Everyone Requires Cyber Safety
Definition of Cyber Safety
Cybersecurity is the process of preventing harmful cyberattacks on internet-connected systems such computers, servers, mobile devices, electronic systems, digital networks, and data.
In other words, cyber security is the process of protecting electronic systems, networks, computers, servers, mobile devices, and data from harmful attacks. It is often referred to as electronic information security or information technology security.
Categories of Cyber Safety
Cyber security can be broadly categorized into the following categories:
Network Security: This section focuses on safeguarding an organization's resources and infrastructure from theft, unlawful access, and other harm. Firewalls, intrusion detection systems, Unified Threat Management (UTM), and virtual private networks (VPNs) are among the security measures it entails.
Application Security: This area focuses on protecting databases, web services, and software applications from internet threats. It involves steps like authentication mechanism, authorization, secure coding techniques, and data encryption for sensitive information.
Endpoint Security: The phrase "endpoint security" refers to a number of security methods that guard against viruses, illegal access, and data theft on computers and other devices. Businesses must have efficient endpoint security solutions because cybercriminals constantly develop new ways to exploit endpoint system weaknesses. This section focuses on protecting the devices used by employees, such as laptops, smartphones, and other network endpoints. It consists of measures like disc encryption, firewalls, and antivirus software. Antivirus software and endpoint security are not the same. Endpoint security typically consists of a combination of various security methods, Antivirus is just one of its components. Malicious material can be found and eliminated from a machine using antivirus software.
Cloud Security: This category focuses on protecting data and resources kept in the cloud. It consists of safeguards including multifactor authentication, sharing of permissions, encryption, access limits, and recurring security assessments.
Data Security: This category deals with protecting sensitive data, such as personal information, financial data, and intellectual property, from unauthorized access and theft. It includes measures such as data encryption, data backup and recovery, and data loss prevention (DLP) systems.
Identity and Access Management (IAM): In this category, sensitive data and resources are managed in terms of who has access to them and how. It consists of measures like user management, authentication, and authorisation.
Disaster Recovery and Business Continuity: This category is concerned with making sure an organisation can keep running in the case of a disaster, whether a cyberattack or a natural disaster. It consists of actions like redundancy, disaster recovery planning, and data backup and recovery.
Operational security covers the procedures and strategies used to manage and safeguard data assets. This includes the policies that regulate how and where data may be stored or exchanged, as well as the permissions people have when accessing a network.
The Necessity of Cyber Safety in the Digital Age
Cybersecurity is a must in the digital age. Millions of people's personal information may be exposed because of a single security breach. These violations have a negative financial impact on the businesses as well as a loss of customer confidence. Therefore, it is crucial to have cyber security to shield both individuals and businesses from spammers and internet criminals.
By 2025, cybercrime will cost the world $10.5 trillion annually, according to Cybercrime Magazine. In addition, during the following four years, costs associated with cybercrime are expected to increase globally by about 15% annually. Further, Pandemics, cryptocurrency, and the rise in remote working are all combining to create a target-rich environment for criminals to exploit.
Dark Web is a term for a secretive area of the Internet. This is generally not very comforting. On this Dark web, there are many threats, including illegal arms trade, human trafficking, and other criminal activity. Additionally, on this terrible dark web, hackers may be hired, which has made it much simpler to steal many kinds of personal information. As a result, the public is at danger for their data security. In light of all these elements, the importance of maintaining strong cyber security, computer security, or other device security grows every day.
Furthermore, the problem of a security threat grows increasingly common because average people don't know a lot about security.
Cybercrimes are receiving increased attention from governments all around the world. An excellent example is GDPR. The strictest privacy and security law in the world is the EU's General Data Protection Regulation (GDPR). The 1995 data protection directive's guiding principles have been amended and modernised by this law. It was approved in 2016 and went into effect on May 25, 2018.
Brief History of Cyber Safety
When researcher Bob Thomas developed a computer program called Creeper that could traverse throughout the ARPANET network in the 1970s, the practise of checking for cybersecurity was born. The creator of email, Ray Tomlinson, created the program Reaper, which tracked for and eliminated Creepers. As it created the first computer worms and trojans, Reaper was the very first example of checking a malware antivirus software and the first self-replicating program, i.e., Viruses.
The rise in computer viruses in the 1980s prompted the creation of antivirus software to defend against these dangers. As the Internet expanded in the 1990s, new security risks including malware, phishing, and hacking emerged. Governments all around the world started creating laws and regulations to combat cybercrime in reaction to these dangers.
Here is a timeline of significant events in the history of cyber security:
1989: The first computer worm ever discovered was released, seriously harming numerous computer systems.
1991: The creation of the World Wide Web sparked the expansion of the Internet and the emergence of new cybersecurity threats like phishing and hacking.
1994: In the US, the first law that made computer hacking illegal was approved.
1999: Through email, the Melissa virus spread swiftly and seriously harmed computer systems.
2000s: Better cyber security measures are required in view of the rise of the Internet-related cyberattacks and data breaches.
2002: The Department of Homeland Security was founded by the U.S. government to combat dangers to national security, especially those posed by the internet.
2007: When the first iPhone was released, mobile devices entered the mainstream and the demand for mobile device security increased.
2010s: The development of new security methods to defend against attacks to connected devices was prompted by the advent of the Internet of Things (IoT), which increased the complexity of the cyber security environment.
2013: In order to help enterprises strengthen their cyber security, the National Institute of Standards and Technology (NIST) developed the first version of its Cybersecurity Framework.
2015: Millions of U.S. government workers were impacted by the Office of Personnel Management (OPM) data breach, highlighting the value of data security and privacy.
2018: In the European Union, the General Data Protection Regulation (GDPR) was put into effect, offering stricter safeguards for personal data and stiffer penalties for data breaches.
2020: Due to a sharp rise in remote work brought on by the COVID-19 epidemic, businesses were forced to strengthen their cybersecurity defences.
These are only a few of the significant occasions in the development of cyber security. The necessity for cyber security will remain a crucial concern as technology develops further.
Recent data indicates that cybersecurity will become more widespread. Using cutting-edge technologies like artificial intelligence (AI), blockchain, and machine learning, cybercriminals are experts at conducting stealth stock hacks (ML).
Types of Cyber Threats
Virus and Malware
A virus is a piece of code that attaches to different files and applications, allowing them to become infected and disrupt or corrupt a device whereas, Malware is software that aims to gain unauthorised access to a computer system, usually for the profit of a third party. A computer attacked by a virus can be identified if:
Processing speed slows down.
There will be way too many pop-up windows.
Passwords are changed.
Various programs start to run independently.
When malware software infects your computer, it may:
Attempt to locate personal data
stealing information like payment or stored card details
Start bitcoin mining
Overpower its existence and carry out unwanted activities
Malware can infect a computer in several methods, such as through email attachments, Internet downloads, or by taking advantage of software weaknesses. Malware can affect a computer by stealing confidential data, encrypting files, and requesting payment to decrypt them, or changing how the system functions.
Phishing Attacks
Cyberattacks of the phishing variety aim to obtain sensitive data, including login credentials, credit card numbers, and other personal data.
Typically, these assaults are conducted by sending an email or text message that looks to be from a reliable source, such a bank or a well-known corporation. A link or other instructions, such as login information, may be included in the message. The information is given by the recipient, which the attacker subsequently intercepts.
Phishing attacks can also take the shape of bogus websites that resemble real ones in order to obtain users' personal information. Attacks of this nature are frequently referred to as "cloned" or "spoofed" websites.
When receiving emails or texts asking for personal information, it's crucial to exercise caution, especially if they come from an unreliable source or seem urgent or pressured. It's advised to avoid clicking on links in emails or messages from unknown senders, use two-factor authentication wherever it's practical, and be mindful of frequent phishing attack warning signals like typos or grammatical errors.
Man-in-the-Middle Attacks
The attacker positions themselves between the two parties in an MITM attack, intercepting and potentially altering the communication as it passes through.
For example, a user may attempt to access their online banking account, but the attacker intercepts the communication and redirects the user to a fake website that appears to be the real. The attacker can then steal the user's login credentials as well as any other information provided by the user on the fake website.
MITM attacks can be executed in a variety of methods, such as by utilising rogue Wi-Fi networks, taking advantage of software weaknesses, or utilising specialised hardware like a wireless sniffer.
When sending sensitive information over the Internet, it is crucial to employ secure communication techniques like SSL/TLS encryption to guard against MITM attacks.
Additionally, it's crucial to use only trustworthy networks whenever possible and to exercise caution when connecting to open Wi-Fi networks.
Ransomware Attacks
Ransomware attacks are a type of cyber attack in which an attacker infects a computer system with malware that encrypts and renders the victim's files inaccessible. The attacker then demands a ransom payment in exchange for a decryption key, which will allow the victim to access their encrypted files once again.
Ransomware attacks can be launched in a variety of ways, including via email attachments, Internet downloads, or by exploiting software vulnerabilities. Once installed on the victim's system, the malware will typically spread to other systems on the network, encrypting files and rendering them inaccessible.
Ransomware attackers frequently demand payment in cryptocurrencies like Bitcoin since they are hard to track down.
Additionally, if the ransom is not paid by the specified time, they might threaten to permanently erase the encrypted contents.
Denial-of-Service (DoS) Attacks
A cyberattack known as a denial-of-service (DoS) attempt seeks to prevent the intended users from accessing a computer system, website, or network resource. The attacker does this by flooding the system that is being attacked with a lot of traffic, effectively stopping it from operating normally.
During a DoS attack, the attacker uses a botnet, or network of infected computers or devices, to send many requests to the targeted system. The system is unavailable because of the enormous level of traffic that effectively prevents legitimate users from using it.
DoS attacks are classified into several types, including flooding attacks, which send a large volume of data to the target system, and amplification attacks, which use a vulnerability in a third-party system to generate a large volume of traffic directed at the target.
DoS attacks can cause significant disruption, resulting in lost productivity, decreased revenue, and reputational harm to an organisation. To prevent or mitigate the impact of a DoS attack, organisations can implement security measures such as firewalls, intrusion detection and prevention systems, and traffic filtering.
Cyberterrorism
The use of technology, such as the Internet and computer systems, to commit terrorist activities is known as cyberterrorism. Along with the actual use of technology to harm people, this can also encompass the dissemination of propaganda, the acquisition of private information, and the planning of violent attacks.
For instance, a cyberterrorist organisation could deploy a denial-of-service (DoS) attack to knock down a government organization's website. The attack might entail flooding the agency's servers with a lot of traffic, blocking public access to the website. This kind of attack would aim to make a political statement as well as widespread disruption and panic.
The deployment of malware into vital infrastructure systems, such water treatment facilities or power grids, could serve as another illustration of cyberterrorism. Malware has the capacity to interrupt infrastructure operations and wreak extensive damage, endangering the lives and safety of a sizable population.
Trojans
A type of malware called a Trojan, commonly referred to as a Trojan horse, manipulates a trustworthy application or file to carry out harmful operations on a computer system. The legendary Trojan horse from Greek mythology, which was utilised to conquer the city of Troy by concealing men within a huge wooden horse, is how Trojans got their name.
A harmful application that copies a security utility, like an antivirus program, and is downloaded by the victim as a result of an online fraud or phishing attack is an example of a Trojan. Once it is installed, the Trojan can carry out illicit activities including stealing passwords and other private data or utilising the victim's machine to join a botnet.
Botnets
A botnet is a collection of infected systems that are used in coordinated operations including distributed denial-of-service (DDoS) attacks, spamming, and other malicious activities. A computer that has been infected and hijacked by a malicious attacker is referred to as a "bot," which derives from the word "robot."
A botnet could include infecting Internet of Things (IoT) gadgets with malware, including home routers, security cameras, and smart home gadgets. Through the usage of the software, the malicious actor is able to remotely manage the devices and employ them for coordinated acts like DDoS attacks and spam distribution.
Adware
Adware is a category of computer or mobile software that shows advertising. The ads are typically shown as pop-up windows, banners, or other internet advertising formats.
Adware can be installed on a computer or mobile device without the user's knowledge or agreement because it is frequently packed with other software.
Adware's objective is to persuade people to interact with adverts by clicking or otherwise. When customers click on the internet advertisements that their adware serves, the developers and distributors of adware are paid.
Adware can be legitimate when people agree to it, although it is frequently undesirable. Although adware is frequently merely an annoyance, it can also harbour dangerous risks.
For example, a user can unintentionally download a free software installation and install adware along with it. After that, while the user is using the computer or visiting the web, the adware shows pop-up ads or banners. The user may be targeted with relevant advertisements based on the ads, which may be tied to the user's search history, location, or other personal information.
SQL Injection
A online security flaw known as SQL injection (SQLi) enables an attacker to tamper with database queries that an application makes. In most cases, it enables an attacker to view data that they would not typically be able to access.
Other users' data or any other data that the application itself has access to may fall under this category. In many instances, an attacker can update or remove this data, permanently altering the application's behaviour or content.
Think about a website, for example, where customers can look for things by typing a term into a search box. The website utilises a SQL query to access the necessary data from its database and show the user the outcomes. An attacker might modify the query and be able to retrieve private data from the database by inserting malicious SQL commands into the search box.
Attacks using SQL Injection might have negative effects on users and the website or web application. Validating all user input and correctly sanitising any input that is utilised in a SQL query are essential steps in preventing SQL Injection attacks. SQL Injection risk can be be decreased by employing prepared statements, stored procedures, and parameterized queries.
Best Practices for Cyber Security
Strong and Unique Passwords
One of the most crucial actions you can take to safeguard your online accounts and safeguard your personal information is to create strong and unique passwords. Here are some ideas for developing secure and distinctive passwords:
Length: Make sure your passwords are 12 characters or more in length. The strength of a password increases with length.
Complexity: Use a mix of capital and lowercase letters, digits, and special characters to increase complexity. Avoid using information that could be easily guessed, such as your name, date of birth, or everyday words.
Uniqueness: Don't use the same password for different accounts. The attacker will have access to all of your accounts if only one password is stolen. Refrain from predictable patterns: Avoid using sequential symbols like "12345" or "abcde" Consider utilising a password manager to create and save secure, one-of-a-kind passwords for all of your accounts. Change your passwords frequently: Even if your password has been compromised, frequently changing your passwords can help prevent unauthorised access.
Regular Software Updates
To safeguard your computer against new or current security vulnerabilities, always update your software to the most recent version (particularly OS and Security).
Use of Antivirus Software
It is impossible to have complete and absolute protection from malware if you are connected to the internet. However, by making sure your PCs are equipped with an anti-virus and at least one anti-malware programme, you may dramatically lower your vulnerability.
Two-factor Authentication
You can now setup 2-factor authentication on a lot of platforms to make your accounts secure and safer. It's an additional degree of security that helps confirm that you are the one accessing your account and not an unauthorised person. When possible, turn on this security feature.
Regular Data Backups
A security breach can lead to the loss of crucial data. Your important data should be routinely backed up on the cloud or a local storage device so that you are ready to restore it if it is lost.
Awareness of Phishing Scams
It's important to be attentive and cautious while receiving emails or going to websites that ask for personal information to prevent falling for phishing schemes.
Verifying the sender's email address, being cautious of unusual emails or requests, and avoiding clicking on links or downloading attachments from unknown or dubious sources are some prevention strategies for phishing scams. Individuals and organisations can better defend themselves against phishing schemes by maintaining awareness and knowledge.
The most common way that phishing scams are carried out is through emails or fake websites that pretend to be from a reputable source, such a bank or a well-known corporation. The attacker will request private information that they can use for identity theft or other nefarious activities, such as login passwords or personal data.
Use of Virtual Private Network (VPN)
Between a user's device and the internet, a Virtual Private Network (VPN) technology offers a safe, encrypted connection. Users can shield their online activity and private data from internet risks like hacking, spying, and data theft by using a VPN. All internet communication between the user's device and the VPN server is encrypted with a VPN, making it difficult for anyone to spy or steal private data. Due of this, VPNs are a useful tool for increasing cyber security, particularly while using public Wi-Fi networks or gaining access to private information online.
Additionally, VPNs can assist users in getting around geo-restrictions and internet censorship, enabling them to access websites and online services that may be blocked in their region.
Other good practices include, turn off Bluetooth when not necessary, do not utilise public networks, make some investment on security enhancements, use HTTPS on your website and also try to keep hardware up to date because the most latest software security updates could not work on outdated computer hardware.
