-'''Network Security''' is an organization’s strategy that enables guaranteeing the [[security]] of its assets including all network traffic. It includes both software and hardware technologies. Access to the network is managed by effective network security, which targets a wide range of threats and then arrests them from spreading or entering in the network. Network security is an integration of multiple layers of defenses in the network and at the network. Policies and controls are implemented by each network security layer. Access to networks is gained by authorized users, whereas, malicious actors are indeed blocked from executing threats and exploits.

 Network security is a subgroup of networking. It involves securing the connected network infrastructure from the core to the edge of the network perimeter. Typically managed by a network administrator, network security involves implementing IT security policy and deploying network software and hardware to:
 *Protect the network, its infrastructure and all its traffic from external cyberattacks
 *Protect all IT assets and resources available via the network from unauthorized access

-*Firewalls: Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. They use a set of defined rules to allow or block traffic. A firewall can be hardware, software, or both.
+*[[Firewall]]s: Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. They use a set of defined rules to allow or block traffic. A firewall can be hardware, software, or both.
 *Email security: Email gateways are the number one threat vector for a security breach. Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware. An email security application blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data.
-*Anti-virus and anti-malware software: "Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best antimalware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage.

 *Network segmentation: Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier. Ideally, the classifications are based on endpoint identity, not mere IP addresses. 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 are contained and remediated.
-*Access control: Not every user should have access to your network. To keep out potential attackers, you need to recognize each user and each device. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC).

 *Application security: Any software you use to run your business needs to be protected, whether your IT staff builds it or whether you buy it. Unfortunately, any application may contain holes, or vulnerabilities, that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes.
 *Behavioral analytics: To detect abnormal network behavior, you must know what normal behavior looks like. Behavioral analytics tools automatically discern activities that deviate from the norm. Your security team can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.
-*Data loss prevention: Organizations must make sure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.

 *Mobile device security: Cybercriminals are increasingly targeting mobile devices and apps. Within the next 3 years, 90 percent of IT organizations may support corporate applications on personal mobile devices. Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private.
 *Security information and event management: SIEM products pull together the information that your security staff needs to identify and respond to threats. These products come in various forms, including physical and virtual appliances and server software.
-*VPN: A virtual private network encrypts the connection from an endpoint to a network, often over the Internet. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.

 *Web security: A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. "Web security" also refers to the steps you take to protect your own website.
 *Wireless security: Wireless networks are not as secure as wired ones. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere, including the parking lot. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.

 Network security exists to help your organization protect not only its sensitive information, but also its overall performance, reputation and even its ability to stay in business. Continued operational ability and an intact reputation are two key benefits of effective network security.
-Companies that fall prey to [[Cyber Crime|cyberattacks]] often find themselves crippled from the inside out, unable to deliver services or effectively address customer needs. Similarly, networks play a major role in internal company processes, and when they come under attack, those processes may grind to a halt, further hampering an organization’s ability to conduct business or even resume standard operations. But perhaps even more damaging is the detrimental effect that a network breach can have on your [[Internet Reputation|business’s reputation]].

 Given the rising tide of identity theft and other dangers related to the theft of personal information, many customers are already hesitant when it comes to sharing data with businesses. And if a cyberattack should occur, many of these customers are likely to withdraw in favor of more secure alternatives. After all, why take the risk?
