Let’s explain Zero trust security in simple terms. It will understand more easily and we will get an idea of why we need zero-trust security.
What Is Zero Trust Security In Simple Terms?
Zero trust security is a new strategy in which identity is fundamental to cyber security. In this strategy, we need to build a security system that relies on what the user does, not who the user is.
This means the system will protect data and the network in real-time. Regardless of where users are located.
The idea is to replace the idea of “permissions-based” security with “risk-based” security. In other words, an authenticated user can access resources based on their risk profile. Rather than their identity.
In this concept, all users are treated as potentially malicious until they’ve been explicitly proven otherwise.
How Zero Trust Security Works?
The traditional approach to identity management and access control is known as “permissions-based” security. And it’s often referred to as “identity-based” or “stored-credential-based” security.
Permissions-based security typically relies on a combination of the following:
- digital certificates, and
- one-time passcodes (OTP) to authenticate and authorize users
This model has been widely used in enterprise environments for years. But it’s no longer sufficient in the modern threat landscape. Here’s why:
Passwords are an insecure form of authentication. They’re easily guessed or stolen via phishing attacks. Or brute force attacks against password databases.
They’re also difficult to update or change when compromised (especially across multiple platforms).
Passwords don’t provide an accurate indication of the risk of compromise. They’re also relatively easy to steal and reuse across multiple accounts if exposed in a breach.
Having a single password for all accounts makes it easier for attackers. They gain elevated privileges once they’ve compromised one of those accounts.
Requiring users to change their passwords regularly isn’t very effective. Since many people reuse passwords across multiple services (remembering unique passwords for each service can be challenging).
An OTP token provides only limited protection since most OTPs can be obtained with little effort (usually for free).
OTP provides very little information about risk. Since any attacker can obtain one from multiple sources. Such as SMS messages and email).
Digital certificates are rarely revoked once issued. This means stolen or compromised private keys can be used indefinitely. By the attacker without getting caught.
If a digital certificate is revoked after being stolen or leaked, there will be no way for legitimate clients to continue.
How is Zero Trust Beneficial?
The main benefit of Zero Trust security is that it’s a proactive strategy. It focuses on protecting data and the network in real-time. Regardless of where users are located.
Zero Trust security also provides a clear indication of risk for each user or device accessing the network. This is especially useful for logging and auditing purposes.
Zero Trust security also ensures that users are:
- highly authenticated,
- authorized, and otherwise authorized to access resources.
In conclusion, Zero Trust is a relatively new approach to cyber security. We’re already seeing it in practice by major organizations around the world.
The concept of Zero Trust security isn’t difficult. However, applying this concept to your specific business can be challenging.
That’s why you should choose an experienced partner. Such as Midpoint Systems to help you implement Zero Trust security.
