If you are a student pursuing computer science and engineering as a course, then hold on; you need to read this blog till the end.
Have you ever found yourself struggling to gather online study material, Cyber security, or topic/questions you need to prepare for your cyber security semester exam?
Worry not. We have enlisted the most frequently asked basic questions in semester examinations.
Let’s get started with it.
What is Cyber Security?
Defending systems, networks, and programs from online threats is known as cybersecurity. The typical objectives of these cyberattacks include gaining access to, altering, or destroying sensitive data, demanding money from users, or interfering with regular corporate operations.
Since there are more devices than humans and attackers are getting more creative, implementing effective cybersecurity protocols is quite tricky today.
Introduction to Cyber Security
For a business to have a successful defense against cyberattacks, the people, processes, and technology must all work in unison. Multiple layers of security are dispersed across the computers, networks, programmes, or data that one wants to keep secure in an effective cybersecurity strategy. Users must be aware of and adhere to fundamental data security rules like using strong passwords, being cautious when opening email attachments, and regularly backing up their files.
Technology is crucial in providing businesses and individuals with the computer security tools they need to defend themselves against cyberattacks. Endpoint devices including PCs, smart devices, routers, networks, and the cloud are the three key things that need to be secured. Next-generation firewalls, DNS filtering, malware protection, antivirus software, and email security solutions are some of the technologies frequently employed to safeguard these institutions.
Types of Cyber Security threats?
- The most typical kind of cyber attack is this one. Phishing is the act of sending phony emails that look like they are coming from reliable sources. The intention is to steal private information, including login credentials and credit card numbers. You can protect yourself from phishing through education or a technological solution that filters harmful emails.
- Malicious software comes in the form of ransomware. It is made to extort money by preventing the use of the computer system or files until the ransom is paid. Paying the ransom does not ensure that the system will be fixed or that the files will be returned.
- Malware refers to malicious software that cybercriminals or hackers have developed to disrupt or harm a genuine user’s computer. It is one of the most prevalent cyber crimes. Malware is frequently distributed through an unauthorized email attachment or a download that appears legitimate. Cybercriminals can use it to steal money or launch cyberattacks with political motivations.
- Adversaries may employ social engineering to deceive you into disclosing sensitive information. They can ask for money or try to access your private information. Any abovementioned risks can be paired with social engineering to increase your propensity to click on links, download malware, or believe a suspicious source.
- SQL (structured language query) injection takes over and steals data from a database. Cybercriminals use malicious SQL statements to install malicious malware into databases by taking advantage of flaws in data-driven applications. They now have access to the delicate data stored in the database.
- Cybercriminals use denial-of-service attacks to prevent computers from responding to valid requests by flooding networks and servers with traffic. This makes the system useless and prevents an organization from performing essential tasks.
- “Man-in-the-middle” (MitM) include an attacker intercepting and relaying messages between two parties that they believe are communicating with one another.
Importance of Cyber Security?
In the interlinked world today, cutting-edge cyber defense programs benefit everyone. A cybersecurity assault can personally lead to anything from identity theft to extortion attempts to the loss of crucial information like family photos. Critical infrastructure, such as power plants, hospitals, and financial service providers, is necessary for everyone. To keep our society running smoothly, securing these and other institutions is crucial.
Everyone gains from the efforts of cyber threat researchers who look into new and existing risks and cyber assault tactics, such as the 250-person threat research team at Talos. They strengthen open source tools, expose new flaws, and inform others about the value of cybersecurity. Their efforts increase everyone’s online safety.
Challenges of Cyber Security?
Hackers, data loss, privacy concerns, risk management, and evolving cybersecurity tactics present ongoing cybersecurity threats. In the foreseeable future, it is not anticipated that the number of cyberattacks will decline. Additionally, the emergence of the internet of things (IoT) has added attack access points, necessitating a greater network and device security requirement.
The fact that security dangers are constantly changing is one of the most challenging aspects of cybersecurity. New attack vectors are created due to the emergence of new technologies and their use in a novel or unconventional ways. It might be challenging to keep up with these constant changes and advancements in assaults and to update procedures to defend against them. Concerns include ensuring that all cybersecurity components are regularly updated to guard against any vulnerabilities.
Cyber security is the defense against cyber threats to systems connected to the internet, including their hardware, software, and data. Individuals and businesses both deploy this technique to prevent illegal access to data centres and other digital systems.
A solid cybersecurity plan can offer a good security framework against malicious assaults intended to gain access to, alter, delete, destroy, or extort sensitive data and systems belonging to a business or user. Security measures are essential in preventing attacks that take down or impair a system or device’s functionality.
End-user education should be a part of cybersecurity measures, as staff members may unintentionally introduce malware onto the premises on their laptops or mobile devices. Employees who regularly receive security awareness training can help protect their firm from cyber threats.
