Securing Windows with EMET


The enhanced Mitigation Experience Toolkit (EMET) is designed to

Software vulnerabilities and exploits have become an everyday part of life. Virtually every product has to deal with them and consequently, users are faced with a stream of security updates. For users who get attacked before the latest updates have been applied or who get attacked before an update is even available, the results can be devastating: malware, loss of PII, etc. 

Security mitigation technologies are designed to make it more difficult for an attacker to exploit vulnerabilities in a given piece of software. EMET allows users to manage these technologies on their system and provides several unique benefits:

Since its introduction in 2003, the network has consisted of "supernodes" made up of regular users who had sufficient bandwidth, processing power, and other system requirements to qualify. These supernodes then transferred data with other supernodes in a peer-to-peer fashion. At any given time, there were typically a little more than 48,000 clients that operated this way.
