Definition
Ad-hoc mode is a network configuration in which devices connect directly through a wireless connection without relying on a centralized access point, such as a router.
This enables devices to function as clients and access points, allowing them to communicate with other ad-hoc devices within range.
In cybersecurity, ad-hoc mode addresses various vulnerabilities related to device-to-device wireless communications.
On the downside, lacking a centralized access point to manage the connections introduces a vulnerability. This exposes network devices to threats like data interceptions, unauthorized access, or man-in-the-middle attacks.
Common Ad-Hoc Mode Applications in Cybersecurity
- Mobile ad-hoc networks (MANETS): These networks are used to create a fixed, unfeasible infrastructure, like temporary gatherings, military operations, events, or disaster recovery.
- Peer-to-peer (P2P) networks: Most P2P networks use ad hoc mode to enable devices to share data and resources directly without relying on a centralized server.
- Mesh networks: Some mesh networks use ad hoc connections for multiple data transmission paths, ensuring data reaches its destination even if some paths or nodes fail.
