Seven Layers of Defense for Small and Medium Business Networks

Posted by Bruce Waite | May 23, 2018 11:17:30 AM

Over the last several years, the threats to business networks in terms of hacking (denial of service attacks), malware (keyloggers and password stealers), ransomware (WannaCry, Petra, CryptoLocker) and viruses in general have grown exponentially.  And the recent introduction of Spear Phishing, targeted emails from what appear to be trusted sources, make it harder and harder for business to protect their networks and data. 

There is no 100% guarantee of being immune to these attacks.  But by implementing seven common security practices, you will have a much more secure network and dramatically improve your ability to recover if you do become a victim of an attack. 


Seven Common Security Practices. Have you implemented them all?

  1. Anti-Virus Software
    Install Anti-Virus software on all PC’s and Servers and make sure the local software is regularly updated and your subscription to ongoing virus definition updates are paid for.  This provides the ability to catch and quarantine some viruses before they launch.
  2. Email Spam and Malware Filter
    Ensure you have Spam and Malware Filtering with your email service.  This will reduce threats that could reach your email inbox.
  3. Frequent Windows Patching
    Ensure that you have regularly scheduled Installation of new Windows Updates and Security Patches on both servers and PCs throughout your organization.
  4. Image Based Backup System with Off-site
    Have an image based backup system that are tested and confirmed functional on a regular basis and an off-site copy of your data every day.
  5. Commercial Grade Firewall
    A business of any size should have a commercial grade firewall with advanced security features and valid subscriptions for support, firmware updates and express warranty exchange.  Plus, firmware and operating system updates should be installed regularly.
  6. Sanitized DNS
    Sanitized DNS services monitoring inbound and outbound traffic on your network to/from the Internet.  Its intelligent filters can block your users from clicking through links in emails to unsecure sites and downloading malware or ransomware.
  7. Good User Rights Policies and Employee Education
    Ensure that passwords must meet a certain minimum and be changed from time to time.  Ensure that employees only have access to files and folders that their job requires (ie. can your shipping staff see the HR files?).  Implement some form of user education around cyber security (i.e. don’t click on unknown links in emails or open attachments).


Is your network as secure as it could be?

As noted above, there is no single safeguard.  But by implementing the various layers of security provided by different applications and hardware, you can significantly reduce your risks.   If you know that you have implemented each of the seven common security practices and are keeping them current, you are ahead of the pack.
