to ensure that the standards defined in the application. There are mainly white list and blacklist two methods to achieve. In theory, the whitelist is more secure than the blacklist because it allows only the data defined in the whitelist to pass, and all other data is filtered out. The blacklist only filters data that is defined in the

Below we as the manager of the identity, from the perspective of defense to talk about SQL anti-injection.Through the principle of SQL injection we learned that to successfully exploit SQL injection vulnerabilities, we need to meet two conditions, one is that the attacker can control the user's input, and the injected code is executed successfully. The following content is mainly about these two aspects to unfold.First, we need to han

I installed Ubuntu today but found that I cannot access the Internet. I started to troubleshoot the problem:
1. First, check whether the network connection is correct and whether the network cable used works properly.
2. Check whether the network card works properly. The detection method is as follows:
A. Ping 127.0.0.1
B. Ping the static gateway address
C. Ping the Host Name (hostname indicates the host name)
3. Check whether the NIC address is correctly configured. (The ifconfig co

This program is just the simplest example. We will add many judgments to the actual code implementation. For example, we may want to exclude the IP address segment of the whitelist and allow s

Many ADSL Modem systems are integrated with the firewall function to protect users' systems from DoS attacks and malicious attacks from the LAN. You can also set to monitor attacks and notify users in the form of E-mail if any problem is found. If your LAN is shared with the Internet through the ADSL Modem, enabling its Firewall is a good choice, although its functions are not as powerful as professional firewalls, but it is a "free lunch" after all ".

In ubuntu 10.04, if it is a ralink wireless network adapter, it may be connected to a wireless network that is not encrypted or TKIP, but cannot be connected to a CCMP wireless network. This is because the system's built-in rt2870sta driver has a bug. The system comes with the 2870sta and 3070sta drivers, so there are conflicts during loading. Therefore, you need to add other unused blacklist drivers or simply delete them directly, however, the origin
