7 layers of cyber security

Cyber security in 2024 is constantly changing and evolving. Businesses and individuals alike are becoming more in-tune to their personal cyber risk and responsibility, but unfortunately, criminals are keeping up with these changing attitudes. New technology, malware types and attack trends mean that applying the correct cyber security layers are more important than ever. In this article, we unravel the intricacies of cyber defence through the lens of the seven essential layers of security.

7 layers of cyber security

Did you know humans are often the weakest link in the cyber security chain?

Do you have a tried and tested plan in place for when things go wrong?

We recommend all organisations get hacked... ethically! This is called a 'red team' exercise.

Do you regularly review who has access to what and why?

Is your technology secure?

Does your Head of IT recognise how many endpoints are on your network?

If you randomly asked an employee where to find your security policies and procedures, could they tell you?

Click the dots to explore the 7 layers of cyber security

1. Policies: the Foundation of Cyber Resilience

At the core of robust cyber security lies a comprehensive set of policies and procedures. Establishing clear guidelines and protocols ensures that every member of your organisation understands their role in safeguarding sensitive information and configuring platforms. This greatly increases the consistency and effectiveness of any IT/OT environment as well as streamlining the operational workings. Think guides on how a new employee should be securely onboarded, policies on what different websites are safe to use internally or how a password should be constructed. Clearly spelling this information out sets the stage for a unified and proactive approach to IT and the security surrounding it.

2. Endpoint Security

Endpoints (devices connected to a network, such as an employee’s mobile device, laptop or workstations) serve as the frontline defence against cyber threats. Antivirus software, encryption, and endpoint detection and response (EDR) solutions play pivotal roles in mitigating attacks at the device level, safeguarding your organisation from malicious infiltrations or unknowing participants in social engineering attacks or malicious website browsing.

3. Perimeter and Network Security

Perimeter and network security involve deploying firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS) and virtual private networks (VPNs). These measures create a robust perimeter that safeguards an organisations assets from external threats. Alongside perimeter security, we must also attend to securing the data in transit within the trusted network. Active and passive network monitoring tools to provide visibility into what is happening on the network, whether it is resources experiencing downtime, to who is sending what and where.

4. Access Control and Zero Trust

When granting access to different business resources, whether physical servers or digital computer data files, it is important to embrace a culture of access control and zero trust. Ask yourself, ‘does colleague X really NEED this shared drive? Or can it be kept to management only?’ Granting the right individuals the right level of access is less about trust of the individual, but more about reducing the risk of an attack. E.g., if the said shared drive in that example is only with higher management (5 profiles) as opposed to the whole organisation (40 profiles), you reduce the risk of an attacker finding that drive by 87.5%! Privileged access management is a vital tool for safeguarding the impact after a breach has happened. Zero trust refers to applying an extra layer of authentication on the authorisation that will ensure those who have access are who they say they are.

5. Risk, Penetration and Vulnerability Assessments

Without testing, how do we know how good we are? Assessments that regularly test the strength of your defences is a crucial step for continuous improvement. These tactics are often referred to as ‘red team’ exercises, where skilled cyber professional (ethical hackers) will attempt to gain access to an organisation to identify security holes from the outside and inside of the network that can be patched and fixed up before a malicious hacker gets there first. 

6. Business Continuity and Disaster Recovery

It is a statistical fact that if you have not been hacked or breached yet, there is a likelihood that it will happen soon. When things go wrong, time is of the essence, and having a tried and tested plan can make a huge difference in your ability to recover. This layer involves creating strategies to minimise downtime, recover data, and resume operations swiftly after a cyber attack. Every moment a company spends down is money lost. Recovery and continuity plans are also not worth anything if they are not regularly tested and set in stone. 

7. The Human Layer: Nurturing Cyber Awareness

Recognising that humans are often the weakest link in the cyber security chain, this layer focuses on education, training and awareness. Training employees on cyber security best practices, social engineering awareness, and fostering a culture of security consciousness strengthens the last line of defence against cyber threats. At the end the day, even if layers 1-6 are secure, without properly educated people there to implement and enforce practices, layers break down in an instant.

As businesses navigate the complex landscape of cyber security solutions, understanding these seven layers are essential for making informed decisions. From policies that establish the groundwork to the human layer that reinforces awareness, each element plays a crucial role in defending against cyber risk. By adopting a holistic approach to cyber security, businesses can create a resilient defence strategy that adapts to the evolving threat landscape, ensuring a secure digital future.
