The year 2020 has been the year where remote access and remote functioning were at their peak. With everyone locked in their premises, the only way to keep moving was through remote and virtual systems. The exposure to remote and virtual functioning also led to huge opportunities for attackers and hackers to form new ways to breach the systems.
Common cyberattacks like ransomware, malware, denial of service, and phishing were seen at blistering heights. It was found in the Fintech news report for 2020 that ransomware payments rose to a record high of $111,605, a 33% increase from the numbers as compared to 2019.
This is just the warning signal for 2021, as hackers and attackers will be more equipped and ready to get all in. Being the reason why we have to employ some of the robust security solutions like the Software Defined Perimeter and Zero trust security.
Why Zero Trust Software Defined Perimeter for 2021?
With security mechanisms leaving loopholes to be targeted by trusting unusual behaviours and access, a zero trust network access will make sure that no user asking for access is trusted blindly, whether it is a normal user or a corporate executive. A zero trust software-defined perimeter is a VPN replacement to a better and more secured remote workforce security. Zero-trust security will make sure that no one is trusted if any unauthorized local area network access or other unscrupulous access is processed.
A zero-trust network also includes a combination of microsegmentation that comes along with an identity-based access security mechanism. With the amalgamation of Microsegmentation, the monitoring and control over any particular network became robust with improved isolation. Whereas, the identity-based security mechanism ensures that the users are verified multiple times upon login, and their activities are thoroughly checked and detected.
- Eradicates the location-based way of designing networks
The traditional designs of networks have not been more identity-based but have been more of physical location-based security. Those orthodox network designs were built more on branches and datacenters and not around users and the resources they need to access. A zero trust SDP pitches in a new way of designing networks that is more of a location-based network design.
- A secure network perimeter
The zero trust SDP brings in the most compact, rigid, and secured network perimeters that can shield all the devices connecting from different locations. It comes with clear demarcation points for all the corporate and personal devices accessing resources and connecting from different locations. The increase in the migration of systems to Software as a Services (SAAS) and Infrastructure as a Service (IAAS)can be facilitated with a hardcore security perimeter of zero trust network access.
- A solution to VPN security issues
Users of today get broad access when they log into their VPNs. Well, the hard fact is, a majority of network resources are still visible to the attackers through VPNs. Even if your VPN network is well-calibrated with effective segmentation, it still has higher risks of getting exposed to malicious attackers.
With VPNs, users might also have to face complex configurations with unreliable client applications. An application’s performance also degrades with huge latencies when backhauling traffic to centralized data centres for security purposes or maybe VPN termination. A zero trust SDP along with microsegmentation acts as a perfect VPN replacement that will completely help you escape from these difficulties by offering a streamlined process of security processing where there are no to minimal latencies.
- Prevents the misuse of VLANs
The genuine use of VLANs has always been to improve and enhance performance by dividing broadcast domains. Though with time, their role is being tried to channel more towards providing security for which they were never really apt. VLANs are not considered to be probable to span across multiple locations. It can get very difficult for the clouds where VLANs cannot be supported in their native forms.
Identity-based microsegmentation is the way
The major point of having an identity-based microsegmentation is granting access to users in a permanent manner that does not depend on the point of connection. This promotes effective monitoring and control on the part of the IT team and administrators as it helps them to understand and get hold of what is happening in the network and without engaging in those time-consuming investigations. It also helps to consistently lay down access policy rules in the important places of the network.
An identity-based microsegmentation will act and implement decisions based on the information already stored such as locations, device type, and ownership. This solution will also ensure and check whether the traffic carries a specifically authorized identity.
Zero trust Software Defined Perimeter expectations in 2021
The challenges faced by systems and networks in 2020 and still facing are mainly to consolidate and coordinate network and its security delivery for the remote users. Taking a major shift and transition from VPN to a lower-risk variant will be a must!
Uniform solutions like zero trust SDP will help in granting access to data, resources, and applications that are not based on any location bias. A more centralized system of managing access and setting important policies would be required.
Also, a globally distributed abstraction layer that can form an additional layer on top of the existing infrastructure can be essential for providing secured and seamless access from anywhere by anyone and for site-to-site connectivity. The zero trust SDP along with microsegmentation should be built-in for every system and network going forward in 2021.
With increased threats, increased investments for taking strong cybersecurity measures are also on the lookout by almost all kinds of businesses that are functioning remotely. As per the forecast analysis by Gartner, the global information security market is expected to go up to $170.4 billion.
Going forward, remote workers are absolutely going to be the major targets for cybercriminals. This might also lead to significant cloud breaches and hacks. Also, with 5G coming anytime soon, the bandwidth of remotely connected devices will increase ultimately leading to higher cyber-attack risk.
Being the reason, it is quite important to be security ready for your network by employing the best of zero trust security and microsegmentation. Instasafe could be your one-stop platform for securing all your important security integrations and solutions. Solutions that are robust and compliant to fight all the major security threats arising in your system.
