Audit Logs Management and Security - A Survey

Abstract

Audit logs are key resources that show the current state of the systems and user activities and are used for cyber forensics and maintenance. These logs are the only source that can help in finding traces of some malicious activities or troubleshooting a system failure. Insight view for troublefree availability of computing resources and performance monitoring and meaningful forensic audit depends on the management and archival system of audit logs. These logs are prone to multidimensional threats and superusers or system administrators have unprecedented access to these logs and can alter these logs as and when required. Similarly, repudiation is another serious issue in computer forensics and non-repudiation can be provided by a secure recording of event logs. Periodic backups, encrypted data transfer, off-site storage and certificate based storage of these logs are commonly being used. In this survey, we searched for the requirements of securing audit logs and available approaches to secure these logs. Based on the available literature, a taxonomy of audit log management is developed. We have drawn a comparison between these approaches and also highlighted the current challenges to these logs security and their available options.

An adaptive data-driven architecture for mental health care applications

“…Audit logs and monitoring play a crucial role in detecting and responding to potential security breaches ( Yang et al, 2021 ). By monitoring access logs and system activities, organizations can identify suspicious behavior and take prompt action ( Ali, Ahmed & Khan, 2021 ). Fraud analytics, an emerging field, utilizes advanced data analytics techniques to detect and prevent fraudulent activities ( Ai et al, 2022 ).…”

Clustered event2ledger: Docker event traceability using consortium Hyperledger blockchains

“…Attacks, in turn, are actions taken by threat sources who use tools or techniques to exploit vulnerabilities to damage a system or interfere with its operations. The main security attacks against monitoring solutions are divided into four groups, as defined in [9] and, in addition, we considered a fifth group, as suggested in [1]:…”

“…Figure 8 gives a general overview of the transaction flow in the Hyperledger Fabric blockchain environment. First, a collector receives the event data from Docker and generates a signed transaction sending it to the endorsing peers (1). The endorsing peers execute the received transaction, sign it, and send it to the orderer nodes (2).…”

Implementasi Monitoring Log System Untuk Keamanan dan Integritas Data Akademik

“…Dalam era digital yang terus berkembang, ketersediaan dan pelacakan data menjadi semakin esensial, terutama dalam konteks institusi pendidikan yang memegang peran penting dalam mencetak generasi penerus [1], [2]. Pengelolaan data menjadi jantung dari sistem informasi akademik modern, di mana logging data telah menjadi sarana utama untuk mencatat setiap aktivitas yang terjadi di dalamnya.…”

“…Dalam menghadapi kompleksitas dan dinamika dunia pendidikan saat ini, institusi pendidikan perlu mempertimbangkan implementasi Monitoring Log System sebagai langkah proaktif dalam menjaga integritas dan keamanan data. Sistem ini tidak hanya menyediakan lapisan pertahanan tambahan terhadap ancaman keamanan, tetapi juga membantu mengurangi risiko pelanggaran data yang dapat merugikan integritas institusi [2]- [4].…”
