What is zero trust and why is it important for your business?
February 11th, 2021 by admin
The COVID-19 pandemic has caused many businesses worldwide to shift to remote work. While before the pandemic, remote work privileges were just a perk offered by some businesses, many other companies have since made it a permanent arrangement. In fact, it's estimated that by 2025, 70% of employees will be working from home at least five days a month. This means that workers will have to access company resources outside of the office using potentially unsecured devices and connections. Most organizations use a "verify, then trust" model that gives anyone with the correct login credentials access to their network. However, cybercriminals can easily steal login information and use them to hack into private networks. Implementing a zero trust policy is a good way to mitigate this threat. What is zero trust? Zero trust is a security model created by John Kindervag in 2010. Zero trust is centered on the belief that businesses should never trust anyone outside or inside its perimeter. The core principles of zero trust include: 1. Re-evaluating default access controls The zero trust security model posits that there's no such thing as a trusted source, which is why all requests to access company resources must go through a rigid process of authentication and verification. 2. Implementing multiple preventive measures To prevent data breaches and minimize their damage, the zero trust model uses the following preventive measures:- Multifactor authentication (MFA) MFA is an authentication process that requires two or more pieces of evidence, such as email/SMS confirmation, security questions, biometrics, and logic-based exercises, to confirm a user's identity. This added layer of security will strengthen a network's defenses against attackers.
- Principle of least privilege (POLP) The concept behind POLP is that it limits the access rights of users to the bare minimum permissions they need to complete their tasks. For example, employees who work in the marketing department should have access to the customer relationship management programs, but should not be given access to the payroll database.
- Assigning limited privileges prevents malicious insiders from accessing information outside their job function. And should someone steal a particular user's login information, the person who stole it still won't be able to access other programs or databases within the company's network.
- Microsegmentation This cybersecurity method divides your network into small zones to make access more difficult for hackers and thus contain breaches more effectively. If an attack occurs, the attacker will be limited to a specific zone and won't be able to move outside that microsegment.
