Guide on Software and System Security

Software and System Security is a vital part of information security that is covered under the CISSP certification.

Why It is Important: This domain of security is crucial because it provides protection against threats posed to software and systems that store, handle, and process information. Breaches in this domain can lead to unauthorized access, data theft, system breakdowns or service disruption.

What It Is: Software and System Security involves implementing, managing and controlling security policies and protocols to safeguard digital assets, critical services and sensitive information of an organization. This encompasses application security, information protection processes and procedures, security operations, and secure software development.

How It Works: It works by incorporative protective measures at every level of software and systems. This typically includes encryption, intrusion detection systems, firewalls, anti-malware and regular patching or updates.

Exam Tips: Answering Questions on Software and System Security: Understand the basic principles behind software and system security, and focus on the applications of these principles in different scenarios. Pay particular attention to encryption methods, secure coding practices, understanding vulnerabilities and threats, and the strengths and weaknesses of different security controls. In the exam scenario-based questions are common, so understand the application of concepts rather than just rote learning. Also practice with past exam questions to familiarize yourself with the question format and structure of the CISSP exam.
