Essay about Wireless Network Security – How Secure Is It?

“Family Traits” Deidre Hocevar Professor Veselits October 10th, 2012 EN 101-15 Final Draft Acknowledgements I would like to thank the following peer reviewers for their excellent input on my essay.

While wireless is often considered Ethernet, it uses CSMA/CA (Carrier Sensing Media Access/Collision Avoidance). Wireless network security and signal interference has been a real concern for network administrators. Most of these concerns have been addressed, but the reputation of being a largely free and wide-open media still lingers.

4. Block your WIFI An unsecure WIFI network is the equivalent of an unlocked front door. You don’t leave your office unlocked over night therefore you shouldn’t leave your WIFI unlocked. Protect your WIFI with a strong password made up of the criteria described in tip number 1.

• Flexibility and mobility • Ease of installation • Lower implementation costs Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

Users that have a wireless LAN should add security to ensure only intended users have access. Some safeguards include use of WEP (Wired Equivalent Privacy) encryption, IPsec, WPA (WiFi Protected Access), with a firewall or DMZ. A DMZ (demilitarized zone) is a physical or logical sub-network that separates the LAN from other entrusted networks

Dedication This book is dedicated to my husband, Zarak Johnson, who tolerated my barking when the pressure was on and catered to all of my whining. The need to live longer and push forward with this struggling and dedicated research while focusing on setting an example in life for my children,

To the peers of the researchers that gave courage and support in pursuing in making this research.

Presentation: The diction and syntax is clear, and the information presented is easily accessible to the audience. The piece is presented as a literature review and works well within the genre. Score: 4

In an effort to improve security, the Public Safety Wireless Networks (PSWN) program in coordination with the Department of Justice took action to create the Public Safety Communications Security Awareness Guide and focus on solutions to security issues. Therefore, this paper will provide a summary of wireless communications issues and address issues as various agencies cooperate, coordinate, and use interoperable digital technologies to meet public safety requirements. I aim first to discuss communications system security, identify vulnerabilities and address how critical physical, network, communications, and administrative security components operate to protect against intrusions. The final section will include PSWN program, federal, state, and local agencies proposed solutions to improve security

Network Security 1. What is network security? Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

Running head: WIRELESS AND MOBILE SECURITY PLAN Wireless and Mobile Security Plan Patrick C. Behan Regis University Context: Our networks are becoming more vulnerable because of wireless and mobile computing. Ubiquitous devices can and do pose a significant vulnerability. In this activity, you are to think outside the box and determine how to best defend
