Study Notes
Ad-Hoc Connection Attack
- Ad-hoc networks allow data sharing among clients, but they are inherently insecure and lack strong authentication and encryption.
- An attacker can easily connect to and compromise a client operating in ad-hoc mode.
Jamming Signal Attack
- Jamming signals can cause a DoS (Denial-of-Service) attack on wireless networks.
- An attacker can send 2.4 GHz jamming signals to disrupt network communication.
Evil Twin Attack
- An evil twin is a rogue AP that pretends to be a legitimate AP by imitating its SSID.
- Attackers set up an evil twin outside the corporate perimeter and lure users to sign in to the wrong AP.
- Once associated, users may bypass enterprise security policies, giving attackers access to network data.
Rogue AP Attack
- A rogue AP can be used to hijack the connections of legitimate network users.
- Unauthorized APs can allow anyone with an 802.11-equipped device to connect to a corporate network.
- Attackers use rogue APs to hijack connections and gain access to network data.
Bluesnarfing
- Bluesnarfing is the theft of information from a wireless device through a Bluetooth connection.
- Attackers can access the victim's contact list, emails, text messages, photos, and business data stored on the device.
Disassociation and De-authentication Attacks
- Disassociation attacks destroy the connectivity between the AP and client.
- De-authentication attacks make the victim unavailable to other wireless devices.
- Both attacks are forms of DoS attacks on wireless networks.
MAC Spoofing
- Attackers can spoof the MAC address of a wireless LAN client to masquerade as an authorized client.
- This allows them to eavesdrop on sensitive information.
Security Risks
- Employees taking corporate laptops to public Wi-Fi networks pose a significant risk to company data.
- Ad-hoc networks, evil twins, rogue APs, and other attacks can compromise enterprise security policies.
Learn about the Evil Twin attack, a type of Information Security attack where an attacker sets up a rogue Wi-Fi access point with the same SSID as a legitimate network. Understand how this attack can bypass enterprise security policies and gain access to network data. Prepare for the Certified Cybersecurity Technician Information Security Attacks Exam 212-82.
