Ad-Hoc Mode definition
In general terms, ad-hoc mode is a mode where devices connect directly through a wireless connection, meaning there is no extra centralized access point or device, such as a router. In this mode, devices act as a client and access points, enabling them to communicate directly with any other ad-hoc device in the range. In terms of cybersecurity, ad-hoc mode focuses on various vulnerabilities associated with direct device-to-device wireless connections. On the flip side, as there is no centralized access point managing the connections, the security mechanisms might be less stringent, meaning connected devices could be exposed to potential threats, like unauthorized access, data interceptions, or man-in-the-middle attacks. To avoid any potential cyber threats, ad-hoc mode requires specific security measures to prevent attacks and safeguard data transmission.

Common ad-hoc mode applications in cybersecurity:
Mesh networks: Some mesh networks use ad-hoc connections for multiple data transmission paths. This design can ensure data reaches its destination, even when some nodes or paths fail along the process. Proper security measures and tools are recommended to protect against vulnerabilities from direct ad-hoc connections.
Mobile ad-hoc networks (MANETs): These networks are usually used when creating a fixed infrastructure isn’t feasible, for example, in military operations, temporary gatherings, events, or disaster recovery.
Peer-to-Peer (P2P) networks: Ad-hoc mode is often used in P2P networks where devices like smartphones and computers directly share data and resources without relying on a centralized server. The downside is that it can also expose devices to cyber threats if no cybersecurity tools are applied.
