Once an intruder gains access to an IT ecosystem, any logs stored on that system, or in a situation to which that system has access, must be considered compromised and suspect. This loss of data integrity results in significant expenses for enterprises. Maintaining accurate and comprehensive user access logs is a critical part of detecting hackers and other unauthorized access events to IT environments. However, administrators frequently house the records of user access on logs directly on the servers that they are trying to protect, which unfortunately makes those records untrustable. You see, unauthorized access to IT environments is typically conducted by hackers who then cover their tracks by deleting traces of their access from log files or deleting the log files themselves. The only way to mitigate this behavior is by using an external and immutable logging system using blockchain, so that information logged there is permanent, unchangeable and verifiable, unlike local logs. By also writing data to a blockchain using ULedger, companies are creating permanent and tamper-proof copies of log data. Continual comparisons between the two are performed, and, since it’s impossible to delete data from the blockchain-based copy, any discrepancy found between the operational logs and the blockchain-based copies indicates malicious activity. Another reason that companies rely on our assistance for intrusion detection is that unlike a public blockchain, Lirax Blockchain is infinitely scalable, controlling costs and keeping transaction per second high.
