Sie verwalten ein Netzwerk mit sensiblen Daten. Wie können Sie die Sicherheit gewährleisten, ohne das Netzwerk zu verlangsamen?

To secure a network with sensitive data without slowing it down, I would use a balanced approach. Deploying next-generation firewalls and intrusion prevention systems ensures advanced threat protection with minimal latency. Prioritizing traffic for critical applications and using network segmentation to isolate sensitive data helps reduce the attack surface. I would implement optimized encryption protocols and regularly monitor network performance to maintain speed. Additionally, utilizing cloud-based security solutions can offload processing, ensuring the on-premise network remains agile while still protecting sensitive information.

Implement Multi-Layered Security: Use a combination of security measures such as firewalls, intrusion detection systems (IDS), and encryption. Layered defenses protect sensitive data from various angles while minimizing impact on network performance. Optimize Security Solutions: Choose security solutions designed to have minimal performance impact. Use tools that provide real-time protection without causing significant latency or bandwidth issues.

Para que el dato sea confidencial, solo debería de verlo la persona con autorización para ello, y esto incluye que alguien que tiene acceso lo pueda filtrar a alguien q no lo debería de tener. Es por ello que ademas de los mecanismos descritos, se debería de implementar una solucion DLP con una lista linterna bien definida para los accesos y datos permitidos para su transmisión. De igual forma, de forma crítica, cifra y desconfiar de cualquiera que se conecte, requerido para ello una solución de NAC + ZeroTrust que imponga varias capas de defensa para el acceso externo.

Many organizations have MPLS links between their offices. Something important missed here is those MPLS links are provided by third party service providers and they are usually not encrypted. While this data on the move is still on 'semi' private circuit, the provider still has visibility which can breach some security compliance requirements, especially in the regulated domains. Make sure traffic on MPLS links is also encrypted.

Keeping types of data or data from different departments segregated can easily aid in security without affecting day to day performance.

Network segmentation based on users' functions or information access needs is an efficient way to implement security controls for sensitive information without compromising performance. One of the main benefits is that it reduces the number of users with access to that information, making it easier to identify, mitigate, or review any potential security incidents if they occur. Similarly, if regulatory compliance is required, segmentation also helps reduce the number of devices or users that need to be included within the scope of such compliance, significantly decreasing the effort needed to meet regulatory requirements.

Tools have since advanced from VLANs and ACLs. Micro-segmentation can be leveraged by use of products like Cisco ACI or VMWare NSX. It can also be easily leveraged on cloud platforms. On top of that, firewalls these days support multizone configuration. It is not anymore Untrusted, trusted and DMZ kind of architecture. You define zones keeping security in mind. Isolation and segmentation helps keeping the boundaries alive and applying better controls.
