Ensuring Network Security with SD-WAN: Strategies and Considerations

Building Advanced, Secure System Networks with SD-WAN

With business IT networks becoming more complex and spread out over wider areas with more remote working, the threat from cyber-attacks and the potential cost of neglecting network security is rising at the same time. In response, many businesses have adapted their networks with SD-WAN, which offers productivity benefits to busy IT networks and also brings next-generation security to keep complex, global networks secure.

 

The Increasing Threat of Cyber Attacks

More than a third of enterprise businesses have reported falling victim to an attempted cyber breach in 2023. Cyber-attacks are becoming increasingly more sophisticated, with criminals attacking networks directly and targeting employees through phishing scams and similar attacks. The consequences of a successful cyber attack can be devastating from both a financial and reputational perspective.

This is especially true considering the huge fines attached to data regulations, such as GDPR. Companies whose customer data has fallen victim to cyber criminals will have to deal with a lack of trust from customers, following the attack. The threat posed by cyber criminals is realy, so it is critical for any business to have robust network security in place to safeguard valuable commercial and customer data, and to maintain business continuity.

The Role of Network Security in Protecting Data

Network security plays a central role in protecting data from unauthorised access, corruption and destruction. It includes methods and security features like firewalls, intrusion detection and prevention systems, virtual private networks (VPNs), secure access controls and network segmentation to ensure only authorised personnel have access to certain areas of the network. By implementing network security measures, organisations can reduce the risk of data breaches, ensuring the confidentiality of their information.

The Cost of Neglecting Network Security

A successful cyber attack can result in significant financial losses, as organisations may face data recovery costs, legal liabilities, and reputational damage.  We’ve already mentioned the costs associated with regulations like GDPR, which can be as high as €10m or 2% of a company’s global turnover – whichever is highest.

Depending on the size of the business, these fines and reputational damage can put its future in jeopardy. Then there’s factoring in the recovery process for lost data or corrupted servers, which can be time-consuming and disruptive, leading to lost productivity. Investing in network security is not only a proactive measure but also a cost-effective approach to safeguarding business assets.

How SD-WAN Enhances Network Security

The Security Features of SD-WAN

SD-WAN systems are designed with security in mind with features that strengthen network security. These include encryption, which protects data in transit and secure network segmentation, which isolates critical systems from potential threats. This means that, in the event a cyberattack breaches part of the system, it won’t be able to access any other part of the network.

SD-WAN also incorporates next-generation firewalls and intrusion prevention systems to detect and mitigate network attacks in real-time. These features automatically scan and monitor activity over the network and alert to suspicious activity such as a sudden increase in bandwidth usage, or an unrecognised IP address or device attempting to access the network. In the future, SD-WAN will likely incorporate more advanced AI and machine learning technology, allowing it to ‘learn’ over time and become more effective at proactive security.

How SD-WAN Protects Against Common Network Threats

SD-WAN enhances network security by using advanced threat intelligence capabilities. These systems analyse network traffic patterns, identify anomalies, and respond to potential threats in real time. By continuously monitoring the network, SD-WAN can detect and prevent Distributed Denial of Service (DDoS) attacks, malware infections, and other common network attacks.

This proactive approach to security is more effective, as it can prevent escalations of attacks before they happen. By contrast, traditional IT security has been designed to understand what happened after an attack and to plug the gaps following a breach – by which point it’s too late.

Key Considerations When Implementing SD-WAN for Network Security

Assessing Your Current Network Infrastructure

This assessment will identify risks, vulnerabilities or limitations in your network which could impact the effectiveness of deploying SD-WAN. By understanding your network’s strengths and weaknesses, you can make informed decisions and tailor the SD-WAN solution to your specific needs.

Choosing the Right SD-WAN Solution

Not all SD-WAN solutions are created equal. Consider factors such as vendor reputation, scalability, ease of deployment, and security features when selecting an SD-WAN solution. For example, if you have a global network and thousands of users, advanced security and threat detection could be essential to more effectively manage activity and flag suspicious activity.

Protecting Advanced Network Management with Advanced Security

SD-WAN provides enhanced network security, offering advanced features and capabilities that protect against an ever-evolving threat landscape. By understanding the significance of network security, and considering key implementation considerations, organisations can secure their network effectively. Implementing SD-WAN as part of a comprehensive network security strategy proactively defends against cyber threats and safeguards data.
