Importance of Data Security
Data security is crucial in today's digital world as it ensures the protection of sensitive information from
unauthorised access, misuse, or breaches. Here’s why data security is important:
Ð ÐSafeguards Personal Privacy: Ensures that sensitive data stays confidential and protected from misuse
or unauthorised access.
Ð ÐProtects Against Identity Theft: Protects personal accounts and financial information from unauthorised
access or misuse.
Ð ÐEncourages Reliability: Helps establish trust and credibility in online transactions and communication
through robust security measures.
Ð ÐPreserves Reputation: Protects individuals and organisations from the harm or embarrassment caused
by leaked personal data.
4.4 SECURITY MEASURES
Security measures are steps taken to protect devices, networks, and data from cyber threats. They aim to
ensure safety, privacy, and reliability in the digital world. Below are some common security measures:
Ð ÐStrong Passwords: A strong password is a combination of at least 8
characters with upper and lower-case letters, numbers, and special
characters that is difficult for unauthorised individuals or automated
programs to guess or crack. It is a very basic step that one should take
and never share the same with even the most trusted ones. Avoid using
birth dates, anniversary dates, and common combinations of numbers.
Some examples of strong passwords are: m#P52s@ap$V, “N4&vQ2! p”.
Ð Ð Control Your Privacy: Customise privacy settings on social media
platforms and online accounts to manage who can access your
personal information and posts. Be mindful of what you share online,
including photos, videos, and personal details, as once shared, they
may be challenging to remove. Taking control of these settings helps
protect your data and maintain your online privacy.
Ð ÐSecure Connections: Always use websites with HTTPS encryption
for safe communication and avoid using open or unsecured Wi-Fi
networks.
Ð Ð Data Backup: Data backup refers to the process of creating copies
of data to ensure that it can be restored in the event of data loss
due to natural disasters, accidents, cyber-attacks, or other unexpected
events. Sometimes physical backup media is used to secure in access-
controlled environments. Another method to secure data can be the
cloud backup which is considered more reliable.
