What is network security? It is a good idea to ask your trusted IT partner what they consider as network security. Because small and medium-sized businesses (SMBs) often lack the IT resources of large companies. That means your security may not be sufficient to protect your business from today’s sophisticated internet threats.
Network Security is an organization’s strategy and provisions for ensuring the security of its assets and network traffic. Network security is manifested in an implementation of security policy, hardware, and software.
In answering the question, you should know 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.
- VPN (IPSec & SSL VPN).
- Anti-Virus & Anti-Spyware.
- Web Filtering.
- Bandwidth Management.
- Multiple Link Management.
What Is Network Security and How Does It Protect You?
After asking What is network security?, you should ask, What are the threats to your network?
Many network security threats today are spread over the Internet. The most common include but changing daily:
- Ransom ware.
- Trojan horses, Worms and Viruses.
- Spyware and adware.
- Zero-day attacks, also called zero-hour attacks.
- Hacker and denial of service attacks.
- Data interception and identity theft.
How Does Network Security Work?
It helps to understand that no single solution protects you from a variety of threats. You need multiple layers of network security. If one fails, others still stand. Network security is accomplished through hardware and software. The software must be constantly updated to ensure your security 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?
With 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 customers’ data, it reduces the risk of legal action from data theft.
Ultimately, network security helps protect a business’s reputation, which is one of its most important assets.
