Phishing attacks involve social engineering tactics where attackers trick victims into revealing sensitive information or clicking on malicious links. The sophistication of phishing attacks has increased with the use of AI-generated emails and deep fakes.
Distributed Denial-of-Service (DDoS) Attacks
DDoS attacks overwhelm systems by flooding them with traffic from multiple sources. This can lead to service disruptions and data loss, causing significant financial losses for organizations.
Insider Threats
Insider threats come from employees or trusted individuals who have authorized access to systems. These threats can be particularly damaging as they often go undetected until significant damage has been done.
The Role of Encryption in Protecting Data
Encryption is a fundamental component of cyber security, ensuring that data remains confidential even if it falls into the wrong hands.
How Encryption Works
Encryption involves converting plaintext into ciphertext using algorithms and keys. Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys (public and private).
Real-World Applications
Encryption is used in various applications such as end-to-end encrypted messaging services like WhatsApp and secure transactions on the internet.
Network Security: Defending Against External and Internal Threats
Network security involves protecting systems from both external and internal threats.
Firewalls, IDS/IPS
Firewalls act as barriers between networks, blocking unauthorized access. Intrusion detection systems (IDS) monitor network traffic for signs of unauthorized access or malicious activity. Intrusion prevention systems (IPS) go a step further by actively blocking detected threats.
Securing Wireless Networks
Wireless networks are particularly vulnerable due to their open nature. Securing these networks involves using strong passwords, enabling WPA3 encryption, and implementing guest networks.
Zero-Trust Architectures
Zero-trust architectures assume that all users and devices are potential threats until proven otherwise. This approach ensures that even internal users do not have unfettered access to sensitive data.
