Computer Network Architecture Training


Used to be IT infrastructure was linked together in a loosely-coupled architecture, tied together via networking technologies such as Ethernet cables and the TCP/IP protocol.

Over the years, things got complicated. Today some networks live in the cloud, some are virtual and some rely on application-to-application connections – yet, networks still connect IT systems together in one way or another.

Amid network transformations, security measures also had to evolve. With vital personal and business data being shared on computer networks every day, security has become paramount in light of increased network attacks.

A network attack can be defined as any method, process, or means used to maliciously attempt to compromise network security. Network security is the process of preventing network attacks across a given network infrastructure, but the techniques and methods used by the attacker further distinguish whether the attack is an active cyberattack, a passive type attack, or some combination of the two.

There are many layers to consider when addressing network security across an organization. Attacks can happen at any layer in the network security layers model, so your network security hardware, software and policies must be designed to address each area.

Network security typically consists of three different controls. One of those controls, physical controls, are designed to prevent unauthorized personnel from gaining physical access to network components such as routers, cabling cupboards and so on. Controlled access, such as locks, biometric authentication and other devices, is essential in any organization.

Another, technical security controls protect data that is stored on the network or which is in transit across, into or out of the network. Protection is twofold; it needs to protect data and systems from unauthorized personnel, and it also needs to protect against malicious activities from employees.

Then there’s administrative controls, which consist of security policies and processes that control user behavior, including how users are authenticated, their level of access and also how IT staff members implement changes to the infrastructure.
