- Apply Encryption To Data. End-To-End Encryption (E2EE) ensures that data shared through a network is secure and authorized to workers who can access the data.
- Set Up A Firewall. A firewall is a popular way to protect a company’s network. It filters both incoming and outgoing network traffic based on a company’s security policies and rules.
- Establish A Virtual Private Network (VPN) A virtual private network encrypts Wi-Fi, internet connections, and data transfers in a company’s network. Most VPNs have a built-in kill switch to disconnect hardware in the network if a protected connection is lost.
- Be Consistent With Network Monitoring. Whether traffic errors or vulnerabilities, watching the network is the difference between being unaware of cyberattacks and seeing potential attacks before they happen.

A firewall acts as a barrier between your network and the outside world, as it monitors incoming and outgoing network traffic. Deploying a firewallwill enable your organization to filter and block unauthorized access attempts. By defining strict rulesfor the firewall, you can control the types of traffic allowed into your network, reducing the risk...
One of the simplest ways to enhance network security is by using strong passwords. Weak passwords are vulnerable to brute-force attacks and can be easily cracked by malicious actors. Implement a password policy across your organization that enforces complex passwords containing a combination of uppercase and lowercase letters, numbers, and special ...
In addition to enforcing a strong password policy, organizations should implement 2FA wherever possible. Also known as multifactor authentication (MFA), 2FA provides an extra layer of security by requiring users to provide two forms of identification to access the network. By enabling 2FA or MFA, even if passwords are compromised, unauthorized acce...
Software and firmware updates often contain patches and security fixes that address vulnerabilities in the system. Regularly update all network devices, including routers, switches, firewalls, and servers, with the latest security patches. Additionally, ensure that all software and applications used on networked devices are up to date, as attackers...
When accessing your network remotely or connecting to public Wi-Fi, using a VPN is crucial to secure your data transmission. VPNs encrypt your network traffic, making it difficult for hackers to intercept and decipher sensitive information. Keep in mind that VPNs can come in all shapes, sizes, and security levels. Look at the best VPN service provi...
IDPS solutions monitor network traffic for malicious activities and can detect and prevent unauthorized access attempts or attacks. These systems can provide real-time alerts and take automated actions to mitigate potential security threats. Deploying an IDPS adds an extra layer of defense against network intrusions and helps maintain network integ...
A secure network comprises various components that work together to protect data and systems from unauthorized access and cyber threats. Some of the key components include routers and switches, firewalls, IDPSs, and VPNs.
While following network security best practices and implementing network security tools can enhance the security of your networks, there are still a couple of challenges you should be wary of, such as insider threats, lack of awareness or compliance, budget and resource constraints, and the ever-evolving nature of the cybersecurity landscape.
Securing your network is an ongoing process that requires constant vigilance and adaptation. By following this guide, you can significantly enhance the security of your network and cut down the risk of unauthorized access and data breaches. Remember, network security is a collective responsibility, and taking proactive measures today can help prote...
Nov 15, 2019 · 1. Audit the network and check security controls. Knowledge is essential in maintaining a secure environment. To have an accurate perspective on the security posture of a given enterprise, the IT organization needs to run an audit of the network. By auditing, IT professionals can accomplish the following:
- Amy Larsen Decarlo
The first step to secure a network is to perform a thorough audit to identify the weakness in the network posture and design. Performing a network audit identifies and assesses: Presence of security vulnerabilities. Unused or unnecessary applications. Open ports. Anti-virus/anti-malware and malicious traffic detection software. Backups.
Network security refers to the tools, technologies and processes that protect an organization’s network and critical infrastructure from unauthorized use, cyberattacks, data loss and other security threats.
Regardless of your organization’s needs, there are a few general network protection tips and best practices that you should be sure to follow. Below is a very basic overview of some of the most important, but perhaps underestimated, steps IT professionals should take to ensure network security.
