What is Network Security??
Network security is the protection provided to the network from Unauthorized Access and Risk. It protects your network and data from breaches, intrusions and other threats. It includes both hardware and software technology. This prevents them from entering or spreading on your network. Effective Network Security manages access to the network.
How does Network Security Prevent Threats ??
Malware
Adware
Botnets
Computer worms
Trojan horses
spyware
Distributed denial-of-service attacks
ransomware
How does Network Security work??
An organization has many layers to consider when addressing Network Security. Attacks can occur at any layer in the network security layer’s model, so your network security hardware, software, and policies must be designed to address each area.
Network Security combines multiple layers of rescue over the edge and into the network. Each Network Security Layer enforces policies and controls. Authorized users gain access to network resources, but Malicious Actors are prevented from committing exploits and threats.
Benefits of Network Security
It helps to protect the important personal data of clients available in the network.
To help secure the secure information available on all computers in a single network.
It ensures to protect all physical machines in the same network from hacking attack or any kind of malware or virus related attack through open internet.
Enables a more modern workplace.
Protects proprietary information.
Reduces risk.
Creates trust.
Types of Network Security
1)firewall
A firewall has put a barrier between your trusted internal network and an external network such as the Internet. They use a set of Defined Rules to allow or block the rules of Traffic. A firewall can be hardware, software, or both.
Firewalls exist as software running as a software and hardware devices. Firewalls that are hardware-based also provide other functions such as acting as a DHCP server for that network.
Most personal computers use software-based firewalls to protect data from threats from the Internet. Firewalls are the main component in many routers that pass data between networks and, conversely, many firewalls can perform basic routing functions.
Firewalls are commonly used in private networks or intranets to prevent unauthorized access to the Internet. Every message entering or leaving the intranet goes through firewalls to check security measures.
2) Antivirus and Antimalware Software
Antivirus and Antimalware Software protect an organization from a range of malicious software including viruses, ransomware, worms and Trojans. The best software not only scans files upon entry into the network, but also scans and tracks files continuously.
3) Email security
Email security refers to any process, products and services designed to protect your email accounts and email content from external threats.
Most email service providers have built in email security features designed to keep you safe, but these may not be enough to prevent cybercriminals from accessing your information.
4) Virtual Private Networks (VPN)
Virtual Private Networks (VPN) make a connection to the network from another end point or site. For example, users working from home typically connect to the organization’s network over a VPN. The data between the two points is encrypted and the user will need to authenticate to allow communication between their device and the network.
5) Network segmentation
Software-defined segmentation puts network traffic into different classifications and makes it easier to implement security policies. Ideally, classifications are based on Endpoint Identity, not just IP Address. You can assign access rights based on role, location and more so that the right level of access is given to the right people and suspicious devices can be contained and remedied.
6) Access Control
The most common security issue is unauthorized access to computer systems. Generally, this is for collecting Access information or for malicious changes to the database. The security mechanism of a DBMS should include provisions to completely restrict the database system. This function is called Access Control.
The purpose of an access control system is to control the actions performed by users to prevent actions that may harm data and resources.
The usual way to implement Access Control in Database System is dependent on Database Granting and Revoking Privileges. A privilege allows a user to create certain database objects or run certain DBMS utilities.
7)Data loss Prevention
Data loss prevention (DLP) is the practice of detecting and preventing data breaches, exfiltration or unwanted destruction of sensitive data. Organizations use DLP to protect and protect their data and follow the rules.
8) Intrusion prevention system
An intrusion prevention system (IPS) is a network security/threat prevention technology that examines network traffic flows to detect and prevent vulnerability exploits.
9) Wireless Security
Unwanted prevents users from accessing a particular wireless network. In addition, wireless security, also known as Wi-Fi security, aims to ensure that your data remains accessible only to users you authorize.
10)sandboxing
Sandboxing is a software management strategy that isolates critical system resources and applications from other programs. It provides an additional layer of protection that prevents malware or harmful applications from negatively affecting your system.
