What is Cybersecurity?

Cybersecurity refers to the body of technologies, processes and practices designed to protect networks, devices, programs and data from attack, damage  and/or unauthorized access. Cybersecurity may also be referred to as Information Technology Security.

In this presentation, we are going to discuss cybersecurity at the individual level

Why Cybersecurity?

Phishing

Phishing is a cybercrime in which a target or targets are contacted by email, calls or text message by someone posing as a legitimate institution to lure them into providing sensitive data like banking and credit card details, and passwords.

Examples of Phishing: Credit and Debit Card Fraud

Examples of Phishing: through Emails

Protecting yourself from Phishing

>Be cautious about all communications you receive.
>Do not click on any link listed in the email message without thinking and do not open any attachments contained in a suspicious email.
>Do not enter personal information in any pop – up screens.

Data Breach

A data breach is the intentional or unintentional release of secure or private/confidential information to an untrusted environment.Your leaked data can be used for:
>Identity Theft
>Scamming/Phishing
>Hacking
>Marketing

Actions to take following a breach:

>Check if you have been affected on https://haveibeenpwned.com/ or by contacting the service providers compromised
>Be alert to suspicious messages
>Change your password
>Check your online accounts to confirm there's been no unauthorised activity

Data Breach Example: The recent Facebook Data breach

Social Engineering

Social Engineering is the method of exploiting human psychology, rather than computer vulnerabilities to gain access to systems or data.
        “As humans, we tend to trust details that appear to be from loved ones. Today, many popular online scams start as a spoofed message from someone that you think you know”

Cyberstalking

Cyberstalking is stalking or harassment carried out over the internet. It might target individuals, groups, or even organizations and can take different forms including slander, defamation and threats. Motives may be to control or intimidate the victim or to gather information for use in other crimes, like identity theft or offline stalking.

Malwares

Malware is short for malicious software. It is a blanket term for viruses, worms, trojans and other harmful computer programs used to wreak destruction and gain access to sensitive information. Some malwares also mine cryptocurrency, collect data for selling or make your computer a part of botnet (botnet is like a malicious army of infected devices commanded by hacker(s) who can use it to attack servers or mine cryptocurrency).
Some protection tips for windows users:
>Keep your system updated.
>Install a trusted Antivirus software
>Don't download untrusted files from the internet

Web Browser Exploits

The web browser is one of the most heavily used programs on a computer or mobile device today. Because of its ubiquitous nature, it is also an extremely popular target for attackers.
"In 2021 there have been 176 vulnerabilities in Google Chrome with an average score of 7.9 out of ten. Last year Chrome had 227 security vulnerabilities published."

Protecting web browsers:

>keep your browser updated
>use extensions like ublock-origin and HTTPS Everywhere to prevent XSS, HTTP Downgrade and various other form of attack
>for even more security use Windows Sandboxing or Firejail to sandbox your browser.
>>In computer security, a sandbox is a security mechanism for separating running programs, usually in an effort to mitigate system failures and/or software vulnerabilities from spreading
Cyber-bullying is bullying with the use of digital technologies.. It can take place on social media, messaging platforms, gaming platforms and mobile phones. It is repeated behavior, aimed at scaring, angering or shaming those who are targeted.
If you are being bullied online then you can launch an official complaint against your cyberbully on the National Cyber Crime Reporting Portal.
If you don't want to give out your personal details, you can file a complaint anonymously on this portal too.

Misinformation and Infodemic

Fake news is false or misleading information presented as news. It is now a greater concern than other online security risks like cyber bullying or fraud schemes.

The online poll, which conducted more than 150,000 interviews across 142 countries, found that 57% of internet users believe fake news was the biggest threat, followed by online fraud (45%), and cyberbullying (30%).

Infodemic is a blend of the words "information" and "epidemic" that refers to a rapid and far-reaching spread of both accurate and inaccurate information about something, such as a disease. As facts, rumors, and fears mix and disperse, it becomes difficult to learn essential information about an issue.
