In this blog, you will learn about the Disciplines and Goals of Cyber Security. I covered all the essential topics related to that and gave some tool names so that we can achieve all disciplines of Cybersecurity. So let’s get started with the blog.
Introduction
Before learning about the Disciplines of cybersecurity, we must know what cybersecurity really is. Cybersecurity protects computer systems, networks, programs, and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves implementing measures and technologies to prevent and mitigate potential threats and vulnerabilities in the digital realm.
Disciplines of CyberSecurity
Disciplines of cybersecurity address various aspects of protection, including:
A) Information Gathering
Information gathering, also known as reconnaissance or footprinting, is an essential phase in cybersecurity. It involves collecting relevant data and intelligence about a target system, network, or organization.
This information is valuable for understanding the potential vulnerabilities and attack surface, enabling security professionals to take proactive measures to protect against potential threats.
However, it’s important to note that information gathering should only be performed within legal and ethical boundaries.
Some important information-gathering tools are Nmap, Nikto, and Unicornscan.
B) Vulnerability Analysis
Vulnerability analysis, also known as vulnerability assessment or vulnerability scanning, is a critical process in cybersecurity that focuses on identifying and evaluating vulnerabilities in computer systems, networks, applications, and infrastructure.
It involves systematically scanning and analyzing the target environment to discover potential weaknesses that could be exploited by attackers.
It identifies the threats and assesses their risk to protect systems and data from unauthorized access.
Some important Vulnerability Analysis tools are DotDotPwn, Lynis, Sfuzz, and OpenVAS.
C) Web Application Security
Web application security is a crucial aspect of cybersecurity that focuses on protecting web applications from various threats and vulnerabilities.
Web applications, such as online banking portals, e-commerce platforms, and social media sites, are commonly targeted by attackers due to their accessibility and potential for financial gain or data theft.
It protects the website and online services against different security threats that exploit vulnerabilities in an application’s code.
Some important Web Application Security tools are Blind Elephant, Dirbuster, Burpsuite, and WPScan.
D) Password Attacks
Password attacks are techniques used by attackers to gain unauthorized access to user accounts by exploiting weaknesses in passwords.
These attacks aim to guess, crack, or bypass passwords to compromise user accounts, gain unauthorized privileges, potentially access sensitive information, or perform malicious activities.
Passwords are the primary form of authentication and have also been subjected to various forms of attack over the years.
Some important Password Attack tools are BruteSpray, CeWL, John the Ripper, and HashCat.
E) Wireless Attacks
Wireless attacks refer to security threats and techniques aimed at exploiting vulnerabilities in wireless networks, such as Wi-Fi, Bluetooth, or cellular networks.
These attacks can compromise the confidentiality, integrity, or availability of wireless communications and the devices connected to them.
It can shut down the wireless network, steal information flowing through the network, and result in identity theft.
Some important Password attack tools are Aircrack-NG, Kismet, and Crackle.
F) Reverse Engineering
Reverse engineering is the process of analyzing a technology, system, or piece of software to understand its design, functionality, and behavior.
It involves deconstructing and examining the components, structure, and algorithms of a product to gain insights into its inner workings.
Kali Linux comes equipped with reverse engineering tools that help you tear down applications and services to their bare bones, revealing vital information about them.
Some important Password attack tools are apktool, dex2jar, OllyDbG, and JDGUI.
G) Exploitation Tools
Exploitation refers to the act of taking advantage of vulnerabilities or weaknesses in computer systems, networks, or software to gain unauthorized access or control or perform malicious activities.
Exploitation is typically performed by malicious actors or hackers with the intent to compromise the security and integrity of the targeted system.
Some important exploit tools are Metasploit, BeEF, RouterSploit, and Netcat.
H) Sniffing and Spoofing
Sniffing and spoofing are two techniques used in cybersecurity, but it’s important to note that they can be used for both legitimate and malicious purposes.
Sniffing, also known as network sniffing or packet sniffing, is the process of capturing and analyzing network traffic.
It involves intercepting and examining packets of data that are transmitted over a network. Sniffing can be done using specialized software tools or hardware devices, such as network analyzers or packet sniffers.
Spoofing involves the manipulation or falsification of network or system parameters to deceive or impersonate legitimate users, systems, or devices.
Some important Sniffing and Spoofing Tools are Hexinject, Wireshark, Burpsuite, and BetterCap.
I) Forensic Tools
Forensics in cybersecurity refers to the practice of collecting, analyzing, and preserving digital evidence related to security incidents, cybercrimes, or other malicious activities.
Cybersecurity forensics plays a crucial role in investigating and understanding the nature of cyber incidents, identifying the perpetrators, and aiding in legal proceedings.
Some important Forensic Tools are Bulk extractors, Dumpzilla, Volatility, and Maltego.
J) Maintaining Access
Maintaining access, also known as persistent access or maintaining persistence, is a technique used by attackers in cybersecurity to maintain unauthorized access to a compromised system or network over an extended period of time.
It allows attackers to continue their malicious activities, gather sensitive information, or launch further attacks without being detected or losing access.
In simple words, it is the process of maintaining a connection with the already-hacked system to access it later.
After the attacker has set up a backdoor for the target, various tools are used to maintain this backdoor so that a payload can be executed.
Some important Forensic Tools are Nishang, Weevely, Powersploit, and Cryptcat.
K) Hardware Hacking
Hardware hacking in cybersecurity involves manipulating or exploiting the physical components of a computer system or electronic device to gain unauthorized access, extract sensitive information, modify functionality, or perform other malicious activities.
It is a specialized field that focuses on the vulnerabilities and weaknesses present in hardware devices.
Some important Hardware Hacking Tools are Arduino, the Android SDK, and Smali.
L) Stress Testing
Stress testing, also known as load testing or performance testing, is a cybersecurity practice that involves evaluating the resilience and stability of a system or application under various demanding conditions.
The goal is to assess how well the system can handle high loads, excessive traffic, or resource-intensive activities, and to identify any performance bottlenecks or vulnerabilities.
Stress Testing exposes software systems to simulated cyberattacks, revealing potential weaknesses and vulnerabilities in their implementation, which can then be corrected prior to deployment and lead to improved software quality.
Some important Stress tests are Funkload, MDK3, and Reaver.
M) Reporting Tools
In cybersecurity, reporting tools play a crucial role in collecting, analyzing, and presenting information related to security events, incidents, vulnerabilities, and overall system or network health.
These tools provide insights into the security posture of an organization, aid in compliance requirements, and facilitate decision-making processes.
Some important Stress tests are Dradis, MagicTree, and Metagoofil.
Goals of CyberSecurity
The three primary goals of cybersecurity are often referred to as the CIA triad, which stands for Confidentiality, Integrity, and Availability.
These goals outline the fundamental objectives that organizations strive to achieve in order to protect their information systems and data from unauthorized access, modification, or disruption. Here’s a brief overview of each goal:
