With handheld devices becoming more and more
ubiquitous each day and networking having its roots so deeply embedded in our
lives, the world around us is becoming more and more cyber and technologically
advanced with each passing day and it’s hard to avoid the threats it entails.
attackers range from sophisticated hackers to naive teenagers using cyber
vulnerabilities to their advantage. One such threat reported as of May 2017,
when the world witnessed one of the worst cyber outcries, Wanna Cry Ransomware,
a malicious malware that affected thousands of companies in over 150 countries.
Britain’s Nation Health Service was worst hit by the attack and it also brought
many of Spain’s top companies to a halt. This malicious malware first targeted
computers functioning on obsolete versions of Microsoft Operating System and
then infected other systems on the network. The attack lasted 4 days bringing
about an extensive damage of hundred billion dollars.
Numerous businesses and institutions now function
solely on technology and share sensitive data and effectuate transactions over
networking. This advancement makes cyber security indispensable and calls for a
robust and standardized solution to remedy technological vulnerabilities that
can compromise one’s identity and privacy and at times cost livelihood.
Enlisted are some of the most effective measures to protect your computer and
keep your data intact:
· Strong Passwords:
Implementing complex and various alpha-numeric combinations for a password can
prevent an attack or an unwanted encroachment of your devices to an extent.
· Data back-up:
Performing regular back-up for your data is a key feature of data security. In
case our security systems get compromised causing loss of data, we still have
access to our data.
· Implementing control access and updating
systems and installing Intrusion Detectors: Restricting
data and service access to limited authorized personal and controlling physical
approach to the premise can help keep threats at bay. Also keeping critical data offline and its
limited sharing is crucial. Timely updating our security systems can help us
stay one step ahead of the attackers. Intrusion Detectors helps monitor network
traffic and alerts and issues warning on detecting any suspicious activity.
· Installing Firewalls, Antivirus
filters the incoming and outgoing data on a network and block malicious content
from infecting your systems. Also prevents navigating unsecure websites and
potentially threatening content from being downloaded to your computers.
Antivirus programs, on the other hand monitors your systems for any unusual
behavior, traces and destructs any dangerous software or viruses.
· Data Encryption: Encryption
adds an extra wall of security to sensitive information stored on a system or a
network. It employs a systematic algorithm to encrypt data to a code formally
called ciphertext which can only be
read if one has the permitted key or password to access that data , restricting
data interpretation and manipulation.
Insurance: Small or large scale business projects
shall issue a cybercrime insurance that can cover for their losses in case of a
OTP (One Time Password): Various business institutions can enforce OTP’s to ensure
secure financial transactions with customers. OTP’s are generated by employing
various algorithms and they have a limited validity of one
transaction/session. OTP’s are more secure than statics passwords as they are
not vulnerable to encroachment or accidental revelation.
· CAPTCHA (Completely Automated Public
Turing Test to tell Computers and Humans Apart): Hackers can employ various web applications
or design specific algorithms to make spurious entries or hoax registrations to
create a passage to upload malicious content on your systems or network. CAPTHA
is a real-time test that calls for an immediate response to a random distorted
piece of information that can only be interpreted by humans, thus differentiating
bots and humans.
