- "Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system."
The study of techniques used to identify and mitigate vulnerabilities in computer systems and software.
Understanding the basic concepts of vulnerability analysis: This includes understanding the basic concepts and definitions of vulnerability, threats, risks, and exploitation.
Types of vulnerabilities: This includes understanding different types of vulnerabilities, such as application-level vulnerabilities, network-level vulnerabilities, and system-level vulnerabilities.
Identification of vulnerabilities: This includes using tools and techniques to identify vulnerabilities in a system.
Risk assessment: This involves conducting a risk assessment of a system after identifying vulnerabilities.
Exploitation: This includes understanding how hackers exploit vulnerabilities in a system.
Penetration testing: This involves simulating an attack on a system to see how a hacker could exploit vulnerabilities.
Cryptography: This involves understanding the basic concepts of encryption, decryption, digital signatures, and other cryptographic techniques.
Secure coding practices: This includes understanding secure coding practices for writing secure software.
Threat modeling: This involves identifying potential threats to a system and mapping them to potential vulnerabilities.
Security controls: This includes understanding various security controls, such as access controls, authentication, and authorization.
Security testing: This includes using tools and techniques to test the security of a system.
Incident response: This involves understanding how to respond to a security incident.
Compliance: This includes understanding security compliance regulations and standards.
Social engineering: This involves understanding how hackers use social engineering to exploit vulnerabilities in a system.
Data protection: This includes understanding how to protect data confidentiality, integrity, and availability.
Security architecture: This involves understanding how to design and build secure systems.
Security policies and procedures: This includes understanding the importance of security policies and procedures in maintaining a secure system.
Attack mitigation: This involves understanding how to mitigate and counteract attacks on a system.
Vulnerability reporting and management: This includes understanding how to report vulnerabilities and manage them.
Security auditing: This involves assessing a system's security posture to ensure it complies with industry standards and regulations.
Penetration Testing: Involves providing an authorized simulated attack on a computer system, network or application to identify vulnerabilities.
Vulnerability Scanning: Involves using automated tools to discover vulnerabilities in computer systems, networks or applications.
Threat Modeling: Involves identifying potential threats and vulnerabilities to a system, and assessing their potential impact on the system.
Security Auditing: Involves a comprehensive evaluation of the security of a computer system, network or application, including the identification of existing vulnerabilities, threats and risks.
Source Code Review: Involves examining and analyzing software source code to identify vulnerabilities, errors and other security issues.
Fuzz Testing: Involves automated testing that inputs invalid, unexpected, or random data into an application or system to identify vulnerabilities and potential crashes.
Root Cause Analysis: Involves identifying the underlying causes of a security breach or vulnerability to help prevent future incidents.
Physical Security Assessment: Involves a comprehensive evaluation of the physical security controls and measures in place to protect computer systems, networks and data.
Configuration Management Review: Involves a systematic assessment of the configuration settings and controls within a computer system, network or application to ensure secure and optimal configuration.
Risk Assessment: Involves identifying potential risks and threats to a computer system, network or application, and assessing the likelihood and impact of the risks.
- "Vulnerabilities can be weaknesses in either the hardware itself, or the software that runs on the hardware."
- "Vulnerabilities can be exploited by a threat actor, such as an attacker, to cross privilege boundaries within a computer system."
- "To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness."
- "Vulnerability management is a cyclical practice."
- "Discover all assets, prioritize assets, assess or perform a complete vulnerability scan, report on results, remediate vulnerabilities, verify remediation - repeat."
- "Agile vulnerability management refers to preventing attacks by identifying all vulnerabilities as quickly as possible."
- "A security risk is often incorrectly classified as a vulnerability."
- "The risk is the potential of a significant impact resulting from the exploit of a vulnerability."
- "Then there are vulnerabilities without risk: for example, when the affected asset has no value."
- "A vulnerability with one or more known instances of working and fully implemented attacks is classified as an exploitable vulnerability."
- "The window of vulnerability is the time from when the security hole was introduced or manifested in deployed software, to when access was removed, a security fix was available/deployed, or the attacker was disabled—see zero-day attack."
- "Security bug (security defect) is a narrower concept."
- "There are vulnerabilities that are not related to software: hardware, site, personnel vulnerabilities are examples of vulnerabilities that are not software security bugs."
- "Hardware, site, personnel vulnerabilities."
- "Constructs in programming languages that are difficult to use properly can manifest large numbers of vulnerabilities."
- "Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system."
- "Vulnerabilities can be exploited by a threat actor, such as an attacker."
- "Vulnerability management is a cyclical practice that varies in theory but contains common processes which include: discover all assets, prioritize assets, assess or perform a complete vulnerability scan, report on results, remediate vulnerabilities, verify remediation - repeat."
- "Agile vulnerability management refers to preventing attacks by identifying all vulnerabilities as quickly as possible."
