When a company experiences a data breach, it can cause long-term damage to its reputation and trust with customers. It also can lead to financial losses, fines and legal costs. There are a variety of reasons why data breaches happen, including phishing attacks by hackers who steal information to profit or hurt businesses, unencrypted devices that get lost or stolen, and human error. Prevention efforts can reduce the risk of a data breach, but they cannot eliminate it.
In the most serious cases, a data breach can expose confidential personal information (PII). This includes names, Social Security numbers, addresses, phone numbers and email addresses. PII can be used to commit identity theft, fraud and other crimes.
Identify the source and scope of the data breach. This is a critical first step to contain the breach and investigate its cause. It may involve hiring forensics experts to capture forensic images of affected machines, collect and analyze evidence and provide remediation recommendations.
It’s also important to review a breach investigation plan template to ensure you have everything documented. This will include recording the date and time when you identified the breach, what data was exposed and how it was discovered. It should also cover who had access to the breached information, how it was accessed and whether those individuals still have access after the incident. Also, you’ll want to look at your network segmentation, determine who has access now and change their privileges if necessary.
