Network security is a broad term that covers different technologies, devices and processes.

Most think of network security as rules and configurations designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies. Every organization, regardless of size, industry or infrastructure, requires a degree of network security solutions in place to protect it from cybercriminals.

Network architecture has become complex and is faced with a threat environment that is always changing with bad actors searching for vulnerabilities found in devices, data, applications, users and locations — just a few minutes of downtime can cause widespread disruption and massive damage to an organization’s bottom line and reputation

Consequently, this complexity of computer network architecture has necessitated the development of many network security management tools and applications to address individual threats as well as regulatory non-compliance.

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.
