6 free network vulnerability scanners
Though you may know and follow basic security measures on your own when installing and managing your network and websites, you'll never be able to keep up with and catch all the vulnerabilities by yourself. Vulnerability scanners can help you automate security auditing and can play a crucial part in your IT security. They can scan your network and websites for up to thousands of different security risks, producing a prioritized list of those you should patch, describe the vulnerabilities, and give steps on how to remediate them. Some can even automate the patching process. + ALSO ON NETWORK WORLD 8 free Wi-Fi security tools + Though vulnerability scanners and security auditing tools can cost a fortune, there are free options as well. 1.

HTG Explains: The Difference Between WEP, WPA, and WPA2 Wireless Encryption (and Why It Matters)
Even if you know you need to secure your Wi-Fi network (and have already done so), you probably find all the encryption acronyms a little bit puzzling. Read on as we highlight the differences between encryption standards like WEP, WPA, and WPA2–and why it matters which acronym you slap on your home Wi-Fi network. What Does It Matter? You did what you were told to do, you logged into your router after you purchased it and plugged it in for the first time, and set a password. WEP, WPA, and WPA2: Wi-Fi Security Through the Ages Since the late 1990s, Wi-Fi security algorithms have undergone multiple upgrades with outright depreciation of older algorithms and significant revision to newer algorithms. Wired Equivalent Privacy (WEP) Wired Equivalent Privacy (WEP) is the most widely used Wi-Fi security algorithm in the world. WEP was ratified as a Wi-Fi security standard in September of 1999.

Wi-Fi Protected Setup Flaws Make Wireless Network Brute-force Attacks Feasible
Design flaws in the Wi-Fi Protected Setup (WPS) wireless standard can make it easier for attackers to obtain access codes for secured wireless networks by brute force. The vulnerabilities identified by security researcher Stefan Viehbock affect a large number of WPS-enabled routers and wireless access points. The WPS standard was created in 2007 by the Wi-Fi Alliance in order to provide non-technical users with a simple method of setting up wireless networks. The standard supports several Wi-Fi authentication methods including one that requires pushing a physical button on the router and one that uses a predefined PIN number printed on a sticker by the device manufacturer. The PIN-based method is mandatory for WPS-certified devices, which support it by default. The WPS PIN is an eight-digit random number. The main problem lies with how devices respond to failed WPS authentication attempts. The U.S.

IPv6: The security risks to business
Predictions about when the world will end are about as consistent as the predictions about when IPv4 internet addresses will finally run out, but some IT security professionals say that is really the least of our worries. A much bigger concern, they say, should be the security holes that will open up in many business organisations as the world moves over to internet protocol version six (IPv6). This is an important aspect of the changeover that has been lost in all the hype around how IPv4 is about to run out of IP addresses assigned to each internet-connected device because of the explosion of internet users, devices and web services. IPv6 will solve this problem because it provides over four billion times more addresses than IPv4, but in solving that problem, it could expose businesses to cyber attacks as hackers use IPv6 to bypass security controls and filters designed and configured for IPv4 traffic.
