6 Useful Tips for Securing WAN Access

Managing a WAN security policy is important to maintaining a high-performance network. The WAN must employ the latest security protocols and be equipped with the right tools to protect sensitive data and applications. WAN security has become increasingly important as more businesses move to the cloud and depend on the internet. Without proper WAN security, your workers, remote sites, and communication tools can become victims of hackers, reducing the overall performance of your business. Even anti-virus programs can be rendered useless if applications are not protected properly.

SD-WAN

Securing a WAN access network is one of the most important aspects of IT security. However, security measures have become complex, and not all solutions are created equal. To get the best security solution, you must find a provider capable of implementing advanced security measures and providing best-in-class security solutions.

Large global organizations need to invest in best-of-breed security from multiple vendors. In addition, they need to protect themselves from threats that can compromise the company’s network. They also need to implement proactive monitoring to keep their network secure.

WAN security

When implementing a wide area network for your business, choosing a security solution is important. The most secure WANs are multi-layered and have multiple layers of security to protect the data inside. In addition, a multi-layered approach is better than a single-layer approach, which leaves an enterprise open to a single point of vulnerability. Generally, SD-WANs that use public internet links are at a disadvantage, especially for international connections, as they’re not known for their security and take a performance hit.

When implementing an SD-WAN solution, businesses should take the time to protect their network against attacks. SD-WAN solutions don’t have built-in security, so all traffic needs to be routed through a comprehensive security stack to avoid vulnerabilities. However, this can be a challenging process.

Encryption

Encryption has a big role to play in securing WAN access. It has become increasingly important as many businesses move to cloud-based technologies. In addition, it is critical for enterprises to protect their workers and remote sites, as well as their communication tools, like VoIP and video conferencing. Without the proper WAN security, these tools can be vulnerable to attack, which can significantly reduce the performance of the business.

WAN encryption protects data in transit and at rest from being intercepted. It also prevents data leakage. It ensures that no unauthorized party can read data from your business’s network. It is recommended that you use encryption whenever possible. You can even use cloud-based data encryption services to encrypt your data before it reaches the cloud.

WAN access list

Creating a WAN access list is essential to securing WAN access. An access list is a sequenced list of statements that can permit or deny routes. Each entry specifies an IP address or a netmask for a network prefix and the forwarding status.

Network devices are hidden from public view

Adding network devices is an important part of securing WAN access. The process should be quick and secure. Most people assumed that network infrastructure gear was stored in a wire closet or rack owned by a service provider. However, an SD-WAN requires a more secure device onboarding process to ensure that only authorized devices are added to the network. One common threat that may pose a security risk is rogue devices masquerading as legitimate network devices.

Network device configuration options

When you set up a network, selecting the best configuration option for your device is important. First, you can configure the device using its IP address, netmask, and Media Access Control (MAC) address. Then, you can edit the parameters of that interface. You can also clear a port or disconnect it. A checkbox also indicates the status of the port. If the port is unsecure, you can toggle its state to secure it.

You can secure a WAN Access device by turning off unnecessary services, testing new patches, and implementing strong password policies. In addition, you can implement access controls to restrict who has access to the device and how many times they can connect at once.
