**In the information age, with the rapid development of the Internet, everyone has multiple accounts. Many people for convenience, password Settings are basically the same, such a figure will be convenient for the future trouble buried hidden trouble. For information security problems, users must set security passwords according to certain standards or patterns of classification and ensure the independence of important accounts. Cancel the idea of "one set of passwords go everywhere", with distributed security password Settings, will greatly reduce the password leakage caused by "implicate". Data backup and recovery In the data era, the importance of data backup is undeniable. No matter how strict the user's preventive measures are, it can not completely prevent the situation of "high one foot high devil high ten feet high". If accidentally deleted or otherwise attacked, operating systems and applications can be reinstalled, making it difficult to retrieve lost data. Periodic data backup can protect users from some unexpected situations and ensure data integrity and security. Access control With the popularity of smart phones, the convenience of APP is self-evident, and the access obtained by APP use is closely related to the information security of users. In the case of ensuring the normal use of APP, cancel the excess permission information. In addition, the website login account also faces this problem. In order to avoid data security problems caused by website information leakage, users should cancel the associated services authorized by the website, such as "quick login", to control access permissions to a certain extent, and prevent information data leakage. In addition to the user's own efforts in data management.**

## **What is network security?**

**Network security is the practice of protecting critical systems and sensitive information from digital attacks, also known as information technology (IT) security. Cyber security measures are designed to combat threats to networked systems and applications, whether originating internally or externally.**

**The average cost of a data breach in 2020 was $3.86 million globally and $8.64 million in the United States. These costs include the expense of detecting and responding to data breaches, the cost of downtime and lost revenue, as well as the long-term damage to the reputation of the business and its brands. Cybercriminals target customers' personally identifiable information (PII), including names, addresses, identification numbers (for example, social security numbers in the United States, fiscal codes in Italy) and credit card details, and then sell these records on the underground digital market. Leaks of PIIs often result in a loss of customer trust, regulatory fines and even legal action.**

**Complex security systems created by different technologies and a lack of in-house expertise drive up these costs. Companies that have a comprehensive cyber security strategy, managed through best practices, and automated operations using advanced analytics, artificial intelligence (AI) and machine learning are better positioned to combat cyber threats, shorten the life cycle and reduce the impact of data breaches when they occur.**
