Networking Security

Network security is the process measures to protect the underlying networking infrastructure from unauthorized access,Threats ,malfunction, misuse, destruction modification, disclosure. 

Network Security Important :-

• operation and implemented on the organisation’s IT systems

• Protecting the data the users and organisation .

• The organisation’s ability to function without any hindrance

How to network security work?

Many layers to consider when Addressing Network security across an organization. Attacks can happen at any layer in the network security layers model, so your network security software, hardware, and policies must be designed to address each area.

Network security typically consists of three different controls

• Physical

• Technical

• Administrative

Physical Network Security

Physical security controls are designed to prevent unauthorized physical acess. Controlled access & biometric authentication and other devices. 

Technical Network Security

Technical security controls protect data is stored on the network .Protection against malicious activities from employees. 

Administrative Network Security

Administrative security controls consist of security policies and processes that control user authentication.

Types of Network Security 

• Application Security
• Firewalls
• Access Control
• Wireless Security
• Intrusion Prevention System
• Virtual Private Networks(VPN)
• Behavioral Analytics
• Email Security
• Web Security
• Data loss prevention

Application Security :- Application security includes the software, hardware and processes that can be used to track. disconnection application attackers can use to infiltrate your network.

Firewalls :- Firewalls are between your internal network and outside networks, such as the Internet. They use a set of defined rules to allow and block traffic. A firewall can be used in hardware and software both type.

Access Control :- Not every user have access to your network. Can set security policies. You can block non-compliant endpoint devices and  give them only limited access. This process is network access control (NAC).

Wireless Security :- Wireless networks are not as secure . Cyber criminals are increasingly targeting your devices and software.You need to control which devices use access your network. 

Virtual Private Networks(VPN) :- Virtual private network connection from an site to site network, often over the Internet. Typically, a remote-access VPN uses DHCP, IPsec,SSL to authenticate the communication between device and network.

Email Security :- Attackers use personal information and social information hack and send them to sites serving up malware. Email security application blocks incoming attacks and controls outcoming attacks.

Web Security :- Web security solution will control your staff’s web use, block threats, and deny access to malicious websites and user wise policy set. It will protect to use firewall.
