Cybersecurity is like an onion. Seemingly un-special from the outside, onions are usually cast aside as just another ingredient in a delicious dish. But, much like an onion, a robust security system also looks unassuming on the outside – but packs a powerful punch within its many layers.
Like the layers of an onion, a layered approach to security (also known as “multi-level security” or “in-depth security”) is becoming more and more needed as cyber threats become more sophisticated in their attempts to penetrate organization’s networks and security systems.
The idea of a layered approach
Instead of addressing these complex cyber threats with one comprehensive solution, companies use a layered approach to mitigate and defer attacks targeting their essential resources.
The basic idea of creating a layered security system for an organization is to have multiple defences, each capable of warding off an attack should one falter. Particularly so when there are many points of entry for hackers, you need to know that you’ve covered all bases that are prone to attack and data loss.
Of course, it isn’t possible to have a 100% hacker-proof system, nor is there a one-size-fits-all approach. But, with comprehensive security coverage for all of your organization’s devices, networks, applications, and core data, you can rest assured everything is well protected.
Advantages of a layered approach to security
It is a distinct advantage to have a security system of differing levels and barriers of protection. Each layer of security implemented directly minimizes any potential access and makes it much more difficult to infiltrate the system.
This security method emphasizes the importance of having secure computers, servers, networks, and even routers. This also extends into the physical aspects of security, such as educating employees on good security hygiene to further prevent any opportunities.
When implemented correctly, the layered onion approach to cybersecurity can be divided into three objectives: prevention, detection, and response.
Prevention: Of course, one of the best ways to protect your company is by ensuring that attacks don’t happen in the first place. This could be by educating employees, providing proper systems such as VPNs, guest wifi networks, and firewalls.
Detection: If there is an attack, getting it detected quickly by security professionals can help your business stand a better chance. Responding with the appropriate measures can help prevent any further damage or loss. Rapid detection can also allow IT personnel to fill the security gaps that have been discovered.
Response: After detecting a cyber incident, professionals should respond immediately when they’ve located the gaps in the network to ensure no other attacks can happen the same way again.
Security layers to consider
Similar to an onion, many layers protect the very center. While no organization’s approach will be the same, a few layers need to be considered when implementing a multi-level defence against malicious cyber threats.
Physical layer
- As the outermost layer of your cybersecurity onion and your first line of defence, the human aspect of security should be addressed as one of the most critical areas. This encompasses the premises barrier, such as having access points locked, security cameras in control rooms, or even physical ID cards that must be swiped before entering.
Likewise, employees in all positions should be educated on how to stay cyber safe, such as recognizing phishing and creating secure passwords. Regardless of how good your IT infrastructure is, one wrong email download and it could all come crashing down.
Network security layer
- Once your physical location is secured, special attention should be paid to reinforcing your network. You can keep malicious hackers from your computers and servers by first blocking them from accessing your network by configuring impenetrable routers, firewalls, web content filters, and HTTPS inspection. Additionally, ensuring encrypted, remote access through VPNs is an excellent idea so that all employees are safe.
Software protection layer
- Securing your infrastructure by using Malware Protection Software can secure your company’s software by implementing intrusion detection systems, anti-spam tools, virus detection, and encryption tools that help detect and prevent threats.
Data protection layer
- A critical layer you have to consider is what you’re protecting – your company data. It’s imperative to add protections that secure sensitive information from being stolen should someone malicious enter into one of your systems. In addition, important data should always be encrypted and backed up regularly (to avoid losing any information if it was deleted).
Conclusion
Implementing the multi-layered onion approach is the best way to keep your systems secured when protecting the data of your company, employees, and customers. Want to keep your data safe? Contact us today to find out how we can help create a multi-layered defence system for your organization!
