5 Pillars of Network Security

5 Pillars of Network Security
Your business data is constantly under attack, that’s why you need Cadamier Network Security in Denver to implement the 5 pillars of network security to keep your information safe. Designing multiple layers of hardware and software security can prevent internal and external threats from damaging your computer networks and can contain attacks if they get around your defenses.

Today’s network threats include a host of problems including viruses, spyware, malware, adware, Trojan horses, worms, botnets, hacker attacks, data theft, among others. Cyber thieves are always looking for unpatched software and hardware, weak passwords, lost devices, unsecured wireless networks and websites, potentially unwanted applications, malicious users, and much more.

According to an IT Manager Daily article, there are five fundamentals of network security that you should set as a priority to prevent downtime, address compliance with government regulations, protect your company’s reputation, and reduce your liability. 

Inactive accounts
All inactive accounts that once belonged to contractors or ex-employees should be deleted because cyber hackers can use them to gain access and hide their activity. There is software you can use to clean up inactive accounts if you have a large network with lots of users.

You need to create the strongest passwords possible and keep them safe. A strong password is six characters or more, uses both upper and lower case letters, and includes numbers and symbols. To increase password security, you should change your password every 90 days or so. You can set up a lock-out system where after a number of failed log-in attempts the user will be locked out.

If you have an open network connection it is vulnerable to hackers trying to get onto your network, it is important to secure a VPN by the strongest possible protocols for data encryption and identity authentication. Consider using a multi-factor authentication method. This may include a password and a PIN or a random code created by a key fob authenticator. You should also look into having a firewall that separates the VPN network from the rest of your network.

Patches and Updates
It’s important to keep all devices updated regularly, including network hardware and mobile devices because cyber hackers will target operating systems, software applications, web browsers and browser plug-ins if you haven’t kept patches and updates current. In addition, all computers should be updated automatically and should have the most current software versions.

User Access
You should actively manage your employees’ access privileges to your company’s critical data, making sure they do not have access to sensitive or confidential information outside the scope of their job requirements. If your employee’s job changes, make sure your IT manager restricts their access privileges to reflect only the duties of the new job.

In today’s cyber world, where your network and your critical business information is always under attack, you need to take the appropriate steps to address the 5 pillars of network security so your data is safe. Our experts at Cadamier Network Security in Denver can design hardware and software security to stop cyber threats and counter any breaches.
