Cases of cybercrimes, such as hacking, has increased all over the world and costs organizations and individuals millions of dollars. These malicious activities have breached the integrity and confidentiality of data stored on a computer transmitted through a network. The use of firewalls and data encryption are some of the techniques used to secure the data. However, the methods differ in how they offer protection. This paper discusses the difference between firewall protection and encryption protection of information.
Firewall protection is a network device that blocks traffic on a network, creating a barrier between a trusted network and untrusted networks. It is usually located between a local and public network to create a block for intruders as they try to access information from the system (Spasic & Dihovicni, 2019) . It safeguards an organization’s network and keeps monitoring the systems and keeping logs that alert an individual if there is an intrusion (Schafer, 1997) . Firewalls aim at preventing the spread of attacks on a computer. The firewall ensures that some computer ports that are being unused are closed and regulate the most used ports on the computer. Firewall protection divides the network into a trusted zone and an untrusted sites. It controls the internet connections by granting permission to specific traffic to pass through and exit. For example, an organization can set up a network that accepts files within their systems but rejects other files outside the organization.

On the other hand, the encryption technique is the process of encoding data such as files to make it unreadable. The technique applies an algorithm for encrypting data, and then keys for the receiving party for decrypting the information. Information is encrypted into a cyphertext, and the cryptographic technique is used to keep the data secure from access (Wong, 1996) . The encryption technology ensures that the data is meaningless to unauthorized parties. For example, when a person wants to send a confidential email to another party, he/she can use a program that obscures its content such that the other party can only read it.
The most effective data protection technique for data protection, I believe, is the encryption technique. It allows one to securely protect data that you don't need other people to gain access to. It encrypts information making it unreadable to other people except for the intended party; therefore, it can’t be stolen as its meaningless to other people. Encryption technique ensures data integrity and integrity as hackers cannot access your data and use it for malicious activities. Therefore, organizations, individuals, and the government need to apply the necessary encryption techniques to ensure their information safety.
