How does a data breach happen?

Now that you have gained a basic understanding of data breaches and know what they mean, it’s time to find out how they happen.

A “data breach” occurs when a hacker or cybercriminal manipulates the data sources and extracts crucial information from that resource.

It can be done in numerous ways in the case of the latest security breaches. For instance, a hacker can access a computer or network in an unauthorized manner and steal information. Data can also be extracted by bypassing the network security protocols.

Some of the most common tools to make this happen are malware attacks, viruses, phishing, and Denial of Services. However, ways like payment card fraud and insider data leaks are also responsible for many data breaches.

Here are some statistics that you should know about:

  • Out of all the data breaches, happened in 2018, 34% occurred because of an insider’s help.
  • The main motive behind 71% of data breaches is finance-related.
  • Around 4,800 websites become a victim of form jacking code.
  • Hackers become successful in their motives because the

How can you help protect your personal data?

It may seem hard, but it is not impossible; keeping data safe in the world of cyber vulnerabilities is not impossible. All you need a smart preventive strategy and continual monitoring.

Here are some of the most viable ways to protect personal data and keep data breaches at bay:

  • Organizations can update and review their data governance policies frequently and make changes as per the need of the hour.
  • Ensure that data classification and governance are at par with data privacy standards like HIPAA, SOX, and ISO 27001.
  • It is essential to do risk assessment frequently and spot the vulnerabilities in their infancy stage.
  • If you can afford a full-time data security expert, then it’s good. Else, outsource this service. Don’t ever try your hand in this domain. It is something that demands perfection and expertise.

Organizations can reduce the harm of data breaches by creating a viable disaster recovery plan. When there is an effective recovery, data can be recovered easily.

On a personal level, one can use strategies like keeping devices password-protected, using strong passwords, updating software regularly. Don’t get carried away with amazing deals and offers from unrecognized senders. They are no less than a trap.

It is suggested not to carry out important transactions on public or free Wi-Fi. Because this way, you welcome hackers.

What should you do if your personal data were exposed?

We know that it is a heart-breaking and shattering thing to know that your personal data is stolen. Thoughts of getting robbed, blackmailed, or exposed will run in your mind, and it is about to happen. But, you need to maintain your sanity as you are not alone in this. Many leading firms have also faced it.

  • Recently, 80 million Microsoft customer records were exposed online.
  • Hackers leaked 1,852,595 records of in 2020.
  • In every 39 seconds, a cyberattack occurs.
  • Reports say that around 192,000 coronavirus-related cyberattacks occurred every week in May 2020.

So, instead of crying about what has happened, one must try to mitigate the risk and prevent it from happening in the future. This is what a prey of data breach must do soon after the attack.

  • Figure out what kind of attack has happened. Whether your personal information has been stolen or financial credentials have been compromised.
  • Once you figure out what has been stolen, take remedial actions immediately. Change all the passwords and update your account details. In case of financial data theft, contact your bank and report the incident. Ask for an inquiry as well.
  • Enable the two-factor authentication on all your accounts for added security. With this, you will be notified when someone is trying to gain unauthorized access to your dataset.
  • If you feel that a crucial dataset has been stolen, it is better to hire a security expert to find the root cause and recover the data. This is primarily the case with organizations and businesses. But, individuals with heavy loss can also take up this way.
