Here's a table outlining recommended security measures for a small business network, along with the rationale behind each:
| Security Measure | Rationale |
| Firewall (Network Level) | Protects the network from unauthorized access and malicious traffic originating from the internet. Acts as a barrier between the internal network and the external world. |
| Antivirus/Antimalware Software (on all computers) | Detects and removes malware that could compromise individual computers and spread to other systems on the network. |
| Strong Password Policy & MFA | Prevents unauthorized access to user accounts and systems. MFA adds an extra layer of security, making it more difficult for attackers to gain access even if they have a password. |
| Regular Software Updates (Patching) | Addresses known vulnerabilities in software that could be exploited by attackers. Keeps the systems secure against newly discovered threats. |
| Access Control Lists (ACLs) | Limits access to network resources based on user roles and permissions. Prevents unauthorized users from accessing sensitive data. |
| Data Encryption (at rest and in transit) | Protects sensitive data from unauthorized access, even if the network is compromised. Encryption ensures that data is unreadable to attackers. |
| Intrusion Detection System (IDS) | Monitors network traffic for suspicious activity and alerts administrators to potential security breaches. |
| Regular Backups | Provides a way to recover data in the event of a data loss incident, such as a hardware failure or a ransomware attack. |
| Security Awareness Training | Educates users about security threats and best practices, such as recognizing phishing emails and creating strong passwords. Reduces the risk of human error. |
