What is operational cyber security?

What is operational cyber security?

OPSEC (operational security) is an analytical process that classifies information assets and determines the controls required to protect these assets. OPSEC originated as a military term that described strategies to prevent potential adversaries from discovering critical operations-related data.

What is security threats and its types?

In Information Security threats can be many like Software attacks, theft of intellectual property, identity theft, theft of equipment or information, sabotage, and information extortion.

What is countermeasure computer security?

In computer security a countermeasure is an action, device, procedure, or technique that reduces a threat, a vulnerability, or an attack by eliminating or preventing it, by minimizing the harm it can cause, or by discovering and reporting it so that corrective action can be taken.

How does the OS maintain security?

It has user authentication methods that ensure legitimacy of user access. OS provides antivirus protection against malicious attacks and has inbuilt firewall which acts as a filter to check the type of traffic entering into the system.

What is security life cycle?

The information security lifecycle describes the process to follow to mitigate risks to your information assets.

What is an example of security control?

Examples include physical controls such as fences, locks, and alarm systems; technical controls such as antivirus software, firewalls, and IPSs; and administrative controls like separation of duties, data classification, and auditing.

What is security state explain with examples?

From Wikipedia, the free encyclopedia. A secure state is an information systems security term to describe where entities in a computer system are divided into subjects and objects, and it can be formally proven that each state transition preserves security by moving from one secure state to another secure state.

What is a system security plan?

The purpose of the system security plan (SSP) is to provide an overview of the security requirements of the system and describe the controls in place or planned, responsibilities and expected behavior of all individuals who access the system. It is a core component of DITSCAP.

What are the security plan components?

Elements of a Security Plan

• Physical security. Physical security is the physical access to routers, servers, server rooms, data centers, and other parts of your infrastructure.
• Network security.
• Application and application data security.
• Personal security practices.

What are the four objectives of planning for security?

identify risks, get management input, and develop priorities and consensus on risk mitigation; and. align services and support with business objectives.

What are the 3 ISMS security objectives?

Implementation Guideline Thereby, objectives in an ISMS are the knowledge security objectives for confidentiality, integrity and availability of data.

What is the purpose of risk management?

Guidelines for Risk Management Process Review The purpose of risk management is to identify potential problems before they occur so that risk-handling activities may be planned and invoked as needed across the life of the product or project to mitigate adverse impacts on achieving objectives.

What are the phases of the overall IR development process?

What are the phases of the overall IR development process? The IR process is made up of several phases: preparation, detection and analysis, containment, eradication and recovery, and post-incident activity.

What are the six phases of the incident response cycle?

A well-defined incident response plan should include detailed information about each phase of an attack. The six critical phases of incident response are preparation, identification, containment, removal, recovery, and learning from mistakes.

What is the primary function of the IR policy?

What is the primary function of the IR Policy? The IR policy defines the roles and responsibilities for IR for the CSIRT and for others who will be mobilized in the activation of the plan.

What are the five steps of incident response in order?

The Five Steps of Incident Response

• Preparation. Preparation is the key to effective incident response.
• Detection and Reporting. The focus of this phase is to monitor security events in order to detect, alert, and report on potential security incidents.
• Triage and Analysis.
• Containment and Neutralization.
• Post-Incident Activity.

What are the 6 stages of evidence handling?

Incident response is typically broken down into six phases; preparation, identification, containment, eradication, recovery and lessons learned.

What is the incident response life cycle?

The NIST incident response lifecycle breaks incident response down into four main phases: Preparation; Detection and Analysis; Containment, Eradication, and Recovery; and Post-Event Activity.

What are the seven steps for incident management?

In the event of a cybersecurity incident, best practice incident response guidelines follow a well-established seven step process: Prepare; Identify; Contain; Eradicate; Restore; Learn; Test and Repeat: Preparation matters: The key word in an incident plan is not ‘incident’; preparation is everything.
