"Computer security, cyber security, digital security or information technology security (IT security) is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide."
A set of techniques used to protect against unauthorized access, theft, or damage of computer systems and networks.
Information Security: This includes the practices and technologies used to secure sensitive information and data from unauthorized access, use, disclosure, disruption, modification or destruction.
Threat Intelligence: This involves the identification, analysis, and prediction of potential security threats to systems and networks.
Network Security: Involves securing computer networks and internet-connected systems against unauthorized access, misuse and modification.
Cryptography: This is the use of mathematical algorithms to secure communication and protect data integrity, confidentiality and authenticity.
Risk Management: This involves identifying, assessing and prioritizing potential security risks to systems and networks.
Cyber Crime Investigation: This involves investigating cyber crime incidents and gathering the evidence needed to prosecute perpetrators.
Cyber Law: This involves the legal issues relating to cyber crime, data protection and privacy, and intellectual property rights.
Disaster Recovery and Business Continuity Planning: This involves planning and implementing measures to ensure the continued availability of critical systems and data in the event of a disaster or major system failure.
Malware Analysis and Reverse Engineering: This involves the analysis of malicious software code to determine its purpose, functionality and potential impact.
Digital Forensics: This involves the recovery and analysis of digital evidence, including data stored on computers, mobile devices and other electronic media.
Social Engineering: This involves manipulating people to gain access to sensitive information or systems by using psychological techniques.
Access Control: This includes the mechanisms used to grant or deny access to systems and data based on an individual's credentials and privileges.
Incident Response: This involves the process of responding to and containing security incidents, including the identification, investigation, and remediation of security breaches.
Ethical Hacking: This involves testing the security of systems and networks by analyzing potential vulnerabilities and exploiting them to gain unauthorized access.
Cyber Security Governance: This involves the establishment and implementation of policies, procedures, and standards to ensure the security of systems and networks.
Network Security: It involves securing the network infrastructure of an organization by installing firewalls, intrusion detection systems and other security devices.
Information Security: It involves the protection of information from unauthorized access, use, disclosure, disruption, modification or destruction.
Application Security: It involves securing the applications and software used by an organization from various cyber threats such as hacking, malware, viruses, and other attacks.
Cloud Security: It involves securing the cloud infrastructure, services, and data against various cyber threats.
Malware Analysis: It involves identifying and analyzing malware, viruses, and other malicious software to identify their source and prevent further infections.
Digital Forensics: It involves the acquisition, preservation, and analysis of digital evidence for use in legal proceedings.
Incident Response: It involves responding to cyber incidents and containing the damage caused by them.
Threat Intelligence: It involves collecting, analyzing and using data to identify potential cyber threats and taking preventive measures to protect against them.
Identity and Access Management: It involves managing access to various resources and systems within an organization, and ensuring that only authorized personnel can access them.
Physical Security: It involves securing the physical infrastructure of an organization such as data centers, servers, and other devices.
