What are the types of company networks that need securing?

Securing different types of company networks is essential for comprehensive cybersecurity. Each type of network serves its distinct purpose and has unique security requirements.

A Local Area Network (LAN) typically connects devices within a limited area, such as a single building or campus. Given its localized nature, a LAN is often vulnerable to internal threats, requiring strong access controls, monitoring, and threat detection to prevent unauthorized access and data breaches.

A Wide Area Network (WAN), on the other hand, connects multiple LANs over larger geographical distances. With more potential entry points and exposure to external threats, securing a WAN involves robust encryption, secure tunneling protocols, and comprehensive monitoring to safeguard data as it travels across various locations.

Software-Defined WAN (SD-WAN) is an advanced approach to managing WAN connections that enhances performance and flexibility by utilizing cloud-based technologies. While it offers improved control and efficiency, SD-WAN solutions also require rigorous security measures to protect against vulnerabilities inherent in both traditional and cloud-based communications.

Given that all these networks — LAN, WAN, and SD-WAN — have distinct but critical security considerations and are integral to a company's operations, it is necessary to implement security measures across all types to ensure a secure and resilient infrastructure.
