Cyber Security Basics Every Employee Should Know

Most successful attacks on organisations do not defeat any technology. They persuade a person. Someone clicks a link, reuses a password, or approves a payment because an email looked like it came from the boss. Which means basic security awareness is not an IT specialism — it is part of everyone's job.

Phishing: what to look for

Phishing remains the most common way in, and modern attempts are well written — the old advice about spotting bad spelling is out of date. Look instead for the shape of the request:

• Urgency plus secrecy. "Do this now and don't discuss it" is the signature of fraud, not of management.
• A change of payment details arriving by email. Always verify by phone, using a number you already had.
• A login page reached from a link. Navigate to the site yourself instead.
• An unexpected attachment, particularly one that asks you to enable content.

The safest habit is procedural rather than technical: for anything involving money or credentials, verify through a second channel you chose.

Passwords: three rules that replace all the old advice

Forget forced monthly changes and cryptic substitutions — current guidance has moved on. What matters now:

1. Length over complexity. Three or four random words beat P@ssw0rd1 comfortably.
2. Never reuse. Reuse is what turns one company's breach into your problem everywhere else.
3. Use a password manager. It is the only realistic way to keep dozens of unique passwords.

And turn on two-factor authentication wherever it is offered. An app-based code or a hardware key is significantly stronger than SMS, which can be intercepted by SIM swapping.

Your devices

Install updates promptly — most exploited flaws are ones with a fix already available. Lock your screen when you step away. Be careful with public Wi-Fi for anything sensitive, and never plug in a USB stick you did not buy.

Data protection is part of security

In the UK, mishandling personal data is a legal matter as well as a security one. The practical version for most staff: collect only what you need, share it only with people who need it, do not move it onto personal devices or accounts, and report suspected breaches immediately rather than hoping they go unnoticed. Delay is what turns a small incident into a reportable one.

If you think you have made a mistake

Report it straight away. Every security professional will tell you the same thing: the damage from a clicked link is usually containable, while the damage from six hours of embarrassed silence often is not. Organisations that punish reporting end up with staff who hide incidents — which is precisely how small problems become expensive ones.

Frequently asked questions

Is antivirus software enough?

No. It helps with known malware but does nothing about a convincing email asking you to change bank details. Human judgement covers the gap that software cannot.

How often should staff have security training?

Annually as a baseline, with short refreshers when new threats appear. Awareness decays quickly, and attack patterns change.

What is the single highest-value change?

Two-factor authentication on email. Email is the account that can reset all the others, so protecting it protects everything downstream.
