Data breach

Data breach is the unauthorized acquisition of restricted or sensitive information stored on, or transmitted through, computers, computer networks, and other digital devices. It is a type of security exploit which usually involves combination of hacking techniques including brute force, social engineering, malware, and SQL injection.

Data breach occurs when a malicious hacker or an unauthorized person gain access to a network or computer system to extract confidential or sensitive information without an individual’s knowledge or statutory approval. This security breach can lead to identity theft, financial loss, as well as harm to business reputation.

In most cases, the thief seeks to take advantage of the confidential information, whether financial or otherwise. Unauthorized access is usually accomplished by exploiting a security vulnerability or utilizing a valid credential. In some cases, malicious actors are able to access systems to copy, delete, or rotate personal or business data.

Technical prevention measures used to mitigate data breaches are encryption, firewalls, anti-malware, strong passwords, physical security measures, least privilege, multi-factor authentication, patching, as well as secure email, cloud storage, and mobile devices. Appropriate administrative controls such as policy development, incident response, encryption, staff education and training, and data minimization should also be employed.

Using layered security solutions and technologies can help businesses reduce the risk of data breaches occurring. Additionally, organisations should also review and update logs, patch, and monitor security measures on a regular basis for the best protection.
