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.

Network speed is critical for ensuring business productivity, and network analysis is how businesses can best ensure networks are performing well. But network analysis can be challenging and time-consuming without the right tools. A multitude of factors can contribute to network problems, and effective network analysis requires your IT team to continuously monitor these individual factors to ensure each is performing as it should be. This includes checking Wi-Fi signal strength, network connections, routers, servers, network speeds, and more.

This guide will help you understand what network analysis is and why it’s important, in addition to outlining the main types of network problems and how you can resolve them. Leveraging network performance analysis software can help your team identify and fix network issues both time-efficiently and reliably. With the right network analysis tools, your business can proactively monitor bandwidth availability, network bottlenecks, Wi-Fi speeds, and much more.

For enterprise-grade, user-friendly network performance analysis software, we recommend SolarWinds® Network Performance Monitor (NPM), SolarWinds Bandwidth Analyzer Pack, and SolarWinds NetFlow Traffic Analyzer (NTA). Each of these tools delivers a comprehensive range of utilities designed to give your business in-depth insight into its networks.

What Is Network Analysis?

Network analysis, also called network performance analysis, is an umbrella term referring to closely monitoring or examining network components to discover what might be impacting the overall performance of the network.

To effectively analyze network problems and identify the root cause, network analysis tools decode data traversing your network. This data is then displayed in a simplified and readable way. Network analysis solutions are typically able to help admins perform the following tasks:

  • Network issue troubleshooting
  • Identifying bandwidth bottlenecks
  • Determining the availability and speed of Wi-Fi
  • Identifying instances of spyware or network intrusion
  • Determining which network components have been targeted by DDoS attacks, as well as the source of the attacks
  • Identifying faulty hardware or applications

In some cases, a network analysis tool will be installed as software on a device, as a part of a network. Sometimes, however, the solution will be designed as standalone hardware, which features pre-installed software. Although network analysis tools serve similar purposes, each tool is likely to focus on different parts of the network. When choosing a network analysis tool, you should consider the number of protocols the tools can decode, the user-friendliness of their interfaces, and how comprehensive their data analysis capabilities are.

Why Is Network Analysis Important?

Network analysis can help ensure business productivity and a good user experience by providing insights into a range of performance issues, including security issues that could impact performance.

Effective and proactive network analysis is crucial because it enables businesses to maintain fully optimized and efficient networks by identifying performance problems before they impact the network’s performance. Network analysis is especially important if your organization depends on web-based or cloud-based systems, or if you have a substantial Wi-Fi network with many users. If your network experiences an issue, the impact can range from reduced productivity to lost revenue and damaged reputation.

What Are Some Types of Network Problems?

What Are Some Types of Network Problems

Networks are complicated, and an enormous number of factors can contribute to network performance issues. Here are just a few of the most common network problems.

  1. Duplicated IP Addresses

This occurs when two machines both try to use the same IP address. When this happens, you’re likely to see an error message reading “Address Already in Use.” This will mean you won’t be able to access the network.

  1. DNS Issues

When DNS problems happen, you may see the following messages:

  • IP Address Could Not Be Found
  • The Network Path Cannot Be Found
  • DNS Name Does Not Exist

In these cases, the issue is usually caused by an error in a DNS configuration.

  1. No Workstation Network Connection

If a single workstation cannot connect to the internet, this usually means the issue isn’t with the wider network, but with a specific piece of hardware or software on the workstation’s system.

  1. Inability to Connect With Printer Shares or Local File

Sharing issues are one of the most challenging network issues to resolve, because so many elements must be configured correctly to facilitate sharing. Sharing issues are usually caused by conflicts across different security environments. For example, alternative editions of an operating system might use different security systems or models, which may cause problems when establishing workstation interconnections.

  1. Local Network Can’t Connect to the Internet

Difficulty connecting to the internet may either be a persistent issue or an occasional issue. The most challenging part of rectifying an external network issue is you first have to identify which company is responsible. You will then need to ensure they solve the problem quickly. Intermittent network connection issues are especially hard to trace. If problems of this nature occur regularly, businesses may be forced to change internet providers.

  1. Slow Internet

Typically, slow internet is caused by congestion, or perhaps poorly performing connections that have deteriorated or corroded over time. If you are experiencing slow internet, keep in mind the cause of congestion might not be bandwidth exhaustion—for example, a single overloaded router or switch port could be responsible for diminished network performance.

How to Reduce Network Issues and Problems

Network analysis can be proactive, reactive, or a combination of the two. Reactive network performance analysis involves experiencing or being made aware of poor network performance, then conducting network issue analysis to identify the root cause of the problem. For example, if cloud server and web-based aspects of a network seem to be slow, a business might use network analysis to check for Wi-Fi issues.

Proactive network analysis involves conducting ongoing monitoring activities, often enabling you to get ahead of network issues before they noticeably impact network performance. Proactive network issue analysis is much more effective than reactive network issue analysis, because it helps prevent network issues from escalating and can safeguard your business’ reputation. If you analyze network problems purely reactively, once you’re beginning to experience or receive reports of lagging systems or unresponsive services, then this is likely to impact customer satisfaction. Because of this, businesses should invest in tools designed to facilitate proactive network analysis.

What Aspects of a Network Should Be Analyzed?

To achieve comprehensive network performance analysis capable of protecting your network’s continuity, we recommend continuously monitoring the following network components:

  • Network device availability (i.e., routers, switches, servers)
  • Availability of critical network services
  • Disk space availability on key servers
  • Average percentage of maximum throughput for routers
  • Average processor and memory utilization of key servers/CPUs
  • The status of firewalls, servers, malware defenses, firewalls, and antivirus protection, to ensure all are configured correctly and up to date
  • How much traffic is passing through your routers
  • Events being written to event logs
  • SNMP traps
  • Windows servers and applications
  • Bandwidth availability
  • Traffic patterns
  • Average latency

This list is by no means exhaustive. When choosing a network analysis tool, you should consider not only which network components the tool monitors, but how it displays its analysis. Data should be easy to interpret and engage with and provide targeted insight into network issues.
