A serious physical security breach happened in December $2021$ at the Ledger offices in Paris, France. Ledger is a company that makes hardware wallets for cryptocurrencies. The incident involved a third party physically entering the company's premises without authorization. By eluding security safeguards, the burglar gained access to places holding confidential data.

Employees who spotted strange activity in the office found the breach. The business alerted local law police and started an internal inquiry right away. Although Ledger informed its clients that no financial or personal information was exposed, the precise nature of the information that was accessed or stolen is yet unknown. However, the incident has damaged the company's brand and given rise to grave concerns regarding its physical security procedures.

Upon closer inspection, it seems that Ledger's physical security measures were not enough to keep out unwanted access. The fact that the hacker was able to get past these safeguards points to a weakness in their security setup. This event emphasizes how crucial complete physical security is for safeguarding confidential data.

Preventive measures that could have been implemented to stop the incident from occurring include:

$1.$ Enhanced Access Control: It might have been possible to stop unwanted access by putting in place a more reliable access control system, like key card access systems or biometric scanners.

$2.$ Surveillance Systems: Early detection of the intruder's presence may have been achieved with a thorough surveillance system that included CCTV cameras and motion detectors.

$3.$ Security Personnel: Having security guards on duty, particularly after hours, might have prevented or caught the intruder.

$4.$ Regular Security Audits: Physical security measures should have been routinely audited to spot possible weaknesses and make necessary adjustments before the intrusion happened.

$5.$ Employee Training: The hack may have been discovered sooner if staff members had received regular training on security procedures and how to handle suspicious activity.
