When a website address starts with "https" instead of "http," that indicates that encryption is Using a long enough random password (e.g. 14 random letters) or passphrase (e.g. 5 randomly chosen words) makes pre-shared key WPA virtually uncrackable. Authentication and authorization Determine what methods are enforced and how they can be circumvented. this content
Suppose you have a wireless network connected to the intranet and configured only for a few users. A WIPS is typically implemented as an overlay to an existing Wireless LAN infrastructure, although it may be deployed standalone to enforce no-wireless policies within an organization. The name of your router (often called the service set identifier or SSID) is likely to be a standard, default ID assigned by the manufacturer.

The infrastructure mode will have at least one AP to form a BSS. One way to test it is to see if somebody can open their browser using your network without using a password (your network devices will all share the same password). Wireless Network Security Types Figure 1: Enabling Wireless Zero Configuration in Windows XP Authentication As we have stated again and again, you will need certificates to authenticate your users. Wireless Network Security Issues For Web, not all web sites offer https, and even if they do, the browser sends out IP addresses in clear text.
Black holing Black holing is one possible way of stopping a DoS attack. http://upxpress.net/wireless-network/wireless-netork-security.php The only way to keep communication truly secure is to use end-to-end encryption. These attacks rely on the abuse of protocols such as the Extensible Authentication Protocol (EAP). Both WPA and WPA2 support EAP authentication methods using RADIUS servers and preshared key (PSK). Wireless Network Security Ppt
Also, many contracts with ISPs specify that the connection may not be shared with other persons. They also come in the hardware variety. If you choose these options, you should also choose your trusted domain name and trusted root certificate authority. have a peek at these guys One of these methods is referred to as “accidental association”.
unused Top 10 Tips for Wireless Home Network Security Search the site GO Internet & Network Tips & Tricks Basics Guides & Tutorials Installing & Upgrading Key Concepts How Wireless Network Security Projects There are two ways: Active method In the active method, the STA sends out a probe request with the SSID inside to see if an AP responds. A wireless network administrator will configure 802.1X authentication to work hand in hand with WPA/WPA2-enterprise encryption.

If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot. MAC ID filtering One of the simplest techniques is to only allow access from known, pre-approved MAC addresses. In our example diagrams we use client certificates for authentication.
Don't use passwords that can be easily guessed, such as common words and birthdays of family members. Separate your wireless network with a firewall between the AP and wired network—and don't allow wired intranet users to poke around at the management interfaces. On the client side, the wireless monitor is capable of showing you the action your wireless network client is performing.
