Argus – the Audit Record Generation and Utilization System is the first implementation of network flow monitoring, and is an ongoing open source network flow monitor project. Started by Carter Bullard in 1984 at Georgia Tech, and developed for cyber security at Carnegie Mellon University in the early 1990s, Argus has been an important ...
Network security is achieved by various tools including firewalls and proxy servers, encryption, logical security and access controls, anti-virus software, and auditing systems such as log management. Firewalls are a very basic part of network security. They are often placed between the private local network and the internet.
The goal of a security assessment (also known as a security audit, security review, or network assessment [1]), is to ensure that necessary security controls are integrated into the design and implementation of a project.

Previous research on network security was mostly about using tools to secure transactions and information flow, and how well users knew about and used these tools. However, more recently, the discussion has expanded to consider information security in the broader context of the digital economy and society.
An information technology audit, or information systems audit, is an examination of the management controls within an Information technology (IT) infrastructure and business applications. The evaluation of evidence obtained determines if the information systems are safeguarding assets, maintaining data integrity , and operating effectively to ...
Once the information is categorized, security requirements can be developed. The security requirements should address access control, including network access and physical access; data management and data access; environmental controls (power, air conditioning, etc.) and off-line storage; human resource security; and audit trails and usage records.
Auditing the security of a device or firewall by identifying the network connections which can be made to, or through it. [14] Identifying open ports on a target host in preparation for auditing. [15] Network inventory, network mapping, maintenance and asset management. [16] Auditing the security of a network by identifying new servers. [17]
In some related but distinct contexts, the term AAA has been used to refer to protocol-specific information. For example, Diameter uses the URI scheme AAA, which also stands for "Authentication, Authorization and Accounting", as well as the Diameter-based Protocol AAAS, which stands for "Authentication, Authorization and Accounting with Secure Transport".
