- A
Revoke the suspicious sessions and require all users to re-authenticate with MFA before granting access to cloud applications.
This immediately stops the ongoing threat and enforces a stronger authentication method for future access.
- B
Ask the affected users to change their passwords and monitor their accounts for further suspicious activity.
Why wrong: Password reset alone is insufficient because the attacker may have already established persistence or used the credentials elsewhere.
- C
Lock all user accounts and require the IT team to manually verify each user's identity before unlocking.
Why wrong: Locking all accounts is too extreme and will severely impact business operations; it is not proportionate to the evidence.
- D
Disable SSO immediately and require users to authenticate directly with the cloud applications.
Why wrong: Disabling SSO is a drastic measure that will cause user friction and may not prevent the attacker from using stolen credentials directly.
CCSP Cloud Security Operations Practice Question
This CCSP practice question tests your understanding of cloud security operations. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A multinational corporation uses a hybrid cloud model with on-premises data centers and the AWS cloud. They have implemented a Cloud Access Security Broker (CASB) to enforce security policies. Recently, the security team noticed that users are accessing cloud applications from unusual geographic locations and downloading large volumes of data. The CASB logs show that the users authenticated using single sign-on (SSO) with valid credentials. The company has not enabled multi-factor authentication (MFA) for all users due to a previous pushback from the user community. The security team suspects a credential theft incident. What is the BEST course of action to mitigate the risk and respond to the potential incident?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Revoke the suspicious sessions and require all users to re-authenticate with MFA before granting access to cloud applications.
Option C is correct because immediately revoking the suspicious sessions and requiring MFA re-authentication stops the potential attack and enforces stronger security. Option A is wrong because disabling SSO would disrupt business operations and not address the root cause. Option B is wrong while resetting passwords helps, without MFA the new passwords could also be stolen. Option D is wrong because locking all accounts is too disruptive and assumes all users are compromised, which is not indicated.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
