1、常见的数据库类型包括 微软的SQLServer 、MySql、IBM的DB2、Oracle
2、DBPwAudit数据库密码破解工具
1) 功能:通过挂载字典对目标数据库进行密码暴力猜解,目前支持的数据库包括SQLServer、MySQL、Oracle、DB2
2) DBPwAudit的安装:
图1、上传实验用到的软件包
注释:#crunch 密码字典生成工具
#mysql-cennector-java 密码破解工具需要的驱动(注意:数据库类型不同,,驱动不同)
#dbpwaudit 数据库密码破解主程序
图2、解压dbpwaudit压缩包
[root@attack ~]# unzip dbpwaudit_0_8.zip
3)数据库密码dbpwaudit的使用格式
注意:首先将*.jar驱动复制到 /root/DBPwAudit/jdbc 目录中
DBPwAudit -s
-s - Server name or address. #指定数据库ip地址
-p - Port of database server/instance. #指定数据库服务器端口
-d - Database/Instancename to audit. #指定数据库名
-D - Thealiasof the driver to use (-Lforaliases) #指定数据库类型(Oracle,MySQL,MSSql,DB2)
-U - File containing usernames to guess. #用户字典文件
-P - File containing passwords to guess. #密码字典文件
-L - List driver aliases. #列出所支持的数据库驱动别名
-L
Oracle - oracle.jdbc.driver.OracleDriver
MySQL - com.mysql.jdbc.Driver
MSSql - com.microsoft.sqlserver.jdbc.SQLServerDriver
DB2 - com.ibm.db2.jcc.DB2Driver
4)使用方法1、破解SQLServer数据库
#./dbpwaudit.sh -s IP -d master(数据库名) -D mssql(数据库类型) -U username(字典) -P password(字典)
使用方法2、破解MySql数据库
#./dbpwaudit.sh -s IP -d mysql(数据库名称) -D MySQL(数据库类型) -U username(字典) -P password(字典)
注意:驱动是需要手动导入的。需要创建自己破解字典
5)、解压mysql数据库驱动软件包
[root@attack ~]# tar -zxvf mysql-connector-java-5.1.24.tar.gz
6)、手动将驱动*.jar复制到 “jdbc”目录中
[root@attack ~]# cp mysql-connector-java-5.1.24/mysql-connector-java-5.1.24-bin.jar DBPwAudit/jdbc/
3、crunch生成密码字典文件
1)、crunch用途:字典生成工具
2)、工具特点:
· 使用排列组合的方式生成字典文件
· 可以通过行数或文件的大小中断生成过程
· 支持生成数字和符号结合的字典文件
· 支持区分大小写字母
· 当生成多个文件时增加一个状态报告
3)、工具更多信息及下载:
4)、crunch工具的安装
图1、解压crunch工具的压缩包
[root@attack ~]# tar -xvf crunch-3.4.tgz
图2、make编译
[root@attack ~]# cd crunch-3.4
[root@localhost crunch-3.4]# make
Building binary...
/usr/bin/gcc -pthread -Wall -pedantic -std=c99 crunch.c -lm -o crunch
图3、make install安装
[root@localhost crunch-3.4]# make install
5)、crunch使用格式
目录:/pentest/passwords/crunch/
用法1:#./crunch 密码最短位数 最大位数 密码的可能性 -o 生成密码字典
#./crunch 5 5 1234567890 -o pass1.dic
用法2:#./crunch 最短位数 最大位数 charset.lst(策略集) 使用的策略 -o 生成密码字典
#./crunch 6 8 charset.lst mixalpha-numeric-all-space -o pass2.dic

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
