How can you implement defense-in-depth in your network security?

This is so important to Identifying and prioritizing assets is crucial for implementing that is defense-in-depth. For example, when classifying sensitive data and assessing risks guide resource allocation for effective protection.

One of the most important aspects in Cybersecurity, is to know what is in one's premises. To implement a defense-in-depth strategy, it is vital to create, maintain and constantly update an organization's inventory. Users, services, computers and equipment need to be recorded and assigned to an employee (if possible). Location of employees & assets, purpose of use and importance to organization are easier to control and monitor properly. By doing so, not only one is able to prioritize and protect accordingly, but is also able to achieve accountability and traceability.

When you segment and isolating a network is crucial because, on average, it takes about 280 days to really identify and contain a data cyber breach. You can use VLANs and firewalls to create network segments, and this will limit the exposure and impact of a breach or cybersecurity incident.

Segmenting network is essential for a defense-in-depth strategy. Utilizing VLANs, firewalls, routers, and VPNs helps create a more secure environment by limiting exposure, enforcing the principle of least privilege, and improving monitoring capabilities. Physical security measures, such as controlled access to server rooms and surveillance systems, add another layer of protection. In the same way, several hurdles will hinder the progress and discourage bad actors. Breaking through several barriers, both digital and physical, takes time and requires extra effort, notably enhancing the overall security of your organization. As cyber threats evolve, effective network division and robust physical security play a crucial role in security

Cyberattacks can be VERY costly. By using a combination of controls and following industry standards, you can significantly reduce the risk and financial impact of security incidents. Stay vigilant out there!

I would say 95% of cyber breaches come from the human error. By educating and training the users, organizations can significantly reduce the risk of falling victim to threats such as phishing and strengthening overall security posture.

It usually take about 197 days to detect a security breach. By using tools and establishing an IR, organizations can detect and respond to security incidents more quickly and AVOID loss associated with data breaches and cyberattacks.

As companies continue to grow and the number of devices, applications, services and users increases, important security layers can be added to strengthen the defense-in-depth strategies including Intrusion detection systems Endpoint detection and response Network segmentation Data loss prevention VPNs Encryption As companies differ, so are their needs. Security professionals are in the best position to decide what works best in their environment as long as it keeps the bad guys out and allows them to sleep with their eyes closed at night!
