Introduction to Cybersecurity and the Concept of “Attack”

To best protect your organisation’s digital assets, it’s important to understand what constitutes a cyber attack. A cyber attack is any attempt to expose, alter, disable, destroy, steal, or gain unauthorised access to or make unauthorised use of an asset. Within the scope of information security, these attacks are not just disruptive but can be catastrophic, making it imperative for those in charge of organisational security, like Chief Information Security Officers (CISOs) and IT managers, to have a comprehensive grasp of these threats.

Evolution of Cyber Attacks with Technology

As technology has advanced, so have the methods and sophistication of cyber attacks. Traditional forms of malware have evolved into more complex ransomware and phishing schemes, while network attacks have grown to include Distributed Denial of Service (DDoS) and Man-in-the-Middle (MitM) attacks. The continuous evolution of these threats necessitates a dynamic and informed approach to cybersecurity.

Origins of Cyber Attacks in the Digital Landscape

Cyber attacks can originate from various sources in the digital landscape, including state-sponsored groups, criminal organisations, hacktivists, and even disgruntled insiders. The motivations behind these attacks vary, encompassing financial gain, political agendas, espionage, and the desire to disrupt services. Understanding the origin and intent of these threats is necessary for developing targeted defence strategies.

Common Types of Cyber Attacks Explained

Understanding the various forms of cyber attacks is essential for maintaining robust cybersecurity. This section delves into the characteristics and mechanisms of prevalent cyber threats.

Malware and Ransomware Attacks

Malware encompasses malicious software designed to damage or disrupt systems. It can take the form of viruses, worms, trojans, and more. Ransomware is a type of malware that encrypts a victim’s files, demanding payment for the decryption key.

Phishing and Social Engineering

Phishing attacks deceive individuals into providing sensitive information by masquerading as trustworthy entities. Social engineering extends beyond digital means, manipulating individuals into breaking security protocols.

SQL Injections and DDoS Attacks

An SQL injection is a technique that exploits vulnerabilities in a database-driven application to execute malicious SQL statements. Distributed Denial of Service (DDoS) attacks overwhelm systems with traffic, rendering them inoperable.

Man-in-the-Middle (MitM) and Advanced Persistent Threats (APTs)

MitM attacks intercept and potentially alter communications between two parties without their knowledge. APTs involve prolonged and targeted cyberattacks, often state-sponsored, aiming to steal information over extended periods.
