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.

The business's move to the cloud generates new safety challenges. By way of instance, 2017 has seen nearly weekly information breaches from badly configured cloud cases. Cloud suppliers are creating new safety tools to help business users secure their information, however, the bottom line remains: Moving into the cloud isn't a panacea for performing due diligence in regards to cyber security.

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.

IoT describes a huge array of crucial and non-critical cyber physiological systems, such as appliances, sensors, printers and safety cameras. IoT devices often ship in an insecure condition and give little to no security, posing risks to not just their customers, but also to other people online, since these devices frequently find themselves part of a botnet. This presents special security challenges for the home users and society.

Server monitoring starts with collecting data (such as error rates or CPU usage), and analyzing this data can help you determine the health and performance of your IT services. Your DevOps team can analyze these metrics to shift from reactive to proactive monitoring. Instead of waiting for a problem to occur, you can create alerts to warn you when an anomaly is detected, helping you prevent problems before they occur.

Overall, the main goal of server monitoring is to reduce the number of server outages or failures. But another goal is to reduce the time needed to resolve problems. No organization manages to prevent every possible issue, but server monitoring provides the data needed to quickly identify and fix the root cause of most problems.

Server monitoring becomes more complex when the complexity of the IT infrastructure increases. A more dispersed or denser IT infrastructure is much harder to monitor. A good example of this distributed architecture is the microservices movement. Most services perform just a single task, and each of these services require monitoring to determine their performance and health.

Because of the microservices movement, there’s an even bigger need to retrieve insights from your services through active monitoring and data analysis. This article discusses the importance of server monitoring and the most important metrics to keep your IT services healthy. Additionally, it’s important to understand you can measure both server- and application-related metrics.

Importance of Server Monitoring

As the number of IT services your organization provides grows, you need better and better monitoring capabilities, so using automated solutions designed to capture and analyze metrics is almost unavoidable. Automated monitoring tools such as SolarWinds® AppOptics™ help save your team members time and resources because they don’t have to focus as much attention on resolving detectable or avoidable server issues.

Automated server monitoring helps you shift from reactive to proactive monitoring. A traditional software team only acts when a server issue pops up. However, this is a bad practice—when issues occur, customers can’t use your IT service and your organization can miss out on sales. Automated server monitoring lets you shift to proactive monitoring, so you can detect problems before they occur. In other words, you aim to resolve problems before they become bigger problems and cause a server failure.

Nowadays, customer experience matters a lot. According to Hotjar’s research on customer experience, the number one customer frustration when using digital products is long wait times. This includes the unavailability of a service, with over 20% of respondents naming this as their top frustration. For this reason, proactive monitoring is essential to improving customer experience.

Monitoring not only establishes important statistics about your application, network, and server but allows software teams to resolve problems much faster. By monitoring metrics such as disk utilization, CPU usage, and memory allocation, it becomes much easier to identify the root cause of a problem. Imagine a service experiences a failure. By looking at the memory allocation, you notice a pattern indicating a data leak has occurred. The faster you can identify the root cause of a problem, the faster you can fix it.

Top Server Monitoring Metrics to Consider

Requests per Second

The number of requests your server handles per second (also referred to as throughput) gives you a good overview of its usage. If your server doesn’t scale properly, a spike or high load can cause it to crash. Therefore, requests per second is a good metric to measure to identify potential scaling issues, especially when your organization and service usage is growing.

When you measure the number of requests per second, you should also measure the average response time for a request.

Average Response Time

Measuring the average response time tells you how long it takes for your server to handle a request and send a reply. Ideally, you want to keep your average response time as low as possible. A study by Nielsen Norman Group suggests keeping the average response time below one second to avoid interrupting the user’s flow of thought.

However, don’t stare blindly at the average response time. If you measure only the average response time, you might not notice issues like performance bottlenecks. Make sure to also measure the outer edges; most importantly, measure the slowest responses. Some developers like to refer to this metric as the peak response time (PRT). If you often see high response times for certain requests, it’s a clear indication of performance bottlenecks or other anomalies for particular requests.

Hardware Utilization

I’ve grouped metrics such as CPU usage, memory allocation, disk space, and disk utilization under the category of hardware utilization. These metrics contribute heavily to the overall performance of your server, and it’s essential to track them.

Moreover, monitoring these metrics helps you easily detect performance or resource bottlenecks. Why does this matter? If your server doesn’t have enough CPU power to operate smoothly, CPU usage can lead to a resource bottleneck, causing the whole system’s performance to degrade. It’s important to measure all the hardware metrics because a single component can cause a resource bottleneck.

Server Uptime

The uptime reflects the overall health of the server. An IT service in good health typically has a high server uptime. Many organizations aim for a server uptime of at least 99%, and many companies push it even further to 99.5% or even 99.9% uptime.

Server uptime is important for improving customer experience.

HTTP Server Error Rate

The HTTP server error rate also contributes greatly to customer experience. This metric tells you how often users see an internal HTTP error code or experience an internal server error. Obviously, you want to keep this rate as low as possible; a high error rate undermines the trustworthiness of your service.

You should also track HTTP 5xx error codes because they represent internal errors. These types of errors often have the biggest impact on user experience.

It’s also worth tracking other error codes, such as 404 error codes. When a user sees a 404 error code, it means a page doesn’t exist or the server can’t find the page. Best practices recommend you create alerts to warn you when a user sees a 404 page. It’s one of the easiest errors to track and one of the easiest to fix.

Wrapping Up

I hope you now understand the top metrics to consider when implementing server monitoring. You should use a software tool designed to enable automated server monitoring and real-time data visualizations—AppOptics, for example, offers a free trial of their platform, which supports your automated server monitoring endeavors.

This article covered five important metrics, but you can also measure many other advanced metrics. For example, you can keep track of the thread count for your application. But even though advanced metrics can help you, I suggest starting with the five metrics above. You can easily track these metrics, and they provide you with important information about the performance and health of your server. In other words, try to maximize the return on investment for the metrics you monitor.
