Immediate network security steps for business owners. Five critical actions to protect your systems from cyber threats and ensure business continuity.

# Five Things You Should Do Right Now to Protect Your Business Network
Your business network is under constant attack from cybercriminals. Every day you delay implementing proper network security measures increases your risk of devastating data breaches, ransomware attacks, and system failures that could shut down your operations. Here are five critical actions you can take today to significantly improve your network security.
1. Update All Software and Operating Systems Immediately
Outdated software is the #1 vulnerability exploited by cybercriminals. Every delay in applying security updates leaves your business exposed to known threats that attackers are actively exploiting.
Why This is Critical
• Known vulnerabilities - Hackers have detailed maps of unpatched systems
• Automated attacks - Bots continuously scan for vulnerable systems
• Zero-day exploitation - Criminals often know about vulnerabilities before patches exist
• Network propagation - One unpatched system can compromise your entire network
What to Update Right Now
Operating Systems:
• Windows computers - Run Windows Update immediately
• Mac systems - Check for macOS updates in System Settings
• Server operating systems - Apply all security patches
• Mobile devices - Update iOS and Android on business devices
Critical Software:
• Web browsers (Chrome, Firefox, Edge, Safari)
• Adobe products (Reader, Flash if still used)
• Java runtime environment
• Microsoft Office suite
• Antivirus software definitions
Network Equipment:
• Router firmware - Often overlooked but critical
• Switch management software
• Firewall operating systems
• Wireless access point firmware
Implementation Steps
1. Inventory all systems - Create a complete list of devices and software
2. Prioritise critical systems - Update servers and network equipment first
3. Schedule regular updates - Set automatic updates where possible
4. Test in stages - Update non-critical systems first to identify issues
5. Document the process - Track what's been updated and when
2. Change All Default Passwords and Implement Strong Password Policies
Default passwords are publicly available information that hackers use to gain instant access to business systems. Many Australian businesses are still using "admin/admin" or "password123" on critical systems.
Password Vulnerabilities
• Default credentials - Manufacturers' passwords are known to criminals
• Weak passwords - Simple passwords are cracked in minutes
• Password reuse - Same password across multiple systems multiplies risk
• Shared accounts - Multiple people using the same login credentials
• No password changes - Credentials never updated after installation
Immediate Actions Required
Network Equipment:
• Router admin interfaces
• Switch management consoles
• Firewall administration panels
• Wireless network passwords
• Network-attached storage devices
Business Applications:
• Practice management systems
• Accounting software
• Email server administration
• Database management systems
• Cloud service accounts
System Accounts:
• Windows administrator accounts
• Linux root access
• Application service accounts
• Backup system credentials
• Remote access accounts
Strong Password Requirements
Implement these standards immediately:
• Minimum 12 characters - Longer passwords are exponentially harder to crack
• Mixed character types - Upper case, lower case, numbers, and symbols
• No dictionary words - Avoid common words in any language
• Unique passwords - Different password for every system
• Regular changes - Update every 90 days for critical systems
Password Management Solutions
• Business password managers - Tools like Bitwarden or LastPass Business
• Multi-factor authentication - Add second layer of security
• Single sign-on - Reduce password fatigue with integrated systems
• Password generators - Create truly random, strong passwords
3. Configure Your Firewall Properly and Enable Network Monitoring
Many businesses have firewalls but haven't configured them correctly. A misconfigured firewall provides a false sense of security while leaving your network completely exposed.
Common Firewall Mistakes
• Default configurations - Using manufacturer settings without customisation
• All ports open - No restrictions on network traffic
• No monitoring - Firewall logs ignored or disabled
• Outdated rules - Old configurations that don't match current needs
• Bypassed protection - Alternative routes around firewall controls
Essential Firewall Configuration
Inbound Traffic Rules:
• Block all unnecessary incoming connections
• Allow only specific services on designated ports
• Restrict administrative access to specific IP addresses
• Implement geo-blocking for international threats
• Enable intrusion detection and prevention
Outbound Traffic Controls:
• Monitor and control outbound connections
• Block suspicious websites and domains
• Prevent unauthorised data transfers
• Control application internet access
• Monitor for malware communication attempts
Network Segmentation:
• Separate guest networks from business systems
• Isolate critical servers from general user networks
• Create separate VLANs for different departments
• Implement network access controls
• Monitor traffic between network segments
Network Monitoring Implementation
• Traffic analysis - Monitor all network communications
• Anomaly detection - Identify unusual activity patterns
• Bandwidth monitoring - Track data usage and identify problems
• Security event logging - Record all security-related activities
• Real-time alerts - Immediate notification of security incidents
4. Implement Automated Backup Systems with Regular Testing
Backup systems fail when you need them most. Many Australian businesses discover their backups don't work only after suffering data loss. Implementing and testing backup systems today could save your business tomorrow.
Why Backup Failures Happen
• Untested systems - Backups never verified until disaster strikes
• Outdated procedures - Backup configurations not updated
• Storage failures - Backup media fails without detection
• Human error - Manual processes forgotten or done incorrectly
• Incomplete coverage - Critical systems not included in backups
Immediate Backup Implementation
Critical Data Identification:
• Customer and client databases
• Financial records and transactions
• Email communications and archives
• Business documents and contracts
• System configurations and settings
Backup System Configuration:
• 3-2-1 Rule - 3 copies, 2 different media, 1 offsite
• Automated scheduling - Daily backups without human intervention
• Incremental backups - Daily changes with weekly full backups
• Cloud integration - Offsite storage in Australian data centres
• Encryption - Secure backup data against unauthorised access
Backup Testing Procedures:
• Monthly restoration tests - Verify backup integrity
• Full system recovery drills - Practice complete restoration
• Documentation updates - Maintain current recovery procedures
• Performance monitoring - Track backup success rates
• Disaster scenarios - Test different failure situations
Business Continuity Planning
• Recovery time objectives - How quickly must systems be restored?
• Recovery point objectives - How much data loss is acceptable?
• Alternative operations - Manual procedures during system recovery
• Communication plans - Managing stakeholders during disasters
• Vendor relationships - Emergency support contacts and procedures
