What to do in the event of a security breach


A security breach can happen to any business, no matter how big or small. When it does, it's important to know what to do in order to minimize the damage and protect your customers and employees. In this blog post, we'll outline the steps you should take in the event of a security breach. We'll also provide tips for preventing a security breach from happening in the first place.

What is a security breach?

A security breach is an unauthorized access or attempted access to data, systems, or networks. A security breach can happen in a number of ways, including through malware, phishing, social engineering, or ransomware.

There are four main steps that companies should take after a security breach:

  1. Stay calm and assess the damage: Assemble your task force and determine what systems and data have been affected.

  2. Contain the breach: once you have determined where the breach occurred, take steps to contain it to avoid further damages. Best practices recommend you disable access to the network, change user passwords and delete sensitive information.

  3. Notify your employees and customers: Let your employees know what has happened and that you are working to resolve the issue.

    Companies must notify their clients as soon as possible, even if the breach does not immediately affect them. Keeping the clients in the loop can significantly decrease the potential damage. 

  4. Start investigating: Begin to piece together what happened and take precautions to prevent future breaches.
