Network Security Essentials: How to Build A Secure Enterprise Network

In today’s world, network security is crucial for businesses mainly due to the external parties that pose a threat to organizational sensitive data. In the first quarter of 2023, over 6 million data records were exposed. The average cost of a data breach in 2023 was reported to be $4 million, a 15% increase compared to 2020. The global pandemic saw a major increase in cybercrimes. As the technological landscape advances, criminals also advance. Therefore, it is important to build a secure enterprise network. Companies that use network security AI save $2 million compared to companies that do not implement such security automation measures. The need for enterprise network security is critical for protecting the confidentiality of a company’s data, building the company’s integrity, and keeping the company’s work running smoothly. Understanding network security and vulnerabilities is important for businesses as it helps them develop a strategy that effectively mitigates the risk of external threats, protects private and confidential information, and saves time and cost. Moreover, the company’s reputation stays intact as the breaching of customer data and private information poses a threat. Network security is essential for the longevity of businesses and enterprises as it protects them against unauthorized access and cyberattacks. 

Why is Enterprise Networking Security Important?

Enterprise networking requires security due to the existing vulnerabilities it possesses. Some of the common enterprise network security threats include:

Phishing:

One of the most common yet easy way to access a network. Cybercriminals or third parties use it as a form of legitimate communication to deceive the victim into performing actions or sharing sensitive information with the sender. 

Outdated Software:

Older software versions often lack security measures because they are easily accessible. Sensitive information theft and data breaches can occur, so it is better to upgrade the network security in case of such events. 

Unsecured Access Points:

Wireless access points are also vulnerable to external threats like unauthorized access. They are prominent in environments where many users use open Wi-Fi networks, making them easy targets for attackers. 

Distributed Denial-of-Service (DDOS):

DDOS occurs when the perpetrator sends large amounts of traffic to network routers and servers to overload the enterprise network. DDOS can lead to downtime and decreased revenue due to delayed operations.

Key Components of A Secure Enterprise Network

 

Firewalls:

They filter and manage incoming and outgoing traffic. Based on the network security policy, they restrict malicious data packets from entering. By screening out unwanted or harmful packets, they offer protection. Most network routers and switches have embedded firewalls, which can be software or hardware-based. 

Intrusion Detection and Prevent System:

The system helps identify and monitor network traffic for potential attacks. IDPS detects and prevents any attack that indicates malicious behavior or unauthorized access.

Securing Network Access Points:

Implementing strict access control is essential for securing enterprise networking. Measures can include strong password implementation, multi-factor authentication, and regular monitoring of access points for encryption and protection. Updating firmware is essential for enhancing security.

Data Encryption:

This action adds another layer of security for data transmission by transforming the data from a readable format into a protected, unreadable format that the encryption key can decode. It helps the business protect confidential data and prevent unauthorized access. 

Virtual Private Networks:

VPNsoffer security to enterprise networks by creating a secure link between enterprise networks and the employees/users working remotely. VPNs help maintain data privacy and guarantee safe communication by creating tunnels so the data is not intercepted. 

Network Segmentation:

Dividing networks into segments helps protect them by reducing risk and isolating sensitive data and applications for security and compliance. Segmentation also allows for better control over network security policies and better access.

Implementing the following components within the organization will help build a robust enterprise network. However, constantly monitoring and assessing the network for potential vulnerabilities is necessary. 

The following are the best practices for constantly assessing and maintaining a proactive approach to secure enterprise network: 

  1. Regularly audit the software, including operating systems and applications.
  2. A strong security policy is also necessary as it caters to the devices, systems, networks, and operations. 
  3. Regular training sessions can equip employees to identify unusual activity and best security practices.
  4. Implementing a disaster recovery plan is essential for operational and business continuity.

Final Thoughts

Robust enterprise networking is essential for companies looking to scale and expand their operations. Once you implement the best security practices and controls, you are equipped to be secure and protected against external parties. Companies that implement such controls are better trusted, and this helps save costs and time, as incident response can come with a heavy burden. Protecting data, educating employees, and regularly updating security measures and systems help stay competitive, as the systems and people make a strong enterprise networking solution.
