Why Zero Trust Security Is the Answer to Evolving Cyber Threats

In the modern digital landscape, cyber threats are more changing and complex than ever. While cloud services, remote work, and insider threats have made the “castle-and-moat” approach obsolete, the Zero Trust Security brings that new age cybersecurity framework built on the principle of “trust no one, verify everything.” 

What is Zero Trust Security? 

Zero Trust model considers every request originating from inside or outside a corporate network as a potential threat. Unlike the traditional security model, access controls and identity authentication have to be done at every step of interaction. Other than multi-factor authentication (MFA), micro-segmentation, least privilege access, and continuous monitoring technologies, Zero Trust ensures that sensitive resources are accessible only to authorized users. 

Why Zero Trust Matters 

Conventional security models are assumed to be based on threats coming from outside an organization, based on a “trusted” internal network. Thereby, firewalls and VPNs protect the perimeter on which this model relies. However, the introduction of cloud environments, mobile devices, and remote work has demarcated the perimeter as no longer a reliable barometer of trust. 

Zero Trust solves this problem by abolishing the notion of a secure perimeter. Instead of defending a network boundary, it secures the individual user, device, and applications. The principle of “never trust, always verify” applies such that no device or user is trusted automatically irrespective of location. 

Key Principles of Zero Trust

  1. Identity and Access Management (IAM): A zero-trust model is heavily reliant on strong identity verification. The account, device, or application should therefore authenticate before it accesses resources. The practice of multi-factor authentication has become common so that security goes beyond just passwords.
  2. Least-Privilege Access: The system provides the user and device with the minimum access that a particular task requires. With this, the effect of potential breaches will be very minimal since an attacker can’t just move laterally anywhere within the network. 
  3. Micro-Segmentation: Zero Trust approaches to break the network down into small, isolated segments and each such segment has access controls. Consequently, even if an attacker manages to take over one such network segment, it limits their capacity to move laterally from one system to another. 
  4. Continuous Monitoring and Validation: Unlike traditional models, which only validate a user’s access at the point of entry, Zero Trust continuously monitors activity and network traffic. Through its focus on behavioral analysis and the identification of anomalies, Zero Trust can pick up and address threats in real-time. 
Benefits of Zero Trust Security 
  1. Reduced Attack Surface: With Zero Trust, every access is tightly controlled and monitored, hence removing or minimizing chances of un-sanctioned access. Even if an attacker gets hold of one part of the network, then movement is limited. 
  2. Adaptability to Modern Work Environments: Zero Trust is developed and built to support cloud-based services, work from anywhere, and handheld devices, ensuring security in diverse environments. 
  3. Improved Compliance: Zero Trust enforces strict access controls along with continuous monitoring to ensure the regulatory requirements involving those like GDPR, HIPAA, and PCI-DSS. 
  4. Enhanced Incident Response: Zero Trust’s real-time monitoring would enable companies to quickly discover and neutralize cyber threats in real-time, reduce reaction times, and therefore cause less damage. 
The Future of Cyber Defense

Zero Trust has become the new norm in cyber security in an age where there is an increased sophisticated threat against cyberspace. This approach eliminates assumptions about trust and, consequently, verifies every user, device, and request to minimize vulnerabilities and strengthen defenses. As businesses navigate the complexities of remote work, cloud adoption, and the evolving cyber risk landscape, adopting Zero Trust is no longer optional—it’s essential. 

The Zero Trust model offers an opportunity for businesses today to future-proof their cybersecurity strategy, improve detection of threats, and be better protected against modern cyberattacks by trusting no one and verifying everything: this is the future of cyber defense.

Application Security in 2022

Image
  1.As enterprises move more of their data, code, and operations into the cloud, attacks against those assets can increase. How can application security measures reduce the impact of such attacks? The growing adoption of cloud environments has made web applications equally vulnerable as networks. For example, the Radware’s The State of Web Application and API Protection report shows that 70% of production web applications now run in cloud environments. Thus, holding these modern infrastructures with traditional security practices is like using glues and strings. IMG Source:  SiliconIndia Besides, the threat landscape is ever-evolving, with ransomware, data leaks/theft, or DDoS attacks breaking the news headline every day. Therefore, companies must take a holistic approach towards securing their sensitive data like company, employee, and client information as loss of these pieces of information can not just break the bank but also cripple the long-built reputation. Solutions l...

What is a network packet broker and why does your network need one

  In an ideal scenario, an organization would have complete visibility into its network, knowing exactly who is on the network, when and where they are, and what level of access they have. This visibility would improve network performance, enhance efficiency, and prevent security breaches. However, according to an EMA study, most enterprises monitor less than 70% of their networks. 38% pointed to network complexity as a significant challenge when asked why. This lack of visibility creates blind spots and vulnerabilities, providing opportunities for attackers to hide, exploit weaknesses, and carry out breaches undetected. While employing advanced network monitoring solutions seem like a clear choice, they come with several challenges. These tools require specific types of data to function effectively and often compete for traffic packets from SPAN ports or get overwhelmed by the sheer volume of irrelevant data. A Network Packet Broker (NPB) becomes crucial to address these issues. ...

Web Application Firewall – A security solution to protect from the ever-evolving cybercrime

 Cyber crimes are a constant threat to businesses and they are increasing by the day. As businesses grow, they become more vulnerable, reinforcing the need to protect them against rising cyber threats . Although cyber security has been one of the top concerns for enterprises for a long time. The increasing sophistication of these crimes is causing more headaches now. In addition, attacks like identity theft, credential theft, and data leaks have the potential of harming users by exposing their private information and undermining their confidence. The situation worsens with the increase of bot-based attacks and the accessibility of commercially available tools that make it simpler than ever before for hackers to commit such crimes. As a result, contemporary solutions, like managed and subscription-based services, such as Web Application Firewall (WAF) can assist both organisations and their consumers. They have the advantage of being simple to use, economical, scalable, and endowed ...
