So let’s get started and examine these fundamental ideas as a group.
Common Cybersecurity Terminology
The term “malware” refers to software that is intended to damage or exploit computer systems. A large category of harmful software known as malware includes viruses, worms, trojan horses, ransomware, and spyware.
Types of malware:
- Computer software known as a virus can multiply and propagate from one machine to another.
- Worm: An autonomous computer software that replicates itself and spreads over a network without user input.
- Trojan: A software that gives the impression of being helpful but is meant to do bad things.
- Malware that encrypts a victim’s files and demands money in return for the decryption key is known as ransomware.
- Spyware is a category of software that discreetly gathers user data and transmits it to a distant server.
In 2017, the WannaCry ransomware assault hit over 200,000 systems in 150 different countries.
Iranian nuclear facilities were attacked by the Stuxnet malware in 2010.
From compromised PCs, the Zeus malware harvests banking passwords and user information.
An example of a social engineering assault is phishing, in which the attacker tries to convince the victim to divulge private data like passwords or credit card details. Phishing assaults are frequently conducted over email or instant messaging, but they can also take place over the phone or through social media.
Types of phishing:
- Spear phishing is a type of targeted phishing assault that is made specifically for one person or group of people.
- Clone phishing is a sort of phishing assault in which an authentic email or webpage is cloned and altered to obtain personal data.
- High-ranking officials or other valuable targets are the focus of a particular kind of phishing assault called whaling.
- Users of Microsoft Office 365 were the subject of a phishing effort in 2020 that used a phony Google reCAPTCHA page to collect their login information.
- Customers of American Express were the subject of a phishing attack in 2019 that used a phony login page to collect their credit card information.
- Employees of the Democratic National Committee were the subject of a spear phishing attempt in 2018 that sought to collect private political data.
A firewall is a piece of network security hardware that monitors all incoming and outgoing network traffic and uses a set of security rules to either allow or disallow it. Networks must be protected from unauthorized access and harmful traffic with the help of firewalls, which can be either hardware- or software-based.
Types of firewalls:
- A firewall that filters traffic based on the source, destination, and ports of network packets is known as a packet-filtering firewall.
- Stateful firewall: A firewall that keeps track of the status of network connections and makes judgments about which packets to allow or block based on that information.
- A firewall operating at the OSI model’s application layer that may base judgments on particular application protocols is known as an “application-layer firewall.”
- A common hardware-based firewall used in business networks is the Cisco ASA firewall.
- Small business and residential networks frequently employ the open-source pfSense firewall software.
- A software-based firewall included with the Windows operating system is the Windows Firewall.
To preserve the secrecy of data, the plaintext is transformed into ciphertext through the process of encryption. Only the correct key or password will unlock the ciphertext. Sensitive data, including financial transactions, private information, and official correspondence, are frequently protected via encryption.
Types of encryption
- A kind of encryption in which the same key is used for both encryption and decryption is known as symmetric-key encryption.
- Asymmetric-key encryption: A form of encryption where the encryption and decryption keys are distinct.
- Data of any size may be converted into a fixed-size output using the hashing technique, which is frequently employed to ensure the accuracy of data.
- A popular symmetric-key encryption technique is called the Advanced Encryption Standard (AES).
- One widely used asymmetric-key encryption method is RSA.
- Data integrity checks often employ the SHA-256 hashing technique.
A vulnerability is a weak point or fault in a system that an attacker may use to obtain access without authorization or carry out malevolent acts. Software, hardware, or even human behavior may be vulnerable. Cybersecurity must include both vulnerability identification and patching.
Types of vulnerability:
- Software flaw: A flaw in software that an attacker may use to compromise the system.
- Hardware flaw: A flaw in the hardware that an attacker may use to undermine the system.
- A vulnerability that occurs as a result of human action, such as giving up passwords or falling for phishing schemes, is known as a social engineering vulnerability.
- The OpenSSL cryptographic software library’s Heartbleed flaw made it possible for hackers to obtain private keys and other sensitive data.
- The CPU flaws Spectre and Meltdown made it possible for hackers to obtain private data from other processes.
- In 2017, a flaw in the Apache Struts web application framework led to the Equifax data leak.
