Infrastructure Security

Make your critical infrastructure more resilient

Overview

What is Infrastructure Security ?

Infrastructure Security seeks to protect critical infrastructure, such as network communications, communication centers, server centers, database centers, and IT centers. Infrastructure security limits the vulnerability of these structures and systems to sabotage, terrorism, and contamination.

Strategic and systematic solutioning approach

Network Infrastructure Security needs a holistic approach to ongoing processes and practices to protect the underlying Infrastructure. Therefore, the CISA recommends considering several systems to find implementation methods.

Segment and segregate networks and functions
It requires Particular attention to the layout of the Infrastructure. Segregation and segmentation are effective security mechanisms and restricts potential intruders from propagating into other parts of the Network. Hardware such as routers can be used to separate networks creating boundaries that filter broadcast traffic. These micro-segments can further restrict traffic or even shut down when attacks are detected. Virtual separation is similar in design to physically separating a network with routers with no hardware system.
Limit unnecessary lateral communications
Unfiltered communication between peers could allow intruders to move about freely from computer to computer. Lateral communication enables attackers to establish persistence throughout the Network, and limiting this strategy is required for the security of the Infrastructure.
Harden network devices
Hardening the network devices is a fundamental way to raise network infrastructure security as it adheres to industry standards and best practices regarding network encryption, strong passwords, available services, securing access, protecting routers, backing up configurations, periodically testing security settings, and restricting physical access.
Secure access to infrastructure devices
Administrative privileges allow access to resources that are not widely available and ensure the authenticity of multi-factor authentication (MFA) that manages privileged access.
Perform out-of-band (OoB) network management
The OoB management implements dedicated communications paths to manage network devices remotely. It strengthens network security by separating user traffic from management traffic.
Validate hardware and software integrity
Gray market products threaten IT Infrastructure by allowing a vector for network attack. Illegitimate products get pre-loaded with malicious software, waiting for its introduction into an unsuspecting network. Organizations should regularly check on the integrity of their devices and software.

Why is Network Infrastructure Security important?

The greatest threat to network infrastructure security is malicious applications and hackers that attack and try to take control of the routing infrastructure. The components of Network Infrastructure include all the devices required for network communications, including routers, firewalls, switches, intrusion detection systems (IDS), domain name systems (DNS), and storage systems. Each system presents an entry point for hackers who try to place malware on the targeted Network.

Gateway Risk

In the gateway risk, Hackers gain access to a gateway router and then can modify and monitor the business network system, which can result in denying client services.

Infiltration Risk

After gaining control over the Internal router and switching devices, the hacker can monitor, modify and deny traffic between the hosts inside the Network and exploit the relationship between the hosts and the business.

The hackers can inflict damaging attacks on a network by securing and defending the routing infrastructure should be important in preventing deep system infiltration.

Value for Businesses

Implementing Network infrastructure security provides numerous benefits to the Network of the business. 

Improved resource sharing saves on costs

The Protection resources on the Network are utilized by numerous users without the fear of threat and ultimately reduce the operation cost.

Shared site licenses

The security method ensures cheaper site licensing than machine licensing.

File sharing improves productivity

Safe and secure transfer of files throughout the Internet.

Internal communications are secure

The security system protects internal email and chat systems from cyber attacks.

Compartmentalization and secure files

The User files and data need protection from each other, compared with machines with multiple user platforms.

Data protection

Data and its backup to local servers are simple and secure, protecting vital intellectual property.

Testing

Infrastructure Security strategy to empower your business

Various approaches to network infrastructure security exist, and it is best to adhere to multiple strategies to broaden network defense.

Access Control

Preventing unauthorized users and devices from accessing the Network.

Network Infrastructure

Firewalls: Gatekeeping devices to allow or prevent specific traffic from entering or leaving a network system.

Virtual Private Networks (VPN)

VPNs enable connection encryption and, over the Internet, form a communication tunnel.

Behavioral Analytics

This tool automatically detects unusual network activities from everyday network actions.

Wireless Security

Wireless networks, when compared to hardwired networks, are less secured, and the chances of network infiltration are increasing with the proliferation of new mobile devices and apps.
