Final answer:
A full SSN breach has a severe impact, allowing for significant identity theft, whereas exposure of just the last four digits entails a lesser risk but remains concerning. Individuals can take steps like fraud alerts and monitoring, while businesses must adopt rigorous security measures to prevent breaches.
Step-by-step explanation:
Impact of Social Security Number Breaches
A full Social Security Number (SSN) breach has a significant impact because the SSN is often used as a key identifier in many systems and can be used to commit identity theft or True-name Fraud. When a full SSN is stolen, it allows cybercriminals to potentially open new accounts, gain employment, receive tax refunds, and obtain credit, causing extensive financial and personal damage to the victim. A breach involving only the last four digits is less impactful, as these digits alone are less useful for identity theft. However, they can still be used in conjunction with other information to validate the identity of a person, making them still valuable for cybercriminals.
When individuals discover that their information has been stolen, they should report the theft to authorities, place fraud alerts with credit bureaus, and monitor their credit reports and financial accounts closely for any unauthorized activity. Additionally, proactive steps such as using strong passwords, regularly updating software, being aware of phishing attempts, and minimizing the sharing of personal information can help protect against identity theft.
Businesses, organizations, and governments are also victims of data breaches, with losses including customer and employee data, financial information, and classified national security details. Preventative measures can include robust cybersecurity practices, employee training, and investment in security technologies to mitigate risks.
