Requirements for document protection downloads
If we need to sell digital forms of goods on the site, such as electronic books, digital oil painting, and so on, how to prevent unauthorized users from illegally downloading your product while it is available for authorized users to download normally? Through forms authentication, this problem can only be partially resolved. In this article, I'll explain how to prevent some users from accessing certain files on the site, even if they can be browse
Incidents – Security vulnerabilities penetrate user desktops
In February 2009, Microsoft released a widely-watched ms09-002 security vulnerability Bulletin and immediately updated patches for the vulnerability. When a visitor accesses a page of a particular specification using an IE 7 browser, the MS09-002 vulnerability can allow remote malicious code execution to disrupt the visitor's computer system. The typical problem is that browser-oriented malicious attacks have become the most rapidly g
1. Overall focus
It is usually not enough to observe the system energy, it is necessary to take account of the whole systems such as disk/controller, CPU, network usage.
2. Operating System Tools: Sar,vmstat,iostat, etc.
UNIX vendors offer a variety of system monitoring utilities, including ordinary command-line utilities such as Sar,vmstat,iostat, and many vendors provide graphical tools such as HP's Gl

• Prepare the business unit to adopt cloud computing. Even if the IT department cannot justify the use of cloud computing, your business unit will be able to prove it. Cloud computing is a tempting business. The infrastructure of cloud computing can be configured with a credit card, and the entry and exit thresholds are low. Don't stop these efforts, learn from them.

Although it is very professional, it is always difficult to reach the level of professional vendors at the application layer. Therefore, if you select a digital manufacturer, because the system is closed, the user must make all the products of the digital manufacturer uns

1. Overview of Intranet Security
After the 21st century, with the rapid increase of information technology in China, the Intranet Information security has received more and more attention. In just a few years, Intranet security products and vendors have emerged. However, it is worrying that although many products and vendors provide services with the concept of Intranet security, the actual technology and c
intercepted before the arrival of the virus. Generally, the security technology of personal computers is that the antivirus software can be eliminated only after the virus occurs. Even if the antivirus software is not upgraded, it cannot be effectively protected.
Therefore, the cloud security technology idea is to use cloud servers to instantly collect a large amount of virus database information, and timely and effectively protect the user's local end, so as to achieve the purpose of sharing

The first proposal for the new HTML Version comes from a W3C Working Group. The idea of this working group is centered on the XHTML 2-standard, continuing the development direction for further purifying XHTML and returning to the first version of HTML design concept.
Some important HTML experts outside W3C-browser vendors, Web developers, authors, and other related personnel-disagree with th
) vro products of many manufacturers, such as Linksys and Netgear, have backdoors. Hackers can directly control the vro and initiate DNS (Domain Name System) hijacking, information theft, phishing, and other attacks, directly threatening users' online transactions and Data Storage Security, turning related products into security "mines" that can be detonated at any time ". Taking some router products in D-LINK as an example, attackers can obtain full control of the router by using the backdoor.
Virus and Anti-Virus products are born enemies. Due to the endless existence of viruses, this field of Anti-Virus products will naturally be divided by many vendors, as a result, multiple Anti-Virus engine technologies have been developed.
The Anti-Virus engine is the key to determining whether the anti-virus software technology is mature and reliable. What is the Anti-Virus engine? In short, it is a set of technical mechanisms to determine whether a
Anti-Virus Software for Web Security Products
As an important security application tool, anti-virus software has always been favored by users. As the saying goes, anti-virus software will continue to improve the detection and removal technology and operating mechanism with the variants and proliferation of various viruses.
In recent years, the anti-virus software market has become increasingly competitive. domestic manufacturers have also paid more attention to product technology innovation and
As a programmer, there are various technical trends that coexist and are gradually replaced. For example, HTML5 will replace Flash and Android will occupy half of mobile development. So how can programmers choose advantageous technologies, so as not to be eliminated in the tide of technology has become a top priority, today to the majority of programmers to introduce some of the technology that must be understood and how to look at these technology trends from the whole.Viewpoint 1: HTML5 is a t

In addition, Windows 10 has more vulnerability defense and mitigation measures. For example, Windows 10 Kernel Object Manager adds cookies in the kernel object header to prevent kernel pool overflow attacks in the DKOM mode.

In addition to timely patch updates, operating system vendors, security
Emergence of active defense
In recent years, people have evolved from medical treatment to regular health check and prevention. The concept of security threat defense in the information security field is also changing. "Pattern" identifies viruses as the main technical means of anti-virus software, but this method can only serve as a final solution-only after a piece of code has been compiled can we determine whether the code is virus, to detect or clear the virus. Antivirus software

Dbbs, also known as dbbs, is the abbreviation of database baby sitter. Junior DBAs often work part-time, and they are programmers or other jobs at the same time. Junior DBAs often write their resumes well and participate in many database-related projects or jobs. However, these projects or jobs are often: third-party software vendors have installed and configured databases, and they only
