Information systems must manage the memory resources used by both the operating system and applications. When a single system supports many different uses, it becomes critical to isolate the memory used by each process to prevent it from being read or altered in an unauthorized way. In this video, Mike Chapple looks at the impact of security issues associated with memory, including memory leaks, pointer dereferencing, DLL injections, and resource exhaustion.
- Information systems must manage the memory resources used…by both the operating system and applications.…When a single system supports many different uses,…it becomes critical to isolate the memory used by each…process to prevent it from being read or altered in an…unauthorized way.…I covered the issues associated with memory overflows…earlier in this course.…You learned how attackers can exploit overflow…vulnerabilities to overwrite the contents of memory…belonging to other processes and possibly trick the…system into executing attacker provided code using…administrative privileges.…
One of the other issues that we need to watch for with…memory or any other limited resource on a system is…resource exhaustion.…Whether intentional or accidental, systems may consume…all of the memory, storage, processing time or other…resources available to them rendering the system disabled…or crippled for other use.…Memory leaks are one example of resource exhaustion.…If an application requests memory from the operating system,…
