From the late 1980s to the early 1990s, Network security was easy. Once an entity (a person, machine, or a process) was located within the perimeter of your network and was authenticated by your security provider (typically the engine the system you had in use), it was presumed that entity was, therefore, secure. This security structure is known as perimeter security. It worked because there weren’t any external connections to the network, and the actual network was not complex.
The simple security system wasn’t going to last forever. During the 1990s, these networks were able to connect via the web, which paved the way for the internet and email to become commonplace. And at the time of 2000s, many service providers started offering Software-as-a-Service (SaaS), which has become a strategic ingredient of enterprise business operations in this era. Today, the perimeter of the network isn’t so clearly defined. As a result, the security of networks was made more complicated.
To summarize the security situation of networks until around the year 2010:
- The network was no longer an unbroken, single border. It was becoming “porous” to support mobile remote and remote workers and business partners and introduce new third-party services.
- “One and done” authentication of the entities that requested access was insufficient for the modern and more complex security requirements.
- It’s not secure to presume that everyone on your network, even your employees, is reliable or trustworthy.
A Better Network Security Architecture
The challenges of 21st-century enterprise networking required a completely new model. In 2010, an analyst at forest research, John Kindervag, wrote an article that spread the concept for the Zero Trust architecture. Over the following years, as enterprise computing grew to include cloud computing, the issues regarding security around perimeters were becoming more urgent, and the idea for Zero Trust architecture gained traction.
Why do you need zero-trust security architecture? The basic concept behind Zero Trust architecture is simple: Zero Trust architecture is simple Always check.
To clear the fact, The Zero Trust security architecture are built around not relying on any person or thing on your network; this means that access to your network can’t give without understanding precisely the identity of who you are. Additionally, every attempt at access by any entity needs to be check at several points across the network to ensure there is no illegal entity moving vertically within the network without being identified.
The process of making a Zero Trust network work requires a thorough traffic inspection as well as analysis. By watching encrypt traffic to identify suspicious communications on networks. They malware payloads, as well in attempts to steal protect data such as credit cards, social security numbers. The SSL analysis allows for to use of the Zero Trust model to comprehensively perform what it’s supposed to protect networks from internal as well as external threats.
5 Reasons Why You Need Zero Trust Security Architecture for your company:
If you’re still not on the road to redesigning your network to turn it into a Zero Trust network, here are five compelling reasons to take the necessary steps:
- The complexity of the network – the number of users, the locations they work, the equipment they use, the variety of tasks, your usage of SaaS, the adoption of a hybrid cloud and on will grow. The Zero Trust network reduces the burden of securing your assets and helps you to pinpoint issues.
- Since it is increasing, your security boundaries could, and perhaps is already, appear as Swiss cheese.Therefore, the network’s attack surface has gotten more extensive, and the only method to decrease your risk is to establish micro-perimeters and micro-segments to gain control.
- Third-party solutions like SaaS and PaaS aren’t reliable. One security breach by a single third-party service is a lot of trusts to expose your network’s assets. The creation of robust micro-perimeters around these services is a necessity.
- Internet is fundamentally an unsecured network. Cyberattacks by criminals, amateurs, and state actors hostile to the internet are increasing. Additionally, the cost of preventing a breach or ransomware attack has grown dramatically. The financial risk has become massive and will soon be the primary factor in IT budgeting.
- Threats from insiders have increased dramatically.The management of various employees who work at office locations at home and from branch offices and ensuring access to suppliers and other business partners requires robust and well-organized security controls.
Are you making progress if you’ve begun the road to a Zero Trust network? Are you able to move faster? Does the C-suite know the issues, and is it willing to invest in a plan which could be the only thing that’s need to make the difference between success in business and irreparable failure?
If you’re not yet planning and implementing a Zero Trust architecture, why haven’t you?
