wireless router that provides access to the
Internet and/or network and a system that connects via a wireless adapter.
4. Typical home wireless network
Home wireless networks typically consist of at least one Wireless
Access Point/Router and one or more computers that connect to the
wireless router. The Access Point/Router is the device that systems
connect to for access to the internet or to another computer sharing
the signal.

connect to for access to the internet or to another computer sharing
the signal.
5. Wireless Hardware
Wireless Router with 4 port switch
Here we see a typical
wireless router with 4
available ports to plug
computers directly into,
the wireless antenna and
one WAN port.
Wireless Network Adapters
Computers need an adapter
that is compatible with the
router in order to connect.
Most newer laptops and PDAs
already contain a wireless
adapter.
There are many different kinds
of adapters. PCMIA, PCI,
USB, and Firewire are a few
shown below.
6. A, B…..G? Current Wireless Standards
802.11A
Supports bandwidth up to 54 Mbps. It has a very limited range and has more
difficulty penetrating walls and other obstructions. These devices should
considered outdated and is not typically found in common retail stores.
802.11B
Supports bandwidth up to 11 Mbps. It has a much better range than 802.11a
and is not as easily obstructed by walls or other objects. Devices that use
this protocol can suffer from more interference from other electronic devices
such as microwaves. These devices are quickly becoming scarce at retail
stores as they are replaced by the newer 802.11G devices.
802.11G
Supports up to 54 Mbps and has a range that will cover most average homes.
These devices are still typically common in retail stores but are quickly being
replaced by the newer technologies such as 802.11N.
802.11.N
One of the newest types of wireless devices found in retail stores. Supports up
to 600 Mbps and can cover an extremely large home or small business.
7. Before you head for the store
Prior to purchasing a wireless network there a few things that you can look
for to ensure that the equipment will provide an adequate amount of
security.
• Gather as much information about your wireless hardware’s security as possible.
Advanced firewall protection, strong encryption protocols, web filtering, and MAC
filtering are just a few items you should look for in a wireless router.
• Ensure you have access to phone ,email, or knowledgebase support from the
manufacturer.
• Check the documentation that comes with the router/network adapter. Verify
that configuration and securing of the router is simple and easily understood.
8. That was easy!
Wireless networks have become extremely easy to setup these days.
Many people find that they can simply plug the hardware in and in just a
few minutes they can be surfing the web or transferring files to other
computers with no wires attached.
But perhaps it was TOO easy….
Many people you setup the wireless fail to setup appropriate security
measures on their wireless once they are connected.
If you simply plugged in your network adapter, found and connected your
laptop or PDA to your network, there’s nothing to prevent your neighbor or
someone else from connecting just as easily as you did!
9. Recommendations for Securing Your Wireless
Network at Home
1. Change the router’s default passwords.
2. Change the SSID name and disable SSID broadcast.
3. Setup MAC filters to limit which computers can connect.
4. Turn on WPA or WPA2 encryption.
5. Review your wireless logs.
6. Watch for upgrades from the manufacturer.
7. Practice good computer security.
10. Step 1. Change the router’s default passwords.
Most wireless router manufacturers provide Web pages that allow
owners to enter their network address and account information.
These Web tools are protected with a login screen (username and
password) so that only the rightful owner can do this. Right out of
the box, however, they are usually configured with a default
password that is too simple and very well-known to hackers on the
Internet. Change these settings immediately.
11. Step 2. Change the SSID name and disable SSID
broadcast.
Access points and routers all
use a network name called the
SSID. Manufacturers normally
ship their products with the same
SSID set. For example, the SSID
for Linksys devices is normally
"Linksys." When someone finds
a default SSID, they see it is a
poorly configured network and
are much more likely to want to
snoop around.
In Wi-Fi networking, the access
point or router typically
broadcasts the network name
(SSID) over the air at regular
intervals. In the home, this
feature may be unnecessary,
and it increases the likelihood an
unwelcome person will try to log
in to your home network.
12. Step 3. Setup MAC Filters.
All network communication
devices have unique hard
coded numbers assigned
to them. This number is
called the “MAC” address.
If your router is capable of
MAC filtering you should
only allow devices that you
expect to appear connect
to your wireless network
and deny all others.
13. Step 4. Turn on WPA / WEP Encryption.
Understanding WEP vs. WPA2
WEP (wired equivalent privacy) was the encryption
scheme included with the first generation of wireless
networking equipment. It was found to contain some
serious flaws which make it relatively easy to crack,
or break into within a matter of minutes. However,
even WEP is better than nothing and will keep casual
snoopers and novice hackers out of your wireless
network. Using encryption with a longer key length
will provide stronger security, but with a slight
performance impact.
WPA (WIFI protected access) is a much stronger security
protocol than WEP and should be used instead of
WEP if your wireless router and network adapters will
support it. Some routers may refer to this as WPA-
PSK.
You should always consider using the router’s
strongest encryption mechanism.
All Wi-Fi equipment supports some form of "encryption“, which scrambles the information
sent over the wireless network so that it can’t be easily read. WEP or WPA are the most
common encryption schemes found on home wireless systems. For most routers, you will
provide a passphrase that your router uses to generate several keys. Make sure your
passphrase is unique, not a dictionary word and at least 10 characters long – the longer, the
better!
14. Step 5. Review wireless Logs.
Most routers will keep track
of what systems have been
successful or have failed to
connect to your router.
Reviewing your logs can
help identify a possible
intruder or misconfiguration
in your routers security.
15. Step 6. Watch for firmware upgrades for devices.
Network hardware is run by software called firmware. Just like computers, flaws may be found in
the software that would allow people to bypass security mechanisms built into your router or
network adapter. You should regularly check your wireless manufacturer’s website for updates
and apply when appropriate.
16. Step 7. Practice good computer security.
Don’t rely only on your router/access point to protect your computers inside your wireless
network. Even the most secure wireless network typically won’t stop a determined hacker.
• Enable System Firewalls
• Use accounts protected with a strong password
• Apply security patches to your OS in a timely manner
• Ensure you have antivirus up to date on your system
• Avoid using open shares on your computers to share files
• Be on the lookout for malicious websites, spyware/adware, phishing and scams

17. How can I confirm my setup is secure?
When connecting to your
wireless network. Look
for “Security-enabled
wireless connection”.
If your home network
connection is listed as
“Unsecured”, you may be
a sitting duck to
individuals free-loading off
your internet connection
or snooping around on
your computer.
20. Free Wireless On The Road
• Many businesses now provide some form of
free wireless internet access.
• Airports
• Cafés
• McDonalds
• Starbucks
• Panera Bread
• Even some gas stations??
21. Can I connect?
Generally (but not always) the network will have a
name that matches the business.
If in doubt, ASK!
• There are examples of places that have open access but
never intended to provide that to the public.
• The laws on access to networks are strict and don’t fit well to
the grey areas in wireless access but may well be applied to
you anyway.
22. How to Find an Open Wireless Network with
Windows XP
– Windows normally provides notification of
wireless networks in range and lists the names.
– You can then select the network you wish to
connect with and click “Select”
23. How to Find an Open Wireless Network
with Mac OS X
– MAC OS X
provides a similar
notice when the
Airport icon is
available and the
airport is on.
– Click the Airport
icon and select
the network from
the list to connect
to it.
24. It Looks Open…but Should You
Connect?
How do I know the terms of
access?
– Many locations use a type of portal to
gain access. You must read and
agree to the terms before you are
allowed on the net. Those terms are
binding.
If you are not presented with any
terms or acceptance screen?
– Be wary. You don’t have to know the
networks terms of use to be held to
them. It doesn’t have to make sense
it’s just the law.
25. Wireless on the Road: The good…
• Convenient
• It’s always nice to be able to stay connected on the road.
• It is becoming more widespread and almost expected in hotels
and other travel locations.
• More freedom when working on the road
• Allows a teleworker the freedom to get out of the house.
• Allows for easier use of vacation even if critical actions need to
occur while you are away.
26. Wireless on the Road: The bad…
• Legal grey areas
– Some businesses can be vague about what the terms are to use
the access.
• Often times can be poor quality
– Many locations implement wireless poorly and the signal is weak
in the intended areas.
– This makes it much easier for a hacker to setup a fake wireless
router and fool you into thinking you are connecting to a
legitimate wireless network.
• You have no idea who your neighbors are
– Open wireless is by nature uncontrolled and any one with any
intentions can be there with you.
– Are you sure that “McDonalds” is really McDonalds?
27. Wireless on the Road: The Downright Ugly…
Really nasty stuff:
• Large open WiFi networks are just like being on the Internet
• There can be hundreds of people with unknown
intent who are all on the same physical network as
you, just as though they were inside your house.
• Your system is wide open to anything if not using a
firewall.
• Detection and identification of the offender are harder
than it would be on the net
• Automated tools are emerging to take advantage of systems
on wireless networks
• While not necessarily simple today, they will improve with time.
• Moving towards automatic discovery and exploitation of systems.
28. Recommendations for Using Wireless on the Road
• Disable automatic connections even to
preferred networks.
– This prevents scanners from gathering the
list of wireless networks that windows will
automatically connect to.
• Keep Antivirus products installed and
up to date. This is pretty general advice
but it holds here too.
• Enable the windows firewall whenever
you are working with public wireless.
– All but the most determined attacker will be
seriously frustrated in attempts to attack a
firewall enabled system. It raises the bar.
29. Recommendations for Using Wireless on the Road
• Turn off or disable your wireless card when not in use.
• Ensure your system is patched and up to date.
• Use the auto update features of your OS to reduce the
number of possible exploits available to an attacker.
• Don’t access personal or sensitive information while on a
public wireless network (e.g., banking sites.)
32. Are you using Wireless on Campus?
• How many people here use wireless on
campus?
• How many people use wireless for palm or
pocket PC devices?
• How many people use wireless for Tablet or PC
devices?
33. SSIDs on University Campus
• University-Wireless
• unsecured, broadcasted, “guest”
• KUMC-Wireless
• secured, non-broadcasted, staff/faculty/special
permission only
34. University-Wireless SSID
Most broadcasted SSIDs are used in hot spots
such as coffee shops, hotels, and etc. Here at
KUMC we have one SSID that is broadcasted –
the “University-Wireless” SSID. This allows
devices to connect to the wireless network
easily; however, this method is less secure than
other types of “encrypted” wireless connectivity.
35. KUMC-Wireless SSID
Did you know there are 2 SSIDs on campus?
We already mentioned the less secure “University-Wireless”
SSID, but did you know that there is a more secure SSID
named “KUMC-Wireless”? The KUMC-Wireless SSID uses
WPA encryption to secure the traffic from Access Point to
wireless devices.
36. KUMC-Wireless and WPA
• Daniel mentioned WEP and WPA earlier.
• WPA offers a more secure connection and
rather than having a static key provides a
method of key rotation where the Access Point
and wireless device change keys at certain
intervals.
• The key exchange method used on the “KUMC-
Wireless” SSID is known as Temporal Key
Integrity Protocol (TKIP) and is extremely hard
to hack.
37. Wireless Security on Campus
We strive to provide the most secure environment
possible using the KUMC-Wireless SSID. The method
of communication between wireless devices and
Access Points should be considered carefully. Basic
web traffic and synchronization with other encryption
methods between server and client are a good choice
to be used on the less secure SSID University-
Wireless. If communication between devices requires
a more secure connection then choose the KUMC-
Wireless SSID and have a customer support
representative help you connect to our network.
38. A Secure Connection – KUMC-Wireless
Let’s get started. Right click on Network
Neighborhood or choose Network and Internet
Connections from the Control Panel.
42. Authentication Type Properties
• Choose Properties (right below the PEAP option).
• Uncheck “Validate server certificate”. (we’re using an
internal certificate.
44. Click OK OK OK OK OK OK…….
Click OK on all boxes to get back to the desktop
/ Wireless Network Properties
45. Click on Ballon – Enter credentials
In the system tray, you’ll notice a balloon that
pops up asking for credential information. Click
on the balloon and fill in the User Name and
Password Fields only.
Click OK and
you’re done!
46. Pushing the Limits: Wireless
and the Law
Sherry Callahan, Director of Information Security
49. Look, but don’t “touch”!
• Wardriving, warflying or war-anything is NOT
illegal.
• Capturing traffic is also not illegal but, in some
states, intent is the key.
• Just because a wireless network is unsecured ,
it’s not an invitation to use them.
• If you connect to a wireless network without
permission, you are committing a felony under
Kansas or Missouri law.
