Data breaches have become increasingly common in the digital age, posing serious consequences for businesses and their customers. And while it might seem like an overwhelming task to prevent a malicious attack, there are several practical steps you can take to protect your business’s information.

In this blog post, we'll discuss why data security is so important, explore different ways of protecting your data from hackers or other cyber security threats, and provide useful tips on how to ensure your company's data remains secure by following latest cyber security trends.

Whether you're a marketer trying to protect customer information or an IT professional seeking solutions for enterprise-level security issues - this blog post has plenty of valuable advice that any data security expert should pay attention to.

Let's start with what data breach attacks are, and the four most common causes of data breaches in this blog post.

What is a data breach?

A data breach or data leak is a security incident in which sensitive data or confidential information is accessed, stolen, or transmitted without the owner's permission.

The causes of a data breach can vary, but some common causes of a data breach include weak passwords, unsecured networks, malware or phishing attacks, and employee negligence.

Common Causes of Data Breaches

Here are 4 common causes of data breaches which include:

1. Unsecured Network Connections

One of the most common causes of data breaches is unsecured network connections. This can include using public Wi-Fi networks that are not encrypted, or having an insecure connection between two computers on a private network.

When data is sent over these types of connections, it can be intercepted by malicious actors and used for nefarious purposes.

To prevent this type of data leaks, organisations should always use secure connections such as virtual private networks (VPNs) or other encryption technologies when sending sensitive data over the internet for data leak detection.

2. Weak Passwords

Another common cause of data breaches is weak passwords. If users are allowed to set their own passwords, they may choose ones that are easy to guess or have been used in previous breaches.

To prevent this type of breach, organisations should require users to create strong passwords that contain a mixture of upper and lowercase letters, numbers, and symbols.

They should also enforce regular password changes to ensure that any compromised passwords are quickly updated.

3. Unpatched Software

Data breach occurs due to unpatched software vulnerabilities. Hackers often exploit known vulnerabilities in applications and operating systems in order to gain access to sensitive information stored on servers or other devices connected to the internet.

To prevent these types of data breaches, organisations must keep their software up-to-date with the latest security patches and updates from vendors.

4. Phishing Attacks

Another way that data breaches happen is by phishing attacks as these are another common cause of data breaches.

These attacks involve sending emails or other forms of communication that appear to come from legitimate sources but actually contain malicious links or attachments designed to infect a system with malware or steal sensitive information such as login credentials or credit card numbers.

To prevent the phishing scams, organisations should educate their employees about phishing tactics and deploy anti-phishing tools such as email filtering solutions that can detect malicious messages before they reach users' inboxes.

How to prevent a data breach?

Here are 15 tactics to prevent data breaches in the most effective way.

1. Implement Strong Access Controls

Data breaches can be prevented by implementing strong access controls. This means that only authorised personnel should have access to sensitive data and systems, and that access should be restricted based on the user’s role and responsibilities.

Access control measures such as multi factor authentication, user activity monitoring, and data encryption can help to ensure that only the right people have access to the right data.

2. Educate Employees

Employee education is key when it comes to preventing data breaches. Employees should be trained on how to spot phishing emails, how to identify suspicious links or attachments, and how to properly handle sensitive information.

Additionally, employees should know what steps to take in the event of a data breach or other security incident.

3. Use Secure Passwords

Using secure passwords is an important step in preventing data breaches. Passwords should be at least 8 characters long and contain a mix of letters, numbers, and symbols.

Additionally, users should never use the same password for multiple accounts or share their passwords with anyone else. You can also use a password manager to prevent data breach risks.

4. Regularly Update Software & Systems

Another way to prevent a data breach is by regularly updating software and systems; this is essential for keeping them secure from cyber attacks.

Software updates often include security patches that address known vulnerabilities in the software or system so it is important to keep them up-to-date at all times.

In addition, operating systems such as Windows 10 also provide regular security updates which should be installed as soon as possible after they are released by Microsoft.

5. Use Firewalls & Antivirus Software

Firewalls and antivirus software are important tools for protecting networks from malicious attacks and viruses.

Firewalls act as a barrier between networks and the internet by blocking unauthorised traffic while antivirus software scans files for malicious codes before they can enter a network or system.

It is important that both of these tools are regularly updated so they can detect new threats as they emerge online.

6. Monitor Network Activity

Monitoring network activity is another way to prevent data breaches from occurring on your network or system.

In addition, network monitoring tools can detect suspicious activity such as unusual login attempts or large amounts of data being transferred out of the network without authorisation which could indicate a potential breach in progress.

By monitoring network activity regularly, you can quickly identify any potential threats before they cause serious damage to your organisation’s infrastructure or data assets.

7. Implement Data Loss Prevention (DLP) Solutions

Data Loss Prevention (DLP) solutions are specialised tools designed specifically to prevent security breaches and data loss due to theft or accidental disclosure by employees within an organisation.

DLP solutions monitor employee activities on company networks for any suspicious behaviour such as getting access to sensitive data and transferring large amounts of data outside of the organisation without authorisation.

If any suspicious activity, such as data leaks, is detected then the security team will alert administrators so that appropriate action can be taken immediately.

8. Perform Regular Backups

Another way to protect against a data breach is through data backup. Performing regular backups of all critical data assets is an important step in ensuring your organisation’s continuity in case of a data breach incidents.

So, one of the important ways to prevent the data breach is by allowing organisations to quickly restore critical systems in case they become corrupted due to malware infection or other forms of attack.

It is recommended that backups are performed daily so that any changes made since the last backup can be restored if needed.

9. Enable Two-Factor Authentication

Another effective way to prevent a data breach is by enabling two-factor authentication (2FA) for all accounts as this can help protect against data breaches.

Moreover, it adds an additional layer of security by requiring users to enter a code sent via text or email when logging into an account.

This makes it much harder for cyber criminals to access sensitive information, even if they manage to obtain a user’s password.

10. Install Intrusion Detection Systems (IDS)

One of the most effective ways to prevent against a data breach is Intrusion Detection Systems (IDS). IDS are advanced security tools and malware detection software designed specifically for detecting malicious activity on networks or systems by security team.

IDS solutions use algorithms and signatures to detect known threats such as malware infections, denial-of-service attacks, brute force attempts etc, allowing administrators to quickly take appropriate action before serious damage occurs.

It is recommended that IDS solutions are installed on all critical networks and systems within an organisation.

11. Utilise Cloud Computing Services

Cloud computing services offer organisations an alternative way of storing their sensitive data offsite rather than hosting it locally on their own servers where it may be vulnerable to attack.

Cloud providers such as Amazon Web Services (AWS), Microsoft Azure etc, offer high levels of security for their customers by providing robust firewalls, encryption technologies etc, making them much more secure than traditional hosting options.

12. Restrict Physical Access To Servers & Networks

Restricting physical access is another way organisations can protect themselves from potential threats such as theft or sabotage from malicious individuals who may gain physical access into server rooms or other areas containing sensitive equipment/data assets.

Organisations should implement measures such as biometric authentication devices at entry points into server rooms/other areas containing sensitive equipment/data assets, so only authorised personnel can gain access.

Additionally organisations should also ensure that all servers/networks are securely locked away when not in use.

13. Perform Penetration Testing

Another way to prevent data breach is by performing regular penetration tests. This helps identify any weaknesses in an organisation’s data security system before attackers do so maliciously.

Penetration tests simulate real world attacks on systems so organisations know where their defences may not hold up under attack scenarios.

14. Conduct Risk Assessments

Conducting regular risk assessments is one of the data breach prevention step which helps organisations identify potential weaknesses in their security systems which could lead to a breach if left unchecked.

A comprehensive risk assessment should involve testing all aspects of security including physical security measures, network architecture, authentication protocols, and employee training procedures.

15. Limit Access Privileges

Another data breach prevention tip is that organisations should limit employee access privileges based on their job roles so that only those with a legitimate need have access sensitive data such as customer data and records or financial documents.

This process of data breach prevention helps minimise the risk of unauthorised access since only those with appropriate authorisation will have permission view certain types of data.

16. Use Secure Connections For Remote Access

When providing remote access for employees working outside the office, organisations must use secure connections such as virtual private networks (VPNs) rather than public Wi-Fi hotspots which are less secure.

In addition, VPNs allow users connect securely over encrypted tunnels which make it difficult for attackers intercept traffic between two endpoints.


The external threats are constantly finding new ways to exploit vulnerabilities in security systems, so it's important to stay vigilant and regularly update your security protocols.

Even with the best security measures in place, it's still possible for a data breach to occur.

It's crucial to have a response plan in place and to act quickly in the event of a breach to minimise the damage and prevent further attacks.
