Course Introduction and Security Basics
Governance, Compliance and Risk
In the last decade the nature and complexity of security attacks have increased tremendously. From simple attacks, which focused on hacking exposed web pages; we have evolved to stealthy attacks, which focus on the hacker staying hidden for years on end inside the victim’s network with the sole purpose of stealing data. To make matters worse, more and more companies have started to store their data in the cloud, thereby transferring part of the responsibility of securing that data to the cloud service provider. Therefore these days the cloud service is entrusted with the task of providing adequate security to the data and services that it provides to customers. While making a decision to move to the cloud, the two main metrics that enterprises look at tend to be cost and security risk.
Monitoring is usually referred to in the NIST documentation as continuous monitoring. This is done to stress the fact that monitoring nine hours a day for five hours a week, is not true monitoring. True monitoring, is 24/7, nothing else. If it is not 24/7, then it is auditing or sampling. NIST defines the Information Security Continuous Monitoring as maintaining ongoing awareness of information security, vulnerabilities, and threats to support organizational risk management decisions. ISCM should provide an assessment of and analysis of security control effectiveness and of organizational security status in accordance with organizational risk tolerance.
Security control effectiveness is measured by correctness of implementation and by how adequately the implemented controls meet organizational needs in accordance with current risk tolerance.
Organizational security status is determined using metrics established by the organization to best convey the security posture of and organization's information and informational systems, along with organizational resilience given known threat information. This involves maintaining an understanding of threats and threat activities, assessing all security controls, collecting, correlating, and analyzing security-related information, providing actionable communication of security status across all tiers of the organization, and active management of risk by organizational officials.
A highly standardized view of ISCM has the following basic features: Sources of Data, Data collectors and aggregators, Data Storage, Dashboards, Reports, Metrics, Decision Maker. It is essential while monitoring to keep in mind the three dimensions: monitoring the security posture of the organization, monitoring the effective functioning of controls, monitoring for intrusions. The sources of data can be classified into the following types: Network, Perimeter, Endpoint, Infrastructure, and Application.
