Boost Your SMB Security with the Checklist

Posted on Dec 26, 2023 by

Introduction to Checklist

Setting up a reliable and secure network infrastructure is crucial for small businesses to operate efficiently in today's digital landscape. Many small companies have reconfigured their existing networks as they support remote workers, but network security needs to be re-evaluated. Therefore, this checklist provides some key security checks to ensure SMB security. By following these tips, SMBs can establish a robust network foundation that ensures smooth operations and data security.

5 Tips for Cybersecurity

Closely Monitor Traffic

Monitor the traffic coming in and going out of your firewall, and read the reports carefully. Firewalls act as the first line of defense against external threats. These devices protect by monitoring and controlling incoming and outgoing network traffic based on pre-established security rules. Small businesses should invest in a robust firewall solution for SMB cybersecurity that offers features like stateful packet inspection, intrusion prevention systems, and virtual private network (VPN) capabilities. Regularly updating firewall software and maintaining a strong password will further boost network security.

Monitor Traffic

Network Access Control

Network switches play a crucial role in SMB network security by enhancing network segmentation, defending against unauthorized access, facilitating traffic monitoring and analysis, and implementing security policies. By dividing the network into VLANs, switches ensure that compromised segments do not compromise the entire network's security. Advanced security features like ACLs and port security prevent unauthorized access and allow only trusted devices to communicate. Switches with monitoring capabilities enable the detection of security threats through traffic analysis. Furthermore, switches enable the implementation of customized security policies and integration with other security appliances, reinforcing the network's overall security infrastructure. To maintain SMB security, managed switches, unmanaged switches, and smart switches can all be your choices.

Traffic Filtering and Separation

Routers can filter traffic in and out of the network by configuring access control lists (ACLs). ACLs can restrict specific types of traffic based on source IP address, destination IP address, port number, and other conditions. Through traffic filtering, routers can prevent unauthorized access and harmful traffic from entering the network, thereby improving network security. Routers can also divide the network into different subnets or virtual LANs. By segmenting the network, routers can restrict communication between different subnets or VLAN, thereby isolating network resources and sensitive data.

Traffic Filtering and Separation

Network Perimeter Protection

Gateways serve as the entry and exit points between different networks, enabling communication between local networks and external networks or the Internet. Small businesses should configure gateways to ensure seamless connectivity and secure data transmission. Additionally, setting up a virtual LAN can help segregate network traffic, improve performance, and enhance security.

Backup Data Regularly

Regularly back up your important files and data to an external hard drive or cloud storage. In the event of a cyberattack or hardware failure, having a backup ensures you can recover your information without paying ransom or experiencing significant data loss.


Small businesses must prioritize building a reliable and flexible network for SMB security to optimize operations and protect sensitive data. By implementing the tips mentioned in this checklist, which recommends choosing the right switches to analyze traffic, utilizing firewalls for enhanced security, implementing reliable routers, and configuring gateways for seamless connectivity, SMBs can build a strong network foundation. Remember, regular maintenance, updates, and monitoring are critical to maintaining network security and ensuring uninterrupted business operations.
