Network security is a broad term that encompasses a wide range of technologies, devices and processes. With its simple name, set of rules and configurations designed to protect the integrity, confidentiality and access of computer networks and data using both software and hardware technology. Every organization, regardless of size, industry or infrastructure, needs a level of network security solutions to be protected from the ever-growing threat of cyber bullying in the wild today.
Today’s network structure is complex and subject to a constantly changing situation and attackers are constantly trying to detect and exploit the threat. This risk can occur in a wide range of locations, including devices, data, applications, users and locations. For this reason, there are many network security management tools and applications used today that address individual threats and exploitation and lawlessness.
If just a few minutes of rest can cause widespread disruption and serious damage to an important line and organization, it is important that these precautions are taken.
There are many layers to consider when talking about network security across the organization. Attacks can occur in any layer of network layer models, so your computer security software, software and policies should be set up to deal with each location.
Network security usually consists of three different controls: physical, technical and administrative. Here is a brief description of the different types of network security and how each controller works.
Virtual security controls are designed to prevent unauthorized personnel from physically accessing parts of the network such as elevators, cable cabinets and more. Controlled access, such as locks, biometric authentication and other tools, is essential for any organization.
Technological security controls protect data stored on the network or on the road across, in or out of the network. Dual protection; it needs to protect data and programs from unauthorized employees, and it also needs to protect malicious actions from employees.
Management security controls include security policies and procedures that govern user behavior, including how users are authorized, their level of accessibility and how IT staff members implement changes in infrastructure.
We’ve talked about different types of network security controls. Now let’s look at some of the different ways you can protect your network.
Network Access Control
To ensure that powerful attackers are unable to access your network, comprehensive access control policies must be in place for both users and devices. Network access control (NAC) can be set at the most granular level. For example, you can give administrators full access to the network but deny access to certain private folders or block their personal devices from joining the network.
Antivirus and Antimalware Software
Antivirus and antimalware software protects the organization from a list of malicious software, including viruses, ransomware, worms and trojans. The best software not only scans files when it hits the network but continuously scans and tracks files.
Firewalls, as the name implies, serve as a barrier between unreliable external networks and your trusted internal network. Administrators often configure a set of defined rules that block or allow traffic to enter the network. For example, Forcepoint’s Next Generation Firewall (NGFW) provides seamless control and control over network traffic, whether physical, visual or cloud.
Visible Private Networks
Virtual private networks (VPNs) create a connection to a network from another repository or site. For example, users who work from home can often connect to an organization’s network via a VPN. Data between two points is encrypted and the user will need to verify in order to allow connection between his device and the network. Forcepoint’s Secure Enterprise SD-WAN allows organizations to quickly create VPNs using drag and drop and secure all areas with our Next Generation Firewall solution.
