With a colossal surge in cyber-attacks and high reliance on technology in this digital age, ensuring the security of data and information have become a daunting task. Cyber threats are accelerating significantly even faster than the enhancements businesses are making. Computer networks have become bigger and their interconnectivity using a Wide Area Network (WAN) is worldwide due to globalization. It is hard for current IT security solutions to prevent cyber-attacks. According to Symantec’s 2019 Internet Security Threat Report (Volume 24), Formjacking attacks compromised 4800+ websites almost every month. Supply chain attacks also increased by 78% in 2018. Furthermore, more than 70 million records were also leaked or stolen due to poor configuration of S3 buckets.
SANS institute defines Network Security as the preventative measures taken to safeguard network infrastructure from unauthorized access, modification, malfunction, misuse, improper disclosure or destruction of data.
There is a significant need for network security in a computing environment to protect data and information from unauthorized users. There are three key components of any network security that must be in place. These are Confidentiality, Integrity, and Availability, also known as CIA triad. Confidentiality ensures that the data is not intercepted by hackers when it is being transmitted on a network. Integrity makes sure that data is not changed, damaged, or manipulated during the transmission over a network. Availability is also a security service that ensures that the systems and devices are available only to authorized parties.
There are a lot of practices that must be applied by organizations in order to prevent attacks on a network. The following sections elaborate on these practices in details.
This research article is based on ensuring network security in a computing environment. The researcher pointed out the various attributes which are highly significant to protect data and information from unauthorized users. As a result, it is evident that cyber threats are greater in number and sophistication and, therefore, networks are vulnerable to these notorious attacks. However, if organizations take some proactive measures, then network security can be ensured.
