Cybersecurity is the practise of protecting your computer systems, data, networks, mobile devices, and other electronic systems from malicious attacks. It is also known as electronic information security or information technology security. Cybersecurity is used widely by different companies to stay protected from hackers, ransomware attacks, financial losses, and data breaches.
With so much technological advancement, there is still a dark side to it, such as cyber-attacks and other malicious threats that are prevalent in every step of modern technological advancement. This questions all of us about what cybersecurity is and why it is important.
What is cybersecurity?
Cybersecurity acts as a line of defense against cybercrime, such as attacks attempting to breach, access, or damage data, or targets attempting to harm any sensitive or non-sensitive issues of a business organization. Cybersecurity is also responsible for preventing attacks that aim to disable or disrupt a system's or device's operations.
Types of cyber attacks:
There are different types of dangerous cyber attacks organisations can face; some of these are listed here.
DNS poisoning attacks: it is the act of entering false or wrong information in the DNS cache to generate incorrect query responses and lead users to unknown and wrong websites.
Malware attacks: are software designed exclusively to destroy computers and computer systems. Some examples of malware include viruses, worms, spyware, adware, and ransomware.
Backdoors: are a means to access a computer system or encrypted data that bypasses the system's customary security mechanisms.
Crytojacking: Cryptojacking is the illegal use of others' computer resources to mine cryptocurrency. Desktops, servers, cloud infrastructure, and more are all hacked by hackers to illicitly mine for crypto coins.
The latest cyber threats include:
Emotet Malware: The Australian Cyber Security Center warned national organisations in 2019 about a newly discovered threat from Emotet malware.
Dridex Malware: It uses Microsoft Office macros. It helps hackers steal confidential information. It typically appears as a spam email with a Microsoft Word document attached to it.
Why is cybersecurity important?
Cyberattacks are increasing effectively.
Cyber attacks continue to grow at a very rapid pace, with attackers using an ever-expanding variety of tactics. There is an urgent need to use cybersecurity practices to protect your business systems from threats and exploitation.
To maintain the CIA triad:
CIA stands for Confidentiality, Integrity, and Availability. These three are very important factors for any business. Cybersecurity makes it possible to maintain these principles and create a safe and protected environment for your data and information.
Data breaches are a common occurrence we come across in this digital era, in a world full of digitization where we are surrounded by hackers all over the world. Sensitive data has to be kept safely, so cybersecurity automatically becomes crucial for protection.
There are different types of cybersecurity:
Network and perimeter security.
IAM(Identity and access management)
