Define Network and Infrastructure Security to Protect Critical Business Assets

By Megan Guth and Kevin Jacobs

Sound network and infrastructure security solutions are vital to the daily operation of your business. They protect data confidentiality and integrity while ensuring resource availability to meet customer demands and expectations.

What Is Network and Infrastructure Security?

Network and infrastructure security refers to the protection of all elements within a networking environment. This includes securing network resources such as hardware, software, systems, and devices that enable communications between users, services, and applications.

Why Does It Matter?

Network and IT infrastructure are the backbones of most businesses. The security of these environments is typically the first line of defense against cyber-attacks. Sound network security prevents downtime or disruption that can cause unnecessary IT costs, loss of business revenue, and damage to customer satisfaction.

In addition to business disruption, unauthorized access to network resources can result in theft of customer data and critical business information—a problem that can be prevented or reduced with the right security protocols in place. As networks continue to grow and become more complex, vulnerabilities grow along with it. Network and infrastructure security solutions are crucial aspects of cybersecurity.

What Can You Do About It?

There are several approaches you can take to secure your network and infrastructure. First, secure identity, which defines what users, systems, applications, and services can have access to network resources. Second, consider securing the systems themselves and securing the communication between those devices. Third, secure the data that resides within the systems when at rest and in transit.

How Do You Secure Your Network and Infrastructure?

Here’s a look at the most common solutions and how they work:

Next-Generation Firewall — A deep-packet inspection firewall that goes beyond port/protocol inspection and blocking to include application-level inspection, intrusion prevention, and cloud-delivered threat intelligence.

Network Access Control (NAC) — A solution that helps organizations control access to their networks and proactively defend their entire network perimeter. This includes both physical infrastructure and cloud-based systems, seeking to stop attacks before they become a reality.

Network Detection & Response (NDR) — A solution that detects security threats on enterprise networks by analyzing network traffic with advanced analytics, machine learning, and anomaly detection.

DDoS Mitigation — A product or a service used to detect and mitigate DDoS attacks. A DDoS attack is an attempt to deny users a service by overwhelming the infrastructure on which they are hosted.

Deception — A process where technology is used to prevent cybercriminals who have managed to infiltrate a network from doing any significant damage. The technology aims to deceive cybercriminals by generating deception decoys that mimic legitimate technology assets throughout the system’s infrastructure.

Microsegmentation — A security strategy used to realize the Zero Trust approach to information systems security management. Zero Trust is especially relevant in the deployment of virtualized environments and containers in cloud environments. It enables fine-grained security policies to be assigned to data center applications down to the workload level.

DNS, DHCP AND IPAM (DDI) — A suite of tools that enable end-to-end planning, deploying, managing, and monitoring of your IP address infrastructure.
