"Information is power" – it's an age-old saying more relevant than ever. Your data is one of your most valuable assets, not just the business' own sensitive data but also customers' data. This is even more the case today with the 2018 changes to the Privacy Act. Unfortunately, many businesses are rather lax when it comes to using cyber protection keeping this valuable asset safe, even though a serious data breach could bring the business to its knees.
Lock it down with an effective cyber security policy
Empowering employees to protect business data starts with establishing effective cyber awareness programs and having accessible, plain-English cyber security policies. These should start with a focus on password-protecting computers and handheld devices which contain, or can access, business data. In addition to this, a company cyber security policy on staff using their own devices at work is crucial.
At a minimum, a cyber security policy for small businesses should guide staff behaviour and cover effective password management, such as a minimum length and complexity as well as a ban on using the same password for different services. Password managers are worth considering. You should also enable two-factor authentication where available, to offer an extra line of defence for business systems and online services. You may want to also consider having good processes around reviewing who has access to what information in your business (both staff and external suppliers) and making sure that staff who no longer need access no longer do. This is essential cyber security housekeeping often overlooked by many businesses. It would be like not collecting the keys from the previous 10 tenants that leased your rental property.
It's important to tighten up cyber security procedures across the board, not just on a few key systems. Supply chains are critical when working out who has access to your valuable information and how they might be looking after it. Your suppliers should also protect your valuable information - several well-known breaches have been through supply chain vulnerabilities.
Enable your encrypt email settings
An email is like a postcard - it can be intercepted and read in transit. Don’t assume all email is secure email. A growing number of websites enable HTTPS encryption to stop third parties eavesdropping on your online activities. However, staff should always look for the padlock symbol and the 'https://' in a browser's address bar when using services like online banking and webmail.
The encryption settings in your web browser or security software will often warn you if a website looks suspicious, checking for an invalid security certificate or malware embedded in the page. It's easy for your team to develop warning fatigue and simply click OK to every pop-up notification, so it's important to train them to remain vigilant and ask for assistance when in doubt.
Your business should also further enable encryption with the extra protection of a Virtual Private Network when your team members work away from the office. This will help to protect their online activities from prying eyes. It's an especially important security precaution when using public Wi-Fi and Ethernet networks in locations like cafes, airport lounges and hotel rooms.
Be aware of phishing and thinking twice before clicking
A healthy sense of paranoia is one of the best defences when it comes to cyber security. Most businesses rely on email as a key business tool so clicking on links is necessary. But some links come with more than business opportunities.
Cyber criminals looking to steal your valuable information will use a phishing attack as a way of gaining access to your company and your valuable data. Rather than promising something too good to be true, like winning the lottery, most phishing emails often pretend to be something too mundane to be alarming – such as an overdue utility bill or notification of a missed parcel delivery. But always look carefully at the email - - were you expecting a bill? Were you expecting a delivery? Why would the police be emailing an infringement notice to your work email? Could it in face be a scam email?
All staff need to think twice before clicking on links in emails or opening attachments, as these can infect a computer with malicious software designed to steal passwords or perhaps encrypt the computer's hard drive and hold your data to ransom.
Businesses are also vulnerable to targeted "socially engineered" scam emails, which are tailored to trick specific people in your organisation. The "engineered" aspect is that they appear to come from other staff members or people you know. They all have the same intention of getting the recipient to click on the link or do something that will allow them to gain a foothold in your organisation.
These socially engineered scam emails can be harder to detect but the same rules apply: - staff should always approach links and attachments with caution. They should not be afraid to query whether an unusual requests might be a phishing attack, or ring the person or organisation purporting to send the email on their published phone number and check with them.
Building cyber-aware staff is key. Cyber security is as much a human issue as it is a technical issue, so having staff who are aware of the risks and how to manage them can make all the difference in this interconnected world.
