Security concerns: SME networks can also cloud security

Ensure application Performance

Not long ago, the US Netgear Company announced its latest security threat Management series, which provides enterprise-level security performance and environment for SME networks. Lin, general manager of Netgear China, said: "The Content Security Gateway STM series for Web and e-mail security filtering combines security features suitable for small and medium sized network applications and proprietary streaming scanning technology to enable users to cope with the increasingly severe internet threat with low cost and ease of deployment."

Because SMEs often lack it expertise, solutions for them must be easy to use and cost-effective. The characteristics and advantages of STM products provide a cost-effective and easy-to-use security solution for small and medium business networks.

Netgear China technical director Yangtze told reporters: "The STM series of patented security technology is different from cheap alternative solutions, to protect against all specific types of threats, not only a small number of."

In the past, to implement these technologies often requires a lot of processor resources, need to use high-end hardware configuration. However, the Netgear STM series device adopts a streaming scanning architecture which can shorten the scan time delay.

As the basic architecture of STM series, Netgear adopts the streaming scanning technology, which can scan the network packets to the gateway in real time, so it will not cause the traffic congestion of Gateway network, so it becomes a reality to keep high throughput while applying enterprise-level security detection. "

From the functional features, STM and the market in recent years, the UTM has a very similar design concept, are based on all in one architecture design, and in the product line name also has a similar place. In a sense, Netgear to market the STM series of security products is actually a simplified version of UTM.

Out of the UTM firewall, VPN and other functions, which can improve the performance of the Web and messaging modules to some extent, coupled with a streaming scanning technology architecture, in the processing speed has obvious advantages, and this is the Netgear of STM product positioning in the SME market is one of the main reasons.

Cloud Distribution Architecture Design

According to the reporter understand, in addition to the use of patented streaming scanning technology, cloud security technology, a large number of applications and enterprise-class protection effect is also the design highlights of STM series products.

0 o'clock threat protection: In order to achieve 0 jet lag protection, STM uses a "cloud distribution" architecture to identify new security threats and proactively block new malware, phishing attacks, spam, bad URLs, and network zombies, worms, etc. before attacking the user network. It detects 2 billion events a day from a large number of data sources, such as a zero-difference malware signature, phishing attack detection, threat research, IP reputation, and so on.

Cloud Distributed spam Analysis system: Netgear's anti-spam engine uses a cloud-distributed spam analysis architecture that connects global feedback servers in a cloud-distributed way to get the latest spam messages and thus block new spam messages.

This method can achieve high spam detection rate and low misjudgment error rate. Unlike open source or other traditional spam filtering technologies, cloud-distributed spam analysis technology has a strong adaptability to detect new types of spam and can be applied to any language without any learning period. New spam is sorted and detected within minutes of appearing on the Internet.

Enterprise-class URL filtering: The URL filtering engine of STM uses enterprise-class web filtering technology to classify URLs into 64 categories for easy management. The URL filter engine of the NETGEAR STM has a huge database of more than 100 million URL entries, using the cloud security approach to connect with global service providers, and to sort and update URL entries in real time.

The URL filtering engine of the NETGEAR STM automatically updates and classifies new URLs or is not previously unknown URL in some inefficient manner, requiring an administrator to manually submit new entries individually. URL filtering not only prevents access to Web sites, but also prevents access to spyware sites.

According to Yangtze, currently STM provides three different types of products, namely STM150, STM300 and STM600. Each model has different performance, but all have the same security function, can meet the different size of SME network application needs.
