Perimeter security is no longer the best option for corporate IT departments. Requires a more flexible framework that focuses on users, devices and services. The concept of zero trust was created to obtain current and future information technology security threats by operating under the presumption that no person, device or service should be trusted inside or outside the corporate network.
Implementing the five principles of Zero optimism The companies listed below will help you make full use of this security model, but an ID security team cannot enforce zero trust and then walk away. Each principle though is that the cycles should follow a continuous process pattern – and then it starts all over again. A zero-confidence model must continue to be developed to accommodate how business processes, goals, technologies and threats change.
Here are five principles of zero trust that will ensure the successful adoption of this concept in long-term IT strategy.
1. Know your protective surface
A company’s IT security surface covers all users, devices, data and services. There must also be transport mechanisms on the protective surface – the network – where important company data travels. One of the main reasons why zero-confidence structures have become so popular is that the security surface for most businesses is now beyond the protections of a corporate lawn. Traditional perimeter or edge protection tools are no longer the same because many data no longer pass through the corporate network.
The change in data flows forces cyber security tools to push out Beyond the edge of the network Get as close as possible with applications, data and devices. Manual freight processes should be in addition to automated asset and service freight tools. Combining these technologies enables teams to identify the security priorities of applications, data and devices.
These tools are used to understand where these important resources are located and who should access them. This process effectively creates a map for security architects to understand where security tools are best implemented.
2. Understand existing cyber security restrictions
Once the security surface has been mapped, the next principle of zero confidence is to evaluate whether cyber security regulations are already in place. Many in the field of information technology Existing safety tools can be useful When implementing a zero confidence strategy. However, they can be used in the wrong place or use an outdated perimeter structure model. These appraisal tutorials are useful when linked to a protected surface map because it allows IT security architects to reuse or reuse existing tools to reach the extended areas where cloud and other web-based resources now occupy.
3. Combining new tools and modern architecture
In most cases, existing cyber security tools do not meet the complete, ultimate zero-confidence framework model. Additional tools need to be added to provide extra layers Security gaps have been identified During the implementation of zero confidence. The good news is that modern tools are designed to reduce the amount of space that traditional tools have.
Examples of tools that corporate IT stores typically implement to meet the requirements of a zero confidence framework include network MicrosectationSecure access control to all applications and data Single login, And multifactor recognition. In addition, Advanced threat security tools Security policy can be used to identify emerging threats and to protect resources precisely where they are needed.
4. Use a comprehensive policy
Once all the technologies needed to build a zero confidence structure are in place, security executives work to make use of those tools. This is accomplished by developing and implementing a zero confidence policy, which can then be applied to a variety of safety devices.
Zero belief policies are rules that allow access to a variety of sources, allowing access only when absolutely necessary based on strict standards. Policies should outline exactly which users, devices, and applications should have access to which data and services. Once top-level policies are structured, administrators can be configured to adhere to security devices Permission list Of the rules of admission, when everything is denied.
5. Monitoring and alert
The last principle of zero confidence is to carry out the necessary monitoring and use of warning tools. These tools give security personnel a measure of whether implemented safety policies are in place and whether cracks in the structure have been exploited.
It is important to remember that nothing is completely safe, even if it has a zero confidence structure. Tools still need to be used to catch them when malicious acts occur so they can be sealed quickly. There must be systems as well Analyze the root cause Detect and fix any defects in the existing security appearance.
Distributed security structure such as zero confidence can be the biggest challenge to properly monitor security activity center executives. Fortunately, there are modern cyber security tracking tools that combine automation and AI capabilities to help ease that burden. Such as modern security surveillance equipment Network detection and response And Security Band, Automation and Response, Help reduce the human resources required to identify security incidents, while at the same time identifying the root causes and remedial measures.
