In this blog, we are going to have a deeper understanding about quantum computing, how it differs from traditional computing, cybersecurity, threats and ways to secure them. It will give an overview how the quantum computing is impacting cybersecurity.
Understanding quantum computing
Quantum computing is the emerging field of cutting-edge computer science which is based on the principle of quantum mechanics. It performs computations more efficiently than the classical computers. The basic unit of information in quantum computing is qubit or quantum bit. Qubits can be a 0, one or any linear combination of the two. The quantum algorithms are designed in a way which allows a quantum computer to perform the calculation quickly and efficiently.
Quantum computing can be applied into four major categories namely cybersecurity, data analytics and artificial intelligence, optimization and simulation and data management and searching.
There are four key principles of quantum mechanics listed below-
1. Superposition: It is that state in which a quantum particle can represent a combination of multiple possibilities.
2. Entanglement: It is the process in which multiple quantum particles become correlated strongly than the regular ones.
3. Decoherence: It is the process in which the quantum particles can collapse, decay or change by converting into single states measurable by classical physics.
4. Interference: It is the phenomena in which the quantum states can interact with each other and produce most likely probabilities.
With enough capacity, an ideal quantum computer can break the inscription standards we use today. By finding prime factors of a large and teaser in just minutes instead of the thousands of years it would take for a classical computer to do.
Technologies are advancing faster than ever. The cell phones we have today are more powerful than the mainframes that we used to send people to the moon. The researchers believe that we will soon be entering into an era of quantum advantage where quantum computers will be used to accelerate classical computers just like GPUs.
Classical computing vs Quantum Computing
1. Classical computing is used by large scale multipurpose devices. Whereas, quantum computing is used by high speed quantum mechanics based computers.
2. Information is stored in bits in classical computing. On the contrary, quantum computing uses quantum bits to store its information.
3. In case of classical computing, same input will give same output upon repetition. Whereas, there is multiple possible output for the same input.
4. Classical computing code the processing of data is carried out by logic and in sequential order you don’t look contrary, in quantum computing the processing of data is carried out by quantum logic and at parallel instances.
Understanding Cybersecurity
Cybersecurity based universe during the production of computer software, networks and systems from threats which can lead to the unauthorised disclosure of information.
In the contemporary world, cybersecurity is emerging as a most significant challenge good due to the complexity of information system and the society they support, it is emerging as a challenge to the society various smart devices including smartphones, televisions and other devices comprising of Internet of Things it’s being created nowadays. It has become quite crucial for the system which governs large scale system to look into the matter of security.
There are many aspects of computer security including digital security such as electronic password and inscription, physical security such as metal lock in order to prevent unauthorized tampering.
Types of Cybersecurity
- Network security
- Information security
- Application security
- Cloud security
- Internet of Things security
- Mobile security
Need of Cybersecurity
Cybersecurity is important across different sectors such as government organizations, startups, mid and large enterprises and even for personal use. Gone are the days of simple firewalls and antivirus software being our sole security measures. Cybersecurity risk is increasing and without its help, the organization cannot defend itself against data breach campaigns. With the increase in the rate of cybercrime, cybersecurity has gained a huge importance in the society. Therefore, the security of information is quite vital for the functionality of the organization. It also ensures the safe operation of the application. the information is needed to be confidential to protect the data collected by the organization.
Threats
- Data threat: It occurs when the attacker uses a system without the consent of the owner to gain private information such as login credentials. Data threat is similar to data theft.
- Insider threat: It occurs by the employee of an organization. The employee might misuse his or her login credential to penetrate into the network to gain confidential data from the organization system.
- Malware attack: It is the insertion of malicious code into the device.
- Password attack: Password attack is unethically entering into the system by trying to guess or crack the password.
- Botnets: It is a network of interconnected devices running on board. It is a software application program for a particular task. This network is controlled by an attacker.
- Phishing attack: It is a type of social engineering attack in which the attacker dupes the victim by sending a fake e-mail or text message. When the victim clicks on the malicious link, the system freezes and the sensitive information is revealed.
- Ransomware: It is a malware when downloaded, it deletes the data in the computer.
- Security misconfiguration
- Injection attacks
- Cross site scripting
- Sensitive data exposure
Ways to secure
- Encryption: It is the process of converting data into code. The encrypted data can be decrypted only by authenticated user. The original data is called as plain text and descriptive data is called as Cipher text.
- VPN: VPN stands for virtual private network. It is a secured private network for sending data into a network via internet connection. It hides the IP address of the user and then redirects when it takes to the server where the VPN host handles it.
- Multifactor authentication: It is the authentication of user at multiple steps. Most of the social media sites have two factor authentication facility. If the user has activated 2 factor authentication, when he or she logs in into an account from a new device, he or she needs to undergo the two-factor authentication each time period it can be done in multiple steps.
- Create unique and strong passwords.
- Delete inactive accounts.
- Update your application frequently.
- conduct application security audit.
- Keep backup of important data.
