In today’s digital landscape, network security isn’t just a concern for large corporations — small businesses are prime targets too. In fact, 43% of cyberattacks target small businesses, and most aren’t prepared.
The good news? You don’t need a massive IT department to secure your network. Follow these 7 simple, practical steps to protect your data, devices, and operations — starting today.
🛠 Step 1: Change Default Router Settings Immediately
Why it matters:
Default usernames and passwords are easy targets for hackers. Your router is the front door to your network — if it’s vulnerable, everything behind it is too.
What to do:
- Log into your router’s admin panel
- Change the default username and password
- Disable remote management unless you need it
- Rename your Wi-Fi SSID (avoid using your business name)
✅ Pro tip: Use a strong passphrase — not just a word with numbers.
🔐 Step 2: Use a Strong, Encrypted Wi-Fi Network
Why it matters:
Open or weak Wi-Fi is a hacker’s playground.
What to do:
- Use WPA3 (or at least WPA2) encryption
- Set up a guest network for visitors — separate from your main business network
- Hide your SSID if you don’t need to broadcast it publicly
- Regularly change Wi-Fi passwords
✅ NodeONE can help set up segmented, secure wireless access for your office.
🧱 Step 3: Install a Business-Grade Firewall
Why it matters:
Firewalls act as a barrier between your internal network and external threats.
What to do:
- Use a hardware firewall at the network perimeter
- Enable intrusion detection and prevention (IDS/IPS)
- Configure firewall rules to block suspicious traffic
- Regularly update firmware
✅ We recommend UTM (Unified Threat Management) devices for all SMBs.
💻 Step 4: Keep All Software and Devices Updated
Why it matters:
Outdated systems have known vulnerabilities that hackers exploit.
What to do:
- Enable automatic updates for operating systems and software
- Regularly patch firmware on routers, switches, and firewalls
- Use a central patch management tool for efficiency
✅ A managed IT service like NodeONE handles all updates and patching for you.
🔎 Step 5: Set Up Network Monitoring
Why it matters:
If you don’t monitor your network, you won’t know when something goes wrong.
What to do:
- Use a network monitoring tool to track activity
- Set alerts for unusual traffic patterns or login attempts
- Review logs weekly (or automate it with your MSP)
✅ We offer 24/7 remote monitoring and alerts as part of our managed IT plans.
👤 Step 6: Implement Access Control and User Permissions
Why it matters:
Not everyone needs access to everything — limit the damage a breach can cause.
What to do:
- Set up user roles and permissions (least privilege model)
- Use multi-factor authentication (MFA) wherever possible
- Create unique logins — never share accounts
- Immediately remove access for ex-employees
✅ We can help audit your user access and enforce secure policies.
🧰 Step 7: Backup Your Data — Offsite and Often
Why it matters:
Even the most secure network can be breached. Backups are your last line of defense.
What to do:
- Use automated, daily backups
- Store backups off-site or in the cloud
- Test backups monthly to ensure data can be restored
- Encrypt backup data for added protection
✅ NodeONE offers fully managed, encrypted cloud backups with fast recovery options.
🔒 Bonus Tip: Train Your Team
Most breaches happen because of human error — not technical failure.
What to cover in employee training:
- How to spot phishing emails
- Safe browsing habits
- Password management best practices
- What to do in case of a suspected breach
