In today's dangerous world, cybersecurity isn't just an IT concern – it's a business priority. For IT managers, protecting an organisation’s data, systems and users from cyber threats is a complex and ongoing responsibility. But how exactly do they do it?
From setting up layered defences to building a strong security culture, here's how IT managers keep their organisations safe from cyber threats – and what you should be thinking about if you're in their shoes.
1. Establishing a clear cybersecurity strategy
A robust cybersecurity strategy starts with understanding the organisation's specific risks. IT managers work with stakeholders to assess vulnerabilities, determine what needs protecting most, and create policies tailored to the business’s size, industry and infrastructure.
This typically includes:
-
Risk assessments
-
Data protection policies
-
Incident response plans
-
Compliance with regulations (e.g. GDPR, ISO 27001)
Having a documented, regularly updated strategy ensures everyone knows what to do – and why it matters.
2. Layering defences with multiple technologies
IT managers don’t rely on a single solution. Cybersecurity is most effective when it’s multi-layered:
-
Firewalls block unauthorised access to networks.
-
Antivirus and anti-malware tools detect and remove malicious software.
-
Endpoint protection secures individual devices such as laptops and desktops.
-
Patch management ensures systems are always up to date and protected against known vulnerabilities.
-
Application control prevents unauthorised software from running.
By combining these layers, IT teams can reduce the risk of both external attacks and internal mishaps.
3. Enforcing user access controls
One of the most effective defences? Making sure the right people have the right level of access – and no more.
IT managers implement role-based access, ensuring users only see or modify the data and systems they need for their role. This principle of least privilege helps prevent accidental damage and reduces the risk of insider threats or compromised accounts being misused.
Multi-factor authentication (MFA) adds another important layer, making it harder for attackers to gain access even if credentials are stolen.
4. Keeping systems and software updated
Cybercriminals often exploit known software vulnerabilities – and IT managers know this all too well. That’s why patch management is a key part of their toolkit.
Using tools that automate the rollout of updates and security patches across an organisation ensures critical systems stay protected without relying on manual checks. It also helps IT managers maintain consistency and reduce the chance of human error.
5. Building a culture of security awareness
No matter how good the tech is, people are often the weakest link. That’s why many IT managers focus on building a culture of cybersecurity awareness.
This includes:
-
Regular training sessions
-
Phishing simulations
-
Clear policies on passwords and device usage
-
Reporting procedures for suspicious activity
By turning staff into the first line of defence rather than a liability, organisations can reduce their risk dramatically.
6. Monitoring, auditing and responding
Effective cybersecurity is ongoing. IT managers use tools to continuously monitor network activity, spot anomalies, and respond to threats in real time.
Security Information and Event Management (SIEM) systems and endpoint detection and response (EDR) platforms allow IT teams to:
-
Detect unusual behaviour
-
Identify breaches faster
-
Investigate incidents thoroughly
-
Produce audit trails for compliance
It’s not just about prevention – it’s also about rapid response and recovery.
Staying ahead of evolving threats
Cybersecurity is never 'done'. It requires vigilance, planning and the right mix of tools, policies and people. IT managers are the frontline defenders of business data – and with threats evolving constantly, they must adapt just as quickly.
By combining strategy, layered technology, access control, education and real-time monitoring, IT managers can help ensure their organisations stay safe in an increasingly risky digital world.
