complete.Utilization of redundant fieldsThe use of redundant fields is actually just for the convenience of developing a tip.A small example can be seen in detail. A loan has to be approved by many people. So there is a table of borrowing and approving processes , and a couple of them. Through the borrowing number can go to the audit table to check all of its audit status.At this point, I choose to deposit the Audit process table ID (foreign key) in the borrowing table, and save the current aud

Prevent Ctrip from happening againFirst explain the database firewall principle (white list mechanism): Similar to 360 mobile phone defender, pre-defined address book, others call you, only in the Address Book phone can answer, no direct rejection in the Address book.The database is usually the focus of sensitive information, but also one of the biggest targets of hacker attacks, after the
Label:In a phase, two stage, some students, for SQL statements always use the concatenation of strings, this is a bad problem, this greatly affects the security of our program, so we generally recommend preprocessing mode, for this mode of students do not want to learn to study hard, I would like to introduce another way to prevent SQL injection, I hope to help you! It should be said that even if you do not deal with the special characters of HTML or JavaScript, there is no disastrous consequenc
To tell you the truth, the installation process really went through about one months, and has been procrastinating until last night before the official installation is complete. It was supposed to be April when the plan to install SQL Server 2008, but due to some reasons for the system has not been installed successfully, but also from the Internet to find a breach and ask my brother, together on the Internet chat about the installation environment of
problems encountered in the experiment to answer questions and analysis, let students communicate independently and so on.Through a semester of study, I think I myself for Linux is only a few of the fur, about this operating system a lot of knowledge I do not understand. Linux is a very intelligent system, but at the same time it has a lot of system vulnerabilities, such as Set-uid, it is an important security mechanism. When a set-uid program is run, it is assumed to have the owner's permissio
the class to perform other duties. This coupling can lead to fragile designs that can be compromised when changes occur.For example, I often see some Android development in the activity to write bean files, network data processing, if there is a list of adapter also written in the activity, asked them why in addition to find out there is no reason to split them into other classes is not more easy to find, If the activity is too bloated, it is obviously not a good thing, if we want to modify the
time, which makes string a special class.The benefits of the non-variability of the string class1. String pooling is possible only if the string is immutable. The implementation of a string pool can save a lot of heap space at run time, because different string variables point to the same string in the pool. But if the string is mutable, then string interning will not be implemented (translator Note: string interning refers to just one save for different strings, that is, not many of the same s
property.Using the Request_firmware interface allows you to publish device firmware with your driver. When properly integrated into the hot-swap mechanism, the firmware loading subsystem allows the device to streamline its work "outside the box" Obviously this is the best way to deal with the problem.However, let us ask one more warning: The device firmware does not have to be published without the manufacturer's license. Many manufacturers agree to license their firmware under reasonable terms
PCI (here, PCI-DSS, payment card Industry data security standards), We call this a hybrid implementation pattern. The solution is to use a combination of virtual LANs, firewalls, intrusion detection/intrusion prevention systems (IDS/IPS) to ensure virtual machine isolation to support hybrid implementation patterns. Data classification and policy-based management, such as DLP data breach protection, can also be used to prevent data clutter. In a cloud

All at the time of defining classes, interfaces, methods. After the definition is finished, think about it, there is no more than one motive to change this class, interface, method. If the answer is yes, the description defines the class, interface, and method with more than one responsibility

In addition to still unable to protect the data, the password itself caused a lot of trouble.
Too easy to be broken, too difficult and easy to forget. One thing that explains the problem is that there are services that specialize in password management, such as LastPass and 1Password, that generate random, complex passwords and save them for you. But LastPass's two-time
Microsoft attaches great importance to the operating system of Windows 8, a few days before the burst will likely cause a hardware-level breach of the vulnerability.
