An analytical model based on the framework of the Gordon-Loeb Model ([1]) is presented that provides a set of sufficient conditions for information segmentation to lower the total investments in cybersecurity and the expected loss from cybersecurity breaches. A numerical example illustrating the insights gained from the model is also...
微分段是一種網路安全技術,可將資料中心內的不同工作負載相互隔離。透過限制不同工作負載之間的資料流程,並在工作負載層級執行存取控制原則,微分段可讓組織實作更精細的零信任安全性原則。 申請示範 定義微分段? 與所有網路分段技術一樣,微分段的目標是透過定義內部網路邊界將組織的網路分成孤立的區塊。透過監控跨越這些...
網路分段的概念已經存在了一段時間。網路分段最簡單的形式是將組織的內部網路與網際網路的其餘部分隔離。 透過定義此邊界,可以建立以外圍為中心的安全策略,旨在將任何潛在威脅保留在網路外部,同時確保組織的敏感資料保留在內部。然而,組織可以透過在其網路內定義額外的內部邊界來更進一步,這可以提供改進的安全性和存取...
Unlike IT, OT network segmentation must prioritize the safety, reliability, and real-time nature of industrial control systems (ICS) while addressing cybersecurity concerns specific to critical infrastructure. Also, OT networks need ruggedized equipment to operate in harsh environments. Consideraciones ...
Now, the firewall could be for the whole plant or just for the ICS network; both cases occur in practice. But, let’s say that the customer is a bit more advanced in their cybersecurity, and they have a firewall at their process plant level. At the end of every firewall, for ...
“People will begin to see zero trust as a business transformation, not a security program, and they will begin unlocking new technology delivery models because of that,” Simonis said. 3. SASE adoption accelerates Secure access service edge (SASE) adoption is another area that Juniper Networ...
Throughout the industry, there are many models that can be applied to implement network segmentation. These models are designed to protect highly sensitive data in the best way possible for their corresponding field. For example, thePurdue Model of Control Hierarchyconsists of five different zon...
Policy Creation: Most cybersecurity programs do not explicitly call for a segmentation policy. It is usually mentioned indirectly in various topics within the program, which unfortunately does not place sufficient importance or value on it. For example, an access-control policy may call out how an...
In saturated markets, segmentation helps you stand out by aligning your value proposition with the unique needs of your audience. Example: The Department of Defense (DoD) uses segmentation to attract tech-savvy cybersecurity professionals and veterans seeking leadership roles. The campaigns highlight ...
Data segmentationaids in cyber security as well. By restricting the number of network sections that may access your data caches, It creates a barrier around them. With fewer segments having access to data, hackers will have fewer ports of entry to take anything of worth. You lower the risk ...
