3. What is wireless security?
Wireless: to have no wires when connecting to another device or location
Network: the grouping of two or more computers to one another
Security: to ensure that all information is kept protected and available to users who are authorized
Can also involve data encryption along with uing a id and password to access information

4. Wireless security deals with mainly the same concepts of security on a regular computer in most ways
You have to have a set up that protects your information from unwanted sources.
Having a setup makes it easier to prevent this from happening
network your using radio signals to communicate with others through a network.
using radio signals, other devices can pick up your signal when you’re traveling outside of your network

5. Other users can send and receive information without you even knowing about it

6. Steps to take before using wireless networks
Secure either your router or access points
Broadcast your service set identifier (SSID)
Allows others to view your network and try to compromise your network
Instead of using encryption privacy, try enabling your Wi-Fi protected access
Its easy to exploit weakness of wireless encryption privacy
Use MAC filtering controls
You can assign access to only networks in your system or those that know about your network
Disable your remote admininstrator
Should only be used when specifying a known IP address
Anyone can find and get access to your network and make changes

7. Wired equivalent privacy
Also known as W.E.P
Intended to provide a level of data privacy that is the same to a wired network
Seeks to establish similar protection to the offered by the wired networks physical security measures by encrypting data transmitted.
Protects the vulnerable wireless link between clients and access points

8. War driving/War chalking
This is a big threat when in comes to web security
D: The act of driving around in a vehicle with a laptop computer, an antenna and an wireless LAN adapter to exploit existing networks.
also calls phone numbers to find unprotected modems
C: resource of locating wireless networks for everyone to use
marking buildings in the area of wireless networks.
exploits wireless networks that have ranges that extend outside the perimeter of buildings
In order to gain free internet access or illegal access to an organization’s data
The idea is to provide a visual clue indicating the presence of wireless networks so that people can obtain a free Internet connection

10. Packet Sniffers Defined:
a piece of a message transmitted over a packet-switching network
contains the destination address in addition to the data.
are often called datagram’s. (in IP networks )
It can be good and bad
reads your information as it comes across the network without you even knowing.
troubleshooting problems with network communications

11. Con’t example : There is software to prevent this from accruing
if you’re sending information through an Ethernet network, all your information will be sent out like a relay for every PC to see.
All the PC’s on the network should ignore it because it has a certain destination that it has to go
There is software to prevent this from accruing
Ethereal Freeware
Analyzer 2.1 Freeware
Dsniff 2.3 Freeware

12. How to manage the web server security
Remove all unneeded services from your web server. An unneeded service can become an avenue of attack
Disallow all remote administration unless it is done using a one-time password or an encrypted link
Limit the number of persons having administrator or root level access

13. Log all user activity and maintain those logs
in an encrypted form on the web server
store them on a separate machine on your Intranet

14. Intrusion Detection Systems
very important when it comes to network security
able to find out which network access has to be monitored
more successful way to patrol your network for anything that is out of the ordinary on your network
Started as a patrol of the standalone computer but it quickly evolved to a form of detection that had little to know limits
beginning to develop detection systems that detect potential and some of the actual network invaders

15. Con’t
Have the ability to create and decide which profile of expected user behavior
Example: continuous log in attempt can lead to the network thinking that there is a hacker involved
Send out a network issue message to inform the system admin
Never overlook the messages that the network send you

16. Goals for IDS detecting attacks that involve the network
scanning over the different hosts
actually have the ability to create and decide which profile of expected user behavior

17. Problems
Public web servers continue to be attractive targets for hackers seeking to embarrass organizations or promote a political agenda
denial-of-service attack
pornographic material
posting of political messages
deletion of files
the placement of malicious software

18. Solutions Follow known best practices
Apply software patches as soon as they are announced by your incident response team or your vendor.

19. Conclusion
In summary after doing the research on wireless networks and security there are much to be learned and much to be discover. Everyday new technology is either invented, changed or updated. There are many hackers out there who try to compromise the networks whether its wireless networks or just networks systems. The only safe guards to secure your networks are to always be monitoring your systems. The debate what is actually better or secure is really up to the hackers that are able to exploit the systems. Only time will tell until there is a safe wireless network.
