From Firewalls to Encryption: 5 Basics of Network Security

You wouldn’t consider leaving any documents containing personal data or financial information lying around for anyone to see, as this could have all sorts of implications.

However, if you don’t take network security seriously enough, you leave yourself equally exposed to the prospect of discovering that sensitive data has been stolen or compromised.

Having a clear understanding of how to reduce the risk of being successfully targeted by hackers is absolutely essential. That means knowing the basics of network security.

Here is a look at what you should know about encryption protocols, how firewalls protect you, and some other essential aspects of network security.

Controlling how your data is accessed

If you think about locking a room or a cabinet and restricting access to the key that is basically what you are doing with access control when it comes to network security.

You will often see these measures described as Identity and Access Management (IAM).

This is all about authorizing who accesses certain data and providing a system of accountability by tracking all the logins and actions taken by each user who has been given access.

Access control should be the foundation of your network security protocols.

Understanding authentication types

There are three authentication types widely used at the moment. These are based on password management, software authentication, and personal authorization levels for each individual on the network.

The most common solution is a two-factor authorization. It is also very wise to take advantage of encryption technologies when trying to control the integrity and security of your data.

You must have a firewall

A firewall is designed to monitor and filter any incoming or outgoing traffic on your network.

It is a vital barrier that is designed to keep out harmful attacks by analyzing data from other networks to check if it is safe or not.

Maintaining data privacy

You want to be able to share sensitive data and allow access to authorized users on the network. But you don’t want anyone outside of that circle of trust to see what you are sharing.

It is often suggested that you use a Virtual Private Network (VPN) as it comes with built-in encryption technologies that prevent unauthorized access.

Robust policy management procedures and protocols

As your network grows in size and complexity, you have to ensure that it remains as safe and secure as possible.

That means having an effective policy management in place that outlines all of the security procedures and protocols that have to be adhered to.

Using all of the network security tools at your disposal and creating a policy that outlines how everything will be protected on your network is vital.

If you are unsure how to create a secure network or don’t fully understand how to implement certain aspects of security successfully, such as firewall and encryption protocols, it would be a good idea to consult with a professional network security provider.

Don’t leave anything to chance. Learn how to protect your privacy and data. Use that knowledge to keep everything on your network safe.
