Have you ever experienced a security incident involving data?

This can be one of the great disruptions that a company can face. The loss, theft or leak of data generates various types of losses, which you can recall by reading this post.

However, to understand that it is key to create an efficient defense scheme, there is no need to be actually disrupted. Many data leakage recent episodes can serve as lessons for your company to avoid potential losses.

By evaluating these recent episodes, we can learn three important lessons:


Get to know the norms of your industry

Most companies use digital resources and face ever more sophisticated threats. Depending on the market in which the company operates, the type of customers etc., there are specific legislations that need to be respected to ensure more security.

For example, payment transactions should comply with PCI-DSS; health institutions must follow HIPAA.

These norms are very important as they help to create guidelines for protecting data. On the other hand, in the event of an incident, the existence of legislation represents a common ground of legal security.

In particular, the current challenge for companies all over the world is to know and adopt measures to comply with the rules of GDPR – General Data Protection Regulation.


Identify in advance the vulnerabilities of your environment

Prevention is the key word of information security.

To create an increasingly preventive attitude, companies have been adopting tools that can scan their environments for gaps. This enables potential gaps to be addressed before they are exploited by attackers – whether through intrusion incidents or through the spread of malicious applications.

This approach can be adopted through punctual actions, with the execution of intrusion tests; or through an ongoing process of vulnerability management.

On the other hand, it is equally important to respond to digital threats with active threat detection technology, using multiple layers of security and keeping your software up-to-date.


Build an incident response plan

Security policy should always be a step prior to adopting any information security tool.


It is essential to know the entire context of data usage, systems, privileges, procedures etc. to establish a plan tailored to the needs of each company. Most plans are not put into practice because they do not reflect the real need for data protection tools applied to a given environment.

A response plan should be detailed. This means: identify all the scenarios that pose risks to the data and ways to resolve each case. That is, it is not worth adopting a general plan that does not come close to the scope of your company.

As part of your security policy and youe incident response plan, it is also important to prioritize training. The cyber-threat scenario changes very quickly and it is always necessary to prepare your security team for new threats and prevention methodologies.
