Although only a handful of Linux viruses, but based buffer overflow (Buffer Overflow) vulnerability to attack or surprise for many Linux users.The so-called "world's first Linux virus"?? Reman, strictly speaking, not really a virus, it is essentially an old, in the Linux / Unix (also includes Windows and other systems) already exist in the world, the "buffer overflow"attack program.reman is just a very ordinary, automated buffer overflow procedure, but even so, in the Linux world has caused great alarm.

For some time, a lot of advertising and media reports have referred to the "active defense" concept.What is "active safety"?Different manufacturers have different interpretations, there is no uniform standard.For example, Cisco and Huawei will be provided from the network level, while Microsoft is put on the defensive from the terminal.But one thing is certain: The reason why suddenly made active safety, because the user bought a lot of security products, including anti-virus software, firewalls and intrusion detection products, we found that there is still a variety of security risks.At this time, people have to think whether there are active safety technology to quickly respond to various security risks?

Microsoft on the Windows Firewall issue a warning to the user, an attacker could exploit the vulnerability, which is also the one hand, they attack the system.Microsoft said the problem is in fact means that the Windows firewall can hide specific information, it is difficult as they should be.

Online shopping, online games, chat, if you are a network of people, most worry about is the computer poisoning, so you can enjoy smooth network brings convenient, exciting and fun.Now, you only need to come up 3 cents a day, order KILL stand-alone anti-virus software will be able to enjoy safe and nontoxic in the network world.

You have determined to make great efforts to improve application security?

Vulnerability Overview
========
Microsoft Windows manufacturers in the July 16, 2003 issued a number MS03-026 security vulnerability (for details, see http://www.microsoft.com/technet/security/bulletin/MS03-026.asp), a statement asWindows NT, Windows 2000, Windows XP and Windows 2003 system has security flaws RPC, will lead to unauthorized users through the system privilege user (SYSTEM) to achieve code execution, it can direct that a hacker

First, the use of two interfaces to meet different needs

Vista firewall has two separate graphical configuration interface: First, the basic configuration interface, you can "Security Center" and "Control Panel" to access; second, advanced configuration interface, users create a custom MMC, can be used as plug-insto visit.

Following the October 14 Jiangmin Science and Technology launched the first anti-virus "sandbox", "Cloud security" anti-virus system, recently, Rising, Kingsoft has a high profile launch of "Cloud security" concept, and launched a "cloud security" as the highlight of the 2009version.So far, the three major anti-virus vendors have a "cloud security" system, and to rely on the system to effectively deal with the current rapid growth of new viruses and Internet threats.

With the development of high-tech products in the company of a firewall is increasingly common, but what the firewall and home office related link?In practice, firewalls are generally optional VPN module (Note: VPN, Virtual Private Networks, is authorized by the communication between the two sides to establish the safety of the public communication line consisting of the tunnel, the tunnel communication data is encrypted in the securitytransmission, for the government, enterprises, headquarters and branch offices within the cluster , can provide users with high-speed, secure, reliable, manageable, high-quality services.) VPN confidentiality and has a large low-costunderstanding and recognition of the majority, but not less frequently used now.Here, I will take the company's firewall Amaranten example, briefly introduce this feature.

Firefox26 at just the security upgrade to 2.0.0.2, it was soon discovered another very dangerous security flaw, and Mozilla has been officially confirmed.

November 23, IE7 and then exposed 0day vulnerabilities, Jinshan network shield to intercept the first time, and provide solutions to inform the user.In the meantime, as a security company, has not found the 360 loophole, but also published an article Jinshan false slander, and in the Microsoft official acknowledged that the vulnerability exists, the 360 continued to publish inaccurate articles attacking Jinshan, 360 such serious distortionsthe fact that right and wrong acts, not only to the user in a timely manner to prevent problems caused by the vulnerability, but also on Kingsoft's reputation caused serious violations, for which the following statement Jinshan again:

Many users send and receive mail with Foxmail, often using their own accounts on the encryption method to protect the privacy of messages.As everyone knows, the Foxmail own shortcomings, just encrypt the account, your mail is not any privacy safeguards.Others just a few simple steps can the privacy of your glance.So how to reinforce your Foxmail? Here to Check it out together.

Java Server Page (JSP) technology for building dynamic web pages are constantly heating up.JSP and ASP, PHP, not the same working mechanism.In general, JSP pages are compiled in the execution-style, rather than explain the style.The first call to execute a JSP file is compiled to Servlet process.When a browser requests to the server that a JSP file, the server checks since the last compiled JSP file does not change, if not changed to direct the implementation of Servlet, without having to recompile, so they will have a significantly improved efficiency.

Port wireless network coverage exists in the radio range of a space among the wireless network security is very important to the AP Digital has a perfect security solution.In addition to using encryption means to prevent malicious attacks, SSID hiding is also very simple and efficient.SSID is the name of the wireless service area, the equivalent of IP addresses, usually broadcast SSID is published to facilitate the use of network users, but if we hide the SSID, then only he had known the SSID to connect to the specified user does not know the SSIDThe other non-specified user can not connected to the wireless network, as hackers do not know if our IP address, there is no way for us to attack the same.In addition, DCWL-3000AP also features MAC address filtering, you can limit the computer to determine the company into the wireless network connection, and refused all other computer networking
