There are several ways that cybercriminals can gain access to your network. Rather it is a relentless employee, poor security, no anti-virus protection, or just careless users. Networks security is made up of the hardware, software, policies, and procedures designed to defend against both internal and external threats to your company’s computer systems. Threats to your system can cause viruses, spyware, malware, hacker attacks, Denial of service, even data theft. They thrive for unsecured wireless networks, unpatched software and hardware, unsecured websites, weak passwords, lost devices, and users with malicious intent. Network security involves a lot more to assure your network stays safe from these types of attacks. Such as keeping patches up to date assure that computers are running the most current versions. Making sure your password is strong and hard to guess. Securing your VPN use cloud-based email and file sharing instead of VPN. Creating user-access policies. Make sure employees know how to secure their home wireless networks. Making sure employee usage is user-access assuring that nothing is over looked if an employee is let go make sure that IT is aware and that their access to the network is closed. Network security plays a huge threat at company's but computer hackers are not picky when it comes to what or where they hack into, if it's easy for them to access they will gain entrance and steal what they can.

 As crazy as it sounds but network security was not a major concern when computers were first invented. Important information was not a common thing that was used on computers until late 80s. It was 1988 when the first-automated worm appeared on the ARPANET. Also known as the “Morris Worm”, which was developed by a student at Cornell, exploit the lack of intrusion prevention system and connect to another computer, use vulnerabilities of networked computers- using so many resources that infected computers were rendered inoperable, and spreading quickly throughout the network. That’s when influential leaders in the network decided to developing network security methods to counter against network threats. (www.radware.com/resources/network_security_history.aspx/)  

Network security relies on firewall and anti-virus protection to keep programs running safely and protecting important data information. It is vital in protecting client data and security breaches. A security breach can cost the company thousands and thousands of dollars or loss of clients. Causing a reset in the software and reinstalling operating system. Network security and application security are two distinct things but both require the same basic approach. Network security is about securing assets and scanning traffic at the network level. Such as servers, wireless networks, and routers. Software security is the idea of engineering software so that it continues to function correctly under malicious attack. Software security aims to avoid security vulnerabilities by addressing security from the early stages of software development life cycle. (softwaresecurity-universityofcoloradobouldercomputer)  

Both network and software security are very important and both are needed to assure your network are safely protecting all your network.  

Network security architecture is a governing model that dictates the kinds of security services that should be in place in order to protect the network from both external and internal malicious manipulation and attacks. (www.techopedia.com/definition/29941/network-security-architectrue)
