How to Secure a Wide Area Network- Must Know


The wide area network is the most important part of any organization as far as communication goes. Firms such as SD WAN experts ensure that the WAN created is reliable and secure.

However, to ensure that your wide area network is secure, you can put in place some aspects in the installation process. Security is of top priority since it determines the effectiveness of the whole network.

Putting Together a Security Strategy:

The wide area network security strategy ought to place its focus on the risks that the firm faces rather than its current needs.

The mistake of focusing on the needs has been committed by many businesses but it only leads them to be vulnerable. On the other hand, focusing on the risks the firm faces directly addresses the problem in question.

Risk Assessment:

Any network that is operational will be prone to hacks and attempted breaches from hackers and intruders. The two types of intruders one can expect to see on their networks are active and inactive ones.

The active ones will carry out active attacks such as stealing passwords, hijacking the traffic and stopping the workflow. The passive ones will, on the other hand, simply check into the network to see the information they need without active participation.
Securing the network

After doing the above, you will then put in place several measures to keep your WAN safe.

They include:

• Encrypting data; data encrypting makes the data difficult to steal when it is accessed by the wrong party. Data encryption will thus keep your WAN safe and secure and should be a priority, not an option.

• Putting in place storage controls; storage controls may be both soft and physical controls on the systems and include issuing passwords to specific people.

The storage rooms should also be only accessed by specific people to keep them secure. There are many ways of doing this including having access cards, using biometrics (like fingerprints, irises, faces) and others.

• Callback systems; callback or dial-back systems keep the system secure by only allowing specific people to access the network.

• Security keys for public and private uses; these keys also work as ways of authenticity against the people not allowed to access the network in the first place.

• Secure network operating systems; each WAN has an operating system that ensures it works well. However, any problem with this operating system will render the network unusable. If one wants to stay safe, they would rather keep this software safe at all times.

• Firewalls; firewalls keep a system safe by checking on the identity of the users. If an unauthorized party manages to enter the network, they will be restricted in their access to sensitive data. This is only after they have managed to breach the firewall and entered the network. Otherwise, it will keep them at bay.

If these methods are followed well, the security of the wide area network will be guaranteed with the users and the data being secure from hackers.
