A security breach is known as an unauthorized access to data, applications, services, networks, and devices, bypassing the underlying security mechanisms. A security breach occurs when a person or hacker enters a private, confidential or unauthorized IT area illegally. A security breach is also referred to as compromising security.

In a situation whereby security policies, procedures, or systems are violated, this is known as security breach. However a security breach can range from low to very high risk which depends mainly on the nature of the incident.

Note: Software or hardware firewalls are majorly used to monitor security breach in companies or large organization to counter cyber criminals. The software firewall sends notification to the network or security administrator immediately a suspicious login is detected. This method helps lower the chance of data breach in companies.

1. How do you know if your data is breached?

If you have adequate security software, you can be notified when data is being downloaded from your network. Security logs must contain records of suspicious activity.

It’s also possible that security software is not working and you find it difficult to know on time, but when you get a call from an angry customer or law enforcement then you know your security has been breached.

2. Methods used in data security breach

Although a data breach may be due to an innocent error, actual harm is possible if the unauthorized person steals and sells personal data or intellectual business data for financial gain or damage.

Those involve in security breach tend to follow a basic pattern because targeting an organization in a violation requires planning. They investigate their victims to find out where the vulnerabilities are, such as missing updates, and the vulnerability of employees to phishing campaigns.

Once they know the weaknesses of a goal, they develop a campaign to get insiders to accidentally download malicious software or directly attack the network. The malicious hackers has the freedom to search for the data they want and with a lot of time since the determination of an average violation takes more than five months.

Common attack methods include following:

2.1. Stolen credentials

The vast majority of privacy breaches are caused by stolen or weak credentials. If malicious mastermind has your user name and password combination, they have an open door on your network. Because most people recycle passwords, cybercriminals can access emails, websites, bank accounts, and other sources of personal or financial information.

2.2. Third party access

Although you can do everything in your power to protect your network and your data, malicious hackers can use third-party providers to gain access to your system.

2.3. Mobile devices

When employees are allowed to bring their own devices to work, unsecured devices can easily download applications that contain malware used by hackers to obtain data stored on the device. This often includes emails and business files as well as personal information of the owner.

3. What to do when your data is breached
  • Reset your password
  • Monitor your credit accounts
  • Consider a credit freeze
  • Watch your inbox carefully
  • Consider credit monitoring services
  • Use multi-factor authentication (MFA)

A data breach can have a devastating effect on an organization’s reputation and also affect the financial stability of an individual.

4. How to prevent a data security breach

A data breach occurs when cybercriminals can access confidential information without permission. Data breach affects the information of both customers and businesses either small or large organization. These cybercriminals are fast and invisible.

You may cause data breaches when accessing customer accounts, names, passwords, or credit card information because your company’s information system has inadequate security practices and other vulnerabilities.

Listed below are useful tips that will help you to protect yourself from a data breach:

– Update your software

Get used to updating your software regularly. Once a new software is released for update, review the new update and take immediate action. Once the software vulnerability update has been released, your network can be easily attacked.

You must immediately perform all security-related software updates. Keep in mind that hackers have tools that allow them to quickly search a large number of websites to find and exploit vulnerabilities.

– Offer training on data security

Train your team to maintain the best safety practices. Inform everyone about the critical nature of data security and the prevention of errors that can lead to violations. Your employees must learn to identify sensitive data and integrate security into their corporate culture.

– Strengthen network security

Your staff can provide hackers with unauthorized access to your web servers. You must therefore ensure that:

  • Users change their passwords regularly
  • All users use strong passwords that are not in the dictionary.
  • All credentials expire if the user is not used for several months.
  • Devices connected to the network are automatically scanned for malware.

Note: The use of data encryption can also boost security. Data encryption prevents hackers from easily accessing data from one computer to another using malware.

– Install security applications that are reliable

When you install security plug-ins on your blog or on your WordPress website you don’t only protect your site from malicious robots but also from cyber criminals, because these malicious robots search the Internet for a certain version of WordPress and try to exploit known vulnerabilities.

– Disable automatic form filling

Do not let users use the autocomplete feature on your site because it exposes the user information to a high risk of data breach. Ask users to keep their credentials confidential and to ensure that your site forms are not used to insert malicious data or code into your database.

– Improve access control

It’s very difficult for hackers to access your site’s admin panel, put it into action to regularly change administrator username and password. Change the prefix of your default database table and limit the number of login attempts in a given time period. Do not send e-mail connection details because an unauthorized user may have hacked the e-mail account.
