Security Challanges Flashcards
(15 cards)
What fundamental security challenge exists with wireless networks?
Wireless signals are publicly broadcast and can be intercepted by anyone.
How can interception of wireless signals be mitigated?
Encrypt data in transit using strong encryption protocols.
What does non-repudiation mean in wireless networks?
Ensuring the data received is from a known, trusted sender, and verifying the recipient.
How can data integrity be compromised in wireless networks?
Through interception and manipulation via Man-in-the-Middle (MITM) attacks.
What is a solution for achieving non-repudiation?
Using certificates and encryption.
What characteristics make an encryption key effective?
Long, randomized, short lifespan, difficult to guess.
Why is hiding the SSID beneficial?
Reduces visibility of the network to casual attackers.
What is the risk of using DHCP on wireless networks?
Susceptibility to unauthorized IP assignment and spoofing.
How does a VPN enhance wireless security?
Encrypts all traffic end-to-end, protecting data even on insecure public networks.
Why should you regularly update firmware on wireless devices?
To patch vulnerabilities and maintain strong security measures.
What additional security measure is useful in preventing unauthorized access?
MAC address filtering to restrict device connectivity.
What protocol significantly improved upon WPA2 vulnerabilities?
WPA3 with advanced handshake methods and forward secrecy.
What is forward secrecy in WPA3?
Ensuring captured data cannot be decrypted even if keys are compromised later.
Why might attackers prefer active sniffing?
To directly interact with and exploit target systems or networks.
What is the main drawback of WEP encryption?
Static keys and weak IV make it highly susceptible to various attacks.
