巧用Windows命令 拒木马于"千里之外"

      一些基本的命令往往可以识别木马的蛛丝马迹,而且在保护网络安全上起到很大的作用,下面几条命令的作用就非常突出。利用以下命令可以识别木马,远离木马烦扰。   检测网络连接
: c, i7 i7 V' C& t8 R7 ?: s0 L  如果你怀疑自己的计算机上被别人安装了木马,或者是中了病毒,但是手里没有完善的工具来检测是不是真有这样的事情发生,那可以使用 Windows自带的网络命令来看看谁在连接你的计算机。6 R! i* d  U4 F& `
  具体的命令格式是:“netstat -an”这个命令能看到所有和本地计算机建立连接的IP,它包含四个部分——proto(连接方式)、local address(本地连接地址)、foreign address(和本地建立连接的地址)、state(当前端口状态)。) J6 q# |8 R' b6 W9 O1 a3 K
  通过这个命令的详细信息,我们就可以完全监控计算机上的连接,从而达到控制计算机的目的。
9 l# b* r  L! \3 ~9 S0 ^  Y* A  禁用不明服务
# N/ y- }/ z' q* l- I; U  很多朋友在某天系统重新启动后会发现计算机速度变慢了,不管怎么优化都慢,用杀毒软件也查不出问题,这个时候很可能是别人通过入侵你的计算机后给你开放了特别的某种服务,比如IIS信息服务等,这样你的杀毒软件是查不出来的。
- c; r2 {; t6 `) ]& ~; G) T/ k% z( v  但是别急,可以通过“net start”来查看系统中究竟有什么服务在开启,如果发现了不是自己开放的服务,我们就可以有针对性地禁用这个服务了。方法就是直接输入“net start”来查看服务,再用“net stop server”来禁止服务。# g: q9 z& s( M9 B0 ]
  轻松检查账户
& N6 x- e3 ~4 `2 K* i* k+ c  很长一段时间,恶意的攻击者非常喜欢使用克隆账号的方法来控制你的计算机。他们采用的方法就是激活一个系统中的默认账户,但这个账户是不经常用的,然后使用工具把这个账户提升到管理员权限,从表面上看来这个账户还是和原来一样,但是这个克隆的账户却是系统中最大的安全隐患。恶意的攻击者可以通过这个账户任意地控制你的计算机。为了避免这种情况,可以用很简单的方法对账户进行检测。
+ P% S- w/ X' P& x# W  首先在命令行下输入net user,查看计算机上有些什么用户,然后再使用“net user+用户名”查看这个用户是属于什么权限的,一般除了Administrator是administrators组的,其他都不是!% C1 w' X, t% h/ D, ^: A  }
  如果你发现一个系统内置的用户是属于administrators组的,那几乎肯定你被入侵了,而且别人在你的计算机上克隆了账户。快使用“net user 用户名/del”来删掉这个用户吧!

3G mobile phone applications of the times change (B) ... ... with the development of the business model changes

  In June 2006, Motorola NEC, NTT DoCoMo, Samsung Electronics and Vodafone, and other companies started to build a smart phone for the reunification of the Linux platform. In January 2007, the smart phone operating system provider Symbian official in Beijing announced the establishment of the China branch. In the past 3 years, the Chinese market for Symbian has created a global share of 10%. In February 2007, Microsoft announced that South Korean handset maker LG Electronics and Japanese mobile operator Soft Bank to become its Windows Mobile operating system, cell phone customers. ... ... In the global smart phone behind the rapid growth, several major mobile phone operating system, the forces of "one-third of the world," the pattern is rapidly brewing in the new variables. The dramatic changes in the market, will also gradually on the mobile phone application software development and business model have a profound impact.

  Symbian: by providing the flexibility to customize the user interface framework to enable mobile phone manufacturers to introduce a different style interface. To the core Symbian, Nokia has developed S40, S60, S80, and so on a variety of operating systems and applications, to authorize the use of other companies. With many years of accumulation of technology, Symbian smartphones in the area with the highest market share. The main camp of its major vendors including Nokia, Arima, BenQ, Fujitsu, Lenovo, LG, Ericsson, Mitsubishi, Panasonic, Samsung, Sharp, Sony Ericsson and so on. At present, Symbian has set up branch offices in China, is about to launch the industry, specifically for Chinese engineers to develop the institutions of Symbian certification exam, as well as China's Symbian developer community to provide training and support, including the provision of the Chinese developers and materials Local developers, and other activities. A number of independent developers such as China's grand digital red, and so on, has become certified through the Symbian joint development partners.

  Linux: The system is due to the Open Source (open source) features in favor of independent developers to develop high utilization of hardware, powerful mobile applications, and the full realization of low-cost control. Moreover, Linux system will also facilitate enterprise mobile applications and their close connection with the application of a variety of industries, and develop their own security, controlled certification system. Motorola is currently the most important mobile Linux a strong supporter of the (recent reference to the popular A1200 "Ming" smartphone series), the camp also includes NEC, Panasonic, Samsung, NTT DoCoMo, Vodafone and so on. The Linux-based smartphone currently occupy second place market share, making Symbian strong challenger. However, the standardization of mobile Linux has not been a good solution, which will over time lead to Linux-based mobile phone third-party software development is restricted.

  Windows Mobile: the PC operating system monopoly of Microsoft, including Smart Phone and Pocket PC Phone two-level platform. Usually corresponds to the phone hardware (CPU, memory, memory card) high performance strong. Its main camp, including Microsoft, Dopod, Palm, Sony Ericsson, Samsung, HTC, LG, Soft Bank, and so on. At present, most of the vendors are beginning to try to add support for Windows Mobile, and Microsoft Windows Mobile will be as part of its overall corporate strategy, trying to build across the mobile, PC, home appliances, such as the Internet's new multi-platform industrial chain. Windows Mobile is also the current market share is very small, but it does not prevent it from becoming one of the most threatening rivals.

  We can see that some companies (such as LG Electronics) for a variety of platforms have been taken inclusive. In addition to this manufacturer's own wait-and-see factor, also indicates that the petition must show a number of the next operating system have equal shares of common prosperity emerged. RIM, including the Black Berry, the iPhone, Apple Mac OS platform, and other than the closed, nor rule out the possibility that one day China will enter the open door policy and strategy might be.

  At present, Chinese mobile phone software applications to a single treasure chest of K-Java-based games. Follow the development model of its mobile operators to develop value-added business development of the SP standards by the CP (usually phones Game Studios) design and development, to the SP operation, and then through the Treasure Box Monternet platform announced. This is a relatively simple development model, this model can not be denied that laid the cornerstone of the treasure chest of business for the 2.5G mobile value-added services has created tremendous value. However, if the 3G mobile application platform on the environment, it has three problems: First, the developers did not face the end-user demand; Secondly, the developer is not involved in the operation of the product; Third, the development of In the types of products, product features and so on to great limitations. All these problems will greatly limit the 3G mobile phone applications.

  The era of 3G mobile application software development and operations, will be in the following four areas show significant features:

Diversified platform:

  Independent developers (ISV) will no longer be faced only by mobile operators to develop a simple SP value-added business development standards, but to meet the needs of the corresponding development of the smart phone operating system provider of product development norms. In my experience over the Symbian platform game research and development, Nokia and has studied the development of SGR thickness of the dozens of pages of documents (Standard Game Requirement), well aware of the product development of such norms in the complexity of the mobile operators with a simple business norms SP There are several orders of magnitude difference. Once the product development of standards by the operating system provider available, the industry chain is bound to focus on the shift took place, mobile operators and providers of the operating system it will then start the game. For example, to manufacturers such as Nokia's Symbian-based alliance on a global scale has been set up large community of software developers, and the official certification of the Symbian software for the establishment of a threshold issue, at the same time brought together a group of elite partners in development cooperation.

Product transition to the service:

  3G mobile application platform on the CP and SP, it will become increasingly blurred the boundaries between. With the mobile phone software, more and more areas are Online features, traditional stand-alone software development model will be totally subversive, as the original developer of the CP will be increasingly forced to operate into the product to work. This is not just the 3G features, and is also the world's software industry development trend of a unified, that is, from "selling products" to "sell" the change. Taking a panoramic view of the Chinese game industry, in essence, has achieved the first game from the stand-alone products to the online game service changes. In "SaaS" (Software As A Service) driven by the tide, the software itself will be increasingly free of charge, and profit model will gradually shift by service charges. QQ's IM software features are provided free of charge, but the QQ Show, casual games such as the need to pay value-added services, it is an excellent case in point. In this mode, CP and the SP boundaries have disappeared, product development and service providers must assume the same role, and to market directly to end-users in charge.

The inter-network integration:


  The next-generation mobile phone applications and tend to become more PC / Internet application integration, and complement each other to form the symbiotic relationship. Nokia's executive vice president and CTO Outai Luo has said publicly: "The first priority is to embrace the Internet." With the phone's functions by simply gradually communication (Communication) to the terminal complex computing (Computing) terminal change, and the PC / Internet integration will become the trend of the times. We have a little look at recent major high-end mobile phone business of advertising, will find mobile Office suite, mobile MSN / QQ client often become the focus of the eye-catching. Microsoft's Windows Mobile operating system is through with the PC version of Windows and Office suite of highly compatible and rapidly seize market share. Integration of these applications do not even need through mobile operator's network, and only by USB, Bluetooth, infrared or Wi-Fi can be achieved with Internet connections. Nokia has introduced support for the Wi-Fi phone products, and the support of a section of the mobile phone application Skype is also alleged to have come out.

Mixed market segments:

  The era of 3G mobile phone applications is a must for the breakdown of Nagao high (Long Tail) market, therefore the form of software will show a high degree of alienation mixed. As the cell phone privacy, and other characteristics of each end-user will need a high degree of personalized custom software products. Faced with such a chaotic market demand, the traditional top-down management system and software categories will be overwhelmed and collapse, with the need to become agile and software will be provided to create a new market model. For example, users may need a fully integrated Google map and Flickr photo-sharing "mash" services, according to the traditional tree of your software system will be very difficult to be attributed to a particular category. Has been up-and-coming Pica, thumb, and other software are sky is the case. At the same time, high-precision camera, streaming media players, GPS positioning module components, such as the introduction of mobile phones will make the application of increasingly complex patterns, and a high degree of flexibility to integrate a variety of hardware and software resources.

  All of the above changes, in fact, has been in the 2.5G era in the late can see the shape. For example, the recent popular mobile phone software Pica (PICA), met at the same time: support for the smart phone operating system, the development and operation of unity, the Internet and IM interoperability, features a variety of "mix" (instant messaging, VoIP, blog, , ... ...) And so on all the features. Although Pica, and other free services is not in the mobile operator SP supervision, but this is the real market demand driven by the mobile operators themselves have to face this sooner or later.
