What is Cybersecurity? Cybersecurity is the protection applied to computer systems, devices and networks, to prevent cyberattacks of any kind that may be designed to access or destroy your sensitive data. Cybersecurity protects businesses and private persons from financial as well as personal live damages.
What are cyber attacks?
Cyberattacks include hardware and software damage, and electronic data theft. They can also cause service disruption. They continue to evolve with technology and increasing expertise. It is not only a threat to businesses but also individuals. An attack can access data, which may be destroyed, stolen, or used for blackmail. Businesses can completely lose income, while individuals may have their identities stolen.
Cyber crime is on the rise
The average cost of cybercrime for organisations have increased from USD 1.4 million -> USD 13.0 million and from 2019 to 2023, approx USD 5.4 trillion in global value will be at risk because of cyber attacks.
What is the best defense against cyber attacks?
To protect a single computer or a network, a capable cybersecurity system is required. Multiple layers of protection may be needed. Protection here is a combination of the right technology and wise cyber defence options by computer users. You need to understand what should be the right defence for your particular computer system. You may need the help of a cybersecurity specialist for some advice, or you can just continue reading this guide.
What is Cybersecurity is one question but what are the differences between Cybersecurity, computer security, and IT security?
The three terms are all interconnected. The first one, cyber security, has already been defined at the beginning. You need it to protect your devices, computers, systems, networks, and even the minutest data. You are basically shielding whatever you have from cybercriminals.
But how do you exactly achieve this type of security?
This is where all three terms come in. They are the main components of cyber security. You need an infrastructure that is divided among the three.
- Information technology (IT) security protects data not only when it gets transferred via a network. It also protects the physical data and its storage location. You can then say that IT security prevents both cybercriminal activity and physical intrusion.
- Cyber security is similar to IT security because it protects digital data or data moving through a network. It does this by ensuring that unauthorized access for whatever reason (destruction, stealing, extortion, etc.) will not get through. It does not deal with physical data. It is merely a subset of IT security.
- Network security is also called computer security. This is a subset of cyber security. It protects data being passed between computers in the same network. through the help of software and hardware. It shields the IT infrastructure from cybercriminals.
Types of Cyber Security
Security can even be further broken down into several types. You need to know each of these to see if you have enough tools to guard your data.
- Application security: This uses software and hardware to bounce external threats. You more likely have an antivirus program installed and a firewall set. Encryption is also a type of application security.
- Cloud Security: This software based tool monitors even the data that you have sent to the cloud. This helps prevent any cloud attacks.
- Critical Infrastructure Security: This is made up of cyber-physical systems. The term “infrastructure” is key here. Water purification systems and the electricity grid of your city are examples of such infrastructures.
- Data Loss Prevention: It is the application of recovery plans if in case a cyber security breach aimed at destroying or stealing data occurs. Network and data storage permissions are part of this.
- End-user education: Phishing victims would not have clicked that dubious link if they had gone through end-user education. Devices should start including a short manual for best practices online.
- Information Security: It protects any type of data from malicious attacks of varying reasons.
- Network Security: This protects internal networks through stronger passwords, 2-factor authentication, and other moves to secure infrastructure.
What are the different types of cyber-attacks?
These are attacks on:
- Availability: This is an attack on individuals to block them from their own data. They need to pay the cyber criminal(s) holding their data ransom. Some criminals even know which businesses to infiltrate. These are the ones that will lose everything if the data gets revealed.
- Confidentiality: This is an attack that can cost you all your money or your whole identity. Cyber criminals get hold of your personal information, including but not limited to credit card details. After your information has been stolen, it may be sold to others through the dark web, or may even be used by the attacker himself.
- Integrity: These are often referred to as leaks. They are aimed to expose an organization’s or a person’s supposed wrongdoings. This act is sabotage is meant to make people mistrust or even hate the target. Even innocent data can be twisted for this black propaganda.
If you want a more specific list of cyber threats, here are some:
- Advanced Persistent Threats (APTs) – This is an attack on integrity. The cyber attacker infiltrates networks that are likely to contain a lot of sensitive information. He may stay there for a time, undetected and not really doing anything destructive, except for stealing data. Big finance, manufacturing companies, and even national defense are the likely targets of APTs.
- Malware – This attack on availability is short for malicious software. It is specially created to access and destroy data from your computer. You may get it from one simple download, but it can wreak so much havoc: login information theft, spam-sending spree, installed spyware, viruses, computer crashes, and more. Conduct your research before downloading that free new application.
- Ransomware – This is an attack on availability that aims to encrypt your data so that you cannot access it. The victim must pay a ransom to get hold of his own files again. These attacks include lockers, crypto malware, and scareware.
- Social Engineering – This attack on confidentiality tricks people into giving away their information through seemingly trustworthy means. Phishing is a good example of this. These cyber attackers know what exactly an email recipient or ad clicker wants to read or hear to take the next step.
What are the different categories of cyber security threats?
Cyber security threats evolve all the time. At this point, though, these are the threats that you have to be aware of. Don’t think that you will not fall victim to any of them even if you feel like you are an ordinary person who does not own a company or have millions.
- Cyberattacks may be done for the sake of politics. They may be aimed to get hold of sensitive information that may be used to taint a possibly influential person’s reputation.
- Cybercrime can be committed by one person or a whole group who are aiming for your system to steal lucrative data and even to just make quite a mess.
- Cyberterrorism is aimed at breaching supposedly strong electronic systems to create fear in the targeted community or company.
How do you protect yourself from cyber attacks?
- Do not open email attachments. They can be riddled with malware.
- Do not click on strange links.
- If you are not sure the email is from someone you know or a site that you have business with, ask the person or call customer service.
- Be wary of the complete URL. This means you have to look for https://. These are secured sites. Avoid entering sensitive data on a page with an http:// in the URL.
- Update your devices frequently because software updates include new security features. You have to update to bounce off fresh versions of cyber attacks.
- Back up your files (hardware, software, cloud) to avoid getting completely wiped out by an attack. Make sure each storage is secure.
Now, you know that you have to be always on your toes when it comes to cyber security. Cyber security continues to evolve, as your antivirus and firewalls are advertising. Yes, they are right. They are offering more features each time because cyber attacks are also evolving. There is no need to panic when you go online. You just need to practice caution. You can start with the right software and hardware.
By the way – Did you ever try the TOR browser?
