Cyber Security and It’s Importance
What does cyber security mean?
We should start from the basics and understand Cyber Security and It’s Importance. Cybersecurity is the collection of measures and practices taken to protect computers, networks, programs, or systems from cyberattacks. Such attacks can take the form of malware, denial of service, theft of data, unauthorized access, or tampering of data, and any number of other malicious actions.
“It takes 20 years to build a reputation and few minutes of cyber-incident to ruin it.”
Over the few past years, cybercrimes have increased rapidly with cybercriminals continuously exploring new ways to circumvent security solutions to get illegal access to computer systems and networks.
Cybersecurity deals with protecting anything connected across the network. This includes:
- Hardware like desktops, laptops, servers, and mobiles
- Data in transit and at rest
Some important cyber attacks are as follows:
- Spamming: Spamming is sending unsolicited bulk messages to multiple recipients
- Denial of Service (DoS): A DoS attack makes a system or any other network resource inaccessible to its intended users. It is launched by a large number of distributed hosts
- Phishing: Phishing fraudulently acquires confidential user data by mimicking e-communication, mainly through email and web spoofing Data in transit and at rest
- Malware: Malware is software programmed to perform and propagate malicious activities, e.g., viruses, worms, and Trojans
- Website Threats: Website threats refer to attackers exploiting vulnerabilities in the legitimate websites, infecting them and indirectly attacking visitors of these sites
- zero-day exploit: A zero-day exploit hits after a network vulnerability is announced but before a patch or solution is implemented. Attackers target the disclosed vulnerability during this window of time. Zero-day vulnerability threat detection requires constant awareness.
How to prevent cyber security attacks
- Regularly update antivirus and antispyware software on every computer used.
- Use a firewall for your Internet connection
- Use Strong Passwords
- Keep updating the software’s used
- Backup data regularly
- Encrypt data by using strong encryption techniques .
- Change passwords regularly.
- Do not use public storage for sensitive data.
- Train employees
- Securing your WiFi connections
- Organizations should perform regular phishing simulation and security awareness training program.
