Linux learning: CC attack, DDOS attack, SQL injection
What is CC attack? What is a DDOS attack?
CC attacks are mainly used to attack pages, simulating multiple users to continuously access your pages, thereby exhausting your system resources.
DDOS attack, also known as distributed denial-of-service attack in Chinese, refers to the use of server technology to unite multiple computers as an attack platform to launch DDOS attacks on one or more targets.
An attack is to occupy a large amount of network resources through a large number of legitimate requests to achieve the purpose of paralyzing the network.
How to prevent CC attacks and DDOS attacks?
To prevent CC and DDOS attacks, you can only use hardware firewalls to clean traffic and introduce attack traffic into black holes.
For traffic cleaning, you mainly need to buy the anti-attack service from the ISP service provider. The computer room usually has spare traffic
What is website database injection
Due to the uneven level and experience of programmers, most programmers do not judge the legality of user input data when writing code.
The application has security risks. The user can submit a database query code and obtain some data he wants to know based on the results returned by the program. This is the so-called SQL injection.
SQL injection is accessed from the normal WWW port, and on the surface it looks no different from ordinary Web page access. If the administrator does not have the habit of checking logs, the intrusion may not be noticed for a long time.
How to filter and prevent?
If this is injected into the database web page, you can consider using nginx_waf for filtering and prevention.

The five core components of the Linux operating system are: 1. Kernel, 2. System libraries, 3. System tools, 4. System services, 5. File system. These components work together to ensure the stable and efficient operation of the system, and together form a powerful and flexible operating system.

The five core elements of Linux are: 1. Kernel, 2. Command line interface, 3. File system, 4. Package management, 5. Community and open source. Together, these elements define the nature and functionality of Linux.

Linux user management and security can be achieved through the following steps: 1. Create users and groups, using commands such as sudouseradd-m-gdevelopers-s/bin/bashjohn. 2. Bulkly create users and set password policies, using the for loop and chpasswd commands. 3. Check and fix common errors, home directory and shell settings. 4. Implement best practices such as strong cryptographic policies, regular audits and the principle of minimum authority. 5. Optimize performance, use sudo and adjust PAM module configuration. Through these methods, users can be effectively managed and system security can be improved.

The core operations of Linux file system and process management include file system management and process control. 1) File system operations include creating, deleting, copying and moving files or directories, using commands such as mkdir, rmdir, cp and mv. 2) Process management involves starting, monitoring and killing processes, using commands such as ./my_script.sh&, top and kill.

Shell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.

Linux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.

The methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.

The core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.
