7 Critical Steps for Securing Your Business' Network Infrastructure​

Before the pre-cloud era, the standard corporate network was a closed, micromanaged environment where I.T. controlled every application and device. However, since the proliferation of cloud services and mobile devices permeated the corporate landscape, things have changed. Businesses today utilizing both on-premise and cloud-based apps and users performing their duties on multiple devices causes the traditional firewall—which used to protect all the enterprise I.T. resources in the past—no longer be able to protect every application and device.

 

While no amount of security will ever stop 100% of all attacks, you still can minimize risk of suffering a breach and the fallout from such attacks by taking these few critical steps:

 

Review your applications.

Your network can be infected through the different applications that run in your system. Thus, review your digital applications and monitor them constantly to guarantee their security. If possible, scan your devices regularly for viruses and malware so as not to make your entire infrastructure vulnerable to malicious attacks.

 

Protect your network inside and out.

To avoid the cybersecurity breach, the most important measure to take is to secure your network from the inside out. Tools that monitor how your network is used by employees, and virus and malware protection software are a few examples. There are also other ways to shield your network from both internal and external vulnerabilities. Make use of all of them.

 

Limit user access privileges to the minimum necessary for work.

If three-quarters of insider attacks are malicious, how can your organization prevent such attacks? One solution is to apply a policy of least privilege (POLP) to every user account on the network.

 

Use secure socket layer.

An SSL or Secure Socket Layer is a protocol that establishes security between a web browser (server) and a website. It is to ensure that confidential information travels from one to the other without the risk of it being intercepted by outside parties and remains private. Encrypt your connections with this security protocol for safety measures.

 

Build a firewall.

Although a traditional firewall might not be able to protect your organization fully, it is still the most important measure to be taken in securing your network. After all, a firewall serves as a border control that defines your perimeter and prevents the unauthorized access to your private network—even the attempt comes from inside.

 

Running a network security audit.

A network security audit is a process by which a company can investigate their network security policies to identify any potential deficiencies that might lead to a security compromise/breach. Generally, you can conduct these audits via a third part such as a managed security service provider, or run such audits using an internal cybersecurity team.

 

Conduct cybersecurity awareness training.

The biggest weak link in any organization’s cybersecurity architecture is, usually, the organization’s employees who haven’t undergone cybersecurity awareness training and vulnerable to various threats found online. Cybersecurity awareness training lets them know what the risks are and how to identify some basic phishing attempts.
