program code is written in PHP. But by carefully reading its database table design instructions and related SQL statements, I have thoroughly understood this clever design concept, in this design, the need to delete nodes and pan at the same layer is added (the original article only provides the list and SQL statements for inserting subnodes ).
Below I try to describe this design scheme with a short text, a small number of charts, and related core SQL statements:

Open build service (OBS) is an open and complete software release and development platform. He provides an infrastructure to create software release packages that support a wide range of operating systems and hardware architectures, as well as plug-ins (add-ons) and application images (appliance images) or the entire Linux release package.

Software initialization:before using the device, you must focus on the current configuration or enabled network protocols, which generally require users to provide parameters such as IP address. function Initialization:The Linux kernel provides a range of networking options, and some network options need to be configured separately for each device (such as subsystems that implement QoS), which determine how packets enter the queue and exit queues from the device.

Security researchers have called on Oracle Java 6 users to upgrade to Java 7 as soon as possible to avoid being a victim of active network attackers.
Timo Hirvonen, a senior analyst at F-secure, issued a security warning on Java 6 on Twitter this weekend, called CVE-2013-2463.
PoC for CVE-2013-2463 was released last week, now it's exploited in the wild. No patch for jre6... Uninstall or upgrade to JRE7 update 25.-Timo Hirvonen (@ TimoHirvonen) August 26,201 3

In the pre-defined PCI-DSS analysis of the target CIDR Block, the topology features provide a similar solution, you only need to click to select a network segment and run the analysis report.

Malware killer: zero-day attack
If the operating system is in a completely bug-free environment, limiting user permissions may be a relatively safe method. Unfortunately, the bug does not exist, which provides malware makers with the opportunity to explore new vulnerabilities that have not been patched, such as the notorious "zero-day attack ". The recently discovered OS X Kernel defect also emphasizes this point: Someone can bypass the permission mechanism through this vu
How to Set HTTPS policies for old browsers
A few days ago, a friend asked me: we all said we recommend using the Qualys SSL Labs tool to test SSL security. Why are some of the most powerful Security manufacturers having low scores? I think this problem should be resolved in two aspects:
The situation of domestic user terminals is complex. In many cases, the SSL security configuration is reduced to be compatible with more users;

As the successor of IE browser, Edge browser is more functional and constantly improved. This browser uses a brand new UI and adds various new features. Compared with IE 11, this browser has few vulnerabilities and is highly secure.
