NetQin Introduces Mobile Security Cloud Model at Wireless Security Symposium

SEOUL, South Korea, August 31, 2010 - The first mobile security cloud model was introduced by Dr. Lin Yu, CEO
of NetQin Mobile Inc., today at the Wireless Security Symposium held in
Seoul, South Korea. The mobile security cloud model is composed of three
parts, (1) a cloud security platform — knowledge repositories including
mobile viruses repositories, spam message repositories, phishing site
repositories, (2) high-efficient engines in the "mobile terminal" (e.g.,
virus scanning engine, intelligent spam-identification engine) etc, as well
as (3) a cloud security center that processes all the analysis work at the
backend and then distributes to the cloud security client, e.g. mobile
terminals. The mobile security cloud model gives service providers a scalable
ability to solve new emerging mobile security issues, according to Dr. Lin
Yu.

Mobile security cloud refers to collecting large amounts of virus
samples, malware, malicious websites, etc. to form a mobile security
knowledge repository, and handling security threats through an efficient
virus scanning engine and a spam message filtering engine based on the mobile
security knowledge repository. With the contribution of millions of users
around the globe, NetQin's Mobile Security Center has the most comprehensive
Mobile Security Policy Database. In NetQin's mobile security cloud model, the
user becomes a part of mobile security cloud — each time the users access
NetQin's services, they can contribute new security knowledge to NetQin's
mobile security cloud by reporting virus samples, malicious URLs and rating
other applications. Thus, the more users, the more powerful the mobile
security cloud platform is.

"As mobile phones become the information centre connecting people with
the world, mobile security is becoming a fundamental service for mobile life.
Users will require more timely and proactive protection to their mobile
devices. The user-centered design of NetQin's mobile security cloud platform
allows NetQin to collect the large quantity of mobile virus samples and spam
message samples, process them via the cloud-server and then update to the
latest policy database for the users, thus providing a timely and efficient
security protection for the users," says Dr. Lin Yu.
