In response to the escalating demands of corporate networking, global SD-WAN has emerged as the preferred solution for seamlessly connecting various network topologies, including headquarters-branch, headquarters-branch-data center, headquarters-data center, and headquarters-branch-cloud services. Safeguarding the security of data transmission within enterprises has become a pivotal concern.
To ensure data transmission security, global SD-WAN employs a comprehensive strategy encompassing system security and business security.
System Security
System security constitutes the foundation of global SD-WAN solutions, covering aspects such as component communication security, multi-tenancy security, and component integrity. Comprising multiple components, global SD-WAN solutions face potential security threats in both component communication and the components themselves. Implementing a series of security measures is crucial to guarantee the secure and reliable construction and operation of global SD-WAN solutions.
Key measures include identity authentication, data encryption, data validation, and access control. Particularly in Customer Premises Equipment (CPE) scenarios, global SD-WAN solutions adhere to a Zero Trust security philosophy, rigorously verifying the identity information of CPEs to prevent identity spoofing, ensuring that only legitimate and trustworthy CPEs can access the system.
Business Security
Business security pertains to the safety of the business processes supported by global SD-WAN solutions. The deployment of global SD-WAN aims to facilitate business growth, necessitating security considerations for site-to-site interactions, site access to the Internet, and site involvement in cloud-based activities.
To meet the security requirements of business operations, tailored security measures are essential for different business processes. For instance, encryption is vital for site-to-site interactions to ensure the security of data transmitted over the Internet. Meanwhile, for site access to Internet services, global SD-WAN leverages security features provided by CPE, such as next-generation firewalls, ACL filtering, intrusion detection and prevention, and more, offering comprehensive defense against various attacks and intrusion attempts.
It's important to note that these security functions can be configured based on VPNs, allowing for differentiated business security protection for different departments within the same tenant.
Additionally, global SD-WAN solutions support integration with third-party cloud security gateways, leveraging these gateways to secure business traffic accelerating towards public clouds and overseas applications.
By integrating global SD-WAN platforms with leading industry security platforms, IT and security personnel can ensure comprehensive protection of company data. This approach enables every branch to securely and directly access the optimized wide-area network. For in-depth insights into global SD-WAN, feel free to consult Ogcloud!
