How to optimize your multilayered cybersecurity posture?

Even though technology and IT support are indispensable to the functioning and sustainability of many businesses, they also bring their share of challenges. Concerns are raised when  it comes to cybersecurity and the statistics are alarming. According to the 2022 report, 2022 Cyberthreat Defense, by CyberEdge Group, 89.9% of Canadian businesses suffered at least one cyberattack within a 12 month period. Fortunately, concrete measures such as numerous levels of cybersecurity (layers)  can be implemented to minimize risks and impacts.

Multilayered security

In order to reduce the threat of cyberattacks, IT security must be applied simultaneously to various domains within a business. The analogy to an onion and its many layers corresponds perfectly to this concept. Monitoring each level makes it possible to customize the protection of digital infrastructure. When configured specifically, the lines of defence guarantee protection that is adapted to various risk profiles. 

Domain 1: personnel

Because of their digital activities, a company’s employees can be both the Achilles’ heel for cybersecurity or the best line of defence. Cybersecurity awareness training, password management and multifactor authentication are three potential solutions to consider for creating a more robust human firewall.

Domain 2: perimeter

By creating a security perimeter to counter potential attacks, businesses reinforce the protections required for entering the network. Firewalls, spam filters, dark Web monitoring and intrusion tests represent additional safety precautions.

Domain 3: network

To protect your IT network, it is considered a wise strategy to implement various tools such as security information and event management (SIEM), security operations centre services, network segmentation and wireless authentication. 

Domain 4: endpoints

Endpoint security involves monitoring and alert services, an integrated service called  ”Endpoint Detection and Response” (EDR), patch management, disk encryption and vulnerability assessment.

Domain 5: data

The best practice for saving data securely is the 3-2-1-1-0 rule: keep 3 different copies of your data, copies on 2 different media, 1 copy off site, 1 copy off line, 0 errors on recovered data.

Domain 6: the company

At this level, it’s important to implement an established action plan so that in the event of an incident your business can continue to operate while limiting the damage. 

In short, a multilayered protection system means that if one layer of defense is compromised, the other layers will provide reinforcement for supplementary protection. This in depth approach will considerably reduce the risk of successful attacks.
