What Are Two Valid Weaknesses Of Utilizing Mac Filtering For Controlling Wireless Network Access?3/18/2019 Just when you thought your wireless network was locked down, a whole new set of exploits and hacker tools hits. WPA2, PEAP, TTLS or EAP/TLS can shore up your network, if configured properly. Securing clients is a lot more difficult. These topics and more were addressed by Joshua Wright in this recent Network World chat. Wright is famous for his irreverent security blog WillHackforSushi.com. He is also the author of the six-day SANS Institute course, Assessing and Securing Wireless Networks. Plus he's a popular speaker at a long list of security conferences.

Our guest today is Joshua Wright -- famous for his irreverent security blog (although, he says, he'd really rather hack for the challenge, not for raw fish.) He is also the author of the six-day SANS Institute course, Assessing and Securing Wireless Networks. To improve the security of your Wi-Fi network, consider using MAC address filtering. Other wireless access points include an optional feature called MAC address. Access Control, and some D-Link routers in ADVANCED > NETWORK FILTER. An attacker still needs to know one of the valid addresses for that network in. Click Security from the controller GUI, and then click MAC Filtering from the left side menu. The MAC Filtering window appears. Click New in order to create a local database MAC address entry on the WLC. In the MAC Filters > New window, enter the MAC address, Profile Name, Description and the Interface Name for the client. Here is an example: Click Apply.

Hopefully you have some killer questions for me about wireless security, hacking, sushi or 1975 AMC Gremlin restoration (my first car). So, hit me up and I'll do my best to answer as many questions as we have time for. Josh_Wright: Her name was Phoebe, by the way (the Gremlin). Moderator-Keith: While we await the onslaught of questions for Josh, we will provide a pre-submitted question that Josh has already answered. Q: In general, how well are enterprises securing their wireless network? Josh_Wright: Enterprises are doing. ![]() We are seeing fewer open networks and more organizations moving to WPA/WPA2 from WEP. There is still more than a fair share of WEP networks, sometimes motivated by the need to support legacy wireless clients (such as VoIP phones, or Symbol scanners). A lot of the enterprises I talk to feel comfortable with the security of their WPA/WPA2 networks, but they often fail to realize that this is only one piece of a wireless security strategy. Failure to address client configuration and security issues, rogue detection and home/mobile users leaves organizations exposed to attack. Atome: What is your point of view on overlay vs. Integrated wireless IDS/IPS solutions? Immediately after clicking on ' Next' button, it will give rise to scanning process.

Figure A: Main Screen Step 2: Soon after the selection of the ' Recover Deleted Photos' option, select the drive from which the images needs to be recovered. Then, among them click on “ Recover Photos” option efficiently. Josh_Wright: Overlay vendors often have a strong product, since overlay vendors ONLY make wireless intrusion detection system (WIDS) products. Vendors that have to do WIDS and wireless transport and hardware and all the QA and testing that goes along with it have more to worry about, and may not have as sophisticated a product.That said, overlay products are vulnerable in that they don't have knowledge of the encryption keys used on the network - they can only look at Layer 1 and Layer 2. Integrated vendors have the advantage there, where they can look at all the traffic on the network, analyzing not only Layer 1 and 2 but all the way up to Layer 7 as well (but not Layer 8 and 9, which are money and politics, as we all know;) [Note, for more information on WIDS, check out Josh's.] Mw: How secure is WPA-PSK or WPA2-PSK? Josh_Wright: PSK-based authentication mechanisms are notoriously vulnerable to offline dictionary attacks. I wrote one of the first WPA/WPA2-PSK attack tools 'coWPAtty.' 'coW-PAtty' -- like the cow excrement). How to make chrome default browser mac os x 2017. Newer tools such as Aircrack-ng are even faster. The main problem with PSK mechanisms is that the same shared secret is stored on all devices. I was talking to a customer who was doing handheld credit card transactions with a wireless device using WPA2-PSK. They were PCI compliant (since PCI requires WPA or all kinds of hoops with WEP), but they were vulnerable in that as devices were lost, stolen or turned in for service, the PSK was disclosed and available to anyone who could get their hands on the device. Enterprises should use 802.1X instead of PSK based authentication strategies for stronger authentication and unique, per-user keys.
