What is Data Breach: What To Do Before, During & After a Data Breach

Have you ever wondered, "What a data breach is, and could it happen to my business?" You're not alone. In this digital age, understanding what a data breach is becomes crucial for every business owner, just like you.

A data breach is when someone gets unauthorized access to your confidential information – think of it as a digital break-in where your business's sensitive data is the target. But why you? Well, every business, big or small, has valuable data that can attract unwanted attention.

That's why in this blog, we'll teach you the immediate actions to take before, during, and after a data breach. 

Data breach definition: What is a data breach? 

What is a data breach? Well, it is a serious security incident where confidential, sensitive, or protected information is accessed or disclosed without authorization. This breach can occur through various means: cyberattacks like phishing, malware, or exploiting software vulnerabilities.

Imagine you have a secure locker for your business's sensitive data – customer details, financial records, proprietary information. Now, if someone finds a way to break the lock or sneak in a backdoor without your permission, that's a data breach. This unauthorized access can lead to data being viewed, stolen, or even sold.

The impact of a data breach can damage your business's reputation, lead to financial losses, and even legal consequences. That's why understanding the answer to "what is data breach" is important. 

What are the three types of data breach examples? 

After understanding "what a data breach is," let's dive into the three main kinds of data breaches: Credential theft, phishing, and human error, and explore how they can impact your business operations and what measures you can take to prevent them.

1. Credential theft

Credential theft is a major type of data breach where cybercriminals get their hands on your login details, like usernames and passwords. This theft often happens through methods like spyware, where malware secretly installed on your computer records your keystrokes. Or it could be through a security breach at a service you use, where hackers get access to a trove of login details.

For your business, this means if one of your team members’ credentials is compromised, hackers could access sensitive company information, client data, or financial records. That's why it's crucial to have strong, unique passwords for each service you use and to implement multi-factor authentication.

2. Phishing

What is a data breach that's disastrous for your business? That's called phishing. This type of data breach is a deceptively simple yet effective way hackers trick you into giving up your personal information.

Imagine getting an email that looks like it’s from a trusted source – maybe your bank or a familiar software provider – asking you to click on a link or download an attachment. This link or attachment can then install malware on your system or lead you to a fake website where you inadvertently enter your credentials.

A staff member might also receive an email that appears to be from management or a trusted vendor and, without realizing it, give away sensitive company information or login details. Training your team to recognize and report phishing attempts is a key defense strategy against this.

3. Human error

The third kind of data breach, human error, is often overlooked but can be just as damaging as the more technical threats. This could be an employee accidentally sharing sensitive files with the wrong people, misconfiguring databases, or even losing devices like laptops or USB drives that contain sensitive data.

Preventing human error-related breaches involves training, policies, and technology. Your team needs to be aware of the importance of data security and trained on best practices, like double-checking email recipients or encrypting sensitive files. Additionally, implementing access controls and automated alerts for unusual activities can significantly reduce the risk of such breaches.

Before you become a data breach victim: How do you prevent data breaches? 

It’s not enough to ask, "What is a data breach," knowing how to prevent yourself from becoming a victim is the first necessary step. Here's how you can protect your data: 

Implement robust password policies

One of the simplest yet most effective steps is to enforce strong password policies. Ensure that all your employees use complex passwords – a mix of letters, numbers, and symbols – and change them regularly. Also, consider using password managers to store and manage these passwords securely.

Activate Multi-Factor Authentication (MFA)

MFA adds an extra layer of security beyond just a password. Even if someone gets hold of your password, they won’t be able to access your system without this additional verification, which could be a fingerprint, a text message code, or an authenticator app.

Regularly update software and systems

Outdated software is a prime target for hackers. Regular updates patch security holes and fix vulnerabilities. Make sure all your systems, including antivirus and firewall software, are up to date.

Educate your employees

Human error is a significant cause of data breaches. Conduct regular training sessions to keep your team aware of the latest cyber threats and best practices for data security. They should know how to recognize phishing emails, the importance of not sharing passwords, and the protocol for reporting any suspicious activities.

Secure your networks

Secure your wireless networks with strong encryption protocols like WPA3. Also, consider setting up a Virtual Private Network (VPN) for remote access, which creates a secure tunnel for data exchange over the internet.

Regular data backups

Ensure regular backups of all critical data and store them in a secure, off-site location. This way, if your data is compromised, you can restore it from these backups without significant loss.

When data breaches happen: Necessary steps you should do during a data breach

Let's say you've already experienced a data breach happening. What are the things you should know or do to prevent attackers from getting all your data in one sitting? 

Immediately isolate affected systems

As soon as you detect a breach, isolate the affected systems. Disconnect them from the internet and your network to prevent the breach from spreading. This could involve taking servers offline, disconnecting workstations, or temporarily shutting down your website.

Assess the breach

Once you've understood what a data breach is and contained it, it's time to assess the extent of the damage. Identify what data was accessed or stolen. Was it customer information, financial data, or sensitive business intelligence? Understanding the scope of the breach helps in formulating an effective response strategy.

Notify the relevant authorities

If the breach involves sensitive information like personal data or financial records, it's important to notify the relevant authorities. This may include law enforcement, data protection agencies, or other regulatory bodies. 

Communicate with stakeholders

Transparency is key in managing a data breach. Inform your employees, customers, and partners about the breach and what steps you’re taking to address it. Clear communication can help maintain trust and manage the potential fallout from the breach.

Engage cybersecurity experts

If you don’t have an in-house IT security team, now’s the time to bring in cybersecurity experts like the people from 365 Managed IT. They can help identify how the breach occurred, restore systems safely, and strengthen your defenses to prevent future breaches.

When attackers successfully steal data: What to do after a data breach

When you're hit with a data breach, the aftermath can feel overwhelming. However, understanding what a data breach is and knowing the right steps to take can make a big difference in controlling the situation. 

Investigate the extent of the damage

First up, you need to figure out the extent of the breach. What type of data was stolen? Was it customer data, financial information, or sensitive business intelligence? This will help you understand the severity of the breach and shape your response strategy.

Inform the affected parties

Now, it's time to inform those affected. This could be your customers, employees, or business partners. Let them know what happened, what information was involved, and how you’re handling the situation. This step is not just about maintaining trust; it's also often legally required.

Hire cybersecurity professionals

If you don’t have a cybersecurity team on standby, this is when you bring in the experts from 365 Managed IT. They can conduct a thorough investigation to understand how the breach occurred and suggest measures to prevent such incidents. These experts will also help in securely restoring your systems.

Monitor for fraudulent activities

Keep a close eye on your accounts and systems for any unusual activity following the breach. If personal or financial data was involved, advise those affected to monitor their accounts for any signs of identity theft or fraud.

Review and revise policies and protocols

Take this experience as a learning opportunity to understand more about what a data breach is. Review your current policies and procedures. What can be improved? Maybe it’s time to establish stricter access controls or data encryption protocols. 

Prepare for legal consequences

Finally, brace yourself for potential legal fallout. This could involve lawsuits or regulatory fines, depending on the nature of the data breach. Consult with legal professionals to navigate this terrain and understand your obligations.
