the device needs to be rock hard Hardening is basically making any device secure against tampering and abuse. Change default password Enforce password complexity and length requirements Use role-based access Disable unneeded network services like Telnet or VN...

im so tired i can't do this anymore i can't think Content filtering can apply Application layer filters based on HTTP data. Most firewalls and proxies support some form of content filtering. Common Filtering Criteria URL filtering Content and reputation-based...

A server that mediates the communications between a client and another server. Proxies often have filtering and tampering capabilities, as well as caching for improved performance. Proxies don't inspect traffic as it passes through like normal firewalls, but i...

separate but NOT equal mwahahahaha Effective placement of security appliances depends on segmenting the network into clearly defined areas. This is done using VLANs and subnets, where each segment is it's own broadcast domain. The main unit of a logically segm...

even bigger! even better! come on, let's go! never give up! Wifi 6 uses advanced modulation and signal encoding to improve packet transmission speeds by 40%. This grants it the title HE, for high efficiency. The goal for Wifi 6 was to achieve 10G connection sp...

i need bigger and better wifi NOW Wifi 5 only works in the 5 GHz band. 2.4 GHz support only works for mixed modes like 802.11b/g/n. The aim for Wifi 5 was to reach Gigabit Ethernet and better. Wifi 5 supports better channel bonding (up to 80 to 160 MHz channel...

the second wifi standard of all time (OAT). 802.11b uses the 2.4 GHz frequency band, and was the twin brother of 802.11a on release. It standardized the use of DSSS and CCK signal encoding. While technically inferior to 802.11a with a data rate of 11 Mbps, 802...

this is a lot of yap for a wifi standard 802.11n increased bandwidth over it's predecessors by multiplexing the signals from 2-4 separate antennae (a radio chain) using MIMO. Radio Chain Radio chains are identified using the AxB:C notation, where: $A$ is the ...

the first wifi standard of all time i think Wireless radios are configured to use a frequency band, or a section of the radio frequency spectrum. Network appliances and wireless hosts determine what bands are available to them given their adherence to the vari...

i need a map that dictates where all the ______ people are Range, interference, and signal strength all need to be considered when designing a wireless network. Network admins also need to consider device density, device movement, and special traffic requireme...

signal jamming but instead it's wifi Wifi-enabled devices should have an indoor range of 100 feet, and double or even triple that for outdoor range. 2.4 GHz better support higher ranges than the 5/6 GHz bands, but clients choose which band to use using the DRS...

i am tired of taking notes let me out of here Wireless Access Points are configured to use a MAC address for each radio usage. If a WAP has a 2.4 GHz radio and a 5 GHz radio, each of them will have a unique MAC address. Devices can join a wireless LAN using th...

yes we need to shut down three lanes of traffic to fix this pothole Many Wifi access points have dual-band or tri-band radios. Clients will use a combination of beacon messages from the access point and their signal strength to choose which band to use. Howeve...

lockdown! lockdown! this is a (maybe) drill! lockdown! lockdown! Wifi networks need to be configured with authentication and encryption settings. Otherwise, any Joe Schmoe can come along and listen to all the traffic happening over the radio waves. Wifi Protec...

miscellaneous stuff The lesson sites two more types, ad hoc, mesh, and p2p. We kinda already know those types though. Ad Hoc 802.11 defines ad hoc as an Independent Basic Service Set (IBSS). It basically says that all stations are in range of each other, and i...

i wanna walk around my house with epic amounts of internet Clients can roam around an ESA using a mesh of APs around the premises. They have to be configured with the same ESSID and security configuration. They should be configured to use different channels s...

grrr you have the three main attack vectors (yes im getting lazier and lazier with these notes, senioritis hits hard man) Rogue Access Point yeah you know what this one does Evil Twins you also know what this one does since hectina almost tried it and immedia...

i can't trust any of you. all of you are fake. except you. i trust this one person. nobody else. Zero trust architecture (ZTA) operates on the assumption that no device, whether internal or external, can truly be trusted. On every network request for resources...
