- Hacking: When someone tries to break into our accounts or devices
The National Institute of Standards and Technology (NIST) provides a comprehensive guide to these and other cybersecurity threats.
Why Phishing Works
“Phishing was a threat in the cyber world a couple of decades ago and still is today. It has grown and evolved over the years as phishers are getting creative in planning and executing the attacks. Thus, there is a need for a review of the past and current phishing approaches.” – A survey of phishing attacks: Their types, vectors and technical approaches
How Cybersecurity Protects Us
Let’s dive deeper into some specific types of cyberattacks:
- Ransomware: This is a type of malware that locks your files and demands money to unlock them. Learn more about Lockbit Ransomware
- Distributed Denial of Service (DDoS): This attack overwhelms a website with fake traffic, making it crash.
- Man-in-the-Middle (MitM): This is when an attacker secretly relays and possibly alters the communications between two parties.
- SQL Injection: This attack inserts malicious code into a website’s database to steal information.
Cybersecurity uses different tools and techniques to keep us safe:
- Antivirus software: Programs that find and remove viruses
- Firewalls: Digital walls that block unwanted traffic
- Encryption: Scrambling our data so others can’t read it
- Two-factor authentication: Using two ways to prove who we are when logging in
The Cybersecurity Kill Chain
Security experts often talk about the “Cybersecurity Kill Chain.” This is a model that describes the stages of a cyberattack:
- Reconnaissance: The attacker gathers information about the target.
- Weaponization: The attacker creates a weapon, like a virus.
- Delivery: The weapon is sent to the target, perhaps in an email.
- Exploitation: The weapon is triggered.
- Installation: The weapon installs itself on the target’s system.
- Command and Control: The attacker gains control of the target’s system.
- Actions on Objectives: The attacker achieves their goal, like stealing data.
Understanding this process helps cybersecurity professionals defend against attacks at each stage.
Cybersecurity Best Practices for Beginners
