Network Security Components for Global

Network security is necessary to prevent unauthorized and unauthorized access to your network, prevent data breaches and protect it from possible cyber threats. While ensuring network security, controls are implemented using various hardware and software solutions at different points within the network. In addition, processes, rules and configurations related to network usage, accessibility and overall cyber threat protection are part of network security. Important categories of network security tools are as follows:

Network Security Firewall

A firewall is a software or hardware product that controls packet traffic to and from the network. It performs access control and macro/micro network segmentation by creating a barrier between your network and external networks.

Network Security Firewalls

• Check Point Next Generation Firewalls (NGFWs)
• Palo Alto Networks Next-Generation Firewall
• FortiGate NGFW
• pfSense

Load Balancing

A load balancer is the process of allocating incoming network traffic among servers, called a server farm or server pool. The allocation process can be equal or it can be performed according to a certain rule. Load balancing improves the performance and reliability of services such as web applications, websites, databases, etc. Systems that perform the balancing process between both application and database servers are called “load balancers”.

Example: Citrix ADC, F5 NGINX Plus

IDS/IPS

IPS (Intrusion Prevent System) and IDS (Intrusion Detection System) are highly reliable intrusion prevention and detection systems developed to prevent and detect cyber attacks. Placed behind a firewall, they provide protocol analysis and signature matching on various parts of the data packet. Most of today’s firewalls support IPS/IDS.

Sandbox

Sandbox is translated into Turkish as sandbox or sandbox. A sandbox is an isolated test environment that allows users to run programs or execute files without affecting the application, system or platform they are working on.

Sandboxing can be divided into two main categories. Sandboxing used in software development and sandboxing used in computer security. Software developers use sandboxes to test software code and cybersecurity experts use sandboxes to test potentially malicious software.

Without sandboxing, an application or other system process can have unrestricted access to all user data and system resources on a network. Sandboxes are also used to safely execute malicious code so as not to harm the device, network or other connected devices on which the code runs. Using a sandbox to detect malware offers an additional layer of protection against security threats such as stealth attacks and vulnerabilities using zero-day vulnerabilities.

NTA/NDR

NTA/NDR looks directly at traffic (or traffic logs such as NetFlow). It uses machine learning algorithms and statistical techniques to assess anomalies and determine whether a threat is present.

NAC (Network Access Control)

NAC is a network security solution built to control access to an organization’s network with defined security policies. Network Access Control (NAC) is a type of cybersecurity technology that controls access to the network by endpoints in an organization, allowing them to define and enforce policies.

Most popular network access control is Forescout.

SIEM

SIEM solutions provide a holistic view of what is happening on a network in real time, enabling IT teams to be more proactive in the fight against security threats. It captures anomalous behavior on the network that the firewall misses.

VPN

VPN uses a combination of many different protocols and technologies. A secure tunnel is established by encrypting the communication between one computer and the other computer on the other side.

Since the data passing through this tunnel is encrypted, your security is ensured because anyone who intercepts or tries to intercept can only see the encrypted data. The better this level of encryption, the more secure your privacy. At the same time, if you put all your data flow (including your DNS requests) in this tunnel, you will have complete protection

EDR (Endpoint Detection and Response)

EDR are tools installed on end-user devices, based on increasing information security and reducing data breaches. In addition to antivirus elements, EDR tools increase the visibility of threats and facilitate forensic analysis with features such as real-time anomaly detection, alerting, tracking and logging of processes running on endpoints.

Network Monitoring

Network Monitoring is one of the indispensable components of the digital world. The concept, which is frequently used in the field of Information Technologies (IT), simply refers to the process of monitoring the performance of all parts connected to a network. Network Monitoring, which confronts IT industry stakeholders as a proactive method, creates significant advantages in both performance and security.
