Network security has become an indispensable element of modern networks. Organizations must thoroughly evaluate their cybersecurity needs. They must assess the efficiency of SD-WAN’s security features to protect sensitive data, proactively identify vulnerabilities, and maintain the resilience of their SD-WAN infrastructure.

SD-WAN for Better Return on Investments and Enhanced Security

SD-WAN enables organizations to transform their network with better Return on Investments by optimizing network performance and enhancing overall productivity. While SD-WAN has many power-packed features for better ROI, one of multiple organizations’ extensively used SD-WAN features during this network transformation journey is migrating from MPLS technology to Internet technology for Edge connectivity. This migration requires the technological capability of seamless aggregation of any connectivity and robust security functionalities in SD-WAN technology to prevent the Edge from cyber-attacks.

Securing an SD-WAN deployment from end to end is vital to safeguard sensitive data and ensure the reliability of network operations. To achieve this, organizations can utilize several security measures, including encrypted traffic, Next-Generation Firewalls (NGFW), Zero Trust Network Access (ZTNA), and blockchain-type data transmission:

SD-WAN encrypts traffic to make sure that sensitive data is not compromised.
SD-WAN utilizes NGFWs that offer advanced threat security, intrusion detection and prevention, web filtering, content filtering, etc.
Zero Trust Network Access (ZTNA) enhances security when used alongside SD-WAN by providing secure, monitored, and enforced access to remote resources, safeguarding against unauthorized access and threats. Only authorized users and devices have the permission to access the network.
SD-WAN provides unmatched security with innovative concepts like Blockchain type of data transmission thereby offering foolproof mechanisms of data packet transmission.

Network Resilience: SD-WAN vs Emerging SASE Solutions for Modern Networks

Earlier, SD-WAN (software-defined wide area network) freed companies from the problems of legacy MPLS services. Though SASE (secure access service edge) has grown in popularity, optimizing traffic management within the network (SD-WAN principle) remains relevant because it directly impacts network efficiency, application performance, and user experience.

The need now is an approach that utilizes SD-WAN to connect locations besides addressing its security and deployment limitations. While SD-WAN principles focus on traffic management, SASE is useful in ensuring comprehensive security across distributed networks, securing remote access, and adapting to the dynamic needs of the modern workforce.

Addressing Core Operational Concerns with SD-WAN and SASE

SD-WAN and SASE collectively address a company’s core operational concerns. SASE, with its Zero Trust Network Access (ZTNA) model, provides branch offices, remote workers, and mobile users, with secure application access. Besides, it eliminates the attack surface by verifying user identities and enforcing strict data access policies. SD-WAN complements this by optimizing application traffic, ensuring seamless access to critical applications and data while efficiently routing traffic to match workflow needs.

SD-WAN and SASE: Key Differences

SD-WAN and SASE benefit organizations in the need to improve their security and network performance.

Key Areas	SASE Benefits	SD-WAN Benefits
Deployment and Architecture	Unified, cloud-native, simplified deployment	Optimized traffic routing for efficiency and not a cloud-centric solution though can provide cloud computing
Security	Comprehensive, built-in security	Security features may require additions
Traffic and Connectivity	Secures traffic from any location	Efficient traffic management within the network
Remote Access	Enables secure remote access	Supports remote access, may need additional components
Required Expertise	Requires expertise in networking and security	Requires less specialized expertise

SD-WAN and SASE serve different networking needs for businesses. The choice between SASE and SD-WAN depends on a company’s specific network requirements and operational priorities.

Business Type	Networking Solution that Best Fits the Needs
Small Businesses/Startups	SD-WAN
Remote Workforces/Cloud-Based Applications	SASE

In today’s rapidly evolving digital landscape, network security and performance have become critical. While SD-WAN can optimize network traffic and streamline deployment, SASE can ensure data integrity and protect the organizational network against evolving threats. Thanks to remote work, SASE has quickly become popular since 2022. By offering a comprehensive approach to optimizing network performance through managed SD-WAN, FatPipe Networks helps organizations achieve seamless connectivity and enhanced efficiency.

Network Security Best Practices

Network security is no longer regarded as an afterthought; it has become an essential element that aids in an organization’s sustainability. While foundational network security best practices establish a solid baseline of security, securing against common threats and vulnerabilities, advanced practices ensure proactive protection and quick incident response.

Foundational network security best practices

Network visibility

Network visibility lets organizations have a better knowledge of the behavior of traffic on their networks. Organizations can implement the awareness to improve the efficiency, security, and performance of those networks.

Utilize policy-based access control

Policy-based access control decreases vulnerabilities and ensures authorized users access resources in a controlled manner.

Implement network segmentation

Network segmentation minimizes security risks by forming a multi-layer attack surface that prevents lateral network attacks. Consequently, even if attackers breach the organization’s first perimeter of defense, they are contained within the network segment they access.

Maintain familiarity with network device types and understand the OSI model

Knowing network device types assists in configuring security measures precisely. It helps in addressing vulnerabilities specific to each device category effectively. OSI model comprises seven functional layers that provide the foundation for communication among computers over networks. Understanding the OSI model assists in pinpointing vulnerabilities, enabling precise security measures across layers, and strengthening network defense comprehensively.

Provide employee training and awareness

Employee training contributes to efficient threat detection and emphasizes the significance of proactive security measures.

Additional network security best practices that should not be overlooked

Know Network Defenses

Imagine this scenario. The IT team of an e-commerce enterprise lacks a thorough understanding of network defenses beyond firewall utilization. There are chances of failing to identify a breach until customers start reporting suspicious activities. Knowing network defenses including intrusion detection systems is important for organizations to form a powerful security framework.

Secure network from insider threats

Traditional cybersecurity strategies generally prioritize defending the network from external forces. However, this can lead to internal blind spots, which may pose the risk of insider threat. Protecting networks from insider threats is essential for organizations to secure against intentional and accidental data breaches.

Use encryption and VPNs

A healthcare organization cannot afford to compromise on confidentiality of patient information just because remote employees access patient records from public Wi-Fi without a VPN, leading to a hacker intercepting their communications. The employees’ data would be encrypted and tunneled securely, preventing unauthorized access and maintaining confidentiality with the availability of a VPN.

Deploy zero trust

Zero trust is not just about user identity, segmentation, and safe access. It encompasses continuous monitoring, strict access controls, and validating every action irrespective of user location. This concept assumes no implicit trust; its underlying principle is “Never trust, but always verify”.

Perform regular data backups and maintain disaster recovery plans

Frequent data backups and disaster recovery plans are essential for network security as they ensure quick recovery from cyber incidents. During a breach or data loss, backups assure data integrity and operational continuity. Disaster recovery plans provide systematic steps in quickly responding to cyber incidents and minimize downtime, data loss, and operational disruptions.
