7 types of data breaches and how to prevent them – Enterprise Podcast Network

We live in the information age. The personal data of all of us is stored in databases and servers around the world. Large-scale corporations, the companies we work with and the companies we are registered with have valuable personal data, and we trust them to protect it at all costs.

But the fact is that data breaches happen all the time. Even with the best protections in place, malicious actors continually seek to infiltrate and steal your data. And the way cybercriminals do it, and the volume they try to do it, just keeps going up.

It is important, especially if it is a company that has none amount of data about subjects (even as tiny as an email address), that you know about these seven types of data breaches and how to prevent them. As a well established and experienced company providing IT support in London For customers of all shapes and sizes, we want to help you stay on top of these malicious actors and protect the valuable data you have about your employees and data subjects so you can avoid potentially massive financial penalties and business operations consequences. .

1. Unauthorized access

A breach is unauthorized access by definition. But this is a particular scenario that most of us imagine when we think of a data breach.

A skilled cybercriminal can gain unauthorized access through a variety of avenues, by navigating firewalls and other defense systems, or by exploiting access databases. Some of the most common methods for cybercriminals to gain unauthorized access are through phishing, spyware, and other techniques they can use to gain access to private networks.

Often these common types of unauthorized access occur due to human error. This is especially true of phishing and spyware attacks, as those who know the signs can easily spot and avoid them. The best way to prevent unauthorized access in this way is employee training. You can hire professional IT support services that can provide employee awareness training to help prevent the most common cyberattacks and prevent breaches before they have a chance to take hold.

two. ransomware attacks

The incidence of ransomware attacks has been on the rise for some time, and they can be particularly devastating.

Ransomware attacks crash a computer system. The hacker then demands a ransom to release the valuable data they have held. The first signs of a ransomware attack are not being able to access data or files and being notified of the need to make a payment (ransom hold) to have the data released.

The key to preventing ransomware attacks is to not let hackers sneak a peek. Only click on known and trusted links. Never visit untrustworthy websites (especially if you don’t have good anti-malware installed). Do not reveal personal information. Keep your systems and software up to date. And always use a VPN on public Wi-Fi networks when working remotely.

3. accidental exposure

The inconvenient reality is that most of the Internet is used with malicious or malicious intent, and the number of data breaches that lead to the accidental exposure of private data is staggering. Copies of sensitive data that are not properly cared for can easily be transferred and stored in places and websites where they shouldn’t. When data is exposed to the public, malicious actors can take advantage.

To prevent accidental exposure of valuable data, you need to take a more cautious, zero-trust approach. Don’t assume your antimalware suite will mitigate all risks. Restricted access must be placed on all databases that store sensitive data. 2FA (two-factor authentication) must be used on all passwords. And staff awareness training can be vital in preventing any data leaks and exposures that could spell disaster.

Four. man-in-the-middle attack

Some of the smartest cyberattacks are the most cunning. A man-in-the-middle (MITM) attack is when an attacker impersonates a trusted third party and steals data from a computer or network.

Wearing a mask and pretending to be who they are not, they can sneak in and steal your most private data. Names, email addresses, dates of birth, financial information, and other types of personal information may be at the mercy of these crooks.

Prevention of MITM attacks is achieved by ensuring that basic security elements are implemented. A secure network connection is a good place to start. Install 2FA for passwords. Use a VPN when on public networks. And keep everything, including your network, fully up-to-date with the latest software and security patches.

5. data in motion

With this type of data breach, the clue is in the name. Open networks without proper encryption are one of the most common ways cybercriminals can leak personal data. They move it across networks, sometimes in large batches, moving crucial data through network conduits.

The key to keeping data from moving is to make sure all of your networks are properly encrypted. This is standard today, but sometimes network settings change or security updates interfere. It’s worth checking that your networks are encrypted every six to twelve months.

6. SQL injection attack

SQL injection attacks are notoriously vicious. In these attacks, malicious code enters a system through SQL rather than HTML data. The attacker’s malicious code breaches a system through a database.

The most common finding in successful SQL injection attacks is that they gained access through a web application database as a trusted third party. So it is vital that you verify that the data shared with third parties through your web applications is not shared with unauthorized persons.

7. XSS attack

Cross-site scripting (XSS) attacks are similar to SQL injection attacks. Attackers send malicious code to a web application, targeting XSS vulnerabilities that can give them a backdoor to break in.

Fortunately, the XSS vulnerabilities that lead to these kinds of malicious code attacks are usually easy to identify. You can prevent these types of attacks by ensuring that there is a strong web application firewall and that only data leaked from the allow list can make code changes on the web.


These are just seven of the most common types of data breaches and how to prevent them. Here are some common topics we’ve detailed to maximize your protection, such as using a strong firewall, ensuring your systems and networks are up to date, and staff awareness training.

As the best IT support company in London, we can provide you with the guidance, advice and practices to establish a powerful fortification from all angles that can prevent data breaches. We recommend that your company does not take risks. Invest now and help prevent a future attack that could be devastating to protect your business.
