In answering the question “What is Network Security?” your IT partner should explain that network security refers to any activities designed to protect your network. Specifically, these activities protect the usability, reliability, integrity, and safety of your network and data. Effective network security targets a variety of threats and stops them from entering or spreading on your network.

What Is Network Security and How Does It Protect You?

After asking what is network security? You should ask, what are the threats to my network? Many network security threats today are spread over the Internet. The most common include:

  • Viruses, worms, and Trojan horses
  • Spyware and adware
  • Zero-day attacks, also called zero-hour attacks
  • Hacker attacks
  • Denial of service attacks
  • Data interception and theft
  • Identity theft

How Does Network Security Work?

To understand What is network security?, it helps to understand that no single solution protects you from a variety of threats. You need multiple layers of security. If one fails, others still stand.

Network security is accomplished through hardware and software. The software must be constantly updated and managed to protect you from emerging threats.

A network security system usually consists of many components. Ideally, all components work together, which minimizes maintenance and improves security.

Network security components often include:

  • Anti-virus and anti-spyware
  • Firewall, to block unauthorized access to your network
  • Intrusion prevention systems (IPS), to identify fast-spreading threats, such as zero-day or zero-hour attacks
  • Virtual Private Networks (VPNs), to provide secure remote access

What are the Business Benefits of Network Security?

With network security in place, your company will experience many business benefits. Your company is protected against business disruption, which helps keep employees productive. Network security helps your company meet mandatory regulatory compliance. Because Network security helps protect your data, it reduces the risk of legal action from data theft.

Fortinet’s flagship Network Security platform, FortiGate, consists of physical and virtual appliances that provide a broad array of security and networking functions, including firewall, VPN, anti-malware, intrusion prevention, application control, Web filtering, anti-spam, DLP, WAN acceleration, and WLAN control. FortiGate appliances, from the FortiGate 30D and 90D for small businesses all the way up to the FortiGate 3000 and 5000 series for large enterprises, data centers, and service providers, are based on a common proprietary technology platform:

  • FortiGuard – Our large global threat research team discovers new threats and delivers protective services 24×365 across a rich array of consolidated security technologies, including application control, intrusion prevention, Web filtering, vulnerability management, anti-malware, anti-spam and more. By developing and delivering all of our threat research and protection services in-house, we provide you with the fastest and most integrated response to threats. FortiGuard protection is independently validated as highly effective versus today’s advanced threats.
  • FortiASICs – Our custom designed ASICs accelerate processing of security and networking functions, to radically boost performance and scalability and provide you with the fastest network security appliance performance available today. This allows you to stay ahead of rapidly growing bandwidth requirements, and prevents your security solution from becoming a choke point in your network.
  • FortiOS – Our proprietary operating system provides the foundation for and integration of all security and networking functions. This allows IT managers to deliver consistent and coordinated policies across all security devices, creating a faster and more robust response to threats with a far lower administrative burden. Flexible licensing of FortiOS features gives you the flexibility to deploy what you need, where you need it — leading to a simpler, easier to maintain infrastructure as well.
  • FortiManager/FortiAnalyzer/FortiCloud – Our easy-to-use management platform — available in hardware appliance, virtual machine, and cloud form factors — provides centralized configuration, security policy management, aggregate logging, reporting, and forensic analysis for up to 10,000 Fortinet devices.

By integrating and accelerating multiple proprietary security and networking functions with purpose-built FortiASIC and FortiOS, delivering dynamic proprietary security service updates via FortiGuard, all managed through a simple comprehensive management console, Fortinet’s network security platform delivers broad protection against dynamic security threats while reducing the operational burden, response time, and costs associated with managing multiple point products.
