Check out this white paper to learn about two network protocol models, TCP/IP and OSI. 

For many years network administrators have expected security breaches to come from outside an organization or at the upper layers of the OSI model. This paper will focus on securing layer 2 switching at the access layer through port security and preventing denial of service (DoS) attacks at layer 2. 

Data abstraction overcomes data structure incompatibility by transforming data from its native structure and syntax into reusable views and data services. But some data abstraction approaches work better than others. Composite data virtualization is an optimal way to implement an abstraction layer at enterprise scale. 

A new approach to Business Process Management (BPM) is the use of BPM and SOA together in a layering strategy. This white paper explores the BPM layered concept and offers a case study of how ABN AMRO, one of the world's largest financial institutions, has benefited from its deployment. 

This paper outlines the things you must consider when thinking about the feasibility of replacing a WAN provider’s provider (P) and provider edge (PE) devices with routers. This paper examines these considerations in greater detail, to see where any potential problems might arise. 

Gain insight into the value of a new technology, overlay transport virtualization (OTV), in this expert resource. OTV enables network scaling and the moving of components of the data center from one side to the other. 

This resource explores an innovative, market leading mobile security solution that mitigates the risks associated with deploying IP-based services. 

Typical IT departments feature islands of isolated infrastructure, leading to inefficient use of servers. The "application grid" concept allows data centres to run more efficiently, using less hardware and less software. This paper explains. 

In this paper, learn why the database layer is so important to the software selection of an enterprise resource planning (ERP) system. Also compare Oracle database to SQL Server databases. 

This white paper details the security features in each layer of Oracle’s integrated end-to-end solution stack, including infrastructure, database, middleware and application security, as well as the economic benefits of deploying a defense-in-depth strategy. 

Any virtualization layer or hypervisor introduces a new set of demands to a server or blade environment. This e-book explains the process of virtualizing the I/O layer, how to manage it and what challenges remain for this disruptive technology. 

In order to combat the ever-evolving challenges of today’s networks, it’s time to head back to school in our exclusive Network Evolution University – Featuring three distinct classes and nine progressive learning lessons that explore all there is to know about next generation networks and how to overcome the challenges they present. 

Security professionals know that effective endpoint protection calls for a layered, defense-in-depth approach. But endpoint security now requires a new way of thinking that goes beyond just battling threats to actually enable operational improvement. Read this whitepaper to learn the six steps you need to think different about endpoint security.
