Discussion on Oracle Password Security and Protection Strategies

Oracle database has always been one of the most widely used database management systems in enterprises because it is powerful, stable and feature-rich. However, against the backdrop of growing cyber threats and data breaches, ensuring the security of information in databases has become even more important. Oracle database password security and protection strategies are a key part of ensuring database security. In this article, we will explore the importance of Oracle password security and propose some protection strategies, along with some concrete code examples.

The importance of password security

Password is the user's access credential to the database and is the first line of defense to protect the security of information in the database. Simple and weak passwords can be easily cracked, causing sensitive data to be leaked or tampered with. Therefore, it is crucial to ensure the security of passwords.

Password security protection strategy

1. Complexity requirements: Password must contain letters, numbers and special characters, and be no less than 8 characters in length.
2. Regular change: Regular password change is an effective preventive measure. It is recommended to change it every 3-6 months.
3. Password history: Do not allow the use of several recently used passwords to prevent users from frequently changing back to their original simple passwords.
4. Account lock: After multiple consecutive failed login attempts, the account will be automatically locked to avoid brute force cracking.
5. Limit the number of login attempts: Limit the number of login attempts to prevent brute force cracking.
6. Monitor password encryption: Protect the security of password transmission through SSL and other encryption methods.
7. Encrypted storage: Encrypt and store passwords to avoid plain text storage.

Specific code examples

Modify user password

ALTER USER 用户名 IDENTIFIED BY 新密码;

Set password expiration time

ALTER PROFILE default LIMIT PASSWORD_LIFE_TIME 90;

Set password complexity requirements

ALTER PROFILE default LIMIT PASSWORD_VERIFY_FUNCTION verify_function_name;

Lock User Account

ALTER USER 用户名 ACCOUNT LOCK;

Summary

Protecting password security in the Oracle database is an important part of ensuring the overall security of the database. Adopting a series of password security protection strategies, combined with specific code examples, can improve the security of the database and avoid information leakage and loss. When enterprises manage Oracle databases, they must pay attention to password security issues and strengthen password management and protection measures.
