How to Prevent Data Breaches?

Reputation management and data breach are two phrases you don’t want to see together. A data breach can truly cause serious damages to the company, both financial and reputational. I know you never want to happen this with you so here are the ways which can help you to prevent data breaches.


Update software on a regular basis

This is an easy and cost effective method to prevent from attacks. It is very essential to regularly update operating systems and other application software. The networks are sensitive if not patched. Make sure all the programs are patched and updated regularly.


Limit access to the most valuable data

This is a very common but important step. If you limit the access to the most valuable data, you also limit the employee who may click on any harmful link that is directed towards attacks. Let only the concerned department have access to the most important data. For instance, a mailroom employee shouldn’t have the access to go through the customer’s financial information. Also reduce the space where those data are physically stored.


Train the employee

It is sure that the companies have a strong IT Security team but sometimes the security issues are out of their hands. The cybersecurity scenario keeps on changing so it is important to train the employees about the latest cybersecurity practices and policies. The team should also educate the employees about the potential risks.


Vulnerability and Compliance Management

Prevention is better than cure. Perform various kinds of vulnerability assessment and penetration testing on your critical infrastructure which will help you to identify the gaps, weaknesses, and security misconfiguration. It also helps you to continuously monitor your infrastructure and IT asses for vulnerabilities and compliance weakness and configuration best practices.


 Observe the Third-party vendors

All the companies get connected with many third-party vendors. It is important to know about the people you are working with. Before getting connected with any third party, check the background and the reputation. Ask transparency if you allow any company to view your data. Similarly, also observe any third party vendor that you allow in your office premises.


Monitor the devices

Many companies have a culture of asking their employees to use their own devices at work. But this can be a great risk as they use their personal devices. Employees use it for work and also for their personal needs. The breaches can also occur due to this. It is important to monitor those devices as well.


Notify early

As soon as you realized about the data breach, inform your security team about it immediately. If the management knows about the breach at early stage, they will have higher chances to control it and minimize the loss. Even if you notice any sort of suspicious act or any unusual act, report it early. This can change the major breach to a minor one.
