The development of cloud technologies and distributed work models changed the necessity of security for companies. Even though the cloud has been highly beneficial for companies, it also attracted the attention of malicious actors such as hackers and ransomware attackers.
Distributed work models, on the other hand, have significant advantages for companies. For example, thanks to these new models, enterprises can work with highly skilled professionals all around the world. However, the problem with cloud technologies applies to this practice too. Employees need to access the corporate network from distant locations, and this may lead to cybersecurity vulnerabilities.
To this end, with the developing edge computing technologies, modern companies need comprehensive cybersecurity solutions that can protect both the access and the network since a breach may cause considerable monetary and reputational damage.
As cyberattacks are getting more sophisticated every day, traditional network security solutions may not provide the security modern enterprises need. Luckily, some cybersecurity solutions can fit well in today’s business world. If you are looking for solutions that deliver comprehensive security, don’t worry, we got you covered. In this article, we will take a look at two specific cybersecurity solutions: Secure Access Service Edge — SASE and Zero Trust.
What is Secure Access Service Edge?
Secure Access Service Edge, SASE for short, is relatively a new cybersecurity framework that unifies wide area networking (WAN) and cybersecurity management services into one cloud-delivered platform. It aims to increase control over the network and reduce the complexity of managing it. SASE’s infrastructure and network security integration addresses the issues related to cloud technologies and the transition to digital enterprise models. As the workforce gets more distributed every day, traditional on-premise perimeter security models can not deliver the protection needed.
SASE, on the other hand, enables the adaptive construction of security policies, secure access, and management regulations independent of the geolocation of the organizations or the users. The SASE framework is created to enable business IT experts to register authentication and setting to define the specific degree of efficiency, dependability, protection, and expense required for each data connection. The architecture provides these capabilities by utilizing five key technologies.
SD-WAN is intended to redirect network activity to link distant endpoints from enterprise locations, whereas SASE is aimed at safeguarding network activity that departs from any place and reaches any endpoint.
Cloud Access Security Broker — CASB
One of the most essential components of SASE implementation is the Cloud Access Security Broker, which works similarly to a firewall, allowing a corporation to expand security control outside its network border. CASBs can be on-premises or in the cloud, and they operate between cloud server users and cloud service providers.
Zero Trust Network Access — ZTNA
SASE employs a Zero Trust strategy for cybersecurity, which limits user access and availability to corporate assets, reducing the risk of insider attacks. As a cloud-based service focused on strengthening network safety and availability from distant locations adopting various network security elements as long as they fit within the overall framework of the SASE. For example, when comparing Zero Trust security vs Sase, companies should keep in mind that both practices can work well together if implemented correctly.
Firewall As a Service — FWaaS
The FWaaS technology scrutinizes traffic flows to spot and mitigate vulnerabilities. This operation analyses the content within every information packet’s header, identifying where it originated from and other patterns that might signify it is malevolent. SASE utilizes FWaaS to secure the remote access of endpoints and provides companies with better visibility and control over their network.
Secure Web Gateway — SWG
An SWB analyses online traffic in real time, correlating data to corporate regulations and restricting any material that is inappropriate or breaches company policy. It also offers data leak protection, allowing businesses to prevent sensitive data from being disclosed or exploited by third parties.
What is Zero Trust Security?
Next up is our second cybersecurity solution: Zero Trust. It is a network security solution that regulates access privileges according to predetermined security policies. Utilizing the security principle of least privilege (POLP), the framework reduces the risk of access-related risks.
Since remote access is common in today’s enterprises, Zero Trust is considered a logical approach to network security. Before authenticating endpoints, the framework necessities them to be verified. The process is applied for every access request continually which reduces the impact of data breaches and prevents lateral movement. The approach’s goal is to avoid presuming that everyone who has previously accessed the network is always trusted.
By verifying individuals, endpoints, platforms, or apps on a particular instance basis, Zero Trust preserves identity management and provides regularity to key operations. By segmenting and isolating the network, services, and apps, and using ZTNA or MFA — Multi-Factor Authentication, administration and compliance requirements may employ more unified risk mitigation over identity management.
Which One to Choose for Your Company?
Zero Trust and SASE are rather an approach than ready-to-use services. To take advantage of these frameworks, a company should embrace the change to cloud-based systems and detect the vulnerabilities of their network crystal clear. As we mentioned, they are not products, so it is important to see the implementation process as a transition to cloud-based security from traditional perimeter security.
When it comes to the question “which one?”, the answer should be both of them if you are planning to implement a cloud-based cybersecurity solution. The reason is they, in essence, work together. SASE makes use of ZTNA to provide companies with secure remote access and Zero Trust fits well into SASE architecture to deliver comprehensive protection. Also, both of them deliver significant benefits to companies such as meeting regulatory compliance requirements, reducing the complexity of managing access requests and networks, and increasing efficiency.
With the increasing remote access requests, corporate networks may become vulnerable to data breaches and cyberattacks. Embracing cloud-based network security approaches can help companies to keep their networks, systems, services, and apps secure.
This way enterprises can demonstrate their reliability, prevent cyberattacks and most importantly increase their brand trust and reputation. The business world adopts cloud-based technologies and benefits from their advantages, however, vulnerabilities may be frightening from time to time. Luckily, implementing these cybersecurity solutions can provide peace of mind to enterprises.
