The promise of Open vRAN is to give back to mobile operators some form of control over their networks. The “open” refers to the opening of RAN interfaces. It is critical because it gives operators the possibility to buy the radio unit and the baseband unit from different vendors, rather than having to buy an integrated system, and therefore helps them diversify their suppliers and reduce their dependence on traditional vendors. The “v” refers to virtual. Virtualization is about disaggregating hardware and software and enabling the use of commercial off-the-shelf servers, instead of the usual purpose-built hardware, to run network functions in order to increase flexibility and reduce costs.
Across Asia-Pacific, the announcements and activities from operators including Airtel, Axiata, NTT Docomo, Rakuten Mobile, Smartfren and Telkomsel indicate a growing appetite for open and virtualized radio access networks. In countries like India, Indonesia, Malaysia and Thailand, open RAN can for example help to address the challenges of remote connectivity and to deploy a network in places where it has been traditionally difficult to achieve a satisfactory return on investment.

Network as a Service (NaaS) is gaining ground due to shrinking network boundaries and fast technological evolution in response to changing market demands. NaaS brings with it networks, operations, and business architecture that are more agile and based on open standards.
Rather than the conventional upfront cost, Network as a Service technology delivers networking gear, software, and operational and maintenance services as an operational expenditure. NaaS, like other cloud services, is maintained by the service provider and offered for a set cost.
Why Do Businesses Today, Need Network as a Service (NaaS)?
Businesses have recognized the advantages of the cloud in moving away from conventional on-premises networks. The corporate network boundary has practically vanished, and NaaS is becoming a popular technology.
Offers Flexibility to Businesses
Businesses can obtain a better return and save money by employing utility models instead of large expenditures on hardware and network equipment.
Time for Innovations
NaaS provides innovations by staying up to date with updated software versions via license upgrades and can fulfill corporate demands to introduce new goods and services more quickly.
Minimizes Operational Risk
NaaS will reduce operational risk associated with artificial intelligence (AI) and/or machine learning (ML); businesses will be able to implement the most recent product features and services.
Top 3 Benefits of Network as a Service (NaaS)
Access from Anywhere
Depending on how a cloud-based network is setup, users should be able to access it from anywhere and on any device without employing a VPN, though this creates the need for strict access control.
A user should ideally just need a connection to the internet and login details.
Bundled with Security
NaaS enables a single supplier to provide both networking and security services such as firewalls. As an outcome, the network and network security are more deeply integrated.
Cost-effective
Purchasing cloud services rather than developing one's own services generally leads to cost savings: cloud users do not have to purchase and maintain equipment, and the vendor already has the servers necessary to provide the service.

Cybercrimes have increasingly become a matter of concern for companies worldwide. Over the past few years, the rise of big-ticket ransomware attacks and exposure of perilous software supply chain infections has awakened organizations to various digital dangers.
So, the big question is, how to combat the security threats that are on meteoric growth?
The best solution is to adopt a security vulnerability assessment.
What is Security Vulnerability Assessment?
A vulnerability assessment involves a systematic review of security hazards, which helps identify IT infrastructure’s weaknesses, risks, and vulnerabilities.
When it comes to mitigating vulnerabilities and resolving issues, the collective imperative is to analyze the problem areas before getting them fixed.
A security assessment is critically important to combat the complexities and with an effective vulnerability assessment program, organizations use the tools required to comprehend the probable security weaknesses and enable the protection of systems and data from intruders and unauthorized breaches.
For most organizations, ensuring the safety of devices, networks, applications, and digital assets are part of a broader vulnerability management strategy. It includes an extensive assessment, in-depth processes, and mitigation methods to explore the entire threat spectrum.
Typically, it is conducted regularly. Vulnerability assessment offers a firm assurance in the security of data, especially when some alterations have been implemented or a new service has been added, or, for that matter, and installation of new equipment has taken place.
Each assessment provides a perspective about the risk in its periphery and suggests solutions to control the risk factors and the evolving threats.
Why Security Vulnerability Assessment Is Necessary?
The perpetual threat of cybercrime has necessitated the demand for vulnerability assessments significantly. They make organizations realize their security defects and contribute towards mitigating them.
Hackers are forever ready to make phishing attacks. As per reports, hackers are at work every 39 seconds. Thus, it is extremely important to be vigilant or complacent to activate hackers’ and cybercriminals’ machinations. Over the period, cybercrimes are fluctuating and thus need ongoing attention.
The ideal solution is to undertake consistent vulnerability assessments to safeguard confidential data, systems, and networks. Furthermore, it helps organizations understand the risk and enables smart decision-making.
To ensure security, companies ought to conduct both external and internal scans of their networks.
According to Gartner (paywall), “Large organizations with thousands of employees, tens of thousands of servers and many operating systems receive hundreds of requests per year to patch thousands of vulnerabilities that cannot be remediated in less than 15 days.”
One of the best reasons security vulnerability assessments are important is because it confirms an enterprise’s management processes and whether it has covered every critical patch through outlined existing remediation.
Why Do Companies Need Vulnerability Assessment?
A vulnerability assessment provides companies insightful details on all types of security discrepancies in their environment.
It paves ways to evaluate the risks associated with the flaws.
This helps organizations have a better knowledge of their security scare, overall weaknesses, and assets.
Moreover, the first thing that strikes us on hearing about a cyber-attack is the security of data. With the right and adequate implementation of security assessments, the safety and security of important data could be easily protected. A security assessment would be helpful to reduce irrelevant expenses and make space and increase the IT budget to invest in other key aspects.
Undoubtedly, data breach causes substantial loss to an organization, which leads to legal hassles and financial hazards. In fact, most of the time companies fail to recover the loss.
Thus, it doesn’t harm to place solid policies and methods to strengthen the entire security position of the organization and this can only be possible with a strategic security vulnerability assessment.
In a nutshell, this would keep the companies aware and, in all likelihood, keep the cyber-criminals at bay.
A CASE STUDY ANALYSIS
To cite an example, let’s take how Zensar conducted a three-pronged vulnerability assessment with port scan and penetration scanning. It determined the security of its offerings to meet customer requests for Brainshark, a leading provider of on-demand presentation solutions, helping customers deliver business interaction across 600+ ranking companies in the market.
While Brainshark knew their systems were secure and could also establish it through their documentation, they still undertook a third-party security vulnerability assessment.
Zensar’s vulnerability assessment procedures were based on the industry’s best practices that included tests for SQL injection, cookie manipulation, access control weakness, session state, and cross-site scripting.
The focus of the test was to identify the host and application security concerns. Upon completing the tests and assessments, Brainshark expressed satisfaction and was confident enough in their ability and solution. They knew their security posture was highly protected and secure.
Types of Vulnerability Assessments:
Vulnerability assessments unearth a variety of system and network vulnerabilities. This indicates the reliability of the assessment process, which is implemented with different tools, scanners, and methods that helps discover the vulnerabilities, risks, and threats.
Network-based assessment scanning: It is used to determine the presumptive network security attacks. This kind of scanning can also detect the vulnerable systems on wired as well as wireless networks.
Host-based scans: It is easy to locate the vulnerabilities in servers or other network hosts with host-based scanning. This type of scanning provides visibility into the configuration settings and legacy systems.
Database scans: Database scans ascertain the weak points in a database to preclude malefic attacks.
Application Scans: It examines websites to identify and recognize software vulnerabilities and inaccurate configurations in network or web applications.
Summing Up
Organizations need to be watchful every minute and ensure the security posture is rigorous, which is only possible with security vulnerability assessments. Based on this criterion, understanding company risks gets simplified in turn preventing intrusions and threats.
