the continuous transaction log backup after the differential database backup. If the log backup is lost or damaged, you must create a database backup or differential database backup and start backing up the transaction log again. Database file or File Group Backup: Definition: a relatively complete backup and restoration process, usually used in super large databases with high availability requirements. Features: Only corrupted files or file groups can be restored without restoring the rest of

Verification data of PHP security knowledge. Your users may be excellent, and most users may use the application as expected. However, as long as the input opportunity is provided, it is very likely that you will be very good at learning your users, and most users may use the application as expected.

The normal user has removed the Root.txt file that is the owner of the administrator (root) and the admin user does not have permission to write (R) . Again, the ability to delete files in the directory depends on whether the user initiating the delete process has write permission to the directory where the deleted files are located. from the experimental results above , it is sa

But in real-world development, we can not hard code user information in the configuration file, usually we are stored in the data. At the same time we shoul

technology, and the recommended switch model is a vswitch of more than 4 series. Dynamic ARP detection Configuration 1) enable Dai on the specified VLAN By default, Dai is not enabled for all VLANs. To enable Dai in a VLAN, run the following command. Switch (config) # ip arp inspection VLAN 10 2) configure the trust Interface After Dai is enabled for a VLAN, all ports belonging to this VLAN are in the untrusted status. to configure a port as a trusted port, run the following command in Port m

Recently, due to the need for work, a tutorial on safety test tool AppScan has been compiled. The directory is as follows:Online for AppScan information is very much, but also very messy very miscellaneous. It is not conducive to systematic learning, which is why I have compiled such a guidebook.In this manual, the following questions are mainly included: What is AppScan? What problem does it solve? Where to download? How to install and hack? I do not want to go into the study, just

A similar problem with a session exposure is conversation injection. This type of attack is based on your Web server's write permissions in addition to the Read permission to the session store directory. Therefore, there is a possibility to write a script that allows other users to add, edit, or delete sessions. The following example shows an HTML form that allows users to easily edit existing session data: The script inject.php executes the

configuration will bring some security issues. I have been using SSH in php cli applications. I used it from cronjobs, but it was not very simple at the beginning. it can be said that it was a great deal of money. The manual on secure use of the Shell2 function is not very practical either. I have conducted many tests before having published this article. I hope you can save some time for configuring PHP after reading this article. In this article, I

3. Updates and patches: the application software and database vulnerabilities used by hacker SQL injection attacks can be found on a regular basis. Therefore, frequent system upgrades and patching are critical. 4. Firewall: consider using the network application software firewall (WAF)-either based on software or application tools, to help users filter malicious data. A good firewall has complete default rule settings. It is easier to add new functio

In asp.net, how does one use an encrypted database to connect strings to ensure data security? When we publish a website, encrypt web. config to effectively ensure the security of database users and passwords. The steps are as follows: 1. Add a key Run: C: \ WINDOWS \ Microsoft.

What filtering does PHP need to make to ensure security for the submitted data? With the simplest user login as an example, $_post[' username '],$_post[' password '], what are the necessary validations to make a SQL query? ------Solution-------------------- At a minimum, you need to escape single quotes to prevent SQL injection, and escape from There are some ready-made functions Htmlspecialchars ($_post[
