What is Cybersecurity?

Cybersecurity is the practice of securing networks, devices, and data against unauthorised access or illegal usage, as well as the art of maintaining information confidentiality, integrity, and availability. Communication (e.g., email, cellphones, tablets), entertainment (e.g., interactive video games, social media, apps), transportation (e.g., navigation systems), shopping (e.g., online shopping, credit cards), medicine (e.g., medical equipment, medical records), and the list goes on. How much of your daily life is influenced by technology? How much of your personal information is stored on your own computer, smartphone, tablet, or on the system of another person?

What are the dangers of weak cybersecurity?

There are numerous dangers, some of which are more dangerous than others. Malware deleting your entire system, an attacker breaking into your system and modifying files, an attacker using your computer to target others, or an attacker taking your credit card information and making unauthorised transactions are all examples of these threats. Even with the best protection, there is no guarantee that any of these things will not happen to you, but there are steps you can do to reduce your risk.

What steps can you take to strengthen your cybersecurity?

Recognizing the risks is the first step in protecting yourself. To better comprehend the hazards, become acquainted with the following terms:

Hacker, attacker, or intruder — These phrases refer to individuals who aim to exploit flaws in software and computer systems for personal gain. Although their goals are occasionally benevolent and motivated by curiosity, their actions are frequently in conflict with the intended usage of the systems they are exploiting. The outcomes can range from harmless mischief (developing a virus with no malicious intent) to malicious conduct (stealing or altering information).

Malicious code - Malicious code (also known as malware) is a set of unwanted files or programmes that can harm a computer or compromise data stored on it. Malicious code is classified into several types, including viruses, worms, and Trojan horses. (For further details, see Protecting Against Malicious Code.) Malicious code may exhibit the following traits:

• It may be necessary for you to take action before it infects your machine. This activity could be as simple as opening an email attachment or visiting a specific website.
• Some types of malware spread without the interaction of the user and often begin by exploiting a software weakness. After infecting the victim's computer, the malware will attempt to find and infect other machines. Malware can also spread through email, websites, or network-based software.
• Some virus pretends to be one thing while actually doing something else behind the scenes. An application that claims to speed up your computer, for example, may actually be sending personal information to a remote attacker.

Vulnerabilities are defects in software, firmware, or hardware that an attacker can exploit to perform illegal actions in a system. They can be caused by programming flaws in software. Attackers use these errors to infect systems with malware or engage in other harmful activities.

Follow these fundamental cybersecurity recommended practices to reduce the risks of cyberattacks:

• Maintain software updates. Install software patches to prevent attackers from exploiting known flaws or vulnerabilities. Automatic updates are available in many operating systems. You should enable this option if it is accessible.
• Use the most recent antivirus programme. A trustworthy antivirus software application is a crucial safeguard against known dangerous threats. It can identify, quarantine, and remove numerous types of malware automatically. To provide optimal protection against the most recent threats, allow automatic virus definition updates. Because detection relies on signatures—known patterns that can identify code as malware—even the greatest antivirus will not guard against new and advanced threats like zero-day vulnerabilities and polymorphic viruses.
• Make use of strong passwords. Choose passwords that are difficult to guess for attackers, and use separate passwords for different programmes and devices. It is preferable to use long, strong passwords or passphrases with at least 16 characters.
• Modify the default usernames and passwords. Malicious actors have easy access to default usernames and passwords. Change default passwords to a sufficiently strong and unique password as soon as possible.
• Set up multi-factor authentication (MFA). Authentication is the process of validating a user's identity. Attackers frequently take advantage of inadequate authentication processes. MFA authenticates a user's identity using at least two identification components, reducing the danger of a cyber attacker getting access to an account if they know the username and password.
• Set up a firewall. Firewalls may be able to prevent some sorts of attack vectors by preventing unwanted traffic from entering a computer system and limiting needless outbound communications. A firewall is included in some device operating systems. Enable and configure the firewall according to the device or system owner's documentation.
• Be aware of unexpected emails. Phishing emails are now one of the most common threats to the regular user. A phishing email's objective is to obtain personal information about you, steal money from you, or install malware on your device. Be wary of any unexpected emails.
