Simplify IT

When was the last time you thought about network security?

Network security is the process of protecting and preventing unauthorized access and intrusion into corporate networks. This, in turn, protects the integrity and usability of network and data using both hardware and software technologies.

Let’s face it. The only time we think about the network is when it is down or when we are worried about cyber attacks. Keeping your network safe and secure is a 24/7/365 job. Managing a network is one thing. Managing a secure network is another. We have procedures and tools to do both.

Our expert network administrators scan and evaluate your network, fix any security vulnerabilities and put your network on a regular maintenance plan. We keep your firewalls up to date with the latest software, and we perform spot checks and inspections to assure everything is as it should be.

Managing a Secure Network requires experience. We’d be happy to show you how we do it.

Stop worrying about your network.

Let us help. We’ll manage the network, and slam the door if a hacker tries to sneak inside. We’ll report on what we find each month so you can rest easy.


We begin with a complete network inspection. We will do a full security scan, and find any issues that compromise your network security.


We will develop a plan to resolve any security issues. We will correct the problems and lock down your network. We’ll install tracking software to manage performance and security.

Networks and network security

network security

No matter the size, infrastructure, or industry, every organization needs a certain degree of network security to protect from cyber threats.

The way this activity works is by combining more network security layers. So, any malicious attacker is blocked from carrying out threats and exploits, while an authorized user gains access to the network and data. In other words, if hackers can’t get to your computer over the network, they won’t be able to hack it.

There are four types of network, LAN (Local Area Network,) MAN (Metropolitan Area Network,) PAN (Personal Area Network,) and WAN (Wide Area Network.)

CMIT Solutions – Indianapolis routinely works on many types of network security, including firewalls, virtual private networks (VPNs), email security, application security, data loss prevention, mobile device security, antivirus and antimalware software, and network access control.

Is Network Security the Same as Cyber Security?

Cyber security focuses on protecting our system from unauthorized attacks. Network security is a subset of cyber security and focuses on protecting the computer networks and data of organizations, and enterprises using software and hardware systems.

The key differences between network security and cyber security include:

  • Network security protects the data flowing over the network, while cyber security protects the data residing in the servers and devices.
  • Network security protects from DOS attacks, while cyber security protects from cyber-attacks.
  • Network security protects only the transit data, while cyber security protects entire digital data.
  • Network security protects the data travelling across the network by terminals, while cyber security protects the data resting.

How Do Hackers Attack Networks?

The first step in cracking a network’s security is usually finding out the password. Other things hackers do to get in the system include terms like buffer overflow, back door, denial-of-service attack, root access, email worm, root kit, root access, script kindle, Trojan horse, session hijacking, etc.

Network firewall security

Firewalls are network security devices used to monitor outgoing and incoming network traffic and stop or mitigate unauthorized access to an underlying network connected to the Internet. They decide if they are going to block or allow certain traffic based on specific security rules.

Besides protecting computers from incoming network traffic, a two-way firewall protects valuable data from leaving the computer system.

Firewall services decide the type of traffic to which the firewall set of rules applies. Examples of these firewall services are file sharing, web browsing, and remote console access.

Network firewalls are important because they also protect against malware and viruses.

Types of Firewall

The major types of firewall include:

  • Proxy server – serving as a gateway between the Internet and your computer, creating a buffer with the desired webpage. It blocks specific IP addresses or websites, changes or masks your IP address, and encrypts data so that it can’t be read during transmission.
  • Stateful inspection firewall – blocking or allowing traffic based on state, protocol, and port.
  • UTM firewall or unified threat management – combining a firewall with malware, intrusion detection, content filter, and spam protection.
  • NGFW or Next-generation firewall – most advanced firewall technology which examines packets to the app level, in addition to protocol and packet filtering. This type of firewall includes an intrusion prevention system (IPS), deep packet inspection (DPI), stateful inspection, and identity awareness. These features allow blocking of modern threats such as application-layer attacks and advanced malware.

Check Point VPN

This type of network security allows you to connect to your company’s network from your home.

Remote secure access VPN or Check Point VPN allows individual hosts or clients to access a company network remotely and securely. Hosts usually have VPN client software loaded or use a web-based client.

Encryption of all transmitted data, endpoint compliance scanning, and multi-factor authentication ensure the integrity and privacy of sensitive and valuable information.
