System and network security is a broad term that encompasses a variety of technologies, devices, and processes. IT security can be defined as a set of rules and configurations designed to protect the integrity, confidentiality, and accessibility of computer networks and data through the use of software and hardware technologies, both software and hardware. Every organization, regardless of its size, industry, or infrastructure, must have some level of network security solutions in place to protect itself from the ever-growing landscape of cyber threats that exist in the real world today.
The network architecture of today is complex, and it must contend with a threat environment that is constantly changing, as well as attackers who are constantly looking for and exploiting vulnerabilities. Users, devices, data, applications, and locations are all examples of places where vulnerabilities can be found in a wide variety of contexts. To address individual threats and exploits, as well as regulatory non-compliance, a plethora of network security management tools and applications are currently available for use. When even a few minutes of downtime can cause widespread disruption and significant damage to an organization’s bottom line and reputation, these protection measures must be in place to prevent such consequences.
How does network security work?
When it comes to addressing network security across an organization, there are numerous layers to consider. At any layer of the network security layers model, an attack can occur, and your network security hardware, software, and policies must be designed to address each of these areas.
It is common for network security to be divided into three different types of safeguards: physical, technical, and administrative. Here is a brief overview of the various types of network security controls, as well as how each one operates.
Physical Network Security
Network components such as routers, cabling cupboards, and other such items are protected against physical access by unauthorized personnel using physical security controls. Controlled access devices, such as locks, biometric authentication, and other devices, are essential in any organization’s security strategy.
Technical Network Security
Protection for data stored on a network as well as data in transit across, into, and out of a network is provided by technical security controls (TSCs). Data and system protection must be twofold: it must protect against access by unauthorized personnel, as well as against malicious activities carried out by employees.
Administrative Network Security
Administrative security controls are made up of security policies and processes that regulate user behavior, such as how users are authenticated, what level of access they have, and how IT staff members make changes to the infrastructure.
Types of network security
We have discussed the various types of network security controls that are available. Allow me to walk you through some of the different methods you can use to secure your network.
Network Access Control (NAC) is a term that refers to the control of access to a network.
Comprehensive access control policies for both users and devices must be in place to prevent potential attackers from infiltrating your network. Network access control (NAC) can be configured to the smallest possible level of detail. It is possible, for example, to grant administrators full access to the network while denying them access to specific confidential folders or disabling their devices from connecting to the network.
Antivirus and antimalware software are two types of software.
The use of antivirus and antimalware software can protect an organization from a variety of malicious software, such as viruses, ransomware, worms, and trojan horses. The best software not only scans and tracks files upon entry into the network but also scans and tracks files continuously.
Protection from the Internet via a firewall
Firewalls indeed serve as a barrier between your trusted internal network and untrusted external networks, as their name implies. Typically, network administrators configure a set of defined rules that either block or permit traffic to enter the network. Using Forcepoint’s Next-Generation Firewall (NGFW), for example, network traffic can be controlled in a seamless and centrally managed manner regardless of whether it is physical, virtual, or in the cloud.
VPNs (Virtual Private Networks) are a type of network that allows you to connect to the internet anonymously.
In order to connect to a network from another endpoint or site, virtual private networks (VPNs) must be established. Users working from home, for example, would typically connect to the organization’s network through a virtual private network (VPN). Since the data being transmitted between the two points is encrypted, the user would be required to authenticate to permit communication between their device and the network. Using Forcepoint’s Secure Enterprise SD-WAN, businesses can quickly create VPNs using drag-and-drop functionality, while also protecting all of their locations with our Next-Generation Firewall solution.
Network security for businesses and consumers
Network security should be a top priority for any organization that deals with data and systems that are connected to a network. In addition to protecting assets and the integrity of data from external exploits, network security can also improve the efficiency with which network traffic is managed, the performance of networks, and the ability to securely share data between employees and information sources.
It is possible to protect your networks from attack and avoid unnecessarily long periods of downtime by utilizing a variety of tools, applications, and utilities. Forcepoint provides a comprehensive suite of network security solutions that centralize and simplify what are often complex processes while also ensuring that robust network security is in place throughout your enterprise.
