How do databases get hacked?

In this situation which the technology is improving all the people need to progress their knowledge in every field related to technology. If you want to do your works as most straightforward as you want, you need to know about every suitable way for your work. On the other hand, there is a thing with many kinds, and each kind can be used in a specific branch.

In addition to all the introductions that I mentioned first, you need to know "What is the database?"

If I want to explain it vividly, I should say that database is a collection used to gather information about a specific topic. There are many types of databases that I'm going to name them, Distributed database, Personal database, Object-oriented database, Relational database NoSQL database, OLTP  (Transactional Processing Online) database and Graf database.

What are the advantage and disadvantages of databases?

1. For using databases, you need hardware or software, which is high.

2. People usually use one database for all their information, and this isn't right because, with a single problem like the power outage, all the data can be erased.

3. In a company, users always need the information, so when a few people at the same time use that database, it will cause some problems.

What is the usage of databases?

The usage of the database includes a broad field. One of its most essential usages is immediate access to all the information and making decisions easier. Furthermore, it allows decision-makers to decide with more confidence because they don't need to check many different collections.

In databases, you can find Tables and data. Also, there are some things which make the availability faster and easier.

How to set up a database?

To set up a database, we need to pass a few security ways, and one of the most necessary things is choosing a password. That's because people wouldn't access your data quickly, so try not to have an easy password. Also, it would help if you had software too.

What is hacking, and Who wants to hack us?

According to the above  information, databases are essential for their owners to protect against hackers. As you know, when unique or private data fall into the hands of others, it's called a hack. Most of the time, databases are being hacked by the people who need the information for abuse. As an example, they hack the database to extortion of their owners. Without a doubt, the owners of that database give whatever they are keen on to protect their private information.

Also, some hackers don't need our data. Still, they want to use our database to cover their illegal works or enter your database to put some extra information and put you in danger. They can also clean all your data, which can be extremely serious for a company and others.

Furthermore,  some hackers do this just for fun, or it can be gambling between some friends too.

How do datasets get hacked?

In this generation, technology allows us to access everything, even the private and unique information that people try to keep safe and far from other people. Still, for this work which as I have written called hacking, we should know that without doubt for different databases, the hackers should try a variety of ways to access the databases that is because some database owners have high security so the hackers can't hack them quickly or even they can't hack it completely. Hence,  it's good to have a database with high security to be more safe and protected.

Some databases are so vulnerable because they don't have any security. In the beginning, owners didn't make careful about choosing the password and username, so they opened the ways for hackers.

Hackers most of the time, before selecting a database to hack, research its type and security level, then select the one with low security.

1- Try many passwords in a row. Of course, this method doesn't work for databases that use an improved password.

2- When you want to log in like a hacker, you can use malicious codes, including negative numbers, famous letters, and odd numbers.

3- SQL injection: one of the standard ways of hacking is  SQL injection  way that you should identify the weaknesses of the database and find the username and password.

4- Dos and DDoS: This method works with a significant amount of internet traffic.

5- Phishing: owners in this method will receive some messages from hackers, but they think that they are from the website. Most of the time, these messages ask for your loginlogin information.

6- Baiting: It's an old way of hacking. On the other hand, it's the easiest one too.

For this method, hackers leave a device that is often labeled with a fake company or other things. In this situation, some employees plugin that device to their computer, giving the best chance to hackers.

7- XXS(Cross-site Scripting: It's the seventh method, like the fifth. In this way of hacking, hackers use a malicious link, so when a user clicks on it, the information will send to that hacker.

It's one of the most challenging hacking methods that users can't easily fight back.

How can we understand that our database gets hacked?

If we get hacked, we should inform of that, and the way that we understand is to rely on hackers and what they want of our database for instance if they are keen on getting the money they can request money from your friends or family and they send their card number so you can realize.

Totally when your database gets hacked, when you want to log in to the database, don't accept the password, or you will receive some messages which will inform you of hacking.

Hackers can get money from your online account, too. Also, when you get hacked, you will have frequent popups that will open on your screen on every page that you are on, so don't just close them.

Some people use apps to scan your databases and inform you about any illegal login. Also, database owners hire some professional people who have enough knowledge to protect the data and prevent the entry of profiteers.

As you know, there is a variety of antiviruses that help the security of databases be safer.

How can we fight back against hackers?

Now it's time to start the fight back. People get too much nervous when they get hacked, especially when they have necessary and private data that their enemies against them can easily use, so they see themself in real danger. Most of the time, they call the police, and they think it's  the best way to release hackers. Calling the police is suitable for someone who doesn't hurry, but for the specific data, even one minute is late because the hackers won't stop until they get what they want.

In this situation that you get hacked at first, you should calm down. Then if you understand the hacking from massage, you can pay some money, and your database will be safe, but often this way won't work too because the hackers infiltrate deeply.

If you find out the hacking from your password that doesn't look acceptable from your database, you can use the knowledge of the professional person who can help you save your data from the hackers.

But what is the problem with calling the police?

That's because it's the most extended way and you need to go to a police station write your complaint and all about your database after that your complaint is among the thousands of other complaints and as I said in that moment you should choose the best and fastest one.

How do we find the hackers?

Most of the time, no one can find the hackers because their information is fake. They do identity fraud to don't leave any clue because they know the result of this work but some people that hack someone for the first time that most of the time this kind of people do this for fun and gambling among their friends the owners of databases can easily find them for this they can go to the police because they have many photos of hackers maybe the hacker would be familiar for the data owner.

On the other hand, even some professional hackers may be wrong and leave a clue behind them, so you can use another hacker to find them for you.

How do we improve our database security?

1. As I mentioned many times in this article, use an unpredictable password and username.

2. Be a hacker: it means that you put yourself in the shoes of a hacker and try to log in to your database but like a hacker.

3. use a strong backup.

4. Do not use the same password for every page of your database.

5. Be careful about the people who already have the password and want to abuse data.

conclusion

Consequently, we should  pay attention to every single threat  because even the little one can trigger a severe danger, and any carelessness can make us bait for profiteers.
