SECURITY DEVICES AND TOOLS
Which do you think of the security devices or tools are most effective?
Choose at least three (3) and justify your answer if it is for personal use or
for systems security.
a) Firewall and Encryption
Firewall and Encryption when combined are strong for systems
security. A firewall consists of software and hardware set up
between an internal computer network and the Internet to filter out
unwanted access. Encryption is the process of encoding data that
can only be viewed by authorized individuals. Encryption is widely
used in systems like e-commerce and Internet banking.
b) Anti-virus
The anti-virus software helps us protect our devices and files from
viruses. It looks at applications, downloaded data, files, hardware,
and web pages to check if there are any threats and flag suspicious
behaviors. Its function is to block or remove malwares as quickly as
possible. It also confirms if your computer is safe or has been
infiltrated by malwares.
c) Intrusion Prevention System
An intrusion prevention system (IPS) is a system that monitors a
network for malicious activities such as security threats or policy
violations. The main function of an IPS is to identify suspicious
activity, and then log information, attempt to block the activity, and
then finally to report it to the host.
