Computers have become crucial in many aspects of our everyday life. It is critical to protect our computers against viruses and other types of malware in order to preserve our data. The phrase "computer security," sometimes known as "cyber security" and "information technology security," refers to the activity of protecting various computer components. The basic purpose of computer security is to prevent and detect breaches.

Computer Security Threats and Vulnerabilities:

Any scenario that jeopardises the integrity of a computer system is considered a danger to computer security. Cyber risks are growing more prevalent as the world becomes more digital. Let's have a look at the vast range of critical issues and weaknesses that afflict today's computer security systems.

  • Viruses 

Simply described, a computer virus is a malicious piece of software that is covertly downloaded and installed on a user's computer. Because this spyware may duplicate itself, any file or application on the system is vulnerable to infection. In the worst-case scenario, these viruses might render the victim's computer completely worthless.

  • Computer Worm

 A computer worm is a harmful application that automatically spreads from one computer to another. Computerworms can totally deplete a system's storage space due to their capacity to proliferate and the rate at which they duplicate. They have the capacity to change or delete data, as well as install further infections. A computer worm can not only propagate itself, but it can also steal data and provide hackers with access to a system

  • Phishing

The perpetrator of "phishing" cybercrime appears as a reputable organisation through email, phone, or text message in an attempt to earn the victim's trust and, as a result, sensitive information such as passwords and financial data.This results in stolen identities and financial damage. Even though people are fully aware of the hazards of phishing, it is surprisingly easy to fall victim to one of these scams.

  • Rootkit

A rootkit is malicious software that may be placed on a computer to hide its actual nature and enable an intruder access to otherwise protected areas. Rootkits allow hackers to make unauthorised modifications to the system and even run programs on the host machine when installed on a computer.

   There will be major issues and concerns that cannot be addressed unless a computer security system is implemented. It is more critical than ever in today's data-driven culture to protect sensitive information and frustrate the attempts of would-be criminals.It is critical to keep a computer clear of viruses and other malware in order to keep sensitive data protected and the computer working properly.

Types of Computer Security:

The hardware, software, network, as well as electronic data in computer systems, can all be protected by employing the following security strategies.

  • Application Security

  • Information Security

  • Network Security

  • Endpoint Security

  • Internet Security

Healthy Computer Security Principles:

With the rising sophistication of cyberattacks, finding effective ways to guard against them is more crucial than ever. Here are a few examples of basic computer security measures that everyone should be aware with in order to avoid the ever-expanding assortment of online threats.

  • Ensure your computer's safety against outside threats: Setup anti-virus software Turn on the firewall.

  • You must stay up with the newest software and upgrades by upgrading your system on a regular basis.

  • In your email, do not open attachments from strangers.

  • Make safe passwords and keep them up to date.

  • Don't pay attention to flashing advertisements or automated downloads.

  • Learn about fundamental computer security precautions as well as the most recent internet threats.

  • It is critical to scan and backup your system on a frequent basis.
