Data Breaches and How to Prevent Them
A data breach is a broad term that can apply in a few different circumstances. In general, it refers to where someone gains unauthorized access to your data to use it maliciously. Here’s some information about data breaches, including how dangerous they are, and what you can do to prevent them.
An Overview of a Data Breach
Usually, when someone commits a data breach against your company, it is to steal your information. They do so for two main reasons:
To Sell It
An individual or group of people who perform a data breach against your systems are usually looking to get paid. They can sell information hidden in your account to many different people. For example, they are looking for your user’s passwords so that they can breach their accounts on other websites.
They might be after your user’s credit card information. If they successfully obtain this information, they can either use the cards to make fraudulent purchases themselves, or they can sell the information to a third party who will then do this themselves.
There is certainly a black market out there for stolen information of all kinds. This information could be-
- Anything else you can imagine.
Hackers performing data breaches could be after data from government sites, company servers, hotels, or just about anywhere else. Anywhere they can obtain information, including proprietary information, that has some value to it will be where they go.
To Brag or to Warn
Some groups just break into systems to show off that they can. Groups like Anonymous sometimes do this. If they don’t like a website for some reason, they might make changes to a site to show that they were inside their systems. They might steal information that isn’t that important just to show that they can, especially if they don’t like you for whatever reason.
Some groups are after information for political reasons, or they are after a breach just to warn organizations to alter their behavior.
Who Should Worry About a Data Breach?
Just about any company that runs a business online has a cause to worry.
- Hotel Companies- An attacker would look for customer details like credit card information, which could ruin the hotel’s reputation completely. They might also try to obtain embarrassing photos or other information to sell or to blackmail you directly.
- Software Companies- A bad actor here would be after any kind of sensitive project information that a software company has. Selling these secrets to the competition could be very lucrative for someone committing a breach. They can look through emails and passwords this way as well, to find even more sensitive information, or just to sell to others who might want it.
- Anyone-The various methods of causing a data breach could potentially victimize anyone. This includes using Server Side attacks, Xss, RFL, SQL injections, DDoS to distract while using another method, backdoors, and vulnerabilities in Windows or other programs, and so on. There are about as many potential methods of data breaches as there are numbers of people who try to pull one off.
How Do Breaches Happen?
First, a criminal analyzes a company for weaknesses. This could be individual people, it could be the system at large, or it could be the network. Then, they start to attack the weakness. This could be a social attack on an individual or something like a “brute force” attack on a network.
Network vs. Social Attacks
Network attacks are caused by criminals that use weaknesses within the system itself, applications, or infrastructure. In contrast, a social attack targets employees directly by tricking them into granting access to the criminal. This can happen through a type of attack called “phishing” for example, where a hacker sends a link to an employee that makes it look like they are connecting to a company site to log in.
Instead, it is a fake site that collects the employee’s login information that the hacker can then use to breach the network to gain access to sensitive data.
In other situations, a social attack can trick an employee into running a malicious program on a computer system that gives the hacker access to systems that they shouldn’t have access to in general. In many cases, all they have to do is gain access to one computer and then they can use this to get deeper into a company and get the sensitive data they want. After that, they can go on their way and sell the data to whoever they want.
Data Breach Causes
Some data breaches are highly preventable and happen for a reason related to someone making a mistake. Examples of this include:
It only takes a single breach on a single computer or account for a hacker to have a successful breach and get into a company’s systems. If just one employee has a password that’s easy to guess or brute force by using a program to guess many passwords at once, then the breach could happen just because of that.
Failure to Update
If an employee isn’t updating their computer constantly, then a hacker can often gain access this way since the updates are often covering known system vulnerabilities that were just discovered.
Protecting Yourself from Data Breaches
Ultimately, you need a combination of good internal practices and help from IT companies who know what they’re doing to prevent damaging breaches from happening. Teaching employees to not open suspicious emails is a big part of it, for example.
Having strong antivirus programs is also important.
However, ultimately many breaches are only preventable if you have an IT company to help protect you from more sophisticated kinds of attacks.
