Section 16: Securing Networks Flashcards
Default Accounts. How do you secure them?
Change them to something not easily guessable; change default passwords
Privilege Escalation
Occurs when a user is able to gain the rights of another user or administrator
Backdoor
A way of bypassing normal authentication on the system
Crosstalk
Occurs when a signal transmitted on one copper wire creates an undesired effect on another wire
Protected Distribution System
Protected and secured form of cable management for physical protection
How do you secure WiFi Devices?
Disable SSID broadcast and change default admin credentials
Evil Twin
A rogue, counterfeit, and unauthorized WAP with the same SSID as your valid one
WEP
Original 802.11 standard that is not secure at all and is easily broken (IV)
WPA
Replacement for WEP which uses TKIP, Message Integrity Check (MIC), and RC4 encryption (RC4 and TKIP)
WPA2
802.11i standard to provide better wireless security featuring AES with a 128-bit key, CCMP, and integrity checking (CCMP and AES)
WPS
It’s bad; disable it
Reducing Attacks for Wireless Access Points
Try to not radiate the signal outside the immediate area that it’s needed; for example, don’t let it go out into the parking lot; turn down the power level, use directional antennas
Jamming
Intentional radio frequency interference targeting your wireless network to cause a denial of service condition
WPA3
equivalent cryptographic strength of 192 bits in WPA3- Enterprise mode; enterprise mode uses AES-256 encryption with a SHA-384 has for integrity checking; personal mode uses CCMP 128 as the minimum encryption required for secure connectivity; removes the PSK exchange
Bluesnarfing
takes information
