Network security has become a rising concern for many companies who have digitized much of their information and services. Having top-notch security that is multi-layered with various types of security options is ideal to keep malicious data thieves out.
1. Antivirus / Antimalware
Malicious programs, such as viruses, Trojans, ransomware, worms, and spyware, can infect your entire network. It’s important to realize that these programs may lay dormant for weeks on your network before attempting to steal or alter information. With a good antimalware and antivirus software, you can close these easy loopholes into your network.
Firewalls act as a barrier between your own trusted network and any untrusted networks outside of yours. A specific algorithm is employed with each firewall which determines whether to block or allow the traffic. Most systems will come with a firewall installed and you can customize the firewall to define an algorithm you feel safe with.
VPNs, also known as virtual private networks, allow for encryption of connections from an endpoint to your network when using the internet. The VPN will use a Secure Sockets Layer or IPsec to authenticate the connection between the device being used and your network.
4. Web Security
A good web security solution will prevent your employees from accessing websites that are deemed malicious. This type of security can control web use in many other ways as well to keep the chance of unwanted threats very low.
5. Wireless Security
Many businesses are using wireless LAN connections instead of traditional wired connections. It’s important to realize that wireless networks are less secure than wired ones. You need to have the proper security setup to avoid unauthorized individuals from connecting to your network via your wireless LAN signal.
6. Network Segmentation
Not everyone in your company is going to need access to all areas of your network. By instituting network segmentation you can assign limited access rights based on the person’s role, location, and other factors. This will ensure that your employees are only given access to the specific parts of the network that constitute to their job getting done effectively.
Allowing employees full access to all areas of your network is unnecessary and increases the potential for data loss threats. If you use a managed hosting service, the threat level is significantly reduced since you have greater control over which areas of your network are segmented.
7. Email Security
Email is one of the most commonly abused areas when it comes to network security. Many sophisticated phishing emails can be sent to your employees with the intention of deceiving the recipient into visiting a linked out to malicious website.
Email security allows you to pre-screen email threats and contain them. In addition, this type of security application can prevent the loss of sensitive data by controlling the outbound messages sent by your employees.
