Protecting Your Business from Cyber Attacks
In a connected world, a cyber-attack can cripple a business in seconds — and every business is exposed, from a small shop to a factory, through online transactions, banking, email and downloads. Cyber security is simply protection from those attacks: recognise the five categories of attack, then apply seven protection steps.
Executive Summary
recognise, then defendCyber security means protection from cyber attacks. In today's interlinked world, the moment you connect to a network you may not know whether it's secure — and an untrusted network can let a virus in, drain a bank account, or shut a company down. Any business that transacts online, banks online, connects staff to the internet, or downloads from unauthorised sources is at risk. Attacks fall into five categories: malicious (malware), phishing, identity theft, spoofing, and wireless-network attacks. Defend with seven steps: train your team, run a security audit, avoid pirated software, deploy updated and genuine anti-virus, back up data to the cloud, avoid cheap unreliable technology, and write and implement a cyber-security policy. Recognition plus discipline is what keeps a connected business safe.
Look for https & the lock
Before transacting on any site, check the URL shows a lock icon (https) — if it doesn't, the connection isn't secured, so don't transact.
- Never transact on public Wi-Fi.
- Use genuine, patched software.
- Back up; write a policy.
Visual Knowledge Map — five categories of attack
what to recogniseMalware
A shared file with a hidden virus infects your system and network when opened.
Cue: unexpected filesPhishing
A fake look-alike site mimics a real one to capture what you enter.
Cue: no https / lockIdentity theft
Unauthorised use of someone's identity, personal information or data.
Cue: misused identitySpoofing
Someone pretends to be a trusted person or number to gain access or do harm.
Cue: "known" caller, odd askWireless attacks
Open or weak Wi-Fi networks are exploited to reach your data.
Cue: public / unsecured Wi-FiCore Concepts
key definitionsCyber security
Protection of systems and data from cyber attacks.
Attack surface
Every internet connection is a way in — the more connected, the more exposed.
Malware
Malicious code that spreads through an infected file.
Phishing
A fraudulent look-alike site or message that harvests your details.
https / lock icon
Shows the connection is secured; its absence is a warning.
Spoofing
Impersonating a trusted identity, number or sender.
Security patch
An update that closes known holes — missing from pirated software.
Cyber-security policy
Documented rules and training that keep the whole team safe.
Frameworks & Models
are you at risk, seven defencesAre you at risk?
- You transact online with customers.
- You do online banking.
- You or any employee is connected to the internet.
- You download from unauthorised sources.
Safe-transaction essentials
- Check for https + the lock icon before transacting; if absent, don't.
- Never use public Wi-Fi for transactions or sensitive data.
- Use a strong Wi-Fi password at office and home, and keep the network secured.
- Lock down your identity — e.g. use available tools to protect a profile picture from misuse.
Seven steps to protect your business
Train your team
Set rules for email, downloads and using the company network.
Run a security audit
Have a capable cyber-security team audit your risks.
No pirated software
It lacks security patches and leaks data.
Deploy anti-virus
On every system — updated, with genuine keys.
Back up to the cloud
Keep data safe from loss with reputable cloud services.
Avoid cheap tech
Unreliable tools risk failure — quality matters.
Make a policy
Formulate, implement and train on a cyber-security policy.
Why quality matters
If a maker of safety-critical systems cut corners with cheap software and it failed, customers would never trust it again.
Process Flow — securing the business
audit to policyAudit risk
Find the weak points first.
Train the team
Email, downloads, network rules.
Harden systems
Genuine OS + updated anti-virus.
Secure networks
Strong Wi-Fi; avoid public Wi-Fi.
Back up
Copy data to the cloud.
Policy & repeat
Adopt a policy; keep training.

Revision Sheet
layered recall- Cyber security = protection from attacks; everyone connected is exposed.
- Five types: malware, phishing, identity theft, spoofing, wireless.
- Train, audit, patch, anti-virus, back up, quality tech, policy.
- At risk if: you transact/bank online, connect staff to the internet, or download from unauthorised sources.

Frequently Asked Questions
common doubtsWhat is cyber security?
Protection of your systems and data from cyber attacks. Because everything is interlinked, connecting to an insecure network can let in a virus, drain accounts, or shut a company down.
Is my small business really a target?
Yes. Every business is connected — a shop relies on e-commerce, a factory on email, sign-ups and online banking — so size doesn't remove the risk.
How do I spot an unsafe website?
Check the URL for a lock icon, which signifies https (a secured connection). If a site lacks https or the lock, don't transact on it — that's a hallmark of a phishing site.
What is spoofing?
When someone pretends to be a trusted person, number or sender to gain access to your systems or harm your reputation — for example a call that appears to come from a known contact. A clear policy and team awareness help guard against it.
Why avoid pirated or cheap software?
Pirated software has no security patches, so it leaks data, and cheap, unreliable tools risk failure. Licensed software ships with the patches that close known security holes.
What are the most important protections?
Train your team, run a security audit, use genuine and updated anti-virus, back up to the cloud, secure your Wi-Fi, and adopt a written cyber-security policy.

Drop pirated tools, run licensed operating systems, and keep updated anti-virus with genuine keys on every machine.
Secure your Wi-Fi
Use strong passwords at office and home, and never transact or move sensitive data over public Wi-Fi.
Back up to the cloud
Keep copies of important data with a reputable cloud service so a breach or failure can't wipe you out.
Write the policy
Sit with the team to formulate and implement a cyber-security policy, and refresh training regularly.
