Paving the Path to Secure Data Access with Shield-SDA

Recent researches show that six out of ten organizations around the globe have suffered at least one Cyber-attack incident on their networks, applications, websites, critical infrastructures, mobile, etc.

The common practice in organizations is to deploy defense layers acting as “walls” and “gates” protecting from intrusions to their internal networks. These defense layers include DMZ (demilitarized zone, also known as “perimeter”) network segments and layers of firewalls.

However, the rise in number of cyber-attacks and data breached, shows us that the current network security paradigm is flawed.

DMZ network segments are deployed not only as defense layers but also in order to provide customers, partners and suppliers with controlled access to corporate data. As more and more sensitive data from the internal network is duplicated in the DMZ, this perimeter network designed to be a buffer zone has become a prime target for hackers, providing IT departments with the following challenges:

Risk of Sensitive Data Breach the DMZ is now a hub of external facing services containing large amounts of sensitive data and personally identifiable information resulting in greater risk of data breaches.

Preventing Hacking into the Internal Network from the DMZ most front-end servers located in the DMZ communicate with servers within the LAN through an incoming port in the firewall, which hackers can utilize to launch attacks into the internal network In addition such servers are accessible from the Internet and can be compromised by hackers, providing a second means of attacking the internal network.

Increased Capital Costs the DMZ network configuration also imposes a costly burden on the enterprise’s capital expenses requiring additional hardware and software licenses as a result of duplicating sensitive data in the DMZ.

Higher Operational Costs This additional hosting and synchronization of duplicated data between the LAN and DMZ requires a complex layer of data and network operations which can be complicated.

As discussed above, the network security paradigm is flawed not only within the DMZ network segments. Firewalls themselves which were traditionally thought of as impenetrable “gateways into the organization”, are now known to be vulnerable to attacks such as Shellshock and others.

It is clear then, that a paradigm change is needed in order to overcome the challenges of today’s network security practices and effectively combat cyber-attacks.

Shield-SDA (Software Defined Access) – Disruptive Secure Data Access

Shield-SDA is a disruptive and breakthrough secure reverse-access solution that is designed to overcome the challenges of today’s DMZ networks and network segmentation, prevent criminal application access, application hacking, and protect classified networks within the enterprise  infrastructure.

With Shield-SDA organizations start their journey to complete elimination of the DMZ, close incoming ports in the firewall, and eliminate sensitive data and application servers from the DMZ while gaining immediate costs savings.

Shield-SDA is a dual node patented technology, which removes the need to open any ports within a firewall, while allowing secured network access between networks (through the firewall).

Secure Front-End solution is a two tier deployment:

External Shield-SDA Node installed in the DMZ / external / non-secured segment

Internal Shield-SDA Node installed in the internal / secured segment

The role of the external Shield-SDA node is to act as a front-end to all services published within the DMZ. It operates without the need to open any ports within the external firewall and ensures that only legitimate session data can pass through into the LAN.

The role of the internal Shield-SDA node it to pull the session data into the LAN from the external RSAccess node, scan it using various application level security techniques, and then pass it to the destination application server.

Eliminating the DMZ and Cyber Security Threats

By deploying Safe-T’s patented Shield-SDA in the network, IT and application teams can fight off Hackers before they reach the perimeter, eliminating sensitive data and application servers from the DMZ, protecting their firewalls from attacks, all in a simple and cost-effective deployment. Gaining the following benefits in the process –

Simplify network and DMZ architecture Protect firewalls and networks from attacks

Eliminate sensitive data from DMZ, preventing compromising of sensitive data

Improve data security by closing firewall ports that are constantly exploited by external hackers

Gain immediate costs savings by eliminating duplicated application licenses and hardware costs

Achieve increased operational efficiency by reducing constant data synchronization

Shorten the timeframe for regulation compliance

Robust Deployment Scenarios

Shield-SDA’s robust technology provides benefits in various deployment scenarios:

Secure Access Gateway

Shield-SDA improves the foundation of the Zero Trust Network design, by allowing secure reverse-access to Zero Trust Network MCAP segments, making it an even more secure and revolutionary design.

Secure Application Front-end

Allows secure reverse-access to any application without opening any ports in the firewall, by deploying Shield-SDA as part of the application by an organization or software vendor (in the form of an OEM) in the DMZ.

Cloud DMZ

Secure reverse-access to entire organizations’ data centers with a one-of-a-kind cloud security service. This solution enables complete masking of the organization’s true location and architecture from external  users  and  attackers.

Application Access Proxy

Revolutionizes the way organizations grant secure external access to services and applications, to registered and non-registered business partners.
