Overview
Network security covers a technological multitude of processes and devices. It defines itself as a set of rules and configurations to protect the integrity, confidentiality, and accessibility of computer networks and data. Regardless of size, industry, or infrastructure, an organization requires a degree of network security solutions to protect it from the landscape of cyber threats in the wild today.
The network architecture is complex. It faces a threat environment that is constantly changing and attackers that are always trying to find and exploit vulnerabilities. These vulnerabilities can exist in many areas, including devices, data, applications, users, and locations. For this reason, many network security management tools and applications are in use today that address individual threats, exploits, and regulatory non-compliance. However, when just a few minutes of downtime can cause widespread disruption and massive damage to an organization’s bottom line and reputation, these protection measures must be in place.
Security Approach
There are layers to consider when addressing network security across an organization. Unfortunately, the layered network security model is not entirely safe and secure against cyberattacks and malware. Instead, it requires safety measures, so your network security hardware, software, and policies must be designed to address each area.
NETWORK SECURITY incorporates physical, technical, and administrative controls.
Physical security controls unauthorized physical access to network components such as routers, cabling cupboards, etc. It also functions on Controlled access, such as locks, biometric authentication, and other devices, which is essential in any organization.
Technical security controls protect data stored entirely across or into the networks. Protection is twofold. It tends to preserve and conserve data from unauthorized personal access, and it also needs to protect the data from any malicious activity by an employee.
Administrative security controls include security policies and processes that control user behavior, including how users are authenticating their level of access and how IT staff members implement changes in the architecture of the network.

Antivirus and antimalware software enable a shield of protection around an organization from various malicious software, viz., VIRUS, TROJAN, RANSOMWARE, and WORMS. The best software repeatedly scans and tracks files and keeps the system secure.
As their name suggests, firewalls are a barrier between untrusted external networks and your trusted internal network. Administrators typically configure defined rules that block or permit traffic onto the web. For example, TSARO LABS offers seamless and centrally managed network traffic control, whether physical, cloud, or virtual.
Network security is always highly prioritized for any organization that works with networked data and systems. In addition to protecting assets and data integrity from external exploitation, network security also manages network traffic more efficiently, enhances network performance, and ensures secure data sharing between employees and data sources.
Many tools, applications, and utilities are available to help you secure your networks from attack and unnecessary downtime. In addition, TSAROLABS offers a suite of network security solutions that centralize and simplify complex processes and ensure robust network security at your enterprise
Testing
Pen testing is commonly done in the network infrastructure of a company. It can focus on internal infrastructures or external infrastructure. The attacker focuses on perimeter protection in an external test, like bypassing a next-generation firewall (NGFW).
Web applications may overlap with network services; a web application test is much more detailed, intense, and time-consuming. Web Applications are complex and are publically available for Businesses. As a result, most of the external attack surface is composed of web applications. Some web applications are vulnerable on the server-side, while some are on the client-side. Web Applications are costly and lengthy but are crucial to a business. Web Application includes SQL injection, cross-site scripting, insecure authentication, and weak cryptography .
Wireless testing is done to find vulnerabilities in wireless networks. Wireless pen testing is important to identify and exploit insecure wireless configuration and questionable authenticity because invalid formats may allow users to access a wired network from outside the building. Additionally, businesses are using mobile phones but are unable to secure them. Wireless pen-testing creates a safer place for the employees to use their devices securely.
This text stimulates Phishing, baiting, and pretexting through which a link generates and is sent to the employees of a business to take compromising actions for the company. The Link is created, so that clicking on it provides all the access to the company's information and downloads malware to crash the system. The Social Engineering test helps to understand the employees' susceptibility to such attacks.
Physical PenTesting helps to achieve a physical security test of their organization. In this test, the hacker tries to access the building via discarded papers and credentials that can be used to breach the security code. After getting inside the building, the attacker attempts to avail more information by eavesdropping and hiding rogue devices in the office to gain access to the business's Internal Network. Digital security is prioritized by the IT sector and will be of no use if all the information is passed to any outsider by the business. Therefore, securing the data and providing access only to its employees is very important for a company to safeguard all its pieces of information.
