Learn: Security Threats - Why Networks Are Targeted

Welcome!Today we'll explore why networks are targeted by attackers and the types of security threats they face. This lesson will help you understand key concepts and prepare for questions on this topic.

Why Are Networks Targeted?Networks are targeted because they store and transmit valuable data, like personal information, financial data, or business secrets. Attackers aim to steal, manipulate, or damage this data for profit, disruption, or other motives.

Types of Security ThreatsThere are various forms of security threats that attackers use to compromise networks. These include malware, phishing, brute-force attacks, denial of service (DoS), and more. Each has a different method and impact.

Motives for Attacking NetworksAttackers may have different motives, such as financial gain, disrupting services, damaging reputations, or stealing intellectual property. Understanding these motives helps organisations prepare defences.

Forms of AttackLet's look at some common forms of attack:Malware: Software like viruses or ransomware.Phishing: Fraudulent emails or messages asking for sensitive information.DoS (Denial of Service): Overloading a network to disrupt services.

Preventing Security ThreatsOrganisations use various methods to prevent attacks, like firewalls (filtering network traffic), password policies (strong, unique passwords), and anti-malware software (detecting and removing malicious programs).

Review Time!Great work! You've learned about why networks are targeted and the types of security threats they face. Now let's test your understanding with a few final questions.
