Network Security is a part of Cyber security that cover all the policies, processes, and technologies an organization uses to protect its assets, systems, and network. Regardless of size or sector, businesses must be prepared for dangers such as data loss, unwanted access, and network-based attacks. 

Protecting business-critical infrastructure and assets, reducing the attack surface, and blocking sophisticated threats require network security. Network security solutions employ a layered approach to safeguard networks both inside and externally. Vulnerabilities can be found in various places, such as end-point devices, people, programs, and data pathways. 

New security issues have arisen due to the significant shift to remote employment. Clients and employers must offer access to their data and resources to let remote workers access software and information to do their jobs efficiently.

Top 7 Best Practices for Network Security in 2023 

Here are the best practices to use for Network Security in 2023. 

1. Enable Firewall Protection Possible.  

The best strategy to prevent cyber-attacks on a commercial network is to deploy firewall protection. Unauthorized users are prevented from accessing websites, emails, and other web-based sources of information by the firewall. It is also critical for an individual who works with a company website to have firewall software installed on their local machine. 

2. Network Access with Zero Trust (ZTNA)  

Every access attempt should be verified in a zero-trust security model, which is increasingly being adopted by numerous sectors, standard organizations, and governments. In this framework, nothing on the network can be trusted implicitly. 

Unlike VPN, a zero-trust network access (ZTNA) solution creates micro-perimeters for granular access to apps and data. When users connect to ZTNA, the solution confirms their identity using multi-factor authentication, determines if they are authorized to access the system, and considers the entire security scenario. 

3. Multi-factor Authentication 

Multi-factor authentication adds a layer of security to your data and user accounts. Even if a hacker gets your password, they’ll have to go through a second or third factor of verification, such as a security code, an OTP, a fingerprint, or voice recognition, among other things. It provides an enhanced security method to protect your data and improves access control by allowing you to distinguish between shared account users. 

4. Use Network Address Translation  

NAT is a method of using a single IP address to link many computers to the internet (or any other IP network). NAT works in conjunction with firewalls to add an extra layer of protection to an organization’s internal network. Furthermore, NAT allows an organization to use fewer IP addresses, making it more difficult for attackers to figure out which host they are attacking. 

5. Segmentation of a Network  

When assets within a group share a common function, risk, or role, network segmentation specifies the boundaries between them. Improved security and access control can be achieved by defining more network boundaries. 

6. Controls for Who Has Access  

Make access controls a part of your security plan. These network security elements can assist in identifying users and policies, ensuring that both users and devices have appropriate network access permissions. 

7. Network Security in the Cloud  

It is no longer an issue of whether or not businesses are cloud-based. Instead, it’s a question of how many cloud environments your company has. Keeping up with SD-WAN and SASE, as well as cloud-hosted Firewall-as-a-Service alternatives, is essential for protecting the modern data center.
