Top 5 Cyber Security Tips to Protect
Your Melbourne Business in 2026

Multi-Factor Authentication (MFA)

Multi-factor authentication requires users to verify their identity using a second method, typically a code sent to their phone or generated by an app, in addition to their password. Even if an attacker steals or guesses a staff member's password, they can't access the account without the second factor.

MFA is the single most effective control against credential-based attacks, which account for a significant proportion of all business breaches. Priority targets for MFA deployment include:

• Microsoft 365 and Google Workspace, email compromise is the most common entry point for business fraud
• Remote access systems, VPN, Remote Desktop (RDP) and any remote working tools
• Cloud platforms, Azure, AWS and any business-critical web applications
• Financial and accounting systems, Xero, MYOB, banking portals

Microsoft Authenticator, Google Authenticator and hardware keys (e.g. YubiKey) are all suitable options. BITS can help deploy MFA across your entire Microsoft 365 environment as part of our managed IT service, including conditional access policies that enforce MFA consistently.

Difficulty: Low

Patch Management

A significant proportion of successful cyber attacks exploit known vulnerabilities for which a patch already exists. Attackers actively scan for unpatched systems because they know many businesses are weeks or months behind on updates.

Effective patch management covers:

• Operating systems, Windows and macOS updates should be applied within two weeks of release (within 48 hours for critical security patches)
• Applications, web browsers, Office, Adobe products and any third-party software
• Network devices, routers, firewalls and switches all receive firmware updates that address security vulnerabilities
• Mobile devices, iOS and Android updates should be applied promptly, especially for company-owned or BYOD devices accessing business data

Patch management is a core component of the ACSC's Essential 8 framework, and is one of the most impactful controls for reducing your attack surface. BITS automates patch management for all managed clients, ensuring no critical update is missed.

Difficulty: Low (when managed)

Security Awareness Training

Your staff are involved in the vast majority of successful cyber attacks, not because they're careless, but because phishing attacks are sophisticated, personalised and increasingly difficult to detect. A single click on a malicious link or attachment can give an attacker full access to your environment.

Effective security awareness training includes:

• Simulated phishing campaigns, send realistic (fake) phishing emails to your staff and track who clicks. Use failures as targeted training opportunities, not punishments.
• Regular short-form training, 5–10 minute modules covering current threats work better than annual all-day sessions
• Clear reporting procedures, staff should know exactly what to do when they receive a suspicious email, and feel comfortable reporting it without embarrassment
• Business email compromise (BEC) awareness, train staff to verify requests for payments or data transfers by phone, especially those that appear to come from executives or suppliers

When combined with technical controls like email filtering and anti-phishing tools, a security-aware workforce becomes your strongest layer of defence. BITS includes security awareness training as part of our managed cyber security service.

Backup & Disaster Recovery

Ransomware, malicious software that encrypts your files and demands payment for the decryption key, remains one of the most financially devastating threats facing Melbourne businesses. The only reliable defence against ransomware is a tested, isolated backup that attackers can't reach.

A solid backup strategy follows the 3-2-1 rule:

• 3 copies of your data
• 2 different storage media types
• 1 copy stored offsite (or in an air-gapped cloud environment that ransomware can't encrypt)

Just as importantly, backups must be tested. An untested backup is a false sense of security. Many businesses discover their backups are incomplete, corrupted or unrestorable only when they actually need them, the worst possible moment.

Your backup plan should also define your Recovery Time Objective (RTO), how long your business can survive without access to data, and your Recovery Point Objective (RPO), how much data loss is acceptable. BITS monitors backup health and tests restore procedures for all managed IT clients.

Difficulty: Medium

Endpoint Detection & Response (EDR)

Basic antivirus software, even well-known consumer brands, is no longer sufficient to protect a business environment. Modern threats including fileless malware, living-off-the-land attacks and zero-day exploits routinely bypass signature-based antivirus entirely.

Business-grade Endpoint Detection and Response (EDR) goes far beyond antivirus. EDR tools monitor endpoint behaviour continuously, detect anomalies that indicate an attack in progress, and can automatically isolate an infected device to prevent lateral movement across your network, even for threats with no known signature.

Key differences between basic antivirus and EDR:

• Antivirus matches known malware signatures. EDR detects suspicious behaviour regardless of whether the threat is known.
• EDR provides full visibility into what happened on a device, enabling proper incident investigation and response.
• EDR can be managed centrally and monitored by a Security Operations Centre (SOC), so threats are detected and contained around the clock, not just during business hours.

BITS deploys and manages EDR across all managed cyber security clients, integrated with our 24/7 SOC monitoring for continuous threat detection and response. This is a key component of the ACSC's Essential 8 framework under Application Control and Patch Applications.
