Cyber Security is the practice of protecting systems, networks, devices, applications, or any other digital infrastructure against malicious attacks. The purpose of these attacks is to access, manipulate, destroy sensitive data or extort money from unsuspecting victims.
In today’s digital age, cybercrime affects all of us directly or indirectly because as individuals and companies, we all have information that is worth something to cybercriminals. We are living in an increasingly digital world and it is very important that we educate ourselves about cybersecurity.
As cybercrime is getting bigger every day and the perpetrators are getting more sophisticated, we are all vulnerable and the responsibility is on us as individuals, companies, and organizations to strengthen our defenses and reduce the risks by educating ourselves about cybersecurity. Cybersecurity starts with all of us and it is our greatest weapon and best defense against any cyber attack.
Examples of common cyber attacks:
1. Ransomware attack: This is a situation whereby a victim’s device, system, or network is held hostage until the victim pays a ransom to the attacker.
2. Distributed Denial of Service (DDoS)This happens when a system, service, or network is flooded with excessive traffic so as to prevent them from working properly.
3. Social engineering: e.g. phishing attack. This is when an attacker sends an email that appears to be coming from a trusted individual or organisation.
4. Malware attack: This happens when hackers use applications to compromise devices or networks in order to steal personal or sensitive information.
5. Insider Threat: This is when the people in an organisation have access to a system, device, or network and use it to gain access to restricted areas for malicious purposes.
6. URL manipulation: This happens when an attacker creates a fake URL address or changes it in order to gain access to the sensitive information of an unsuspecting individual or organisation.
7. Eavesdropping attack: This refers to the stealing of information as it is transmitted over a smartphone, computer, network, or other connected devices.
Examples of common cybersecurity measures:
1. Use a strong password: Let your password be at least 12 characters. Mix uppercase letters, lower case letters, numbers, and special characters.
2. Don’t use the same password on different accounts or websites.
3. Use Two-factor of Multi-factor Authentication.
4. Don’t allow automatic connectivity settings to remain active.
5. Avoid clicking on strange and suspicious links.
6. Always use antivirus and firewalls.
7. Update systems and programs regularly.
8. Always sign out of your online account when you are through with your online activities.
9. Avoid connecting your devices to public Wi-fi.
10. Don’t shop on unsecured websites. Watch for “HTTPS“.
11. Don’t allow suspicious people to have access to your devices.
12. Switch off your Bluetooth when you are not using it.
13. Don’t download attachments from unknown sources.
14. Beware of unsolicited calls, emails, or text messages that request personal information.
15. Educate yourself, your family, and staff about cybersecurity.
Why is cybersecurity awareness important in today’s digital age?
1. It will reduce the vulnerabilities of individuals, companies, and organizations.
2. It will allow employees to work safely and reduce their errors.
3. It will ensure maximum protection of sensitive information belonging to individuals and corporate organizations.
4. It will reduce the number of victims of cyber attacks who may attempt suicide if they lose money or sensitive information through security breaches.
5. It will improve clients’ confidence and business continuity.
6. It will reduce social engineering attacks e.g. phishing which is very rampant in today’s digital age.
7. It will increase productivity because virus infections can reduce the speed of computers.
8. It will ensure maximum protection against ransomware attacks which may ruin companies or government organizations within a short time.
9. Personal information, industries, and government information systems will be more protected from manipulation, damage or theft.
10. In today’s technology age, the prevalence of Internet of Things (IoT)devices has increased the number of hackers and cybercriminals. However, cybersecurity awareness is the only weapon against the attackers.
