This blog post will present essay # 2 which I wrote to meet the CWNE application requirements. This essay captures the learning aspects from CWSP and CWAP exams which help me deal with the issue at a large distribution centre of a retail company in New Zealand.
I’d like to provide some tips and tricks to help one achieve the CWNP certification. The CWSP-206 Exam was revised in November 2019 from CWSP-205 with added topics on OWE/WPA3 and SAE and removing some older security concepts around pre-RSNA technologies like WEP. The exam in itself is not as hard compared to CWAP. I’d still suggest guys to take […]
Topics covered below are not in a great deal but should get the important aspects required. The below content cover 45% of the exam syllabus for CWSP-206 which means around 25-27 questions approx. Select and implement appropriate authentication solutions WPA/WPA2-Personal (Pre-Shared Key) WPA/WPA2-Enterprise WPA3-SAE and 192-Bit enterprise security 802.1X/EAP EAP methods EAP-TLS EAP-TTLS PEAP EAP-FAST EAP-SIM EAP-GTC Developer IEEE […]
802.11 Frame Exchanges section account for 25% of syllabus for CWAP-403 exam. Potentially around 15 questions out of 60 in the exam can be expected from this section. This blog post focuses on the “security” component of 802.11 Frame Exchange. I will be focusing on other sections in the subsequent posts in the next week or two. Let’s begin! Authentication […]
I am attempting to put a mind map of WLAN issues. I will look forward at expanding each one of the classifications in the revisions of this blog.
This section emphasizes on the Virtual IPs section in the FortiGate. I’ve learnt something which is not obvious behaviour and one of those ‘remind me later’ moments that I’ve encountered. VIPs are essentially Destination Network Address Translation (DNAT) objects. For sessions matching the VIP, the destination address is translated. Let us go through some examples In the above diagram, all […]
Often times we come across website which use certificates that not match the certificate of the site. It presents us with a warning message and option to proceed with risks, below image is quite common. A number of applications and website that use SSL encryption correctly. In this case, the traffic goes through a Secure Sockets Layer (SSL) and is […]
Different Authentication types Open PSK 802.1X Open Authentication – There is no authentication (Free for all). Device connects to wireless network without any issue. Open Authentication might also redirect to a captive portal like at a Airport or Public Wireless places. There is a two way packet exchange. It is not the secure way to setup the wireless. PSK / WPA/WPA2 […]
Hi IEEE 802.11 Key Concepts Let’s get started with the IEEE 802.11 Journey synopsis. Standards are defined at physical and mac-sub layer(data-link). We are referring to different ways of transmitting data over the air. Also how our communication signal would deliver information. One of the original ones we’ve come across is FHSS (Frequency Hopping Spread Spectrum) and DSSS (Distributed Sequence […]
