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.

While we might like to think our networks are perfectly maintained and documented, the reality is sometimes we lose track. In some cases, your network can grow so quickly you may have trouble keeping up. The solution to this issue is using a network discovery tool to ensure your network structure is always documented. This becomes increasingly important if you use combinations of virtual networks, cloud servers, and both wired and wireless networks, as the hybrid network topology can become seriously complex.

To understand this problem a little more, I’ll explain what network discovery is and why it matters, and then I’ll go through the best network discovery tools currently on the market capable of helping you keep track of your network devices. I also review my favorite discovery solution on the market today— SolarWinds®Network Performance Monitor, and explain why its capability to automatically discover and map your network, showing you network connections and topology with the easy-to-read NetPath™ tool, sets this network discovery tool apart from the rest.

What Is Network Discovery?

The first aspect of network discovery is finding all the IP addresses on the network, including static, dynamic, reserved, and abandoned IP addresses capable of being reallocated. The importance of discovering this part of the network is twofold: it helps you to ensure, first, every allocated IP address is valid and isn’t being used by a malicious or rogue device; and second, your network is set up in the most efficient way, by not leaving abandoned IP addresses or subnets to be used for other purposes.

Network discovery determines which ports are in use, and which ports are open on each device. If a device has open ports that aren’t necessary for the device to be used, this could be a security issue. Using network discovery to map the ports on your network can help ensure unnecessary ports are kept closed to prevent access by an intruder.

The next part of the process is figuring out how all the devices on the network are connected, and in which topology. Understanding and mapping the network in this way can help you find bottlenecks and keep track of each device and how it’s performing. Discovering and tracking network performance metrics is vital for ensuring the network is performing well and is free from faults or availability issues.

How Do Discovery Tools Work?

It’s possible to perform network discovery manually, though the risks are mistakes being made and parts of the network not being accurately mapped or monitored. And, without the assistance of network discovery tools, troubleshooting performance issues can be a long and tedious process. Using software to take the pain out of this process will also free you and your team up to focus on other things or to work on improving your network.

Best Network Discovery Software

  1. SolarWinds Network Performance Monitor

Network Performance Monitor (NPM) with network discovery feature from SolarWinds is my top pick for network discovery and management tool. NPM automatically scans your network, and it can show you your entire network topology with a visual mapping tool. Its NetPath function allows you to see pathways from your own network to destination services. These maps can help you pinpoint problems in your network or see issues as they occur, meaning you can troubleshoot issues faster.

In addition to IP discovery, port discovery, and mapping, NPM includes performance monitoring functions to help you put this network information to good use. It also includes security features and alerts and is a scalable, centralized network management tool. NPM offers a free trial so you can try it out, and if you like it as much as I do, you can look at the different levels of paid options available depending on your business size.

  1. SolarWinds Network Topology Mapper

While SolarWinds NPM includes features to measure network performance, SolarWinds Network Topology Mapper (NTM) is purpose-built to focus on mapping networks and can build several different network map types using a single discovery scan.

You can use PRTG Network Monitor as a network discovery and mapping tool, but only using PRTG Map Designer. While this is an excellent network mapping tool, it involves a manual process you’ll need to learn how to do. However, once you’ve created the maps, they’ll display updated network information in real-time for each device, as well as showing you connection data and performance, alongside important status updates. While this is good software, I’d say it’s on the pricier end for what it offers.

If you’re looking for a simple mapping tool, consider trying out Intermapper, offered by HelpSystems. Intermapper includes network performance monitoring capabilities, but this feature is relatively limited. Its primary use is for discovering and mapping your network. The mapping tool automatically discovers your network (including all physical and virtual equipment with an IP address) and creates a customizable map. This map then updates automatically and displays real-time network performance data.

Intermapper has versions available for Windows, Mac, and Linux. It’s available on a cost-per-device basis, or you can pay a flat fee for unlimited devices.

  1. Advanced IP Scanner

When your primary need is network mapping by way of simple IP scanning, Advanced IP Scanner is a good choice. It’s free, so you can use it even if your business doesn’t yet have the funding for a professional tool. It’s made to be used in conjunction with the developer’s Radmin remote administration software, but as a standalone tool, it does the job. It scans and identifies the Windows PCs on your network and can shut down and wake networked computers remotely. The main downside is its limited functionality.
