SQLServer with its built-in data replication capabilities, powerful management tools, the In

15、ternet is tightly integrated and open system architecture for the majority of users, developers and system integrators to provide a superior platform for the database.Protection of the ten measures of the SQL ServerIn order to improve SQL Server 1 installed security can be implemented ten measures(1

16、) Install the latest service pack.In order to improve server security, the most effective way is to upgrade to SQL Server 2000 Service Pack 3a (SP3a). In addition, you should also install all security updates released.(2) Use the Microsoft Baseline Security Analyzer (MBSA) to assess the security of

17、the server.MBSA is a scan of the unsafe configuration tools, a variety of Microsoft products including SQL Server and Microsoft SQL Server 2000 Desktop Engine (MSDE 2000). It can be run locally, you can also run through the network. Detection tool for the following problem on the SQL Server installa

18、tion: 1) too many members of the sysadmin fixed server role. 2) granted to other roles other than sysadmin to create CmdExec job right. 3) The empty or simple passwords. 4) fragile authentication mode. 5) To grant the Administrators group too many rights. 6) SQL Server data directory incorrect acces

19、s control lists (ACLs). 7) Install the sa password to use plain text file. 8) To grant the guest account too many rights. 9) is also a domain controller system running SQL Server. 10) Everyone (Everyone) group is not properly configured to provide access to specific registry keys. 11) SQL Server ser

20、vice account is not configured correctly. 12) did not install the necessary service packs and security updates.(3) using Windows Authentication Mode.Whenever possible, should requirements in connection to a SQL Server Windows Authentication Mode. From most of the Internet tools against it by limitin

21、g the connection to the Microsoft Windows user and domain user accounts to protect SQL Server, the server will benefit from Windows security enhancement mechanism, such as stronger authentication protocols and mandatory password complexity and expiration time. In addition, the certificate to delegat

22、e (the ability to bridge credentials across multiple servers) can only be used in Windows Authentication Mode. On the client side, Windows Authentication Mode is no longer needed to store the passwords. The stored password is one of the main vulnerabilities of the application using the standard SQL

23、Server login. To install Windows authentication mode in SQL Server Enterprise Manager, follow these steps: 1) Expand the server group. 2) Right-click the server, and then click Properties. 3) in the authentication of the security tab, click the Windows only.Isolate your server and backed up regularl

24、y.Physical and logical isolation formed the basis of the SQL Server security. Should the machine the database resides in a place protected from the physical form, preferably a locked computer room, equipped with flood detection and fire detection / fire protection system. The database should be inst

25、alled in the intranet security zone, do not directly connect to the Internet. Regular backups of all data, and save a copy in a secure off-site location.(5) assign a strong sa password.The sa account should always have a strong password, even in the configuration of the Windows authentication server

26、 so. This will ensure that after the server is configured for mixed mode authentication, does not appear blank or weak sa. To assign the sa password, please follow these steps: 1) Expand the server group, and then expand a server. 2) expand Security, then click Login. 3) In the details pane, right-c

27、lick the SA, and then click Properties. 4) In the Password box, enter a new password.(6) limit the permissions of the SQL Server service.SQL Server 2000 and SQL Server Agent run as Windows services. Each service must be associated with a Windows account security context and derived from this account

28、. SQL Server allows the user sa login (and sometimes also includes other users) to access operating system features. These operating system calls created by the server process account security context. If the server is compromised, then the operating system calls that could be used to attack other r

29、esources, have a process (the SQL Server service account) can be accessed. Therefore, is very important for the SQL Server service is only granted the necessary permissions. Recommended the following settings: 1) the SQL Server Engine / the MSSQLServerIf you have an instance is specified, then they

30、should be named MSSQL $ InstanceName. Run as a Windows domain user account with regular user privileges. Do not run as local system, local administrator or domain administrator account. 2) the SQL Server Agent Service / the SQLServerAgentIf your environment is not required, disable the service; Othe

31、rwise, as a Windows domain user account to run with regular user privileges. Do not run as local system, local administrator or domain administrator account.Important: If one of the following conditions is true, then the SQL Server Agent will need local Windows administrator privileges:SQL Server Ag

32、ent uses the standard SQL Server authentication to connect to SQL Server (not recommended).SQL Server Agent to use a multi-server management server (MSX) account, the account using the standard SQL Server authentication to connect.The SQL Server Agent to run non-Microsoft ActiveX script or CmdExec j

33、obs owned by members of the sysadmin fixed server role.If you need to change the service account associated with SQL Serve r, use the SQL Server Enterprise Manager. Enterprise Manager to set the appropriate permissions for the files and registry keys used by SQL Server. Do not use the Microsoft Mana

34、gement Console service (in the Control Panel) to change these accounts, because it need to manually modulate a large number of registry keys and NTFS file system permissions and enclose tideland for cultivation Windows user permissions.Account information changes will take effect the next time the s

35、ervice starts. If you need to change the SQL Server and SQL Server Agent associated account, then you must use Enterprise Manager to make changes to two services.Disable SQL Server ports on the firewall.The default installation of SQL Server will monitor TCP port 1433 and UDP port 1434. Configure yo

36、ur firewall to filter out data packets reach the port. It should also be on the firewall to block other ports associated with the specified instance.8 using the most secure file system.NTFS file system is most suitable for the installation of SQL Server. Than the FAT file system is more stable and e

37、asier to recover. But it also includes a number of security options, such as file and directory ACL and file encryption (EFS). During the installation process, if the detected NTFS, SQL Server will set the appropriate ACLs on registry keys and files. Should not try to change these permissions.By EFS

38、, database files will be encrypted under the identity of account running SQL Server. Only this account can decrypt these files. If you need to change the account running SQL Server, you must first decrypt the files under the old account, then re-encrypted under the new account.Delete or protect the

39、old installation files.SQL Server Setup files may contain plain text or simple encryption of credentials and other sensitive configuration information recorded during the installation process. These log files are saved location depends on the installed version of SQL Server. In SQL Server 2000, the

40、following documents may be affected: when default installation: Program Files Microsoft SQL Server the MSSQL the Install folder, and specify the instance : Program Files Microsoft SQL Server the MSSQL $ , the Install folder of the sqlstp.log sqlsp.log and setup.issIf the current system is upgrading

41、from SQL Server 7.0 installation from, you should also check the following files:% Windir% folder setup.iss in the Windows Temp folder sqlsp.log.Microsoft has released a free utility The Killpwd, it will find and remove these passwords from your system.10 audit points to the connection to SQL Server

42、.SQL Server can log event information for the review of the system administrator. At least you should record the failure of the SQL Server connection attempt, and regularly view this log. Possible, do not save the log and data files on the same drive. Audit failed to connect to the SQL Server Enterp

43、rise Manager, follow these steps: 1) Expand the server group. 2) Right-click the server, and then click Properties. 3) The audit level in the Security tab, click on failure. 4) For this setting to take effect, you must stop and restart the server.Visual C+ 6.0Visual C + + 6.0, referred to as VC or V

44、C6.0, Microsoft introduced a C + + compiler, the high-level language translation for machine language (low-level languages) program. Visual C + + is a powerful visualization software development tools. 1993 Microsoft introduced the Visual C + +1.0, with its new version come out, the Visual C + + has
