What is the Purpose of Cyber Security? 

The purpose of cyber security is to protect systems, networks, and data from online threats and unauthorised access. It ensures that sensitive information stays safe and accessible only to authorised users, preventing potential harm. When thinking about what is the purpose of cyber security, it becomes clear that it also helps maintain trust by keeping data reliable and secure. Cyber security reduces risks by blocking attacks such as malware, ransomware, and phishing. By safeguarding important data and ensuring smooth operations, it plays an essential role for both individuals and businesses. 

• Preventing Unauthorised Access

Cyber security ensures that only authorised people can access systems and data, keeping them protected from hackers and unauthorised users. It prevents outsiders from entering networks or stealing valuable information by using tools like strong passwords, firewalls, and multi-factor authentication. These measures add extra layers of security, making it harder for attackers to break in. What is the purpose of cyber security in this context? It ensures that access is given only to trusted individuals, reducing the chances of insider threats and accidental data leaks. By carefully controlling access, businesses and individuals can keep their information safe, secure, and reliable, preventing disruptions and ensuring smooth operations.

• Protecting Sensitive Information 

One of the main goals of cyber security is to protect sensitive information, such as personal details, financial records, and business data. It makes sure hackers cannot access or misuse this information for things like identity theft or fraud. Cyber security uses tools like encryption, which turns data into unreadable code, and data masking, which hides important details. This keeps data safe when stored and shared. Protecting sensitive information helps individuals keep their personal data secure and allows organisations to maintain trust and avoid financial losses. It also ensures privacy is protected by keeping data safe from unauthorised access.

• Ensuring Data Integrity and Availability 

Cyber security helps ensure that data stays correct and available whenever needed. It stops unauthorised users from changing, deleting, or damaging important information. Regular backups save copies of data so it can be restored if lost or attacked. Monitoring systems check for unusual activity to keep data accurate and safe. Disaster recovery systems make sure that, even after a cyberattack, information stays accessible without major delays. This helps individuals and organisations avoid disruptions, keeping everything running smoothly and their data reliable.

• Safeguarding Against CyberAttacks

Cyber security helps protect against different types of attacks, like malware, ransomware, and phishing. These attacks can harm systems, lock files, or steal important information. Using antivirus software, firewalls, and training people can help stop these attacks. Staying careful and taking simple safety steps reduces the risk of these threats. This helps individuals and organisations keep their systems safe and running without problems.

Types of Cyber Threats

Cyber threats come in different types, and knowing them helps individuals and organisations stay safe from online risks. These threats are harmful actions that aim to steal data, disrupt systems, or damage networks. Common examples include malware, phishing, and ransomware, each posing unique risks. Understanding what is the purpose of cyber threats reveals that attackers exploit weaknesses for personal gain or to cause disruption. Being aware of these threats makes it easier to take simple steps like using strong passwords, keeping software updated, and staying alert online to stay protected.

Below are the types of cyber threats:

• Malware 

Malware is harmful software designed to enter systems without permission and damage data, applications, or operating systems. It can cause serious problems, disrupt operations, steal information, and take a lot of effort to fix. A common type of malware is spyware, which tracks personal activities and can be used for financial fraud. Malware is often connected to phishing, where hackers trick people into sharing sensitive information that allows malware to enter their systems. Preventing malware requires scanning email attachments, limiting admin access, avoiding unsafe files, and regularly updating systems with security patches.

• Ransomware 

Ransomware is a type of malware that locks users out of their systems or data until a ransom is paid, often using virtual currencies like Bitcoin. It is a common tactic used by cyber criminals to demand money in exchange for access. Ransomware encrypts files on a network, and the attacker keeps the key needed to unlock them. They then demand payment to release the key, holding the data hostage. Detecting these attacks early is difficult because hackers constantly develop new techniques. Organisations should train employees and implement strong security controls to stay safe. Additionally, developing business continuity and incident response plans can help reduce the impact of an attack.

• Spam and Phishing

Spam refers to unwanted or unsolicited emails and messages sent to users. Phishing is a harmful type of spam that tricks people into sharing sensitive information. Cyber criminals pretend to be trusted individuals or organisations, often using official-looking emails with familiar logos and names. These emails usually ask the recipient to click a link or provide personal details. The link leads to a fake website, where any information entered goes straight to the attackers. Staying cautious with unexpected messages and avoiding suspicious links can help prevent spam and phishing attacks.

• Corporate Account Takeover (CATO)

Corporate Account Takeover (CATO) is a type of cyber theft where criminals pretend to be a business and send unauthorised wire transfers or ACH payments. The stolen money is moved into accounts controlled by the criminals. Businesses with weak security or poor control over online banking are more at risk of these attacks. CATO can cause serious financial losses. Cyber criminals often use malware to carry out these attacks by tricking people through emails, fake websites, or disguised software. Keeping systems secure and regularly checking online banking activities can help prevent CATO.

• Distributed Denial of Service (DDoS)

A Distributed Denial of Service (DDoS) attack floods an online service with excessive traffic from multiple sources, making it unavailable to users. This surge in traffic slows down the website’s response time and blocks access. Cybercriminals create large networks of infected computers, known as Botnets, by spreading malware across devices. DDoS attacks are often used as a distraction, giving hackers a chance to carry out other intrusions or fraud unnoticed. While the service struggles with the fake traffic, attackers may try to steal data or cause further harm.
