First, what is Zero Trust security?
Zero trust security is a security method that requires all users and devices to be verified and permitted before they may access resources. It is a proven model for implementing robust and selective security.
What do we mean by Zero Trust Architecture?
Zero trust architecture is a cybersecurity strategy that posits that no user, device, or network, whether within or outside an organization's perimeter, should be trusted by default. In contrast, typical security methods, such as firewalls, rely on perimeter-based protection to safeguard internal resources. Zero trust architecture, on the other hand, takes a broader approach to security, assuming that every person and device must be constantly examined and approved before access to any resource is granted.
"Never trust, always verify" is the central tenet of zero trust architecture. This means that all users, devices, and network traffic must be verified and authenticated before being given access to any resources, regardless of where they are or what device they are using.
This requires the use of a number of tools and approaches, including multi-factor authentication (MFA), encryption, micro-segmentation, and the principle of least privilege access restrictions.
Zero Trust success begins with casting a broad enough net to address identity sprawl. As businesses transition to a multi-generational, hybrid, and edge IT world, this involves concentrating not just on people, but also on machine identities and ever-expanding accounts. If you draw the circle too narrow, you risk opening the door to dangerous actors.
The fact that zero trust architecture decreases an organization's attack surface is one of its main benefits. Because access to resources is restricted to those who have a need-to-know basis and persons and devices are constantly being checked and approved, zero trust architecture makes it even harder for attackers to get access to sensitive resources. Zero trust architecture also makes it easy for businesses to identify and address known vulnerabilities quickly, minimizing the impact of any potential breaches because it operates under the premise that every user and device is potentially compromised.
Creating a zero trust architecture may be a complicated and multifaceted task that involves a variety of security technologies, rules, and processes. Yet, the advantages of zero trust architecture in terms of greater security, decreased risk, and better regulatory compliance are making it a more popular approach to cybersecurity.
5 ways Zero Trust can help secure your organization today
Here are five ways zero trust security may help organizations:
- 1. Reduce attack surface
Zero trust security decreases an organization's attack surface by only allowing access to resources on a need-to-know basis. This implies that the attacker will only be able to access a subset of the network's resources, even if a user or device is compromised. For instance, a zero trust policy may limit access to sensitive information based on parameters including location, device type, and user role.
- 2. Enforce strong authentication
To achieve zero trust security, all users and devices accessing resources must employ strong authentication. Multi-factor authentication (MFA), biometric authentication, and device posture checks are examples. By demanding robust authentication, organizations may better ensure that users and devices are who they claim they are and that they conform towards certain security requirements before being given access to resources.
- 3. Implementing granular access controls
Zero trust security is providing granular access restrictions for all resources, including applications, data, and network segments. As a consequence, people and devices receive the resources they need to accomplish their duties and access is immediately granted and withdrawn. For instance, a zero trust policy might limit access to a particular application or data set to a specific subset of users who have a demonstrated need for it.
- 4. Monitoring and analyzing network activity
Continuous monitoring and analysis of network activity is required for zero trust security in order to discover and respond to possible attacks in real-time. Monitoring user behavior, identifying unusual network activity, and examining system logs are all examples of this. Organizations can notice and respond to security events more effectively by monitoring and analyzing network traffic.
- 5. Automation in Cyber security
Using automation and orchestration to speed security procedures and lower the likelihood of human mistake is a key component of zero trust security. This can involve automating security policy enforcement, detecting and responding to threats with machine learning, and organizing incident response procedures. Organizations may better expand their security programs and respond to security issues by embracing automation and orchestration.
Zero trust security can fine tune your IT resilience and protect you against multiple sources of threat. Closing the cybersecurity gap may be a painstaking job, but the loss of being hit by a malware, data leak, or identity theft can cost the organization much more than to develop a zero trust security for their systems and networks.
