Organizations have seen sensitive data being compromised in various ways. It can be exposed to unauthorized third parties, or altered, or breached, or even get stolen. The first nine months of 2019 recorded 5,183 breaches with 7.9 billion exposed records. Many high-profile cases made headlines, such as Zynga, a US-based mobile and online game producer, announced that a cybercriminal accessed the private details of their customers who used to play “Draw Something” and “Words with Friends” games. The breach affected 218 million users. Similarly, last year, nearly 162 million records of Dubsmash got compromised. After this, the security professionals came up with numerous solutions to fight against the increasing number of crimes. Even organizations invested fairly on the security budget to increase the efficiency and productivity of their network. But with the adoption of the Internet of Things (IoT) and various cloud services, the network has taken a distributed form. This advancement highlighted the need for enhanced network security. The rising cybercrime rate also disrupts the network edge, a point where all third-party network services, including employees, customers, and other stakeholders, meet.
Network Edge – A New Attack Zone
The “network edge” is a combination of one or more boundaries in a network that clearly defines who controls the underlying network infrastructure solutions. It offers multiple crucial functions, which are – computing, analytics, and security. These functions ensure that the business stays afloat at all the enterprise locations. For example, a firm’s network infrastructure consists of wired and wireless LAN with one or more data centers. Each segment of this network is owned and managed by the respective corporate IT department. But with the introduction of remote offices, world wide web, and cloud-based resources, the internet service provider took the responsibility of connectivity controller. The meeting point of an enterprise and third-party networks are referred to as the “network edge.”
In today’s world, ongoing network traffic is monitored by the devices installed at the unsupervised network edge. Thus, the network edge is emerging as a new “attack zone” for cybercriminals. As stats suggest, over 75 billion IoT devices will be connected to the web by 2025, creating a need for proactive solutions at the network edge. This defensive approach would focus on maintaining data privacy and the integrity of the network.
To learn more about IoT related security risks and their effective elimination, take a look at what Romeo Siquijor, an experienced IT-business leader, has to say:
The increasing cloud and IoT deployment opened new business windows. But at the same time, they created data security and management related challenges. The primary reason behind this discrepancy is that configuration routines and policy management frameworks are not progressive in nature. They are incapable of adapting cloud-based transformation over traditional on-premise infrastructures. For instance, organizations usually hand over the controls of their cloud-based networks to third parties. Unfortunately, these cloud service providers get bombarded with numerous cyberattacks, including distributed denial-of-service (DDoS). Last year, in 2019, Imperva found over 500 million packets per second (Mpps), one of the massive packets-per-second DDoS attacks.
Note: Packets per second is the standard unit used to measure the intensity of a cyberattack.
Network Edge and Edge Computing
The concept of network edge and edge computing might sound similar, yet, they differ from each other. Edge computing deals with modern-day data centers and cloud-based infrastructures to improve their efficiencies. The physical distance between users, applications, services, and data creates a condition of low throughput and inefficiencies. Edge computing brings the data closer to its applications. To achieve this, the traditional design of data centers has been decentralized. Now, organizations put up data center nearer to the end-users, thus, reducing the gap between data/applications and end-users.
The decentralization of data under edge computing brings in another set of security challenges. These include frequent DDoS attacks, zero-day vulnerabilities, and several others. But by making smart and strategic investments can help to overcome the security risks associated with the network edge.
To combat these modern-age security issues, organizations need a skilled network security engineer. Certified Network Defender (C|ND) ensures that the professional possesses all the significant skills and knowledge. The program concentrates on offering hands-on experience to all its attendees, helping them to learn how to protect, detect, and respond to cyber threats and attacks. The globally acclaimed C|ND is mapped to the responsibilities of the Department of Defense (DoD) based system/network administrators. It also covers global job roles and responsibilities.
