===== Main Memory Encryption (MME) =====

**Main Memory Encryption (MME)** can be utilized to protect a system against a variety of attacks.  While data 
is  typically  encrypted  today  when  stored  on  disk,  it  is  stored  in  [[dido:public:ra:xapend:xapend.a_glossary:d:dram]]  in  the  clear.   This  can  leave  the  data 
vulnerable to snooping by unauthorized administrators or software or by hardware probing.  New [dido:public:ra:xapend:xapend.a_glossary:n:nvs]] [[dido:public:ra:xapend:xapend.a_glossary:d:dimm]] technology (NVDIMM) exacerbates this  problem since  an NVDIMM  chip can be  physically removed 
from a system with the data intact, similar to a hard drive.  Without encryption any stored information such as 
sensitive data, passwords, or secret keys can be easily compromised.
