The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower. The hardware and communication interfaces are owned by a specific vendor, and its software-driven functionality is tightly coupled within the hardware.
Traditionally, this has worked well for mobile network operators (MNOs). However, there are several drawbacks to consider – for instance, upgrading or changing the wireless network demands physical hardware replacements throughout the network, which is cost-inefficient, labor-intensive, and time-consuming. Furthermore, the equipment and interfaces that connect the hardware are owned by the vendors that originally supplied them, which locks MNOs into existing relationships with them.

I’m a new-ish remote worker and, although I love 99% of everything associated with it, lately, after every virtual meeting I have, I’m feeling exhausted and drained. And not in the normal, everyday work exhausted and drained kind of way. It’s a peculiar combination of eye strain, headaches, and general malaise that I really only experience after a long day of virtual meetings. I was curious if others were feeling the same so I did a completely non-scientific study of my remote work friends to see how they’ve been feeling. Turns out, I’m not alone.
Workers everywhere are going through a huge transition as the work from anywhere model has accelerated at breakneck speed since the pandemic. Although some parts of the world are slowly returning to a new normal, many employers, including Tangoe, have made the decision to keep the work from anywhere model while some organizations are electing to use a hybrid model of partly remote, partly in-office.

5G is a little higher at 3.4GHz to 3.6GHz, but that's tiny when you consider that microwaves go up to 300GHz. And visible light comes in at a range of around 430THz to 770THz. That's more than a thousand times higher than the maximum microwave – and 100,000 higher than 5G. Dangerous radiation, like UV rays, X-rays and gamma rays are also far higher up the spectrum still. Early theories suggested 5G could lead to cancer – and now crackpots have linked it to coronavirus too. But it's simply impossible for 5G to cause any of these problems. Radiation damages cells by breaking them apart, but 5G microwaves simply lack the power to do this. 5G is a low-frequency radiation, far below infrared and visible light.
In fact, it's essential that 5G is low-frequency, because higher frequencies are less useful at delivering mobile signals over large areas. We know that this level of radiation is safe, because otherwise the visible light from our televisions would have killed us a long time ago.

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.
