Hardware and/or software that protects a network’s resources from intrusion
Network security is a term that describes the security tools, tactics and security policies designed to monitor, prevent and respond to unauthorized network intrusion, while also protecting digital assets, including network traffic. Network security includes hardware and software technologies (including resources such as savvy security analysts, hunters, and incident responders) and is designed to respond to the full range of potential threats targeting your network.

So, to put it simply, the answer to the question “What is network security?” is this: Network security is the defense you use to protect yourself against ever-increasing cybercrime. It is predicted that by 2021, cybercrime damages will amount to an annual total world cost of $6 trillion, even outpacing the yearly cost of damages attributed to natural disasters. And on an individual company level, these damages can be just as catastrophic. The average cost of a cyberattack is currently $1.67 million, with operational and productivity loss, along with negative customer experience, being the primary consequences of suffering an attack. Optimize your security tools to match today’s threats SHOW ME HOW Your data is the lifeblood of your business: It supports your growth, carries vital resources and helps your organization stay healthy. And if data is blood, then your network is the beating heart that pumps it through your system. But modern cyber threats are like vampires, doing everything possible to get at the blood that keeps your business going. In order to defend against these vampiric threats and save your business from potentially millions of dollars in data loss, you need more than just a stake and some cloves of garlic; you need effective, robust network security and network visibility. In this post, we’ll address the following 14 network security tools:
The Three Key Focuses of Network SecurityWithin network security, there are three key focuses that should serve as a foundation of any network security strategy: protection, detection and response. Protection entails any security tools or policies designed to prevent network security intrusion. Detection refers to the resources that allow you to analyze network traffic and quickly identify problems before they can do harm. And finally, response is the ability to react to identified network security threats and resolve them as quickly as possible. Unfortunately, most businesses simply do not know how to follow policy and do this properly. In fact, in a survey of 4,100 executives, departmental heads, IT managers and other key professionals across the U.S. and Europe, it was revealed that nearly three out of four organizations (73 percent) are fielding a novice-level cybersecurity strategy. This is a growing threat because when network breaches occur and malicious threats come through, there’s more at stake than just the data itself. Benefits of Network SecurityNetwork security tools and devices exist to help your organization protect not only its sensitive information but also its overall performance, reputation and even its ability to stay in business. Continued operational ability and an intact reputation are two key benefits of effective network security. Companies that fall prey to cyberattacks often find themselves crippled from the inside out, unable to deliver services or effectively address customer needs. Similarly, networks play a major role in internal company processes, and when they come under attack, those processes may grind to a halt, further hampering an organization’s ability to conduct business or even resume standard operations. But perhaps even more damaging is the detrimental effect that a network breach can have on your business’s reputation. Given the rising tide of identity theft and other dangers related to the theft of personal information, many customers are already hesitant when it comes to sharing data with businesses. And if a cyberattack should occur, many of these customers are likely to withdraw in favor of more secure alternatives. After all, why take the risk? The loss or corruption of valuable data, along with significant disruption to customer services and internal processes, topped off with reputational injury that may persist long after other damages have been repaired — it’s not hard to see what’s at stake when it comes to network security. In fact, it’s been suggested that 66 percent of SMBs would have to shut down (either temporarily or permanently) after experiencing a data breach. And even larger, more established businesses may be unable to reclaim their former standing. On the other hand, reliable tools in network security software and hardware, coupled with the right policies and strategies, can help ensure that when cyberattacks occur, their impact will be minimal. Network Security Tools and TechniquesYour network faces threats of all shapes and sizes and thus should be prepared to defend, identify and respond to a full range of attacks. But the reality is that the biggest danger to most companies is not fly-by-night threat actors, but rather attackers that are well-funded and are targeting specific organizations for specific reasons. For that reason, your network security strategy needs to be able to address the various methods these actors might employ. Here are 14 different types of network security tools and techniques designed to help you do just that:
Network Security: Let the Sunshine InWhat is network security?
