Cybersecurity is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. Also known as information technology (IT) security, cybersecurity measures are designed to combat threats against network systems and applications, whether those threats originate from inside or outside an organization.
Why is cybersecurity important?
The world is getting on increasingly digital. Here in point, there comes the needs for us to strengthen our cybersecurity to face possible risk and cyber challenges. The goal of cybersecurity is to prevent unauthorized or unattended access, destruction, and changes to data, networks, programs, and other information. Security threats and cyber-attacks have made cybersecurity a significant issue in the modern world.
Categories of Cybercrime.
The list of cybercrime is long and varied, but cybercrime falls into three main categories:
1. Individual: This category includes a variety of cybercrime carried out against a single person.
2. Property: As more business activity continues to move online, stealing data and intellectual property is one of the most profitable and common types of cybercrime.
3. Government: This category of cybercrime often involves state-sponsored attackers and cyberterrorists in targeting another country’s secrets and critical infrastructure.
Types of Cybercrime
Cybercrime continues to grow and evolve, some common Cybercrime are:
1. Phishing: Perhaps the “original” email scam, phishing is when fraudsters spam users online with emails promising prizes or threatening an account suspension. Phishing remains the most popular form of cyber-attack, and it has endured despite all efforts to fight it off. Recently, phishing has evolved in new directions, such as targeted spear phishing, smishing (via text message) or vishing (using voicemail).
2. Identity theft: Just as it sounds, identity theft involves stealing personal information to use for fraudulent purposes. Cybercriminals can attack individuals through phishing scams or break into corporate systems, and steal databases of sensitive information such as credit card or Social Security numbers.
3. Ransomware: Cybercriminals have developed the highly profitable tactic of breaking into databases, extracting and deleting files, or encrypting them so the organisation they belong to can’t get access.
4. Denial of service (DoS): In the traditional DoS version, attackers flood a service or computer network with requests. This overwhelms the website’s servers, causing them to crash and taking the site offline.
5. Malware attacks: Ransomware is one type of malware attack, but malicious software comes in many varieties, all designed to infiltrate a computer system and perform an unscrupulous activity on behalf of a cybercriminal.
How to Protect Against Cybercrime
The types of cybercrime are constantly evolving, so individual and companies must remain alert. Some basic ways to protect against cybercrime are:
· Police your email: Fraudulent emails are at the heart of many types of cybercrime, so individual and organisations need to pay close attention.
· Set up web browsing guardrails
· Update your software regularly.
· Deploy a VPN: Virtual private networks (VPNs) offer a layer of protection, especially when working remotely or in the cloud. These services encrypt data to keep outsiders from spying on web traffic.
· Enforce strong password hygiene
Conclusion
Services such as email protection, business continuity and data back-up, as well as training will enable individual and organisations to maintain operations and recover from attacks.
