Network Security Challenges In The Cloud

Network security has become a lot more complex since most organizations have adopted some form of a cloud-based environment. It is estimated that cloud spending will hit $500 billion this year. That’s up almost 20% from last year.

As you move more applications and data to the cloud, the risk of a data breach increases. Three of the biggest threats to your network security are social engineering and human error, lack of access controls, and flat networks.

1. Social Engineering And Human Error

The call is coming from inside the house! Research indicates that 95% of security breaches involve human error. This means that if you are not including security awareness training and phishing testing in your network security plan, you are effectively leaving the door open.

Your employees represent your business in all areas of data supervision, handling your sensitive client information, and keeping your proprietary business intelligence safe. If your employees practice poor data management behaviors, it could cause a significant and costly security breach for your business. It is imperative that your employees understand that they are all targets and susceptible to an attack.

2. Lack Of Network Security Access Controls

Two of the most important tools for keeping your network secure are least privilege access and multi-factor authentication (or MFA).

Least privilege access only gives each user access to the privileges necessary to perform their intended function. For instance, a user in human resources should only be able to access and launch the application(s) necessary to perform their job. They should not be able to perform other functions such as installing new software or accessing financial records.

Multi-factor authentication requires users to present a combination of two or more credentials to verify their identity for login. For example, entering your login credentials and then a 6-digit code sent to your phone as a text message or to your email address.

3. Lack Of Network Segmentation

A single flat network provides cybercriminals with an expansive attack surface. They only need to successfully breach your perimeter once, then they are able to move laterally through your entire network. 

When we segment a network, we partition a physical network into separate, logical sub-networks. We then distinguish the sub-networks and create unique security controls and services for each of them. Dividing your network into isolated sub-networks enables us to isolate an active attack before it can spread over the whole network.
