A breach of security data is where critical data and sensitive information Is obtained without the knowledge and authorization off the owner’s system. Data is so valuable nowadays and if the attacker pulls off a data security breach that means the attacker could have innocent people’s private information, account details, Finances. The attacker could even modify or alter or even destroy any sensitive data once the data security breach has been successful. The attacker could also steal private information and account details for fraudulent use, make an account on the information the attacker has obtained.

Data security breaches are becoming more frequent, and it is important to know how these threats occur. There are a few things to look out for to be less exposed for data security breach :
