Security Administration
Security Administration refers to the policies, procedures, and technical measures put in place to protect an organization's information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. It is a crucial aspect of Information Security which ensures the confidentiality, integrity, and availability of data.
History and Evolution
The field of security administration has evolved significantly since the advent of computer technology:
- 1960s-1970s: Security measures were primarily focused on physical security, with minimal emphasis on digital security. The development of the ARPANET (predecessor to the Internet) led to initial considerations of network security.
- 1980s: With the growth of personal computing and the Internet, security concerns shifted towards digital threats. The Computer Emergency Response Team (CERT) was established by Carnegie Mellon University's Software Engineering Institute in 1988 to address internet security incidents.
- 1990s: This decade saw the introduction of comprehensive security policies, the rise of firewalls, and the beginning of encryption for commercial use. The establishment of organizations like the Internet Society (ISOC) and the development of standards by bodies like International Organization for Standardization (ISO) began to shape formal security practices.
- 2000s onwards: With the proliferation of mobile devices, cloud computing, and the Internet of Things (IoT), security administration has become more complex and vital. The focus has shifted to real-time threat detection, incident response, and advanced persistent threats (APT).
Key Components
The following are key elements of security administration:
- Policy Development: Establishing rules and guidelines that define acceptable use, access controls, and incident handling procedures.
- Risk Management: Identifying, evaluating, and prioritizing risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability and/or impact of unfortunate events.
- Access Control: Implementing mechanisms like user authentication, authorization, and accounting (AAA) to ensure that only authorized personnel can access specific resources.
- Security Monitoring: Continuous monitoring of systems for anomalies, intrusion detection systems (IDS), and security information and event management (SIEM) systems.
- Incident Response: Procedures for responding to security breaches or incidents, including containment, eradication, and recovery processes.
- Audit and Compliance: Regular audits to ensure that security measures are in place and functioning as intended, along with compliance to various regulations like GDPR, HIPAA, etc.
- User Training and Awareness: Educating employees about security policies, safe computing practices, and social engineering threats.
