1. Back up your data
Back up your business’s data and website. This can help you recover any information you lose if you experience a cyber incident or you have computer issues. It’s essential that you back up your important data and information regularly. Fortunately, backing up doesn’t generally cost much and is easy to do.
It’s a good idea to use multiple back-up methods to help ensure the safety of your important files. A good back up system typically includes:
- daily incremental back-ups to a portable device and/or cloud storage
- end-of-week server back-ups
- quarterly server back-ups
- yearly server back-ups
Regularly check and test that you can restore your data from your back up.
Make it a habit to back up your data to an external drive or portable device like a USB stick. Store portable devices separately offsite, which will give your business a Plan B if the office site is robbed or damaged. Do not leave the devices connected to the computer as they can be infected by a cyber attack.
Alternatively, you can also back up your data through a cloud storage solution. An ideal solution will use encryption when transferring and storing your data, and provides multi-factor authentication for access.
2. Secure your devices and network
Make sure you update your software
Ensure you program your operating system and security software to update automatically. Updates may contain important security upgrades for recent viruses and attacks. Most updates allow you to schedule these updates after business hours, or another more convenient time. Updates fix serious security flaws, so it is important to never ignore update prompts.
Install security software
Install security software on your business computers and devices to help prevent infection. Make sure the software includes anti-virus, anti-spyware and anti-spam filters. Malware or viruses can infect your computers, laptops and mobile devices.
Set up a firewall
A firewall is a piece of software or hardware that sits between your computer and the internet and it acts as the gatekeeper for all incoming and outgoing traffic. Setting up a firewalls protects your business’ internal networks but they also need to be regularly patched in order to do their job. Remember to install the firewall on all your portable business devices, too.
Turn on your spam filters
Use spam filters to reduce the amount of spam and phishing emails that your business receives. Spam emails are usually from a person or company that you don’t know and they usually contain offers too good to be true. Don’t respond, attempt to unsubscribe or call the number in the message. The best thing to do is delete them. Applying a spam filter will help reduce the chance of you or your employees opening a spam or dishonest email by accident.
3. Connect to secure WiFi
Office WiFi networks should be secure, encrypted, and hidden. If you’re working remotely, you can help protect data by using a virtual private network, if your company has one. A VPN is essential when doing work outside of the office or on a business trip. Public WiFi networks can be risky and make your data vulnerable to being intercepted.
4. Ensure you use two-factor authentication (2FA)
Two-factor authentication is a two-step verification security process you need to provide before you can access your account. You use two different authentication factors to verify who you are such as your password and a code sent to your mobile device or your finger print. The two-factor authentication process adds an additional layer of security making it harder for attackers to gain access to your device or online accounts.
5. Manage passwords
Use strong passwords to protect access to your devices that hold important business information. A strong password contains at least 10 characters and includes numbers, symbols, and capital and lowercase letters. Having a password such as ‘123456’, or worse still, ‘password’, is leaving yourself open to being hacked.
If you use the same password for everything and someone gets hold of it, all your accounts could be at risk. Change your passwords regularly and consider using a password manager that securely stores and creates passwords for you.
To avoid a cyber criminal gaining access to your computer or network:
- change all default passwords to new passwords that can’t be easily guessed
- restrict use of accounts with administrative privileges
- restrict access to accounts with administrative privileges
- look at disabling administrative access entirely
Administrative privileges allow someone to undertake higher or more sensitive tasks than normal, such as installing programs or creating other accounts. These will be very different from standard privileges or guest user privileges. Criminals will often seek these privileges to give them greater access and control of your business.
To reduce this risk, create a standard user account with a strong password you can use on a daily basis. Only use accounts with administrative privileges when necessary, limit those who have access and never read emails or use the internet when using an account with administrative privileges.
Employ third-party controls
Limit employee access to customer and client information. If you’re in charge of accessing and using the confidential information of customers, clients and other employees, ensure you implement and follow company rules about how sensitive information is stored and used.
Companies and their employees may also have to monitor third parties, such as consultants or former employees, who have temporary access to the organisation’s computer network. It’s important to restrict third-party access to certain areas and remember to deactivate access when they finish the job.
6. Monitor use of computer equipment and systems
Keep a record of all the computer equipment and software that your business uses. Make sure they are secure to prevent forbidden access.
Remind your employees to be careful about:
- where and how they keep their devices
- using USB sticks or portable hard drives – unknown viruses and other threats could be accidentally transferred from home to your business
Remove any software or equipment that you no longer need, making sure that there isn’t any sensitive information on them when thrown out. If older and unused software or equipment remain part of your business network, it is unlikely they will be updated and may be a backdoor targeted by criminals to attack your business.
Unauthorised access to systems by past employees is a common security issue for business. Immediately remove access (including AUSkey) from people who don’t work for you anymore or if they change roles and no longer require access.
7. Put policies in place to guide your staff
A cyber security policy helps your staff to understand their responsibilities and what is acceptable when they use or share:
- computers and devices
- internet sites
It’s also important to have a strong social media policy. This can set out what type of business information your staff can share online and where. An attacker could tailor a convincing scam around your employee by using the business and personal information they post online.
8. Train your staff to be safe online
Your staff are your business’ most important and last line of defence. It’s important to make sure your staff know about the threats they can face online and the major role they play in keeping your business safe.
Educate them about:
- their computer rights and responsibilities
- their network access and use
- acceptable online practices when using email, work computers and devices
- maintaining good passwords
- fraudulent emails
- reporting suspicious online activity
9. Protect your customers
It’s vital that you keep your customers’ information safe. If you lose their information it will damage your business reputation and you could face legal consequences.
Make sure your business:
- invests in and provides a secure online environment for transactions
- secures any personal customer information that it stores
