Year in Review: Notable Data Breaches for 2017
Data breaches have become one of the most prevalent cybersecurity incidents around the globe, and it seems the trend is going to continue. In fact, more records were stolen and leaked in the first half of 2017 alone compared to the total in the whole of 2016.
Many of the incidents that occurred in 2017 were due to the same causes, which include, but are not limited to:
- Security issues with data storage
- Misconfigured security settings
- Lack of actual security solutions to protect data
- Use of unpatched and unsupported software with exploitable vulnerabilities
It is also important to understand that data breaches are neither purely technical nor are they caused solely by human error. Most times, they are caused by a combination of both.
Organizations can mitigate the impact of data breaches through the use of best practices, which include:
- Patching and updating systems on a regular basis
- Implementing measures that can help identify weak spots in an organization’s security requirements
- Creating contingency plans that can address data breaches, including communication with affected parties
- Use security solutions such as Trend Micro™ Hybrid Cloud Security that can offer effective protection against data breach attacks on the cloud, and Trend Micro Deep Security, which protects millions of physical, virtual, and cloud servers around the world. In addition, TippingPoint can help organizations manage their legacy systems and control their patch management life cycle by providing added protection for legacy, out-of-support software, delivered weekly or when critical vulnerabilities emerge.
