Attacks on system resources
A communications device is a dedicated computer, and this computer has computer resources that can be attacked. In this section, we talk about potential attacks on these resources and how we can protect against them.
Memory-based attacks, memory leaks, and buffer overflows
Memory leaks are static or dynamic memory resource allocations of memory that do not serve any useful purpose. This can be due to a software bug, inefficient software, or attacks that consume memory resources.
Memory-based attacks and causes of memory leaks
Memory leaks can be any of the following:
- An application that continually stores data in memory, without releasing the memory for other applications.
- An inefficient application that locks a large amount of memory without a real need for it, prohibiting other applications from accessing this part of the memory.
- An attack on device resources that consume a large number of memory resources. This can be anything...
