Cybersecurity Best Practices for Australian Tech Startups
Australian tech startups are prime targets for cyberattacks. They often handle sensitive data, possess valuable intellectual property, and may lack the robust security infrastructure of larger organisations. Implementing strong cybersecurity practices from the outset is crucial for protecting your business, your customers, and your future. This article outlines essential cybersecurity tips tailored for Australian tech startups.
1. Implementing Strong Passwords
A strong password is the first line of defence against unauthorised access. Weak or easily guessable passwords are an open invitation for hackers.
Password Complexity
Length: Aim for at least 12 characters, but longer is always better. 16+ characters is ideal.
Variety: Use a mix of uppercase and lowercase letters, numbers, and symbols.
Avoid Personal Information: Never use easily obtainable information like your name, birthdate, pet's name, or address.
No Dictionary Words: Avoid using common words or phrases that can be easily guessed using dictionary attacks.
Password Management
Password Manager: Use a reputable password manager to generate and store strong, unique passwords for all your accounts. Ioy recommends researching and choosing a password manager that suits your needs and budget.
Unique Passwords: Never reuse the same password for multiple accounts. If one account is compromised, all accounts using the same password are at risk.
Regular Updates: Change your passwords regularly, especially for critical accounts like email, banking, and cloud storage. Aim to change them every 90 days, or sooner if you suspect a breach.
Common Mistakes to Avoid
Writing Passwords Down: Never write down your passwords on paper or store them in plain text on your computer.
Sharing Passwords: Never share your passwords with anyone, even colleagues or family members. Use secure methods for sharing access to accounts when necessary.
Using Default Passwords: Always change default passwords on routers, servers, and other devices immediately after installation.
2. Enabling Two-Factor Authentication
Two-factor authentication (2FA) adds an extra layer of security to your accounts by requiring a second form of verification in addition to your password. This makes it significantly harder for attackers to gain access, even if they have your password.
How 2FA Works
2FA typically involves something you know (your password) and something you have (a code sent to your phone, a security key, or a biometric scan).
Types of 2FA
SMS Codes: A code is sent to your phone via SMS. This is a common and convenient method, but it can be vulnerable to SIM swapping attacks.
Authenticator Apps: Apps like Google Authenticator, Authy, or Microsoft Authenticator generate time-based one-time passwords (TOTP). These are more secure than SMS codes.
Hardware Security Keys: Physical devices like YubiKeys provide the strongest level of security. They require physical access to the key to authenticate.
Implementing 2FA
Enable 2FA on All Accounts: Prioritise enabling 2FA on critical accounts like email, banking, cloud storage, and social media.
Choose Strong Authentication Methods: Opt for authenticator apps or hardware security keys over SMS codes whenever possible.
Backup Codes: Store backup codes in a safe place in case you lose access to your primary authentication method.
Scenario
Imagine an employee's email password gets compromised. With 2FA enabled, the attacker would still need access to the employee's phone or security key to log in, preventing a potentially devastating data breach.

3. Regularly Updating Software
Software updates often include security patches that fix vulnerabilities exploited by attackers. Failing to update software regularly leaves your systems vulnerable to known exploits.
Importance of Updates
Security Patches: Updates address security flaws and vulnerabilities that attackers can exploit.
Bug Fixes: Updates improve software stability and performance.
New Features: Updates often include new features and improvements that enhance functionality.
Types of Software to Update
Operating Systems: Update your operating systems (Windows, macOS, Linux) regularly.
Web Browsers: Keep your web browsers (Chrome, Firefox, Safari) up to date.
Applications: Update all your applications, including office suites, antivirus software, and other tools.
Plugins and Extensions: Update your browser plugins and extensions to patch security vulnerabilities.
Update Strategies
Automatic Updates: Enable automatic updates whenever possible. This ensures that updates are installed promptly without requiring manual intervention.
Manual Updates: If automatic updates are not available, check for updates regularly and install them promptly.
Patch Management: Implement a patch management system to automate the process of identifying and deploying security patches across your network.
Common Mistakes to Avoid
Ignoring Update Notifications: Never ignore update notifications. Install updates as soon as they are available.
Delaying Updates: Delaying updates can leave your systems vulnerable to attack. Install updates promptly to minimise risk.
4. Educating Employees About Phishing
Phishing attacks are a common way for attackers to steal credentials, install malware, or trick employees into divulging sensitive information. Educating employees about phishing is crucial for preventing these attacks.
What is Phishing?
Phishing is a type of social engineering attack that uses deceptive emails, websites, or text messages to trick victims into revealing sensitive information.
Types of Phishing Attacks
Email Phishing: Attackers send emails that appear to be from legitimate organisations, such as banks, government agencies, or popular websites.
Spear Phishing: Targeted phishing attacks that focus on specific individuals or organisations.
Whaling: Phishing attacks that target high-profile individuals, such as CEOs or CFOs.
Smishing: Phishing attacks that use SMS text messages.
Vishing: Phishing attacks that use phone calls.
Employee Training
Regular Training: Conduct regular phishing awareness training for all employees. Our services can help you develop and implement a comprehensive cybersecurity training programme.
Simulated Phishing Attacks: Use simulated phishing attacks to test employees' ability to identify and report phishing emails.
Reporting Mechanisms: Establish a clear process for employees to report suspicious emails or websites.
Red Flags
Teach employees to look for these red flags in phishing emails:
Suspicious Sender Address: Check the sender's email address carefully for misspellings or unusual domains.
Generic Greetings: Be wary of emails that use generic greetings like "Dear Customer" or "Dear User."
Urgent Requests: Phishing emails often create a sense of urgency to pressure victims into acting quickly.
Grammatical Errors: Phishing emails often contain grammatical errors or typos.
Suspicious Links: Hover over links before clicking them to see where they lead. Avoid clicking on links in suspicious emails.
5. Backing Up Data Regularly
Data loss can occur due to hardware failure, software bugs, human error, or cyberattacks. Backing up your data regularly is essential for business continuity.
Backup Strategies
3-2-1 Rule: Follow the 3-2-1 backup rule: keep three copies of your data, on two different media, with one copy stored offsite.
Cloud Backups: Use a reputable cloud backup service to store your data offsite. Cloud backups are convenient, reliable, and scalable.
Local Backups: Keep a local backup of your data on an external hard drive or network-attached storage (NAS) device.
Backup Frequency
Daily Backups: Perform daily backups of critical data.
Weekly Backups: Perform weekly backups of less critical data.
Monthly Backups: Perform monthly backups of archival data.
Testing Backups
Regular Testing: Test your backups regularly to ensure that they are working properly and that you can restore your data in the event of a disaster.
Restore Drills: Conduct regular restore drills to practice the process of restoring your data.
Common Mistakes to Avoid
Not Testing Backups: Failing to test your backups is a common mistake. Always test your backups to ensure that they are working properly.
Storing Backups Onsite: Storing all your backups onsite is risky. If your primary site is affected by a disaster, your backups may be lost as well.
6. Developing an Incident Response Plan
An incident response plan outlines the steps you will take in the event of a cybersecurity incident. Having a plan in place can help you minimise the damage and recover quickly.
Key Components of an Incident Response Plan
Identification: Define the types of incidents that your plan covers.
Containment: Outline the steps you will take to contain the incident and prevent it from spreading.
Eradication: Describe how you will eradicate the threat from your systems.
Recovery: Explain how you will recover your systems and data.
Lessons Learned: Document the lessons learned from the incident and use them to improve your security posture.
Incident Response Team
Assemble a Team: Assemble an incident response team consisting of representatives from different departments, such as IT, legal, and communications.
Assign Roles: Assign specific roles and responsibilities to each member of the team.
Communication Plan
Establish a Communication Plan: Develop a communication plan to keep stakeholders informed about the incident.
Internal Communication: Communicate with employees about the incident and provide them with instructions on how to protect themselves.
External Communication: Communicate with customers, partners, and the media as needed.
Regular Review and Updates
Review and Update: Review and update your incident response plan regularly to ensure that it is up to date and effective. You can find frequently asked questions on our website.
