3G the first number up to the "special" user

Beijing TD test numbers do not release the number of more than 2000

Sources said the network made the first batch of TD-SCDMA 3G terminal and the number has been distributed to users. The next period of time, Beijing will be issued in batches TD-SCDMA mobile phone number. This is expected in Beijing, Qingdao, 5 to release 2 million numbers will be mainly concentrated in the competent ministries, operators and other user-friendly hands.

3G so we wistfully IC pictures

A well-informed sources, he has received from Beijing, Qingdao, two of the TD-SCDMA mobile phone call, the voice clear.

The news from China Netcom, Beijing plans to gradually release this month on the 10th TD-SCDMA mobile phone and number, issuing a total of about 1,000 numbers.

Sources said Beijing's TD-SCDMA test network of the main building along the Chang'an Avenue and North Fourth Ring Road, this is because the Ministry of Development and Reform Commission and other policy-making departments in the Chang'an Avenue, while Datang Mobile and other major R & D units in the North 4 Central, currently in Beijing to use TD-SCDMA mobile phones will be these people.

After news that Beijing will issue 3G numbers 5000, but analysts say this argument is based on 20,000 more numbers in the four cities, the calculation of equalization come. Beijing is not the main test TD-SCDMA, the network compared to the scale of construction in Qingdao, Baoding and Xiamen to be small, so no amount will not exceed 2,000.

Massive release mobile phone numbers on the TD-SCDMA in order to carry out the practical application of environmental testing, which requires a certain call volume users to test the stability of TD networks, voice transmission quality.

2G mobile phone access in accordance with the TD-SCDMA mobile phones to hear the user response, domestic 3G mobile phone voice clear, indicating that TD-SCDMA construction goes well, at least for now have to solve the problem with the 2G interworking. But after the news, TD-SCDMA still only calls within the network.

Alleged use of TD-SCDMA mobile phone users will require the number of daily calls and recorded. And this test will be a period of time, there may be more than 2 months, depends on the specific test progress of the case.

In addition to payment of TD numbers in Beijing than in Qingdao, Baoding and Xiamen will be no more large-scale release, which is after the development of 20,000 user-friendly program to use TD-SCDMA mobile phone part, China Netcom, China Telecom and China Mobile, respectively in the three areas had TD test network. It is reported that these three areas will begin to distribute telephone numbers in the middle of this month. Meanwhile, news that Shanghai will start issuing 3G on the 15th of this month numbers. China-made 3G mobile phone number will be used in paragraph 188.

This will be the last before the TD-SCDMA commercial test, the test results will determine the country's first 3G license issuance time. Minister of Information Industry Wang Xudong, and Reform Commission officials have committed to the 2008 Olympic Games will use 3G communications. Sources said the authorities had planned to debut in late 2006 issued 3G licenses, but because of TD-SCDMA test delay, 3G licenses may be postponed until middle of next year.

If the test smoothly, 3G license issuance is also expected to advance. However, analysts also pointed out, 3G license issuance time not only depends on the TD-SCDMA test results, but also the restructuring of telecommunications operators, and if so, 3G release time may be more delayed.

Enhance the concept of active intrusion prevention IPS is not speculation

Intrusion Detection (IDS), has been put on the market for years, but more and more users find that it can not meet the new network environment for security needs.

IDS can detect passive attacks, and can not take the initiative to stop the threat to the vagaries of the network.

Therefore, it was urgent need to find a proactive intrusion prevention solutions, to ensure that the four enterprise network threat environment in normal operation.

Deep-level defense security needs

Currently, enterprises are facing increasingly complex security problems, security threats are growing rapidly, particularly the risk of blended threats, such as worms, DDoS attacks, spam mail, etc., greatly troubled the user to the enterprise's Wangluo cause serious damage.

So what options do business? Intrusion prevention system is the next generation of security systems business. It not only can be detected, can block the attack before they cause damage to the intrusion detection system to a new level. IPS and IDS obvious difference: intrusion prevention systems block the Code Red, Nimda and SQL Slammer, and the use of intrusion detection systems, users are required after each attack to spend millions of dollars for virus removal. Because of this, companies need the security strategy has not only limited to a single firewall and other protection products, but a deep-level protection strategy.

NAI launched includes host protection IPS technology strategy and network protection strategy for the two most, which is the McAfee Entercept host-based intrusion prevention solutions, technologies and rules of conduct signed by the integrated approach, providing an effective protection as Code Red, Nimda worm that attacks such as; McAfee IntruShield network intrusion prevention solutions, integrated feature library detection, abnormal behavior test, behavioral analysis, correlation, and denial of service techniques that can intelligently detect known attacks, the first place attacks and DDOS attacks, a deep level to effectively protect the enterprise network security.

IPS will replace IDS

Currently, IPS and IDS for the dispute, it was said, IPS, and no new technical breakthrough, but a conceptual speculation, Pubic do not think so. He believes that as technology development and continuous improvement, IPS will replace IDS, NAI IPS technology has been made in a number of international patents, IDS in the network is real-time detection of network attacks, while the IPS includes IDS technology In the IDS based on the increased detection of active response to block the defense function, once the attack is detected, you can take the initiative to cut the intrusion. Of course, true, IDS is already a mature product. Pubic think, IPS will take some time to replace IDS, IPS also requires the user to accept a change process, and now this change is also underway.

Currently, the face of mixed-type attacks, users need a proactive defense strategy, IPS is a large potential market for new business, therefore, NAI technically spent a great deal of input, hope to play a lead role. Now has more than 180 customers worldwide use of IPS products in China, after some users in the test trial of the IPS are also interested. Pubic believe, IPS will have a significant demand for this market, it is very useful to users. IDS products have been used for the user you want to migrate to IPS, you can purchase a license only on the user's input costs are also guaranteed.

It is reported that already has a financial company based on the original IDS, IPS purchased a few licenses to the successful deployment of intrusion protection system IPS.

In addition, IPS is a very technical product, the user's skill level requirements are high, and only on the IPS used properly, the effect will be significant, or just the opposite, but rather as IDS, so, user education and training essential. NAI will intensify efforts in this area, which is the current IPS technologies to promote the great challenges facing.

What is the real IPS

Currently there are many products on the market are dubbed "protection" of the word. But the real intrusion prevention solution should enable companies to analyze can not take measures to protect the system; the same time, it should prevent attacks result in the user's operating system, applications and data corruption. NAI believes that a good intrusion prevention solution should include the following features:

First, the real solution should provide real-time attack prevention and analysis. It should be before the start of any unauthorized activity to identify attacks, and prevent it from access to important server resources.

Second, intrusion detection is the most effective way is to adopt a mixed approach, that integrates specific attack signatures and behavioral rules of power. This hybrid method can provide the protection of known and unknown attacks, while at the same time keeping false positives to a minimum, so do not make any concessions on the loss.

In addition, a strong defense in depth security are based on the concept of protection can be deep. IntruShield's unique architecture integrates a number of patented technologies, including feature detection, anomaly detection and denial of service analysis to be able to multi-gigabit of network traffic and intelligent under the accurate detection and protection. This kind of creative control unprecedented ability of technology to protect those with the most stringent requirements of the network against known attacks to the first occurrence of unknown attacks and DoS attacks.

At the same time, enterprises have to choose whether to adopt the solution of advanced technology industry, is well-tested and used, and are subject to ongoing maintenance, it is very important.

Things correct safety and performance

IDS generally parallel in the network to bypass the network monitor in real-time detection of suspicious traffic, the performance is not significantly affected, but not IPS IDS, it is deployed mainly in the series in the network, all access to the internal network traffic to go through the IPS, if found aggression, to respond immediately to block attacks, so that will affect network performance, NAI also take into account this situation.

NAI's IPS performance is very good, IPS products in more than 20 integrated chip, 60G of cache, to ensure maximum network performance, and this is one of IPS's main selling points.

The so-called "true blue streak", despite the different opinions of the IPS's, but it is the concept of right, and it indeed has been in existence, many manufacturers are successively pushed IPS products, as long as the actual use indeed the role of the user's network security are effective, the user can try.
