The Basics of a Secure Network

The Basics of a Secure Network

Unfortunately, some businesses have had to learn the hard way in order to pay attention to their business’ cybersecurity efforts. These cautionary tales aren’t lost on many business owners, but in some cases, they are still ignored. That’s where we come in. Today, we thought we would go through some basic things that any organization needs to know to keep their business safe. 

Reliably Secure Wireless 

These days, a lot of business is done on a wireless network. When a business sets up its Wi-Fi, they can make some pretty serious mistakes that can cause real problems if they aren’t caught and corrected. Best practices dictate that any business that sets up a wireless network for their business should change their router credentials regularly, ensure that any firewalls have been updated, and create a guest network that is separate from the main Wi-Fi network that can be accessed by employees.

Up-To-Date Antivirus

Antivirus tools are one of the most important cybersecurity tools an organization can have, but only if they are regularly updated with threat definitions that represent the attacks a network would have to confront. The entire point of antivirus (and other anti-malware tools) is to identify and quarantine potentially malicious code, so if it doesn’t have the latest definitions to accomplish this, it will inevitably let malicious code onto the network; a real problem for any business. 

Keeping Firewalls Current

The same goes for firewalls. Security-minded companies set up multiple firewalls between elements of their computing infrastructure. If the firewalls’ threat definitions aren’t up-to-date, they won’t be very good at catching the malicious code that comes in and out of parts of a network. 

Utilizing Password Management

Password management promotes better password practices. It does so by encrypting the numerous passwords that any user has to have in the course of their work. This means a user only has to remember one password instead of dozens, and removes excuses to not create complex passwords for every account. The more complex the passwords are, the more secure the accounts associated with them are. 

Multi-Factor or Two-Factor Authentication

Two-factor authentication or multi-factor authentication (2FA or MFA, respectively) is a useful security addition to any password-fueled account. Instead of gaining access to an account or profile after they enter a username and password, the user is asked to authenticate their password using a code or other method. This can be something as simple as a text message sent to a user’s email all the way to a biometric scan of a user's fingerprint or iris. The idea is to add another layer of security to password-centric accounts, as they are the ones that are most vulnerable to attack.
