How to Protect Your Website from Hackers and Data Breaches

The number of website data breaches is steadily growing. Statista data shows the number of U.S. breaches rose from 662 to more than a thousand in recent years.

Some industries like government and healthcare have been particularly affected. For instance, recent data by Verizon shows data breaches in the healthcare industry increased by 58 percent.

Data Breach

You may be thinking, “What is a website data breach exactly, and should I be worried?”

Like most things in technology, there are no one-size-fits-all warning signs and solutions for website data breaches. However, understanding what these threats entail and learning effective ways to prevent and deal with them can make a huge difference to your business.


What Is a Website Data-Breach?

A data breach occurs when information is taken from a system without the owner’s knowledge or authorization. This stolen data may include confidential details, personal data, trade secrets, and even sensitive information that could majorly threaten the organization’s security.

How to Protect Your Website from Hackers and Data Breaches

Some common examples of data stolen during a website data breach include:

  • stolen passwords
  • identity information (date of birth, email ID, location, etc.)
  • credit card information
  • banking details
  • medical history

If a data breach occurs and this information is stolen for misuse, it could mean harm for both the business and the person whose information is being taken.

Think about it: If you’re a business owner handling sensitive customer information such as their financial history, you must protect this data. When a website data breach occurs, these personal details can be misused, leading to identity theft, empty bank accounts, and unauthorized transfers among other types of fraud.

Ecommerce businesses need to be particularly careful about website data breaches as most of their dealings happen online, so nearly all the information is at risk.

This is important because you’re not just losing data but also money. Consider this: Data by RiskIQ suggests cybercrime costs organizations $2.9 million every minute, and major businesses lose $25 per minute as a result of data breaches.

Do you still want to risk a data breach?


What Causes Data Breaches?

A data breach doesn’t need a trained hacker. Something as simple as losing your device can be enough for a website data breach to occur. Some other causes of website breaches include:



Various types of hackers work alone or in teams to compromise and sell sensitive data. This is one of the leading causes of data breaches and tends to cause the most damage as not only could you lose the data, but your entire system could be compromised.


Accidental access:

Writing and blogging

If you’ve ever logged in to a coworker’s computer for a minute and got access to sensitive information you weren’t supposed to see, it’s a data breach. This happens more often than you’d think, as many colleagues sometimes share a device to work on a common project.


Internal spy:

If an employee inside the company shares information to outsiders for money or other gains, the data is breached by an “internal spy.”

While these causes can be dangerous for businesses dealing with sensitive data (think payment processing apps), most of them can be prevented. To help you bolster your security, below we’ll talk more about common data breach strategies and how to protect your business against them.


What Strategies Do People Use to Cause Data Breaches?

There are various strategies people use to cause website data breaches. These can be spontaneous or well-planned depending on the type of data being breached, whether it’s a solo or a team venture, and the purpose of the breach.

Here are some of the most common strategies cybersecurity experts recommend watching out for:


Phishing attacks are designed to fool users into giving up their information. These look like genuine messages from trusted institutions but actually are clever traps designed by hackers to get access to your data.

Users who are not tech-savvy or those in a hurry may accidentally click on the false links and give away important information straight to the fraudsters.

Here’s an example of a phishing email impersonating Netflix:

Brute Force

Brute force attacks cause website data breaches by working through all possible combinations to crack your passwords. This used to take a long time as there could be endless variations of letters, numbers, and symbols to try, but nowadays the use of sophisticated software makes this process much easier. In fact, some hackers use fully automated brute force attacks.

Malware attacks capitalize on your device’s security flaws to gain access to your system. Hackers shove viruses and spyware into your system to view, access, lock or change your files, which causes a massive data breach.

In fact, data shows nearly half of the security professionals surveyed say ransomware and malware pose the biggest IT risks, so businesses should be extra careful to protect themselves against such cyber threats.


How to Prevent Data Breaches

While every business that operates online faces some cyber threats, there are many ways to prevent data breaches or at least minimize their impact. Let’s take a look at some of them below.

Look for Vulnerabilities

No system is perfect. Every system, network, server, and the device has a flaw that hackers use to grab access. The sooner you identify these flaws, the better you can protect your business from website data breaches.

One way to do this is to proactively look for vulnerabilities in your security system. You can do this by using security software specifically designed to test your system for such vulnerabilities.

Data Warehouse

If you don’t want to rely on software, there’s another option for you. Many companies hire trained white-hat hackers to spot system vulnerabilities and patch them before other hackers can get a chance. This is more time-consuming but can also offer more reliable results, especially when it comes to larger organizations handling a lot of data.

Human testers are also better at recognizing patterns, so if there’s a recurring issue, paid white-hat hackers might be able to identify the problem before it’s too late.


Train Your Employees

While human testers can be a great benefit to your organization, sometimes it’s your very own employees causing the very breaches you are trying to prevent.

Many incidents of website data breaches occur when employees accidentally leak information to people who do not have authorized access to this data.

Employee Insider-Threats

For instance, if an employee accidentally emails private information to a third-party client, or if sensitive information is leaked through a shared device in the office, this data is considered to be “accidentally” breached.

It’s still harmful to the company, but it’s caused by human error, often due to the employee’s negligence, lack of technical knowledge, or skills in handling data.

Accidental website data breaches like these are easy to prevent through appropriate employee training to improve their understanding of data management. Organizations can use various programs like the Polymer DLP Behavioral Approach to training up their employees on cybersecurity.

If a complete program is too big of a time or budget commitment, consider hosting small webinars. Invite a guest speaker or show a documentary that highlights the impact accidental website data breaches can have on a company, and how to prevent them.

These might sound like small steps offering minimal results, but training your employees early on can go a long way in securing your organization and minimizing the chance of accidental data breaches down the road.


Have Backups for Your Data

In some cases, despite your best attempts at preventing them, a website data breach can wipe out important information from your system. While it may or may not be able to be recovered, it’s always a good idea to backup any and all information that might be important.

This way, if data is stolen, you’re not completely lost. You still have something to fall back on. For this, you can invest in a cloud backup solution or use a third-party service depends on your company’s needs.

Install a Firewall

Firewalls are one of the most basic yet secure ways to defend yourself against website data breaches. By installing a firewall, you will prevent unauthorized traffic and malicious software from entering your network.

This can act as the first line of defense and work well with other security measures to minimize the threat of hackers and other cybercrime.


Encrypt Sensitive Data

The process of encryption involves encoding data in a way that only authorized parties can read it. This is another basic but effective strategy to protect your business against website data breaches.

Different types of encryption processes can safeguard confidential data that is only meant to be shared with specific people in an organization. Only these people will be able to access and share it, keeping it in tight circles.

Online payment apps, email service providers, and messaging apps like WhatsApp use encryption to protect user privacy and boost security around sharing personal information on these platforms.

Monitor Database Activity

Want something that gives you a high-level view of your security system? Consider monitoring database activity. This might be a new concept for many teams who are still in the early stages of adopting data security tech, but it’s worth taking a look at and can be effective for organizations of all sizes.

A database activity monitor (DAM) observes, identifies, and reports on database activities. These monitoring tools use real-time security technology to monitor all actions across the database. Additionally, they can detect abnormal and unauthorized activity, internally and externally, while gauging the effectiveness of your existing security protocols.

Like most other measures, this has multiple layers, and it’s important to consider your security needs before implementing any complex programs.
