This information can ensure compliance with regulations and be used as a basis for legal evidence. It also records what change and work was done, when, and by which user. All processes, from creation, through retention, maintenance, usage, to deletion are recorded here. An audit trail logs the various stages of the data lifecycle. An audit trail can effectively minimize data integrity risks. This is where documenting your data handling processes plays a critical role. Finding sources of errors: If an error or manipulation of data does occur, it is important to locate the source and be able to prove changes.Here, it makes sense to proceed according to the "least privilege principle": Only authorized persons can access the data belonging to their area of responsibility. Access controls: Unauthorized access and unauthorized changes can be prevented by access controls.In doing so, backups should be performed as frequently as possible, especially for mission-critical data. Backups protect your business from data loss and ransomware attacks. Back up data: Data backup is one of the most important security measures for successful data integrity, as it protects against permanent data loss.A Self-healing function automate the detection and repair of inconsistent data. An archiving system should be able to check and guarantee the integrity of the stored data. So-called hash values, which are attached to files, can be used to identify modified or damaged data. Validate data: Use checksums to keep track of record consistency.This often happens unnoticed until malware is activated on the system by the attacker or a ransom demand is made. In addition, hardware can be compromised. Cyber-attacks: Cyber-attacks can allow malware to enter IT systems and manipulate, delete, or encrypt data records.Referential integrity also includes the rules that dictate what types of data manipulation are allowed on referenced values and how. Data Integrity is the assurance that information is unchanged from its source, and has not been accidentally or maliciously modified, altered or destroyed. ![]() For example, content-related and important meta-information such as retention period, timestamps, or IDs can be lost. A referential integrity rule is a rule defined on a key (a column or set of columns) in one table that guarantees that the values in that key match the values in a key in a related table (the referenced value). This moving can result in transfer errors, which can lead to damage or loss of sensitive or critical data. This involves transferring data from one system to another. ![]() ![]()
