Description: Legacy systems are those computer systems that, despite their age, continue to be used in various organizations. These systems may not meet current security standards, making them a potential risk for data loss prevention. Often, legacy systems are difficult to update or replace due to their complexity and the dependency that organizations have developed around them. Their architecture and technology may be outdated, limiting their ability to integrate with new technological solutions. However, despite their disadvantages, these systems may contain valuable data and critical processes that are essential for a company’s daily operations. Therefore, managing these systems is crucial to ensure information security and business continuity. The lack of technical support and the difficulty in finding personnel trained in old technologies are additional challenges faced by organizations that rely on legacy systems. In this context, it is essential to implement data loss prevention strategies that include regular backups, security audits, and, when possible, migration to more modern and secure systems.
