This method has a certain probability that there will be repetition
2. PHP built-in function uniqid ()
The Uniqid () function generates a unique ID based on the current time in microseconds.

Snort is an IDs (intrusion detection System) software developed by the U.S. Sourcefire Company under the GPL v2
Snort has three modes of operation: sniffer, packet recorder, network intrusion detection system mode. The sniffer mode simply reads the packet from the network and displays it as a continuous stream on the terminal. The packet logger mode logs the packet to the hard disk. Network intrusion detection mode analyzes the data stream in order t

In the days when the network is booming, network security issues have become increasingly prominent. Black and white channels on the network are fiercely competitive in various fields of network security. The Black Hat community is constantly introducing new technologies to avoid or bypass Network Intrusion Detection Systems (NIDS). NIDS developers are constantly adding Detection techniques to their own products.
However, due to the limitations of NIDS, the day of victory is leaning towards the
NIDs uses the original network information as the data source, uses the network adapter running in the random mode to monitor and analyze all the communication through the network, collects the relevant information and logs it, while HIDs is usually installed on the detected host and connects with the host's network in real time. Responsible for the intelligent analysis and judgment of the system audit log. If an illegal intrusion or violation of statistical laws is found,
From the reality, the prices of the popular IDS products in the market range from 100,000 to millions. This relatively expensive cheese is widely criticized and the result is: generally, small and medium-sized enterprises do not have the ability to implement IDS products. They focus on the reinforcement of routers, firewalls, and switches above Layer 3. Although many large and medium-sized enterprises alrea
Snort has always been the leader of network intrusion Detection (IDS) and intrusion prevention tools (IPS) and, as the open source community continues to evolve, Sourcefire for its parent company (for years, Sourcefire offers a full-featured commercial version of vendor support and instant updates snort , while still offering a limited free version of Snort for free, snort is likely to continue to maintain its leadership position with continuous suppo

To effectively capture intrusion, IDS must have a strong database of intrusion characteristics, just as the public security department must have a sound criminal information base. However, IDs generally with the characteristics of the database are more rigid, encounter "face-changing" intrusion behavior often meet not acquaintance. Therefore, it is necessary for the administrator to learn how to create a ch
Intrusion detection is considered to be the second security gate behind the firewall, which can monitor the network effectively without affecting the network performance. However, for a long time, the problem of "false report" and "false positives" of IDs has been bothering users. In this respect, the East soft Neteye IDs from "Application First", in the full range of products strictly implement this idea,

Questions raised:
Intrusion Detection (IDS) is a special security device that is used to discover hacker intrusion. Early in the time is very simple, is a log analyzer, like a needle in the log to extract the hacker's visit records; Later, the hacker learned to be good, before leaving their own "stain" record all erased; The record is gone, log analysis is hard to find hackers Of course, some novice hackers do not have this awareness and ability. Now
In the document management system of the moss2007 era, a unique identifier (unique identifier) is required to effectively manage our documents. However, such a unique number was not provided at the time, and many users or developers had to find another way to achieve this requirement. Of course, in the previous moss2007, the system can use URLs to locate documents, but the main problem is that when you delete or move a document, the previous URL of the document becomes invalid. If you share a do
At the beginning, hackers generally evade IDS monitoring by sharding IP packets. Many IDS systems do not have fragments.Reorganization capability. Therefore, these IDS systems cannot identify attacks using the sharding technology. If your NIDS system cannot be brokenSlice restructuring.
