What is the incident response cycle?

What is the incident response 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 4 phases of the incident response lifecycle defined by NIST?

Develop incident response procedures They should be based on the incident response policy and plan and should address all four phases of the incident response lifecycle: preparation, detection & analysis, containment, eradication and recovery, and post-incident activity.

Which stage is determining whether an incident has taken place and assessing how severe it might be followed by notification of the incident to stakeholders?

Identification involves determining whether an incident has taken place and assessing how severe it might be, followed by notification of the incident to stakeholders.

What is an incident response policy?

The Incident Response policy is as follows: Management responsibilities and procedures should be established to ensure a quick, effective, and orderly response to Security Incidents. Security Events should be reported through appropriate management channels as quickly as possible.

What is the correct order of the following incident response steps?

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

What is the 1st step in a cyber incident response plan?

The first priority is to prepare in advance by putting a concrete IR plan in place. Your organization should establish and battle-test a plan before a significant attack or breach occurs. It should address the following phases as defined by NIST Computer Security Incident Handling Guide (SP 800-61):

Which is the first step in the incident management process?

The first step in the life of an incident is incident identification. Incidents come from users in whatever forms the organization allows.

What are the four steps of the incident response process?

What are the Four Steps of an Incident Response Plan?

1. Preparation.
2. Detection and Analysis.
3. Containment, Eradication, and Recovery.
4. Post-incident Activity.

What are the two incident response phases?

NIST breaks incident response down into four broad phases: (1) Preparation; (2) Detection and Analysis; (3) Containment, Eradication, and Recovery; and (4) Post-Event Activity.

What are the three phases of incident response?

Detection engineer Julie Brown breaks down the three phases of incident response: visibility, containment, and response.

What are two incident response phases choose two group of answer choices?

Question 39What are two incident response phases? (Choose two.) prevention and containment confidentiality and eradication mitigation and acceptance containment and recovery risk analysis and high availability detection and analysis Correct! Correct!

What are two incident response phases choose two quizlet?

The containment, eradication, and recovery phase includes choosing a containment strategy and evidence gathering and handling.

What is the first rule of incident response investigation quizlet?

What is the first rule of incident response investigation? When deleted, a file is removed from its original place on the storage device and is only available in the recycle bin. What is a software bomb? The team should confirm the existence, scope, and magnitude of the event and then respond accordingly.

Which two reasons describe why WEP is a weak protocol choose two group of answer choices?

Which two reasons describe why WEP is a weak protocol? (Choose two.)

• WEP uses the same encryption features as Bluetooth.
• Everyone on the network uses a different key.
• The key is static and repeats on a congested network.
• The default settings cannot be modified.
• The key is transmitted in clear text. Explanation:

Which two values are required to calculate annual loss expectancy choose two?

In calculating risk, there are two general formulas that are used: SLE (single loss expectancy) and ALE (annualized loss expectancy). SLE is the starting point to determine the single loss that would occur if a specific item occurred. The formula for the SLE is: SLE = asset value × exposure factor.

What is the most difficult part of designing a cryptosystem?

Key exchange and management are often considered the most difficult part of designing a cryptosystem. Many cryptosystems have failed because of mistakes in their key management, and all modern cryptographic algorithms require key management procedures.

Which three protocols can use AES?

Which three protocols can use Advanced Encryption Standard (AES)? (Choose three.)

• WPA.
• TKIP.
• WPA2.
• 802.11i.
• 802.11q.
• WEP. Explanation: Various protocols can be used to provide secure communication systems. AES is the strongest encryption algorithm.

How is annual loss expectancy calculated?

Now we can combine the monetary loss of a single incident (SLE) with the likelihood of an incident (ARO) to get the annualized loss expectancy (ALE). The ALE represents the yearly average loss over many years for a given threat to a particular asset, and is computed as follows: ALE = SLE x ARO.

What is the ROSI calculation?

The ROSI calculation combines the quantitative risk assessment and the cost of implementing security counter measures for this risk. In the end, it compares the ALE with the expected loss saving.

How much is the exposure factor in single loss expectancy?

Where the exposure factor is represented in the impact of the risk over the asset, or percentage of asset lost. As an example, if the asset value is reduced by two thirds, the exposure factor value is 0.66. If the asset is completely lost, the exposure factor is 1.

What is annual loss exposure?

Annualized Loss Exposure (ALE) is the most recognized and focused result from quantitative analysis within the RiskLens platform. What it is Annualized Loss Exposure is the key metric in the simplest form of how we communicate risk.

How do you calculate exposure factor?

The percentage of the asset value that would be lost is the exposure factor (EF). The dollar (or other currency) amount that would be lost if the threat was realized is the single loss expectancy (SLE), and is computed using the following formula: SLE = asset value x exposure factor.
