Discover the definition of the term Buffer Overflow presented by Les Assises de la Cybersécurité.

BUFFER OVERFLOW

A popular attack technique that allows the attacker to illegitimately occupy part of the system's memory from the memory space allocated to a vulnerable legitimate application. To do this, the poorly designed application must not control the size of the information supplied to it by the user. By providing more data than expected, this allows some of it to 'overflow' the application's memory zone and pollute that of the system or other applications, causing crashes at best or, in some cases, enabling illegitimate access.

Contrary to what was suggested by a famous quiz offered at the 2018 Assises, a buffer overflow has nothing to do with the beach or the swimming pool.
