SMEs Data Breach - Examples That Will Be Remembered


Table of content:

 



Intro

 

In recent years, there have been several high-profile data breaches at small and medium-sized businesses (SMEs) due to inadequate data protection. These breaches have resulted in the loss of sensitive data, financial damage, and reputational damage for the businesses involved. In this blog post, we'll take a look at some of the most memorable data breaches of recent years.





What constitutes a data breach?

 

A data breach occurs anytime that confidential, protected, or sensitive information is accessed without the proper authorization. This can be done by accident such as with a negligent employee or it can be the result of a hacker gaining access to company data and releasing it to the public. Either way, anytime data is accessed by people without the proper authorization this will constitute a data breach for that company.

 

 

What is the cost of a data breach?

 

Data breaches can be extremely expensive for companies. The average cost of a data breach in 2019 was $3.92 million. This alone would explain why companies should invest heavily in security but the costs are not just strictly financial. 

 

On average, companies' share prices dip by 5% following a data breach and there’s also significant reputational damage depending on the type of data that is leaked as a result. 

 

For example, the company Ashley Madison, which is a dating site to facilitate affairs among married people had a data breach back in 2015.

 

This type of information being leaked could seriously damage the company’s customers’ personal lives. This opened up Ashley Madison to lawsuits as well as loss of customers that refused to trust the company after having their data leaked. 

 

 

What are the biggest factors that cause data breaches?

 

One of the most common questions we get asked is "What are the most common causes of data breaches?" This is important to understand from a business perspective so that you can plan out how you are going to guard against these risks. Here are some of the most common causes of data breaches:- weak or stolen passwords- unsecured data- malware or viruses- insider threats- phishing attacks (social engineering)- leaked data on social media

While LinkedIn has since recovered from the breach, it serves as a reminder of the importance of data security. This breach was a major wake-up call for the company, and it is something that all businesses should be prepared for.

 


How to prevent data breaches

 

Data breaches are becoming all too common, and no company is safe from them. To prevent your company from becoming the victim of a data breach, there are a few things you can do, and it all comes down to having good risk management.

 

First, you need to have a strong security system in place. This includes firewalls, intrusion detection systems, encryption, and other information security measures that will help to prevent the initial compromise of your environment.

 

You also need to have a privacy policy that will govern how data is to be used, protected and shared within your organization to limit the number of people that have access to confidential information.


Thirdly, you need to train your employees on how to spot potential security threats and what to do if they encounter one. Additionally, they need to be trained on how to enforce data privacy in an organization, this usually means labeling data with the appropriate sensitivity and knowing when to share information with other employees/third parties.

 

Additionally, you should have a plan in place for what to do in the event of a data breach. This is commonly called an incident response plan and should include who to contact, how to contain the breach, and how to prevent future breaches.

 

Lastly, you should have routine penetration testing done to test your organization’s security posture and ensure the security controls are working as intended.

 

By taking these steps, you can help prevent your company from becoming the victim of a data breach.
