What is fundamental IT security?
Fundamental IT security is the basic methods and practices that protect systems, networks and data against harmful attacks. It is the foundation of cybersecurity, and without it your business is exposed to IT risks such as phishing, ransomware, insider threats and unauthorised access, both external and internal. Even small mistakes can have major consequences.
The good news is that the foundation does not have to be complicated. The 7 tips below cover what needs to be in place before you invest in advanced tools. If you want it handled as an ongoing service, see IT security for businesses.
1. Turn on MFA and use strong passwords
Access control and user authentication are the first line of defence. Use strong passwords, multi-factor authentication (MFA) on every account and clear user controls, so employees only have access to what they need. This protects against unauthorised access, where outsiders gain access to sensitive data, systems or information.
2. Keep software and systems updated
Regularly updating software and installing security patches without delay reduces your IT risks. Turn on automatic updates wherever possible, so servers and workstations do not fall behind.
3. Protect with a firewall and endpoint protection
Install and maintain a firewall and modern endpoint protection (antivirus) to protect against malware and unauthorised access. The protection must be kept up to date just like the rest of your systems.
4. Back up following the 3-2-1 rule, and test it
Have a tested backup strategy following the 3-2-1 rule, so you can quickly recover data after a security incident. This matters most with ransomware, where malicious software encrypts your data and demands a ransom for access. A backup that has never been tested with a restore is a hope, not a plan.
5. Train employees to spot attacks
Employees are both a major risk factor and a critical asset. Regular awareness training with phishing tests builds awareness of IT risks such as phishing attacks, where attackers pose as trustworthy to extract personal information. Training also ensures everyone understands their own role, and it reduces the risk of insider threats caused by deliberate or unintentional actions.
6. Write clear security policies, and make security a leadership responsibility
Clear, consistent security policies are central to avoiding security incidents. Policies should cover access control, safe use of email, handling of sensitive data and regular updates.
At the same time, prioritise cybersecurity at leadership level. Leadership attitudes and priorities shape the organisation's overall security posture, and when leadership sets a high bar, the rest of the organisation usually follows.
7. Carry out a risk assessment and write a contingency plan
The foundation is a risk assessment of your systems and data, where you map which ones are business-critical and which threats could realistically hit them.
Finish with a written plan for what you do in case of an outage or attack, so you do not have to improvise when it counts. The plan gives faster recovery after an incident and helps you comply with legislation and regulatory requirements.
FAQ: frequently asked questions about fundamental IT security
Do small businesses also need to prioritise fundamental IT security?
Yes. Small businesses are often targeted by cybercriminals precisely because they can be easier to attack. Fundamental IT security is therefore relevant to every business regardless of size.
Which security measure is most important to start with?
Start broadly, but software updates, strong passwords and employee training are often the most critical places to begin.
What if my business has already been hit by a cyber attack?
If your organisation has already been attacked, first identify the problem and then shut down the active threat. Next, assess and re-establish systems and implement stronger security measures to prevent future incidents.
