What is the first guarantee of database security?

#The first guarantee of database security is the security of the network system.                                                                                                                                                                                           (Recommended learning: phpstorm)

Due to the diversity of connection forms, uneven terminal distribution, openness and interconnectivity of the network, computer networks have the characteristics of This leaves the network vulnerable to hackers, geeks, malware and other malicious attacks. In order to prevent and avoid attacks and intrusions and ensure the security of online information, network security systems play a big role.

There are currently three types of common network security systems that are widely used - firewalls, IDS (network intrusion detection systems), and IPS (intrusion prevention systems).

Firewall

Firewall is the most mature network security technology and the most common network security product on the market. It is a very effective method on the Internet. Cyber ​​security tools.

It mainly protects the information and structure of the internal network by shielding it from the outside world. It is a barrier set up between the internal trusted network and the external untrusted network. It can control the flow of information into the trusted network by implementing a relatively broad security policy to prevent unpredictable potential intrusions and damage. It can also limit the trusted network Unauthorized access to external networks by users in the network also weakens the functionality of the network.

Network Intrusion Detection System)

IDS is a new generation of security technology following traditional security protection methods such as “firewall” and “information encryption”. Intrusion detection technology is a technology designed and configured to ensure the security of computer systems and can promptly detect and report unauthorized or abnormal phenomena in the system.

It collects information from several key points in a computer network or computer system and analyzes it to discover whether there are any violations of security policies and signs of attack in the network or system.

IDS is generally located at the entrance of the intranet and installed behind the firewall. It is used to detect intrusions and illegal activities of internal users, and provides real-time protection against internal attacks, external attacks and misoperations. When the network system is subject to Interception and intrusion processing before harm occurs. It can monitor the network without affecting network performance, thereby protecting the network.

IPS (Intrusion Prevention System)

IPS is an active, intelligent intrusion detection, prevention, and prevention system. It can not only detect the occurrence of intrusions, but also It is an intelligent security product that can terminate the occurrence and development of intrusion behavior in real time through a certain response method, and protect the information system from substantive attacks in real time.

IPS can not only detect attacks, but also effectively block attacks. It provides in-depth protection and focuses on active defense. It can be said that IPS is a new network security product based on IDS and built on the development of IDS.
