Active and Passive Network Monitoring: Tools and Techniques

Network monitoring is an essential practice for maintaining the security and performance of computer networks. Active and passive monitoring are two common approaches used to observe and analyze network traffic. Active monitoring involves injecting test traffic into the network, while passive monitoring focuses on observing existing network traffic. This article explores the concepts of active and passive network monitoring, discusses popular tools like Wireshark, Active Network Monitor (ANM), DNS tools, and Nmap, and highlights their functionalities in network analysis and troubleshooting. By leveraging these network monitoring tools, organizations can proactively detect issues, identify potential threats, and ensure the smooth operation of their networks.

Database Transactional-Based Fraud: Enhancing Transaction Security and Addressing the Halloween Problem

Database Transactional Based Fraud and the Halloween Problem are significant concerns in the realm of database security. Malicious transactions pose a risk to data integrity and availability, yet detecting and identifying attackers executing such transactions remains a challenge. This article explores the concept of Database Malicious Transactions Detector (DBMTD), a proposed mechanism consisting of transaction profiling and intrusion detection phases. It discusses the importance of transaction profiling in identifying authorized transactions and describes the auditing mechanism that collects crucial information about executed commands. Additionally, the article delves into the infamous “Halloween Problem” in SQL UPDATE queries, highlighting the need for proper handling of database changes to avoid unintended consequences. By understanding these concepts, organizations can enhance their database security measures and protect against transactional fraud while ensuring accurate and efficient data management.

Schema-Based Access Control for SQL Server Databases

Schema-Based Access Control for SQL Server Databases explores the importance of implementing effective access controls in database systems. The article highlights the principle of least privilege, emphasizing that all users, including Database Administrators (DBAs), should only have permissions relevant to their job. It introduces a structured schema-based approach to access control using ANSI SQL permissions hierarchy and database roles. This approach simplifies assigning permissions and ensures that users inherit the necessary privileges at the schema level. The article also references the role-based security in SQL Server, allowing permissions to be assigned to roles or groups of users rather than individual users. It provides insights into fixed server and fixed database roles and their predefined permissions. By mapping logins to database user accounts and adding them to appropriate roles, effective access control can be achieved in SQL Server databases.

NoSQL Databases vs Relational Databases: A Comparative Analysis
