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 Definition And Meaning
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.
Our world has presently been transformed by digitization, resulting in changes in almost all our daily activities. It is essential for all organizations to protect their networks if they aim at delivering the services demanded by employees and customers. This eventually protects the reputation of your organization. With hackers increasing and becoming smarter day by day, the need to utilize network security tool becomes more and more impotent.
Types of Network Security
- Antivirus and Antimalware Software
- Application Security
- Behavioral Analytics
- Data Loss Prevention (DLP)
- Email Security
- Mobile Device Security
- Network Segmentation
- Security Information and Event Management (SIEM)
- Virtual Private Network (VPN)
- Web Security
- Wireless Security
- Endpoint Security
- Network Access Control (NAC)
Antivirus and Antimalware Software : This software is used for protecting against malware, which includes spyware, ransomware, Trojans, worms, and viruses. Malware can also become very dangerous as it can infect a network and then remain calm for days or even weeks. This software handles this threat by scanning for malware entry and regularly tracks files afterward in order to detect anomalies, remove malware, and fix damage.
Application Security: It is important to have an application security since no app is created perfectly. It is possible for any application to comprise of vulnerabilities, or holes, that are used by attackers to enter your network. Application security thus encompasses the software, hardware, and processes you select for closing those holes.
Behavioral Analytics: In order to detect abnormal network behaviour, you will have to know what normal behavior looks like. Behavioral analytics tools are capable of automatically discerning activities that deviate from the norm. Your security team will thus be able to efficiently detect indicators of compromise that pose a potential problem and rapidly remediate threats.
Data Loss Prevention (DLP): Organizations should guarantee that their staff does not send sensitive information outside the network. They should thus use DLP technologies, network security measures, that prevent people from uploading, forwarding, or even printing vital information in an unsafe manner.
Email Security: Email gateways are considered to be the number one threat vector for a security breach. Attackers use social engineering tactics and personal information in order to build refined phishing campaigns to deceive recipients and then send them to sites serving up malware. An email security application is capable of blocking incoming attacks and controlling outbound messages in order to prevent the loss of sensitive data.
Firewalls: Firewalls place a barrier between your trusted internal network and untrusted outside networks, like the Internet. A set of defined rules are employed to block or allow traffic. A firewall can be software, hardware, or both. The free firewall efficiently manages traffic on your PC, monitors in/out connections, and secures all connections when you are online.
Intrusion Prevention System (IPS): An IPS is a network security capable of scanning network traffic in order to actively block attacks. The IPS Setting interface permits the administrator to configure the ruleset updates for Snort. It is possible to schedule the ruleset updates allowing them to automatically run at particular intervals and these updates can be run manually on demand.
Mobile Device Security: Mobile devices and apps are increasingly being targeted by cybercriminals. 90% of IT organizations could very soon support corporate applications on personal mobile devices. There is indeed the necessity for you to control which devices can access your network. It is also necessary to configure their connections in order to keep network traffic private.
Network Segmentation: Software-defined segmentation places network traffic into varied classifications and makes enforcing security policies a lot easier. The classifications are ideally based on endpoint identity, not just IP addresses. Rights can be accessed based on location, role, and more so that the right people get the correct level of access and suspicious devices are thus contained and remediated.
Security Information and Event Management (SIEM): SIEM products bring together all the information needed by your security staff in order to identify and respond to threats. These products are available in different forms, including virtual and physical appliances and server software.
Virtual Private Network (VPN): A VPN is another type of network security capable of encrypting the connection from an endpoint to a network, mostly over the Internet. A remote-access VPN typically uses IPsec or Secure Sockets Layer in order to authenticate the communication between network and device.
Web Security: A perfect web security solution will help in controlling your staff’s web use, denying access to malicious websites, and blocking
Wireless Security: The mobile office movement is presently gaining momentum along with wireless networks and access points. However, wireless networks are not as secure as wired ones and this makes way for hackers to enter. It is thus essential for the wireless security to be strong. It should be noted that without stringent security measures installing a wireless LAN could be like placing Ethernet ports everywhere. Products specifically designed for protecting a wireless network will have to be used in order to prevent an exploit from taking place.
Endpoint Security: Endpoint Security, also known Network Protection or Network Security, is a methodology used for protecting corporate networks when accessed through remote devices such as laptops or several other wireless devices and mobile devices. For instance, Comodo Advanced Endpoint Protection software presents seven layers of defense that include viruscope, file reputation, auto-sandbox, host intrusion prevention, web URL filtering, firewall, and antivirus software. All this is offered under a single offering in order to protect them from both unknown and known threats.
Network Access Control (NAC): This network security process helps you to control who can access your network. It is essential to recognize each device and user in order to keep out potential attackers. This indeed will help you to enforce your security policies. Noncompliant endpoint devices can be given only limited access or just blocked.
Technical Network Protection: Technical Network Protection is used to protect data within the network. Technical network protection guards both stored and in-transit data from malicious software and from unauthorized persons.
Physical Network Protection: Physical Network Protection, or Physical Network Security, is a network security measure designed to prevent unauthorized people from physically interfering with network components. Door locks and ID passes are essential components of physical network protection.
Administrative Network Protection: Administrative Network Protection is a security method that control a user’s network behaviour and access. It also provides a standard operating procedure for IT officers when executing changes in the IT infrastructure. Company policies and procedures are forms of Administrative network protection.
