COMPUTER SECURITY

Our lives have been positively changed by the internet in various ways. Unfortunately, the expansion of security concerns has also been a side effect of this massive network and the technologies it is connected to. Being knowledgeable about accepted cybersecurity procedures is the best method to defend oneself against these risks and attacks.

Computer security, cybersecurity, or information technology security (IT security) is the defence of computer systems and networks against malicious actors who may attack them in order to reveal confidential information, steal or damage hardware, software, or data, or disrupt or reroute the services they offer.


                                                            TYPES

1.Cybersecurity

Protecting our computers, electronic devices, networks, software, and systems from cyberattacks is known as cyber security. assaults that take place while our machine is connected to the Internet are referred to as cyber assaults.

2. Information Security

Information security refers to safeguarding our system's data from theft, unauthorised use, and illegal use. Confidentiality, information integrity, and accessibility are the main goals of information security.

3. Application Security

Ensuring that our applications and data are protected from hacking and that the databases of those applications stay secure and private to the owner only ensures that user information is kept private.

4. Network Security

Network security is the process of securing a network and safeguarding the data of users.

THREATS

1.Viruses

 A malicious programme that is secretly installed on a user's computer is known as a computer virus. It multiplies and contaminates the user's PC's programmes and files. The main objective of a virus is to prevent the victim's computer from ever functioning correctly.

 2. Computer worm

 A computer worm is a piece of software that can autonomously copy itself from one computer to another. Due to a worm's ability to replicate in large quantities and quickly, there is a chance that this will consume all available hard disc space on your computer.

 3. Phishing

 Phishers seek to steal important financial or personal information through phoney email or instant chats by posing as a reliable person or company. Unfortunately, it's incredibly simple to commit phishing. You may enter your personal information since you are led to believe that it is the real mail.

 4. Rootkit

 A rootkit is a type of computer programme that actively conceals its existence while continuing to grant privileged access to a machine. Once a rootkit has been installed, its controller will have access to the host machine's system configurations and the ability to remotely execute files.

 

 FUTURE SCOPE

Today, more than ever, we conduct both our personal and professional lives online, making computer security a crucial concern. Knowing what computer security's future holds will help you use your resources wisely and be safe not only today but also tomorrow. Because of the industry's ongoing evolution in reaction to the changing tactics used by cybercriminals and the fresh threats they create, the future of computer security is difficult to foresee. For instance, the rise in global ransomware hacks (opens in new tab) between 2018 and 2019 led cybersecurity experts and companies to design new tools to buck the trend.

CONCLUSION

Security dangers cannot be eliminated, but you can be aware of them and remain vigilant. To secure people's data and information, many cyber security standards have been developed. These standards also offer some procedures via which people can seek redress if they have been subjected to any kind of cyber security threat.

As cybercrime and computer security risks rise, new defences against them are constantly needed. There is always a need for new techniques to counteract these security problems. It's critical to comprehend how to detect dangerous software on your computer and how to handle it.

Unhackable Internet

  W hy it matters?   The internet is increasingly vulnerable to hacking; a quantum one would be unhackable. Quantum Computing    A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a the quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss.   Now, Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards a practical quantum internet and a major step forward in the development of long-distance quantum networks.   The U.S Department of Energy (DoE) explains how a quantum link will make it happen through two quantum phenomenon: the first is quantum entanglement, where two-particle ...

Impact of Social Media on Business

Watch out for that bird! Imagine you are skydiving, you are visiting one of the most beautiful countries in the world and you want to share that experience with your loved ones and friends. Why not send a postcard? Oh wait, you’re already back from the trip by the time that postcard has reached, or it got lost in the mail. If only there was an alternative. This isn’t 1990. You have a platter of platforms to share your adventure. Webster’s dictionary defines social media as-“ forms of electronic communication (such as websites for social networking and microblogging) through which users create online communities to share information, ideas, personal messages, and other content (such as videos).”In simple words, social media, are various public platforms where people can share their views, stories, etc. with the help of various mediums. Starting with websites such as MySpace, Orkut, and Facebook, etc. it is now estimated that there are about 200 social media websites in ...

Pegasus Spyware: Flying Through The Air

 Hundreds of millions of people can't imagine life without their smartphones. Almost every aspect of their daily lives, from the most mundane to the most intimate, is within easy reach and hearing distance of their smartphones. Only few people realize that their phones may be used as surveillance devices, with someone hundreds of miles away secretly extracting their messages, photographs, and location while also activating their microphone and recording them in real time. Such capabilities are present in Pegasus, a spyware produced by NSO Group, an Israeli maker of mass surveillance weapons. What is Pegasus? Pegasus is a hacking software – or spyware – that is developed, marketed and licensed to governments around the world by the Israeli company NSO Group. It has the capability to infect billions of phones using either iOS or Android operating systems. The spyware is named after Pegasus, the white winged horse from Greek mythology. It is named so because it "flies through the...
