What's cyber security?

Computer security, cybersecurity or information technology security (IT security) is the security of computer systems in the theft of or damage to their own hardware, applications, or digital information, in addition to in the disruption or misdirection of their solutions they supply. The area is becoming more important because of greater reliance on computer technologies, the web and wireless system standards like Bluetooth and Wi-Fi, and as a result of development of "smart" devices, such as televisions, smartphones, and the numerous devices which constitute the"Internet of things". Due to its complexity, both regarding science and politics, cybersecurity can also be one of the significant challenges in the modern world.

What's cyber security?

Organizations face many threats to their data systems and information. Knowing all of the fundamental elements to cyber safety is the first step to fulfilling these threats.

Types of cyber security.

The reach of cyber protection is broad. The core regions are explained below, and some other fantastic cyber security plan must take all of them into consideration.

Critical infrastructure includes the cyber-physical systems which society is based on, for example, electricity grid, water purification, traffic lighting and hospitals. Plugging a power plant to the world wide web, as an instance, makes it vulnerable to cyber attacks. The solution for associations accountable for critical infrastructure would be to carry out due diligence to safeguard recognize the vulnerabilities and protect from them. Everyone else must evaluate the way an attack on critical infrastructure that they rely on could impact them and develop a contingency plan.

Network security guards against malicious intrusion in addition to malicious insiders. Ensuring network security frequently requires trade-offs. By way of instance, access controls like additional logins may be required, but slow down productivity. Tools used to track network safety create a great deal of information -- so much that legitimate alarms are often overlooked. To help better handle network security monitoring, safety teams are using machine learning how to flag abnormal traffic and alert to risks in real time.

Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices, and should be augmented by fuzzing and penetration testing. Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

IT admins know the importance of wireless network bandwidth when it comes to maintaining network performance. After all, if you have too many high-energy devices and applications putting a strain on your Wi-Fi or WLAN bandwidth, both your network performance and your end-user experience will suffer. How do you identify those bandwidth hogs, and how do you check if your bandwidth is high in general?

Fortunately, there’s an easy answer. By testing and continuously monitoring your wireless network bandwidth, you can identify and address the reasons for low bandwidth before they can seriously impact overall performance. In this piece, I’ll explain how to monitor bandwidth and how to perform a Wi-Fi bandwidth test—and why both those practices are important.

I’ll also highlight a couple of network monitoring and optimization solutions designed to help you monitor your Wi-Fi bandwidth more easily and cheaply, including my personal favorite tools, the SolarWinds® network bandwidth analyzer pack, and SolarWinds NetFlow Traffic Analyzer.

What Is Wi-Fi Bandwidth?

Before you can get started with a Wi-Fi or WLAN bandwidth monitor, you first need to understand what exactly bandwidth is, because all too often people equate bandwidth with speed, latency, or throughput — all of which are important, but different, elements of your network.

“Bandwidth” describes the highest possible rate of data transmission your network can achieve during a specific period of time. If you have high Wi-Fi bandwidth, you can receive and transmit a larger amount of data than if you have low bandwidth. High bandwidth doesn’t directly translate to faster network speeds, but it’s one of several important factors—including jitter, packet loss, and latency—that all contribute to both speed and performance. If you don’t want your performance to suffer, you need to be able to thoroughly monitor your Wi-Fi bandwidth.

How to Perform a Wi-Fi Bandwidth Test

When it comes to performing a Wi-Fi bandwidth test, the best approach is to use a tool. The internet is full of tools designed to send sample data packets across your network to test your bandwidth. However, if you want to make sure you stay secure, it’s best to use a Wi-Fi bandwidth monitor to perform the tests for you without opening your network up to yet more third-parties. An automated Wi-Fi or WLAN bandwidth monitor can give you a centralized, real-time view of your bandwidth usage alongside other device performance details.

If you want to try to check your bandwidth levels without using any tools, you’ll need to manually examine the bandwidth usage levels for every individual device on your network. This can help you determine which devices and applications are using up the most bandwidth, but the process is arduous at best and functionally ineffective at worst since your bandwidth and performance may be suffering for a long time before you hit upon the device with the answers you’re looking for.

What Is Wi-Fi Bandwidth Monitoring?

Wi-Fi bandwidth monitoring involves measuring how much bandwidth is available on a Wi-Fi or WLAN network at any given time. It involves continuously tracking bandwidth usage across devices and applications to identify high bandwidth users and to determine whether they’re using bandwidth appropriately. It also helps you identify bandwidth bottlenecks that can lead to poor performance.

Wi-Fi bandwidth monitoring is best achieved with a tool that can give you informative, real-time updates on your bandwidth utilization and network traffic. You can see if insufficient bandwidth or overutilization of your existing bandwidth is causing slow network traffic. More importantly, a Wi-Fi bandwidth monitor can help you measure the amount of bandwidth available to you at a given time (which may be different from the amount of free bandwidth).

Why Is Wi-Fi Bandwidth Monitoring Important?

Wi-Fi bandwidth monitoring is important for anyone who wants to prevent network slowdowns and proactively optimize network performance. Using a Wi-Fi bandwidth monitor is important because it can help you:

Improve Network Performance

Solving bandwidth issues can be simple, but first you need to know where to look to begin your troubleshooting. Wi-Fi bandwidth monitoring helps you find bottlenecks, identify the applications and interfaces using the most bandwidth, monitor and analyze traffic patterns, and much more, letting you drill into further details as needed. This level of insight makes it easier for you to proactively address potential issues before they begin impacting end users and causing an overall decrease in network performance.

Understand Bandwidth Use and Save Money

A lot of factors can impact your organization’s bandwidth needs. While you may need to upgrade your bandwidth, in many cases where your bandwidth doesn’t seem to be sufficient, the problem is solved by identifying your network’s “top talkers,” who are using up more than their fair share. In other cases, you may need to upgrade your bandwidth. A bandwidth monitor can help you determine the root cause of your bandwidth issues—and offer actionable advice to address it—before you start throwing money at a problem more effectively solved through other means.

Additionally, by continuously monitoring your bandwidth, you’re in a better position to identify trends that can help you plan for your future bandwidth needs, including potential upgrades you may need. After all, you never want to find yourself planning for an upgrade in response to a crisis that already occurred.

Strengthen Security

Bad actors are constantly trying to get into company systems and prey on sensitive data. By continuously monitoring bandwidth usage, you’re in a position to identify potentially malicious traffic flows and protect your data from hackers.
