An industrial secrets thief wants to infiltrate a highly confidential facility which is guarded at the entry by the best and the most skilled security personnel. The burglar successfully evades the entry security, by which he gains access to some of the most confidential information.
But what if?
What if there are security staff at every stage and level of access at the premises who perform thorough inspection of every minute detail? The chances of theft would go down,
What Exactly Is ZTSM?
Zero trust security model insists on not trusting anyone or any device that is trying to access the resources in a network, irrespective of the device’s location being inside the network or outside.
In the current scenario of the networks in an organization, the security is mostly dependent on the perimeter security devices, which are good in what they do, that is filtering and inspection of devices trying to access the network. But, what about the devices that are already in the network and are trusted?
In such situations, zero trust comes into play, by creating micro-perimeters and requiring strict identity checks and regulating access controls every time there is a need to access some resource, thereby patching the vulnerability called trust on a user or a device
Achieving Zero Trust
Zero trust can be achieved by deploying adequate mechanisms and taking strict care of processes. A few are mentioned below:
- Micro-Segmentation: Micro-segmentation is logically dividing an architecture into segments and deploying mechanisms around these segments, which makes the security more agile and efficient.
- Multi-Factor Authentication: Password based authentications have time and again proved to be inefficient, considering a phishing attack or having weak passwords which can be brute-forced and not to forget about the bypass mechanisms. Hence deployment of MFA is suggested where the authentication is secured by the user verifying the identity over just providing a password.
- Least Privileges To a User: Providing more privileges to a user than what is required can lead to an incident. Hence it is strictly suggested that a user must be provided with only adequate privileges.
- Next Gen Firewall Over Traditional Firewall: It is better to move on to next gen firewalls over the traditional firewalls considering the added functionalities including deep packet inspection, intrusion prevention system and an ability to use threat intelligence to start with.
- Enabling Strict Monitoring: All the network and internet facing assets must be monitored without fail for any slight amount of anomalous activities and raise quick alerts in order to respond to prevent any damage.
There are many other mechanisms that help in deploying a zero trust security model which can be explored further. The cyber world is becoming insecure considering the outdated security mechanisms still followed by many organizations and a lack of awareness in terms of information security. The pandemic showing a steep rise in the number of breaches is an example of why the mechanisms are outdated and that the zero trust architecture will be the order of the day!
