One of the most crucial aspects of network security is protecting clients’ data and information with a well-designed security solution. The goal is to reduce overhead expenses while safeguarding organizations from data breaches and malicious activities over the internet. An efficient security management system in any network, be it public or private, can help achieve these milestones to a great extent.
Based on data collected by finances online, the global cybersecurity market is to reach a value worth US$ 352 billion, increasing at a rate of 14.5% by the year 2026. Cybercrimes, in contrast, will continue to grow exponentially. To encounter these, let’s explore some of the different types of cybercrimes and the advantages of network security protocols.
The different types
Internet use is increasing drastically daily – transforming our activities towards complete digitization. This has opened doors for hackers to infiltrate networking systems, and we tend to see a higher number of virus attacks every year. Businesses across the globe need to structure a networking shield to protect their systems from cyber-attacks.
Some of the network security types are:
1. Antivirus/Malware Software
The software that protects our systems from malware and trojan attacks is an antivirus. It scans the whole system and network, looks for possible threats that can harm it, and helps fix the problem if the virus is detected upon scanning.
2. Employing DLP technology
Big enterprises maintain data confidentiality by ensuring that employees do not leak any information to the outside world. For this, a DLP technology is deployed where the network administrator is responsible for restricting employees access to certain information by blocking different ports and sites.
3. Securing Emails
A hacker can quickly induce malware into the network through an email in the system. Therefore, companies need highly skilled email security systems to scan the email for any incoming viruses and filter out suspicious data.
4. Building firewalls
Firewalls act as a wall between two networks or devices. They are made up of some predefined rules to prevent unauthorized access consisting of two kinds:
- Software: These firewalls act as provision shields to filter and block unwanted threats.
- Hardware: This type acts as a gateway between networks and only allows pre-defined traffic to access the network’s resources.
Organizations segment their crucial data and keep them in two to three different locations for its security, so in the worst-case scenario, at any one time, only one site is corrupted or deleted. They can then easily recover and reconstruct data from other available resources.
6. Mobile Security
Hacking into employees’ mobile devices is very easy for hackers. They can use an unsecured link from a website and prompt the user to click on it. Hence, these devices must have an antivirus installed from reliable and secured websites for protection against malware.
7. Access Control
Networks should be designed in such a way that not everyone can access all the resources by deploying unique ID and authentication processes for every individual – known as access control.
8. Virtual Private Network (VPN)
VPN networks developed in association with encryption methods for authentication like IPSec build a highly secure network for data exchange. The communication channel is encrypted for protecting data traffic from malware and threats.
What will network security protect against?
There are so many various methods by which a malicious user can try to attack your network. NordLayer enterprise network security will help you build a robust network security solution and protect against the following types of malware:
A virus is a malicious file that can replicate itself to change the code of a computer program with its code. After infecting a file, the virus can spread from one computer to another, destroying networks and data.
As the name suggests, worms eat up the bandwidth of your system and slow down its data processing efficiency. They work independently, unlike a virus that needs a host file to propagate.
They help in building a backdoor as an entryway for malicious users so they can access computer systems by what looks like a program but is, in actuality, harmful to your system. It can delete files and can activate other malicious malware like viruses.
This type of malware spies on users without them knowing and sends useful collected information to a third party without their consent.
Adware redirects to different advertising websites to collect marketing data about the users. After the required information is collected, they bombard consumers with several customized advertisements based on their search and buying history.
In today’s era of collaborative workplaces, where we constantly share confidential information with workers inside the company, keeping files free from infection is particularly important. Using the right tools for network security can minimize the risk of attacks and breaches.
Network security keeps sensitive data away from unauthorized individuals offering additional advantages for the company’s business operations. Investing in this multi-level technology that can sift through oceans of data to protect our systems is the right way for enterprise-level companies to a win-win situation in this highly competitive marketplace.
