Cyber-security for the Edge Cloud

Edge computing and localized data storage provide an array of advantages to end-users and organizations. Taken along with the capabilities of 5G, this tech can bring in an entire new category of applications. The traits of edge computing also facilitate a broader implementation of IoT gadgets.  

But, edge servers and edge-based gadgets and apps are especially susceptible to malevolent actors and attacks engineered by them. In their haste with regards to implementing these solutions, organizations typically forsake security aspects that need to be considered. Additionally, several devices implemented in the edge network don’t possess the standard computational prowess that enables the robust security possible in the conventional cloud network. 

This is why it’s more and more critical that edge networks are developed in such a fashion that cyber-security considerations are solved in the foundational design. It’s vital that the edge installation forecasts and thinks about all variants of attacks, while carrying out the implementation of a cyber-security solution that makes sure that no information or functionalities are compromised. 

Potential cyber-security attacks that require to be contemplated on 

While hackers continue to innovate for all the wrong reasons, there are some standardized cyber-security attacks that every organization is required to be concerned about. In this blog post, we put forth the cyber security problems that require to be solved. Further, we will talk about potential solutions. 

DDoS (Distributed denial of service) attacks 

DDoS attacks are widespread. They are simplistic in design but very efficient in effecting damage. In DDoS attacks, hackers typically compromise devices with bots, developing a botnet. When needed, these bots can be leveraged to launch limitless requests that exert excess load on the servers and disable the process of authentic requests. After infecting edge gadgets, malicious actors now have at their disposal edge servers. This could have the outcome of complete loss of services and information. 

Edge servers usually feature less computational prowess than cloud servers, making them more susceptible to these variants of attacks. Additionally, edge devices like sensors typically consist of very simplistic hardware and are not developed to keep up with such increased volumes of requests. Taking into account that DDoS attacks are very widespread and capable, and that edge networks are especially vulnerable to them, any edge network must be developed from the ground up to avert such attacks. 

Attacks via edge-native apps 

Edge servers can be compromised from gadgets via DDoS, but apps working on those gadgets can also present an issue. The application code could be developed with security deficiencies or the authenticating protocols can stop working and facilitate easy points of entrance into the network. It’s critical that communication amongst apps and servers is meticulously surveyed and secured. 

IoT applications are especially extremely susceptible. DDoS attacks can disempower entire HVAC smart systems. The consequences can be immense, particularly taking into account the volume and kinds of information that can be lost or compromised. We will now observe potential solutions to security problems that are faced in the edge cloud. 

We just discussed potential origins of cyber attacks on the edge cloud network. With the proliferation of edge and 5G technologies and the more widespread utilization of IoT gadgets in residential settings and cities, cybersecurity is more critical than ever before. We will now observe which design principles can have implementation at the core of the network to make sure that maximum levels of cybersecurity are present. 

Safeguarding the edge-cloud from the three primary origins of attack 

We highlighted that the primary origins of problems in the edge cloud can come from distributed denial of service attacks, web-based sources, and apps that are native to the network. These are representative of a major threat to information and functionalities of the network. To avert serious damages, these aspects of security need to be thought about. 

DDoS attacks and security 

DDoS attacks overload the network and prevent authentic traffic and their requests from being completed. These attacks are typically executed via bots that get setup network-connected gadgets. After a botnet has been setup, the hacker can switch it on at any moment. 

These variants of attacks are the most typical, and hence, it’s critical to implement robust security frameworks. Right from the start, smart resource pools should be setup for any consumable asset that could be compromised. It’s common sense to allot the amount of memory that is permissible for each connected gadget, in addition to the number of active network connections, UDP, and TCP ports. Another safety measure to be instated is the inclusion of watermarks and a report system that would caution the network with regards to any intrusive developments prior to the attacks being initiated.  

As a safeguard in the scenario of a successful DDoS attack, the network design should consist of a system for the allotment of reserve assets. These can be implemented so that the network can keep operating even during catastrophic assaults. Assets can be freed up in the case of emergencies, enabling the end-users to retain functionalities within the network. 

Safeguard from web-based sources 

As we specified earlier, several gadgets and applications on the edge don’t require an active web connection to operate. Totally barricading off web traffic is a safe method to avert malicious intrusion, particularly with regards to devices and sensors in warehouses or industrial IoT. 

For services that need to be online, all connections need to be documented and undergo monitoring. An even more sophisticated solution is to develop a system that enables connections that come exclusively from localized applications. These systems would barricade off any and all packets coming from the web that are not connected with permitted and established connections. 

As we move on with the production of edge-cloud networks and gadgets, we are required to make sure that our information and functionalities are safeguarded. Just like with any innovative tech, cybersecurity can be a pressing issue at the beginning. But, if we go about applying robust security principles in the fundamental design surrounding a network, we have already done a great deal to ensure adequate security.
