Cyber security

Cyber security is the technique of preventing harmful threats on computers, servers, mobile devices, electronic systems, networks, and data. It’s also known as electronic information security or information technology security. Cyber security is the use of technology, processes, and policies to prevent cyber assaults on systems, networks, programmes, devices, and data. Its goal is to limit the risk of cyber assaults and secure systems, networks, and technology from unauthorized use.

Network security refers to the process of protecting a computer network from intruders, such as targeted attackers or opportunistic malware.

  • Application security is concerned with ensuring that software and devices are free of dangers. A hacked application could allow access to the data it was supposed to secure.
  • Security starts throughout the design phase, long before a programme or device is deployed.
  • Data integrity and privacy are protected by information security, both in storage and in transit.
  • End-user education addresses the most unpredictably unpredictable aspect in cyber-security: people. By failing to follow appropriate security measures, anyone can unintentionally introduce a virus into an otherwise protected system. It is critical for every organization’s security to teach users to delete suspicious email attachments, not plug in unrecognized USB drives, and various other vital teachings.

The scale of the cyber threat

The worldwide cyber threat is rapidly evolving, with an increasing number of data breaches each year. According to a survey published by Risk Based Security, data breaches exposed 7.9 billion records in the first nine months of 2019. This is more than double (112%) the number of records disclosed at the same time last year.

Most breaches occurred in medical services, retail, and government entities, with malicious criminals being accountable for most occurrences. Because they collect financial and medical data, some of these industries are particularly appealing to cybercriminals. Still, any organization that uses networks might be targeted for customer data, corporate espionage, or customer attacks.

The International Data Corporation projects that global spending on cyber-security solutions will reach a whopping $133.7 billion by 2022, as the scope of the cyber threat continues to grow. Governments worldwide have issued recommendations to help businesses implement effective cyber-security policies in response to the growing cyber threat.

The National Institute of Standards and Technology (NIST) in the United States has developed a cyber-security framework. The framework promotes constant, real-time monitoring of all electronic resources to combat the spread of harmful malware and aid in early identification.

Types of cyber threats

Cyber-security counters three types of threats:

  1. Cybercrime refers to individuals or groups who attack systems for monetary gain or to cause disruption.
  2. Politically motivated information collection is standard in cyber-attacks.
  3. The goal of cyberterrorism is to generate panic or dread by undermining electronic systems.

So, how do criminals obtain access to computer systems? Here are some of the most typical ways that cyber-security is compromised:

Malware

Malware is a term that refers to malicious software. Malware is software designed by a cybercriminal or hacker to disrupt or damage a legitimate user’s computer. It is one of the most common cyber dangers. Malware, commonly sent by an unsolicited email attachment or a legitimate-looking download, can be used by cybercriminals to gain money or politically motivated cyber-attacks.

There are different sorts of malware which includes the following:

  • Virus: A self-replicating programme that infects files with malicious code after attaching itself to a clean file and spreading throughout a computer system.
  • Trojans: Is a form of malware that masquerades as genuine software. Users are duped into downloading Trojans onto their computers, which then inflict damage or collect data.
  • Spyware: A programme that secretly records what a user performs for hackers to profit from it. Spyware, for example, could record credit card information.
  • Ransomware: Malware encrypts a user’s files and data and threatens to delete it unless a ransom is paid.
  • Adware: Advertising software that has the potential to propagate malware.
  • Botnets: Malware-infected computer networks that cyber criminals employ to conduct tasks online without the user’s consent.

SQL injection

An SQL (structured language query) injection is a cyber-attack that allows a hacker to take control of a database and steal information from it. Cybercriminals exploit vulnerabilities in data-driven systems by using a malicious SQL statement to install malicious code into a database. This gives them access to sensitive information in the database.

Phishing

Phishing is a type of cybercrime in which cybercriminals send victims emails that look to be from a reputable company and ask for personal information. Phishing attacks are frequently used to trick people into giving over personal information such as credit card numbers.

Man-in-the-middle attack

A man-in-the-middle attack is a type of cyber threat in which a hacker intercepts a conversation between two people to obtain information. On an insecure WiFi network, for example, an attacker could intercept data passing between the victim’s network and the internet.

Denial-of-service attack

A denial-of-service attack occurs when thieves flood a computer system’s networks and servers with traffic, preventing it from fulfilling legitimate requests. This makes the system unworkable, prohibiting an organization from doing essential tasks.

Essential Cyber Security Strategies

Create a security system: Unlike typical administrative systems, which handle operations and rule enforcement from the top down, a security system based on your human resources must be established from the bottom up. This enterprise security system begins with safeguarding the devices that your employees utilize in the workplace. Work on developing an accountability culture so that everyone can communicate when processes don’t seem to be working as they should.

Increase your employee skillset: Your cyber security is only as good as the weakest link in the chain. Train your employees on the most recent IT best practices regularly. Help them understand that their efforts are vital to safeguarding company assets. It is in their best interests to expand their IT knowledge base, whether they are software developers or marketing specialists. Paying for code boot camps for your staff is a significant investment, even if it is initially costly.

Backup your data: You must back up your organization’s data regularly, much as the top You Tuber’s do with the video footage they record. Always back up your data, files, and any other electronic material that is critical to your organization, as well as the latest drafts/iterations of projects your team is working on.

Put the cloud to work: Although the cloud has its disadvantages, storing data in the cloud reduces the risk of losing vital information. Medium and small organizations can save money by storing data on the cloud. Cloud storage and cloud security tools may scale with the business when small firms rise and flourish due to increased sales. Cloud storage and cyber security choices are continuously developing, ensuring that your company always has the most up-to-date solutions.

Invest in your IT infrastructure: Install anti-virus and firewall software on your machines. Firewalls will deter the average cybercriminal from causing harm to your business. Update your computer security systems regularly. When it comes to investing in your IT infrastructure, don’t be hesitant.

The Future of Cyber Security

Cybercrime is increasing at an alarming rate. A high-profile cybercrime is recorded almost every week. Every company is at a different stage of digital transformation; but, no matter how far along your company has progressed, security should remain the top priority, as it has always been and will continue to be.

Information Technology Dependence

Cyber security and information technology are inextricably linked, which means that future cyber security is closely linked to the growth of cyberspace and future information technology. Nearly all significant systems are interconnected and controlled by computers in the current generation, and this trend is projected to continue.

Extensive data and complexity in systems

Future cyber security systems should deal with vast amounts of data, a more significant population and make real-time judgments. It’s complicated, and it could have implications for future cyber security. Unlike in the physical world, where we can identify our adversaries and know the particular weapons they employ, in cyberspace, anyone can become our adversary and attack us at any time.

Cyber security and mitigation

There is a greater need to detect and track threats to plan for mitigation or prevention ahead of time. This includes determining how a project or organization will act in a cyber threat or risk and potential mitigation measures.

 A firm’s or organizations most valuable assets, as well as its weaknesses, must be identified.

There will be a need to adopt more artificial intelligence due to a scarcity of specialists that can cope with security challenges.

The Internet of Things

As more organizations use technology like the internet, cyber-attacks are increasing in both complexity and number. Security experts are well-versed in protecting our mobile devices and computers, but what about our home automation devices, such as refrigerators, vehicles, thermostats, and other appliances, as well as medical equipment?

Numerous cyber risks present substantial challenges to IT professionals in many industries. This means a pressing need to develop new technologies that can cope with big data analytics, cognitive computing, and the Internet of Things to affect our linked environment better. Solutions should be the focus of initiatives. Users of new and evolving technologies should use strong passwords and avoid opening unsolicited or questionable emails, as well as untrustworthy attachments and links
