System and network security is a broad word that encompasses a variety of technologies, equipment, and processes. IT security can be defined as a set of rules and configurations aimed 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 dangers that exist in the real world today.
The network architecture of today is complicated, and it must contend with a threat environment that is always changing, as well as attackers that are constantly looking for and exploiting weaknesses. Users, devices, data, apps, 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 apps are already available for usage. When even a few minutes of the outage may create widespread disruption and significant damage to an organization’s bottom line and reputation, these protection mechanisms must be in place to prevent such consequences.
How does network security work?
When it comes to handling network security throughout a business, 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 rules must be built to address each of these areas.
It is common for network security to be divided into three main types of safeguards: physical, technological, and administrative. Here is a brief overview of the many 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 individuals using physical security mechanisms. Controlled access devices, such as locks, biometric authentication, and other devices, are crucial in any organization’s security strategy.
Administrative 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 persons, as well as against malicious acts carried out by employees.
Technical Network Security
Administrative security controls are made up of security rules and processes that regulate user behavior, such as how users are verified, what level of access they have, and how IT staff members make modifications to the infrastructure.
Types of network security
We have discussed the many types of network security controls that are available. Allow me to walk you through some of the numerous methods you may 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 people 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 offer administrators complete access to the network while denying them access to select confidential folders or disabling their devices from connecting to the network.
The usage of antivirus and antimalware software can defend an organization from a variety of dangerous software, such as viruses, ransomware, worms, and trojan horses. The finest software not only scans and tracks files upon admission into the network but also scans and tracks data on an ongoing basis.
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 construct a set of defined rules that either prohibit or permit traffic to enter the network. Using Forcepoint’s Next-Generation Firewall (NGFW), for example, network traffic may 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.
To connect to a network from another endpoint or site, virtual private networks (VPNs) must be established. Users working from home, for example, would normally connect to the organization’s network over a virtual private network (VPN). Since the data being transmitted between the two places is encrypted, the user would be required to authenticate to permit a connection between their device and the network. Utilizing Forcepoint’s Secure Enterprise SD-WAN, businesses can quickly construct 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 issue for every organization that deals with data and technologies that are connected to a network. In addition to protecting assets and the integrity of data from external vulnerabilities, network security may 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 against the attack and avoid unnecessarily long periods of an outage by utilizing a variety of tools, programs, and services. Forcepoint provides a comprehensive portfolio of network security solutions that centralize and simplify what are typically complex operations while also ensuring that effective network security is in place throughout your company.
