Cybersecurity shouldn’t be a single piece of technology that improves security. Rather, it should be a layered approach with multiple facets to ensure comprehensive protection.
It’s important to understand what a layered approach consists of. Generally, there are 7 layers of cybersecurity to consider. Below, we explore what these are and why they are important.
The Seven Layers Of Cybersecurity
1. Mission-Critical Assets
This is data that is absolutely critical to protect. Whether businesses would like to admit it or not, they face malicious forces daily. The question is how are leaders dealing with this type of protection? And what measures have they put in place to guard against breaches?
An example of mission-critical assets in the Healthcare industry is Electronic Medical Record (EMR) software. In the financial sector, its customer’s financial records.
2. Data Security
Data security is when there are security controls put in place to protect both the transfer and the storage of data. There has to be a backup security measure in place to prevent the loss of data, This will also require the use of encryption and archiving.
Data security is an important focus for all businesses as a breach of data can have dire consequences.
3. Endpoint Security
This layer of security makes sure that the endpoints of user devices are not exploited by breaches. This includes the protection of mobile devices, desktops, and laptops.
Endpoint security systems enable protection either on a network or in the cloud depending on the needs of a business.
4. Application Security
This involves the security features that control access to an application and that application’s access to your assets. It also includes the internal security of the app itself.
Most of the time, applications are designed with security measures that continue to provide protection when the app is in use.
5. Network Security
This is where security controls are put in place to protect the business’s network. The goal is to prevent unauthorized access to the network.
It is crucial to regularly update all systems on the business network with the necessary security patches, including encryption. It’s always best to disable unused interfaces to further guard against any threats.
6. Perimeter Security
This security layer ensures that both the physical and digital security methods protect a business as a whole. It includes things like firewalls that protect the business network against external forces.
7. The Human Layer
Despite being known as the weakest link in the security chain, the human layer is a very necessary layer. It incorporates management controls and phishing simulations as an example.
These human management controls aim to protect that which is most critical to a business in terms of security. This includes the very real threat that humans, cyber attackers, and malicious users pose to a business.
How To Build A Layered Cybersecurity Approach
Building a layered cybersecurity approach is a gradual and daily process. To start, you need to take stock of your inventory to ascertain the number of devices used, systems as well as firewalls. Then, you can add security where necessary in the different layers.
Yes, the world of work has changed and so has the opportunity for attackers to get their hands on sensitive data.
To protect your business, do regular tests to ensure that your security controls are effective and, most of all, that they work properly.
If you need new security solutions, it’s best to conduct a security analysis to find out what you actually need. Find out whether there are quick wins through which you can achieve compliance with industry regulations.
Building a layered cybersecurity approach will require a strategy to be effective. The reality is that businesses need to be prepared for an attack, meaning you constantly need to test your security measures and adjust where necessary.
In A Nutshell
As a business, you need to have backups and a solid incident response plan that relies on technology, people, and processes to make sure that a layered approach works as best as it possibly can.
The company culture needs to be one that takes security seriously. You need to ensure that you and your staff are knowledgeable about the reality of cyberattacks and the importance of protecting data. The best way to approach cybersecurity is to be proactive instead of reactive when threats or breaches take place.
