Questions On Securing Wireless Client Devices

Authentication: 802.11 defines authentication services to control LAN access to a level equal to a wired link because wireless LANs have limited physical security to prevent unauthorized access. Every station, whether part of an independent BSS or an ESS network, have to use the authentication service prior to establishing a connection with another station with which it wishes

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.

Wifi-AP use a Share password is very dangerous. For example, if the wireless network connected to the company's internal resources, then the password leak is very troublesome, user complained is change wifi-ap password.

In general, wireless routers control access to their management interface by using the hypertext transport protocol (HTTP) as the default authentication protocol. In other words, when you connect to your wireless router from a web browser (typically http://192.168.1.1), and then submit your login credentials, the HTTP protocol is used to transmit your login credentials to the router. Because HTTP does not provide encryption, your login credentials are sent to the router over the air in clear-text. In this case, an attacker eavesdropping on your WLAN would be able to capture this information and use it to access the router as an administrator. Once your router is compromised an attacker can then use it to stage attacks such as man-in-the-middle (MITM), modify unencrypted data, or even send users to evil twin websites.

The network level security will form the relationships of authentication, encryption and authorization for the wireless network and its connectivity between wireless clients to the internal network. Some recommendations are:

Routers will have firewalls on them checking whether or not the information coming onto the network is allowed.

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

The latest wireless security protocol out today is WPA2 (Wi-Fi Protected Access 2) this protocol is considered the most secure wireless protocol available. WPA2 is used to encrypt your data by prompting a user to enter a password for each device attempting to log on to your network. Most modern routers on the market today are equipped with this protocol. Other measures you can take to keep the information on your network safe would be to implement MAC filtering, this will only allow devices with a registered MAC address to be on your network. Enabling a VPN is another useful method to add extra security and privacy to your network. If I were to purchase a router for myself I would purchase the Netgear AC1200 smart router, it is relatively affordable with a cost of $76.45. It offers a dual-band setup, a USB port and a variety of management

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

There are many different vendors providing various WIPS systems or more complex security solutions all in one. All of them provide the most important feature from the WIPS attack discovery options, to detect rogue access points and unauthorized connections, client devices and ad hoc networks. One of them is Cisco Adaptive Wireless IPS, this uses a network controlled system (NCS) that generates flags as rogue

The WPA2-Enterprise mode provides the security needed for wireless networks in business environments. Though more complicated to set up, it offers individualized and centralized control over access to your Wi-Fi network. Users are assigned login credentials they must present when connecting to the network, which can be modified or revoked by administrators at any time.

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

Enhancing the security of routers is important to avoid unauthorized users change configuration settings and avoid unauthorized information and routing from entering. For instance, clear text authentication takes advantage of more flexible key management capabilities.

Scenario - You are an Information Security engineer for a midsized company. The company would like to offer direct sales of its “WigIT” app to its consumers on the World Wide Web. Your manager has asked you to prepare an informational paper for the Chief Executive Officer (CEO) on wireless and mobile risk management. What risks do you envision and how will

A wireless computer can "roam" from one access point to another, with the software and hardware maintaining a steady network connection by monitoring the signal strength from in-range access points and locking on to the one with the best quality. Usually this is completely transparent to the user; they are not aware that a different access point is being used from area to area. Some access point configurations require security authentication when swapping access points, usually in the form of a password dialog box.
