Data security is a fundamental concern of all computer users. Most computers allow a user to create a password-protected account, but there are more ways to protect your data. Disk encryption is one way to keep your data safe, and then there are many backup solutions, both free and paid, that can keep a copy of your important data in case of loss.

WHAT TASKS does dbms do?
A Database Management System or DBMS provides the interface between users and a database. Some of its tasks include: data integrity, security, recovery of data, support concurrent updates and update data.
Difference between database integrity and database security?
Integrity is related to trust in terms of the data. We need to be sure that the data is being retrieved accurately. Particularly when there are multiple tables that are linked to each other, we need to be sure we can trust those links so that data can be selected from linked databases. This is all about database integrity. Database security is making sure the database is safe. Different people may have different levels of access and some people should have no access at all. Things like passwords and other security measures will do this. Some users may be allowed to see data, but not change it. Some users may only be able to see some data that is relevant to what they need to do, but not have access to other data. So for example, in a company only the people that work in the wages department will have access to that data and the ability to change it. People in other department would not be able to do that. That is all part of database security.
Who needs cyber security?
Everyone who uses an Internet-connected device requires some form of cyber security to protect their device and the information stored on it from harm, such as viruses, malware, or hackers attempting to steal your data.
How can password help in data security?
If it is a good password, then it can help a great deal. Depending on the length and complexity of the password, it can take an attacker months, if not years on a super computer to crack a challenging password. There is no such thing as a completely secure system, but having a good password can certainly stall an attack for some time.
