What is Network Security?
Network security is the process of taking preventive measures to protect the internet network infrastructure from unauthorized access, misuse, malfunction, alteration, destruction or improper disclosure.
What is Network Attack?
It can be defined as any method, process or tool that tries to compromise network security. Network security is the process of preventing network attacks across a specific network infrastructure, but the techniques and methods used by the attacker vary depending on whether the attack is an active cyberattack, a passive-type attack, or a combination of the two.
Types of Network Security
Since 1991, Comel has been creating solutions that increase efficiency and reduce operation costs with the vision of “SOLUTIONS MANAGING YOUR FUTURE” within the scope of Corporate Business Solutions, System Integration and Information Security for many companies.
Comel, which customizes firewall systems with its own software to ensure network security, secures companies with end-to-end solutions for network security.

How is Network Security Provided?
Antivirus and Anti-Malware Software
This software is used for protection against malware, including spyware, ransomware, Trojans, worms, and viruses. Malware can be very dangerous as it can infect a network and then remain calm for days or even weeks. This software addresses this threat by scanning for malware input and regularly monitors files to detect anomalies, remove malware, and fix damage.
Since no application is created perfectly, it is important to have application security. It is possible that any application consists of vulnerabilities or holes used by attackers to get into your network. Application security thus encompasses the software, hardware and processes you choose to close these holes.
Data Loss Prevention (DLP)
Organizations must ensure that their employees do not send sensitive information outside of the network. Therefore, they should use DLP technologies, network security measures that prevent people from uploading, transmitting and even printing vital information in an unsecure manner.
Email gateways are considered the number one threat vector for a security breach. Attackers use social engineering tactics and personal information to create refined phishing campaigns to deceive buyers and then send them to sites that offer malware. An email security application can block incoming attacks and check outgoing messages to prevent loss of sensitive data.
Firewalls create a barrier between your trusted internal network and untrusted external networks such as the Internet. A set of defined rules is used to block or allow traffic. Firewall can be software, hardware, or both. The free firewall efficiently manages the traffic on your PC, monitors input / output connections and protects all connections when you are online.
Intrusion Prevention System (IPS): IPS is a network security that can scan network traffic to effectively block attacks. The IPS Setup interface allows the administrator to configure ruleset updates for Snort. It is possible to schedule rule set updates to run automatically at certain intervals, and these updates can be run manually on demand.

Mobile Device Security
Mobile devices and apps are increasingly targeted by cybercriminals. 85% of companies will soon be able to support corporate applications on personal mobile devices. You really need to control which devices can access your network. It is also necessary to configure their connections to keep network traffic private.
Software-defined segmentation puts network traffic in various classifications and makes security policies much easier to enforce. Classifications are ideally based on endpoint identity, not just IP addresses. Rights can be accessed based on location, role, and more so the right people get the right level of access and therefore suspicious devices are included and optimized.
Security Information and Event Management
It brings together all the information your security personnel need to identify threats and respond to them. These products are available in different forms, including virtual and physical devices and server software.
VPN is another type of network security that can encrypt connection from an endpoint to a network, mostly over the internet. A remote access VPN typically uses IPsec or Secure Sockets Layer to authenticate communication between the network and the device.
Web Security and Wireless Security
Web Security: An excellent web security solution helps control your staff’s web usage, deny and block access to malicious websites
Wireless Security: The mobile office movement is currently gaining momentum with wireless networks and access points. However, wireless networks are not as secure as wired networks, and this lets hackers in. That’s why it’s so important to have strong wireless security. It should be noted that setting up a wireless LAN without strict security measures can be like placing Ethernet ports everywhere. Products specifically designed to protect a wireless network should be used to prevent abuse from occurring.
Endpoint Security, also known as Network Protection or Network Security, is a method used to protect corporate networks when accessed via remote devices such as laptops or several other wireless and mobile devices.
Network Access Control – NAC
This network security process helps you control who can access your network. It is important to know each device and user to keep potential attackers at bay. This will really help you enforce your security policies. Incompatible endpoint devices can only be given limited access or blocked.
Technical Network Protection: Technical Network Protection is used to protect data within the network. Technical network protection protects stored and transferred data from malware and unauthorized persons.
Physical Network Protection: Physical Network Protection or Physical Network Security is a network security measure designed to prevent unauthorized persons from physically interfering with network components. Door locks and ID cards are essential components of physical network protection.
Administrative Network Protection: Administrative Network Protection is a security method that controls the user’s network behavior and access. It also provides a standard operating procedure for informatics officials while making changes in information infrastructure. Company policies and procedures are forms of administrative network protection.
