In recent times, dependence on online transactions for daily needs has grown many folds. However the internet is prone to multiple threats. Any organization or any individual who expose their systems on the internet, have to endeavor to safeguard their resources and information by implementing appropriate techniques to circumvent these threats. One such technique is Firewall. In this article let’s learn more about Cybersecurity firewall.
The topics discussed in this article are;
Cyberworld or cyberspace is a market place of all devices and entities that are interconnected using the internet also known the World Wide Web. Communication between different entities in cyberspace, namely, large enterprise systems, financial applications, software as service on the cloud, institutions, small and medium enterprises, self-employed individuals laptops, desktops, mobile applications, are all prone to threats. A threat to an entity in the cyberspace can be:
Large organizations define a trusted network or a defined private workplace of resources that they require to expose to the external world or public networks for a purpose. All their applications and systems published on the internet or the public are placed within this defined perimeter of the organizations trusted network. Organizations are continually on the lookout for improved methodologies to secure these applications from unwarranted threats. A firewall is one such solution placed at the perimeter of the organizations’ internal trusted network where the user gains access to the application.
A cybersecurity firewall is a network security system which can either be a hardware or software that protects the trusted network from unauthorized access from external networks and external threats.
Implementing a firewall does the following things:
Organizations have to implement other mechanisms and controls to circumvent these threats. Threats like, intrusion detection systems and intrusion prevention systems. Attacks from the internet of virus, trojans, spyware, ransomware, denial of service, malware, can be foiled by implementing an antivirus and other prevention and detection systems alongside firewalls.
There are multiple solutions to detect and prevent malicious behavior and attacks. Because there are many ways to avoid attacks a need is felt to find integrated solutions for firewalls, antivirus, anti-spam, and intrusion detection and intrusion prevention. Such solutions will be the next-generation innovation in the field of Cyber Security.
Every commercial or application services exposed on the internet will have its own security requirements based on the functionality. A detailed study and feasibility analysis must be done before implementing the most appropriate of security control systems. To beat the world of threats and hackers, the focus has to be on implementation and then continual improvisations to meet all the possible current and future threats. A firewall is one of the many solutions available in today’s world cybersecurity to control these external threats.
