In this post we will explain in detail how a small business can secure their network in just 10 mins.
Listed below is the guidance from Code Inclusive IT specialists covering the City of Leeds and the surrounding areas,
Change Default Router & Admin Credentials
Many security breaches occur because default passwords are never changed.
Steps:
Log into your router or firewall admin panel.
Change the administrator password to a strong, unique option.
Disable remote management.
Enable WPA3 or WPA2-AES Wi-Fi Security
Weak Wi-Fi encryption makes it easy for intruders to access your network.
Steps:
Set Wi-Fi security to WPA3 if supported, otherwise WPA2-AES.
Change the Wi-Fi password to a strong, unique passphrase.
Disable WEP or WPA-TKIP.
Turn On Automatic Updates
Unpatched systems are the leading cause of network and system hacks.
Steps:
Enable automatic operating system updates on all PCs and servers.
Update:
Router firmware
Firewall
Key business applications
Enable Multi-Factor Authentication
Credential theft is a major cause of security breaches.
Steps:
Enable MFA on:
Email (Microsoft 365 / Google Workspace)
Remote access or VPN
Admin accounts
Cloud storage
Recommended methods:
Authenticator apps
Hardware security keys
Segment Guest Wi-Fi
Visitors should never have access to the internal business network.
Steps:
Enable a guest Wi-Fi network on the router.
Ensure Guest Network Isolation is switched on.
Configure Firewall
A misconfigured or disabled firewall can compromise network security.
Steps:
Confirm the firewall is enabled on:
Router
All computers
Disable port forwarding unless it is strictly required.
Back Up Critical Data
Having backups dramatically reduces the risk of ransomware.
Steps:
Enable automatic cloud backups (OneDrive, Google Drive, etc.).
Ensure backups are versioned and not directly writeable by ransomware.
