Common employee cyber security mistakes

Human error: The biggest threat to small business cyber security.

In 2023, data breaches rose by a record 72%. While technology plays a big role, it's the human element that can make or break small business cyber security. Even with top-notch tech, one wrong move, like reusing passwords or clicking on a dubious link, can leave you exposed.

We’ll look at some of the most common cyber security mistakes, simple ways to avoid them, and what to do if things go wrong.

Cyber security mistakes

Smaller businesses are 3x more likely to be targeted by cybercrime, often because they lack the resources for strong defences. While external attacks might seem like the biggest threat, most breaches start inside the business, caused by mistakes like:

Reusing the same passwords

People using the same password for multiple accounts is convenient, but it’s also a huge risk. If one account gets compromised, cybercriminals can easily access others.

Clicking on dangerous links

What seems like an innocent link can quickly lead to trouble. Whether it’s a phishing email, fake website, or suspicious downloads, one click in the wrong place can open the door to your confidential data.

Opening attachments in phishing scams

Sophisticated phishing emails often come with harmless-looking attachments, but opening one can unleash malware into your system. If people are busy, stressed or distracted, they might click without thinking, and that can be all it takes to set off a breach.

Using weak passwords

We might be more tech-savvy these days, but we still sometimes use weak or placeholder passwords like "9999" or "admin." These easy-to-guess passwords are cybercriminals’ first stop and an open invitation to your critical systems.

Neglecting software updates

It's tempting to hit ‘remind me later’ on software updates, especially when you can’t afford the downtime. But delaying (or forgetting) updates leaves you exposed. These often patch critical vulnerabilities, and cybercriminals will quickly zoom in on any gaps in your defence.

Falling for social engineering scams

Cybercriminals often manipulate people with social engineering. By pretending to be trusted clients, suppliers, or colleagues, they can trick employees into sharing sensitive information or clicking on harmful links.

Phishing awareness and training

Regular phishing simulations can help your team spot red flags like strange email addresses, unexpected attachments, or odd requests for information. Here’s how to implement a phishing defence strategy.

Use multi-factor authentication to help keep attackers out.

Use encrypted platforms for sharing sensitive data, and set clear guidelines on what’s safe to send via email or messaging apps.

Create a culture where security is part of the daily routine.

Regular training, updates on new threats, and creating an environment where employees feel comfortable reporting anything suspicious will help you stay safe. Here’s more on training your staff in cyber security.

Defence strategies

A strong defence strategy isn’t just about avoiding mistakes. It’s having a plan that jumps into action if things go wrong. How you respond can be the difference between a minor issue and a full-blown crisis.

Have a simple, step-by-step incident response plan for dealing with any security situation.

You also need a plan for communicating with clients and any other stakeholders. Be open and honest, especially when sensitive data is involved.

Regular monitoring and security audits ensure your systems, software, and procedures are up to date, and help you identify areas for improvement.

When it comes to cybersecurity for SMEs, your team is your first line of defence. Mistakes happen, but with the right training, a culture of awareness, and a solid back-up plan, you can avoid slip-ups and be better prepared to keep your business safe.
