A network includes multiple computing devices that are physically or wirelessly connected. Networks use client-server or peer-to-peer architecture in addition to several networking protocols to allow connected systems to communicate with one another.
The growing complexity of enterprise IT infrastructures has led businesses to be more interconnected and operate faster. However, the ease of having accessible data raises vital questions about the security of data and the IT infrastructure overall.
Securing the connected network infrastructure from its core to its perimeter is a component of network security. Network security is often overseen by a network administrator and entails integrating network software and hardware as well as IT security policy.
Although technology is advancing, attackers keep up with it and constantly explore new methods to access sensitive data and harm IT infrastructures. Due to this, it is crucial that companies focus on protecting themselves against disproportionately high-impact network threats.
How the Network Infrastructure Process Works
Network infrastructure security requires continuous methods and processes to protect the underlying infrastructure. These are the following security measures a company deploys depends on:
- Pertinent legal Requirements
- Industry-specific regulations
- The unique network and security requirements
To better understand a network’s demands and vulnerabilities, you can perform a network security audit. In addition, you can use vulnerability assessments or set up a penetration test for an even more in-depth examination.
When a business knows its network requirements, it can implement some (or all) of the best practices. Additionally, companies may rely on universal standards, such as data encryption, robust passwords, top-notch facility security, and data backups.
Importance of Network Infrastructure
The biggest threat to network infrastructure is hackers and malicious applications that attempt to receive access and control routing infrastructure.
Network infrastructure components include devices that are needed for network communication. This includes: routers, firewalls, switches, servers, load balancers, intrusion detection systems (IDS), domain name systems (DNS), and storage systems. Hackers who target these networks try to put malicious software on them so they can easily access these systems through entry points
Since hackers can gain control over networks in many ways, companies should prioritize securing and defending the routing infrastructure and prevent deep system infiltration.
Benefits of Network Infrastructure Security
By implementing a protected network, businesses can confidently control and protect the underlying hardware and software that operate the network. However, strengthening network infrastructure security also has the following additional benefits:
- Internal communications are secure: Internal communications will be protected.
- Data protection: A secure data backup to local servers safeguards crucial intellectual property.
- Better network performance: Network performance and uptime are improved by reliable infrastructure. Additionally, businesses benefit from shorter time-to-market, more predictable expansions, and stable app performance.
- Limited blast radius: Security methods promptly alert the defense team if an intrusion occurs in the network infrastructure. The hostile actor has a shorter window of opportunity to cause harm, and the network will thwart any lateral movement attempts.
- Bandwidth Improvement: Solid control of network bandwidth capacity results from robust network infrastructure security. Quickly determining flow parameters, such as how much bandwidth is being used at any one time and for what reason, helps businesses save money.
Different Types of Network Infrastructure Security
There are a variety of approaches to secure your network infrastructure. Therefore, it is best to adhere to multiple techniques to broaden network defense. Although not every security measure needs to be implemented, businesses should implement numerous approaches to broaden their network infrastructure defense. Some examples include:
- Access Control: Virtually and physically preventing unauthorized users and devices from accessing the network hardware and software.
- Application Security: App-specific security measures an admin places on hardware and software to lock down potential vulnerabilities.
- Firewalls: Gatekeeping devices that control the entry and exit of specified types of traffic from the network.
- Virtual Private Networks (VPN): VPNs safeguard communication over the internet by encrypting connections between endpoints.
- Behavioral Analytics: These tools can automatically identify network behavior that differs from typical utilization.
- Wireless Security: Compared to hardwired networks, wireless networks are less secure, and new mobile apps and gadgets are constantly being developed, opening up new opportunities for network intrusion.
A robust infrastructure lowers operational costs, boosts output, and protects sensitive data from hackers. While no security measure can guarantee that all attack attempts will be thwarted, network infrastructure protection can help you reduce the effects of a cyberattack and ensure that your business is back up and running as soon as feasible.
