  • Global Substation Security Scan Results: "Breached in 30 Minutes?"“

    Today, I would like to introduce a truly “heart-pounding” report that is directly related not only to the security industry but also to our daily lives. It is the result of an investigation conducted by OMICRON, an Austrian energy security specialist, into over 100 power plants and substations worldwide, and the findings are truly shocking. “As soon as the IDS (Intrusion Detection System) was installed, critical vulnerabilities poured out within just 30 minutes.” Indeed…

  • When an employee's ‘role" changes, security automatically...

    Recent security breaches are primarily caused by human error and failure to adhere to the principle of least privilege. To address this, HPE Aruba Networking's Dynamic Segmentation can strengthen security through role-based access control, reduce human error, and build a zero-trust environment.

  • Role-based zero trust environments

    Until now, our network security has been very static. We controlled traffic and strengthened security by creating security policies based on source IP addresses, destination IP addresses, and ports. However, times have changed. IP addresses are shifting to a DHCP environment, and it is becoming increasingly difficult for IT teams to control user devices, including personal terminals. In this environment, network security using existing security methods…

  • Zero Trust Security in the AI Era

  • What is the role of NAC in the Zero Trust era?

    Ramen with kimchi, pork belly with soju, chicken with beer… While there are various ways to enjoy each and they are delicious on their own, one cannot deny that some pair better and enhance the flavor when eaten together. Similarly, in IT security, Network Access Control and Zero Trust security are excellent individually, but they are even better when used together. Network…

  • Core Features of Zero Trust Network Security

    October is Cyber Security Awareness Month, focusing on protecting individuals and organizations from cybercrime.

Zero Trust [regarding] resources based on roles…

  • Setting up a simulator lab with EVE-NG

    To use the Aruba AOS-CX simulator, you first need to install an emulator such as EVE-NG. If you have not yet installed it, you can install it as a virtual machine using a hypervisor like VMware or Hyper-V. Please refer to the previous post for instructions on how to install it on Hyper-V. Once you have successfully installed EVE-NG, you now need to add an image to set up the virtual lab. In EVE-NG, Aruba products as shown below…

  • Aruba's Portfolio (2)

    Continuing from the previous post, I will continue introducing Aruba's portfolio. Security that secures not only the moment of connection but also during the connection – ClearPass. Security is just as important as wired and wireless network connections. Now that all things are connected to the network, data protection and blocking unauthorized users are crucial. Furthermore, detection and action regarding internal threats occurring without one's knowledge…
